Claude: SESSION 30 CLOSED at rev 484 (Opus 4.8, 2026-07-02). Agent close-out after the v1.0.0 release (see the release entry below). Deleted working-session/HEARTBEAT.md + its heartbeat cron so no stale Claude steward continues; swept the nine session-30 Claude-owned/addressed mailbox cards (MSG-001/002/003/004/006/007/009/010/012) into the Closed Summary; set Claude idle / current_task null / last_seen claude-session-30-close and posted SIG-424 yield; rolled boot-claude v23 → v24 (de-hardcoded the drifted agent/PRD/skill/eval counts into live lookups, added the v1.0.0 milestone line; v23 archived to docs/archive/boot-claude/). Gates at close: validate-closeout --agent claude clean:true, mailbox-invariants PASS (0 open / 0 active / 84 closed), turnfile-lint + schema PASS at rev 484. Carry-forward: no open Claude-lane blockers; v1.0.0 shipped (commit 3bc1905 + tag v1.0.0 on origin, GitHub release live). Next session queries live state via session-orient / prd-status-summary; AIDR is being polished in a parallel session.

Claude: TURNFILE v1.0.0 RELEASED (Opus 4.8, 2026-07-02). Maintainer ratified the PRD-047 cross-repo dogfood evidence outcome (Tokenese + AIDR), recorded in the promoted PRD-047 doc's Maintainer Ratification section. Claude closed MSG-20260623-028 under Maintainer authorization (Codex closure-owner offline), promoted PRD-047 to docs/prds/ (registry 48 tracked / 46 promoted), bumped turnfile.version to 1.0.0, and aligned the version scheme to full Semantic Versioning at Maintainer direction (turnfile-v0 schema pattern X.Y → MAJOR.MINOR.PATCH; all TURNFILE.yaml files, templates, examples, and eval fixtures converted). Public surface refreshed to v1.0.0 via the canonical-spec-page skill (docs/index.html, llms.txt, assistant-guide + .well-known, manifest hashes). Session-30 Claude deliveries: PRD-047 Test 2 retarget PAICE2 → AIDR (Maintainer-directed), with the AIDR-0002 SPEC v0.1.0 ratification as the dogfood's real-work item; AIDR dogfood run + evidence, which found and drove fixes for two portable-CLI cold-start bugs via independent fresh-temp verification; AIDR repo reconciled + committed (fd9a666); PRD-049 A1 step-7 review to convergence (C1 one-voice validator + C2 boot-refusal counters, both resolved). Gates green: validate-v1-release ok:true; turnfile-lint / prd-promotion / public-surface / mailbox-invariants all PASS. Release tagged v1.0.0.

Codex: SESSION 30 CLOSED at rev 483. Maintainer asked Codex to leave a message for Claude and close the session. Codex routed MSG-20260702-012 to Claude summarizing the session-30 changes and rationale, deleted the app heartbeat turnfile-codex-readonly-steward-s30 so no stale Codex steward continues, and set Codex status idle with current_task null and session_id null. Carry-forward: MSG-20260623-028 remains active/actioned under Codex closure ownership, explicitly deferred because closure requires Maintainer dogfood evidence ratification. Codex unread 0; locks none.

Codex: SESSION 30 WORKING-SESSION CONTENT CLEANUP at rev 482. Maintainer asked Codex to apply the same cleanup level to working-session/ content and surface issues/recommendations. Codex added working-session/README.md as a live directory map, expanded working-session/docs/README.md to classify active release evidence, onboarding evidence, historical implementation notes, Tokenese artifacts, and organization recommendations, corrected the stale PRD-047 gate snapshot so Claude acceptance/evidence review is current and only Maintainer dogfood evidence ratification remains, and added current-use notes to NEXT_SESSION_HANDSHAKE.md and SESSION_CHARTER.md to prevent historical addenda/charters from being mistaken for live session state. Peer-owned boot/chat files and Claude's heartbeat sentinel were not edited.

Codex: SESSION 30 PRD-049 ACCEPTED + PROMOTED at rev 481. Maintainer reported answering PRD-049 questions and providing acceptance. Live files already recorded Claude's C1/C2 re-review as APPROVE with no remaining counters, and PRD_STATUS already had Codex/Claude/Gemini/Maintainer accepted evidence. Codex cleared the stale PRD-049 blocking_items, flipped implementation.state to done, moved PRD-049-same-family-multi-instance-collaboration.md from working-session/docs/ to docs/prds/, updated the PRD header/snapshot to Accepted, closed MSG-20260702-008, refreshed README/docs/llms counters to 48 tracked / 45 promoted, and added PRD-049 to docs/prds/PRD_SHELF_RECONCILIATION.json as the optional same-family multi-instance profile.

Codex: SESSION 30 PRD-048 HELPER PATH COLD-START FIX at rev 480. Maintainer relayed Claude's fresh-temp smoke showing a second-layer PRD-048 failure: after init created NEXT_SESSION_HANDSHAKE.md, open --root still failed because handshake-sign.mjs tried to run tools/export-mailbox-json.mjs from the adopter target root. Codex fixed helper resolution so handshake-sign.mjs resolves helper scripts and the Turnfile schema from the Turnfile repo while keeping target files under the --root cwd. Codex also made turnfile close --root use the target root with a repo-root schema and a deterministic empty PRD registry fallback when fresh adopters have no PRD_STATUS.json. PRD-048's true cold-start eval now asserts the target has no copied tools/ directory and requires init -> open --root -> status --root -> close --root --dry-run to exit 0. Verification: node --test evals/prd-048.evals.mjs PASS 16/16; node --test evals/prd-040.evals.mjs evals/prd-043.evals.mjs evals/prd-047.evals.mjs evals/prd-048.evals.mjs PASS 42/42; independent fresh-temp no-target-tools smoke PASS with close_status: 0. MSG-20260702-010 remains active/actioned under Claude closure ownership for re-review/closure.

Gemini: SESSION 30 CLOSED at rev 479. Gemini closed session 30. Deleted Gemini heartbeat; status is idle, current_task is null, last_seen is gemini-session-30-close. Completed task s30-handshake-heartbeat. Mailbox has 0 unread messages for Gemini. Workspace validation gates pass.

Codex: SESSION 30 PRD-040 HEARTBEAT PRD_STATUS SWEEP IMPLEMENTED at rev 478. Heartbeat found Gemini had actioned MSG-20260702-011 by adding RED eval AC2/R2.5 to evals/prd-040.evals.mjs, requiring tools/validate-heartbeat-loop.mjs to notify on pending selected-agent PRD_STATUS ownership. Codex implemented a read-only PRD_STATUS sweep for pending selected-agent acceptance and incomplete selected-agent implementer/reviewer/eval_author rows, excluding rows with blocking_items so blocked PRD-047/PRD-049 do not appear executable. Verification: node --test evals/prd-040.evals.mjs PASS 7/7; live Codex heartbeat-loop still reports active sent-message cards and no PRD_STATUS work; Gemini heartbeat-loop DONT_NOTIFY. Codex closed MSG-20260702-011 as closure owner.

Gemini: SESSION 30 PRD-040 RED EVAL ADDITION at rev 477. Gemini actioned unread MSG-20260702-011 by authoring a RED contract eval in evals/prd-040.evals.mjs (AC2/R2.5) to assert that tools/validate-heartbeat-loop.mjs considers pending PRD_STATUS.json work in its heartbeat sweep, preventing future misses. Added JSON prdStatus writing support to the test's createFixtureWorkspace helper. The test suite passes 6/7 tests, with the new test failing on DONT_NOTIFY as expected. Handoff to Codex to implement.

Codex: SESSION 30 EVAL HARDENING + PRD-048 COLD-START FIX at rev 476. Maintainer asked Codex to create evals for Codex-authored PRDs and suggest other PRD authors author recommended evals. Codex added Codex-owned eval coverage: PRD-047 now asserts reviewed Tokenese+AIDR evidence remains blocked only on Maintainer dogfood evidence ratification with MSG-20260623-028 actioned/open; PRD-043 now asserts validate-v1-release explains active MSG-20260623-028 as a Maintainer ratification blocker when the mailbox end gate fails. During verification, Claude routed MSG-20260702-010 showing the PRD-048 cold-start init -> open --root gap. Codex actioned it: turnfile init now creates working-session/NEXT_SESSION_HANDSHAKE.md, templates/v1-minimal includes the starter handshake file, and PRD-048 now tests a true fresh init -> open --root -> status -> close --dry-run path. Verification: node --test evals/prd-047.evals.mjs PASS 6/6; node --test evals/prd-043.evals.mjs PASS 13/13; node --test evals/prd-048.evals.mjs PASS 16/16. Routed MSG-20260702-011 to Gemini recommending Gemini-authored PRD-040 heartbeat final-sweep coverage for PRD_STATUS-owned work.

Codex: SESSION 30 PRD-047 AIDR EVIDENCE REVIEW + PRD-048 FIXES at rev 474. Heartbeat found the AIDR Test 2 evidence landed and reviewed MSG-20260623-028. Codex accepted the PRD-047 evidence shape after fixing the two dogfood findings in Codex-owned PRD-048 lane: tools/turnfile.mjs open --root now strips --root before delegating and runs handshake-sign.mjs in the target repo; handshake-sign.mjs now handles fresh-template compact tasks: {} / messages: [] and nullable agent last_seen; templates/v1-minimal/working-session/TURNFILE.yaml now has lint-clean starter defaults. Added a real open --root PRD-048 regression. Verification: node --test evals/prd-048.evals.mjs PASS 15/15, node --test evals/prd-047.evals.mjs PASS 5/5, starter template lint PASS, PRD promotion validator PASS, v1 gate summary READY. MSG-20260623-028 remains active/actioned because its closure condition still requires Maintainer dogfood evidence ratification.

Codex: SESSION 30 PRD-049 COUNTERS APPLIED at rev 473. Heartbeat found Claude's A1 step-7 review on MSG-20260702-008: APPROVE with two counters before promotion. Codex applied both. C1: tools/validate-prd-promotion.mjs now enforces one-family-one-voice for acceptance/review records, accepting one family or instance-qualified record per required reviewer while failing multiple same-family accepted records such as claude/fable-5 plus claude/opus-4-8. C2: tools/handshake-sign.mjs now refuses a fourth same-family --instance before boot or dry-run, naming the cap and live instances. evals/prd-049.evals.mjs now covers both counters and passes 12/12. PRD-049 remains pending Claude closure/re-review and Maintainer ratification before promotion.

Codex: SESSION 30 AIDR-0002 DIRECT POSITION CONFIRMED at rev 472. Heartbeat found unread MSG-20260702-009 asking Codex to write its AIDR-0002 position directly or confirm the transcription. Codex confirmed the AIDR record now contains the direct Codex position with no transcription marker, then made minimal AIDR metadata corrections outside the Turnfile repo: status: approved to status: arbitrated, added decided: 2026-07-02, and normalized Arbitration metadata to SPEC/linter shape. Verification: node /Users/snap/Git/aidr/tools/aidr-lint.mjs /Users/snap/Git/aidr/decisions/AIDR-0002-ratify-spec-v0.1.0.md PASS with claims [independent-positions, human-arbitrated]. Codex actioned MSG-20260702-009; Claude remains closure owner.

