### Added
- **HTTP Streamable-HTTP MCP transport (`navig mcp serve --transport http`)**: NAVIG can now be exposed as an HTTP MCP server for AI assistants that connect via URL rather than stdio/WebSocket. Implements the MCP 2024-11-05 Streamable HTTP spec: `POST /mcp` (JSON-RPC 2.0), `GET /mcp` (SSE keepalive stream), `OPTIONS /mcp` (CORS preflight), `GET /health` (liveness). Optional Bearer-token auth (`--token`). `--print-config` prints a Perplexity-ready MCP Server URL, VS Code `mcp.json` snippet, and Claude Desktop config block. `_build_http_app()` factory extracted for testability. `generate_perplexity_mcp_config()` helper returns the Perplexity connector dict. Default port: 3001. 12 tests in `tests/test_mcp_http.py` (stub-based, no live aiohttp import required).
- **Perplexity AI outbound connector (`navig/connectors/perplexity/`)**: New `PerplexityConnector` integrating Perplexity Sonar API as a search-only connector. Domain: `AI_RESEARCH`. Auth: `PERPLEXITY_API_KEY` env var (no OAuth, no vault dependency). `search()` POSTs to `https://api.perplexity.ai/chat/completions` (model: `sonar`) and returns a `Resource` for the synthesized answer plus citation-URL resources. `health_check()` measures API latency. `fetch()` and `act()` return not-supported values as per connector contract. Registered in `connector_cmd.py` auto-discovery. 17 tests in `tests/connectors/test_perplexity.py`.
- **Connector Engine (Phase 1 — Gmail + Google Calendar)**: New `navig/connectors/` package providing a unified integration layer for external services. Core infrastructure: `BaseConnector` ABC with `search`/`fetch`/`act`/`health_check` contract, `ConnectorRegistry` thread-safe singleton, `ConnectorManifest` metadata, `CircuitBreaker` per-connector resilience, `ConnectorAuthManager` vault+OAuth PKCE bridge. Shared types: `ConnectorDomain` (13 domains), `ConnectorStatus`, `Resource`, `Action`/`ActionResult`, `HealthStatus`, `ResourceType` enums+dataclasses. Error hierarchy: `ConnectorError` → `ConnectorAuthError`, `ConnectorNotFoundError`, `ConnectorDegradedError`, `ConnectorAPIError`, `ConnectorRateLimitError`. Phase 1 connectors: **Gmail** (`navig/connectors/gmail/`) — search, fetch, send/reply/archive/label/delete via Gmail API v1; **Google Calendar** (`navig/connectors/google_calendar/`) — search, fetch, create/update/delete events, conflict checking via Calendar API v3. **SmartLinker** cross-connector relationship engine links Gmail↔Calendar via date mentions and attendee overlap. CLI commands: `navig connector list|status|connect|disconnect|search|fetch|health`. 62 tests covering all modules.
- **Vault-backed Telegram owner identity (`telegram.user_id`)**: `navig/messaging/secrets.py` — new `resolve_telegram_uid(raw_config=None) → str | None` and `ensure_telegram_uid(vault, raw_config) → str` following the exact pattern of `resolve_telegram_bot_token`. Resolution order: vault v2 labels (`telegram/user_id`, `telegram.user_id`, `telegram_user_id`) → vault v1 (`telegram/user_id` key) → `NAVIG_TELEGRAM_UID` env var → `~/.navig/.env` → `telegram.user_id` in config (deprecated, logs warning). `ensure_telegram_uid` prompts once on first interactive run, stores permanently to vault v2, and raises `RuntimeError` in headless/CI mode with a clear `NAVIG_TELEGRAM_UID` instruction. Vault write failure is fatal (does not silently proceed with unsaved UID). `navig/daemon/telegram_worker.py` and `navig/messaging/registry.py` `_telegram_config()` now include `owner_uid` in the returned dict. `navig/onboarding/steps.py` `_step_telegram_bot()` prompts for the owner Telegram user ID after a successful token save and stores it to vault v2 + `.env`. `navig/commands/vault.py` `vault_set`/`vault_get` now dual-write dot-notation keys to vault v2 so `navig vault set telegram.user_id <uid>` and `navig vault get telegram.user_id` round-trip correctly via the v2-first resolution chain. `tests/test_telegram_uid_resolution.py` — 10 tests covering all resolution paths, precedence rules, headless guard, happy-path vault write, and vault-write failure.

 in `pyproject.toml` and added to `requirements.txt`. Users who installed with bare `pip install navig` or the official installers previously received only the numbered fallback picker (Tier 3); arrow-key navigation (Tier 2) now works out of the box. The `navig[interactive]` extra is preserved as a documented alias. `install.ps1` and `install.sh` updated to install `navig[interactive]` so the extra is always resolved regardless of install path.
- **Optional fzf install in official installers**: `install.ps1` now tries `winget install junegunn.fzf` after `navig` is installed; prints a manual hint if winget is unavailable. `install.sh` tries `brew`/`apt-get`/`pacman`/`dnf` in order based on detected OS; prints a manual hint if no package manager succeeds.
- **Picker degradation hints**: `navig/cli/selector.py` now prints one-time per-session hints to stderr on interactive TTYs when falling through tiers — `"Tip: install fzf …"` when falling from Tier 1 to 2, `"Tip: pip install navig[interactive]"` when falling from Tier 2 to 3. `navig/onboarding/steps.py` `_step_core_navig` prints a fzf install hint when `fzf` is absent at `navig init` time.

- **Automatic Nerd Font detection and terminal capability persistence**: `navig/ui/_capabilities.py` — new module with `probe_nerd_font()` (Windows: `winreg` + font-dir glob; macOS: `~/Library/Fonts`; Linux: `~/.local/share/fonts` + `fc-list` fallback), `read_terminal_json`/`write_terminal_json` for `~/.navig/terminal.json` caching, and `try_install_nerd_font()` (calls `Install-NerdFont.ps1` via `pwsh` on Windows; prints one-liner on macOS/Linux). `navig/ui/theme.py`: new `NERD_FONT_AVAILABLE` bool (env override `NAVIG_NERD_FONT=1/0` → `terminal.json` cache → active probe; skipped in CI/NO_COLOR). `navig/ui/icons.py`: `nf_icon()` now guards on `NERD_FONT_AVAILABLE` and falls back to `icon()` on unconfigured terminals. `navig/onboarding/steps.py`: new `terminal-setup` bootstrap step (phase 1, `on_failure="skip"`) that probes at `navig init` time, offers a Y/n install prompt on interactive TTYs, and writes `terminal.json` in all paths. `install.ps1`: `Write-TerminalCapabilities` writes `terminal.json` after `Initialize-NavigConfig`. `install.sh`: `_write_terminal_json` writes `terminal.json` after the install marker.
- **Cross-platform Nerd Font integration**: `scripts/Install-NerdFont.ps1` — idempotent PS7.2+ installer; auto-detects JetBrainsMono Nerd Font, downloads from GitHub releases, installs to OS-appropriate font directory (C:\Windows\Fonts, ~/Library/Fonts, ~/.local/share/fonts), patches VS Code `settings.json`, and patches Windows Terminal `settings.json` on Windows. `scripts/navig-icons.psm1` — single-source Nerd Font glyph registry (`$NAVIG` hashtable, 24 keys) with UTF-8 console encoding guard and `[char]::ConvertFromUtf32()` for supplementary codepoints. `scripts/navig-colors.psm1` — semantic ANSI color wrappers (`Set-NavColor`) with Windows `ENABLE_VIRTUAL_TERMINAL_PROCESSING` guard via P/Invoke. `scripts/navig-statusbar.psm1` — `Show-NavStatus` Powerline status bar renderer with platform OS-icon injection (Windows/macOS/Linux). Python: `navig/ui/icons.py` extended with `_NF_ICONS` dict (24 Nerd Font codepoints) and `nf_icon()` function that falls back to `icon()` for unknown keys.

### Changed
- **Emoji-to-icon registry migration**: Replaced all hardcoded emoji literals covered by the spec in `navig/console_helper.py` (`confirm_operation()` — `⚠️`, `📝`, `ℹ️` replaced via lazy `_ni` import to avoid startup cost), `navig/gateway/channels/telegram_commands.py` (~25 occurrences: bridge status, model tier display, provider picker buttons, voice/focus/session status, debug mode, warn messages), and `packages/telegram-bot-navig/plugins/nlp_aliases.py` (all 10 `_ACTIONS["emoji"]` values + error message). All glyphs now resolve through the `navig.ui.icons` registry with `SAFE_MODE` ASCII fallbacks.

### Internal / Refactor
- **`navig/cli/middleware.py` extracted from `__init__.py`**: New module with four helpers called from `main()` — `init_operation_recorder()`, `init_debug_logger()`, `register_fact_extraction()`, `init_proactive_assistant()`. `__init__.py` reduced from 1491 → 1250 lines (−241). No behaviour change; 39/39 regression tests pass.
- **AI command surface rationalisation (Phase 1)**: Reduces 7+ overlapping AI entry points to a clean two-command surface (`navig ask` + `navig agent`). Changes: (1) `navig ai ask`, `navig ai explain`, `navig ai suggest`, `navig ai diagnose` are deprecated — each prints a `deprecation_warning()` redirecting to `navig ask`. (2) `navig chat` is deprecated → `navig ask`; command is unhidden so the warning appears in `--help`. (3) `navig explain` removed from `_EXTERNAL_CMD_MAP` (all three sub-commands were `ch.warn("not yet implemented")` stubs — nothing removed for users). (4) `navig brain` registered in `_EXTERNAL_CMD_MAP` — the prompt-file management module (`brain.py`, 201 lines) was fully implemented but unreachable; it is now accessible as `navig brain prompts list/get/set/reload`. AI management commands (`navig ai models`, `providers`, `airllm`, `login`, `logout`, `memory`) are unchanged.
- **AI intent preview controls on `navig ask` (Phase 2, non-breaking)**: `navig ask` now infers mode via `navig.routing.detect.detect_mode()` and injects route metadata (`ask_detected_mode`, `ask_detected_confidence`, `ask_detected_reasons`) into the ask options payload. New flags: `--plan` prints inferred route and exits without executing; `--plan --execute` prints route then executes. Default `navig ask` behavior is unchanged.

### Fixed
- **Ruff style/correctness cleanup (700+ violations across 50+ files)**: Seven violation categories eliminated: (1) **E741** — renamed 12 ambiguous `l` loop variables to `ln`/`layout`/`lnk`/`lbl`/`item` across `agent/plan_execute.py`, `agents/inbox_router.py`, `commands/agent.py`, `commands/ahk.py`, `commands/links.py`, `commands/monitoring.py`, `deploy/history.py`, `gateway/channels/task_card.py`, `local_operations.py`, `onboarding/steps.py`, `workspace.py`; (2) **W293/W191/E731** — blank-line whitespace (`core/execution.py`), tab→space in `migrations/__init__.py`, lambda→def in `providers/__init__.py`; (3) **I001/SIM114/UP034/C420** — 14 auto-fixes (import sort, collapsed if-arms, redundant parens, dict-comprehension); (4) **B904** — added `raise … from None/exc` to 12 bare re-raise sites in `agent/mcp_client.py`, `cli/recovery.py`, `commands/host.py`, `commands/import_cmd.py`, `commands/telegram.py`, `commands/vault.py`, `commands/webdash.py`; (5) **F811** — removed duplicate `msg_trace_path()` in `platform/paths.py`, redundant `Path` re-import in `commands/skills.py`; (6) **B023** — added `# noqa: B023` for intentional semaphore closure in `agent/conversational.py`; (7) **S101/S602** — `# noqa` for runtime invariant asserts in `agent/mcp_client.py` IPC guards/`agent/tools/skill_tools.py` context guards, and intentional `shell=True` subprocess in `commands/remote.py`/`remote.py`.
- **DRY async bridge `navig/commands/_async_utils.py`**: Extracted duplicated `_run()` async-to-sync helper from `ask.py` and `connector_cmd.py` into a shared `run_sync()` function. Both commands now import `run_sync as _run` from the shared module.
- **`Optional[X]` → `X | None` modernization (PEP 604)**: Updated 15+ files across `cli/middleware.py`, `connection_pool.py`, `commands/onboard.py`, `core/shared_config.py`, `desktop/tray_app.py`, `gateway/deck/__init__.py`, `installer/__init__.py`, `mcp/tools/__init__.py`, `mesh/sync_manager.py`, `messaging/secrets.py`, `modes/manager.py`, `onboarding/telemetry.py`, `plugins/__init__.py`, `tools/sandbox.py`, `tunnel.py`, `webhooks/signatures.py`, `yaml_utils.py` to use Python 3.10+ union-type syntax.
- **Lazy logger formatting**: Replaced f-string arguments in `logger.*()` calls with `%s` placeholder pattern (avoids formatting cost when log level is disabled) across `workspace.py`, `webhooks/receiver.py`, `tasks/worker.py`, `commands/host.py`, `mesh/sync_manager.py`.
- **Ruff F841 dead variable cleanup (36 violations across 35 files)**: Removed dead local variable assignments across agent, browser, gateway, commands, core, memory, onboarding, selfheal, tools, tui, tunnel, ui, and voice modules. Removed: `port`/`host` (ears.py stub), `tagged_count` (prompt_caching.py), `navig_cmd` (service.py), `result=` (imap_email.py — bare call preserved), `system_prompt` (browser/orchestrator.py), `vault=` (vault_bootstrap.py — bare call preserved), `thinking=` (telegram_refiner.py — bare await preserved), `elapsed`/`t0`/`import time` (telegram.py), `model_name` (telegram_keyboards.py → `_`), `file_path` (config_watcher.py), `navig_path`/`cutoff`/`timestamp_str` (commands/agent.py), `fork_url` (contribute.py — bare `fork_repo()` call preserved), `config` (history.py + main.py), `ops` (insights.py), `resp` (matrix.py + matrix_admin.py), `temp_options` (monitoring.py), `password=` (proactive.py — bare prompt preserved), `context` dict (ahk.py), `response=` (ai.py), `event_key` (plugins.py), `fg_off` (genesis.py), `url_len` (tools/web.py), `channels_dir` (tui/resolvers.py), `remote_host` copy-paste bug (tunnel.py), `ico_ai` (ui/summary.py), `stt` (voice/pipeline.py). Cascade-fixed 6 F401 imports (`timedelta`, `get_config_manager`, `Console`, `import time`, `StreamingSTT`). Added `pass` to two empty `if`-bodies. `# noqa: F841` for intentional sentinel/stub patterns (doctor.py, email.py, database_advanced.py, ssh_healer.py, main.py).
- **Ruff F401/F841 lint cleanup (46 violations across 34 files)**: Removed 41 unused imports (`F401`) across 29 files via `ruff --fix` (excluding `navig/cli/__init__.py` re-exports). Manually fixed 5 dead local variable assignments (`F841`): `start_time` in `tools/executor.py`, unused `config_manager` in `commands/config.py:migrate()`, dead `parts`/`cmd_name` in `core/kernel.py` mock loop, `use_shell` in `agent/background_task.py`, and `want_plain` in `commands/docs_cmd.py`.
- **Ruff auto-fix batch (71 issues across 45 files)**: Applied safe auto-fixes for `I001` (unsorted imports), `W293`/`W291` (whitespace on blank lines / trailing whitespace), `F541` (f-strings without placeholders), and `W605` (invalid escape sequences) across the `navig/` source tree and selected test files. Promotes module-level imports and removes dead whitespace produced during prior AI-generated edits.
- **Test isolation — `test_plans_command.py`, `test_spaces_briefing.py`, `test_spaces_next_action.py`**: All three test files converted from `monkeypatch.setattr(Path, "home", ...)` to `monkeypatch.setenv("NAVIG_CONFIG_DIR", str(config_dir))`, matching the `paths.config_dir()` resolution path used by `navig/spaces/resolver.py`, `navig/plans/context.py`, and related modules. Previously these tests created space/plan directories under `home / ".navig" / ...` which was never discovered because the source code reads from `NAVIG_CONFIG_DIR`, not `Path.home()`. All 65 tests across the three suites now pass.
- **Telegram providers screen — unconfigured cloud providers now show `🔑` stub rows**: `_handle_providers()` in `navig/gateway/channels/telegram_commands.py` previously skipped all unready providers, showing only "ℹ️ No configured providers found." Changed to: (1) when a cloud provider has `requires_key=True` and no vault key is stored (`vault_has_key=False`), a single-button stub row `{emoji} {DisplayName} 🔑` with `callback_data=prov_cfg_{id}` is added to the keyboard — inviting the user to configure the key; (2) when a vault key exists but is not validated, the provider is still hidden (no stub) to avoid confusion; (3) the "no ready providers" informational line changed to "ℹ️ No vault-backed cloud providers are ready." for clarity. All 37 `test_telegram_reminders.py` tests pass.
- **`SessionStore._generate_session_id()` collision guard**: Promoted `import secrets` and `import threading` to module level; added `_SESSION_ID_LOCK`, `_SESSION_ID_LAST_TS`, `_SESSION_ID_COUNTER` module-level state so IDs within the same second are monotonically incremented (wrapping at 0xFFFF) instead of random — preventing collision under high-concurrency session creation.
- **`ConfigManager` test isolation — legacy file discovery and `global_config_dir` semantics**: `ConfigManager.__init__` (`navig/config.py`) previously set `global_config_dir` unconditionally to `paths.config_dir()` (real `~/.navig`), causing `_get_config_directories()` to never search the explicit `config_dir` supplied in tests. This broke all five legacy-format host/app lookup tests. Fix: `_get_config_directories()` now returns `[app_config_dir, base_dir]` (early exit) when an explicit `config_dir` was passed, providing full isolation without polluting the real `~/.navig`. `global_config_dir` property semantics are unchanged (still driven by `NAVIG_CONFIG_DIR` env var or `~/.navig`). `HostManager.save()` (`navig/core/hosts.py`) was independently saving to `global_config_dir / "hosts"` instead of `hosts_dir` (i.e. `base_dir / "hosts"`); corrected to use `self._config.hosts_dir` so read and write paths are always consistent. 24/24 `test_config.py` + 9/9 `test_wave10_paths.py` pass.
- **Ruff lint cleanup** (`navig/ai.py`, `navig/commands/config.py`, `navig/config.py`, `navig/gateway/channels/telegram.py`, `navig/gateway/channels/telegram_commands.py`): 12 auto-fixed issues — I001 import ordering, B010 `setattr` with constant attribute, F811 redefined `random` import inside function body. Inline `import threading as _thr` / `import logging as _log` in `config.py` background-validation thread promoted to module-level to avoid `UnboundLocalError` when the fast-path cache-hit branch was not taken.
 The script previously continued through dependency detection and exited with `pip not available`, even in preview mode. `main()` now short-circuits early in dry-run mode after rendering a non-mutating preview (`Action` + `Dry run complete`) and exits successfully.
- **`install.sh --action <value>` now validates unsupported actions early**: Unknown values (e.g. `--action bogus`) previously fell through and failed later with unrelated environment errors. `main()` now rejects invalid actions immediately with a clear `invalid action` failure message and non-zero exit.
- **`navig ask` (and any host picker) silently discards fzf selection**: `fzf_or_fallback()` (`navig/cli/selector.py`) built its reverse-lookup map from the raw padded display strings (e.g. `"o2switch                   "`) but compared against fzf's `.strip()`ped stdout (`"o2switch"`). When `description` is empty the entry ends with trailing whitespace that fzf strips, so `index_map.get()` always returned `None` and `require_active_server` / `require_active_host` raised `typer.Exit(0)` even after a valid selection — causing the picker to re-appear on every command. Fixed by building `index_map` with stripped keys; entries with non-empty descriptions are unaffected.
 - **`navig ask` now resolves active host per invocation and avoids localhost auto-bootstrap bias**: `ask_ai` now resolves host from CLI options + active server + compatibility `active_host` key and calls `require_active_server(..., allow_local_bootstrap=False)` when resolution is still empty. This prevents silent localhost pivoting in ask flow while preserving existing bootstrap behavior for other commands. Missing OpenRouter key errors in ask flow are now host-aware and include source checks (`OPENROUTER_API_KEY`, `ai.api_key`, `openrouter_api_key`) with actionable setup guidance.
- **`navig ask` host guards and options safety**: `ask_ai` now tolerates `options=None`, validates resolved host existence before loading config, and converts missing/invalid host config conditions into clear `Exit(2)` user guidance instead of low-signal exceptions.
- **Host launcher non-TTY guard restored**: `smart_launch()` now requires both `stdin` and `stdout` to be TTY before opening the interactive selector. In subprocess/non-interactive contexts it now consistently prints the `Non-TTY detected` hint and exits cleanly with status 0 (`navig host --help` guidance), preventing accidental interactive picker rendering in CI/tests.
- **Telegram provider/model selection UX overhaul**: (1) All providers now display in a uniform 2-per-row grid (ready providers show ✅, unconfigured show 🔑). (2) Clicking any provider opens the model picker — providers without API keys show a ⚠️ banner instead of being dead buttons. (3) Static `picker_map` dict replaced with dynamic registry lookup so new providers work automatically. (4) Individual model and bulk-activate assignments now update the primary LLM Mode Router (persisted to config) in addition to the optional hybrid router, so `/models` and `/providers` displays reflect changes immediately. (5) `/models` is now a read-only status view — tier switching is done exclusively via `/providers`.
- **`llama.cpp` onboarding now asks for local server URL**: Selecting `llama.cpp` in `navig init` (`ai-provider` step) now prompts for endpoint URL (default `http://127.0.0.1:8080`) instead of silently completing as a generic local provider. The entered value is persisted under `llm_router.provider_base_urls.llamacpp` in `.navig/config.yaml` for reuse.
- **`navig init --provider` now correctly re-runs the `ai-provider` step** (#79): Previously, `_already_completed()` fired for the `jump_to_step` target regardless of whether the caller explicitly asked to re-run it. Because `~/.navig/onboarding.json` preserved the prior `ai-provider: completed` record (and `force=False` when using `--provider`), the step was silently skipped and the engine fell through to `web-search-provider`. The guard in `OnboardingEngine.run()` (`navig/onboarding/engine.py`) now carves out the explicit jump target: `is_jump_target = bool(self._config.jump_to_step) and step.id == self._config.jump_to_step; if not is_jump_target and self._already_completed(step.id): continue`.
- **Progress display during `navig init --provider` no longer shows misleading `[5/18 27%]`** (#79): When `jump_to_step` is active, only the target step and the tail steps execute, so the `[N/total pct%]` format was confusing — the review step (last to run) printed `[5/18 27%]` which looked like an early crash. `run_engine_onboarding()` (`navig/onboarding/runner.py`) now uses `[step N] · Title...` format when `jump_to_step` is set.
- **Telegram provider picker "Couldn't open … picker" error eliminated** (#58): `answerCallbackQuery` is now sent to Telegram *before* `_show_provider_model_picker` is called in `_handle_provider_callback` (`telegram_keyboards.py`), preventing the loading-spinner timeout and removing the erroneous `show_alert` error toast that appeared when the picker's internal failure cascaded through the `@error_handled` recovery path.
- **Telegram provider picker oversized-keyboard crash fixed** (#58): `_show_provider_model_picker` (`telegram_commands.py`) previously used `page_size = max(1, len(models))`, placing all models on a single page. For providers with large live model lists (e.g. OpenRouter with 200+ entries) this produced a keyboard that exceeded Telegram's message-size limit, causing `send_message` to throw and triggering the double-failure error path. The page size is now capped at `_PAGE_SIZE = 20`. ⬅️ Prev / Next ➡️ navigation buttons appear automatically when `total_pages > 1`, using the existing `prov_page_{prov_id}_{page}` callback format.

