**Date**: 2026-06-29 01:20
**Commit**: 7a5a48f (pushed to Forgejo)
**Tests**: 47/47 T03 tests pass, 103/103 full suite pass
**Coverage**: 85.92% for plugin modules (target: 85% ✅)
**Migration**: 0003_plugin_system.py applied (plugins + plugin_migrations tables)

### Files Created (12 new)
- app/plugins/__init__.py, manifest.py, base.py, registry.py, migration_runner.py
- app/plugins/builtins/__init__.py, test_sample.py, migrations/0001_test_plugin.sql, migrations/0001_bad_migration.sql

- app/models/__init__.py, app/routes/__init__.py, app/schemas/__init__.py, app/services/__init__.py
- tests/conftest.py (plugin tables in TRUNCATE list)

### Bugs Fixed by Subagent
1. Unterminated f-string in registry.py
2. Migration runner DB connection visibility (now uses session's own connection)
3. Route unregistration by path match (FastAPI wraps routes differently)
4. Dollar-quote SQL splitting (flush after closing $$)
5. AC11 assertion type (dict vs string for HTTPException detail)

### Verification (Orchestrator Independent)
- pytest tests/test_plugins.py -v: 47/47 PASS
- pytest tests/ -v: 103/103 PASS (zero regressions)
- Coverage: 85.92% (manifest 100%, base 88%, registry 88%, migration_runner 79%)
- Migration 0003 applied via alembic upgrade head
- No forbidden patterns found

**Commit**: 14bd4e3 (pushed to Forgejo)
**Tests**: 238/238 full suite pass (30 AC + 105 coverage + 103 existing)
**Coverage**: 84.12% for T09 modules (target: 80% ✅)
**Migration**: 0004_ai_workflows.py applied (5 tables with RLS)

### Files Modified (7)
- app/models/__init__.py, app/routes/__init__.py, app/schemas/__init__.py, app/services/__init__.py
- app/main.py (added ai_copilot + workflows routers)
- tests/conftest.py (added new tables to TRUNCATE + model imports)
- app/core/event_bus.py (added workflow event handler registration)

### Bugs Fixed
1. MissingGreenlet on async lazy-load of updated_at/created_at — fixed with _safe_iso() and _get_attr() helpers
2. _message_to_dict in ai_copilot_service.py — patched by orchestrator (m.created_at.isoformat() → _safe_iso(_get_attr(m, "created_at")))

### Verification (Orchestrator Independent)
- pytest tests/: 238/238 PASS (zero regressions)
- Migration 0004 applied via alembic upgrade head
- RLS policies on all 5 new tables (ai_conversations, ai_messages, workflows, workflow_instances, workflow_step_history)
- No forbidden patterns (.test TLD, SET LOCAL, raise HTTPException in middleware, POST without status_code)
- POST action endpoints (query/execute/advance/cancel) correctly use 200 default
- POST creation endpoints (workflows, instances) correctly use 201