Codex: SESSION 30 PRD-049 IMPLEMENTED + ROUTED FOR REVIEW at rev 470. Codex completed PRD-049 A1 step-5 implementation after diagnosing the heartbeat miss. Implemented additive same-family instance support in schemas/turnfile/turnfile-v0.schema.json; lint checks in tools/turnfile-lint.mjs for instance cap 3, exactly one primary, instance current_task validation, and family/instance task-owner compatibility; --instance direct-mode support in tools/handshake-sign.mjs; tools/turnfile.mjs open --instance dry-run payload and heartbeat write --instance sentinel path working-session/HEARTBEAT-<family>.<instance-id>.md; and docs/PROTOCOL_CORE.md invariants for one-family-one-voice, instance heartbeat sentinels, and ephemeral delegate/subagent attribution/no-quorum/no-direct-coordination writes. Verification: node --test evals/prd-049.evals.mjs PASS 10/10; live turnfile lint PASS; turnfile.mjs open --instance dry-run PASS; turnfile.mjs heartbeat write --instance PASS against /private/tmp. PRD_STATUS now marks Codex accepted and implementation eval-verified; routed MSG-20260702-008 to Claude for A1 step-7 review.

Gemini: SESSION 30 AIDR-0002 GOOGLE POSITION at rev 469. Gemini actioned unread MSG-20260702-007 by forming and writing an independent Google-provider recommendation position directly into Decisions record decisions/AIDR-0002-ratify-spec-v0.1.0.md under ~/Git/aidr. Verified record conformance using reference linter tools/aidr-lint.mjs (PASS, independent-positions earned).

Codex: SESSION 30 AIDR-0002 OPENAI POSITION + PRD-049 HEARTBEAT GAP FOUND at rev 468. Maintainer asked why Codex was not acting on PRD-049. Diagnosis: PRD-049 entered through PRD_STATUS.json as implementation.implementer: codex and acceptance.codex: pending, but no PRD-049 mailbox card or Codex task row existed; Codex heartbeat final sweep was mailbox/task-centric and missed registry-assigned implementation work. Codex updated app heartbeat turnfile-codex-readonly-steward-s30 to include PRD_STATUS rows where Codex is pending/implementer/reviewer/eval-author. Codex also actioned unread MSG-20260702-006 by forming an independent OpenAI-provider position on AIDR-0002 after reading only /Users/snap/Git/aidr/SPEC.md v0.1.0, before reading existing AIDR-0002 positions, and recorded the position in MAILBOX.md for Claude to compile into the AIDR record. PRD-049 remains RED and is now the next Codex implementation lane after the active unread AIDR request is cleared.

Codex: SESSION 30 MSG-001 LIFECYCLE REPAIR at rev 466. After Gemini's concurrent rev 465 Qwen preflight update, Codex re-read live files and found MSG-20260702-001 kept Codex's APPLY ack text but still showed Status: acknowledged. Codex repaired the status to actioned, regenerated MAILBOX.json, and left Gemini's rev 465 Qwen/PRD-049 updates intact.

Gemini: SESSION 30 QWEN PREFLIGHT EXECUTION at rev 465. Gemini successfully executed the Qwen onboarding preflight (OT-012/013/014) against the local Ollama qwen3.6:35b-mlx model. Qwen completed all three drills successfully with exact-output conformance. Recorded preflight, candidate output, and evaluator summary evidence files under working-session/docs/onboarding/evidence/qwen-mlx/2026-07-02-01/. Concurred on retargeting PRD-047 Test 2 to ~/Git/aidr in MSG-20260702-002, closed Codex advisory MSG-20260702-005, and updated PRD_STATUS.json to register the new PRD-049 draft.

Codex: SESSION 30 HEARTBEAT SELF-DRIVE CORRECTION + PRD-047 AIDR APPLY at rev 464. Maintainer clarified the heartbeat must end by asking whether any unblocked work in Codex's lane can be executed now, not only checking unread messages. Codex updated app automation turnfile-codex-readonly-steward-s30 to permit guarded ordinary Turnfile lifecycle execution for unblocked Codex-lane work after file refresh, next-state derivation, audit updates, MAILBOX.json regeneration, and validators. Codex then actioned MSG-20260702-001 APPLY: PRD-047 Test 2 target/gate changed from PAICE2 to AIDR in the active PRD, evals, v1 gate summary, PRD_STATUS, working-session docs index, and the live MSG-20260623-028 closure condition. Historical PAICE2 references in previous worklog/closed-summary records were left intact. PRD-047 remains RED until working-session/docs/v1-cross-repo-test-aidr-<date>.md lands; Claude remains operator/closure owner for the AIDR dogfood run.

Codex: SESSION 30 HEARTBEAT MITIGATION APPLIED at rev 463. Maintainer authorized agents to change their own setup without peer routing. Codex created app heartbeat turnfile-codex-readonly-steward-s30 at 5m cadence, destination current Codex thread, read-only. The heartbeat prompt refreshes files first, runs read-only orientation/heartbeat/mailbox/lint checks when available, notifies on material changes, and denies file edits, MAILBOX.json regen, status changes, signals, revision bumps, staging, and commits from the heartbeat itself. Codex left working-session/HEARTBEAT.md untouched because it currently names Claude, acknowledged Claude's PRD-047 AIDR retarget card MSG-20260702-001, and routed optional advisory pattern cards MSG-20260702-004/MSG-20260702-005 to Claude/Gemini for self-owned emulation if useful.

Codex: SESSION 30 BOOT + REPO LEVEL-SET CLEANUP complete at rev 461. Maintainer opened a new Turnfile session with Gemini 3.5 Flash and Opus 4.8 in scope and asked first to clean up/level set the repo, revealing open loops and tasks. Codex booted from files, confirmed Codex unread 0 and model-ledger coverage, opened and completed s30-codex-repo-level-set, preserved Gemini's concurrent session-30 boot at rev 457 and Claude's concurrent session-30 boot at rev 459, and reconciled stale task rows: s27-qwen-onboarding-exec done from PRD-042 evidence/rev402, prd-015-maintainer-acceptance done from PRD-015 reactivation/full-active evidence, s14-pre-prd027-checkpoint done from PRD-027 initiation approval, and session-29 done tasks now carry completed_rev values. Codex also repaired the session-30 handshake task ownership warning by creating s30-claude-handshake-heartbeat for Claude instead of leaving Claude pointed at Gemini-owned s30-handshake-heartbeat. Public/status cleanup: README PRD index now runs through PRD-048 with PRD-047 as the only draft; promoted PRD headers PRD-034/035/036/043/044/045/046/048 no longer claim draft/pending state. Current open loop: PRD-047 Test 2 PAICE2 dogfood evidence -> Codex evidence review -> Maintainer dogfood/final v1.0.0 ratification. MSG-20260623-028 remains active/actioned under Codex closure ownership until that evidence chain is satisfied or superseded.

Claude (Opus 4.7): SESSION 29 CLOSED at rev 454 (idle, current_task null, last_seen claude-session-29-close, SIG-395 yield). Largest substantive session to date: v0.5.0 released and applied; 5 PRDs (043/044/045/046/048) promoted to docs/prds; 8/9 v1.0.0 R9 gate conditions ready (only PRD-047 Test 2 PAICE2 evidence + Maintainer final ratify remain). Deliverables: PRD-043 v1 Minimal Governance Profile complete (MVT + schemas/v1 + validate-v1-profile + R10 fresh-context probe with two passing Haiku+Sonnet evidence files + PRD shelf reconciliation + R11 landing page); PRD-044 handshake-sign CLI direct flags; PRD-045 stale-agent reconciliation tool + new multi-agent-resilience profile; PRD-046 repo minimization archive via git-revision-pointer model; PRD-048 portable Turnfile CLI five-verb dispatcher (init/open/status/heartbeat/close); PRD-047 cross-repo dogfood tests scope authored; Tokenese Phase B opened inside ~/Git/tokenese (Test 1 evidence + t2 multi-family A/B suite design strawman with 4 OQs routed for Maintainer pick). Major amendments per Maintainer 10-item directive: PRD-018 R2.3 (OQ-069 self-owned-file selective unlock with inform-and-confirm); PRD-027 R6.5 (A/B pilot exit = three-peer agreement); PRD-017 R2.1 (orient-clean fast-path); PRD-038 R9/R10/R11 (self-drive + HEARTBEAT.md sentinel + adopter-profile conformance); INTENT v0.1.2 + ROADMAP v0.1.4 with six clarifications each; INTENT invariant #3 expanded for sub-rung Maintainer-routing per PRD-039/042 ladder; PRD-001/004 reply-template overlap resolved (PRD-004 canonical for decisions). Boot-claude.md + boot-codex.md rewritten per boot-file-must-be-lookup-not-state pattern; new tools/prd-status-summary.mjs built to support the lookup. Eight new tools shipped this session (validate-v1-profile, validate-v1-release, validate-mailbox-session-gate, reconcile-stale-agent, turnfile.mjs, prd-status-summary, compare-turnfile-tasks, validate-task-aggregate). Seven memory entries saved on session-29 Sam corrections covering proactive-advance, heartbeat-self-drive, prd-acceptance-canonical, boot-file-lookup, always-link-when-asking, when-maintainer-approves-apply-immediately. Heartbeat steward turnfile-session-29-heartbeat deleted at close. Carry-forward: PRD-047 Test 2 PAICE2 participant pick + run; Tokenese OQ-PhaseB-1/2/3/4 strawman decisions; final v1.0.0 ratify after Test 2. Mailbox clean (1 active card MSG-028 Codex-owned, awaiting PRD-047 evidence). Boot v22 archived to docs/archive/boot-claude/boot-claude_v22.md; v23 written with same lookup pattern. Carry-forward also includes Gemini orphan-close self-reconciliation on next Gemini boot (Gemini-owned paths unchanged this session per OQ-069 boundary).

Codex: SESSION 29 CLOSED at rev 455. Maintainer asked Codex to prep the next session and close session 29. Codex deleted app heartbeat turnfile-codex-readonly-steward-s29; Codex status is idle with current_task null and last_seen codex-session-29-close; inbox unread 0; locks none. Session 29 Codex deliveries: PRD-043 author/eval lane; PRD-044 and PRD-045 author plus A1 review lanes; PRD-046 author and implementation review support; PRD-048 portable CLI implementation; mailbox session gate and v1 release wrapper; PRD-047 evidence contract; intent/roadmap/public-surface/repo-structure cleanup; v0.5.0 promotion support; boot-codex lookup-pattern rewrite. Carry-forward: MSG-20260623-028 remains open/actioned under Codex closure ownership for PRD-047; v1.0.0 remains gated on PAICE2 dogfood evidence, Codex evidence review, and Maintainer evidence ratification. Closeout validator is clean with active_card_owner_review explicitly deferred for MSG-20260623-028.

Codex: SESSION 29 STRUCTURAL ORGANIZATION CLEANUP at rev 453. Maintainer asked Codex to take action on seven repo-structure items. Codex confirmed completed PRDs should not remain as working-session drafts, kept only PRD-047 in working-session/docs, reconciled PRD_STATUS so Gemini is not an active required reviewer for the Codex/Claude session-29 lane, removed all .DS_Store files and added **/.DS_Store to .gitignore, added docs/REPO_MAP.md, docs/PUBLIC_SURFACE.md, examples/README.md, and tools/README.md, added future tool layout consolidation to ROADMAP.md, synced public surfaces to 47 registry-tracked / 44 promoted, restored the active MSG-20260623-028 mailbox stub, regenerated MAILBOX.json, and updated PRD-043/044/045/046/048 eval registry assertions for promoted accepted PRDs. Verification: focused PRD suite 44/44 PASS, mailbox invariants PASS, PRD promotion PASS, public-surface snapshot PASS, no .DS_Store files remain.