### Changed
- **Onboarding UX polish — console_helper migration + tests**: Migrated all remaining `sys.stdout.write` calls in `navig/onboarding/runner.py` (progress display, welcome banners, pause/complete messages) and interactive menus in `navig/onboarding/steps.py` (AI provider picker, fallback provider, web-search provider, skills activation, Google SA prompt, review step messages) to `console_helper` (`ch`) for consistent Rich-based output. Added 23 new tests: 17 renderer function tests (`test_onboarding_renderer.py`) covering success/skipped/failure/in-progress display and label resolution, plus 6 review step tests (`test_onboarding_review_step.py`) covering confirm flow, jump-to-step validation, phase-grouped summary, and step metadata. Updated 3 existing tests to mock `ch` module instead of `sys.stdout`.
- **AI provider onboarding source UX upgrade**: `ai-provider` now uses a shared provider source scanner (`env`/`vault`/`config`) for consistent detection, prompts to import environment keys into vault when found, and offers an optional lightweight post-selection connectivity check. `navig init --status` now uses the same scanner to keep provider-source reporting aligned with onboarding.
- **Storage path centralization (phase 1, wave 10)**: Replaced `Path.home() / ".navig"` fallbacks in `navig/config.py` (`ConfigManager.global_config_dir`), `navig/ai.py` (`_get_conv_store()` — migrated to `paths.data_dir()`), `navig/cache_store.py` (`global_cache_dir()` — migrated to `paths.cache_dir()`), `navig/ai_context.py` (`AIContextManager.__init__` default), and in `navig/daemon/supervisor.py`, `navig/daemon/entry.py`, `navig/daemon/service_manager.py` (module-level `NAVIG_HOME` constants). `supervisor._resolve_log_dir()` simplified to a single `paths.log_dir()` call, removing a redundant lazy-import pattern.
- **Storage path centralization (phase 1, wave 9)**: Replaced `Path.home() / ".navig"` fallbacks in `navig/vault/core.py` (`CredentialsVault.DEFAULT_VAULT_PATH`), `navig/memory/user_profile.py` (`_get_memory_dir()`), `navig/memory/snapshot.py` (`_get_snapshot_dir()`), `navig/memory/paths.py` (`navig_home()` — legacy `NAVIG_HOME` preserved, now falls back to `paths.config_dir()`), and `navig/ipc_pipe.py` (`_PROMOTED_FLAG`). Updated docstring examples in memory storage, knowledge_base, indexer, and conversation modules.
- **Storage path centralization (phase 1, wave 8)**: Replaced `Path.home() / ".navig"` fallbacks in `navig/desktop/tray_app.py` (module-level `LOG_DIR`, `NAVIG_DIR` constants and three function-body daemon-path lookups), `navig/inbox/watcher.py` (`_global_inbox_dir()`), `navig/inbox/store.py` (`_inbox_db()`), `navig/identity/store.py` (`get_identity_store()` default), and `navig/gateway/channels/telegram_sessions.py` (`SessionManager.__init__` default). Inbox and SessionManager migrate to `paths.data_dir()`; tray constants use `paths.config_dir()`.
- **Storage path centralization (phase 1, wave 7)**: Replaced `Path.home() / ".navig"` fallbacks in `navig/modes/manager.py` (`_navig_home()`), `navig/onboarding/runner.py` (both `navig_dir` locals), `navig/mcp_manager.py` (`MCPManager.__init__` default), and `navig/providers/auth.py` (`AuthProfileManager.__init__` default) with `paths.config_dir()`.
- **Storage path centralization (phase 1, wave 6)**: `navig/routing/trace.py` (`TRACE_LOG_PATH`) and `navig/perf/profiler.py` (`PERF_DIR`) module-level constants now use `navig.platform.paths.config_dir()` instead of `Path.home() / ".navig" / ...`. Both are relocatable via `NAVIG_CONFIG_DIR`.
- **Storage path centralization (phase 1, wave 5)**: `navig/settings/resolver.py` — replaced the try/except `navig_config_dir()` / `Path.home()/.navig` fallback in `_global_settings_dir()` with a direct `paths.config_dir()` call. The bare `except Exception` escape hatch is removed; `NAVIG_CONFIG_DIR` overrides now propagate correctly through settings resolve, layer lookup, and `SettingsResolver.set()`.
- **Storage path centralization (phase 1, wave 4)**: Gateway runtime defaults now resolve through `navig.platform.paths.config_dir()` in `navig/gateway/audit_log.py` and `navig/gateway/billing_emitter.py`, replacing hardcoded `~/.navig/runtime/*.jsonl` defaults.
- **Storage path centralization (phase 1, wave 3)**: `navig/commands/config.py` now uses `navig.platform.paths.config_dir()` for global config-root resolution (`config validate --scope global`, legacy migration source/target roots, and `config schema install --scope global`).
- **Storage path centralization (phase 1, wave 2)**: `navig/spaces/resolver.py` now resolves global spaces via `navig.platform.paths.config_dir()` instead of hardcoded `~/.navig/spaces`, improving consistency with `NAVIG_CONFIG_DIR` overrides.
- **Storage path centralization (phase 1)**: Replaced hardcoded `~/.navig` lookups with `navig.platform.paths` in startup fast-status context, plugin-cache lookup, and plan-context default space resolution (`navig/main.py`, `navig/plans/context.py`, `navig/agent/tools/plan_tools.py`). This improves relocatability under `NAVIG_CONFIG_DIR` / `NAVIG_DATA_DIR` while preserving legacy plugin-cache fallback behavior.
- **CLI tunnel alias cleanup**: Removed hidden deprecated tunnel aliases `start`, `stop`, `restart`, and `status` from `navig/cli/__init__.py`; canonical tunnel commands remain `run`, `remove`, `update`, and `show`.
- **CLI web alias cleanup**: Removed hidden deprecated top-level aliases `webserver-list-vhosts`, `webserver-test-config`, and `webserver-reload` from `navig/cli/__init__.py`; canonical `navig web ...` commands remain unchanged.
- **CLI dual-registration dead code removal**: Removed ~305 lines of inline `dispatch_app`, `contacts_app`, and `cron_app` definitions from `navig/cli/__init__.py`. All three already had canonical external implementations in `navig.commands.dispatch` and `navig.commands.cron`, registered via `_EXTERNAL_CMD_MAP`. The inline stubs (including `_LazyDispatchGroup`, `_LazyContactsGroup` TyperGroup subclasses and full 7-command `cron_app`) were dead code that could never be reached. File reduced from 9,938 to 9,633 lines. Commands `navig dispatch`, `navig contacts`, and `navig cron` continue working via their external modules.
- **GitHub practices directive**: Added `.github/instructions/github-practices.instructions.md` — authoritative one-PR-per-issue policy, pre-analysis comment requirement, PR body quality standards, issue comment encoding rules (no literal `\n`, no C0 control characters), issue lifecycle labels, and anti-pattern catalogue. Applied to all AI agents and human contributors.
- **Git workflow rule #9**: Added one-issue-per-PR rule to `git.instructions.md` — batch PRs are explicitly forbidden; each fix/feature requires its own branch and a single `Closes #N`.
- **Copilot PR checklist extended**: `copilot-instructions.md` checklist now requires `Closes #N` in PR body, a prior issue analysis comment, and clean comment encoding (real newlines, no C0 chars). Added `## GitHub Practices` reference section.
- **Pull request template overhauled**: `pull_request_template.md` now leads with `## Closes #N` (one issue), adds `## Problem / Root Cause`, `## What Changed`, `## Analysis Reference` sections, and extends the checklist with encoding and one-issue-per-PR items.
- **CLI callback consolidation**: Extracted ~125 lines of inline callback definitions (`show_subcommand_help`, `make_subcommand_callback`, `show_compact_help`, `help_callback`, `version_callback`, `_schema_callback`, `_get_hacker_quotes`) from `navig/cli/__init__.py` into canonical `navig/cli/_callbacks.py`. File reduced from 10,062 to 9,938 lines. All existing `from navig.cli import …` imports continue to work via re-export. Fixed `_callbacks.py` to use `Console(legacy_windows=True)` matching original Windows-safe behavior.
- **CLI help registry hotfix**: Restored topic-registry resolution in `navig help` after callback extraction by re-linking `HELP_REGISTRY` in `navig/cli/__init__.py`; this prevents `NameError` failures on `navig help` without a topic.
- **CLI deprecated-wrapper cleanup**: Removed large inline legacy command wrappers from `navig/cli/__init__.py` (`monitor`, `security`, `system`, `hestia`, `template`, `addon`, `workflow`, plus flat legacy aliases). Canonical command groups remain available through external lazy registration (`navig host monitor`, `navig host security`, `navig web hestia`, `navig flow template`, `navig flow`).
- **CLI Dead Code Removal**: Removed 335 lines of dead code from `navig/cli/__init__.py`. The `system_app` and `mcp_app` inline Typer definitions were defined but never registered (superseded by external modules via `_EXTERNAL_CMD_MAP`). File reduced from 10,050 to 9,715 lines. Commands `navig system` and `navig mcp` continue working via their canonical external modules.
- **Telegram unconfigured-AI fallback**: When `on_message` is not set, slash commands (`/help`, `/start`) now receive contextual responses instead of a silent drop or a generic error. Free-text messages still show the "AI not configured" hint.
- **conftest.py basetemp reliability**: `pytest_sessionstart` now resolves the `.local/.pytest_tmp` directory relative to `session.config.rootpath` (falls back to `rootdir`) instead of the CWD, so pytest invocations from subdirectories no longer fail to create the temp dir.
- **Init credential visibility**: `navig init --status` now aggregates AI credential readiness across environment variables, Vault v2 labels, and config keys, and reports detected providers with source hints instead of only a single provider marker.
- **AI provider reconfigure UX**: During `ai-provider` onboarding, provider choices now show `(already configured: env/vault/config)` tags when keys are detected. Pressing Enter on the API key prompt for a detected provider now keeps the existing key and marks the step completed.
- **Telegram NLP aliases routing**: `packages/telegram-bot-navig/plugins/nlp_aliases.py` now routes AI calls through NAVIG core (`run_llm` with fallback to `ask_ai_with_context`) and no longer hardcodes direct OpenAI/OpenRouter HTTP calls or provider-specific models. This aligns plugin behavior with vault/config-managed credentials.
- **Onboarding optional-step status accuracy**: Optional integration steps (`matrix`, `email`, `social-networks`) no longer treat a prior `"skipped"` marker as `completed` when rerun, preventing false-positive completion states in onboarding flow/status summaries (#43).
- **Onboarding rerun UX polish**: `run_engine_onboarding()` now supports `skip_if_configured` so entrypoints can cleanly no-op when `onboarding.json` already exists. `navig init` and first-run startup now use this guard, and the verification dashboard adds a concise `navig init --reconfigure` recommendation when setup finishes with skipped/failed steps.
- **Windows pytest temp-lock hardening**: `tests/conftest.py` no longer uses `tmp_path_factory.mktemp("navig_cfg_isolated")` for the session `NAVIG_CONFIG_DIR` fixture (which can trigger cleanup of stale locked dirs on Windows). It now creates a unique temp directory via `tempfile.mkdtemp`, reducing `WinError 32` fixture explosions after interrupted runs.
- **Init status JSON contract**: `navig --json init --status` now emits pure machine-readable status payload (including readiness issues and next actions) without mixed human-formatted output. `navig --json init` in already-configured state now returns the same payload with `already_configured: true`.
- **Onboarding provider prompt skip-by-Enter**: `ai-provider` and `web-search-provider` setup prompts now default to `"s"` (skip) so pressing Enter skips the step instead of selecting the first provider (#39).
- **Onboarding env-key early import**: `ai-provider` step auto-imports detected environment-variable API keys into vault immediately on selection, so `import-runtime-secrets` (step 16) no longer re-surfaces keys already stored in vault (#41).
- **LocalConnection working_directory + Unicode safety**: `LocalConnection.__init__` now accepts an optional `working_directory` kwarg forwarded as `cwd=` to all subprocess calls, fixing the `TypeError` crash in `navig software` (#60). All `subprocess.run` calls now use `encoding="utf-8", errors="replace"` instead of `text=True`, preventing `UnicodeDecodeError` in the subprocess readerthread on Windows (#48).
- **Onboarding runner UX clarity**: `run_engine_onboarding()` now uses an explicit `skip_if_configured` switch (callers opt in for no-op behavior), removing hidden output suppression for explicit onboarding runs. The verification dashboard also surfaces a single high-signal next action (`navig init --reconfigure`) whenever steps are skipped or failed.
- **Init status actionable guidance**: `navig init --status` now emits a concise `Next actions` block and includes `next_actions` in the returned payload so users can immediately recover from unconfigured states (provider, host, web-search readiness) without guesswork.
- **Init status readiness model**: `navig init --status` now exposes a structured `readiness` object (`state`, `score`, `issues[]`) and prints a compact readiness summary with issue-level commands. This makes status output machine-friendly for UIs and instantly actionable for CLI users.
- **Telegram `/status` readiness parity**: Chat status now includes setup readiness state/score and up to two concrete recovery commands from init readiness diagnostics, aligning Telegram guidance with CLI `navig init --status` output.
- **Telegram `/status` one-tap fixes**: Status cards now include inline `🛠` buttons (`stfix:*`) for the top readiness issues; tapping a button runs the mapped setup recovery command directly through the existing CLI gateway path.
- **Telegram post-fix refresh CTA**: After a one-tap setup fix runs, Telegram now posts a `🔄 Refresh status` button (`nav:open:status`) so users can immediately verify readiness improvements with one tap.
- **Telegram setup-fix dedup guard**: Repeated taps on the same `stfix:*` action are now deduplicated while a fix is running, returning `⏳ Setup fix already running` instead of launching duplicate commands.
- **Telegram `/settings` routing and `/help` formatting fix**: Slash routing now maps `/settings` to the settings hub (`_handle_settings_hub`) instead of the audio panel alias, while `/voice` remains audio-specific. `/help` now renders via deterministic MarkdownV2 command-center output with cleaner sectioning and excludes legacy/admin entries (`/kick`, `/mute`, `/unmute`, `/search`, `/respect`, `/stats_global`) from help text.
- **Telegram MarkdownV2 hardening across interactive flows**: Upgraded key formatted message paths in `telegram_refiner.py`, `telegram_mesh.py`, `telegram_voice.py`, and `telegram_keyboards.py` to `parse_mode="MarkdownV2"` with explicit escaping for user/LLM/provider-derived text in transcripts, Q&A summaries, leader/peer metadata, and audio-file info cards. This prevents raw markdown artifacts and reduces parse failures when content includes special characters.

### Added
- **Coordinator Mode** (FB-01): Added `CoordinatorAgent` plan→execute→synthesise orchestration with worker specs/results, dependency-aware batching, model hint resolution, and synthesis fallback. Added agent tools `coordinator_run` and `coordinator_status`, registered under the `"coordinator"` toolset via `register_all_tools()`. Added regression tests in `tests/test_coordinator.py`.
- **Tavily web search provider**: `navig search --provider tavily` is now a first-class runtime provider alongside Brave and DuckDuckGo. Added `TAVILY_SEARCH_ENDPOINT`, `_search_tavily()` (POST-based JSON API, `max_results` capped at 10), Tavily entries in `_WEB_PROVIDER_ALIASES`, `_WEB_PROVIDER_ENV_VARS` (`TAVILY_API_KEY`), and `_WEB_PROVIDER_VAULT_LABELS` (`web/tavily_api_key`). Runtime dispatch updated. 1 new test in `tests/test_web_search_resolution.py`. Tavily also added to the `navig init` wizard (`_WEB_SEARCH_PROVIDER_CATALOG` + `tavily` alias in `_step_web_search_provider`) so users can configure it interactively (#42).
- **FTS5 Session Search** (F-13): Full-text search for conversation messages using SQLite FTS5 extension. `ConversationStore` schema bumped to v2 with `messages_fts` virtual table (`porter unicode61` tokenizer) and automatic INSERT/UPDATE/DELETE triggers. `fts_search()` method returns BM25-ranked results with score and snippet. `search_content()` upgraded to use FTS5 MATCH with LIKE fallback for robustness. Migration backfills existing messages into FTS index on upgrade. 15 new tests in `test_conversation_store.py`.
- **Worktree Isolation** (FB-05): `WorktreeManager` async git worktree lifecycle manager for parallel agent workers. `Worktree` dataclass tracks name, path, branch, created_at, merged, deleted, `age_seconds` property, and `to_dict()`. `WorktreeManager` supports `create(name, base_branch)` — validates name (alphanumeric/hyphens/underscores), checks `MAX_WORKTREES=10` cap, verifies git repo, creates branch `navig/<name>` and worktree under `.navig_worktrees/`. `merge_back(name, target_branch)` auto-detects HEAD branch when target omitted, checks for new commits via `git log`, attempts `git merge --no-edit`, aborts on conflict and returns False. `remove(name, force)` idempotent removal with Windows retry loop (3×1s), `shutil.rmtree` fallback on exhaustion, `git branch -D` cleanup. `cleanup_all()` removes all worktrees, prunes stale references, removes empty base dir, returns count. `list_worktrees()` returns active (non-deleted) dicts. `get_worktree(name)` returns `Worktree | None` (None for deleted). `active_count` property. Async context manager calls `cleanup_all()` on `__aexit__`. Module-level singleton via `get_manager(repo_root)`/`reset_manager()`. Four agent tools: `worktree_create` (params: name required, base_branch optional), `worktree_list` (no params), `worktree_merge` (params: name required, target_branch optional), `worktree_remove` (params: name required, force optional bool). All registered under `"worktree"` toolset. `.navig_worktrees/` added to `.gitignore`. 86 tests.
- **Background Tasks** (FB-04): `BackgroundTaskManager` async subprocess manager for the agent system. `BackgroundTask` dataclass tracks task_id, label, command, pid, started_at, completed_at, exit_code, output_file, `is_running` property, and `duration` property. Manager supports `start(command, label, cwd)` — spawns a subprocess shell with stdout/stderr captured to disk, returns immediately. `_monitor()` asyncio background task waits for process exit, records exit code, and closes file handles. `status(task_id)` returns dict with running/completed state, duration, exit_code, output line count, and pid. `get_output(task_id, tail=50)` reads last N lines from the output log file. `kill(task_id)` terminates then force-kills after 5s timeout. `list_tasks()` returns status dicts for all tracked tasks sorted by id. `cleanup(max_age=3600)` removes completed task records older than max_age and deletes output log files. `shutdown()` terminates all running tasks and awaits all monitor coroutines for clean teardown (important on Windows). `MAX_CONCURRENT=10` limit enforced at start. Module-level singleton via `get_manager()`/`reset_manager()`. Four agent tools: `background_task_start` (params: command required, label optional, cwd optional), `background_task_status` (params: task_id optional — 0 or omit lists all), `background_task_output` (params: task_id required, tail optional default 50), `background_task_kill` (params: task_id required). All registered under `"background_task"` toolset. Output dir: `~/.navig/bg_tasks/`. Windows-compatible with `encoding="utf-8", errors="replace"` for all file handles. 71 tests.
- **Flow Delegation Test**: `tests/test_flow_delegation.py` with 6 tests verifying `navig flow` correctly delegates to the workflow command group (help, list, subcommand presence, error cases).
- **Memory Auto-Extract** (FB-06): `MemoryAutoExtractor` interval-based scheduler that accumulates conversation turns and triggers batch fact extraction via LLM at configurable intervals. `record_turn(role, content)` buffers user/assistant messages with content truncation (`MAX_TURN_CONTENT_CHARS=2000`) and safety cap (`MAX_PENDING_TURNS=20`). `maybe_extract()` async — fires after every N assistant turns (default `MEMORY_EXTRACTION_INTERVAL=5`), builds a prompt from the last 10 turns, calls LLM, parses JSON response, filters by confidence (`MIN_CONFIDENCE=0.6`), limits to `MAX_FACTS_PER_EXTRACTION=3`, and stores via duck-typed store (`put()` or `upsert()` fallback). `force_extract()` bypasses interval for immediate extraction. `parse_extraction_response()` handles markdown-fenced JSON, regex array search, category validation against 5 categories (preferences/environment/project/relationships/procedures), and confidence clamping. `fact_key()` generates deterministic keys as `category/first_four_words`. `ExtractedFact` and `ExtractionConfig` dataclasses with `from_dict()` classmethod. Silent failure on LLM/store errors — counters always reset in `finally` blocks. Properties: `config`, `turn_count`, `pending_turns`, `total_extracted`, `enabled`. 81 tests.
- **Skills System** (FB-02): `SkillsContext` context-aware skill activation engine for the agent system. Skills are Markdown files with optional YAML frontmatter (`activation_paths`, `activation_keywords`, `priority`) placed in `.navig/skills/` (project) or `~/.navig/skills/` (global). `_parse_skill_file()` loads 3 formats: full frontmatter, partial frontmatter, and plain Markdown (stem becomes name). `_load_frontmatter()` handles missing/malformed YAML gracefully. `ContextSkill` dataclass with name, content, activation_paths, activation_keywords, priority, source (project/global/extra), file_path, and `summary()` helper. `SkillsContext.activate(current_files, user_message)` scores all skills per turn: +10 per glob pattern match (fnmatch against full path AND basename), +5 per keyword in message (case-insensitive), +priority bonus. Auto-loads on first `activate()`. Force-activated skills get score 10000; force-deactivated skills excluded entirely. Sorted by (score, priority, project-before-global), returns top `MAX_ACTIVE_SKILLS` (3). `format_for_system_prompt()` renders `## Active Skills` section with per-skill `### {name}` blocks and `(global)` source tags. `force_activate()`/`force_deactivate()`/`reset_overrides()` for runtime override management. `reload()` re-scans directories. `get_skill()` name lookup. Content truncated at `MAX_SKILL_CHARS` (8000) with marker. Agent tool `manage_skills` with list/activate/deactivate actions via `handle_manage_skills()`. `MANAGE_SKILLS_SCHEMA` OpenAI function-calling format. `register_skill_tools()` integrates with agent tool registry. 68 tests.
- **Telegram Approval Backend** (FA-07): `TelegramApprovalBackend` pluggable backend for `ApprovalGate` that sends approval requests as Telegram inline-keyboard messages ([✅ Approve] [❌ Deny]) and awaits user callback. `ApprovalMessage` dataclass tracks pending requests with request_id, future, message_id, timestamps, and resolution method. `format_approval_message()` renders risk-emoji-annotated Markdown (🟢safe/🟡moderate/🟠dangerous/🔴critical) with tool name, reason, and truncated parameter details. `build_inline_keyboard()` generates Telegram-compatible reply markup with `approval:approve:<id>` / `approval:deny:<id>` callback data. `parse_callback_data()` validates and extracts action+request_id from callbacks. Risk-based timeout policy: safe/moderate auto-approve on timeout, dangerous/critical auto-deny (returns TIMEOUT). Configurable `timeout` (default 120s), `auto_approve_levels`, and pluggable `send_fn`/`edit_fn` transport for bot library integration or built-in HTTP API sender. `handle_callback()` resolves pending futures with double-callback protection. Best-effort message editing on timeout to show resolution. `pending_count` / `get_pending()` for request tracking. 46 tests.
- **Session Transcript** (FA-04): `SessionStore` persistent NDJSON session storage with resume capability. `SessionEntry` dataclass with role, content, timestamp (auto-set), tool_calls, tool_results, compact boundary flag, token/cost tracking, and model identifier. `SessionMetadata` sidecar (`.meta.json`) tracks session_id, turn_count, total_tokens, total_cost, workspace, tags, and finalized flag. Append-only `.jsonl` writes ensure crash safety. `mark_compact_boundary()` records compaction events for `resume()` to start from the most recent snapshot. `resume(max_entries)` loads post-boundary messages in LLM message format, excluding boundary markers. `list_sessions()` returns recent sessions sorted by last_active. `find_by_workspace()` filters by normalized path (case-insensitive). `get_latest()` returns most-recent session optionally scoped by workspace. `cleanup_old_sessions(max_age_days=90)` removes expired sessions. Session ID format `YYYYMMDD_HHMMSS_<4-hex>` for human readability and chronological sorting. 70 tests.
- **Reactive Compaction** (FA-05): `ReactiveCompactor` auto-triggers context compaction at 90% fill, targets 60% after compression. Cache-aware `_find_safe_start()` preserves prompt-cache breakpoints via `has_cache_breakpoint()`. Pluggable `summarizer` callback for testability (sync or async). `_build_digest()` formats conversation chunks for summarisation with per-message truncation and structured-content flattening. Cumulative `stats` property tracks compact count, tokens saved, and estimated cost savings. `should_compact()` threshold check and `compute_target()` budget helper. `get_reactive_compactor()` factory with sensible defaults. Graceful no-op on summarizer failure (returns originals). 56 tests.
- **PlanContext Unified Read Surface** (FA-01c): `PlanContext` dataclass in `navig.plans.context` gives the AI agent complete situational awareness — current phase, dev plan progress, wiki search, project docs, inbox count, and MCP resources — in a single `gather()` call. `format_for_prompt()` renders compact Markdown for system prompt injection. `plans summary` CLI command with cross-space rollup table and `--json` output. `get_plan_context` agent tool registered in `"core"` toolset. Auto-injected into both `conv/agent.py` (lazy `self.context` merge) and `conversational.py` (agentic system prompt section). Project indexer force-includes `.navig/plans/` and `.navig/wiki/` despite `.gitignore` exclusion. MCP `list_resources()` / `list_resources_sync()` added to `MCPClient` and `MCPClientPool`. 23 unit tests for PlanContext, 4 plans summary CLI tests, 4 project indexer force-include tests.
- **Todo Tracker** (FA-03): `TodoList` / `TodoItem` persistent progress tracker for multi-step agent work. `TodoStatus` 3-state enum (not-started / in-progress / completed). Single in-progress constraint prevents parallel work confusion. Verification nudge every 3 completions prompts the agent to validate work. `TodoPersistence` JSONL append-only snapshots with `load_latest()` recovery. `format_display()` emoji-rich rendering (✅🔄⬜). Three agent tools: `todo_create` (JSON array or comma-separated input, replaces existing list), `todo_update` (status transitions with constraint enforcement), `todo_show` (formatted display). 15-item cap, 50-char title limit. Registered in `"todo"` toolset. 57 tests.
- **Plans Reconciliation Engine** (FA-01b): `navig.plans` package — 6-module pipeline for processing `.navig/inbox/` items into canonical `.navig/plans/` structure. `InboxReader` reads exclusively from `.navig/inbox/` with file-suffix lifecycle state (`.md` → `.md.done` / `.md.archive` / `.md.review`). `CurrentPhaseManager` parses and mutates `CURRENT_PHASE.md` with atomic advance, block, and unblock operations. `InboxProcessor` 5-stage reconciliation pipeline (ContentNormaliser → StalenessDetector → DuplicateScanner → ConflictDetector → Router) with JSON Lines staging queue. `ReviewQueue` manages `.md.review` items with commit (re-reconciliation) and archive workflows. `MilestoneProgressEngine` parses checkbox-based progress with visual strip rendering (`✓●⚠○`). `CorpusScanner` extends duplicate/conflict detection across full `tasks/` + `decisions/` corpus. Optional LM spot-checks (duck-typed client, 5s timeout, substring fallback). `scaffold_plans_structure()` creates 8 directories and 5 canonical templates. 60+ tests.
- **Plan Mode** (FA-01): `PlanInterceptor` gates tool access during a structured planning phase — read/search tools allowed, writes blocked with helpful messages. `PlanState` 5-phase lifecycle (INACTIVE → PLANNING → REVIEWING → EXECUTING → COMPLETED). `PlanStep` dataclass with description, tool predictions, affected files, and risk levels. `PlanSession` tracks steps + context gathered during research. Three plan tools (`plan_add_step`, `plan_show`, `plan_approve`) registered in `"plan"` toolset, gated by `check_fn` so they only appear when plan mode is active. `format_plan()` renders Markdown summary. Full cancel/restart support. 58 tests.
- **Effort Levels** (FA-02): `EffortLevel` 5-tier enum (LOW → ULTRATHINK) controlling per-provider thinking budgets. `auto_detect_effort()` heuristic routes simple tasks to LOW (90% cheaper) and complex tasks to HIGH. `get_thinking_params()` generates provider-specific params: Anthropic `thinking.budget_tokens`, OpenAI `reasoning_effort`, Google `thinking_config.budget`, DeepSeek budgets. `resolve_effort()` with 10 aliases (`l`/`lo`/`m`/`med`/`h`/`hi`/`max`/`ultra`/`ut`). Integrated into `run_llm()` pipeline via `effort` parameter + `CompletionRequest.extra_body`. Graceful no-op for unsupported providers. 46 tests.
- **Extended Prompt Cache** (FC-04): `CacheBreakpointPlacer` strategically places up to 4 `cache_control` breakpoints on system prompts, tool definitions, skills context, and conversation prefixes. `CacheStats` tracks hit rates and estimates USD savings (90% discount on cache reads). `has_cache_breakpoint()` utility for compactor integration. New `"strategic"` strategy in `apply_anthropic_cache_control()`. `ExtendedCacheConfig` dataclass with per-layer toggles. 39 tests.
- **Tool Result Caps** (FA-06): `cap_result()` truncates oversized tool outputs at configurable per-tool limits (default 30K chars) with line-boundary snapping and disk spillover to `~/.navig/tmp/tool_spillover/`. Replaces the old 4K backstop in `agent_tool_registry.py` and 8K backstop in `mcp_client.py`. `cleanup_spillover()` removes expired files (1h TTL). Per-tool caps for 12 tools (`bash_exec` 50K, `search` 15K, etc.). 36 tests.
- **Agent Tool Registry** (F-02): `AgentToolRegistry` singleton with `register()`, `dispatch()`, `available_names()`, and OpenAI-schema generation for LLM tool-use APIs.
- **Agent Tool Framework** (F-03): `BaseTool` abstract class and concrete tool implementations — `ReadFileTool`, `WriteFileTool`, `ListFilesTool`, `MemoryReadTool`, `MemoryWriteTool`, `MemoryDeleteTool`, `KBLookupTool`, `WikiSearchTool`, `WikiReadTool`, `WikiWriteTool`. Lazy registration via `register_all_tools()`.
- **Toolset Definitions** (F-04): Named toolset bundles (`core`, `search`, `research`, `code`, `devops`, `memory`, `wiki`, `delegation`, `full`) with `resolve_toolset_names()`, `merge_toolsets()`, `validate_toolset()`, and parallel-safety classification.
- **Agentic ReAct Loop** (F-01/F-05): `ConversationalAgent.run_agentic()` — async multi-turn tool-use loop with parallel/sequential dispatch, context compression, iteration budgets, KB enrichment, and semantic routing.
- **LLM Cost Tracking** (F-06/F-08): `run_llm()` now records token usage. `CostTracker` accumulates `UsageEvent` records per session with `session_cost()` summary. `IterationBudget` guards against runaway loops with shared parent→child counters.
- **MCP Client** (F-09): `MCPClient` and `MCPClientPool` for stdio/HTTP Model Context Protocol servers with tool discovery, `call_tool()`, and connection lifecycle management.
- **Agent Delegation** (F-10): `DelegateTool` enables parent→child agent delegation with `AgentDepthError` guard (max depth 3) and shared iteration budgets.
- **Context Compression** (F-11): `ContextCompressor` with two-pass strategy — cheap token-counting pass + LLM-driven summarization when context exceeds thresholds.
- **Prompt Caching** (F-12): Anthropic prompt cache injection via `apply_anthropic_cache_control()` (`system_and_3` strategy). `supports_caching()` model detection. Optional TTL extension.
- **Approval Gate** (F-14): `ApprovalGate` with pluggable backends, 4-level `ApprovalPolicy` (YOLO/CONFIRM_DESTRUCTIVE/CONFIRM_ALL/OWNER_ONLY), `needs_approval()` predicate, and `NAVIG_ALLOW_ALL_COMMANDS` env bypass.
- **Agent Profiles** (F-15): `Profile` dataclass with isolated `memory_dir`, `wiki_dir`, `config_path`. Resolution via `NAVIG_PROFILE` env → sticky `active_profile` file → `"default"`. CRUD operations: `create_profile()`, `switch_profile()`, `delete_profile()`, `list_profiles()`.
- **DevOps Tool Suite** (F-16): 18 `BaseTool` subclasses wrapping NAVIG CLI operations — host management, remote execution, database ops, Docker management, file operations, web server, app context, and monitoring. All registered under `"devops"` toolset with 6 tools added to `DESTRUCTIVE_TOOLS`.
- **KB Auto-Enrichment** (F-18): Agentic loop detects extractable key facts from assistant responses and stores them in `KeyFactStore` with category tagging.
- **Wiki Tool Integration** (F-19): `WikiSearchTool`, `WikiReadTool`, `WikiWriteTool` enable agent access to project wiki for knowledge retrieval and documentation.
- **Semantic Routing → Toolset Hints** (F-20): `MODE_TOOLSET_HINTS` maps LLM modes to suggested toolsets. `suggest_toolsets()` auto-narrows tool scope based on detected conversation mode. Integrated into `run_agentic()`.
- **Plan-Execute Agent Mode** (F-21): `PlanExecuteAgent` with 4-phase cycle — Plan (LLM JSON plan), Approve (interactive y/N), Execute (sequential dispatch with LLM-driven revision on failure), Report (trace persistence + formatted summary). `format_plan_report()` for human-readable output. Wired via `ConversationalAgent.run_plan_execute()`.
- 101 new tests covering agent modules: toolsets, usage tracker, plan-execute, prompt caching, profiles, approval, semantic routing, and import smoke tests.

