 ## Session Log
 
+- **2026-04-24 Codex (retrieval boundary deployed + project_id metadata tranche)** Merged `codex/audit-improvements-foundation` to `main` as `f44a211` and pushed to Dalidou Gitea. Took pre-deploy runtime backup `/srv/storage/atocore/backups/snapshots/20260424T144810Z` (DB + registry, no Chroma). Deployed via `papa@dalidou` canonical `deploy/dalidou/deploy.sh`; live `/health` reports build_sha `f44a2114970008a7eec4e7fc2860c8f072914e38`, build_time `2026-04-24T14:48:44Z`, status ok. Post-deploy retrieval harness: 20 fixtures, 19 pass, 0 blocking failures, 1 known issue (`p04-constraints`). The former blocker `p05-broad-status-no-atomizer` now passes. Manual p05 `context-build "current status"` spot check shows no p04/Atomizer source bleed in retrieved chunks. Started follow-up branch `codex/project-id-metadata-retrieval`: registered-project ingestion now writes explicit `project_id` into DB chunk metadata and Chroma vector metadata; retrieval prefers exact `project_id` when present and keeps path/tag matching as legacy fallback; added dry-run-by-default `scripts/backfill_chunk_project_ids.py` to backfill SQLite + Chroma metadata; added tests for project-id ingestion, registered refresh propagation, exact project-id retrieval, and collision fallback. Verified targeted suite (`test_ingestion.py`, `test_project_registry.py`, `test_retrieval.py`): 36 passed. Verified full suite: 556 passed in 72.44s. Branch not merged or deployed yet.

 - **2026-04-24 Codex (audit improvements foundation)** Started implementation of the audit recommendations on branch `codex/audit-improvements-foundation` from `origin/main@c53e61e`. First tranche: registry-aware project-scoped retrieval filtering (`ATOCORE_RANK_PROJECT_SCOPE_FILTER`, widened candidate pull before filtering), eval harness known-issue lane, two p05 project-bleed fixtures, `scripts/live_status.py`, README/current-state/master-plan status refresh. Verified `pytest -q`: 550 passed in 67.11s. Live retrieval harness against undeployed production: 20 fixtures, 18 pass, 1 known issue (`p04-constraints` Zerodur/1.2 content gap), 1 blocking guard (`p05-broad-status-no-atomizer`) still failing because production has not yet deployed the retrieval filter and currently pulls `P04-GigaBIT-M1-KB-design` into broad p05 status context. Live dashboard refresh: health ok, build `2b86543`, docs 1748, chunks/vectors 33253, interactions 948, active memories 289, candidates 0, project_state total 128. Noted count discrepancy: dashboard memories.active=289 while integrity active_memory_count=951; schedule reconciliation in a follow-up.
 
 - **2026-04-24 Codex (independent-audit hardening)** Applied the Opus independent audit's fast follow-ups before merge/deploy. Closed the two P1s by making project-scope ownership path/tag-based only, adding path-segment/tag-exact matching to avoid short-alias substring collisions, and keeping title/heading text out of provenance decisions. Added regression tests for title poisoning, substring collision, and unknown-project fallback. Added retrieval log fields `raw_results_count`, `post_filter_count`, `post_filter_dropped`, and `underfilled`. Added retrieval-eval run metadata (`generated_at`, `base_url`, `/health`) and `live_status.py` auth-token/status support. README now documents the ranking knobs and clarifies that the hard scope filter and soft project match boost are separate controls. Verified `pytest -q`: 553 passed in 66.07s. Live production remains expected-predeploy: 20 fixtures, 18 pass, 1 known content gap, 1 blocking p05 bleed guard. Latest live dashboard: build `2b86543`, docs 1748, chunks/vectors 33253, interactions 950, active memories 290, candidates 0, project_state total 128.