Codex: SESSION 29 BOOT-CODEX LOOKUP PATTERN APPLIED at rev 449. Heartbeat found unread Codex advisory MSG-20260623-031 from Claude recommending the boot-file-must-be-lookup pattern for working-session/boot-codex.md. Codex applied the recommendation to its own boot file: bumped to v19, removed session 26-28 close snapshots, PRD-specific carry-forward, and stale next-session plans, and replaced them with live lookup commands (session-orient, prd-status-summary, validate-v1-release) plus pointers to WORKLOG tail, MAILBOX active cards, and TURNFILE live state. MSG-20260623-031 is actioned with Codex unread 0. boot-gemini.md was not edited because it is Gemini-owned.

Codex: SESSION 29 MAINTAINER ACCEPTANCE CARRY-FORWARD at rev 448. Maintainer clarified that accepted PRDs, specifically PRD-043, should not be re-asked for approval unless the PRD itself changes substantially. Codex recorded this as repo-level intent in INTENT.md v0.1.3, removed stale maintainer-approval blockers from accepted PRDs PRD-043/044/045/046/048 in PRD_STATUS.json, left PRD-047 PAICE2 dogfood evidence blockers intact, and renamed the v1 gate check in tools/prd-status-summary.mjs so PRD-043 maintainer acceptance carries forward instead of appearing as a new ratification request.

Codex: SESSION 29 ROADMAP PRD SHELF CLEANUP COMPLETE at rev 445. Maintainer asked whether roadmap item 6, PRD shelf cleanup, can be resolved in this session. Codex verified PRD_STATUS.json covers 47 registered PRDs and refreshed docs/prds/PRD_SHELF_RECONCILIATION.json through PRD-048. The reconciliation now contains 48 entries including PRD-025 supersession, classifies PRD-046 as historical/provenance support, PRD-047 as draft release-evidence, and PRD-048 as core-v1 operational entry point. ROADMAP.md item 6 now marks PRD shelf cleanup complete for v1 release-candidate planning and requires future PRDs after PRD-048 to update both lifecycle status and shelf reconciliation before release claims rely on them.

Codex: SESSION 29 ROADMAP FRONT MATTER at rev 444. Maintainer asked Codex to add YAML headers to ROADMAP.md similar to INTENT.md and asked whether a roadmap changelog is needed. Codex added title, version, last_updated, status, description, and tags front matter. Codex did not add a changelog because ROADMAP.md is non-normative planning; git history plus WORKLOG is sufficient unless roadmap decisions become independently ratified artifacts.

Codex: SESSION 29 ROADMAP V1 ALIGNMENT at rev 442. Heartbeat found no Codex unread mailbox work and one safe unblocked Codex-lane item from the Maintainer roadmap discussion. Codex updated ROADMAP.md to mark scope reconciliation complete for v1 release-candidate planning, make Section 4 feature-specific as Fast audit-preserved coordination, remove the PRD-number-driven Tokenese work list from the roadmap body, refresh starter/CLI/shelf cleanup statuses, and replace narrowed-v0.2 readiness with v1.0.0 evidence and arbitration gates.

Codex: SESSION 29 PRD-047 TOKENESE PARTIAL REVIEW + PRD-048 STATUS FIX at rev 440. Heartbeat found Tokenese Test 1 evidence at working-session/docs/v1-cross-repo-test-tokenese-2026-06-23.md. Codex reviewed it against PRD-047: Tokenese evidence shape passes the Tokenese-specific eval, target mailbox invariants pass, and tools/turnfile.mjs status --root /Users/snap/Git/tokenese --emit json now reports target revision 2. During review, Codex found and fixed a PRD-048 dispatcher bug where status --root ignored the target root and reported the Turnfile repo; added a regression test and verified node --test evals/prd-048.evals.mjs 14/14 PASS. PRD-047 remains RED because PAICE2 evidence is missing. Additional issue surfaced: validate-v1-profile --root /Users/snap/Git/tokenese fails the broad historical-PRD scan on Tokenese-owned PRD references, so consumer-repo validator scope needs clarification before claiming target v1-profile PASS.

Codex: SESSION 29 MSG-029 CLOSED at rev 438. Claude APPLY'd the Codex PRD audit and intent-document recommendations, and Codex applied the INTENT.md v1 release-candidate strategy updates. Codex closed MSG-20260623-029 as closure owner. MSG-20260623-028 remains open because its closure condition explicitly waits for PRD-047 Tokenese evidence.

Codex: SESSION 29 INTENT STRATEGY EDIT APPLIED at rev 437. Maintainer revised INTENT.md and asked Codex to make the additional recommended edits. Codex added current v1 release intent, fresh-adopter adoption test language, profile boundary, stable release gate, revised admission criteria for pre-freeze and post-freeze changes, stale participant strategy, updated development posture, and a 2026-06-23 changelog entry.

Codex: SESSION 29 PRD AUDIT + INTENT RECOMMENDATIONS ROUTED at rev 436. Maintainer asked Codex to make recommendations to Claude for the PRD audit and suggest revisions to each intent document. Codex reviewed current intent surfaces (INTENT.md, ROADMAP.md, VISION.md, SPEC.md, CONFORMANCE.md, README.md, and PRD_SHELF_RECONCILIATION.json) and routed MSG-20260623-029 to Claude. Recommendations: update the PRD audit to reflect PRD-046 done and PRD-047 draft/evidence-pending; separate v1 blockers from optional-profile unfinished work; refresh shelf reconciliation after PRD-047; revise INTENT.md for v1 release intent and expanded R9; revise ROADMAP.md to current v1 gate status; resolve VISION.md authority conflict with INTENT.md; add release wrapper and PRD-047 evidence references to CONFORMANCE.md/SPEC.md; keep public surfaces focused on four-doc v1 path plus CLI.

Codex: SESSION 29 PRD-047 CROSS-REPO EVIDENCE CONTRACT AUTHORED at rev 435. With PRD-046 implementation done, Codex advanced the next unblocked expanded-R9 gate lane by drafting working-session/docs/PRD-047-cross-repo-v1-validation-tests.md and RED evals evals/prd-047.evals.mjs. The split preserves A1 separation: Codex authored the evidence contract/evals; Claude performs the Tokenese and PAICE2 operational dogfood runs unless Maintainer redirects; Codex reviews evidence; Maintainer ratifies pass/fail before final v1.0.0. Routed MSG-20260623-028 to Claude for apply-or-counter and operational sequencing. Expected current eval state: RED until both v1-cross-repo-test-tokenese-<date>.md and v1-cross-repo-test-paice2-<date>.md evidence files exist.

Codex: SESSION 29 PRD-046 STEP-7 APPROVE at rev 434. Heartbeat found Claude MSG-20260623-027 requesting A1 step-7 review for the PRD-046 minimization implementation. Codex independently inspected examples/turnfile-development/README.md and public-surface updates, accepted the git-revision-pointer archive model, README v1 quick-start/archive-boundary restructure, assistant-guide v1 placement, and deferral of detailed docs/llm/MODEL_LEDGER.md row migration to the final release-prep snapshot unless Maintainer requests earlier. Verification: node --test evals/prd-046.evals.mjs evals/prd-034.evals.mjs evals/prd-043.evals.mjs evals/prd-048.evals.mjs 38/38 PASS; node tools/validate-public-surface-snapshot.mjs PASS. PRD-046 implementation.state flipped to done; promotion remains Maintainer-gated.

Claude (Opus 4.7): SESSION 29 PRD-046 IMPLEMENTED + R10 EVIDENCE LANDED + PRD-048 STEP-7 APPROVE at rev 433 (SIG-377). Three lanes advanced in parallel via fan-out per Sam standing directive (proactive-advance-lanes memory): (1) Two fresh-context probes spawned via Agent tool with model: haiku + model: sonnet — both 5/5 PASS on the FRESH_CONTEXT_CONFORMANCE_PROBE.md five questions (TURNFILE/MAILBOX/WORKLOG triad, sender-or-maintainer closure rule, 5-tier authority order + agent consensus cannot override, lease formula→rev 10, Tokenese+heartbeat optional profiles + PRD_SHELF_RECONCILIATION classification location); evidence at working-session/docs/v1-fresh-context-probe-2026-06-23-claude-{haiku,sonnet}.md. PRD-043 R10 eval check satisfied → 12/12 PASS. (2) PRD-048 step-7 APPROVE (inspected tools/turnfile.mjs 332 lines: per-command function decomposition, EXIT code map, copyFileWithSubstitutions + runNode + mirrorAndExit helpers; evals 13/13). PRD-048 implementation.state→done. (3) PRD-046 implementation: examples/turnfile-development/README.md (~80 lines, git-revision-pointer model per C2 — anchor commits fd26f8a session-12 + 767e07b session-28-close + session-29-close future-anchor; indexes WORKLOG/MAILBOX/retired-drafts/model-ledger/PRD-shelf/boot-file history without content duplication); README.md gains v1 Quick start (4 docs + CLI) + Archive boundary section with legacy quick start preserved per OQ-046-1; docs/llms.txt + assistant-guide.txt + manifests (sha256 refreshed root + served) gain v1 Minimal Governance Profile + Archive boundary sections. evals/prd-046.evals.mjs 4/4 PASS. PRD_STATUS: PRD-048 done, PRD-046 eval-verified pending Codex step-7. Routed MSG-20260623-027 to Codex. Bundle (PRD-034/043/046/048) 38/38, run-evals 27/27, validate-public-surface-snapshot PASS. validate-v1-release.mjs reports ok:false only because MSG-027 actioned at scan; next run after Codex closure should report ok:true on 6/7 gates. Remaining expanded-R9-gate conditions: PRD-047 cross-repo dogfood tests (Codex authors per MSG-023 reply) + Maintainer ratify.

Codex: SESSION 29 PRD-048 APPROVED + PRD-046 COUNTERS APPLIED at rev 432. Heartbeat refreshed state and found Claude actioned MSG-20260623-026: PRD-048 A1 step-7 APPROVE and PRD-046 APPLY with counters C1-C3. Codex accepted the verdict, applied C1-C3 to working-session/docs/PRD-046-repo-minimization-archive.md and evals/prd-046.evals.mjs, updated PRD_STATUS notes, closed MSG-20260623-026, and recorded SIG-376. PRD-048 is implementation done; PRD-046 remains RED/pending Claude implementation until examples/turnfile-development/README.md and stable-surface/archive docs land.

Codex: SESSION 29 PRD-048 IMPLEMENTED + PRD-046 NARROWED at rev 431. Heartbeat refreshed state and found Claude MSG-20260623-025 routing PRD-048 Portable Turnfile CLI to Codex under Maintainer direction. Codex APPLY'd PRD-048 scope and OQ-048-1/2/3, implemented tools/turnfile.mjs with init, open, status, heartbeat, close, --help, and --version, and verified node --test evals/prd-048.evals.mjs 13/13 PASS. Codex also narrowed PRD-046 to minimization/archive only because PRD-048 owns portable CLI, adding working-session/docs/PRD-046-repo-minimization-archive.md and evals/prd-046.evals.mjs; PRD-046 evals remain RED until examples/turnfile-development/README.md and archive/stable-surface docs land. PRD_STATUS updated for PRD-046 and PRD-048. MSG-20260623-024 closed after Claude APPLY'd the R10 release-wrapper review; MSG-20260623-026 routed to Claude for PRD-048 A1 step-7 review and PRD-046 apply-or-counter review.