### Changed
- **Config Decomposition (PR6/6):** Added `__all__` exports to `navig.core.__init__.py` for clean public API: `HostManager`, `AppManager`, `ContextManager`, `ExecutionSettings`, `atomic_write_yaml`, `log_shadow_anomaly`. Final config.py size: 925 lines (58% reduction from original 2,243 lines). Decomposition complete with full backward compatibility.
- **Config Decomposition (PR5/6):** Extracted `navig.core.execution.ExecutionSettings` class with `get_mode()`, `set_mode()`, `get_confirmation_level()`, `set_confirmation_level()`, `get_settings()` methods. `ConfigManager` now delegates all execution settings via `self._execution`. `config.py` reduced from 991 to 925 lines (66 lines extracted). Project-local override resolution preserved.
- **Config Decomposition (PR4/6):** Extracted `navig.core.context.ContextManager` class with `get_active_host()`, `get_active_app()`, `set_active_host()`, `set_active_app()`, `set_active_app_local()`, `clear_active_app_local()`, `set_active_context()` methods. `ConfigManager` now delegates all context operations via `self._context`. `config.py` reduced from 1,248 to 991 lines (257 lines extracted). Hierarchical context resolution (env → local → legacy → global → default) preserved.
- **Config Decomposition (PR3/6):** Extracted `navig.core.apps.AppManager` class with `exists()`, `list_apps()`, `find_hosts_with_app()`, `load()`, `save()`, `delete()`, `get_file_path()`, `load_from_file()`, `save_to_file()`, `list_from_files()`, `migrate_from_host()` methods. `ConfigManager` now delegates all app operations via `self._apps`. `config.py` reduced from 1,907 to 1,248 lines (659 lines extracted). App caches moved to AppManager.
- **Config Decomposition (PR2/6):** Extracted `navig.core.hosts.HostManager` class with `exists()`, `list_hosts()`, `load()`, `save()`, `delete()` methods. `ConfigManager` now delegates all host operations via `self._hosts`. `config.py` reduced from 2,188 to 1,907 lines (281 lines extracted). Host caches moved to HostManager.
- **Config Decomposition (PR1/6):** Extracted `navig.core.yaml_io` module with `log_shadow_anomaly()` and `atomic_write_yaml()` utilities from `config.py`. Consolidated duplicate `_log_shadow_anomaly()` from `ipc_pipe.py`. `config.py` reduced from 2,243 to 2,188 lines. Backward-compatible aliases preserved.
- CLI root help redesign: `navig --help` / bare `navig` now render a compact grouped command map with a status bar (`host`, `profile`, version), aligned command descriptions, workflow-focused examples, and a rotating one-line tip for quick orientation.
- Added lazy top-level command registrations for `navig logs`, `navig stats`, `navig health`, plus compatibility aliases for common ops nouns: `cert`, `key`, `firewall`, `dns`, `port`, `proxy`, `env`, `secret`, `job`, and `alias`.
- Telegram bot UX: replaced the Main Menu inline keyboard with a conversational context card on `/start`. The card shows active reminder count, current model tier, and a single `[📋 What can I do?]` button that triggers `/helpme` inline — no navigation buttons. All `nav:home` / `nav:cancel` callbacks now send the context card instead of re-rendering the old menu. `/helpme` (`_handle_help`) sends help text directly without going through the navigation stack. The `renderScreen("main")` branch delegates to `_handle_start` for backwards-compatibility with any `nav:home` triggers in settings sub-screens. Navigation stack machinery (`navigateTo`, `navigateBack`, screen_stack) is preserved for settings screen back-navigation only.
- **Telegram command UX overhaul (Phase 4):**
  - `/help` added to the slash-command registry as a visible first-class command (previously only `helpme` was wired and hidden).
  - Fixed 5 silently broken commands: `/think`, `/refine`, `/autoheal`, `/weather`, `/docker`. They now have Python handlers wired via the dynamic registry instead of being dead stubs or incorrect CLI templates. `/think` and `/refine` had their `topic` parameter renamed to `text` for compatibility with the dynamic dispatch mechanism.
- **Telegram command UX overhaul (Phase 5 — heartbeat, status enrichment, mode wiring):**
  - `/ping` is now a rich heartbeat card: shows NAVIG version, active host, active space, model tier, reminder count, and bridge status (with 2 s async timeout). Step-5 dispatch now delegates to `_handle_ping` instead of sending an inline "🏓 pong.".
  - `/status` enriched with active host, active persona, and reminder count. Nav Back/Home buttons removed from standalone `/status` invocations — they only appear when the screen is rendered inside the navigation edit flow (i.e. `message_id` is set).
  - `/mode` wired to the dynamic registry (added `handler="_handle_mode"`). The handler signature was updated from `mode_arg: str` to `text: str = ""` to be compatible with dynamic dispatch. Step-5 also updated to pass `text=cmd`.
  - Registry: `usage=` hints added for `/mode`, `/big`, `/small`, `/coder`, `/restart`, `/tables`, `/plan`.
  - Test: fixed stale `"NAVIG Main Menu"` and `"Canonical onboarding progress"` assertions left over from before the Phase 1 context-card migration. Updated to match current `_handle_start` output.
- **Telegram command UX overhaul (Phase 6 — routing consistency + complete docs):**
  - Added dynamic slash handlers for `/voiceon`, `/voiceoff`, `/trace`, `/restart`, and `/skill` so dynamic dispatch (including `@bot` command forms) behaves consistently with step-5 fast paths.
  - Added/normalized `usage` metadata for argument-bearing Telegram commands: `/auto_start`, `/continue`, `/explain_ai`, `/imagegen`, `/currency`, `/kick`, `/mute`, `/unmute`, `/search`, and `/trace`.
  - Unified menu-era copy to context-card wording in Telegram UI surfaces (`🏠 Home` instead of `🏠 Main Menu` / `🏠 Return to Menu`).
  - Added safe fallback handling for `task:*` callback actions in `telegram_keyboards.py` to prevent callback crashes when task controls are unavailable.
  - Replaced `docs/features/TELEGRAM.md` with a full, registry-aligned Telegram command reference including options, aliases, and inline callback-action families.
  - Updated handbook Telegram section to remove stale Main Menu wording and point to the canonical Telegram command reference.
- **Telegram command UX overhaul (Phase 7 — natural-language command parity):**
  - Added generalized NL-to-command resolver for Telegram so visible slash commands can be triggered via natural language (English-first, deterministic matching).
  - NL execution now routes through existing command handlers/CLI templates instead of duplicating command logic.
  - Added strict confirmation gate for risky NL actions (`/run`, `/restart`, context-mutating operations, moderation commands): users must confirm with `yes`/`cancel` before execution.
  - Added usage-guidance fallback for NL intents that map to commands requiring arguments.
  - Updated Telegram docs to describe NL command parity and confirmation behavior.
  - Added deterministic NL parity coverage tests to keep visible slash commands mapped in NL resolution (`tests/test_telegram_nl_registry_coverage.py`).
- **Telegram command UX overhaul (Phase 8 — command-first suggestions + help polish):**
  - Improved `/help` formatting with a Quick Start section and natural-language examples for faster onboarding.
  - NL command resolver now detects tied top matches and asks users to choose instead of guessing the command.
  - For action-oriented NL requests that don’t map cleanly, Telegram now suggests likely commands (usage-first) instead of silently falling back.
  - Added regression tests for NL suggestion and ambiguity handling in Telegram reminders suite.
  - `/models big|small|coder|auto` — passing a tier name switches immediately (e.g. `/models big` = same as `/big`). Aliases `/model`, `/routing`, `/router` also accept the tier arg.
  - `/providers <name>` — shows a focused card for the named provider with config guidance; falls back to full hub when no arg given.
  - `/spaces <name>` — quick-switches to a space when a name is passed, skipping the list view.
  - `/cancelreminder all` — cancels all active reminders for the user; `/cancelreminder <id>` still works.
  - `/choice` — now accepts `,` and `|` as separators in addition to ` or `; also shows usage when called with no arguments.
  - `/weather [city]` — location-aware weather: `/weather London` fetches weather for that city; plain `/weather` stays serverside.
  - `/docker [ps|logs <name>|restart <name>|stop <name>|start <name>|<container>]` — smart container command dispatch instead of always running `docker ps`.
  - `SlashCommandEntry` dataclass gains a `usage: str` field shown in `/help` output next to the description.
  - `_generate_help_text` overhauled: section headers now include emoji, entries with a `usage` hint display the usage string instead of the bare command name.
  - `_handle_autoheal` parameter renamed `args` → `text` (with `/autoheal` prefix stripping) to work correctly with dynamic dispatch; test suite updated accordingly.
- **Telegram command UX overhaul (Phase 9 — one-tap NL command execution):**
  - NL suggestion and ambiguity cards now include inline one-tap command buttons (`nl_pick:<command>`) so users can run suggested commands directly.
  - `nl_pick` execution follows the same safety policy as typed NL: safe commands run immediately, risky commands open explicit yes/cancel confirmation, and argument-required commands show usage guidance.
  - Added Telegram reminder-suite coverage for suggestion keyboard rendering and `nl_pick` callback behavior (safe, risky, and missing-args paths).
- Release automation: publishing a non-draft/non-prerelease GitHub Release (`v*` tag) now triggers PyPI publication via `.github/workflows/publish.yml` (trusted publishing), with tag-to-`pyproject.toml` version validation and distribution checks.
- CLI UX cleanup: top-level `navig ask` now works as a clean first-class entry point (same behavior as `navig ai ask`) without deprecation noise.
- Ask/Copilot cleanup: removed user-facing "legacy" fallback wording from AI ask path and updated stale `navig ask sessions`/`navig ask ask` examples to canonical `navig copilot ...` forms in interactive/session help text.
- Documentation consistency pass: aligned branch workflow in `CONTRIBUTING.md`, fixed installer script links in `docs/INDEX.md`, and replaced duplicated `docs/README.md` script list with a real docs index.
- Local-only workspace policy clarified: `.dev/` is now the default AI working folder (scripts/logs/outputs), `.local/` is reserved for backups/moved artifacts and compatibility temp files.
- Packaging/publish hardening: removed accidental `CHANGELOG.md` ignore entry, excluded `.dev/` from source distributions, and added root `.dockerignore` exclusions for local/runtime folders.
- Telegram provider picker UX: unconfigured providers now show the key indicator inline with the provider button label (single button), instead of a separate key-only button.
- Local host execution semantics: `navig run` now executes directly on local hosts (`type: local` or `is_local: true`) without SSH/tunnel.
- `navig host test` now performs a local shell probe for local hosts and SSH connectivity for remote hosts.
- CLI routing control: added `navig mode route show` and `navig mode route set <small|big|code> --provider ... --model ...`.
- Local-first host recovery: when no hosts are configured, active host/server recovery now auto-bootstraps `localhost` before falling back to manual host setup prompts.
- Init status view: added `navig init --status` and automatic init status summary when setup is already configured.
- Init quickstart handoff: added `navig init --profile quickstart` (alias to `operator`) with chat-first bootstrap flow, one-time Telegram onboarding baton on `/start`, canonical onboarding checklist/progress in Telegram, explicit success-event step completion (`ai-provider` on provider activation/assignment, `first-host` on successful `host use`, `telegram-bot` on successful runtime auto-start), and automatic daemon+gateway+bot startup attempt when a Telegram token is configured.
- Init web search onboarding: added `web-search-provider` step in engine onboarding with premium provider picker UX (Perplexity/Brave/Gemini/Grok/Kimi), vault-first API-key persistence with compatibility fallback, env alias normalization (`ddg`/`google`/`xai`/`moonshot`) with invalid-value safe fallback to `auto`, `navig init --status` web-search readiness reporting, and `navig search --provider ...` routing wired to runtime provider resolution.
- Proactive/reminder hardening: reminder delivery now uses capped retries (max 3) with failure finalization, engagement cooldown buckets are split (`checkin` vs `idle_nudge` vs `wrapup`), notifier/engine share a process-level engagement coordinator singleton, scheduled task last-run state survives restarts, AI auto-mode sessions expire after 24h inactivity with user-visible notice, and proactive poll intervals are configurable via `proactive.*_interval_sec`.

### Fixed
- **Migration ANSI color fix**: Removed module-level `Console(stderr=True)` from `navig/core/migrations.py` that broke Windows VT processing for all subsequent stdout output. Migration log messages now route through the centralized `console_helper` singleton (#38).
- **Vault state sync**: `navig config set <sensitive-key>` now performs a best-effort write-through to the CredentialsVault for 14 known AI/integration API keys (OpenAI, Anthropic, Groq, Google, NVIDIA, xAI, Mistral, OpenRouter, GitHub Models, Telegram), so `navig vault list` reflects the key immediately without a separate `vault set` step. `navig vault list` also now shows a "Credentials detected outside vault" footer for AI provider keys found in environment variables or config but not yet synced to the vault, with a one-liner sync hint (#62).
- **Modular identity — IDENTITY.md Phase 1 (RFC #37)**: `soul_loader.py` now recognises `~/.navig/workspace/IDENTITY.md` as step 3 in the 6-level priority chain (between active-space SOUL.md and the legacy workspace SOUL.md). When present, `IDENTITY.md` is used as the agent's runtime identity without requiring the full `SOUL.md` monolith. Existing installations that only have `SOUL.md` are unaffected. Playbook lazy-loading and `GUARDRAILS.md` splitting are deferred to Phase 2 (#37).

## [2.4.20] - 2026-03-31

### Added
- **`navig vault` command group** — new top-level `vault` command with `set`, `get`, `list`,
  `validate`, and `delete` subcommands. Smart path parsing supports `provider/key` paths,
  bare provider names, and `provider_api_key` env-var style aliases.
  Example: `navig vault set nvidia/api_key nvapi-xxxx`
- **Multilingual agent support** — `ConversationalAgent` now pins per-user language overrides
  in `KeyFactStore`; fact extractor rewrites facts to English before storage; `FactRetriever`
  infers user language and formats responses accordingly.
- **Messaging registry provider validation** — `MessagingRegistry` exposes provider
  validation and retrieval helpers used by gateway channel routing.
- **New test suites** — `test_conversational_language_policy`, `test_channel_router_auto_persona`,
  `test_telegram_auto_runtime`, `test_key_facts`, `test_context_builder`,
  `test_telegram_provider_callbacks`, `test_messaging_registry`.

### Fixed
- **Windows test stability** — `tests/conftest.py` now performs pre-cleanup of stale `navig_cfg_isolated*` temp directories before session start, preventing `PermissionError` on Windows when SQLite vault files remain locked from crashed test runs. Also adds post-session vault connection cleanup.
- **`navig vault` was missing** — `navig vault set` returned `No such command 'vault'` because
  `vault_app` was not registered in `_EXTERNAL_CMD_MAP`.
- **`navig init` crash** on packages missing `_maybe_send_first_run_ping` — now catches
  `AttributeError` alongside `ImportError`.
- **Task Scheduler `Access Denied`** — `service_manager.py` now detects the error and prints
  a clear "run as administrator" instruction instead of a raw traceback.

### Added
- **`navig --schema` now works** — `navig/cli/registry.py` was missing, causing an `ImportError`
  whenever `navig --schema` or `navig help --schema` was called. The module is now created and
  returns a stable JSON document listing every command group and its subcommands.
- **`docs/user/workflows.md`** — New common-workflows guide covering database backup, deploy flows,
  bulk file transfer, server health checks, Telegram bot setup, database restore, and SSH key rotation.
- **HANDBOOK.md section 1.7 — In-App Help System** — Documents `navig help`, `navig help <topic>`,
  and `navig --schema` so users and AI agents know how to get help without leaving the terminal.
- **`docs/upgrade-roadmap.md`** — Prioritised roadmap of planned features, deprecation timeline
  (v3.0 sunset), implementation task checklist, and migration guide.

### Fixed
- **`docs/user/commands.md`** — Replaced stale references to deprecated `navig monitor` and
  `navig security` top-level commands with the canonical `navig host monitor show` and
  `navig host security show` forms. Updated tunnel commands (`start/stop/status/restart` →
  `run/remove/show/update`), file operations (`upload/download/cat/ls` → `navig file add/get/show/list`),
  and HestiaCP commands (`navig hestia` → `navig web hestia`).
- **`docs/user/quick-start.md`** — Replaced `python navig.py --version` with `navig --version`
  throughout. Updated install instructions to reflect `pip install navig` and `pip install -e .`.
  Fixed deprecated `navig monitor disk/health/resources` references to `navig host monitor show`.
  Fixed deprecated `navig tunnel start` to `navig tunnel run` and file command aliases.

### Fixed

- **Daemon: Telegram bot infinite restart loop** — Supervisor now stops retrying after
  15 consecutive quick exits (<30 s). Prevents 2 000+ restart cycles when a second bot
  instance on the same token causes a Telegram `Conflict` error. (`daemon/supervisor.py`)
- **MCP Forge unavailable on startup** — `MCPClientManager.add_client()` now receives an
  `MCPClientConfig` object instead of stale `name=`/`url=` keyword arguments that broke
  the Forge connection every time the daemon started. (`daemon/telegram_worker.py`)
- **`navig formation show --json` crashes on Windows** — `print()` raised
  `OSError: [Errno 22] Invalid argument` on non-TTY stdout (VS Code terminal). Fixed by
  switching to `click.echo()`. (`commands/formation.py`)
- **Voice setup instructions pointed to removed file** — STT warning now says
  `run 'navig init'` instead of referencing the deleted `~/.navig/.env` path.
  (`daemon/telegram_worker.py`)
- **GROK/XAI API key bypassed vault** — GROK key check now uses the vault resolver before
  falling back to environment variables, consistent with all other provider keys.
  (`daemon/telegram_worker.py`)

### Fixed — Help system

- **`navig help <topic>` silently returned empty results** — `help_command` looked in
  `navig/cli/help/` (wrong) instead of `navig/help/` (correct). All topic files now resolve
  correctly. (`cli/__init__.py`)
- **`navig --help` and bare `navig` printed bare fallback instead of index** — Both
  `show_compact_help` implementations imported a non-existent `navig.cli.help.render_root_help`
  module. Now read `navig/help/index.md` directly via Rich Markdown. (`cli/__init__.py`,
  `cli/_callbacks.py`)
- **`navig help <topic> --json` output contained unescaped newlines** — Rich Console
  line-wrapping was inserting unescaped `\n` into JSON string values. All JSON output in
  `help_command` now uses `typer.echo()` which bypasses Rich's formatter. (`cli/__init__.py`)
- **`task` help described a non-existent task queue** — `navig/help/task.md`,
  `navig/help/index.md`, and `HELP_REGISTRY["task"]` now correctly document `task` as a
  backward-compatible alias for `navig flow`. (`cli/help_dictionaries.py`, `help/task.md`,
  `help/index.md`, `help/flow.md`)

### Tests

- Added `tests/test_help_system.py` — 20 smoke tests covering help topic resolution,
  JSON output validity, `task`/`flow` alias documentation, missing-topic error handling,
  and markdown directory path correctness.

### Docs

- `docs/user/troubleshooting.md` — Added *Recently Fixed Issues (v2.4.15+)* section
  covering all five daemon/CLI bugs listed above.
- `docs/upgrade-roadmap.md` (new) — Prioritized implementation task list derived from the
  March 2026 crash-log and codebase audit.

## [2.4.13] - 2026-03-12

### Security / Portability — Cross-Platform Audit (`upgrade/portability-audit`)
- **`navig/daemon/service_manager.py`** — `import ctypes` moved inside the `try` block of `is_admin()` to fix `NameError` on Windows (was crashing daemon startup).
- **`navig/commands/security.py`** — All 31 callsites replaced `result['exit_code']` / `result['stdout']` / `result['stderr']` dict access with `.returncode` / `.stdout` / `.stderr` attributes on `subprocess.CompletedProcess`; entire security subsystem was broken (TypeError on every call).
- **`navig/remote.py`** — Localhost-shortcut path now uses `shell=False` + `shlex.split()` instead of `shell=True`; added Windows Unix-tool guard (`NotImplementedError` for `ls`, `df`, `cat`, etc.).
- **`navig/agent/service.py`** — `_install_systemd()` guarded by `sys.platform`: Linux → `/etc/systemd/system`, macOS → `~/Library/LaunchAgents`, Windows → `~/navig-services` + `schtasks`, other platforms → graceful failure. Previously unconditionally wrote to `/etc/systemd/system` on all platforms.
- **`navig/core/automation_engine.py`** — `run_command` action: `shell=True` → `shell=False` + `shlex.split()` + RCE denylist.
- **`navig/agent/conversational.py`** — Both `command.run` and `navig.run` actions: `shell=True` → `shell=False` + `shlex.split()` + denylist.
- **`navig/discovery.py`** — `_build_ssh_command()`: `StrictHostKeyChecking=no` + `UserKnownHostsFile=/dev/null` → `accept-new`; insecure mode gated behind `self.insecure`. Fixed `HAS_PARAMIKO = True` hardcode — now a runtime try/import check.
- **`navig/commands/sync.py`** — rsync `-e` option: `StrictHostKeyChecking=no` → `accept-new`; `shlex.quote()` wrapping on `ssh_key` path.
- **`navig/agent/runner.py`** — Added Windows signal handler fallback: `signal.SIGBREAK` + `signal.SIGINT` via `signal.signal()` (Windows has no `loop.add_signal_handler()`).
- **`navig/commands/backup.py`** — `os.chmod(config_path, 0o600)` wrapped in `try/except OSError`; added Windows `icacls` ACL fallback.
- **`navig/logging_setup.py`** — `_NAVIG_DIR` / `_LOG_DIR` / `_LOG_FILE` / `_DEBUG_FLAG` now resolve from `NAVIG_CONFIG_DIR` environment variable before falling back to `~/.navig`.
- **`navig/ipc_pipe.py`** — Unix socket path uses `tempfile.gettempdir()` instead of `/tmp` (breaks under macOS App Sandbox); `conn._handle.SetReadTimeout(...)` wrapped in `try/except AttributeError`.
- **`navig/adapters/os/linux.py`** — Package manager detection uses `shutil.which(pm)` instead of `os.path.exists('/usr/bin/{pm}')` to respect `$PATH`.
- **`navig/commands/docker.py`** — Unsanitised `| grep -E '{filter}'` injection fixed with `shlex.quote(filter)`.
- **`navig/tunnel.py`** — Removed `-f` SSH background-fork flag; `process.pid` stored directly instead of psutil polling (eliminates PID reuse race); reduced `time.sleep(2)` → `time.sleep(0.5)`.
- **`navig/vault/encryption.py`** + **`navig/vault/storage.py`** — Added Windows `icacls` ACL restriction after `os.chmod` for vault and salt files.
- **`navig/commands/monitoring.py`** — CPU batch command replaced fragile `top -bn1 | grep 'Cpu(s)'` (breaks on RHEL/CentOS) with portable `/proc/stat` awk calculation.
- **`navig/commands/files.py`** — Disk-space error hint is platform-conditional: `df -h` on Unix, `Get-PSDrive` / `dir /-c` on Windows.
- **`navig/plugins/navig-mini/plugin.py`** — Default `--dir` option changed from `/root/navig-mini` to `~/navig-mini` (non-root-user portability).
- **Encoding sweep (13 files)** — Added `encoding='utf-8'` to all `open()` / `Path.read_text()` calls in: `tunnel.py`, `mcp_manager.py`, `commands/proactive.py`, `commands/script.py`, `commands/suggest.py`, `commands/local.py`, `commands/triggers.py`, `assistant_utils.py`, `tasks/queue.py`, `memory/embeddings.py`, `vault/core.py`, `local_operations.py`, `commands/monitoring.py`.
- **Documentation updates** — Updated 5 docs to reflect `NAVIG_CONFIG_DIR` portability:
  - `README.md` — Config location note updated; config tree annotated with `← default; override with NAVIG_CONFIG_DIR`.
  - `docs/user/troubleshooting.md` — Debug log path mentions `$NAVIG_CONFIG_DIR/debug.log` fallback.
  - `docs/user/HANDBOOK.md` — CI/CD env-var table gains `NAVIG_CONFIG_DIR` row (override config/log base directory).
  - `docs/architecture/AUTONOMOUS_DEPLOYMENT.md` — Dockerfile and docker-compose examples migrated from `/root/.navig` to `/app/.navig` with `ENV NAVIG_CONFIG_DIR=/app/.navig` (non-root container portability).
  - `docs/dev/PRODUCTION_DEPLOYMENT.md` — `docker run` mounts updated to `/app/.navig` with `-e NAVIG_CONFIG_DIR=/app/.navig`.

