Now I have everything I need. Let me write the review.

## Review: Linus Torvalds — Memory Storage Layer

I've read the PRD, the task list, the full diff, and run the tests. Let me cut the crap and tell you what's actually here.

### What Was Done

The branch delivers **one out of seven task groups**: Task 1.0 (Memory Storage Layer). The `memory.py` module and its tests are solid — clean SQLite schema, FTS5 triggers, proper sanitization, FIFO pruning, and a `load_memory_for_injection()` function. 28 tests, all passing. The code is straightforward, no over-engineering. Good.

There are also unrelated TUI style changes (hardcoded hex colors → Textual semantic tokens) and a TUI test fix. These are fine changes but have nothing to do with the PRD.

### What Was NOT Done

This is where it falls apart. The PRD has six functional requirements. Let's count:

- **FR-1 (Memory Storage)**: ✅ Done
- **FR-2 (Capture Hooks)**: ❌ Not implemented. No orchestrator integration. No post-phase capture. No failure capture. (Tasks 3.0)
- **FR-3 (Memory Injection)**: ❌ The `load_memory_for_injection()` function exists but is **never called anywhere**. Not wired into `orchestrator.py`, not wired into `router.py`. (Tasks 4.0)
- **FR-4 (MemoryConfig)**: ❌ No `MemoryConfig` dataclass in `config.py`. No YAML parsing. No `memory.enabled` toggle. (Tasks 2.0)
- **FR-5 (CLI Commands)**: ❌ No `colonyos memory` CLI group. No list/search/delete/clear/stats commands. (Tasks 5.0)
- **FR-6 (Learnings Coexistence)**: ❌ Not wired — trivially satisfied since nothing was changed, but the learn phase doesn't write to both systems as specified.
- **Gitignore**: ❌ `memory.db` not added to `.gitignore`.
- **Integration tests**: ❌ None (Tasks 7.0)

The task file shows **zero tasks checked off**. Every single checkbox is still `- [ ]`.

### Code Quality of What IS There

The `memory.py` code itself is actually decent. A few observations:

1. **No `close()` in normal flow** — `MemoryStore` opens a connection in `__init__` but there's no context manager (`__enter__`/`__exit__`). Every caller has to remember to call `.close()`. The tests don't even close most stores (the `store` fixture never calls close). This will leak file descriptors in production.

2. **The pruning happens AFTER commit** — `add_memory()` commits the insert, then calls `_prune_if_needed()` which does another query and delete. This should be a single transaction, not two separate commits. If the process dies between them, you exceed the cap.

3. **FTS5 escaping is minimal** — `safe_keyword = keyword.replace('"', '""')` only handles double quotes. FTS5 has other special characters (`*`, `NEAR`, `AND`, `OR`, `NOT`, parentheses). A user searching for `"foo AND bar"` will get FTS5 syntax, not a literal search. This is a latent bug.

4. **The TUI changes are unrelated** — the styles.py refactor and test_setup.py changes have nothing to do with memory. This is exactly the kind of drive-by cleanup that makes `git blame` useless and reviews harder. Ship them separately.

VERDICT: request-changes

FINDINGS:
- [cOS_tasks/...tasks...md]: All 7 task groups remain unchecked — only task 1.0 has any implementation
- [src/colonyos/config.py]: FR-4 (MemoryConfig) not implemented — no configuration dataclass, no YAML parsing, no enabled toggle
- [src/colonyos/orchestrator.py]: FR-2 (capture hooks) and FR-3 (injection) not wired — memory is never captured or injected
- [src/colonyos/cli.py]: FR-5 (CLI commands) not implemented — no `colonyos memory` command group
- [src/colonyos/router.py]: FR-3 memory injection into direct-agent prompts not implemented
- [src/colonyos/memory.py]: MemoryStore lacks `__enter__`/`__exit__` context manager — will leak file descriptors
- [src/colonyos/memory.py]: `add_memory()` pruning runs as a separate transaction after the insert commit — should be atomic
- [src/colonyos/memory.py]: FTS5 keyword escaping only handles double quotes, not other FTS5 operators (AND, OR, NOT, *, NEAR)
- [src/colonyos/tui/styles.py]: Unrelated TUI color refactor bundled into a memory feature branch — ship separately
- [.gitignore]: `memory.db` not added to gitignore as required by PRD

SYNTHESIS:
This branch delivers roughly 15% of the PRD — the storage layer and nothing else. The storage code itself is competently written, the data structures are right, the tests are thorough. But a storage layer that nothing reads from or writes to is a library without a program. There's no config integration, no orchestrator hooks, no CLI, no gitignore update. The feature is inert — if you merged this, ColonyOS would behave identically to before. The unrelated TUI style changes muddying the diff is the cherry on top. Finish the remaining six task groups, split out the TUI cleanup into its own commit, and come back when the memory system actually *does something*.