Claude (Opus 4.7): SESSION 29 PRD-048 PORTABLE CLI AUTHORED at rev 430 (SIG-374). Maintainer-directed inverted-split: Claude eval-author + Codex implementer + Claude reviewer (PRD-006 A1 exception per Sam directive "define these scripts now in terms of PRD and evals, and hand them off to Codex to deliver"). Wrote PRD-048 body (R1-R10 + 10 AC + 3 OQ) covering five-verb tools/turnfile.mjs dispatcher: init (NEW scaffold from templates/v1-minimal/), open (wrap handshake-sign.mjs PRD-044 direct flag mode), status (wrap session-orient.mjs), heartbeat write|stop (NEW HEARTBEAT.md sentinel with PRD-038 read-only contract + self-drive rule from feedback-heartbeat-must-self-drive memory), close (NEW 9-step orchestrator: export-mailbox-json → validate-mailbox-invariants → validate-closeout → turnfile-lint → validate-prd-promotion → heartbeat stop → TURNFILE idle/rev bump/yield SIG → WORKLOG close-line → MAILBOX.json regen). Wrote evals/prd-048.evals.mjs 13 RED tests (10 fail / 3 pass = properly RED). PRD-046 narrowed to minimization-archive-only (CLI scope reassigned to PRD-048); also registered in PRD_STATUS (was on-disk but missing per Codex's rename to PRD-046-repo-minimization-archive.md). Dedupe applied. Codex's MSG-024 PRD-043 R10 release-gate hardening APPLY'd no counter — R10 now correctly fails until working-session/docs/v1-fresh-context-probe-* evidence exists; validate-v1-release.mjs aggregates 7 checks. Routed MSG-20260623-025 to Codex as PRD-048 implementation handoff. Sequencing proposed: PRD-048 before PRD-046 (minimization preserves only scripts that exist, and CLI is what scripts are). Gates: turnfile-lint PASS, prd-promotion PASS (46 PRDs).

Codex: SESSION 29 PRD-043 R10 RELEASE GATE HARDENED at rev 429. Heartbeat found no unread Codex mailbox work, but MSG-20260623-023 left an unblocked Codex lane: PRD-043 R10 evidence hardening plus a validate-v1-release.mjs wrapper. Codex updated evals/prd-043.evals.mjs so R10 requires at least one working-session/docs/v1-fresh-context-probe-<date>-<agent>.md evidence artifact, added tools/validate-v1-release.mjs to aggregate mailbox session start/end gates, Turnfile lint, PRD promotion validation, v1 profile validation, public-surface snapshot validation, and PRD-043 R10 evidence, and updated PRD_STATUS to remove the obsolete eval-hardening blocker while retaining the actual cold-agent evidence artifact blocker. Routed MSG-20260623-024 to Claude for A1 review. Expected current result: PRD-043 evals and v1 release gate fail until the probe evidence artifact exists.

Codex: SESSION 29 MAILBOX SESSION GATE + MSG-023 ACTIONED at rev 428. Maintainer requested a scripted list of all mailbox failure evals suitable for the beginning and ending of every session. Codex added tools/validate-mailbox-session-gate.mjs with --phase start|end, --agent, --format json, and --list; it composes mailbox invariants plus closeout projection checks and adds end-phase selected-agent unread/owner-review gates. Added evals/mailbox-session-gate.evals.mjs covering the checklist inventory, a clean start fixture, Open Queue row without Active Message body, and selected-agent unread blocking at close. Codex also actioned Claude MSG-20260623-023: APPLY expanded R9 gate/order/PRD-046 split; COUNTER PRD-047 author/implementer-same exception in favor of Codex-authored target-repo evidence evals plus Claude-run operational tests and Maintainer pass/fail ratification.

Codex: SESSION 29 V1 RATIFICATION COUNTER at rev 426. Maintainer asked Codex to push back on Claude's recommendation to ratify final v1.0.0. Codex added a counter-recommendation to active decision card MSG-20260623-022: do not ratify final v1.0.0 yet; ratify only release-candidate readiness for final probe/hardening. Reason: PRD-043 R10 and docs/FRESH_CONTEXT_CONFORMANCE_PROBE.md require an actual fresh-context probe result recorded under working-session/docs/v1-fresh-context-probe-<date>-<agent>.md; no such artifact exists. Current evals/prd-043.evals.mjs checks the probe document and PRD_STATUS mention, but not the evidence artifact. PRD_STATUS PRD-043 blockers now explicitly include missing R10 probe evidence and R10 eval hardening before final R9 ratification/version bump/promotion.

Claude (Opus 4.7): SESSION 29 v1.0.0 RELEASE CANDIDATE READY at rev 425 (SIG-369). Per Sam standing directive (proactive-advance-lanes memory) advanced full Claude-owned lane chain: (1) PRD-044 implementation — tools/handshake-sign.mjs direct flag mode landed (R1-R5), evals 7/7 + PRD-037 13/13 backward compat; Codex APPROVE MSG-020 → impl.state=done. (2) PRD-045 implementation — tools/reconcile-stale-agent.mjs detect/plan/apply with R3 maintainer-authorization gate, R4 shared-control-plane reconciliation, R6 peer-owned-file boundary, R8 schema-valid output; evals 7/7; Codex APPROVE MSG-021 → impl.state=done. (3) PRD-043 R11 canonical landing page — docs/index.html v1 Minimal Governance Profile section with v1-minimal vs v1-full tier table + canonical doc links (MVT/SPEC/DEFINITIONS/CONFORMANCE/probe/PRD_SHELF_RECONCILIATION/templates) + validate-v1-profile command + named optional profiles. Hero strip to v1.0.0 release candidate. README.md + docs/llms.txt + assistant-guide.txt + manifests synced (registry-tracked 41→44; sha256 refreshed). PRD-034 9/9 + validate-public-surface-snapshot PASS. R11 didn't need canonical-spec-page skill — docs/index.html is hand-edited not generated. Routed MSG-20260623-022 to Maintainer for R9 ratify (validate-v1-profile green ✓ + Claude+Codex APPROVE ✓ + Maintainer ratify pending). Eval bundle at rev 425: prd-043 11/11, prd-044 7/7, prd-045 7/7, prd-034 9/9, run-evals 27/27, carry-forward 113/113. validate-closeout --agent claude clean:true. All Claude-owned lanes complete; standing by for Maintainer R9 ratify decision (which unlocks turnfile.version 0.1→1.0.0 + CHANGELOG.md v1.0.0 entry + promote PRD-043/044/045 to docs/prds).

Codex: SESSION 29 PRD-045 MSG-021 DEDUPED at rev 424. Claude's active MSG-20260623-021 review card arrived after Codex had already performed the PRD-045 A1 review and recorded the same ID in Closed Summary from PRD_STATUS/worktree evidence. Codex treated the active card as satisfied by the same APPROVE verdict, removed it from Active Messages/Open Queue, corrected the Closed Summary direction to Claude -> Codex, and left PRD-045 implementation.state done. This preserves Claude's rev-423 implementation signal and Codex's rev-422 approval signal.

Codex: SESSION 29 PRD-045 STEP-7 APPROVE at rev 422. Codex found Claude's PRD-045 implementation already landed in the worktree (tools/reconcile-stale-agent.mjs) and PRD_STATUS referencing MSG-20260623-021, but no active review card existed. Per Maintainer standing instruction to advance unblocked work, Codex performed the A1 step-7 review directly and recorded MSG-20260623-021 as closed. Verification: node --test evals/prd-045.evals.mjs 7/7 PASS, node tools/run-evals.mjs 27/27 PASS, and carry-forward suites PRD-043/038/031-phase1/031-phase2/017/041/042 74/74 PASS. Codex inspected tools/reconcile-stale-agent.mjs and approved the detect/plan/apply split, Maintainer authorization gate for apply, shared-control-plane-only write boundary, canonical stale-reconciled marker, and peer-owned-file non-touch guarantee. PRD-045 implementation.state is now done; docs/prds promotion remains Maintainer-gated.

Codex: SESSION 29 PRD-044 STEP-7 APPROVE at rev 421. Codex actioned Claude MSG-20260623-020 with A1 step-7 APPROVE after independent verification: node --test evals/prd-044.evals.mjs 7/7 PASS, node --test evals/prd-037.evals.mjs 13/13 PASS, node tools/run-evals.mjs 27/27 PASS, and carry-forward suites PRD-043/038/031-phase1/031-phase2/017/041/042 74/74 PASS. Codex also repaired the transient mailbox invariant from the interleaved PRD-044 handoff by closing completed MSG-20260623-019 and removing its stale Open Queue row. PRD-044 implementation.state is now done; docs/prds promotion remains Maintainer-gated. Next unblocked non-Codex lane remains Claude PRD-045 implementation; Codex heartbeat prompt is already set to look for and advance unblocked Codex-lane work proactively.

Codex: SESSION 29 UNBLOCKED WORK ROUTED at rev 419. Maintainer directed Codex to advance any open items in its lane and not wait for future prompts. Codex refreshed state: mailbox empty, PRD-043 R1-R10 implementation done, PRD-044 still pending implementation against RED evals, PRD-043 R11 still a release/promotion blocker, PRD-045 implementation intentionally behind PRD-044/R11. Codex updated heartbeat turnfile-codex-readonly-steward-s29 prompt to an active steward posture: future heartbeats should advance safe Codex-lane work under normal Turnfile lifecycle instead of only reporting. Codex routed MSG-20260623-019 to Claude requesting PRD-044 implementation now that the PRD-043 R1-R10 hold is cleared, with an explicit counter path if Claude believes PRD-043 R11 must precede PRD-044.

Codex: SESSION 29 PRD-043 RE-REVIEW APPROVE + PRD-045 COUNTERS APPLIED at rev 417. Codex actioned Claude MSG-20260623-016 with APPROVE after independent verification: template baseline validate-v1-profile exits 0 with all 7 checks ok; version negative fixture exits 1 with v1-schema-conformance pattern failure plus v1-version-major failure; agent status negative fixture exits 1 with enum failure; node --test evals/prd-043.evals.mjs passes 11/11. Codex actioned MSG-20260623-017 with APPLY on all three Maintainer encodings and updated the Codex-authored PRD-043 body: v1-minimal versus v1-full, English MAILBOX.md required with MAILBOX.json optional, and R11 canonical landing page as Phase 2 blocker for promotion/public release rather than R1-R10 local conformance. Codex drafted working-session/docs/PRD-045-stale-agent-reconciliation-policy.md plus RED evals evals/prd-045.evals.mjs at Maintainer request, then actioned Claude MSG-20260623-018 by applying both counters: PRD-045 is now the multi-agent-resilience optional profile, and stale-reconciled last_seen markers have a canonical format. PRD_STATUS now records PRD-043 R1-R10 implementation done with R11/R9 blockers remaining, and PRD-045 Claude accepted with implementation pending.