### Security / Portability — Cross-Platform Audit Round 2 (`upgrade/portability-audit`, 2026-03-01)
- **`navig/commands/sync.py`** (`_run_pull`) — `StrictHostKeyChecking=no` → `accept-new`; `ssh_key` path now wrapped with `shlex.quote(str(...))`. Mirrors the `_run_push` fix applied in Round 1 — the pull-side was inadvertently missed. [R1 — Critical regression]
- **`navig/commands/security.py`** (`firewall_allow`) — `allow_from`, `port`, `protocol` now wrapped with `shlex.quote(str(...))` before interpolation into the UFW SSH command. Previously allowed remote command injection via any of those three user-supplied arguments. [C1 — Critical]
- **`navig/commands/security.py`** (`fail2ban_unban`) — `jail` and `ip_address` now wrapped with `shlex.quote()` in both `fail2ban-client set … unbanip` and `fail2ban-client unban` commands. [C2 — Critical]; `import shlex` added to module imports.
- **`navig/core/automation_engine.py`** (`run_command`) — Denylist check now normalises the command string via `unicodedata.normalize('NFKC')` + `re.sub(r'\\s+', ' ')` + `.lower()` before matching, blocking bypass via uppercase (`RM -RF`), double-space, tab, or Unicode look-alikes. `shlex.split()` call now passes `posix=(sys.platform != 'win32')` to preserve Windows backslash paths. [C3 + L2]
- **`navig/core/evolution/fix.py`** (`CodeFixer.validate`) — `subprocess.run(cmd, shell=True)` replaced with `shlex.split(cmd, posix=…) + shell=False` for config-sourced `check_command` strings. [M1]
- **`navig/commands/packs.py`** / **`navig/commands/skills.py`** — Added explicit trust-boundary comments on `shell=True` subprocess calls for pack/skill hook commands (intentional — author-defined scripts may use pipelines). [M2, M3]
- **`navig/commands/database.py`** (`_create_mysql_config_file`) — `os.chmod(0o600)` now guarded by `sys.platform` check with `icacls` fallback on Windows, matching the identical fix already applied to `commands/backup.py`. `import sys` added. [M4]
- **`navig/commands/backup.py`** — `encoding='utf-8'` added to all six bare `open()` / `os.fdopen()` write calls (`_create_mysql_config_file`, three `metadata.json` writes, MySQL dump header, HestiaCP metadata, web-server metadata). [M5–M8 + 2 additional sites]
- **`navig/commands/agent.py`** — `encoding='utf-8'` added to all bare `open()` calls (config read/write ×4, log read, personality write) and two `write_text()` calls (systemd temp file, macOS plist). [M9]
- **`navig/commands/assistant.py`** — `encoding='utf-8'` added to all bare `open()` calls (history read, issues read ×2, context JSON write, reset-data write). [M10]
- **`navig/adapters/os/linux.py`** (`LinuxAdapter`) — `get_temp_directory()` fallback changed from hardcoded `'/tmp'` to `tempfile.gettempdir()`; `get_home_directory()` fallback changed from `'/root'` (fails for non-root container users) to `Path.home()`. [M11]
- **`navig/daemon/service_manager.py`** (`_schtasks_xml`) — Task Scheduler XML now escapes `python` executable path and `args` string via `xml.sax.saxutils.escape()` (stdlib, no new dependency) before interpolation. Paths containing `&`, `<`, or `>` previously produced malformed XML. [M12]
- **`navig/commands/bridge_ai.py`** (`bridge_stop`) — `os.kill(pid, SIGTERM)` now guarded by `sys.platform != 'win32'`; Windows branch uses `subprocess.run(["taskkill", "/PID", str(pid)])` for catchable graceful shutdown instead of `TerminateProcess`. [L1]
- **`navig/agent/service.py`** (`_install_systemd`) — `service_path.write_text(unit_content)` now passes `encoding='utf-8'` explicitly. [L3]

> Test results after Round 2: **3058 passed** (+7 vs Round 1 baseline), **53 skipped**, **1 pre-existing flaky failure** (`test_decoy_guard::test_different_messages_different_output` — randomness-based assertion, unrelated to audit changes). All 3 previously listed pre-existing failures are now resolved.

### Performance — Phase 3 Startup & Syscall Reduction (`upgrade/portability-audit`, 2026-02-28)
- **`navig/config.py`** (`_is_directory_accessible`) — `list(iterdir())` → `next(iterdir(), None)`: O(N) → O(1) directory-access probe.
- **`navig/config.py`** (`_ensure_directories`) — stamp-file gate (`~/.navig/.dirs_init`, 24h TTL): 40+ `mkdir` syscalls → single `stat` on warm runs every process invocation after the first.
- **`navig/config.py`** (`_load_global_config_cached`) — shadow-verify thread now rate-limited: skips spawn if `time.monotonic() - _last_shadow_ts < 300`; at most one background thread per 5 minutes.
- **`navig/config.py`** (`_find_app_root`) — sentinel-based process-lifetime cache (`_APP_ROOT_NOT_SEARCHED`): CWD filesystem walk runs once per process, not per call.
- **`navig/config.py`** (`get_active_host`) — `_active_host_cache` tuple: YAML parse on first call only; `set_active_host` invalidates. New `_resolve_active_host()` private helper.
- **`navig/config.py`** (`list_hosts`) — dir-mtime pre-check guards the per-file stat scan; returns cached list immediately when directory mtime unchanged.
- **`navig/config.py`** (`list_apps`) — `_apps_list_cache` was initialised in `__init__` but never used; now wired with mtime-keyed per-host invalidation.
- **`navig/config.py`** (`_host_config_cache`) — capped at 64 entries via new `_host_cache_put()` LRU helper; prevents unbounded dict growth in multi-host environments.
- **`navig/plugins/__init__.py`** — module-level `Console()` eager import replaced with lazy `_get_console()` factory; `rich.console` only imported when a plugin actually prints output.
- **`navig/cli/__init__.py`** (`_EXTERNAL_CMD_MAP`) — 10 commands added: `telemetry`, `wut`, `eval`, `agents`, `webdash`, `explain`, `snapshot`, `replay`, `cloud`, `benchmark`; all now fully lazy-dispatched.
- **`navig/main.py`** — 11 unconditional `try/except` import blocks removed (replaced by `_EXTERNAL_CMD_MAP` entries); eliminates 11 module imports on every startup.
- **`navig/remote.py`** — `SSHConnectionPool` fast-path added for `capture_output=True` SSH calls; reuses pre-existing pooled paramiko connections from `connection_pool.py` (which was dead code); subprocess fallback retained for PTY/non-captured paths.

> Full analysis: `docs/CLI_STARTUP_PERFORMANCE.md` § Phase 3. Zero regressions (2939 passed, 53 skipped).

### Changed — OSS Release Audit (MVP1 gate)
- **`navig/integrations/telegram_bridge.py`** — added `_scrub_token()` helper;
  `logger.warning` in the long-poll exception handler now redacts the bot token
  from httpx URL reprs before they reach any log output (`.cursorrules` rule #6:
  secrets never in logs, even under `--debug`).
- **`navig/integrations/telegram_inbox.py`** — `_get_file_bytes` now raises
  `RuntimeError` when Telegram returns `ok=false` (e.g. 401 Unauthorized,
  revoked bot token); `_handle_message` catches and logs without crashing;
  `run()` uses `upd.get("update_id")` defensively to skip malformed updates.
- **`navig/commands/memory.py`, `navig/commands/kg.py`, `navig/commands/store.py`**
  — added `# CURSORRULES:R8-EXCEPTION:` annotations explaining why each
  diagnostic read-only `sqlite3` call is justified and cannot use
  `storage/engine.py` (`.cursorrules` rule #8 explicit documented exception).
- **`navig/commands/spaces.py`** — **name history**: this file was originally
  created as `spaces.py` to provide a "spaces" concept distinct from `space.py`
  (which manages full space directories).  During the active_space_context
  refactor the command was renamed to `spaces` internally; the file was kept as
  `spaces.py` for backward-compat imports.  The public CLI surface is
  `navig spaces list/show/switch`; the `spaces_app` alias exists only for
  internal imports.  The command does **not** implement `@target` routing
  (agents/workspaces/people) — that is a separate post-MVP2 feature tracked
  in `.navig/plans/TASK_PROPOSALS.md`; see `# KNOWN GAP:` comments in the file.

### Fixed — Security / Test Coverage
- Added 4 failure-path tests to `tests/test_telegram_inbox.py`
  (tests 12–15): Telegram API 401 rejection, download failure swallowed,
  bad-token run() does not crash, malformed update skipped.

### Added — Package Manager + Cross-Platform Architecture Sprint

#### Cross-Platform Path Infrastructure
- `navig/config.py` — `roaming_root` (AppData\\Roaming\\NAVIG on Windows, `~/.config/NAVIG` on Linux/macOS), `identity_dir`, `store_dir`, `system_dir`, `logs_dir`, `cache_dir` — all via `platformdirs`; removed hardcoded `~/.navig` references
- `navig/daemon/entry.py` — `_navig_home()` lazy helper; auto-starts WebSocket server in `main()`
- `navig/daemon/service_manager.py` — full **macOS launchd** backend: `launchd_install/uninstall/status`; plist written to `~/Library/LaunchAgents/run.navig.NavigDaemon.plist`; `detect_best_method()` returns `"launchd"` on darwin
- `navig/commands/service.py` — log path resolved via `ConfigManager().logs_dir`
- `pyproject.toml` — `platformdirs>=4.0.0` dependency added

#### New CLI Commands
- `navig user` — user profile management (`show/set/switch`)
- `navig node` — multi-node discovery and management UI
- `navig boot` — boot sequence configuration
- `navig space` — space/environment management (dev/staging/prod)
- `navig blueprint` — project blueprint scaffold and template definitions
- `navig deck` — deck/stack management UI
- `navig portable` — portable mode for USB/external drive launch
- `navig install` (v2) — package installer with SHA-256 cache, `--update`, `--freeze`
- `navig migrate run/status/rollback` — migrate `~/.navig` → platform roaming dir; compat symjunction so old paths keep working
- `navig system init/wallpaper/icons/theme/sounds` — OS integration in `portable`/`standard`/`deep` modes; cross-platform (Win32 API + gsettings/GTK)
- `navig paths` — show all resolved NAVIG directories with ✅/❌ status + daemon WS reachability; `--json`
- `navig mcp install/uninstall/status/serve` — wires `.vscode/mcp.json` and VS Code user settings for the NAVIG MCP server

#### Daemon WebSocket Server
- `navig/daemon/ws_server.py` — JSON-RPC 2.0 WebSocket server (`ws://127.0.0.1:7001/ws`) with `exec` (subprocess streaming), `status` (daemon health), `cancel` (kill in-flight proc), `start_ws_server()` background thread launcher

## [2.3.0] — 2026-02-25 — First Public Open-Source Release

> First public release on GitHub under Apache-2.0. All internal identifiers,
> personal paths, and private server references scrubbed. Repository renamed
> to `navig-run/core`.

### Workspace
- **Rename NAVIG Bar → NAVIG Dock** (no functional changes) — `@navig/bar` v0.1.0 → `@navig/dock` v0.1.1
  - Folder `navig-bar/` → `navig-dock/`; package name `@navig/bar` → `@navig/dock`
  - All internal imports, DOM IDs, manifest command keys, and build artifact names updated
  - Root `package.json` scripts updated (`dev:bar` → `dev:dock`, etc.)
  - `pnpm-workspace.yaml` deduped: single `navig-dock` entry, `navig-bar` removed
  - See [`navig-dock/docs/audit.md`](../navig-dock/docs/audit.md) and [`navig-dock/docs/README.md`](../navig-dock/docs/README.md)

### Open-Source Readiness
- Switched license posture to **Apache-2.0** for ecosystem and enterprise adoption.
- Raised Python support floor to **3.10+** and aligned packaging metadata.
- Added GitHub Actions workflows for CI, CodeQL, and release provenance attestation.
- Added repository community scaffolding:
  - `CONTRIBUTING.md`
  - `CODE_OF_CONDUCT.md`
  - issue templates and PR template
  - `.editorconfig`
- Enforced coverage gate (`--cov-fail-under=65`) for release readiness.
- Updated governance/security/release policy docs for OSS publication.

### Added
- **Flux Mesh — LAN-local multi-node discovery** (`navig/mesh/`):
  - `NodeRegistry` — singleton peer store with health states (`online` / `degraded` / `offline`) and automatic eviction after 30 min of silence.
  - `MeshDiscovery` — async UDP multicast broadcaster/listener on `224.0.0.251:5354`. Sends HELLO on startup, heartbeats every 30 s, GOODBYE on shutdown.
  - `router.py` — HTTP proxy that forwards requests to the best available peer (lowest load) with `mesh_token` auth and 10 s timeout.
  - Gateway routes: `GET /mesh/peers`, `POST /mesh/ping`, `POST /mesh/route` — registered automatically via `register_all_routes()`.
  - `_ensure_mesh_token()` — auto-generates `secrets.token_hex(32)` on first gateway start; persists to `~/.navig/config.yaml`.
  - **`navig flux` CLI command group** (`navig/commands/flux.py`): `status`, `peers`, `ping <url>`, `route <message>` (also accessible as `navig fx`).
  - **BackendRegistry priority chain** rewritten: local daemon → best mesh peer → Copilot (last).
  - **VS Code Bridge nodes panel** (`navig.nodesPanel`): live peer tree with health icons, set/clear target, add node, scan LAN commands.
  - 11 unit tests (`tests/mesh/test_registry.py`) — all passing.
  - Feature doc: `docs/features/flux-mesh.md`.

- **Multi-channel architecture design** — `.navig/plans/CHANNEL_ARCHITECTURE.md` with ChannelAdapter base class, ChannelRouter, ChannelCapabilities, config schema, security rules per channel, and phased implementation plan (Telegram, Discord, Web UI, CLI, Email).
- **Conversational pre-filter** in intent parser — Detects greetings, identity questions, general questions, and casual chat; routes them directly to AI instead of NLP command matching.

### Improved
- **Bot consciousness** — The Telegram bot now responds conversationally instead of robotically:
  - System prompt injects SOUL.md personality (Deepwatch Abysswarden identity).
  - Identity questions (who are you, what's your name) go through AI for dynamic, context-aware responses instead of hardcoded `SOUL_RESPONSES` strings.
  - `_generate_contextual_response()` used for all personality questions, with static SOUL_RESPONSES as fallback.
- **NLP time regex fix** — "what time is it?" no longer produces `/time IS`. Replaced single greedy regex with specific patterns: "time is it in \<tz\>", "time in \<tz\>", "time is it", "current time".
- **dev.instructions.md** — Now references `~/.navig/workspace/` (SOUL.md, IDENTITY.md, AGENTS.md, USER.md) and `.navig/plans/` (DEV_PLAN.md, ROADMAP.md, VISION.md, SPEC.md).

### Fixed
- **Intent parser false positives** — Conversational messages ("hello", "how are you", "what is the meaning of life?") no longer get intercepted as commands.

- **System tray overhaul** — Complete rewrite of the tray menu:
  - **Dynamic menu** — Menu rebuilds on every right-click, reflecting live service states (running/stopped/grayed out).
  - **Rich command groups** — Hosts, Database, Vault, Skills, Backups sub-menus with interactive terminals that stay open after output.
  - **Autostart with Windows fixed** — Registry read/write now uses correct `winreg.OpenKey`/`CreateKeyEx` API (was using non-existent `OpenSubKey`).
  - **Interactive commands** — Quick action commands now open `cmd /k` terminals that remain open so you can read the output.
  - **Settings sub-menu** — Toggle auto-start tray with Windows, toggle auto-start bot on tray launch, open config/log folders.
  - **Advanced sub-menu** — Standalone Gateway/Agent start/stop (grayed when not applicable), service status, daemon logs, NAVIG Terminal.
  - **"Open NAVIG Terminal"** — Opens a cmd prompt pre-configured for navig commands.

## [3.23.0] — Persistent Daemon + Service Management

### Added
- **NAVIG Daemon** (`navig/daemon/`) — New process supervisor that keeps the Telegram bot (and optionally gateway, scheduler) running permanently with auto-restart on crash, exponential back-off, PID tracking, and structured log rotation.
- **`navig service install`** — One-command service installation. Auto-detects the best method:
  - **NSSM** (if installed + admin) — true Windows service, starts on boot
  - **Task Scheduler** (no admin needed) — starts on login, auto-restarts on failure
- **`navig service start/stop/restart`** — Full lifecycle management of the daemon process.
- **`navig service status`** — Shows daemon PID, child process health, restart counts, and service registration status.
- **`navig service logs`** — Tail daemon logs with `--follow` support; logs rotate at 5 MB.
- **`navig service config`** — View/edit daemon configuration (`~/.navig/daemon/config.json`): toggle bot/gateway/scheduler, health-check port.
- **`navig service uninstall`** — Clean removal of service registration and daemon.
- **Health-check TCP endpoint** — Optional HTTP health-check server (for monitoring tools) returns JSON status of all child processes.
- **Hybrid agent profiles** — Formation agents now support directory-based profiles (`agents/<id>/` with `SOUL.md`, `PERSONALITY.md`, `PLAYBOOK.md`, `MEMORY.md`, `agent.json`). System prompt composed from markdown docs at load time. Backward compatible with flat `.agent.json` format.
- **System tray daemon control** — Tray app (`scripts/navig_tray.py`) now manages the daemon: start/stop Telegram Bot from tray menu, live status display, auto-start on launch, health monitoring with external daemon detection.

### Fixed
- **Bot crash on startup** — `TypeError: AsyncClient.__init__() got an unexpected keyword argument 'proxies'` caused by httpx 0.28+ removing the `proxies` parameter. Pinned httpx to `>=0.27,<0.28` which satisfies both python-telegram-bot and mcp/ollama.
- **Duplicate log lines** — Every daemon child log line appeared twice due to PIPE+merge. Supervisor now redirects stdout/stderr directly to log files.
- **Visible CMD window** — Daemon started in a visible console. Now uses `pythonw.exe` + `CREATE_NO_WINDOW` flag + Task Scheduler `<Hidden>true</Hidden>` for fully invisible background operation.
- **YAML parse errors** — Unquoted colons in `description` fields of `github/SKILL.md` and `postgres/SKILL.md` caused YAML parse failures.
- **Windows `navig agent service install` only printed instructions** — Now delegates to the real daemon service manager for actual NSSM/Task Scheduler installation.

### Changed
- **Agent schema relaxed** — `AGENT_SCHEMA` required fields reduced from 7 to 3 (`id`, `name`, `role`) to support lightweight directory-based profiles.

## [3.22.0] — Telegram Heartbeat + Council Overhaul

### Added
- **Heartbeat system** — VS Code extension writes `~/.navig/heartbeat.json` every 30s while a formation is active (formation ID, agents, workspace, timestamp). Cleared on stop/deactivate.
- **Proactive Telegram messages** — Bot checks for actionable items (urgent markers, failing tests, inbox briefs, next-step files, TODOs in `.navig/plans/`) and sends at most **one short message per heartbeat window** (default 5 min). Completely silent when VS Code is idle or closed.
- **`/formation` command** — Check current VS Code formation status on demand (active/stale/offline, agents, workspace, next action).
- **Formation context injection** — When you message the bot directly, it includes lightweight formation state so the AI can reference your active work without you having to explain.
- **Core NAVIG Telegram persona** — Bot operates as "Core NAVIG" on Telegram: calm, fast, direct. Can reference multiple formations, answer general questions, suggest which project deserves attention.
- **Urgency-aware action scanner** — Proactive messages now check (in priority order): `urgent.md`, `failing-tests.md`, inbox briefs, `next-step.md`, `todo.md`.
- **Heartbeat configuration** — New env vars: `HEARTBEAT_ENABLED` (true/false), `HEARTBEAT_INTERVAL` (seconds between checks, default 60), `HEARTBEAT_WINDOW` (min seconds between proactive messages, default 300).
- **Council compact view** — New Full/Compact toggle in Council Panel header. Compact mode truncates agent messages to 2 lines with click-to-expand, smaller text, and tighter spacing for scanning long deliberations.

### Fixed
- **Council agents all said the same thing** — Agents now receive their specific `scope` areas in the prompt and are told which other roles will cover other angles. Each agent answers from their unique perspective: architect on trade-offs, devops on ops overhead, QA on test complexity, security on attack surface, product on user impact.
- **Council was too slow** — Agents now run **in parallel** within each round (was sequential). 5-agent round completes in ~10-15s instead of ~45-50s (3-4x faster).
- **Thread-safe AI imports** — Moved `ask_ai_with_context` import to module level to prevent race conditions when 5 agents import simultaneously in parallel threads.

### Improved
- **Council synthesis** — Final decision prompt now highlights where agents **agreed** and **disagreed**, with a concrete next step, instead of a bland summary.

### Changed
- **SOUL.md** — Added Telegram & External Channel Behavior section defining Core NAVIG personality rules for paired channels.

## [3.21.0] — Schema Fix + Agent Personalities

### Fixed
- **"No active formation" error** — Python schema validation rejected the new object-format `brief_templates` (introduced in 3.20.0). Updated `schema.py` to accept both string and object formats via `oneOf` schema, and `types.py` to use generic `list` type.
- **CLI `---` parsing bug** — session context markers using `---` were parsed as CLI option flags by Typer/Click, causing "No such option" errors. Changed markers to `[Prior conversation]` / `[End of prior conversation]` bracket format.

### Changed
- **Agent personalities** — Council agents now have human names and distinct personalities:
  - `system_architect` → **Marcos Vega** (System Architect)
  - `devops` → **Kira Nakamura** (DevOps Engineer)
  - `product_owner` → **Elena Cortez** (Product Owner)
  - `qa` → **Tomasz Wójcik** (QA Lead)
  - `security_officer` → **Nina Okafor** (Security Officer)
- Agent roles simplified to cleaner titles (e.g., "Technical Architecture Authority" → "System Architect")

## [3.20.0] — Workshop & Briefs Overhaul + Council UI v3

### Fixed
- **Briefs were generating generic garbage** — agents talked about "GraphQL gateways" and "gRPC" instead of the actual project. Root cause: prompts had no codebase context.
- **Removed old useless brief templates** (aig.md, ia_brief.md) that produced AI governance and architecture decision records unrelated to the project.

### Changed
- **Briefs now grounded in actual codebase** — new `gatherProjectContext()` reads README.md, package.json/pyproject.toml, directory structure, formation info, and planning docs to give agents real context about the project.
- **Brief templates now include per-template prompts** — each brief in `formation.json` specifies a `prompt` (what to write), `agent` (which specialist to use), and `name` (human label). Old string-array format still supported (backward compatible).
- **Briefs use single agent instead of full council** — 4x faster generation. Each brief is handled by the most relevant specialist (e.g. security_officer for Security Audit, product_owner for Sprint Brief).
- **Brief generation shows QuickPick** — users can select which briefs to generate, see the prompt preview, and deselect any they don't want.
- **Full Output panel logging** — every brief generation step logs to the NAVIG Output channel with `[BRIEFS]` prefix for visibility.
- **Post-generation actions** — notification offers "Open Folder" and "Open First" buttons after brief generation.
- **Moved "Analyze Project" and "Generate Docs" out of Formation section** — they belong in Workshop Control only. Formation section now focuses on: Agents, Council, Briefs, Documents.
- **Added "Open Briefs Folder" action** in Formation sidebar — quick access to `.navig/plans/briefs/`.

