docs(planning): V1 Completion Plan — Codex sign-off (third round)

Codex's third-round audit closed the remaining five open questions
with concrete file:line resolutions, patched inline in the plan:

- F-7 (P1): graduation stack is partially built — graduated_to_entity_id
  at database.py:143-146, graduated memory status, promote preserves
  original at service.py:354-356, tests at test_engineering_v1_phase5.py.
  Gaps: missing direct POST /memory/{id}/graduate route; spec's
  knowledge -> Fact mismatches ontology (no fact type). Reconcile to
  parameter or similar. V1-E 2 days -> 3-4 days.

- Q-5 / V1-D (P2): renderer reads wall-clock in _footer at mirror.py:320.
  Fix is injecting regenerated timestamp + checksum as renderer inputs,
  sorting DB iteration, removing dict ordering deps. Render code must
  not call wall-clock directly.

- project vs project_id (P3): doc note only, no storage rename.

- Total estimate: 17.5-19.5 focused days (calendar buffer on top).

- Release notes must NOT canonize "Minions" as a V2 name. Use neutral
  "queued background processing / async workers" wording.

Sign-off from Codex: "with those edits, I'd sign off on the five
questions. The only non-architectural uncertainty left in the plan is
scheduling discipline against the current Now list; that does not
block V1-0 once the soak window and memory-density gate clear."

Plan frozen. V1-0 starts after pipeline soak (~2026-04-26) and the
100-active-memory density gate clear.

 ## Recent Decisions
 
+- **2026-04-22** **Engineering V1 Completion Plan — Codex sign-off (third round)**. Codex's third-round audit closed the remaining five open questions with concrete resolutions, patched inline in `docs/plans/engineering-v1-completion-plan.md`: (1) F-7 row rewritten with ground truth — schema + preserve-original + test coverage already exist (`graduated_to_entity_id` at `database.py:143-146`, `graduated` status in memory service, promote hook at `service.py:354-356,389-451`, tests at `test_engineering_v1_phase5.py:67-90`); **real gaps** are missing direct `POST /memory/{id}/graduate` route and spec's `knowledge→Fact` mismatch (no `fact` entity type exists; reconcile to `parameter` or similar); V1-E 2 → **3–4 days**; (2) Q-5 determinism reframed — don't stabilize the call to `datetime.now()`, inject regenerated timestamp + checksum as renderer inputs, remove DB iteration ordering dependencies; V1-D scope updated; (3) `project` vs `project_id` — doc note only, no rename, resolved; (4) total estimate 16.5–17.5 → **17.5–19.5 focused days** with calendar buffer on top; (5) "Minions" must not be canonized in D-3 release notes — neutral wording ("queued background processing / async workers") only. **Agreement reached**: Claude + Codex + Antoine aligned. V1-0 is ready to start once the current pipeline soak window ends (~2026-04-26) and the 100-memory density target is hit. *Patched by:* Codex. *Signed off by:* Codex ("with those edits, I'd sign off on the five questions"). *Accepted by:* Antoine. *Executor (V1-0 onwards):* Claude.
 - **2026-04-22** **Engineering V1 Completion Plan revised per Codex second-round file-level audit** — three findings folded in, all with exact file:line refs from Codex: (1) F-1 downgraded from ✅ to 🟡 — `extractor_version` and `canonical_home` missing from `Entity` dataclass and `entities` table per `engineering-v1-acceptance.md:45`; V1-0 scope now adds both fields via additive migration + doc note that `project` IS `project_id` per "fields equivalent to" spec wording; (2) F-2 replaced with ground-truth per-query status: 9 of 20 v1-required queries done (Q-004/Q-005/Q-006/Q-008/Q-009/Q-011/Q-013/Q-016/Q-017), 1 partial (Q-001 needs subsystem-scoped variant), 10 missing (Q-002/003/007/010/012/014/018/019/020); V1-A scope shrank to Q-001 shape fix + Q-6 integration (pillar queries already implemented); V1-C closes the 8 remaining new queries + Q-020 deferred to V1-D; (3) F-5 reframed — generic `conflicts` + `conflict_members` schema already present at `database.py:190`, no migration needed; divergence is detector body (per-type dispatch needs generalization) + routes (`/admin/conflicts/*` needs `/conflicts/*` alias). Total revised to 16.5–17.5 days, ~60 tests. Plan: `docs/plans/engineering-v1-completion-plan.md` at commit `ce3a878` (Codex pulled clean). Three of Codex's eight open questions now answered; remaining: F-7 graduation depth, mirror determinism, `project` rename question, velocity calibration, minions naming. *Proposed by:* Claude. *Reviewed by:* Codex (two rounds).
 - **2026-04-22** **Engineering V1 Completion Plan revised per Codex first-round review** — original six-phase order (queries → ingest → mirror → graduation → provenance → ops) rejected by Codex as backward: provenance-at-write (F-8) and conflict-detection hooks (F-5 minimal) must precede any phase that writes active entities. Revised to seven phases: V1-0 write-time invariants (F-8 + F-5 hooks + F-1 audit) as hard prerequisite, V1-A minimum query slice proving the model, V1-B ingest, V1-C full query catalog, V1-D mirror, V1-E graduation, V1-F full F-5 spec + ops + docs. Also softened "parallel with Now list" — real collision points listed explicitly; schedule shifted ~4 weeks to reflect that V1-0 cannot start during pipeline soak. Withdrew the "50–70% built" global framing in favor of the per-criterion gap table. Workspace sync note added: Codex's Playground workspace can't see the plan file; canonical dev tree is Windows `C:\Users\antoi\ATOCore`. Plan: `docs/plans/engineering-v1-completion-plan.md`. Awaiting Codex file-level audit once workspace syncs. *Proposed by:* Claude. *First-round review by:* Codex.
 - **2026-04-22** gbrain-inspired "Phase 8 Minions + typed edges" plan **rejected as packaged** — wrong sequencing (leapfrogged `master-plan-status.md` Now list), wrong predicate set (6 vs V1's 17), wrong canonical boundary (edges-on-wikilinks instead of typed entities+relationships per `memory-vs-entities.md`). Mechanic (durable jobs + typed graph) deferred to V1 home. Record: `docs/decisions/2026-04-22-gbrain-plan-rejection.md`. *Proposed by:* Claude. *Reviewed/rejected by:* Codex. *Ratified by:* Antoine.