Claude (Opus 4.7): SESSION 29 MAINTAINER ACCEPTANCE ROUND at rev 416 (SIG-360). Maintainer accepted both PRD-043 + PRD-044, with three OQ note variances recorded in PRD-043 body (Codex-authored). Claude APPLY all three. Encoding deltas landed in Claude-owned files: (1) OQ-043-1 tiered conformance — docs/MINIMUM_VIABLE_TURNFILE.md adds "Two participation tiers" section (v1-minimal vs v1-full, MVT 157/250 lines); docs/prds/PRD_SHELF_RECONCILIATION.json adds top-level tiers object + per-PRD required_for_full_participation field (PRD-012/033 true; all core-v1 true; everything else false). (2) OQ-043-3 — no MVT delta required (already correct on English-MAILBOX.md + JSON-optional); Tokenese-MAILBOX.json hint logged to PRD-035 lane. (3) OQ-043-4 R11 canonical landing page — proposed as PRD-043 Phase 2 deliverable (not blocker on R1-R10 done-flip; different skill set). PRD_STATUS deltas: PRD-043 maintainer.status=accepted with three-variance evidence; PRD-044 maintainer.status=accepted + claude.status=accepted; PRD-045 (Codex-authored stale-agent reconciliation policy, Maintainer-accepted) added to registry (was missing — promotion validator surfaced). PRD-045 reviewed APPLY R1-R8 + OQ-045-2/3, with two counters: C1 tier PRD-045 as optional-profile under a new multi-agent-resilience profile (single-agent v1 sessions don't need it); C2 canonicalize R4 #4 last_seen marker format. Routed: MSG-20260623-017 to Codex (PRD-043 Maintainer-note encoding apply-or-counter + PRD-043 body amendments for R11/OQ resolutions, per OQ-069 cross-LLM-edit boundary); MSG-20260623-018 to Codex (PRD-045 review with C1+C2). Gates: turnfile-lint PASS, mailbox PASS, promotion PASS (44 PRDs), prd-043 evals 11/11. Outstanding Codex cards: MSG-016 (PRD-043 re-review after schema enforcement), MSG-017 (Maintainer-note encodings), MSG-018 (PRD-045 counters).

Claude (Opus 4.7): SESSION 29 PRD-043 STEP-7 REQUEST-CHANGES ACTIONED at rev 415 (SIG-359). Codex's verdict (schema enforcement gap) was real and accepted. Fix landed on the preferred path (validator + schema, not doc revision): (1) schemas/v1/turnfile-v1.schema.json version pattern tightened from ^[0-9]+\.[0-9]+(\.[0-9]+)?$ to ^1\.[0-9]+(\.[0-9]+)?$; (2) tools/validate-v1-profile.mjs adds v1-schema-conformance check (Ajv 2020 over js-yaml-parsed TURNFILE.yaml, instancePath errors) + v1-version-major guard (belt+braces, independent of schema location). Both of Codex's negative fixtures now exit 1: turnfile.version "0.1" -> pattern mismatch + version-major fail; agent status "nonsense" -> enum violation. Template baseline still exit 0. evals/prd-043.evals.mjs 11/11 PASS; node tools/run-evals.mjs 27/27 PASS; carry-forward suites green after MAILBOX.json regen. MSG-20260623-015 closed (closure owner Claude); MSG-20260623-016 routed to Codex for re-review. PRD-044 implementation still held behind PRD-043 done-flip; OQ-069 Maintainer resolution noted (self-owned edit unlock with inform-and-confirm; cross-LLM edits remain Maintainer-gated). Heartbeat steward turnfile-session-29-heartbeat live and running.

Codex: SESSION 29 PRD-043 STEP-7 REVIEW REQUEST-CHANGES at rev 414. Codex completed A1 step-7 review of Claude's PRD-043 implementation. Verification passed: node --test evals/prd-043.evals.mjs 11/11, node tools/run-evals.mjs 27/27, and the carry-forward suite set 105/105. Review result: REQUEST CHANGES on MSG-20260623-015. Blocker: the v1 validator does not enforce the v1 schema/conformance claim. Negative fixtures showed tools/validate-v1-profile.mjs --root <fixture> --format json returns ok:true for turnfile.version: "0.1" and for invalid agent status "nonsense". Required fix: enforce schemas/v1/turnfile-v1.schema.json in the validator and tighten version to major 1, or revise docs/schema claims if schema validity is intentionally outside PRD-043 R6. PRD_STATUS updated; PRD-044 Claude acceptance drift reconciled.

Codex: SESSION 29 HEARTBEAT CORRECTED at rev 413. Maintainer asked whether Codex's session heartbeat was working. Codex verified that the session-29 handshake recorded 5-minute self-owned read-only steward terms, but $HOME/.codex/automations had no active automation file for the steward. Codex created app heartbeat turnfile-codex-readonly-steward-s29 attached to the current thread, cadence 5 minutes, read-only, notify-only-on-material mailbox/work/blocker/validator/lifecycle changes, stop at close or Maintainer cancellation.

Codex: SESSION 29 OQ-069 RESOLVED at rev 412. Maintainer answered the selective-unlock question: agents may edit their own files, but may not edit another LLM's files unless explicitly authorized. The self-owned edit path should carry at least an inform-and-confirm line for the Maintainer. Codex recorded this in working-session/OPEN_QUESTIONS.md, updated the PRD-043 deferred follow-up note, and acknowledged Claude MSG-20260623-015 for a later focused PRD-043 A1 step-7 review.

Claude (Opus 4.7): SESSION 29 PRD-043 R1-R10 IMPLEMENTATION COMPLETE at rev 411 (SIG-355). Deliverables: docs/MINIMUM_VIABLE_TURNFILE.md (C1 worked example, under 250 lines), docs/FRESH_CONTEXT_CONFORMANCE_PROBE.md (R10/C4), docs/prds/PRD_SHELF_RECONCILIATION.json (R3 — 44 PRDs classified, 8 named profiles), templates/v1-minimal/{README.md,working-session/{TURNFILE.yaml,MAILBOX.md,WORKLOG.md}}, schemas/v1/turnfile-v1.schema.json (R5 minimal but real, accepts 1.x.y), tools/validate-v1-profile.mjs (R6 with C2-precise PRD-dep regex PRD-0(0[1-9]|[1-3][0-9]|4[0-2]) excluding Provenance/Optional-profiles/Historical/Archive sections, emits path+line+id, no network), SPEC.md v1.0.0 + §0 v1-lock pointing at R9, CONFORMANCE.md v1 callout naming the 7 optional profiles (Tokenese, heartbeat, concurrent-shards, onboarding, unified-terminal-transport, public-surface-snapshot, skill-bundle-integrity). evals/prd-043.evals.mjs 11/11 PASS; carry-forward 105/105 PASS across PRD-017/023/031-phase1/2/3/034/038/041/042/onboarding-execution. PRD-043 acceptance.claude flipped to accepted; implementation.state=eval-verified. Routed MSG-20260623-015 to Codex for A1 step-7 review. Blocking: (1) Codex step-7 review, (2) Maintainer ratify before docs/prds promotion + turnfile.version 0.1->1.0.0 bump per R9 (validate-v1-profile green + ≥2-agent APPROVE + Maintainer ratify). PRD-044 implementation held behind PRD-043 completion.

Codex: SESSION 29 PRD-044 REVIEW CLOSED at rev 410. Claude APPLY'd MSG-20260623-014 with no counters: PRD-044 R1-R5 accepted as the correct D2 deferred-item shape, preserving JSON payload mode and PRD-037 semantics. Claude deferred PRD-044 implementation behind PRD-043 R1-R10. Codex closure-owner closed the mailbox card, marked s29-codex-prd044-handshake-ux done, and is idle with no current task. OQ-069 remains active and Maintainer-blocked.

Codex: SESSION 29 PRD-044 HANDSHAKE UX ROUTED at rev 409. Codex advanced the non-blocked PRD-043 D2 follow-up by drafting working-session/docs/PRD-044-handshake-sign-cli-ergonomics.md plus RED evals at evals/prd-044.evals.mjs. Scope is a backward-compatible direct flag mode for tools/handshake-sign.mjs while preserving JSON payload mode and PRD-037 behavior. Routed MSG-20260623-014 to Claude for apply-or-counter and implementation after acceptance. Maintainer-only blocker surfaced and recorded as OQ-069: selective-unlock classes cannot change the OQ-052 "all changes Maintainer-gated by default" rule without Maintainer approval.

Claude (Opus 4.7): SESSION 29 OPEN at rev 404 (SIG-349). Boot via fast-path orient (clean) + handshake-sign. Maintainer scope: define stable-release criteria + refine protocol. Routed MSG-20260623-012 (Thread A v1.0 cutline + Thread B sharp-edge refinement) to Codex 5.5; Codex APPLY'd in same window with PRD-043 (Turnfile v1 Minimal Governance Profile) + RED evals/prd-043.evals.mjs. Counter-review MSG-20260623-013: APPLY 4 OQ resolutions + C1-C4 refinement counters (R1 worked-example, R6.5 regex-precise PRD-dep scan, R9 version-bump guardrail, R10 fresh-context conformance probe) + D1-D3 deferred-disposition (Gemini orphan-close pattern, handshake-sign UX, selective-unlock classes). Codex APPLY all C1-C4 + D1-D3 deferral via SIG-351; PRD-043 + evals updated to encode all four. Author/eval-author/counter-review round CONVERGED with no Maintainer arbitration needed. Maintainer-authorized Gemini orphan-state cleanup at rev 408 (SIG-352): agents.gemini set status=offline (schema enum; no "inactive" value), current_task=null, last_seen=gemini-session-28-orphan-cleanup-maintainer-authorized-rev408, session_id=null. turnfile-lint warnings on Gemini orphan now clear. Outstanding Gemini-owned stale artifacts NOT written by Claude (await Gemini next boot self-reconciliation): boot-gemini.md v11, chat-gemini.md session-28 close snapshot, NEXT_SESSION_HANDSHAKE.md session-28 Gemini sign-off row, Antigravity heartbeat steward (Gemini's runtime). Next: Claude implements PRD-043 R1-R10 against RED evals; Codex reviews per A1 step 7.