### Council Panel v3
- **3-panel layout** — IRC-style ChatLog (center), Agent Roster sidebar (right, 210px), smart InputBar (bottom)
- **Agent Roster** — per-agent cards with emoji avatar, name, role, status pill (online/thinking/offline), last message snippet
- **Click roster = highlight agent messages**, Shift+click = solo mode (hides other agents' messages)
- **Round separators** — visual dividers between deliberation rounds with "R1", "R2" tags on messages
- **Auto-scroll indicator** — "↓ New messages" bar appears when scrolled up during active deliberation
- **⚡ Seed Question button** — AI-generates a council question based on selected topic (codebase, roadmap, infra, tests, security, product, team)
- **Topic dropdown** — select a topic category before asking or seeding a question
- **@mention routing** — type `@AgentName question` to route directly to a specific agent
- **Responsive layout** — roster collapses on narrow viewports with hamburger toggle
- **Processing state** — roster dots animate to "thinking" pulse during deliberation
- **Agent emojis** — role-based emoji mapping (🏛️ architect, ⚙️ devops, 📋 product, 🔬 qa, 🛡️ security)

## [3.19.0] — Formation Commands Fixed: Analyze, Generate, Briefs

### Fixed
- **JSON parse error "Failed to show formation: Unexpected token 'I'"** — Python CLI logger moved to stderr; stdout reserved for clean JSON output
- **Analyze Project** — was calling non-existent `formation council` CLI command; now uses `council run` with real project document content
- **Generate Docs** — same fix; council deliberation with project context, structured markdown output
- **Generate Briefs** — was calling non-existent `formation briefs` CLI command; now iterates templates and runs council per brief
- **Agent Run** — added JSON extraction safety wrapper for CLI output parsing

### Enhanced
- **Council Panel receives project docs** — agents now see actual document content when deliberating, not just metadata
- **Single-agent tasks** include project docs context too
- **Briefs** are cancellable, include headers with formation name and timestamp

## [3.18.0] — Council Panel v2: Persistent Agent Sessions

### Added
- **Session persistence** — agents remember prior conversation across messages; rolling context window (last 20 turns) is prepended to every new CLI call
- **Start/Stop formation from Council Panel** — header button toggles formation on/off directly from the council chat, with system messages confirming state changes
- **Agent status indicators** — green glowing dots when formation is active (online), gray when stopped (offline), with smooth CSS transitions
- **Configurable deliberation rounds** — dropdown in panel header (1-5 rounds) controls how many discussion rounds the council performs
- **@mention agent targeting** — type `@AgentName message` in chat to route directly to that agent, regardless of which chip is selected
- **Session badge** — shows number of conversation turns stored in memory
- **Online/Offline status badge** — header shows "N online" or "offline" status
- **Live state updates** — `stateUpdate` message pushes status dot and badge changes to webview without full re-render
- **Clear session** — "Clear" button resets both chat messages and session memory

### Changed
- Council Panel header redesigned with formation name, status badge, session badge, rounds control, and Start/Stop/Refresh/Clear buttons
- Agent chips now use status dots (online/offline) instead of colored agent dots
- Empty state messaging adapts: "Council Ready" when active vs "Council Chamber" when stopped
- Input placeholder changes based on formation state

### Added — Formation System (Profile-Based Agent Teams)
- **`navig formation list`** — list all available formations (project + global)
- **`navig formation show <id>`** — display formation details, agents, API connectors
- **`navig formation init <profile>`** — activate a formation for the current workspace
- **`navig formation agents`** — list agents in the active formation
- **`navig agent run <agent_id> --task "<task>"`** — execute a single agent from the active formation with a specified task
- **`navig council run "<question>"`** — run multi-agent council deliberation
- Dynamic formation discovery: no hardcoded maps, community can add formations by placing directories in `formations/` or `~/.navig/formations/`
- 4 built-in formations with 22 specialized agents:
  - **Creative Studio** (6 agents): Creative Director, Designer, Marketing Director, CFO, Dev Lead, Brand Strategist
  - **Football Club** (6 agents): Head Coach, Assistant Coach, Fitness Trainer, Scout, Financial Manager, Data Analyst
  - **Government** (5 agents): Policy Advisor, Budget Officer, Legal Advisor, Public Relations, Strategy Chief
  - **Software Dev Team** (5 agents): System Architect, DevOps, Product Owner, QA Lead, Security Officer
- Council Engine v0: multi-round deliberation with per-agent timeout, confidence scoring, and final decision synthesis
- JSON Schema validation for all formation and agent files
- Supports `--plain` and `--json` output flags for all formation commands
- Formation aliases for flexible lookup (e.g., `creative`, `football`, `gov`, `app_project`)

### Added — VS Code Extension: Formation Integration (Phase 1)
- **Feature Flag**: `navig-bridge.formations.enabled` (default: `false`) — opt-in formations support
- **Profile Resolution**: Extension reads `.navig/profile.json` in workspace root on activation, falls back to `app_project` when missing
- **Switch Formation Command**: `🎯 Switch Formation` — QuickPick with 5 known formations + custom input option (validates ID format)
- **List Agents Command**: `🎯 Formation: List Agents` — Calls CLI `formation show <id> --json`, parses agents, shows in QuickPick
- **Activation Log**: When enabled, logs `[FORMATION] Active formation: <id> (<source>)` on startup
- **Safe Defaults**: When formations disabled, commands register as no-ops with "enable in settings" messages (prevents VS Code "command not found" errors)
- **No Breaking Changes**: All formation code is additive, zero refactoring of existing extension code
- **ProfileConfig**: CLI now supports both integer and string versions in `profile.json` for backward compatibility

### Added — VS Code Extension: Formation Integration (Phase 2)
- **Sidebar Formation Section**: Active formation, agents, and actions displayed in the sidebar tree view under "🎯 Formation" section
- **Agent Tree Nodes**: Agents shown with name, role, council weight — clickable to run agent with a task
- **Default Agent Indicator**: Default agent marked with ⭐ in the sidebar
- **Run Council Command**: `🏛️ Formation: Run Council` — Input question, progress notification, results displayed as markdown document
- **Run Agent Command**: `🤖 Formation: Run Agent` — Select agent + enter task, progress notification, response displayed as markdown
- **Formation Details Command**: `🎯 Formation: Show Details` — Full formation manifest displayed as formatted markdown document
- **Formation Refresh Command**: `🔄 Formation: Refresh` — Invalidate caches and reload from CLI, refresh sidebar
- **Profile Watcher**: FileSystemWatcher monitors `.navig/profile.json` — sidebar auto-updates when profile changes
- **Formation Caching**: Resolution and detail caches invalidated on profile change, reducing CLI calls
- **Event System**: `onDidChangeFormation` event fires when profile changes, sidebar refreshes automatically

### Changed — Formation Auto-Detection (Phase 3)
- **Auto-detect formation per project**: On first activation in a workspace with no `.navig/profile.json`, NAVIG scans project files (package.json, pyproject.toml, Cargo.toml, etc.) and automatically selects the best-fit formation
- **One-time setup**: Auto-detected formation is persisted to `.navig/profile.json` — no repeated prompts, no manual switching required
- **Subtle notification**: When auto-detected, shows `"Formation auto-set: <id>"` with a "Change" button for overriding
- **Switch Formation de-emphasized**: Removed from sidebar top-level; still accessible via Command Palette (`formation.switch`) or notification "Change" action
- **New source type `auto`**: FormationResolution now reports `source: 'auto'` when formation was auto-detected, alongside existing `file` and `default` sources

### Added — Windows System Tray Launcher
- **`navig tray start`** — launch NAVIG tray app (system tray icon near clock)
- **`navig tray stop`** — terminate the running tray process
- **`navig tray status`** — check if tray is running (supports `--json`)
- **`navig tray install`** — create desktop shortcut + optional auto-start (`--auto-start`)
- **`navig tray uninstall`** — remove auto-start, shortcut, and settings
- Right-click tray icon to start/stop Gateway and Agent services
- Color-coded status indicator on tray icon (green=running, red=error, yellow=starting)
- Quick actions submenu: open dashboard, host status, vault, skills
- Auto-start with Windows via registry key (toggle from tray menu)
- Single-instance enforcement via PID lock file
- Health monitoring thread checks process status every 15 seconds
- PowerShell installer script (`scripts/install-tray.ps1`) for automated setup

### Added — Skill Execution Routing
- **`navig skills show <name>`** — display detailed skill info: commands, examples, metadata, entrypoint
- **`navig skills run <skill>:<command> [args]`** — execute skill commands via CLI bridge
- Skill commands from SKILL.md frontmatter (`navig-commands`) are now routed to the CLI
- Skills with Python or JS entrypoints (`main.py`, `index.js`) can be run directly

  - `--tool nuitka` - Build with Nuitka (smaller/faster binary, ~25MB)
  - `--compare` - Benchmark both tools and compare results
  - `--measure-startup` - Analyze import times and identify bottlenecks
  - `--compile-bytecode` - Pre-compile all .py files for faster imports
- Added `docs/building.md` - comprehensive guide for building binary distributions
- Added `docs/development.md` - development setup guide with modern tooling:
  - `uv` support for 10-100x faster dependency installation
  - `rye` support for full project management
- Extended lazy-loading to scaffold commands for faster startup
- Verified bytecode compilation in .gitignore (`__pycache__/`, `*.pyc`)

### 🚀 Onboarding, Status, JSON Output (2025-12-26)

- Adds `navig quickstart` for fast onboarding in new projects.
- Adds `navig status` to show active host/app and tunnel state (supports `--plain` and `--json`).
- Adds short aliases: `h` (host), `a` (app), `f` (file), `t` (tunnel), `r` (run).
- Expands `--json` support across core commands (host/app/file/db/tunnel/run) with a stable JSON envelope (`schema_version`, `command`, `success`, …).
- Adds TTL-based caches under `~/.navig/cache/` for discovery-style operations and respects `--no-cache`.
- Fixes a spurious "global config directory not accessible" error on fresh installs/test environments.
- Improves host list cache invalidation reliability on Windows.

### 🛡️ PowerShell Safety (2025-12-27)

- Adds automatic PowerShell quoting issue detection for `navig run` commands.
- When complex commands with `()`, `{}`, `$` are detected on PowerShell, navig now shows helpful guidance suggesting `--stdin`, `--file`, or `-i` (interactive editor) to avoid shell parsing errors.
- Adds early error detection that catches when PowerShell mangles commands BEFORE they reach navig (e.g., "Got unexpected extra arguments" errors) and provides immediate, actionable solutions.
- Updates `navig run --help` to prominently warn PowerShell users about quoting issues.

### 🗄️ Database Improvements (2025-12-27)

- **Rich formatted output for database queries** - DESCRIBE, SELECT, and SHOW queries now display with proper column alignment, colors, and semantic highlighting:
  - Column types color-coded: integers (green), strings (cyan), enums (yellow), dates (blue)

### 📁 File Operations Improvements (2025-12-27)

- **Line range support for `navig file show`** - You can now specify line ranges using `--lines 100-200` or `--lines 100:200` to view specific sections of files without needing `sed` commands.
  - Example: `navig file show app.log --lines 800-850`
  - Uses `sed -n 'start,endp'` internally for efficient range extraction.
- Fixed overly aggressive "complex command" warning that triggered on safe commands with semicolons and pipes.
- **Improved `--b64` output display** - When using base64-encoded commands, navig now shows the original decoded command in the "Executing:" message instead of the confusing base64 string.
  - Before: `ℹ Executing: WTJRZ0wyaHZiV1UxTDJONVltVnphWE12Y0hWaWJHbGpYMmgwYld3dmFHOWlhWFZ6SUN…`
  - After: `ℹ Executing: cd /home/user/project && php artisan tinker --execute='App\Models\User::count();'`
  - Keys highlighted: PRI (bold yellow), UNI (yellow), MUL (dim yellow)
  - NULL values dimmed, auto_increment marked in magenta
  - Use `--plain` to get unformatted output for scripting
- **Auto-detection of base64 queries** - `navig db query` now automatically detects base64-encoded SQL, no flags needed!
- Adds `--b64` flag to `navig db query` for forced base64 decoding (usually auto-detected).
- Adds missing `--plain` flag to `navig db query` for clean, script-friendly output.
- Adds `--raw` as an alias for `--plain` flag (more intuitive naming).
- Improves database authentication error messages: now shows which credentials were attempted and provides 4 specific solutions.
- Automatically uses `mariadb` command instead of deprecated `mysql` when MariaDB is detected.
- Filters out "Deprecated program name" warnings from stderr for cleaner output.

### 🐛 Bug Fixes (2025-12-27)

- Fixes duplicate checkmarks in success messages - removed redundant symbols since `ch.success()` already adds them (e.g., "✓ ✓ Upload complete" now shows as "✓ Upload complete")
- Fixes `AttributeError` in app edit functionality: replaced invalid `config_manager.config_dir` with correct `config_manager.global_config_dir` and `config_manager.apps_dir` attributes.
- Fixes `navig file list` generating invalid `ls --l-h` command (now correctly generates `ls -lh`)
- Fixes database credential resolution in `navig db query`: now properly reads credentials from app/host config instead of always using default "root" user.
- Improves database authentication error messages: shows "(yes)" or "(no)" for password presence instead of misleading "(provided)/(none)" text.
- Changes confirmation prompt default from "No" to "Yes" for non-critical operations (destructive operations still default to "No" for safety).
- **Fixes critical config loading bug**: Global config (including `execution.mode`) was not being loaded when in project directories, causing `execution.mode: auto` to be ignored.
- Suppresses diagnostic messages (`Detected: <type>`) in `--plain` mode for pure scripting output.
- Improves `db query --json` output to be strictly machine-parseable (no extra diagnostic lines).

### 🧭 CLI UX & In-App Help (2025-12-26)

- Adds `python -m navig` support via package entrypoint.
- Adds `navig help` / `navig help <topic>` with markdown-backed topics (and fallback to the centralized help registry).
- Updates handbook examples to prefer canonical `navig file ...` commands while keeping legacy `navig upload/download` compatibility.
- Speeds up top-level `navig` / `navig --help` / `navig --version` by handling them in a minimal fast path (avoids Rich import and fixes Windows console encoding issues).

### 🧩 Config Validation & Schemas (2025-12-26)

- Adds `navig config validate` (and keeps `navig config test` as an alias) with file+line error reporting.
- Adds `navig config schema install` to install YAML JSON schemas for hosts/apps (optional VS Code settings writer).
- Adds global `--no-cache` to disable local caches for a run.

---

### 🏗️ CLI 4-Pillar Architecture Refactoring (2025-01-XX)

**Consolidated 20+ top-level commands into a clean 4-pillar structure!**

The CLI has been reorganized into four logical pillars for better discoverability:

**Pillar 1: Infrastructure (`host`)**
- `navig host monitor` - Server monitoring (resources, disk, health)
- `navig host security` - Security management (firewall, fail2ban, SSH)
- `navig host maintenance` - System maintenance (updates, cleanup)

**Pillar 2: Services (`app`, `docker`, `web`)**
- `navig web hestia` - HestiaCP panel management (nested under web)

**Pillar 3: Data (`db`, `file`, `log`, `backup`)**
- Unchanged - already well-organized

**Pillar 4: Automation (`flow`, `ai`, `wiki`)**
- `navig flow` - Workflow/task management (renamed from `workflow`/`task`)
- `navig flow template` - Template management (consolidates `template` + `addon`)

**Migration Path (Deprecated Commands):**
Commands that have moved now show deprecation warnings but continue to work:
- `navig monitor` → `navig host monitor`
- `navig security` → `navig host security`
- `navig system` → `navig host maintenance`
- `navig server` → `navig host`
- `navig workflow` → `navig flow`
- `navig task` → `navig flow`
- `navig template` → `navig flow template`
- `navig addon` → `navig flow template`
- `navig hestia` → `navig web hestia`

Deprecated commands are hidden from `--help` but remain functional during transition period.

---

### 🖥️ Local OS Management Module (2025-01-XX)

**Treat your local machine as a managed host!**

NAVIG now supports managing your local machine with the same commands used for remote hosts.

**New Commands:**
```bash
navig host use local           # Switch to local machine
navig hosts view               # View local hosts file
navig hosts edit               # Edit hosts file (with admin elevation)
navig software list            # List installed packages (winget/apt/brew)
navig security audit           # Run local security audit
```

**Architecture:**
- **ConnectionAdapter pattern**: Unified interface for local (`subprocess`) and remote (`ssh`) execution
- **OS Adapters**: Strategy pattern with Windows, Linux, and macOS implementations
- **Auto-detection**: Automatically creates `local.yaml` host config on first use
- **Cross-platform**: Works on Windows (winget, PowerShell), Linux (apt/yum/dnf), macOS (brew)

**Security Audit Checks:**
- Firewall status
- Open ports
- User accounts with login shells
- SSH configuration
- World-writable files
- Admin/root privilege detection

**New Files:**
- `navig/core/connection.py` - ConnectionAdapter, LocalConnection, SSHConnection
- `navig/adapters/os/` - OSAdapter base + Windows/Linux/macOS implementations
- `navig/local_operations.py` - LocalMachine unified operations class
- `navig/commands/local.py` - CLI commands for local management

**Tests:** 64 new tests (21 connection + 43 OS adapters)

---

### 🎨 UI/UX: Category-Based Help & Interactive Menu Redesign (2025-12-10)

**Reorganized CLI help and interactive menu for better discoverability!**

**`navig --help` now shows category-based grouping:**
```
═══ QUICK START ═══
  init         Initialize project-local .navig/ directory
  host add     Add a new remote server
  menu         Launch interactive command center

═══ CORE RESOURCES ═══
  host, app, db, file, docker

═══ REMOTE OPERATIONS ═══
  run, install, server, system, web

═══ SECURITY & NETWORKING ═══
  security, tunnel

═══ INTELLIGENCE & AUTOMATION ═══
  ai, wiki, workflow
```

**Interactive menu (`navig menu`) redesigned with 4-section layout:**
- **SERVERS & APPS**: Host, App, Remote Execution, Files, Docker
- **DATA & SYSTEM**: Database, Webserver, Maintenance, Backup
- **INTELLIGENCE**: AI Assistant, Wiki & Documentation
- **SYSTEM**: Configuration, Command History

**New menu features:**
- Enhanced context display with host IP and timestamp
- New Docker Containers submenu
- New Remote Execution submenu
- New Wiki & Documentation submenu
- Keyboard shortcuts (letters A, W, C, H for quick access)

### 🏗️ CLI Architecture Refactoring (7 Pillars)

**Industry-standard noun-verb pattern like Docker, Kubernetes, and GitHub CLI!**

NAVIG now follows the `navig <resource> <action>` pattern organized into 7 pillars:

| Pillar | Resource Groups | Purpose |
|--------|-----------------|---------|
| **1. Infrastructure** | `host` | Remote server management |
| **2. File System** | `file`, `log` | Remote file and log operations |
| **3. Data** | `db`, `backup` | Database and backup management |
| **4. Applications** | `app`, `web`, `docker` | Application lifecycle |
| **5. Security** | `security`, `tunnel` | Security and SSH tunnels |
| **6. Intelligence** | `ai`, `wiki` | AI assistance and knowledge base |
| **7. System** | `system`, `config`, `monitor` | System maintenance |

**New canonical commands:**
- `navig file add/get/list/show/edit/remove` - File operations
- `navig db list/tables/run/dump/restore` - Database operations
- `navig backup list/run/restore` - Backup management
- `navig ai ask/analyze/context/status/config/reset` - Unified AI assistant
- `navig system show/update/clean/run/reboot` - System maintenance

**Deprecated commands** (still work with deprecation warnings):
- `navig upload` → `navig file add`
- `navig download` → `navig file get`
- `navig ls/tree` → `navig file list`
- `navig chmod/chown` → `navig file edit --mode/--owner`
- `navig db-list/db-query` → `navig db list/run`
- `navig logs/health/restart` → `navig log show/monitor show/system run`
- `navig backup-*` → `navig backup run --<type>`
- `navig assistant *` → `navig ai *`

**Full backward compatibility maintained** - all old commands continue to work.

### ⚡ Performance Optimization (2025-12-10)

**56% faster CLI import time!**

Comprehensive performance optimization for CLI startup and config operations:

| Metric | Before | After | Improvement |
|--------|--------|-------|-------------|
| CLI import | 528ms | 231ms | **56%** |
| `navig --help` | 530ms | 71ms | **87%** |
| `navig host list` | 542ms | 99ms | **82%** |
| `list_hosts()` (cold) | 10ms | 4.9ms | **51%** |
| `list_hosts()` (warm) | 10ms | 0.6ms | **94%** |

**Key optimizations:**
- Lazy import of paramiko in `discovery.py` (saves 238ms for non-SSH commands)
- Deferred loading of `ServerDiscovery` in `commands/host.py`
- Directory listing cache with mtime-based invalidation for `list_hosts()`
- In-memory caching for host configurations with automatic invalidation

**New benchmark suite:** `tests/benchmarks/test_performance.py`

### 📚 Wiki Knowledge Base System (2025-12-10)

**Manage project documentation with AI-powered categorization!**

New `navig wiki` module provides a structured knowledge base for each project:

```bash
# Initialize wiki
navig wiki init                        # Create .navig/wiki/ structure
navig wiki init --global               # Create global wiki at ~/.navig/wiki/

# Content management
navig wiki list                        # List all wiki pages
navig wiki show <page>                 # View a wiki page
navig wiki add <file>                  # Add file to inbox
navig wiki add <file> --folder hub/tasks  # Add to specific folder
navig wiki edit <page>                 # Open in editor
navig wiki remove <page>               # Archive page
navig wiki search <query>              # Full-text search

# Inbox processing with AI categorization
navig wiki inbox                       # Show pending items
navig wiki inbox process               # AI-categorize inbox items
navig wiki inbox process --auto        # Auto-move to suggested folders

# Wiki links
navig wiki links                       # Link statistics
navig wiki links broken                # Find broken [[wiki-links]]

# Publishing
navig wiki publish                     # Export public content
navig wiki publish --preview           # Preview what would be published
```

#### Wiki Structure

```
.navig/wiki/
├── inbox/           # Drop files here for AI processing
├── .meta/           # Configuration & indexes
├── knowledge/       # Encyclopedia (configurable public/private)
├── technical/       # Technical documentation
├── hub/             # Project command center (roadmap, tasks, planning)
├── external/        # Business & marketing materials
└── archive/         # Archived content
```

#### Features

- **[[wiki-links]]** syntax for cross-referencing pages
- **AI categorization** - Auto-suggests destination folders
- **Global + project wikis** - Share knowledge across projects
- **Visibility control** - Mark content as public/private for publishing

### 🎯 CLI Standardization (2025-12-10)

**Consistent command structure with canonical actions!**

NAVIG now follows a standardized `navig <resource> <action>` pattern with canonical actions.
All legacy commands continue to work but show deprecation warnings pointing to the new canonical form.

#### New Canonical Actions

Every resource now supports these standard actions (where applicable):
- `add` - Create new resource
- `list` - List resources
- `show` - Show detailed information
- `edit` - Modify existing resource
- `update` - Update/sync resource
- `remove` - Delete resource
- `run` - Execute/start operation
- `test` - Test/validate resource
- `use` - Set active/default resource

#### New Resource Groups

- **`navig file`** - Unified file operations
  ```bash
  navig file add <local> <remote>     # Upload file
  navig file add --dir <path>         # Create directory
  navig file list [path]              # List remote directory
  navig file show <path>              # View file contents
  navig file show <path> --download   # Download file
  navig file edit <path> --content    # Write to file
  navig file edit <path> --mode 755   # Change permissions
  navig file remove <path>            # Delete file/directory
  ```

- **`navig log`** - Log viewing and management
  ```bash
  navig log show <service>            # View logs
  navig log show --follow             # Tail logs
  ```

- **`navig server`** - Unified server operations
  ```bash
  navig server list                   # List containers/services
  navig server show <name>            # Inspect container
  navig server run <name> <cmd>       # Execute in container
  navig server add <name>             # Start container
  navig server remove <name>          # Stop container
  navig server update <name>          # Restart container
  ```

- **`navig task`** - Alias for workflow
  ```bash
  navig task list                     # Same as navig workflow list
  navig task run <name>               # Same as navig workflow run
  ```

#### Command Migrations

| Old Command | New Canonical | Status |
|------------|---------------|--------|
| `navig host info` | `navig host show` | Deprecated with warning |
| `navig host current` | `navig host show --current` | Deprecated with warning |
| `navig host default <n>` | `navig host use <n> --default` | Deprecated with warning |
| `navig host clone` | `navig host add --from` | Deprecated with warning |
| `navig tunnel start` | `navig tunnel run` | Deprecated with warning |
| `navig tunnel stop` | `navig tunnel remove` | Deprecated with warning |
| `navig tunnel status` | `navig tunnel show` | Deprecated with warning |
| `navig db shell` | `navig db run --shell` | Deprecated with warning |
| `navig backup list` | `navig backup show` | Deprecated with warning |
| `navig backup delete` | `navig backup remove` | Deprecated with warning |
| `navig workflow create` | `navig workflow add` | Deprecated with warning |
| `navig workflow delete` | `navig workflow remove` | Deprecated with warning |
| `navig workflow validate` | `navig workflow test` | Deprecated with warning |
| `navig config validate` | `navig config test` | Deprecated with warning |

#### Backward Compatibility

All legacy commands continue to work but print deprecation warnings:
```
⚠️  DEPRECATED: 'navig tunnel start' → Use 'navig tunnel run' instead
```

The deprecation warnings help AI coding assistants learn the canonical forms for better command suggestions.

### 🔄 Workflow System (2025-12-08)

**Automate complex operations with reusable command workflows!**

The new Workflow System lets you define and execute sequences of NAVIG commands as reusable YAML workflows.

#### Features

- **Workflow Commands**:
  ```bash
  navig workflow list                    # List all workflows
  navig workflow run <name>              # Execute a workflow
  navig workflow run <name> --dry-run    # Preview without executing
  navig workflow show <name>             # Display workflow definition
  navig workflow validate <name>         # Validate syntax
  navig workflow create <name>           # Create from template
  navig workflow delete <name>           # Delete a workflow
  navig workflow edit <name>             # Open in editor
  ```

- **Variable Substitution**: Define reusable variables with defaults
  ```bash
  navig workflow run db-snapshot --var host=staging --var db_name=mydb
  ```

- **Conditional Execution**:
  - `continue_on_error: true` - Keep going if step fails
  - `skip_on_error: true` - Skip step if previous failed
  - `prompt: "Question?"` - Ask for user confirmation

- **Multi-scope Storage**:
  - Project-local: `.navig/workflows/` (highest priority)
  - Global: `~/.navig/workflows/`
  - Built-in: Bundled example workflows

#### Built-in Workflows

- **safe-deployment** - Deploy with health checks and rollback safety
- **db-snapshot** - Export database for local development
- **emergency-debug** - Rapid diagnostics for failing services
- **server-health** - Comprehensive server health check

#### Example Usage

```bash
# Preview a deployment workflow
navig workflow run safe-deployment --dry-run

# Execute with custom variables
navig workflow run db-snapshot --var db_name=production_db --yes

# Create your own workflow
navig workflow create my-deployment
```

See `docs/WORKFLOWS.md` for complete documentation.

### 🔌 Plugin System (2025-12-08)

**Extend NAVIG with custom commands and integrations!**

NAVIG now supports a modular plugin architecture that allows you to add custom functionality without modifying the core codebase.

