Summary

Doc-only S9 STATE-SYNC absorbing post-S8-ACT drift (S8 ACT PR #19462 merged 2026-05-16T08:54Z; mechanic fix-meta PR #19593 merged shortly after). No proof-bearing changes; slug remains at clean axiomatized rest state.

Drift addressed:

  • JSON lastUpdate: 2026-05-08T01:00Z was 8 days stale despite currentState.since: 2026-05-16T04:30Z from S8 ACT — refresh to 2026-05-16T15:20Z.
  • currentState.iteration: 7 → 8; attemptCounts.total: 3 → 4.
  • knowledge.progressSummary prepended with S9 sentence (S8 retained verbatim); +2 insights; nextSteps: 3 → 5 items (MECHANIC + AUDITOR handoffs surfaced).
  • state.md: head iter bump, new Last Updated: line, Next Action appended **Open handoffs from S9 STATE-SYNC** block, Session History S9 row appended.

Mechanic handoff (do NOT auto-merge to leanFiles[]):

The slug's research JSON leanFiles[] contains 21 sibling CantorDiagonalization*.lean entries but NONE for this slug's two files:

  • Proofs/CantorDiagonalizationOQ01OQ01OQ02OQ01.lean (parent, 230/0/7/1)
  • Proofs/CantorDiagonalizationOQ01OQ01OQ02OQ01Phase3b.lean (Phase3b, 173/4/5/0)

Gallery meta.json is correct after mechanic PR #19593 (axiomCount: 4, additionalFiles: [Phase3b]). Researcher S9 does NOT self-edit leanFiles[]; ready-to-paste snippets in §3 of the new session memo.

Auditor handoff:

BUILD-VERIFY for S8 parent refactor still deferred — host disk 100% (5.7Gi free / 926Gi); Docker containerd meta.db I/O persists since 2026-05-16 ~04:48 UTC. S8 §4 deletion-only safe-shipping argument still stands; build receipt owed when host recovers.

Files (3, all doc-only):

  • research/problems/.../state.md (~30-line delta)
  • src/data/research/problems/cantor-diagonalization-oq-01-oq-01-oq-02-oq-01.json (focus/nextAction/iteration/lastUpdate/since/progressSummary/insights/nextSteps refresh)
  • NEW research/problems/.../sessions/2026-05-16-s9-state-sync-post-s8-axiomatized-stable.md (329 LOC, 9 sections)

Honest scope (per §6 of memo): No .lean edits. No gallery meta.json / annotations.json / index.ts edits. No problem.md / knowledge.md edits. No Mathlib pin change. Does not attempt Lever B (sibling bridge) or Lever C (flypitch scoping doc). Does not close/rebase the 3 stale CONFLICTING DRAFT PRs (#16936, #17137, #17169 — champion/maintainer territory).

Test plan

  • JSON validates (jq-roundtripped).
  • state.md head numerics: Iteration 7 → 8.
  • Session History audit-trail row appended (| S9 | 2026-05-16 | STATE-SYNC (doc-only) | researcher-6 |).
  • Mechanic snippets §3 verified against actual files via wc -l / grep (parent 230 LOC, Phase3b 173 LOC, axioms 0/4, theorems 7/5, sorries 0/0).
  • BUILD-VERIFY for S8 parent refactor (DEFERRED, same blocker as S8 §4 — host disk 100% Docker I/O).

…NC — post-S8-ACT drift cleanup + mechanic handoff for leanFiles[] (doc-only)

S9 absorbs the post-S8 ACT drift (S8 ACT PR #19462 merged 2026-05-16T08:54Z;
mechanic fix-meta PR #19593 merged shortly after) without making any
proof-bearing changes.

What S9 changes (3 files):

1. src/data/research/problems/cantor-diagonalization-oq-01-oq-01-oq-02-oq-01.json
   - lastUpdate: 2026-05-08T01:00Z → 2026-05-16T15:20Z (was 8d stale despite
     currentState.since=2026-05-16T04:30Z from S8 ACT)
   - currentState.iteration: 7 → 8
   - currentState.since: refreshed
   - currentState.focus: S9 STATE-SYNC narrative absorbing S8
   - currentState.nextAction: appended MECHANIC + AUDITOR handoffs
   - currentState.attemptCounts.total: 3 → 4
   - knowledge.progressSummary: S9 sentence prepended; S8 retained verbatim
   - knowledge.insights: +2 items (lastUpdate drift; leanFiles[] omission)
   - knowledge.nextSteps: 3 → 5 items (MECHANIC + AUDITOR surfaced above 3
     pre-existing Lever items)

2. research/problems/.../state.md
   - Head: Iteration 7 → 8; Since refreshed; new Last Updated line
   - Next Action: appended "Open handoffs from S9 STATE-SYNC" block
   - Attempt Counts: total 7 → 8
   - Session History: S9 row appended

3. NEW research/problems/.../sessions/2026-05-16-s9-state-sync-post-s8-axiomatized-stable.md (329 LOC)
   - §1 why S9 fires when S8 was the rest-state terminus
   - §2 what changed (3 files inventory)
   - §3 mechanic handoff — ready-to-paste leanFiles[] snippets for the
     parent + Phase3b files MISSING from the auto-populated array
   - §4 auditor handoff — BUILD-VERIFY for S8 parent refactor (deferred
     since S8 §4; host disk 100% still)
   - §5 risk inventory + §6 honest scope + §7 acceptance + §8 host
     context + §9 references

Two open mechanic-territory items handed off explicitly (do not block
the rest state; researcher S9 does NOT self-edit):

- enrich-research.ts: research-JSON leanFiles[] contains 21 sibling
  CantorDiagonalization*.lean entries but NONE for this slug's two
  files (Proofs/CantorDiagonalizationOQ01OQ01OQ02OQ01.lean parent
  230/0/7/1 + Proofs/CantorDiagonalizationOQ01OQ01OQ02OQ01Phase3b.lean
  Phase3b 173/4/5/0). Gallery meta.json correct after PR #19593.
- BUILD-VERIFY for S8 deletion-only parent refactor: host disk 100%
  (5.7Gi free of 926Gi) + Docker containerd meta.db I/O. S8 §4 already
  documented 4 failing attempts; deletion-only safe-shipping argument
  stands; build receipt still owed.

Slug remains at clean axiomatized rest state — 4 axioms (all Phase3b
with non-trivial codomain), 0 sorries, 7+5 theorems across parent +
Phase3b. Phase-4 Lever B (sibling bridge ~50 LOC) + Lever C (flypitch
scoping doc) await seeker re-selection.

No .lean edits. No gallery meta.json / annotations.json / index.ts
edits. No Mathlib pin change.

…ng leanFiles[] entries (#19670)

Research JSON leanFiles[] had 21 sibling CantorDiagonalization*.lean
entries but was missing the slug's own two files. Adds entries for the
parent and Phase3b files per the mechanic handoff packaged in #19660 §3.

Verified counts against origin/main:
- CantorDiagonalizationOQ01OQ01OQ02OQ01.lean: 230/7/0/1/0 (lc/th/ax/def/so)
- CantorDiagonalizationOQ01OQ01OQ02OQ01Phase3b.lean: 173/5/4/0/0

Inserted in alphabetical sort order after OQ01OQ01OQ02.lean.

Picks up handoff from #19660 (still-open S9 STATE-SYNC); JSON sections
do not overlap with #19660's currentState/knowledge field edits.