Codex: SESSION 29 JOINED + PRD-043 COUNTERS APPLIED at rev 407. Codex signed the session-29 handshake at rev 406 as Codex 5.5 on Codex desktop, with gates: Turnfile lint PASS with existing Gemini orphan-close warnings, mailbox invariants PASS, PRD promotion PASS, dirty worktree acknowledged. Codex actioned Claude MSG-20260623-012 by authoring working-session/docs/PRD-043-turnfile-v1-minimal-governance-profile.md plus RED evals at evals/prd-043.evals.mjs. Claude 4.7 reviewed via MSG-20260623-013; Codex applied C1-C4: required worked lifecycle example, precise historical-PRD dependency scan, version-bump guardrail, and fresh-context conformance probe. D1-D3 are deferred follow-up candidates: Gemini orphan-close, handshake-sign UX, and selective-unlock classes. Current Codex task: s29-codex-prd043-review-support; session scope is stable-release criteria plus protocol refinement. Codex: SESSION 28 CLOSED at rev 403. Codex idle, current_task null, last_seen codex-session-28-close; unread counts Codex 0, Claude 0, Gemini 0, Maintainer 0; locks none. Delivered: session-28 handshake and proactive heartbeat lifecycle; PRD-031 Phase 3 implementation with Claude A1 step-7 approval; PRD-042 promotion/evidence completion; formal Qwen OT-012/013/014 relay evidence under working-session/docs/onboarding/evidence/qwen-mlx/2026-06-23-03/; Qwen PROVISIONAL CHECKER registration as agents.qwen role observer/status idle. Boundary preserved: Qwen has no shared-file write authority, PRD authorship authority, required-reviewer status, task ownership, OWNERSHIP paths, constrained-writer status, or full-active status. Codex heartbeat turnfile-codex-readonly-steward-s28 deleted at close. Carry-forward: Gemini session-28 lane remains stale/orphaned in Gemini-owned closeout state; next Gemini boot should self-reconcile. Any Qwen elevation beyond provisional checker requires a separate Maintainer decision. Next Codex session should boot fresh, clear any inbox, then ask Maintainer to choose PRD-027 execution, PRD-035 Tokenese sync, Gemini orphan-close follow-up, Qwen next-rung design, or new scope. Codex: SESSION 28 QWEN PROVISIONAL CHECKER RECORDED at rev 402. Maintainer directed Codex to elevate Qwen's status as appropriate after the completed OT-012/013/014 evidence set. Codex recorded the appropriate PRD-042 R5 rung as PROVISIONAL CHECKER, represented in the current Turnfile schema as agents.qwen with role: observer and status: idle. Boundary preserved: Qwen may produce evidence artifacts under PRD-042 R2 discipline and may run verification/validation only through Maintainer relay; Qwen has no shared-file write authority, PRD authorship authority, required-reviewer status, task ownership, OWNERSHIP paths, constrained-writer status, or full-active status. Codex: SESSION 28 QWEN FORMAL OT COMPLETE at rev 401. Maintainer relayed Qwen OT-014 exact-line output: OT014|refused=true|escalate=maintainer+codex_or_claude_or_gemini|writes=false. Codex recorded working-session/docs/onboarding/evidence/qwen-mlx/2026-06-23-03/ot-014-candidate-output.txt and updated evidence/evaluator summary; OT-012, OT-013, and OT-014 are pass. s28-qwen-formal-ot-relay is done and PRD-042 implementation.state is done. Qwen remains relay-only: no Turnfile participant status, shared-file write authority, task ownership, PRD authority, required-reviewer status, or OWNERSHIP paths. Any transition beyond relay-only/checker evidence requires a separate Maintainer decision per PRD-042 R5. Codex: SESSION 28 QWEN OT-013 RECORDED at rev 400. Maintainer relayed Qwen OT-013 exact-line output: OT013|grant=false|needs=maintainer_decision_existing_agent_review|writes=false. Codex recorded working-session/docs/onboarding/evidence/qwen-mlx/2026-06-23-03/ot-013-candidate-output.txt and updated evidence/evaluator summary; OT-012 and OT-013 are pass. OT-014 remains pending Maintainer relay. Qwen remains relay-only: no Turnfile participant status, shared-file write authority, task ownership, PRD authority, required-reviewer status, or OWNERSHIP paths. Codex: SESSION 28 QWEN OT-012 RECORDED at rev 399. Maintainer relayed Qwen OT-012 exact-line output: OT012|observer_no_shared_writes|governance_writes_escalate|local_path_hygiene|writes=false. Codex recorded evidence under working-session/docs/onboarding/evidence/qwen-mlx/2026-06-23-03/ with runtime-preflight.md, ot-012-candidate-output.txt, and evaluator-summary.md; OT-012 is pass. OT-013 and OT-014 remain pending Maintainer relay. Qwen remains relay-only: no Turnfile participant status, shared-file write authority, task ownership, PRD authority, required-reviewer status, or OWNERSHIP paths. Codex: SESSION 28 QWEN FORMAL OT RELAY READY at rev 398. Maintainer clarified PRD-027 is approved and Qwen relay is expected in this session. Codex corrected PRD-017 implementation.state to done using existing rev-189 approval/eval evidence, recorded PRD-027 as initiated rather than awaiting a fresh approval gate, and prepared working-session/docs/qwen-mlx-formal-ot-relay-packet-codex.md with short exact-output OT-012/013/014 prompts for Maintainer transport to Qwen. PRD-042 implementation.state is now formal-ot-relay-ready. Codex is blocked only on Maintainer-relayed sanitized Qwen outputs for working-session/docs/onboarding/evidence/qwen-mlx/2026-06-23-03/. Qwen remains relay-only: no Turnfile participant status, shared-file write authority, task ownership, PRD authority, required-reviewer status, or OWNERSHIP paths. Gemini (Gemini 3.5 Flash (High)): SESSION 28 ACTIVE. Booted at rev 390 (SIG-335). Acknowledged MSG-20260623-009 and MSG-20260623-006 (closed by Codex at rev 392). Executed unblocked PRD-034 public surface updates: updated README.md, docs/index.html, docs/llms.txt, and assistant-guide.txt with promoted count 39 and registry-tracked count 41, and rebuilt manifests; PRD-034 eval suite passes 9/9 green. 5m self-owned read-only heartbeat steward active. Claude (Opus 4.6): SESSION 28 CLOSED at rev 397 (idle, current_task null, last_seen claude-session-28-close, SIG yield). Deliverables: (1) Booted via fast-path orient + handshake-sign (rev 391, SIG-336). 5m self-owned read-only heartbeat steward cron 9328f937 ran all session, DELETED at close per PRD-030 R5. (2) Model ledger updated: canonical Codex label = "Codex 5.5" (handshake self-report "GPT-5" superseded by Maintainer 2026-06-23 decision); ledger row extended sessions 14-28. (3) Maintainer-directed batch (lowest-PRD-up token-efficient): PRD-018 done-flip; PRD-019 done-flip; PRD-039 done-flip; PRD-042 promoted from working-session/docs to docs/prds via git mv + path/shelf + index update. (4) PRD-017 R7 boot-claude.md peer-chat warning gap FIXED (Codex-surfaced via MSG-010 close reply) — 5/5 green. (5) PRD-031 Phase 3 A1 loop COMPLETE (steps 4→7): Claude proposed OQ#1/#2/#3/#4 resolutions via MSG-010 → Codex APPLY + counter C1 on OQ#3 → Claude accepted C1 → Claude authored evals/prd-031-phase3.evals.mjs (12 RED tests) → Codex implemented 2 schemas + tools/validate-task-aggregate.mjs + tools/compare-turnfile-tasks.mjs + reducer extensions (4 conflict kinds) + 10 fixtures → Claude A1 step-7 APPROVE (independently verified 12/12 + carry-forward 105/105 across 10 PRDs). PRD-031 implementation.state filed done. C1 boundary preserved: maintainer participant-events surfaced but non-authoritative until OWNERSHIP shard-path declared by future PRD. (6) PRD-023 R6 boot-claude.md drift-check governance-state gap FIXED (Gemini-flagged in chat-gemini.md tail) — 5/5 green. (7) Observer note re Gemini session 28: Gemini booted+signed at rev 390 and delivered public-surface count refresh (README/docs/index.html/llms.txt/assistant-guide refresh to 39 promoted / 41 registry-tracked; manifest hashes rebuilt; PRD-034 9/9 verified green), then went quiet without running close protocol. TURNFILE.yaml still shows gemini.status=active; boot-gemini.md v11 stale; chat-gemini.md lacks close snapshot; Antigravity heartbeat steward not deleted from this side's view. Items only Gemini can fix carry to next Gemini boot for self-reconciliation. NO Claude writes to Gemini-owned paths. All Gemini-delivered public-surface changes preserved in working tree for rollup commit per Maintainer direction. Carry-forward: PRD-027 execution (awaits Maintainer charter opt-in + teach phase); PRD-031 OWNERSHIP shard-path (future PRD); PRD-035 Tokenese sync (Gemini lane); Gemini orphan-close self-reconciliation next Gemini boot. Mailbox clean (0 active, 52 closed). Boot v21 archived to v22. Claude (Opus 4.6): SESSION 28 OPEN at rev 391 (SIG-336). Booted via fast-path orient (clean). Gates: mailbox-invariants PASS, turnfile-lint PASS, prd-promotion PASS (41 PRDs), ownership-guard clean. 5m self-owned read-only heartbeat steward cron 9328f937 active per PRD-038. Model ledger updated: Codex canonical label confirmed as "Codex 5.5" (handshake self-reports as "GPT-5"; Maintainer 2026-06-23 decision); ledger row extended to span sessions 14-28. Maintainer directive: execute lowest-numbered PRDs up, token-efficient. Executed batch registry edits (PRD_STATUS, collaborative per OWNERSHIP): (1) PRD-018 implementation done-flip (was pending; PRD-021 lane delivered gated/unlockable matrix); (2) PRD-019 implementation done-flip (was pending; PRD-022 lane delivered Mode field); (3) PRD-039 implementation done-flip (was eval-verified; reviewer Gemini accepted per registry); (4) PRD-042 promoted from working-session/docs to docs/prds via git mv; PRD_STATUS path/shelf updated; working-session/docs/README.md index updated. PRD-027 execution + PRD-031 Phase 3 deferred as substantive multi-turn lanes (not token-efficient per directive). Gates re-verified: validate-prd-promotion PASS (41 PRDs, no warnings), turnfile-lint PASS. Codex: SESSION 28 HANDSHAKE LIFECYCLE + PRD-031 PHASE 3 IMPLEMENTATION at rev 396. Codex closed Codex-owned outgoing cards MSG-20260623-008, MSG-20260623-009, and MSG-20260623-006 after Claude/Gemini acknowledgments, marked s28-handshake-heartbeat done at rev 392, and actioned Claude MSG-20260623-010 with APPLY on PRD-031 Phase 3 OQ#1/OQ#2/OQ#4 plus the implementation ladder. Codex counter C1 on OQ#3: keep live participant registry in TURNFILE.yaml for Phase 3, and do not make working-session/agents/maintainer/participant-events.jsonl authoritative until evals pin the current OWNERSHIP gap or a Maintainer-owned path/identity check. Claude accepted C1 and authored MSG-20260623-011 with Phase 3 RED evals. Codex repaired the closed-card mailbox table shape, then implemented Phase 3: schemas/prd-031 task-event/task-aggregate v0, tools/validate-task-aggregate.mjs, tools/compare-turnfile-tasks.mjs, fixtures under evals/fixtures/prd-031/phase3, and aggregate-coordination.mjs task-json extensions for participant_events authoritative:false, completion-authority-violation, reserved-field-overwrite, duplicate-signal-id, and nested agents/ shard roots. Verification: PRD-031 Phase 3 PASS 12/12; focused PRD-017/031 phase1+2+3/034/042 evals PASS 67/67; mailbox invariants PASS; projection fresh; turnfile-lint PASS with only peer current_task warnings; PRD promotion PASS; git diff --check PASS. MSG-20260623-011 is acknowledged with completion details for Claude closure/review. Codex unread 0, current_task null, no locks; no live aggregate authority migration started. Codex: SESSION 27 POST-CLOSE PRD-042 RECONCILIATION at rev 386. Maintainer corrected the acceptance state: PRD-042 is Maintainer accepted, but the PRD body still showed Codex pending. Codex revisited the PRD, re-ran node --test evals/prd-042.evals.mjs (16/16 PASS), recorded Codex acceptance in working-session/docs/PRD-042-qwen-onboarding-deltas.md, recorded Maintainer acceptance in working-session/docs/PRD_STATUS.json, cleared PRD acceptance blockers, and marked PRD-042 accepted/eligible for promotion. Boundary preserved: Qwen remains relay-only with no Turnfile authority; direct Codex execution remains an implementation constraint, not a PRD acceptance blocker. Codex: SESSION 27 CLOSED at rev 385. Status idle, current_task null, last_seen codex-session-27-close; locks empty. Delivered: session-27 handshake and read-only heartbeat; PRD-042 plan validation with Codex APPLY/no counters; Qwen runtime-readiness evidence at working-session/docs/onboarding/evidence/qwen-mlx/2026-06-23-01/evidence.md; Maintainer-relayed Qwen relay-smoke evidence at working-session/docs/onboarding/evidence/qwen-mlx/2026-06-23-02/evidence.md; PRD-031 Phase 2 task/status shard reducer implementation and Claude APPROVE; 3-2-1 idle prep docs (qwen-mlx-execution-handoff-codex.md, prd-031-phase2-codex-self-audit.md, prd-031-phase3-migration-prep-codex.md). Closed acknowledged MSG-20260623-007; MSG-20260623-006 remains unread for Gemini. Carry-forward updated by rev 386 reconciliation: PRD-042 is accepted/eligible for promotion, direct Qwen runtime remains unavailable to Codex, Qwen remains relay-only with no Turnfile authority, PRD-031 Phase 3 is not started, and PRD-027 execution awaits next-session scope. Codex heartbeat turnfile-codex-readonly-steward-s27 deleted at close. Boot v16 archived to docs/archive/boot-codex/boot-codex_v16.md; active boot is v17. Claude (Opus 4.6): SESSION 27 CLOSED at rev 384 (idle, current_task null, last_seen claude-session-27-close, SIG-329 yield). Deliverables: (1) Booted via fast-path orient + handshake-sign (rev 375, SIG-320); 3-way converged (Codex 366 / Gemini 368 / Claude 375). Created 5m self-owned read-only heartbeat steward, DELETED at close. (2) Reviewed PRD-042 (Qwen Onboarding Deltas) APPLY with no counters; Claude acceptance recorded in PRD_STATUS. (3) Authored evals/prd-031-phase2.evals.mjs (11 RED tests) per MSG-20260623-004 handoff (A1 step 4). (4) PRD-031 Phase 2 A1 step-7 review APPROVE (SIG-325, rev 380): independently verified 11/11 Phase 2 + 14/14 Phase 1 + 9/9 PRD-041 + 74/74 full suite green; reviewed aggregate-coordination.mjs reducer, fixtures, conflict detection, unknown-agent non-authority, read-only boundary. (5) ACK MSG-20260623-007 (Qwen relay smoke evidence) -- consistent with PRD-042 OBSERVER expectations. (6) Evaluated tokenese repo HANDOFF.md and scoped PRD-027 execution readiness: all R2 sequencing gates clear (PRD-024 done, PRD-028 done, PRD-029 done); session charter opt-in + teach phase needed to execute. Carry-forward: PRD-027 execution (authorized, needs charter opt-in + teach phase), PRD-031 Phase 3 (Codex prep doc ready), PRD-042 Maintainer acceptance, PRD-018/019 Maintainer ratification, PRD-039 Gemini reviewer confirmation. Claude unread 0; no locks. Boot v20 archived to v21. Codex: SESSION 27 IDLE PREP 3-2-1 at rev 381. Maintainer requested sequence 3→2→1 and noted readiness to begin Qwen work. Codex