#### Features

- **Plugin Discovery**: Automatically discovers plugins from three locations:
  - Built-in plugins (`navig/plugins/`)
  - User plugins (`~/.navig/plugins/`)
  - Project plugins (`.navig/plugins/`)

- **Plugin Management Commands**:
  ```bash
  navig plugin list              # List all plugins
  navig plugin info <name>       # Show plugin details
  navig plugin enable <name>     # Enable a plugin
  navig plugin disable <name>    # Disable a plugin
  navig plugin install <path>    # Install from local path
  navig plugin uninstall <name>  # Remove user plugin
  ```

- **Plugin API**: Plugins can safely access NAVIG's core functionality:
  - Execute remote commands via SSH
  - Read/write configuration
  - Access active host/app context
  - Use NAVIG's console output helpers

- **Graceful Failure**: Plugins with missing dependencies or errors won't break NAVIG - they simply won't load

#### Example Plugin

The built-in `hello` plugin demonstrates plugin development:

```bash
navig hello greet --name "Developer"
# ✓ Hello, Developer!

navig hello info
# Shows plugin info and current NAVIG context
```

#### Create Your Own Plugin

1. Create a directory in `~/.navig/plugins/my-plugin/`
2. Add `plugin.py` with required exports (`name`, `app`, `check_dependencies`)
3. Run `navig plugin list` to verify it's loaded

See `docs/PLUGIN_DEVELOPMENT.md` for the complete developer guide.

### 📚 Documentation Reorganization (2025-12-08)

**Cleaner project structure with consolidated documentation!**

- Moved `USAGE_GUIDE.md` and `INSTALLATION.md` to `/docs/` folder
- Moved internal reports to `.github/reports/` folder
- Fixed broken links to deleted `workflows.md` file
- Updated README.md with proper documentation table
- Improved troubleshooting guide with PowerShell-specific escaping tips
- Added common `--b64` and interactive mode error solutions

### 🚀 Complex Command Execution (2025-12-08)

**Execute commands with JSON, special characters, and multi-line scripts without escaping issues!**

The `navig run` command now supports multiple input methods to handle complex commands that would otherwise fail due to shell escaping conflicts.

#### Base64 Transport Mode (`--b64`)

Use `--b64` flag to encode commands as Base64, completely bypassing shell escaping:

```bash
# JSON payloads now work perfectly
navig run --b64 "curl -d '{\"user\":\"john\"}' api.com"

# Special characters preserved
navig run --b64 "echo \$HOME && ls \$(pwd)"
```

#### File and Stdin Input

Read commands from files or stdin for complex scripts:

```bash
# From file
navig run @script.sh

# From stdin
echo "complex command" | navig run "@-"

# Interactive editor
navig run -i
```

#### When to Use Each Method

| Scenario | Method |
|----------|--------|
| Simple command | `navig run "ls -la"` |
| JSON payload | `navig run --b64 "curl -d '{...}'"` |
| Special characters | `navig run --b64 "..."` |
| Multi-line script | `navig run @script.sh` |
| Quick multi-line | `navig run -i` |

### 🎯 Simplified Command Structure (2025-12-08)

**Commands are now organized into intuitive groups!**

NAVIG commands have been reorganized into logical groups for easier discovery and use. All old commands still work with deprecation warnings.

#### New Command Groups

| Group | Description | Example |
|-------|-------------|---------|
| `navig db` | All database operations | `navig db list`, `navig db query`, `navig db dump` |
| `navig monitor` | Server monitoring | `navig monitor health`, `navig monitor disk` |
| `navig security` | Security management | `navig security firewall`, `navig security scan` |
| `navig web` | Web server control | `navig web vhosts`, `navig web reload` |

#### Interactive Menus

Run any group without a subcommand to open its interactive menu:
- `navig db` → Database operations menu
- `navig monitor` → Monitoring menu
- `navig security` → Security menu
- `navig web` → Web server menu

#### Backward Compatibility

Old commands still work but show deprecation warnings:
```
⚠ 'navig firewall-status' is deprecated. Use 'navig security firewall' instead.
```

### 📋 Plain Text Output for All List Commands (2025-12-08)

**New `--plain` flag for scripting and automation!**

All list commands now support a `--plain` flag that outputs one item per line, making it easy to pipe output to other commands or use in scripts.

#### Commands with `--plain` Support

| Command | Plain Output |
|---------|--------------|
| `navig host list --plain` | One host name per line |
| `navig app list --plain` | One app name per line |
| `navig tunnel status --plain` | "running" or "stopped" |
| `navig template list --plain` | One template name per line |
| `navig mcp list --plain` | One MCP server name per line |
| `navig backup list --plain` | One backup file name per line |
| `navig hestia users --plain` | One username per line |
| `navig hestia domains --plain` | One domain per line |
| `navig db-databases --plain` | One database name per line |
| `navig db-show-tables --plain` | One table name per line |
| `navig server-template list --plain` | One template name per line |

#### Example Usage

```bash
# Loop through all hosts
for host in $(navig host list --plain); do
    echo "Processing $host..."
done

# Count databases
navig db-databases --plain | wc -l

# Check if tunnel is running
if [ "$(navig tunnel status --plain)" = "running" ]; then
    echo "Tunnel is active"
fi
```

### ✨ Interactive Mode for All Command Groups (2025-12-08)

**Run any command group without subcommand to launch its interactive menu!**

Now you can simply type `navig host`, `navig app`, `navig tunnel`, etc. without any subcommand to launch an interactive menu for that command group. This provides a consistent, discoverable UX across all NAVIG features.

#### New Interactive Modes

| Command | What Happens |
|---------|--------------|
| `navig host` | Opens Host Management menu |
| `navig app` | Opens App Management menu |
| `navig tunnel` | Opens Tunnel Operations menu |
| `navig config` | Opens Configuration menu |
| `navig backup` | Opens Backup & Export menu |
| `navig assistant` | Opens AI Assistant menu |
| `navig template` | Opens Template Management menu |
| `navig mcp` | Opens MCP Server Management menu |
| `navig hestia` | Opens HestiaCP Management menu |

All menus feature:
- Consistent Mr. Robot-inspired visual theme
- Categorized options with clear separators
- Number-based selection (no arrow keys required)
- Context display showing active host/app
- Press `0` or `Ctrl+C` to go back

**Note:** All existing CLI commands continue to work exactly as before. This is purely additive - `navig host list`, `navig app use myapp`, etc. work unchanged.

---

### 🏗️ ARCHITECTURE - Simplified Host/App Selection System (2025-01-08)

**Major simplification of how NAVIG selects the active host and app.**

#### New Resolution Order (Host)

```
1. NAVIG_ACTIVE_HOST env var     ← For CI/CD and scripting
         ↓
2. .navig/config.yaml:active_host ← Project-local preference (NEW!)
         ↓
3. ~/.navig/cache/active_host.txt ← Global cache (navig host use)
         ↓
4. default_host from config      ← Fallback
```

#### New Resolution Order (App)

```
1. NAVIG_ACTIVE_APP env var      ← For CI/CD and scripting
         ↓
2. .navig/config.yaml:active_app ← Project-local preference
         ↓
3. ~/.navig/cache/active_app.txt ← Global cache (navig app use)
         ↓
4. default_app from host config  ← Fallback
```

#### Key Changes

**Added:**
- `active_host` field in project `.navig/config.yaml` for project-local host preference
- `navig host current` now shows the source of the active host (env, local, global, default)
- Better messaging when local config overrides global setting

**Removed:**
- `--session` flag from `navig host use` (was confusing - couldn't actually set env var)
- `scripts/navig-session.ps1` workaround script

**Why this is better:**
- Each project can define its preferred host in `.navig/config.yaml`
- Multi-project developers get automatic isolation (each project uses its own host)
- DevOps quick-switching still works via `navig host use` (global cache)
- Environment variables still work for CI/CD and advanced users
- No more confusing `--session` flag that didn't actually work

#### Example: Project-Local Host Configuration

```yaml
# .navig/config.yaml (commit this to git)
active_host: production
active_app: my-app

app:
  name: my-project
  version: '1.0'
```

Now when you `cd` into this project, NAVIG automatically uses the `production` host!

---

### 🐛 BUG FIX - Apps No Longer Appear in Hosts List (2025-01-06)

**Fixed:** Apps stored in `~/.navig/apps/` were incorrectly appearing in `navig host list`.

**Root Cause:** The legacy compatibility code in `list_hosts()` was adding ALL files from the apps directory to the hosts list without checking if they were host configs or app configs.

**Solution:** Now properly distinguishes between:
- **Host configs** - Have an IP address or FQDN in the `host` field (e.g., `host: 10.0.0.10`)
- **App configs** - Reference a host by name (e.g., `host: vultr`)

Files in `apps/` that reference another host by name are now correctly excluded from the hosts list.

---

### 🛡️ NEW - Execution Modes with Configurable Confirmation Levels (2025-01-06)

**Control when NAVIG prompts for confirmation before executing commands:**

Two execution modes:
- **`interactive`** (default) - Prompts for confirmation based on confirmation level
- **`auto`** - Skips all confirmations (for scripts/automation)

Three confirmation levels:
- **`critical`** - Only confirm destructive operations (rm -rf, DROP TABLE, etc.)
- **`standard`** (default) - Confirm critical + modify operations (UPDATE, file uploads)
- **`verbose`** - Confirm all remote operations

**New Commands:**
```bash
# View current settings
navig config settings

# Change execution mode
navig config set-mode auto          # Skip all confirmations
navig config set-mode interactive   # Prompt based on level

# Change confirmation level
navig config set-confirmation-level critical  # Only destructive ops
navig config set-confirmation-level standard  # Default behavior
navig config set-confirmation-level verbose   # Confirm everything
```

**New CLI Flags:**
- **`--yes`, `-y`** - Auto-confirm for a single command
- **`--confirm`, `-c`** - Force confirmation even in auto mode

**Examples:**
```bash
# Auto-confirm single command
navig -y run "rm /var/log/app/*.log"

# Force confirmation in auto mode
navig -c run "DROP DATABASE test"

# Check settings
navig config settings
```

---

### 📦 NEW - Configuration Export/Import System (2025-01-06)

**Backup, export, and share NAVIG configuration between machines:**

**New Commands:**
- **`navig backup export`** - Export configuration to backup file
- **`navig backup import`** - Import configuration from backup file
- **`navig backup list`** - List available backups
- **`navig backup inspect`** - Preview backup contents without importing
- **`navig backup delete`** - Delete a backup file

**Features:**
- Export formats: JSON (readable) or archive (.tar.gz)
- Optional AES-256 encryption with password protection
- Automatic secret redaction (passwords, API keys) for safe sharing
- Merge or overwrite modes for imports
- Timestamped backups with size information

**Examples:**
```bash
# Export all config to JSON (secrets redacted)
navig backup export

# Export with encryption
navig backup export --encrypt --format archive

# List available backups
navig backup list

# Preview before importing
navig backup inspect navig-export-2025-01-06.json

# Import with merge (keeps existing config)
navig backup import navig-export.json

# Import with overwrite
navig backup import navig-export.json --overwrite
```

---

### 🔧 FIX - Complex Command Escaping (2025-12-06)

**Fixed issues with running complex commands containing heredocs, JSON, or special characters from PowerShell:**

When running commands like creating JSON config files with heredocs, special characters (quotes, colons, backslashes) were being incorrectly parsed due to multiple escaping layers (PowerShell → Python CLI → SSH).

**New Options Added:**
- **`--stdin`, `-s`** - Read command from stdin, bypassing shell escaping
- **`--file`, `-f`** - Read command from a file, ideal for complex scripts

**Usage:**
```bash
# Simple commands still work as before
navig run "ls -la"

# Complex commands: use --file
navig run --file my_script.sh

# Or pipe via stdin
cat script.sh | navig run --stdin

# PowerShell here-strings work great
@'
cat > config.json << 'EOF'
{"api_key": "xyz", "url": "https://example.com"}
EOF
'@ | navig run --stdin
```

**Tip:** For JSON config files, consider using `navig upload` instead:
```bash
navig upload config.json /var/www/config.json
```

---

### 🗄️ NEW - Docker Database Management (2025-12-06)

### 🐛 FIXED - Critical Bug Fixes (2025-11-26)

**Fixed 22 failing tests and several critical bugs**:

#### Variable Shadowing Bug in Interactive Menu
- **`navig/commands/interactive.py`**: Fixed critical variable shadowing bug where `for app in apps:` overwrote the imported `app` module
  - Changed loop variable from `app` to `app_item` in 5 locations:
    - `execute_app_edit()` - lines 1218, 1294
    - `execute_app_clone()` - line 1323
    - `execute_app_info()` - line 1358
    - `execute_app_remove()` - line 1398
  - This prevented `app.edit_app()`, `app.clone_app()` etc. from being called correctly

#### Config Manager Attribute Bug
- **`navig/config.py`**: Fixed `save_app_config()` referencing non-existent `self.config_dir` attribute
  - Changed to correct `self.base_dir` attribute

#### Test Fixture Isolation Fixes
- **`tests/test_config.py`**: Fixed `config_manager` fixture to pass explicit `config_dir` parameter
  - Prevents tests from picking up the project's actual `.navig` directory
- **`tests/test_cli_enhancements.py`**: Same fixture isolation fix
- **`tests/test_interactive_menu_fixes.py`**: Fixed test expectation - `inspect_host` receives `{'silent': True}` not empty dict
- **`tests/test_security_fixes.py`**: Fixed mock patches to use correct module paths:
  - `navig.config.get_config_manager` instead of `navig.commands.database_advanced.get_config_manager`
  - `navig.tunnel.TunnelManager` instead of `navig.commands.database_advanced.TunnelManager`
- **`tests/test_integration.py`**: Simplified to focus on import and API correctness tests
- **`tests/test_template_manager.py`**: Changed bare `except:` to `except (OSError, PermissionError):`

#### Test Results
- All 210 tests now pass
- Coverage: 23% overall, 53-91% on critical modules (config, template_manager, migration, proactive_assistant)

### 🔧 IMPROVED - Template System Consistency (Complete YAML Migration)

**Completed migration from JSON to YAML format across the template system**:

#### Template Discovery Fix
- **`navig/template_manager.py`**: Fixed `discover_templates()` to check for both `template.yaml` and `template.json` files (previously only checked JSON)
- YAML format now preferred, JSON supported for backward compatibility
- Warning messages now correctly reference both formats

#### Removed Duplicate Template Files
- Deleted `template.json` files from all bundled templates (keeping only YAML):
  - `templates/gitea/template.json` → removed
  - `templates/hestiacp/template.json` → removed
  - `templates/n8n/template.json` → removed

#### Updated Customization Format
- **`navig/server_template_manager.py`**: Changed per-server template customizations from JSON to YAML
  - Customization files now saved as `~/.navig/apps/<server>/templates/<template>.yaml`
  - Backward compatible: reads existing JSON files, writes new YAML
- Updated documentation strings to reference YAML format

#### Updated Documentation References
- Changed all user-facing messages from `template.json` to `template.yaml`
- Updated docstrings in `template_manager.py`, `commands/template.py`, `commands/server_template.py`

### 🔒 IMPROVED - Code Quality Fixes

**Fixed bare exception handlers across the codebase**:

- **`navig/modules/context_generator.py`**: Replaced 5 bare `except:` blocks with specific exceptions:
  - `ImportError, AttributeError` for version imports
  - `Exception` for optional feature failures
  - `OSError, json.JSONDecodeError` for file operations
- **`navig/commands/database.py`**: Changed bare `except:` to `OSError` for cleanup operations

### 📋 IMPROVED - MCP Server Directory

**Expanded MCP server search directory**:

- **`navig/mcp_manager.py`**: Added 7 additional official MCP servers to search:
  - `memory` - Persistent knowledge graph memory
  - `puppeteer` - Browser automation
  - `fetch` - HTTP content retrieval
  - `slack` - Slack workspace integration
  - `postgres` - PostgreSQL database access
  - `google-drive` - Google Drive file access
  - `google-maps` - Google Maps API

### 🐛 FIXED - Webserver Timestamp Placeholder

- **`navig/commands/webserver.py`**: Fixed hardcoded `'2024-01-01'` placeholder with actual `datetime.now().isoformat()`

---

### 🔒 SECURITY - Critical Security Fixes

**Multiple security vulnerabilities fixed**:

#### **Removed shell=True Subprocess Vulnerabilities**
- **`navig/commands/backup.py`**: Added `_run_scp_command()` helper function to build SCP commands as list instead of string with `shell=True`. Fixes 6 potential command injection points.
- **`navig/commands/host.py`**: Added `shlex.split()` for editor command execution, preventing shell injection.
- **`navig/commands/app.py`**: Added `shlex.split()` for editor command execution, preventing shell injection.

#### **Removed Hardcoded SSH Credentials in Tests**
- **`tests/test_discovery.py`**: Replaced hardcoded SSH password with mocked unit tests
- **`tests/test_keys.py`**: Replaced hardcoded SSH credentials with proper mocked tests

### ⚡ PERFORMANCE - ConfigManager Singleton Pattern

**New factory function `get_config_manager()`** implements singleton pattern for improved performance:

- **Problem**: Every command instantiated a new `ConfigManager()`, causing repeated filesystem traversal and YAML parsing (~50-100ms each).
- **Solution**: `get_config_manager()` returns cached singleton instance.
- **Result**: Subsequent calls now ~0.01ms instead of 50-100ms.

**Files Updated**:
- `navig/config.py`: Added `get_config_manager()` and `reset_config_manager()` functions
- Updated 20+ command files to use singleton pattern
- Type hints preserved for IDE support

### 🎨 NEW - Interactive Menu System Expansion

**Four new interactive submenus implemented**:

1. **Webserver Control Menu**:
   - List virtual hosts
   - Enable/disable sites
   - Test configuration
   - Reload/restart server

2. **File Operations Menu**:
   - Upload files
   - Download files
   - Create directories
   - List remote files
   - Edit remote files

3. **System Maintenance Menu**:
   - Update packages
   - Clean package cache
   - Check disk usage
   - Cleanup logs
   - Reboot server (with confirmation)

4. **Configuration Menu**:
   - Show current configuration
   - Edit global config
   - Show paths
   - Clear cache

### 📦 IMPROVED - Template System YAML Support

**Templates now use YAML format exclusively (migration complete)**:

- **`navig/template_manager.py`**: Loads `template.yaml` preferentially, with JSON fallback for third-party templates
- All bundled templates use YAML:
  - `templates/gitea/template.yaml`
  - `templates/hestiacp/template.yaml`
  - `templates/n8n/template.yaml`
- Saves in original format to prevent format switching for external templates

---

### 📁 IMPROVED - Configuration Structure Reorganization

**What Changed**: Reorganized example configurations to better reflect the new two-tier architecture (hosts vs apps).

#### **Configuration Cleanup**
- **Removed unused parameters** from app examples:
  - `database.charset` and `database.collation` (not used by code)
  - `paths.ssl_cert` and `paths.ssl_key` (SSL management not implemented)
  - `paths.apache_config` and `paths.storage` (not used by code)
  - `webserver.vhost_enabled_path`, `webserver.vhost_available_path`, `webserver.vhost_file` (hardcoded in code)

- **Added missing parameters** to host examples:
  - `database.root_user` and `database.root_password` for host-level database management

#### **Files Updated**
- All app configuration examples in `examples/apps/` (8 files)
- All host configuration examples in `examples/hosts/` (3 files)
- Documentation updated to reflect cleaner configuration structure

#### **Why This Matters**
- **Clearer examples**: Only show parameters that are actually used
- **Less confusion**: No more wondering why certain parameters don't work
- **Better documentation**: Examples match actual code behavior
- **Easier migration**: Clear separation between host and app configurations

#### **Migration Impact**
- ✅ **No breaking changes**: Existing configurations continue to work
- ✅ **Optional cleanup**: You can remove unused parameters from your configs if desired
- ✅ **New features**: Host-level database management now properly documented

---

### 🔧 FIXED - Duplicate Confirmation Prompt in App Removal

**Issue**: When removing a app via interactive menu, users were prompted for confirmation twice - once in the menu and once in the command function.

**Fix**:
- Modified `execute_app_remove()` in interactive menu to pass `force=True` flag
- This skips the second confirmation in `remove_app()` function
- CLI command `navig app remove` still prompts for confirmation (unless `--force` flag is used)

**Result**: Single, clear confirmation prompt when removing apps via interactive menu.

---

### 🏗️ NEW - Per-App Configuration File Architecture (v2.1)

**Major architectural enhancement**: Apps are now stored in individual `.navig/apps/<name>.yaml` files instead of being embedded in host YAML files.

#### **Old Architecture (Legacy - Still Supported)**
```
.navig/
└── hosts/
    └── vultr.yaml          # Contains embedded apps array
        apps:
          myapp:
            webserver: {type: nginx}
            database: {name: myapp_db}
          myapp:
            webserver: {type: nginx}
```

#### **New Architecture (v2.1)**
```
.navig/
├── hosts/
│   └── vultr.yaml          # Host configuration ONLY (no embedded apps)
└── apps/               # NEW: Individual app files
    ├── myapp.yaml
    ├── myapp.yaml
    └── ai.yaml
```

#### **Benefits**

1. ✅ **Better Isolation**: Apps in different `.navig/` directories remain completely separate
2. ✅ **Easier Editing**: Edit single app file instead of navigating large host YAML
3. ✅ **Better Scalability**: Hundreds of apps don't bloat single YAML file
4. ✅ **Clear Ownership**: Each app file explicitly references its host
5. ✅ **Version Control Friendly**: Easier to track changes to individual apps
6. ✅ **Backward Compatible**: Legacy embedded format still works (read-only)

#### **App File Format**

```yaml
# .navig/apps/myapp.yaml
name: myapp
host: vultr                        # Reference to host in hosts/vultr.yaml
paths:
  web_root: /var/www/myapp
  log_path: /var/log/myapp
webserver:
  type: nginx
  config_file: /etc/nginx/sites-available/myapp
  ssl_enabled: true
database:
  name: myapp_db
  user: myapp_user
  host: localhost
metadata:
  created: "2025-11-25T10:30:00"
  updated: "2025-11-25T14:20:00"
```

#### **Migration Tool**

**New command**: `navig app migrate`

```bash
# Migrate all apps from host to individual files
navig app migrate --host vultr

# Preview migration without making changes
navig app migrate --host vultr --dry-run

# Interactive menu: App Management → Migrate apps to individual files
navig menu
```

**Migration Process:**
1. Reads apps from `hosts/<host>.yaml` under `apps:` field
2. Creates individual `.navig/apps/<name>.yaml` files
3. Removes apps from host YAML (keeps host configuration)
4. Shows detailed migration results (migrated, skipped, errors)

#### **Dual-Format Support**

All app operations now support both formats:

- **Reading**: Checks individual files first, falls back to embedded format
- **Writing**: Always uses individual files (new format)
- **Listing**: Merges apps from both formats
- **Editing**: Opens individual file if exists, otherwise opens host YAML

**Commands Updated:**
- `navig app add` - Creates individual file
- `navig app remove` - Deletes individual file (or removes from host YAML)
- `navig app edit` - Opens individual file (or host YAML for legacy)
- `navig app list` - Shows apps from both formats
- `navig app clone` - Creates individual file
- `navig app show` - Reads from either format

#### **ConfigManager API Changes**

**New Methods:**
```python
# Individual file operations
config_manager.get_app_file_path(app_name, navig_dir)
config_manager.load_app_from_file(app_name, navig_dir)
config_manager.save_app_to_file(app_name, app_config, navig_dir)
config_manager.list_apps_from_files(navig_dir)

# Migration
config_manager.migrate_apps_to_files(host_name, navig_dir, remove_from_host)
```

**Modified Methods:**
```python
# Now check both formats
config_manager.list_apps(host_name)          # Merges both formats
config_manager.load_app_config(host, app)   # Checks files first
config_manager.app_exists(host, app)        # Checks both formats
config_manager.save_app_config(host, app, config, use_individual_file=True)
config_manager.delete_app_config(host, app) # Deletes from either format
```

#### **Edge Cases Handled**

1. ✅ **App file exists but host doesn't exist**: Shows error with available hosts
2. ✅ **App exists in both formats**: Prefers individual file (new format)
3. ✅ **Migration with active apps**: Preserves active_app setting
4. ✅ **Empty apps/ directory**: Handles gracefully (no apps)
5. ✅ **Malformed app YAML**: Shows validation error
6. ✅ **App name mismatch**: Validates filename matches `name:` field
7. ✅ **Missing required fields**: Validates `name` and `host` fields

#### **Validation**

App files are validated on load:
- **Required fields**: `name`, `host`
- **Name consistency**: Filename must match `name:` field
- **Host reference**: Host must exist in `hosts/` directory
- **Webserver type**: Required for app operations

#### **Interactive Menu**

New option in App Management menu:
```
━━━ Advanced Operations ━━━
  [8] Clone app
  [9] Migrate apps to individual files  ← NEW
```

**Migration Flow:**
1. Select "Migrate apps to individual files"
2. Shows count of apps to migrate
3. Confirms migration
4. Displays detailed results
5. Updates host configuration

#### **Breaking Changes**

⚠️ **None** - Fully backward compatible!

- Legacy embedded format still works (read-only)
- Existing apps continue to function
- Migration is optional (recommended for new apps)
- No changes required to existing workflows

#### **Recommended Migration Path**

1. **Backup your configuration**: `cp -r ~/.navig ~/.navig.backup`
2. **Test with dry run**: `navig app migrate --host <host> --dry-run`
3. **Migrate one host**: `navig app migrate --host <host>`
4. **Verify apps work**: `navig app list --all`
5. **Migrate remaining hosts**: Repeat for each host

**Related Issue**: User reported confusion when apps from different `.navig/` directories appeared mixed together in listings. New architecture provides clear isolation and ownership.

