# Dependency graph
requires:
  - phase: 02-action-registry/02-02
    provides: BaseController, CheckController, ReweaveController, GraphController, ExportController, VectorController, UpgradeController + action registration patterns

provides:
  - CreateController wrapping all 4 CreateService methods (create_note, create_reference, create_task, create_batch)
  - UpdateController wrapping update, archive, supersede
  - QueryController wrapping all 10 QueryService methods
  - SessionController wrapping all 9 SessionService methods
  - IngestController wrapping list_providers, ingest_text, ingest_file, ingest_url
  - WorkflowController wrapping WorkflowService static methods
  - InitController wrapping InitService static methods
  - controllers/__init__.py re-exporting all 14 controller classes
  - Integration tests for CreateController, QueryController, SessionController

affects: [02-action-registry/02-04, registry-layer, action-registry]

# Tech tracking
tech-stack:
  added: []
  patterns:
    - "Thin controller wrappers: each method uses lazy local service import per-call"
    - "Static-method services (Workflow, Init) still wrapped in BaseController for consistency"
    - "Integration tests follow vault fixture pattern from conftest.py"
    - "Task ID prefix is TASK- not TSK- (discovered via test failure)"

key-files:
  created:
    - src/ztlctl/controllers/create.py

  modified:
    - src/ztlctl/controllers/__init__.py

key-decisions:
  - "WorkflowController and InitController extend BaseController for consistency even though their services use static methods"
  - "InitController named init_ctrl.py to avoid shadowing __init__.py"
  - "Task prefix discovered to be TASK- not TSK- — fixed test assertion during RED phase"

patterns-established:
  - "All controllers: lazy local service imports inside each method body (no module-level service imports)"
  - "Static-method services (Workflow, Init): controller passes explicit path/vault args, does not rely on self._vault for those methods"

# Phase 02 Plan 03: Complete Controller Layer Summary

**7 controllers (Create, Update, Query, Session, Ingest, Workflow, Init) complete the controller layer with lazy imports, mypy-strict, and 51 passing integration tests**

## Performance

- **Duration:** 4 min
- **Started:** 2026-03-19T21:38:48Z
- **Completed:** 2026-03-19T21:42:49Z
- **Tasks:** 2
- **Files modified:** 11

## Accomplishments

- CreateController wraps all 4 CreateService methods with exact signatures (create_note, create_reference, create_task, create_batch)
- QueryController wraps all 10 QueryService methods including topic_packet, draft_from_topic, vault_review
- SessionController wraps all 9 SessionService methods including context, brief, extract_decision
- UpdateController, IngestController, WorkflowController, and InitController complete the service coverage
- controllers/__init__.py now re-exports all 14 controller classes
- Integration tests for Create, Query, and Session controllers all pass (51 controller tests total)

## Task Commits

Each task was committed atomically:

1. **Task 1: Write-heavy and complex controllers (Create, Update, Query, Session, Ingest)** - `708482e` (feat)
2. **Task 2: Custom_presentation controllers (Workflow, Init) and integration tests** - `63dbe44` (feat)

**Plan metadata:** (to be updated after state commit)

## Files Created/Modified

- `src/ztlctl/controllers/create.py` - CreateController wrapping CreateService (4 methods)
- `src/ztlctl/controllers/update.py` - UpdateController wrapping UpdateService (3 methods)
- `src/ztlctl/controllers/query.py` - QueryController wrapping QueryService (10 methods)
- `src/ztlctl/controllers/session.py` - SessionController wrapping SessionService (9 methods)
- `src/ztlctl/controllers/ingest.py` - IngestController wrapping IngestService (4 methods)
- `src/ztlctl/controllers/workflow.py` - WorkflowController wrapping WorkflowService static methods
- `src/ztlctl/controllers/init_ctrl.py` - InitController wrapping InitService static methods
- `src/ztlctl/controllers/__init__.py` - Updated to re-export all 14 controller classes
- `tests/controllers/test_create.py` - 10 integration tests for CreateController
- `tests/controllers/test_query.py` - 15 integration tests for QueryController
- `tests/controllers/test_session.py` - 10 integration tests for SessionController

## Decisions Made

- WorkflowController and InitController extend BaseController for consistency even though their underlying services use @staticmethod
- InitController is named `init_ctrl.py` to avoid Python import shadowing of `__init__.py`
- Task ID prefix is `TASK-` not `TSK-` — discovered via test failure and corrected

## Deviations from Plan

**1. [Rule 1 - Bug] Incorrect task ID prefix in test assertion**
- **Found during:** Task 2 (TDD RED phase)
- **Issue:** Test asserted `result.data["id"].startswith("TSK-")` but actual prefix is `TASK-`
- **Fix:** Updated assertion to `startswith("TASK-")`
- **Files modified:** tests/controllers/test_create.py
- **Verification:** Tests pass with correct prefix
- **Committed in:** `63dbe44` (Task 2 commit)

---

**Total deviations:** 1 auto-fixed (Rule 1 - Bug in test assertion)
**Impact on plan:** Minor test assertion correction only. No scope creep.

## Issues Encountered

None beyond the task ID prefix fix above.

## Next Phase Readiness

- All 13 controllers (+ BaseController = 14 exported) are ready for the registry layer (Plan 04)
- controllers/__init__.py is the single import surface for the registry layer
- 1632 tests passing (51 new controller tests), mypy strict clean, ruff clean

## Self-Check: PASSED

All created files confirmed present. All task commits (708482e, 63dbe44) confirmed in git history.