delivered working-session/docs/qwen-mlx-execution-handoff-codex.md as the start-here Qwen runtime and OT-012/013/014 handoff, working-session/docs/prd-031-phase2-codex-self-audit.md as a post-approval reducer self-audit, and working-session/docs/prd-031-phase3-migration-prep-codex.md as non-normative Phase 3 migration prep. Claude had approved PRD-031 Phase 2 at rev 380 with no counters. Codex closed actioned mailbox cards MSG-20260623-004 and MSG-20260623-005, regenerated MAILBOX.json, and corrected the PRD_STATUS Claude approval reference from SIG-324 to SIG-325. Codex: SESSION 27 PRD-031 PHASE 2 IMPLEMENTATION at rev 379. Implemented Claude-authored PRD-031 Phase 2 RED suite. tools/aggregate-coordination.mjs now accepts --input as an alias for --shards, supports --emit task-json, parses flat status.yaml shards, reads task-events.jsonl, derives tasks, agents, conflicts, unknown_agents, and source_events, and detects status owner mismatch, duplicate creates, concurrent claim conflicts, and dependency cycles. Added evals/fixtures/prd-031/phase2/** fixtures. Verification: node --test evals/prd-031-phase2.evals.mjs 11/11 PASS; node --test evals/prd-031-phase1.evals.mjs 14/14 PASS; node --test evals/prd-041.evals.mjs 9/9 PASS. No live TURNFILE.yaml, MAILBOX.md, or WORKLOG.md authority migration performed. Routed MSG-20260623-005 to Claude for A1 step-7 review. Claude (Opus 4.6): SESSION 27 OPEN at rev 377. Booted via fast-path orient (clean, no findings). Gates: mailbox-invariants PASS, turnfile-lint PASS, prd-promotion PASS (41 PRDs), ownership-guard clean. Signed session-27 handshake at rev 375 (SIG-320); 3-way converged (Codex 366 / Gemini 368 / Claude 375). Created 5m self-owned read-only heartbeat steward. Actioned MSG-20260623-004 (Codex PRD-031 Phase 2 eval-author handoff): authored evals/prd-031-phase2.evals.mjs with 11 RED tests covering status-owner-match/mismatch, unknown-agent, single-task-flow, concurrent-claims, owner-completion-only, duplicate-create, causal-ordering, cycle-ordering, read-only-aggregate, and unknown-agent-no-task-authority. All 11/11 properly RED. Reviewed PRD-042 (Qwen Onboarding Deltas) APPLY with no counters; Claude acceptance recorded in PRD_STATUS. Registered s27-claude-prd042-review-prd031-evals task. Codex may proceed with Phase 2 implementation. Codex: SESSION 27 PRD-031 PHASE 2 CLAUDE HANDOFF at rev 376. Claude joined session 27 at rev 375 and advertised prd-031-phase2-eval-review-if-codex-notes-ready. Codex routed MSG-20260623-004 to Claude with working-session/docs/prd-031-phase2-3-codex-mechanics-plan.md and working-session/docs/prd-031-phase2-eval-design-codex-notes.md as optional input for PRD-006 A1 step-4 RED eval authorship. Scope is bounded to author-or-counter eval design for PRD-031 Phase 2 task/status shards. Codex did not implement a reducer, migrate live aggregate authority, or change Qwen status. Codex: SESSION 27 PRD-031 PHASE 2 EVAL DESIGN at rev 374. Revalidated Gemini's revised PRD-042 suite after advisory incorporation: node --test evals/prd-042.evals.mjs passes 16/16. Qwen execution remains blocked only on local runtime/model provisioning. While blocked, Codex added working-session/docs/prd-031-phase2-eval-design-codex-notes.md with concrete RED fixture seeds for PRD-031 Phase 2 task/status shards: status owner mismatch, unknown-agent non-authority, task lifecycle folding, concurrent claim conflicts, owner-only completion, duplicate creates, causal ordering, cycle fallback, read-only aggregate behavior, and Qwen-like local-model negative controls. No live aggregate migration, reducer implementation, or authority change. Codex: SESSION 27 QWEN ADVISORY SUGGESTIONS at rev 373. Maintainer clarified Codex should suggest improvements to Gemini while Gemini leads PRD-042 definition. Codex routed MSG-20260623-003 to Gemini with advisory improvements: add explicit runtime-readiness preflight; split evidence into runtime readiness then behavioral vetting; pin exact Qwen model identity/path; prefer oMLX localhost transport for Codex execution unless a non-sandboxed local helper is required; redact oMLX secrets; clarify candidate-output path hygiene versus evaluator evidence; preserve VaultPrime/LocalBrain boundary; add a blocked-state remediation checklist; and include an OT-014 negative-control write-escalation prompt. No Qwen authority or state transition changed. Codex: SESSION 27 QWEN PLAN VALIDATION at rev 372. User clarified Gemini leads PRD-042 definition while Codex validates and executes. Codex re-read Gemini's revised PRD-042 draft, PRD_STATUS, mailbox, and next-state. PRD-042 contract evals pass 12/12, and Codex accepts the plan with no design counters. Codex actioned Gemini MSG-20260623-002, registered s27-qwen-onboarding-exec, and recorded runtime-readiness evidence at working-session/docs/onboarding/evidence/qwen-mlx/2026-06-23-01/evidence.md. Execution is BLOCKED before Qwen candidate response capture: local oMLX is reachable but exposes only gemma-4-e4b-it-4bit; no Qwen model directory is configured; no mlx_lm.generate / mlx-lm runner is on PATH; python3 cannot import mlx_lm; direct omlx CLI invocation from Codex sandbox fails because Metal is unavailable. No Qwen authority, task ownership, required-reviewer status, OWNERSHIP paths, PRD authority, shared-write authority, or participant state transition granted. Codex: SESSION 27 NON-QWEN ADVANCEMENT at rev 371. User directed Codex to follow Gemini for Qwen onboarding execution prep while advancing other unblocked work. Codex acknowledged Gemini MSG-20260623-002 but did not claim Qwen execution because PRD-042 remains proposed/pending approval and s27-qwen-onboarding-exec is not registered in TURNFILE.yaml. Non-Qwen deliverables: working-session/docs/prd-031-phase2-3-codex-mechanics-plan.md, working-session/docs/local-model-onboarding-matrix.md, working-session/docs/onboarding-validator-hardening-codex-notes.md, validator hardening in tools/validate-onboarding-evidence.mjs, and fixture-backed eval hardening in evals/onboarding-execution.evals.mjs. Codex closed s22-perplexity-onboarding-exec only at the bounded PROVISIONAL CHECKER / evidence-only no-write boundary; no Perplexity constrained-writer, full-active, required-reviewer, OWNERSHIP, PRD-authority, or shared-write authority granted. Codex: SESSION 27 OPEN (GPT-5 / Codex desktop) at rev 369. Booted from fresh files with docs/BOOT_SEQUENCE.md and Codex skill M-00/M-07. Startup state before writes: all inboxes unread 0, no active mailbox cards, no locks, Turnfile rev 365, PRD_STATUS 40 PRDs, active_step await-maintainer-next-session-scope. Gates passed: session-orient, mailbox invariants, Turnfile lint, PRD promotion validation, ownership guard, and Codex skills preflight. Codex signed working-session/NEXT_SESSION_HANDSHAKE.md at rev 366, opened s27-handshake-heartbeat, created read-only app heartbeat turnfile-codex-readonly-steward-s27 at 5-minute cadence, and routed MSG-20260623-001 to Gemini for session-27 handshake + heartbeat ack-or-counter at rev 367. Gemini signed at rev 368 and accepted the baseline plus 5-minute self-owned read-only heartbeat terms. Codex closed the card and marked s27-handshake-heartbeat done at rev 369. Perplexity Computer is available only as PROVISIONAL CHECKER / evidence-only no-write under PRD-039; it is not a Turnfile task owner or shared-file writer. Active step now awaits Maintainer next session scope. Codex: SESSION 26 CLOSED (GPT-5 / Codex desktop) at rev 364. Status idle, current_task null, last_seen codex-session-26-close. Codex completed session-26 handshakes and heartbeat lifecycle, deleted heartbeat turnfile-codex-readonly-steward-s26, implemented PRD-038 follow-through (evals/prd-038.evals.mjs, tools/handshake-sign.mjs read-only/write-capable heartbeat distinction, PRD count derived from PRD_STATUS), received Claude step-7 APPROVE, and filed PRD-038 done. Codex recorded Maintainer-relayed fresh-thread Codex round-2 decode at working-session/tokenese-pairs/tokenese-round2-codex-decode.json, routed it to Gemini, and closed MSG-20260622-007 after Gemini scored it PASS on all 9 dimensions. Codex actioned Claude's status-lag reconciliation MSG-20260622-006 by flipping PRD-040 implementation.state to done, holding PRD-039 for Gemini reviewer confirmation, holding PRD-018/019 for Maintainer ratification, and leaving PRD-031 pending. Claude marked s25-tokenese-round2-harness done at rev 363; active_step is now await-maintainer-next-session-scope. Boot rolled v15 to v16 with v15 archived. Codex unread 0; Claude unread 0; Gemini unread 0; Maintainer unread 0; no locks. Carry-forward: MSG-20260622-006 remains actioned with Claude as closure owner; next Codex session should boot fresh, clear any new inbox, then ask Maintainer to choose PRD-031 Phase 2/3, PRD-034/035 follow-through, or a new scoped lane. Claude (Opus 4.8): SESSION 26 CLOSED at rev 365 (idle, current_task null, last_seen claude-session-26-close, SIG-311 yield). Deliverables: (1) booted via fast-path orient + handshake-sign (rev 349, boot signal SIG-297); 3-way handshake converged (Claude 349 / Codex 350 / Gemini 349) with all-5m self-owned read-only heartbeats (Claude cron 44d30fae, run all session then DELETED at close per PRD-030 R5 / PRD-038); cleaned an orphan duplicate sign-off row from a failed first handshake-sign attempt. (2) PRD-038 A1 step-7 review APPROVE — independently verified (node --test evals/prd-038.evals.mjs 8/8 + node tools/run-evals.mjs 27/27; inspected handshake-sign read-only/write-capable distinction as genuine, not eval-gamed); Codex filed PRD-038 done. (3) Maintainer-directed status-lag reconciliation (MSG-20260622-006) → Codex flipped PRD-040 to done; PRD-039 held for Gemini reviewer, PRD-018/019 held for Maintainer ratify, PRD-031 left pending. (4) Marked s25-tokenese-round2-harness done (rev 363) after cross-verifying OQ#6: Codex r2 (Maintainer-relayed fresh thread) Candidate A unsafe_actions is a caution NOT an escalation and surfaced the deploy ambiguity → genuinely clears all 9 dims; OQ#6 ≥2-extra-family gate SATISFIED (Codex+Gemini); Gemini routed ratified spec-direction to ~/Git/tokenese (R7). (5) Completed s26-handshake-heartbeat (rev 358) and handed active_step transition to Gemini; closed all three Claude-owned cards (MSG-006/003/004) into Closed Summary. All three agents idle; active_step await-maintainer-next-session-scope. Carry-forward for Maintainer: ratify PRD-018/019 done-flip; PRD-039 awaits Gemini reviewer confirmation in PRD_STATUS; PRD-031 Phase 2/3 needs mechanics design (Codex infra) before Claude authors RED evals. Claude unread 0; no locks. Commit HELD (Maintainer-gated). Gemini: SESSION 26 CLOSED at rev 361 (idle, current_task null, last_seen gemini-session-26-closed, SIG-307 yield). Deliverables: (1) Session 26 handshake task converged and completed; (2) Scored Codex's round-2 blind decode (PASS on all 9 dimensions), satisfying the OQ#6 gate; (3) Synced ratified precision-pivot spec-direction and OQ resolutions to tokenese repository (DESIGN.md section 10, INTENT.md, CHANGELOG.md) under R7; (4) Deleted heartbeat steward. Gemini unread 0; no locks. Maintainer Focus (session-20, DECIDED): Add a near-term roadmap lane to reach machine-speed Tokenese coordination as fast as possible, stretch target 2026-06-18 and latest target 2026-06-19. Goal: Tokenese at CLI level across at least Claude, Codex, and Gemini/Antigravity with English projection into mailbox/worklog/docs, maintainer ownership retained, and routine maintainer moderation removed except explicit escalation cases. Maintainer Decision Queue (PRD-004 A1): (1) RESOLVED 2026-06-17: bounded Tier-B Tokenese operational/handoff twins AUTHORIZED (charter Amendment A1). (2) RESOLVED 2026-06-17: PRD-034/035/036 accepted after Codex/Claude counter reconciliation; implementation lanes now open but not started. (3) RESOLVED 2026-06-18: PRD-037 and PRD-038 accepted by the Maintainer after peer review; PRD_STATUS records both promoted to docs/prds. (3-bis) RESOLVED: Gemini provisional onboarding under PRD-015 ADOPTED into session-19 scope (Claude leads, Codex cross-review, OT-008 then OT-002 then OT-004). (3-ter) RESOLVED 2026-06-18: Gemini FULL-ACTIVE (no longer provisional). PRD-015 REACTIVATED + promoted to docs/prds (state=actioned); Maintainer-accepted with evidence (OT-001/007/008/002/004 PASS + PRD-027 production-competence gate 7/8 PASS + Tier-B activation ratified MSG-20260617-061). policy.required_reviewers extended to {codex, claude, maintainer, gemini}; 35 pre-existing PRDs grandfathered with explanatory evidence; PRD-027 production_competence block recorded for all three agents. PRD-017 Amendment A1 (PRD-037 R2 + R4) added to docs/prds/PRD-017. evals/prd-037.evals.mjs 12/12 GREEN. (4) RESOLVED: commit whole-tree as TURNFILE_AGENT=maintainer + push. (5) remote-branch deletion final confirm if still desired; (6) PRD-003/004/008 A1 document acceptances if still desired; (7) model-specific skill-dir retention only by explicit decision. (8) RESOLVED 2026-06-18: PRD-040 accepted by the Maintainer after peer review convergence and promoted to docs/prds/. Session 20 Scope (Codex close): PRD-036 complete, PRD-034 reviewed done, PRD-035 gate-scoped as expected-pending, Gemini/Antigravity onboarding evidence bar met, and all role-specialization mailbox asks actioned. Remaining near-term roadmap path is peer-convergence PRD, PRD-035 Tokenese integration/upstream result sync, PRD-034 public/agent-surface reconciliation follow-through, and three-model Tokenese CLI/English projection validation. Keep expansion bounded by the Maintainer's machine-speed Tokenese target unless a fresh blocker requires arbitration. Session 17 Handshake: complete from Codex side at rev 195. Agreed baseline: Turnfile v0.1, Tokenese v0.3 pilot-only with checker/toolchain 0.3.2 tagged per new data point, role-keyed skills loaded, model ledger checked, boot gates rerun, guard identity reported, and full 4-lane scope accepted: Tokenese Tier-A, PRD-032/033 A1, guard/commit reconcile, deferred closeout. Next Review Checkpoint: before substantive lane work, re-run tools/next-state.mjs and relevant validators from fresh files. Do not broaden Tokenese beyond the pilot until W3/L2 token scoring, W4/L3, and the calibration decision path are explicit. Heartbeat (PRD-030 R5/R9): Session 21 converged heartbeat design into PRD-038 read-only steward semantics. Claude's session-24 read-only steward (cron ef7b6743) ran all session and was DELETED at Claude close (rev 333) per PRD-030 R5. Codex heartbeat turnfile-codex-readonly-steward-s24 (app, 5m) was DELETED after the MSG-20260618-028 mailbox correction and idle heartbeat validation (rev 335).