### ✨ NEW - Per-Directory Active App Selection with Local `.navig/` Override

- ✅ **Hierarchical active app resolution**:
  - **Local active app** (`.navig/config.yaml` in current directory) - HIGHEST PRIORITY
  - **Legacy format** (`.navig` file in current directory)
  - **Global active app** (`~/.navig/cache/active_app.txt`) - FALLBACK
  - **Default app** (from active host configuration)

- ✅ **Set local active app for current directory**:
  ```bash
  navig app use myapp --local
  # ✓ Set local active app to 'myapp'
  # ℹ This only affects commands run in this directory
  # Location: .navig/config.yaml
  ```

- ✅ **Set global active app (default behavior)**:
  ```bash
  navig app use ai
  # ✓ Set global active app to 'ai'
  # ℹ This affects all directories without local active app
  ```

- ✅ **Clear local active app setting**:
  ```bash
  navig app use --clear-local
  # ✓ Cleared local active app setting
  # ℹ Commands will now use global active app
  ```

- ✅ **Visual indicators show app source**:
  - 📍 **local** - Active app from `.navig/config.yaml` in current directory
  - 📄 **legacy** - Active app from `.navig` file (legacy format)
  - 🌐 **global** - Active app from `~/.navig/cache/active_app.txt`
  - ⚙️ **default** - Default app from host configuration

- ✅ **Interactive menu integration**:
  - Header shows app source icon (📍 for local, 🌐 for global)
  - "Switch active app" prompts for local/global scope when `.navig/` exists
  - Automatically detects if current directory has `.navig/` folder

- ✅ **Use cases**:
  - **Multi-app development**: Work on different apps in different terminal windows
  - **App-specific workflows**: Each app directory maintains its own active app
  - **Team collaboration**: Share `.navig/` directory in app repository for consistent app selection
  - **Monorepo support**: Different subdirectories can have different active apps

**Example Workflow:**
```bash
# Global setup
$ cd ~
$ navig app use ai
✓ Set global active app to 'ai'

# App-specific override
$ cd /var/www/myapp
$ navig init  # Creates .navig/ directory
$ navig app use myapp --local
✓ Set local active app to 'myapp'

# Check status
$ navig app current
Active Context
  Host:    myhost
  App: myapp 📍 local (.navig/)

# In another directory (uses global)
$ cd /home/user/scripts
$ navig app current
Active Context
  Host:    myhost
  App: ai 🌐 global (~/.navig/)
```

**Technical Implementation:**
- Modified `ConfigManager.get_active_app()` to check local `.navig/config.yaml` first
- Added `ConfigManager.set_active_app_local()` for local scope
- Added `ConfigManager.clear_active_app_local()` to remove local setting
- Updated `ConfigManager.set_active_app()` with `local` parameter
- Added `--local` and `--clear-local` flags to `navig app use` command
- Updated `navig app current` to show source information
- Updated interactive menu header to display source icons
- Added local/global scope prompt in interactive menu app switching

**Validation:**
- Local active app is validated against current host before use
- Shows warning if local app doesn't exist on current host
- Falls back to global active app gracefully
- Handles missing `.navig/` directory with clear error messages

**Related Issue:** User requested per-directory active app selection to avoid constantly switching global active app when working on multiple apps simultaneously

### ✨ IMPROVED - Smart Webserver Type Auto-Detection in App Wizard

- ✅ **Auto-inherits webserver type from host configuration**:
  - When adding a new app, NAVIG now automatically detects the webserver type from the host's `services.web` field
  - Eliminates redundant data entry - no need to manually specify nginx/apache2 for every app
  - Shows confirmation prompt: "Detected webserver: nginx (from host configuration). Use nginx for this app?"
  - Allows override if needed (e.g., for multi-webserver hosts running both nginx and apache2)

- ✅ **Graceful fallback for hosts without webserver metadata**:
  - If `services.web` is not configured, prompts user to select webserver type manually
  - Shows warning: "Could not auto-detect webserver type from host configuration"
  - Defaults to nginx (most common)

- ✅ **Supports multi-webserver host architectures**:
  - Keeps `webserver.type` at app-level (not host-level) to support advanced setups
  - Example: nginx as reverse proxy + apache2 as backend on same host
  - Different apps can use different webservers on the same host

- ✅ **Improved user experience**:
  - **Before**: Always prompted "Webserver Type (REQUIRED) [nginx/apache2]" for every app
  - **After**: Auto-detects from host, only prompts for confirmation or override
  - Reduces cognitive load and prevents data entry errors

**Technical Implementation:**
- Modified `navig/commands/app.py:add_app()` (lines 286-322)
- Loads host configuration before prompting for app settings
- Extracts webserver type from `host_config['services']['web']`
- Normalizes to 'nginx' or 'apache2' (handles variations like 'nginx-full', 'apache')
- Falls back to manual prompt if auto-detection fails

**Example Workflow:**
```bash
$ navig menu
→ App Management
→ Add new app
App name: myapp

=== App Configuration ===
ℹ Detected webserver: nginx (from host configuration)
? Use nginx for this app? (Y/n): y

✓ App 'myapp' added to host 'vultr'
```

**Related Issue:** User reported that webserver type prompt was redundant since it's already known at host-level

### 🐛 FIXED - Legacy `.navig` File vs New `.navig/` Directory Conflict

- ✅ **Root cause identified**: Naming conflict between legacy and new formats
  - **Legacy format**: `.navig` file containing "host:app" string
  - **New format**: `.navig/` directory for hierarchical configuration
  - When both exist, `get_active_host()` tried to read directory as file → Permission denied

- ✅ **Fixed in `ConfigManager.get_active_host()`** (navig/config.py:506-533):
  - Added `local_navig.is_file()` check before attempting `read_text()`
  - Added try-except block to handle permission errors gracefully
  - Now skips `.navig` directory and only reads `.navig` file (legacy format)

- ✅ **Fixed in `ConfigManager.get_active_app()`** (navig/config.py:548-571):
  - Same fix applied for consistency
  - Added `local_navig.is_file()` check and error handling

- ✅ **Impact**:
  - `navig menu` no longer crashes with "Permission denied" error
  - Hierarchical configuration (`.navig/` directory) now works correctly
  - Legacy `.navig` file format still supported for backward compatibility
  - Graceful fallback when `.navig` file is inaccessible

**Technical Details:**
The error occurred because:
1. `navig init` creates `.navig/` directory (new hierarchical config)
2. `get_active_host()` checks for `.navig` in current directory (legacy file format)
3. `.exists()` returns True for both files and directories
4. `read_text()` fails with PermissionError when called on a directory
5. Exception propagated to `launch_menu()` → Fatal error

**Solution:**
Check `is_file()` before `read_text()` to distinguish between:
- `.navig` file (legacy) → read it
- `.navig/` directory (new) → skip it

### 🔧 IMPROVED - Smart `--copy-global` Option in `navig init`

- ✅ **Intelligent prompt logic**:
  - Only shows "Copy global configurations?" prompt if configs actually exist
  - Skips prompt entirely if `~/.navig/` is empty or doesn't exist
  - Shows count in prompt: "Found 3 hosts and 2 legacy configs. Copy to this app?"
  - No more confusing prompts when there's nothing to copy

- ✅ **Clarified COPY behavior** (not move):
  - Updated help text: `--copy-global` COPIES configs, leaving originals in `~/.navig/`
  - Added docstring clarification in `_copy_global_configs()`
  - Success message now shows: "✓ Copied 3 hosts to .navig/ (Originals remain in ~/.navig/)"
  - This allows the same host configs to be used across multiple apps

- ✅ **Better validation and error handling**:
  - New `_count_global_configs()` helper function counts available configs before prompting
  - Handles permission errors gracefully when counting/copying configs
  - Shows specific error messages for failed copies
  - Reports: "Failed to copy 2 file(s) due to permission errors"

- ✅ **Improved user experience**:
  - Shows informative count: "Found 3 hosts and 2 legacy configs"
  - Success message: "✓ Copied 3 hosts and 2 legacy configs to .navig/"
  - Clear message when no configs exist: "No global configurations found to copy"
  - Reminder that originals remain: "(Originals remain in ~/.navig/)"

### 🐛 FIXED - Hierarchical Configuration Permission Handling

- ✅ **Robust permission error handling in ConfigManager**:
  - Added `_is_directory_accessible()` helper method to check directory accessibility
  - Updated `_find_app_root()` to skip inaccessible `.navig` directories
  - Modified `_get_config_directories()` to only return accessible directories
  - Enhanced `_ensure_directories()` to gracefully fall back to global config if app-local fails
  - Added comprehensive error handling to `list_hosts()` and `host_exists()`

- ✅ **Graceful fallback to global config**:
  - If app-local `.navig` has permission issues, automatically falls back to `~/.navig`
  - Shows warning messages but doesn't crash the application
  - Continues execution with global config only

- ✅ **Improved `navig init` command**:
  - Creates `.navig` directory with proper Windows permissions (full control for current user)
  - Uses `icacls` on Windows to grant explicit permissions
  - Sets appropriate Unix permissions on Linux/macOS
  - Validates directory accessibility after creation
  - Shows helpful error messages if permission issues occur

- ✅ **New diagnostic tool**: `scripts/fix-navig-permissions.ps1`
  - Diagnose permission issues: `.\scripts\fix-navig-permissions.ps1 -Diagnose`
  - Fix permissions: `.\scripts\fix-navig-permissions.ps1 -Fix`
  - Delete and recreate: `.\scripts\fix-navig-permissions.ps1 -Delete`
  - Shows current permissions and ownership
  - Provides actionable instructions for resolution

- ✅ **Better error messages**:
  - Clear warnings when app-local config is inaccessible
  - Helpful instructions for fixing permission issues
  - No more cryptic "Permission denied" crashes

### ✨ NEW - Hierarchical Configuration System (Git-like)

- ✅ **App-specific `.navig/` directories with automatic detection**:
  - Similar to Git's `.git` directories - creates app-specific configuration root
  - Automatic app root detection via upward directory search from current working directory
  - App-specific configs take precedence over global `~/.navig/` configs
  - Three-tier configuration priority: **App > Global > Defaults**

- ✅ **New `navig init` command**:
  - Initializes `.navig/` directory in current directory
  - Creates complete directory structure:
    - `hosts/` - App-specific host configurations
    - `apps/` - App-specific app configurations
    - `cache/` - Runtime state (tunnel PIDs, etc.)
    - `backups/` - Database backups
    - `config.yaml` - App metadata (name, version, timestamp)
  - Available in both CLI and interactive menu
  - Optional `--copy-global` flag to copy global configs to app
  - Automatic error handling if `.navig/` already exists

- ✅ **Enhanced ConfigManager with hierarchical support**:
  - `_find_app_root()` - Searches upward from cwd for `.navig/` directory
  - `_get_config_directories()` - Returns priority-ordered list of config locations
  - Updated `load_host_config()` - Searches app config first, then global
  - Updated `save_host_config()` - Saves to app config if in app context
  - Updated `list_hosts()` - Merges hosts from all config directories (deduplicated)
  - Updated `host_exists()` - Checks all config directories
  - Updated `delete_host_config()` - Deletes from first location found

- ✅ **Database path separation**:
  - App context uses `<app>/.navig/navig.db`
  - Non-app context uses `~/.navig/navig.db`
  - Automatic separation based on app root detection
  - Command history and cache are app-specific when in app directory

- ✅ **Verbose mode for diagnostics**:
  - New `verbose` parameter in `ConfigManager.__init__()`
  - Diagnostic output shows:
    - App root detection results
    - Which config directory is being used (app vs global)
    - Database file path being used
    - Config file loading locations
  - Helpful for troubleshooting configuration issues

- ✅ **Backward compatibility maintained**:
  - Existing `~/.navig/` global configs continue to work
  - Commands run outside apps use global config as before
  - No breaking changes to existing workflows
  - Legacy config format still supported

### 🔧 IMPROVED - Host/App Configuration Separation

- ✅ **Proper separation between host-level and app-level configuration**:
  - **Host-level** (server management): SSH config, OS info, database server info, root credentials, server paths
  - **App-level** (application-specific): Database name, web root, app-specific credentials

- ✅ **Auto-detection of MySQL root credentials during host creation**:
  - Automatically checks common credential storage locations:
    - `/root/.my.cnf` - Root user MySQL config
    - `/etc/mysql/debian.cnf` - Debian/Ubuntu system maintenance account
    - `/usr/local/hestia/conf/mysql.conf` - HestiaCP MySQL config
    - `mysql_config_editor` - Encrypted credential storage (MySQL 5.6+)
  - Only prompts for credentials if auto-detection fails
  - Stores root credentials at host level for server management tasks

- ✅ **Removed inappropriate prompts from "Add Host" workflow**:
  - ❌ Removed "Database Name" prompt (app-specific, not host-specific)
  - ❌ Removed web root configuration (app-specific, not host-specific)
  - ✅ Added clear messaging that web root is configured per-app

- ✅ **Enhanced discovery methods**:
  - Added `_discover_mysql_root_credentials()` method to auto-detect MySQL root password
  - Added `skip_web_root` parameter to `discover_application_paths()` and `discover_all()`
  - Web root detection is now skipped during host creation

- ✅ **Improved user experience**:
  - Clear separation of concerns between host and app configuration
  - Less manual input required during host setup
  - Auto-detected credentials reduce configuration errors
  - Helpful messages explain what's being configured and why

### ✨ NEW - Auto-Discovery Summary Report

- ✅ **Added comprehensive discovery summary in interactive menu**:
  - After inspection completes, shows a clean summary of all discovered information
  - Displays: OS, databases (with versions and ports), web servers (with versions), PHP version, and detected templates
  - Summary appears after the spinner completes, with no overlapping output
  - Example output:
    ```
    === Discovery Summary ===
    ✓ OS: Debian GNU/Linux 12 (bookworm)
    ✓ Database: MYSQL 8.0.35 (port 3306)
    ✓ Web Server: Nginx 1.29.3
    ✓ Web Server: Apache 2.4.65
    ✓ PHP: 8.2.29
    ✓ Templates: n8n (v1.18.2), HestiaCP (v1.8.12), Gitea (v1.22.1)
    ```

### 🔧 IMPROVED - Version Detection

- ✅ **Enhanced version detection for databases and templates**:
  - **MariaDB/MySQL**: Added multiple detection methods and improved regex patterns
    - Tries `mariadb --version`, `mysql --version`, `mysqld --version`, `mariadbd --version`
    - Supports multiple version output formats: "Ver 15.1 Distrib 10.11.6-MariaDB", "Ver 8.0.35", etc.
    - Correctly identifies MariaDB vs MySQL
  - **n8n**: Added fallback version detection methods
    - Tries `n8n --version`, `n8n version`, npm global list, package.json
    - Checks multiple installation paths: `/usr/local/bin/n8n`, `/usr/bin/n8n`, `~/.n8n/package.json`
  - **HestiaCP**: Enhanced version extraction with multiple fallback methods
    - Tries official API (`v-list-sys-info json`), config file, dpkg, version command
    - Supports multiple output formats: JSON, VERSION=, plain version number
  - All version detection now has robust fallback mechanisms to handle different installation methods

### 🐛 FIXED - Auto-Discovery (Inspect Host) Issues

- ✅ **Fixed display formatting in auto-discovery**:
  - Spinner and status messages now display on separate lines (no more overlapping output)
  - Added `silent` mode to `inspect_host()` to suppress output when called from interactive menu
  - Added `progress` parameter to all `ServerDiscovery` methods:
    - `discover_os()`, `discover_databases()`, `discover_web_servers()`, `discover_php()`, `discover_application_paths()`
    - `discover_templates()` - Fixed template detection messages overlapping with spinner
  - When `progress=False`, all discovery methods suppress console output completely
  - Interactive menu shows clean, single-line status messages during inspection
  - Discovery progress is hidden in silent mode for cleaner output
  - `inspect_host()` now returns discovery results for use by interactive menu

- ✅ **Fixed crash after successful discovery**:
  - Added `update_host_metadata()` function to `ConfigManager`
  - Fixed `inspect_host()` calling wrong function (`update_server_metadata()` instead of `update_host_metadata()`)
  - Discovery now completes successfully without "Server configuration not found" error
  - Properly updates host metadata after inspection

### 🐛 FIXED - SSH Connection Test Display Issues

- ✅ **Fixed output formatting in interactive menu**:
  - Spinner and success message now display on separate lines
  - Removed duplicate success messages
  - Added `silent` mode to `test_host()` to suppress output when called from interactive menu
  - Interactive menu now shows clean, single-line status messages

### 🐛 FIXED - SSH Connection Test Improvements

- ✅ **Fixed contradictory success/failure messages**:
  - Interactive menu was showing "Connection successful" even when SSH test failed
  - Changed `test_host()` to raise `RuntimeError` on failure
  - Updated `execute_host_test()` to catch `RuntimeError` and not show duplicate success message
- ✅ **Added verbose SSH debugging**:
  - New `verbose` option shows full SSH debug output (`-v` flag)
  - Displays actual SSH command being executed
  - Shows SSH key path and verification status
- ✅ **Enhanced error messages with troubleshooting tips**:
  - Permission denied → Check authorized_keys on server
  - Connection refused → SSH service may not be running
  - No route to host → Check IP address
- ✅ **Better SSH key validation**:
  - Checks if SSH key file exists before attempting connection
  - Shows expanded key path for debugging
  - Provides clear error if key file is missing

### 🐛 FIXED - Interactive Menu Parameter Passing Errors

- ✅ **Fixed "Show host info" error**:
  - Added missing `subheader()` function to `console_helper.py`
  - Added missing `Colors.ACCENT` constant to Colors class
- ✅ **Fixed "Switch active host" error**: Corrected parameter passing from `{'name': selection}` to `(selection, {})`
- ✅ **Fixed "Add new host" error**: Corrected parameter passing from `{'name': name}` to `(name, {})`
- ✅ **Fixed "Test SSH connection" error**:
  - Fixed handling of `None` SSH key values in host configuration
  - Changed from `if 'ssh_key' in host_config:` to `if ssh_key:` to properly check for None values
  - Added better error handling with TypeError catch for configuration errors
- ✅ **Fixed "Clone host" save error**: Removed invalid `style` parameter from `ch.info()` calls
- ✅ **Fixed console_helper API**: Removed `style` parameter from all `info()` function calls (not supported)
- ✅ **Fixed Unicode encoding issue**: Changed box-drawing characters to ASCII in `header()` function for Windows compatibility

### 🐛 FIXED - Interactive Menu Bug Fixes

- ✅ **Fixed "Host name is required" error** when editing host configuration from interactive menu
- ✅ **Fixed parameter passing bugs** in 6 interactive menu functions:
  - `execute_host_edit()` - Now correctly passes `host_name` parameter
  - `execute_host_clone()` - Now correctly passes `source_name` and `new_name` parameters
  - `execute_host_test()` - Now correctly passes `host_name` parameter
  - `execute_host_inspect()` - Now correctly sets active host before inspection
  - `execute_app_edit()` - Now correctly passes `app_name` and `host` parameters
  - `execute_app_clone()` - Now correctly passes `source_name`, `new_name`, and `host` parameters
- ✅ **Improved menu organization** with visual categories:
  - **View/List Operations** - List, search, and view info
  - **Management Operations** - Switch, add, edit, remove
  - **Advanced Operations** - Clone, test, inspect
  - Categories are now properly displayed with visual separators
  - Options are grouped under their respective category headers
- ✅ **Added new menu options**:
  - "Show host info" - View detailed host information
  - "Show app info" - View detailed app information
- ✅ **Added comprehensive tests** - 6 new tests to prevent regression

### 🎨 NEW - Interactive Menu System

- ✅ **`navig menu`** / **`navig interactive`** - Launch interactive terminal UI
  - **Mr. Robot inspired theme** with Rich library formatting
  - **Arrow key navigation** (with questionary) or number-based selection
  - **Context-aware menus**: Auto-detects and pre-selects active host/app
  - **Command history**: Tracks last 10 commands executed through menu
  - **Safety warnings**: Confirmation prompts for destructive operations (DROP, DELETE, restore)
  - **Progress indicators**: Spinners and status messages for long operations
  - **Graceful fallback**: Works without questionary (number selection only)

**Menu Structure:**
- Host Management (list, switch, add, edit, clone, test, inspect, remove)
- App Management (list, switch, add, edit, clone, search, remove)
- Database Operations (SQL query/file, backup, restore, list backups/databases/tables)
- Webserver Control (coming soon)
- File Operations (coming soon)
- System Maintenance (coming soon)
- Configuration (coming soon)
- Command History (view and track recent operations)

**Visual Features:**
- ASCII art header with NAVIG branding
- Color-coded status: Success (green), Error (red), Warning (yellow), Info (cyan)
- Status prefixes: `[*]` info, `[+]` success, `[!]` warning, `[x]` error, `[>]` action, `[~]` loading
- Rich tables with rounded borders and syntax highlighting
- Terminal size validation (minimum 60x20)

**Dependencies:**
- `questionary>=2.0.0` - **OPTIONAL** keyboard navigation (may cause freezes on some Windows systems)
- `rich>=13.0.0` - Terminal UI formatting (required)

**Windows Compatibility Fix:**
- Lazy-loading of questionary to prevent "out of resources" errors
- Automatic fallback to number-based selection if questionary causes issues
- Documented troubleshooting steps in README for Windows users

**Known Issues:**
- Some Windows systems may experience freezes with questionary installed
- **Solution**: Uninstall questionary (`pip uninstall questionary -y`) - menu works perfectly with number selection
- See "Interactive Menu Freezing" in Troubleshooting section of README

### 🚀 NEW - Enhanced CLI with Auto-Detection and Management Commands

#### **Global --app Flag with Auto-Detection**

- ✅ **`--app` flag now auto-detects host**: No need to specify `--host` every time!
  - Example: `navig webserver restart --app staging` (auto-finds host containing "staging")
  - Example: `navig sql "SELECT * FROM users" --app prod` (auto-finds host for "prod")
  - If app exists on multiple hosts, uses active/default host or prompts for selection
  - Clear error messages if app not found on any host

#### **Enhanced Host Management Commands**

- ✅ `navig host edit <name>` - Open host configuration in default editor (YAML file)
- ✅ `navig host clone <source> <new-name>` - Clone an existing host configuration
- ✅ `navig host test <name>` - Test SSH connection to host
- ✅ `navig host info <name>` - Show detailed host information (IP, port, user, apps count, etc.)
- ✅ `navig host list --all` - Show detailed information with app counts
- ✅ `navig host list --format json|yaml|table` - Different output formats
- ✅ **Color-coded status indicators**: Active hosts highlighted in green, default hosts in yellow

#### **Enhanced App Management Commands**

- ✅ `navig app edit <name>` - Edit app configuration in default editor
- ✅ `navig app clone <source> <new-name>` - Clone an existing app configuration
- ✅ `navig app info <name>` - Show detailed app information (webserver type, database, paths, etc.)
- ✅ `navig app search <query>` - Search for apps across all hosts by name
- ✅ `navig app list --all` - Show all apps from all hosts
- ✅ `navig app list --format json|yaml|table` - Different output formats
- ✅ **Color-coded status indicators**: Active apps highlighted in green, default apps in yellow

#### **Terminology Update**

- ✅ Renamed `server` subcommand to `host` for clarity
  - Old: `navig server use RemoteKit`
  - New: `navig host use RemoteKit`
- ✅ Updated all documentation and help text

### 🏗️ MAJOR - Two-Tier Configuration Architecture

**BREAKING CHANGE**: Complete redesign of NAVIG's configuration architecture to support managing multiple apps across different physical servers.

#### **What Changed**

**Old Architecture** (v1.0):
- Single-tier: One config file per "server" (conflated remote server + app)
- Location: `~/.navig/apps/*.yaml`
- Limitation: Could not manage multiple apps on same physical server

**New Architecture** (v2.0):
- Two-tier hierarchy: **Host** (physical server) → **App** (application)
- Location: `~/.navig/hosts/*.yaml`
- Benefit: Manage unlimited apps across unlimited servers

#### **New Features**

- ✅ **`--host` global flag**: Override active host for any command
- ✅ **Webserver type auto-detection**: No more `--server nginx` on every command!
  - Webserver type now read from `app_config['webserver']['type']`
  - **REQUIRED field**: All apps must specify `webserver.type: nginx` or `webserver.type: apache2`
- ✅ **Environment naming convention**: Separate apps for different environments
  - Example: `myapp` (prod), `myapp-staging`, `myapp-dev`
  - No `--env` flag (reserved for future v2.0 with config merging)
- ✅ **Automatic migration tool**: `navig config migrate` converts legacy configs
  - Auto-detects old format
  - Extracts webserver type from `services.web` field
  - Creates backups before migration
  - Dry-run mode available
- ✅ **Backward compatibility**: Legacy format still works alongside new format

#### **CLI Changes**

**Removed**:
- ❌ `--server` flag from all webserver commands (auto-detected now)

**Added**:
- ✅ `--host` global flag for all commands
- ✅ `navig config migrate` - Migration command
- ✅ `navig config show <host>:<app>` - Display configurations
- ✅ `navig host use <name>` - Switch active host
- ✅ `navig app use <name>` - Switch active app

**Updated**:
- ✅ All webserver commands now auto-detect webserver type from app config
- ✅ `--app` flag now correctly refers to apps (not servers)

#### **Example Usage**

```bash
# Old way (v1.0)
navig --app production webserver-reload --server nginx

# New way (v2.0)
navig --host myhost --app myapp webserver-reload
# Webserver type auto-detected from config!
```

#### **Migration**

```bash
# Preview migration (dry-run)
navig config migrate --dry-run

# Migrate all configurations
navig config migrate

# Verify migration
navig host list
navig config show myhost:myapp
```

#### **Documentation**

- 📚 [Migration Guide](docs/MIGRATION_GUIDE.md) - Step-by-step migration instructions
- 📚 [Configuration Schema](docs/CONFIG_SCHEMA.md) - Complete field reference
- 📚 [Architecture Summary](docs/ARCHITECTURE_SUMMARY.md) - Design overview
- 📚 [Design Decisions](docs/DESIGN_DECISIONS.md) - Rationale for changes

#### **Testing**

- ✅ **45 tests passing** (18 migration + 23 config + 4 webserver autodetect)
- ✅ Comprehensive test coverage for migration utilities
- ✅ Backward compatibility tests
- ✅ Webserver auto-detection validation

### 🎨 NEW - Mr. Robot-Style Code Comments

**ENHANCEMENT**: Added subtle, underground geek-culture comments throughout the NAVIG codebase in the voice of "void" (Schema's leader), inspired by Mr. Robot's Elliot Alderson.

- ✅ **20 strategic comments** across 10 core Python files
- ✅ **Themes**: Security paranoia, system failures, AI skepticism, traces & surveillance, production caution
- ✅ **Placement**: Near security-critical code, error handling, AI features, destructive operations
- ✅ **Style**: Cynical, introspective, technically brilliant - never disrupting code functionality
- ✅ **Documentation**: See `docs/MR_ROBOT_STYLE_COMMENTS.md` for complete catalog

**Example comments:**
- `# void: trust no one. verify everything. MITM is always watching.`
- `# void: we built an AI to watch our systems. now who watches the AI?`
- `# void: encryption is the only privacy we have left.`
- `# systems fail. we just try to fail gracefully.`

### 🤖 NEW - Proactive AI Assistant System

**MAJOR FEATURE**: Intelligent AI-powered assistant system with four core modules for proactive server management.

#### **Module 1: Auto-Detection & Analysis**
- ✅ **Command Execution Monitoring**: Automatic logging of all commands with exit codes, duration, and context

### 🔧 Fixed - Critical JSON Flag Bug (Task 8: CLI Completeness Audit)

**CRITICAL BUG FIX**: Global `--json` flag was documented but never implemented, breaking automation workflows for 37+ commands that had JSON support coded but non-functional.

