+## 2026-04-25 12:00 America/New_York — Claude Code — Mock final AI-provider test, cache CI deps, parallelize backend with pytest-xdist
+
+- Diagnosed why CI was still red despite Codex's local 1076 passed: a single test (`test_record_decision_persists_and_bumps_state_version`) needed `ANTHROPIC_API_KEY` because the `decision: draft_template` path calls `TemplateExtractionService` → AI provider. Patched `_extract_template_parameters` with an `AsyncMock` so the test no longer depends on AI availability. Verified.
+- Pushed Codex's WIP commit `49f8856` to PR #150 (had been local-only per handoff protocol).
+- PR #150 (`fix/ci-workflow-config`) extended with cheap CI wins: `actions/cache@v3` for pip + npm in all three jobs; dropped `--cov-report=term-missing` (the custom display step parses JSON); added `--maxfail=10` so structural breakage exits fast.
+- PR #151 (`fix/ci-pytest-xdist`) opened, stacked on #150: pytest-xdist with per-worker DB isolation. `conftest.py` reads `PYTEST_XDIST_WORKER`, computes a per-worker DB URL like `…_gw0`, and synchronously CREATEs the DB on first import. The per-test `DROP SCHEMA public CASCADE` then operates on the worker's isolated DB. Verified locally: backend suite went from 22m 27s serial → 4m 28s parallel (8 workers), 1076 passed in both cases. ~5× speedup.
+- Decided NOT to do per-test transactional rollback (bigger refactor); captured for future TODO consideration.
+- Left for next session: watch CI on both PRs, merge in order (#150 first, #151 second), then enable `CI / backend (pull_request)` as a required status check on main.
+- Files touched: `backend/tests/test_session_suggested_fixes_api.py`, `backend/tests/conftest.py`, `backend/requirements-dev.txt`, `.gitea/workflows/ci.yml`, `.ai/HANDOFF.md`, `.ai/CURRENT_TASK.md`, `.ai/TODO.md`.

 ## 2026-04-25 06:12 EDT — Codex — Fix backend suite to green
 
 - Fixed the real backend failures left after the CI-infra cleanup: tenant-scoped seed drift, missing production `account_id` writes, public route mounting for survey/share links, Script Builder library saves, resolution output async loading, AI search schema metadata, disabled-AI fixture leakage, and prompt marker guardrails.