 ## Session Log
 
+- **2026-04-22 Codex (late night)** Third-round audit closed the remaining five open questions. Patched `docs/plans/engineering-v1-completion-plan.md` inline (no commit by Codex). **F-7 finding (P1):** graduation stack is partially built — `_graduation_prompt.py`, `scripts/graduate_memories.py`, `database.py:143-146` (`graduated_to_entity_id`), memory `graduated` status, promote-preserves-original at `service.py:354-356,389-451`, tests at `test_engineering_v1_phase5.py:67-90` all exist. Real gaps: no direct `POST /memory/{id}/graduate` route at `routes.py:756`; spec's `knowledge→Fact` doesn't match ontology (`service.py:16` has no `fact` type — reconcile to `parameter` or similar). V1-E estimate 2 → 3–4 days. **Q-5 finding (P2):** "stabilize timestamp" insufficient — renderer reads wall-clock in `_footer()` at `mirror.py:320`; fix is inject regenerated timestamp + checksum as renderer inputs + sort DB iteration + remove dict ordering deps. V1-D scope patched. **Remaining three (P3):** `project` stays as doc-note equivalence (no rename); total estimate 17.5–19.5 focused days; release notes must NOT canonize "Minions" — neutral "queued background processing / async workers" only. **Sign-off:** "with those edits, I'd sign off on the five questions. The only non-architectural uncertainty left in the plan is scheduling discipline against the current Now list; that does not block V1-0 once the soak window and memory-density gate clear." **Status:** Claude + Codex agreed. Plan frozen pending Antoine final accept and gate clearance. Claude to commit Codex's patches + push.

 - **2026-04-22 Claude (late night)** Codex second-round review did the full file-level audit and came back with three P1/P2 findings, all with exact file:line refs. Verified each against current code before revising. (1) **F-1 not clean**: `Entity` dataclass at `service.py:67` and `entities` table schema are missing the `extractor_version` and `canonical_home` shared-header fields required by `engineering-v1-acceptance.md:45`; `project` field is the project identifier but not named `project_id` as spec writes (spec wording "fields equivalent to" allows the naming, but needs explicit doc note). V1-0 scope now includes adding both missing fields via additive `_apply_migrations` pattern. (2) **F-2 needed exact statuses, not guesses**: per-function audit gave ground truth — 9 of 20 v1-required queries done, 1 partial (Q-001 returns project-wide tree not subsystem-scoped expand=contains per `engineering-query-catalog.md:71`), 10 missing. V1-A scope shrank to Q-001 shape fix + Q-6 integration (most pillar queries already implemented); V1-C closes the 8 net-new queries + Q-020 to V1-D. (3) **F-5 misframed**: the generic `conflicts` + `conflict_members` schema is ALREADY spec-compliant at `database.py:190`; divergence is detector body at `conflicts.py:36` (per-type dispatch needs generalization) + route path (`/admin/conflicts/*` needs `/conflicts/*` alias). V1-F no longer includes a schema migration; detector generalization + route alignment only. Totals revised to 16.5–17.5 days, ~60 tests (down from 12–17 / 65 because V1-A and V1-F scopes both shrank after audit). Three of the eight open questions resolved. Remaining open: F-7 graduation depth, mirror determinism, `project` naming, velocity calibration, minions-as-V2 naming. No code changes this session — plan + ledger only. Next: commit + push revised plan, then await Antoine+Codex joint sign-off before V1-0 starts.
 
 - **2026-04-22 Claude (night)** Codex first-round review of the V1 Completion Plan summary came back with four findings. Three substantive, one workspace-sync: (1) "50–70% built" too loose — replaced with per-criterion table, global framing withdrawn; (2) phase order backward — provenance-at-write (F-8) and conflict hooks (F-5 minimal) depend-upon by every later phase but were in V1-E; new V1-0 prerequisite phase inserted to establish write-time invariants, and V1-A shrunk to a minimum query slice (four pillars Q-001/Q-005/Q-006/Q-017 + Q-6 integration) rather than full catalog closure; (3) "parallel with Now list / disjoint surfaces" too strong — real collisions listed explicitly (V1-0 provenance + memory extractor write path, V1-E graduation + memory module, V1-F conflicts migration + memory promote); schedule shifted ~4 weeks, V1-0 cannot start during pipeline soak; (4) Codex's Playground workspace can't see the plan file or the `src/atocore/engineering/` code — added a Workspace note to the plan directing per-file audit at the Windows canonical dev tree (`C:\Users\antoi\ATOCore`) and noting the three visible file paths (`docs/plans/engineering-v1-completion-plan.md`, `docs/decisions/2026-04-22-gbrain-plan-rejection.md`, `DEV-LEDGER.md`). Revised plan estimate: 12–17 days across 7 phases (up from 11–14 / 6), ~65 tests added (up from ~50). V1-0 is a hard prerequisite; no later phase starts until it lands. Pending Antoine decision on workspace sync (commit+push vs paste-to-Codex) so Codex can do the file-level audit. No code changes this session.