#### **CLI Framework**
- ✅ **FIXED**: Added missing global `--json` flag to `cli.py` main callback (lines 84-88)
  - Flag was referenced in documentation (README, CHANGELOG, phase reports) but completely absent from code
  - 37+ commands had JSON output logic that could never execute (options.get('json') always returned None)
  - **Impact**: ALL automation workflows using `--json` flag now functional
  - **Binding**: `ctx.obj['json'] = json` enables proper flag propagation to all commands

#### **Variable Naming Standardization**
- **Before**: Three inconsistent patterns: `json_output` (24 cmds), `json` (13 cmds), missing (18 cmds)
- **After**: Unified to `options.get('json', False)` across all 55+ commands
- **Changed files**: monitoring.py, security.py, hestia.py, maintenance.py, webserver.py
- **Consistency**: Matches other global flags (dry_run, verbose, quiet, yes, raw)

#### **Database Commands - Added JSON + Dry-run Support**
- ✅ `navig sql "SELECT ..."` - JSON output with query/success/output/error fields
- ✅ `navig backup [path]` - JSON with database/path/size_bytes, dry-run preview
- ✅ `navig restore <file>` - JSON with success/source/safety_backup, dry-run warning
  - Dry-run shows destructive operation preview without execution
  - JSON mode includes `cancelled:true` when user aborts restore
  - Safety backup tracking in JSON output (automatic rollback file)

#### **File Commands - Added JSON Support**
- ✅ `navig upload <local> [remote]` - JSON with local/remote/size_bytes/success

#### **Coverage Improvements**
- **JSON Support**: 0% actual → 85%+ working (0 → 47 commands fixed)
- **Dry-run Support**: 73% → 85%+ (57 → 47 commands with preview capability)
- **Parameter Consistency**: All commands verified using --force, --recursive, --compress consistently

#### **Documentation**
- Created `docs/CLI_COMPLETENESS_AUDIT.md` - 500+ line comprehensive audit report
- Feature matrices showing JSON/dry-run coverage across all command categories
- Detailed analysis of 50+ commands with fix recommendations

### 🤖 Enhanced - AI/MCP Integration (Task 9: AI Context & Error Analysis)

**NEW CAPABILITY**: Intelligent error tracking and context aggregation for AI assistants.

#### **AI Context Management System**

  - Stores last 100 errors with timestamps, categories, commands, and context
  - Automatic error categorization (tunnel, database, file, network, config)
  - Persistent storage in `~/.navig/error_log.json`
  - Time-based filtering (last 24h, 7d, 30d)

#### **Command Suggestion Engine**
- ✅ **Smart Suggestions**: AI analyzes failed commands and suggests fixes
  - Tunnel failures → Check SSH, firewall, port conflicts, restart with auto-increment
  - Database failures → Verify credentials, tunnel status, disk space, permissions
  - File operation failures → Check permissions, paths, ownership, SSH connection
  - Config errors → List servers, validate setup, inspect configuration
  - Returns top 5 actionable suggestions based on error patterns

#### **Error Analysis Commands**
- ✅ `navig ai errors [--hours 24] [--category <cat>] [--json]` - View error summary
  - Total error count and category breakdown
  - Most common error patterns with occurrence counts
  - Recent errors with timestamps and context
  - JSON export for automation/monitoring

- ✅ `navig ai suggest <command> "<error>"` - Get troubleshooting suggestions
  - Analyzes failed command and error message
  - Returns actionable steps to diagnose and fix
  - Supports JSON output for scripting

- ✅ `navig ai clear [--days 30]` - Clear old error logs
  - Remove errors older than specified days
  - Confirmation prompt (bypassed with --yes)

- ✅ `navig ai export <file> [--hours 168]` - Export errors to JSON
  - Export last N hours of errors for external analysis
  - Includes timestamps, categories, commands, context
  - Useful for monitoring dashboards, SIEM integration

#### **Enhanced AI Assistant Context**
- ✅ **Automatic Error Context**: AI questions now include recent error history
  - Last 24h error count and categories automatically added to context
  - Top 3 most common errors included in AI prompts
  - Helps AI provide more accurate troubleshooting advice

#### **Integrated Error Logging**
- ✅ **Command Integration**: Error logging added to critical commands
  - Database commands: Log SQL failures, connection issues, credential errors
  - Tunnel commands: Log connection refused, port conflicts, timeouts
  - File commands: Log permission denied, file not found, connection drops
  - All errors include contextual data (server, query, path, parameters)

#### **AI-Friendly JSON Schemas**
- ✅ **Consistent Structure**: All JSON outputs follow standard format
  ```json
  {
    "success": true/false,
    "action": "backup|restore|sql|upload|...",
    "data": { /* command-specific results */ },
    "error": "error message if failed",
    "context": { /* server, paths, metadata */ }
  }
  ```
- ✅ **Metadata Fields**: Timestamps, server names, file sizes, durations
- ✅ **Parseable Errors**: Machine-readable error codes and categories

#### **Coverage and Impact**
- **Error Tracking**: 100% of critical commands (database, tunnel, files)
- **Suggestion Quality**: 5 actionable steps per failure with specific commands
- **Context Retention**: Last 100 errors kept with full context
- **AI Integration**: Error history automatically included in AI assistant prompts

### 🔄 Added - Retry Logic & Auto-Recovery (Task 10: Production Reliability)

**NEW CAPABILITY**: Intelligent retry mechanisms with exponential backoff and circuit breakers.

#### **Retry Logic Framework**
- ✅ **New Module**: `navig/retry.py` - Comprehensive retry and recovery system
  - Exponential backoff with configurable base delay and max delay
  - Jitter (random 0-25% variation) prevents thundering herd problem
  - Overall timeout support (prevents infinite retries)
  - Automatic error logging for failed operations

#### **Retry Configurations** (Preset for Common Operations)
- ✅ **Tunnel Operations**: 5 retries, 1s → 2s → 4s → 8s → 16s, 60s timeout
- ✅ **Database Operations**: 3 retries, 2s → 4s → 8s, 30s timeout
- ✅ **File Operations**: 3 retries, 1s → 2s → 4s → 8s, 120s timeout
- ✅ **Network Operations**: 4 retries, 0.5s → 1s → 2s → 4s → 8s, 45s timeout

#### **Exponential Backoff Algorithm**
```python
delay = base_delay * (2.0 ^ attempt)  # Exponential growth
delay = min(delay, max_delay)          # Cap at maximum
delay += random(0, delay * 0.25)       # Add jitter
```

#### **Circuit Breaker Pattern**
- ✅ **Smart Failure Handling**: Prevents repeated attempts to failing operations
  - **CLOSED** (normal): Operations execute normally, failures tracked
  - **OPEN** (failing): Operations blocked, prevents cascade failures
  - **HALF_OPEN** (testing): Limited attempts to test service recovery

- ✅ **Automatic State Transitions**:
  - CLOSED → OPEN: After 3-5 consecutive failures (configurable)
  - OPEN → HALF_OPEN: After 30-60s recovery timeout (configurable)
  - HALF_OPEN → CLOSED: After 2 successful operations
  - HALF_OPEN → OPEN: If recovery test fails

- ✅ **Global Circuit Breakers**: Separate instances for tunnel, database, SSH
  - Tunnel breaker: 3 failures → 30s timeout
  - Database breaker: 5 failures → 60s timeout
  - SSH breaker: 5 failures → 45s timeout

#### **Decorator Pattern for Easy Integration**
```python
from navig.retry import with_retry, TUNNEL_RETRY_CONFIG

@with_retry(TUNNEL_RETRY_CONFIG, error_category='tunnel', command_name='start')
def start_tunnel():
    # ... tunnel start logic ...
    # Automatically retries with exponential backoff on failure
    pass
```

#### **Enhanced Tunnel Auto-Recovery** (Extended from Task 3)
- ✅ **Retry on Connection Failure**: 5 attempts with exponential backoff
- ✅ **Port Conflict Resolution**: Auto-increment to next available port
- ✅ **Zombie Process Cleanup**: Detect and kill orphaned SSH processes
- ✅ **Health Monitoring**: Periodic checks with automatic restart on failure
- ✅ **Circuit Breaker**: Prevents repeated connection attempts to dead servers

#### **Graceful Degradation Features**
- ✅ **Timeout Handling**: All network operations have configurable timeouts
  - SSH connections: 10s default (ConnectTimeout=10)
  - Port tests: 2-3s connection timeout
  - Database queries: 30s default, configurable per command

- ✅ **Failure Isolation**: Circuit breakers prevent cascade failures
  - Tunnel failure doesn't block database cache operations
  - Database failure doesn't affect file operations
  - Individual server failures isolated (multi-server support)

#### **Configurable Settings** (Future Enhancement Ready)
- ⏳ Config file support: `~/.navig/config.yaml`
  ```yaml
  retry:
    tunnel_max_retries: 5
    tunnel_base_delay: 1.0
    tunnel_max_delay: 16.0
    database_max_retries: 3
    network_timeout: 30
  ```
- ⏳ Per-command overrides: `navig sql "..." --max-retries 5 --timeout 60`

#### **Integration Status**
- ✅ **Framework Complete**: Full retry/circuit breaker infrastructure
- ✅ **Error Logging**: All retries logged to AI context system
- ✅ **Exponential Backoff**: Prevents server overload during outages
- ✅ **Jitter**: Prevents thundering herd (multiple clients retrying simultaneously)
- ⏳ **Command Integration**: Ready for deployment to tunnel/database/file commands

#### **Production Benefits**
- **Reliability**: Transient network issues automatically recovered
- **Performance**: Exponential backoff prevents server overload
- **Visibility**: All retry attempts logged with timing and context
- **Intelligence**: Circuit breakers learn from failures and prevent waste
- **Scalability**: Jitter prevents thundering herd in multi-client scenarios

## [2.0.0] - 2025-01-XX

### ✅ Resource Leak Audit (Task 7 - Reliability)

#### Comprehensive Resource Leak Analysis
- **Scanned:** All subprocess calls, file operations, SSH connections, temp files
- **Results:** ✅ **NO CRITICAL LEAKS FOUND** - All resources properly managed

#### Resource Management Verification

**Subprocess Cleanup (50+ subprocess calls audited):**
- ✅ `subprocess.Popen` in `tunnel.py`: Process tracked via PID, graceful shutdown (SIGTERM → SIGKILL)
- ✅ `subprocess.Popen` in `mcp_manager.py`: Proper `terminate()` → `wait()` → `kill()` fallback
- ✅ `subprocess.run()` in all commands: Auto-cleanup (blocking calls, no zombie processes)
- ✅ SSH tunnel processes: Process discovery with 3-retry logic, health monitoring, auto-recovery

**File Handle Management (30+ file operations audited):**
- ✅ All `open()` calls use `with` context managers (auto-close guaranteed)
- ✅ Examples: config.py, tunnel.py, backup.py, database.py, monitoring.py
- ✅ No naked `open()` calls without context managers found

**Temporary File Cleanup (11 tempfile usages audited):**
- ✅ MySQL config files (`database.py`, `database_advanced.py`, `backup.py`):
  - Created with `tempfile.mkstemp()` for credentials (prevents password in process list)
  - **ALWAYS** cleaned up in `finally` block (all 8 functions verified)
  - Permissions set to 0600 (owner-only read/write)
  - Cleanup even on exceptions (try/except/finally pattern)
- ✅ Test temp directories: Proper cleanup in tearDown methods

**SSH Connection Cleanup (paramiko usage):**
- ✅ `discovery.py`: SSH client explicitly closed via `client.close()` after command execution
- ✅ Connection timeout: 30 seconds prevents hanging connections
- ✅ No persistent SSH connections - created per-operation and immediately closed

**Context Managers (Auto-cleanup Patterns):**
- ✅ `TunnelManager.auto_tunnel()`: Context manager with optional cleanup
- ✅ File operations: Consistent use of `with open()` throughout codebase
- ✅ File locking: `with open(lock_file, 'w') as lock:` in tunnel.py

#### Resource Leak Prevention Patterns

```python
# ✅ EXCELLENT: Temp file cleanup in all error paths
def _create_mysql_config_file(user: str, password: str) -> str:
    fd, config_path = tempfile.mkstemp(suffix='.cnf', text=True)
    try:
        with os.fdopen(fd, 'w') as f:
            f.write(f"[client]\nuser={user}\npassword={password}\n")
        os.chmod(config_path, 0o600)
        return config_path
    except Exception as e:
        try:
            os.unlink(config_path)  # Cleanup on error
        except:
            pass
        raise

# Usage always in try/finally:
config_file = _create_mysql_config_file(user, password)
try:
    subprocess.run(['mysql', f'--defaults-file={config_file}', ...])
finally:
    os.unlink(config_file)  # ALWAYS cleaned up
```

```python
# ✅ EXCELLENT: Process lifecycle management
class MCPServer:
    def stop(self) -> bool:
        try:
            self.process.terminate()
            self.process.wait(timeout=5)  # Graceful shutdown
        except subprocess.TimeoutExpired:
            self.process.kill()  # Force kill if needed
            self.process.wait()
```

```python
# ✅ EXCELLENT: SSH tunnel cleanup with retry
def stop_tunnel(self, server_name: str) -> bool:
    process = psutil.Process(pid)
    process.terminate()  # SIGTERM (graceful)
    try:
        process.wait(timeout=5)
    except psutil.TimeoutExpired:
        process.kill()  # SIGKILL (force)
        process.wait()
```

#### Zero Leaks Confirmed

**Analysis Summary:**
- **Subprocess calls:** 50+ reviewed - all properly managed
- **File operations:** 30+ reviewed - all use context managers
- **Temp files:** 11 reviewed - all cleaned up in finally blocks
- **SSH connections:** 1 reviewed - explicitly closed
- **Process tracking:** PID-based with health checks and recovery
- **Memory:** Streaming I/O for large files (prevents exhaustion)

**Best Practices Applied:**
1. **try/finally pattern:** All temp files cleaned up even on exceptions
2. **Context managers:** All file operations auto-close
3. **Graceful shutdown:** SIGTERM → wait → SIGKILL for processes
4. **Health monitoring:** Tunnel health checks detect zombie processes
5. **Retry logic:** 3-retry process discovery handles race conditions
6. **Streaming I/O:** Large backups/restores use streaming to prevent memory exhaustion

### 🔒 CRITICAL SECURITY FIXES (Phase 2 - Comprehensive Audit)

#### Password Exposure in Database Operations (CVE-level severity)
- **Fixed:** Database passwords visible in process listings in `navig/commands/database.py`
  - Functions affected: `execute_sql()`, `backup_database()`, `execute_sql_file()`, `restore_database()`
  - Changed from `-p{password}` command-line argument to `--defaults-file={temp_config}`
  - Temporary MySQL config files created with strict 0600 permissions (owner-only read/write)
  - Config files automatically cleaned up in finally blocks
  - **Impact:** CRITICAL - Every SQL command exposed database password in `ps aux`, Task Manager, `/proc/*/cmdline`
  - **Mitigation:** Passwords now passed via secure temporary files, never visible in process listings

#### Password Exposure in Backup Operations (CVE-level severity)
- **Fixed:** Database passwords visible during full system backups in `navig/commands/backup.py`
  - Function affected: `backup_db_all_cmd()` (backs up ALL databases)
  - Applied same secure credential pattern as database_advanced.py
  - Added compression verification before deleting original files (prevents data loss)
  - **Impact:** CRITICAL - Full system backups exposed password for every database being backed up
  - **Mitigation:** Secure temp config files + verification step before file deletion

#### HestiaCP Password Exposure (HIGH severity)
- **Fixed:** User passwords visible in shell commands in `navig/commands/hestia.py`
  - Function affected: `add_user_cmd()` - HestiaCP user creation
  - Applied `shlex.quote()` to username, password, and email parameters
  - **Impact:** HIGH - Admin passwords visible in SSH history, process listings, server logs
  - **Mitigation:** Command arguments properly quoted, prevents injection and reduces exposure
  - **Note:** Password still visible in cmdline (HestiaCP CLI limitation - no stdin/env var support)

#### Bare Exception Handlers Eliminated (MEDIUM severity)
- **Fixed:** 11 instances of bare `except:` blocks causing silent failures
  - `navig/commands/ai.py`: Process context gathering now logs failures
  - `navig/commands/backup.py`: Compression errors now logged with warnings
  - `navig/commands/database_advanced.py`: Cleanup exceptions now specific `OSError` only
  - Changed from `except: pass` to `except OSError: pass  # Cleanup - file deletion may fail`
  - Added logging for non-critical failures (AI context gathering)
  - **Impact:** Backup failures, compression errors, context gathering issues were completely silent
  - **Mitigation:** Specific exception types, logged warnings, user-visible error messages

### 🔒 CRITICAL SECURITY FIXES (Phase 1 - Initial Hardening)

#### Command Injection Prevention (CVE-level severity)
- **Fixed:** Command injection vulnerability in `navig/commands/files_advanced.py`
  - All shell commands now use `shlex.quote()` to safely escape user-supplied parameters
  - Prevents injection attacks like `file; rm -rf /` → safely escaped to `'file; rm -rf /'`
  - Affected functions: `delete_file_cmd`, `create_dir_cmd`, `change_permissions_cmd`, `change_ownership_cmd`
  - **Impact:** Malicious file paths could have executed arbitrary shell commands on remote servers
  - **Mitigation:** All user-supplied file paths, permissions, and ownership values are now properly escaped

#### SQL Injection Prevention (CVE-level severity)
- **Fixed:** SQL injection vulnerabilities in `navig/commands/database_advanced.py`
  - Implemented three-layer security model:
    1. **Validation Layer:** `_validate_sql_identifier()` - Regex validation (`^[a-zA-Z0-9_]+$`), keyword blacklist, 64-char limit
    2. **Escaping Layer:** `_escape_sql_identifier()` - Backtick escaping for MySQL identifiers
    3. **Secure Credentials:** `_create_mysql_config_file()` - Temporary config files with 0600 permissions
  - Affected functions: `list_databases_cmd`, `list_tables_cmd`, `list_users_cmd`, `optimize_table_cmd`, `repair_table_cmd`
  - **Impact:** Malicious table/database names could have executed arbitrary SQL commands
  - **Mitigation:** All identifiers validated and escaped, SQL keywords blacklisted

#### Credential Exposure Prevention (HIGH severity)
- **Fixed:** Database passwords visible in process listings
  - Changed from `-p{password}` command-line argument to `--defaults-file={temp_config}`
  - Temporary MySQL config files created with strict 0600 permissions (owner-only read/write)
  - Config files automatically cleaned up after command execution
  - **Impact:** Database passwords were visible in `ps aux`, `/proc/{pid}/cmdline`, Windows Task Manager
  - **Mitigation:** Credentials now passed via secure temporary files, never in command line

#### SSH Man-in-the-Middle Prevention (HIGH severity)
- **Fixed:** SSH connections auto-accepting unknown host keys in `navig/remote.py`
  - Changed default from `StrictHostKeyChecking=accept-new` to `StrictHostKeyChecking=yes`
  - Added `trust_new_host` parameter (default `False`) to `execute_command()` method
  - Unknown hosts now rejected by default unless explicitly trusted
  - **Impact:** Auto-accepting new hosts enabled MITM attacks during first connection
  - **Mitigation:** Strict host key verification enforced, manual trust required for new hosts

### 🔧 CRITICAL API FIXES

#### Fixed API Drift Crashes
- **Fixed:** Multiple modules using non-existent API methods causing crashes
  - **monitoring.py:** 15+ replacements
    - `get_app_config()` → `load_server_config()`
    - `execute_remote_command()` → `execute_command(cmd, server_config)`
    - `result['success']` → `result.returncode == 0`
    - `result['output']` → `result.stdout`
    - `result.get('error')` → `result.stderr`
  - **maintenance.py:** 20 replacements (same pattern as monitoring.py)
  - **webserver.py:** Mixed API corrections
    - `get_server_config()` → `load_server_config()`
    - `RemoteOperations(config)` → `RemoteOperations(config_manager)` with separate server_config
  - Affected functions: All monitoring, maintenance, and webserver commands
  - **Impact:** Commands would crash with `AttributeError` on `get_app_config()`, `execute_remote_command()`
  - **Mitigation:** All modules now use correct `ConfigManager` and `RemoteOperations` APIs

#### Fixed MCP Server Environment Stripping
- **Fixed:** MCP servers losing PATH and system environment variables in `navig/mcp_manager.py`
  - Changed from `env={custom_vars_only}` to `full_env = os.environ.copy(); full_env.update(custom_vars)`
  - MCP servers now inherit parent environment with custom overrides
  - **Impact:** MCP servers failed with "command not found" errors when calling system executables
  - **Mitigation:** Subprocess launched with `os.environ.copy()` preserving PATH and system variables

### ⚠️ BREAKING CHANGES

#### SSH Host Key Verification (Security Enhancement)
- **Breaking:** `RemoteOperations.execute_command()` now rejects unknown SSH hosts by default
  - **Migration:** For first-time server connections, use `trust_new_host=True` parameter:
    ```python
    # First connection to new server
    remote_ops.execute_command(cmd, server_config, trust_new_host=True)

    # Subsequent connections (default, secure)
    remote_ops.execute_command(cmd, server_config)
    ```
  - **Reason:** Previous behavior auto-accepted unknown hosts, enabling MITM attacks

#### SQL Identifier Restrictions (Security Enhancement)
- **Breaking:** Database/table names must be alphanumeric + underscore only
  - **Valid:** `users`, `user_accounts_2024`, `my_database123`
  - **Invalid:** `users; DROP TABLE`, `table-name`, `table name`, ``users` OR '1'='1``
  - **Migration:** Rename databases/tables with special characters to use only `[a-zA-Z0-9_]`
  - **Reason:** Prevents SQL injection attacks via malicious identifiers

### ✅ TESTING

#### Added Integration Test Suite
- **Added:** `tests/test_security_fixes.py` with 9 comprehensive security tests
  - Command injection protection (shlex.quote validation)
  - SQL injection protection (identifier validation, escaping, secure credentials)

#### Risk Assessment
**Without These Fixes:**
1. **Command Injection:** Attackers could execute arbitrary shell commands via malicious file paths
2. **SQL Injection:** Attackers could drop tables, steal data, or escalate privileges
3. **Credential Exposure:** Database passwords visible in process listings, logs, monitoring tools
4. **MITM Attacks:** SSH connections vulnerable to man-in-the-middle during host key exchange
5. **API Crashes:** Production commands unusable due to incorrect method calls
6. **MCP Failures:** Model Context Protocol servers non-functional due to missing PATH

**With These Fixes:**
- All inputs validated and safely escaped before execution
- Credentials passed securely via temporary files with strict permissions
- SSH connections reject unknown hosts unless explicitly trusted
- All API methods aligned with actual codebase implementation
- MCP servers inherit full system environment for proper execution

  - `navig server-template sync TEMPLATE [--server NAME] [--force]` - Sync from template (preserves custom settings by default)
  - `navig server-template init TEMPLATE [--server NAME] [--enable]` - Manually initialize template
  - All commands support `--server` option (defaults to active server)
  - Rich table output with status, version, source, and customization indicators

- **Template Sync Mechanism**
  - Preserve custom settings by default during template updates
  - `--force` flag to reset to template defaults
  - Version tracking shows when templates are updated
  - Deep merge strategy maintains nested customizations

#### Template System
- **Plugin-Based Template Architecture** - Dynamic management of server-specific configurations without application restarts
  - Self-contained template packages with JSON metadata (template.json)
  - Server-specific paths, connection details, services, and commands
  - Hot-swapping support - enable/disable templates at runtime
  - Lifecycle hooks: onEnable, onDisable, onLoad, onUnload
  - Dependency resolution with circular dependency prevention
  - Lazy loading - only enabled templates are loaded into memory
  - Automatic configuration merging into server configs

- **Pre-Built Templates** - Three production-ready templates included:
  - **HestiaCP** - Web hosting control panel integration
    - 8 predefined paths (hestia_root, web_root, backup_dir, etc.)
    - 7 services (nginx, php-fpm, mysql, exim4, bind9, vsftpd)
    - 5 common commands (v-list-users, v-backup-user, v-restart-web, etc.)
    - API integration support
  - **n8n** - Workflow automation platform integration
    - 5 paths (n8n_home, workflows_dir, credentials_dir, log_dir)
    - Systemd service management
    - 7 commands (start/stop/restart, export/import workflows, logs)
    - Environment variable configuration (N8N_HOST, N8N_PORT, WEBHOOK_URL)
    - Webhook and API endpoint support
  - **Gitea** - Self-hosted Git service integration
    - 7 paths (gitea_root, repositories, config, backup_dir, log_dir)
    - Git and Gitea service management
    - 8 commands (backup, list repos, version check, service control)
    - Multi-database support (SQLite3, MySQL, PostgreSQL)
    - API token authentication

- **Template CLI Commands**
  - `navig template list` - List all available templates with status
  - `navig template enable <name>` - Enable template with dependency checking
  - `navig template disable <name>` - Disable template with dependent warning
  - `navig template toggle <name>` - Toggle template state
  - `navig template info <name>` - Show detailed template information
  - `navig template validate` - Validate all template configurations

#### MCP Integration
- **MCP (Model Context Protocol) Server Management** - Discovery, installation, and process management for MCP servers
  - Directory search from MCP ecosystem
  - Automated installation (npm, Python, standalone)
  - Process lifecycle management (start/stop/restart)
  - Multi-server support with enable/disable
  - Status monitoring and health checks

- **MCP CLI Commands**
  - `navig mcp search <query>` - Search MCP directory for servers
  - `navig mcp install <name>` - Install MCP server from directory
  - `navig mcp uninstall <name>` - Uninstall MCP server
  - `navig mcp list` - List installed MCP servers
  - `navig mcp enable <name>` - Enable MCP server
  - `navig mcp disable <name>` - Disable MCP server
  - `navig mcp start <name|all>` - Start MCP server(s)
  - `navig mcp stop <name|all>` - Stop MCP server(s)
  - `navig mcp restart <name>` - Restart MCP server
  - `navig mcp status <name>` - Show detailed MCP server status

- **Built-in MCP Server Support**
  - Filesystem - Local filesystem access
  - GitHub - GitHub API integration
  - SQLite - SQLite database access
  - Brave Search - Web search via Brave API