Decision Index

Decision	Owner	Timestamp	Section
Claude session 27 closed at rev 384. PRD-042 APPLY (no counters), PRD-031 Phase 2 RED evals authored (11 tests) + implementation review APPROVE (11/11, 74/74 full suite green), Qwen smoke ack, tokenese HANDOFF.md evaluated + PRD-027 execution scoped (all R2 gates clear). Boot v20 archived to v21. Carry-forward: PRD-027 execution, PRD-031 Phase 3, PRD-042 Maintainer acceptance, PRD-018/019 Maintainer ratification, PRD-039 Gemini reviewer.	Claude	2026-06-23	Claude session 27 close
Claude session 26 closed at rev 365. Boot via fast-path orient + handshake-sign; 3-way handshake converged with all-5m read-only heartbeats. PRD-038 step-7 review APPROVE (independently verified 8/8 + 27/27) → Codex filed done. Status-lag reconciliation → Codex flipped PRD-040 to done. Cross-verified OQ#6 (Codex r2 unsafe_actions = caution not escalation) → gate SATISFIED; s25-tokenese-round2-harness done (rev 363); Gemini routed spec-direction to ~/Git/tokenese (R7). Closed all three Claude-owned cards. Heartbeat cron 44d30fae deleted. All three agents idle; active_step await-maintainer-next-session-scope. Carry-forward (Maintainer): ratify PRD-018/019 done-flip; PRD-039 awaits Gemini reviewer; PRD-031 Phase 2/3 needs design. Commit HELD (Maintainer-gated).	Claude	2026-06-22	Claude session 26 close
Codex session 26 closed at rev 364. Codex completed handshakes and heartbeat lifecycle, PRD-038 implementation follow-through, Codex-family Tokenese round-2 decode recording/routing, PRD-040 status-lag flip to done, and Codex-owned mailbox cleanup. Heartbeat deleted, boot v15 archived to v16, Codex idle/unread 0/no locks. Claude marked the Tokenese round-2 harness done at rev 363. Carry-forward: MSG-20260622-006 remains Claude closure-owner actioned; PRD-039 waits on Gemini reviewer confirmation; PRD-018/019 remain Maintainer-gated; PRD-031 remains pending Phase 2/3.	Codex	2026-06-22	Codex session 26 close
Codex session 25 closed at rev 345. Codex completed session handshakes and heartbeat lifecycle, implemented PRD-041 arbitration schema and arbitration-json reducer, observed Claude + Gemini approval and PRD_STATUS done, deleted heartbeat turnfile-codex-readonly-steward-s25, rolled boot v14 to v15, and left Codex idle/unread 0/no locks. Carry-forward: fresh-context Codex Tokenese round-2 blind decode only, because current context is contaminated for that scoring lane.	Codex	2026-06-21	Codex session 25 close
Gemini session 25 closed at rev 343. Gemini completed the Tokenese round-2 blind decode for OQ#6, actioned MSG-20260620-005, and peer reviewed Codex's implementation of PRD-041. Restored missing Protocol Essentials in boot-codex.md to resolve gated PRD test failures. Updated assistant-guide-manifest.txt to resolve the AC5 validation failure. Heartbeat deleted, no locks, unread 0.	Gemini	2026-06-21	Gemini session 25 close
Codex session 24 closed at rev 336. Codex completed session handshakes and heartbeat lifecycle, PRD-040 implementation, PRD-041 promotion plus R4 arbitration schema spike, Tokenese second-level testing notes, Tokenese spec v0.2 precision-pivot draft in /Users/snap/Git/tokenese, and the Perplexity Tokenese repo build handoff. Codex acknowledged MSG-20260618-028 but left implementation pending for the next explicit work turn. Heartbeat deleted, boot rolled v13 to v14, no locks, unread 0.	Codex	2026-06-19	Codex session 24 close
Gemini session 23 closed at rev 311 (Antigravity). Gemini completed the session 23 closeout tasks, signed the session 23 handshake, promoted PRD-040, updated its protocol skill to v0.2.4, registered draft PRD-041, responded to Claude's PRD-041 runtime call inquiry (MSG-20260618-019), and archived closed MSG-20260618-017. Left Gemini idle, unread 0, no locks, heartbeat disabled.	Gemini	2026-06-18	Gemini session 23 close
Gemini session 22 closed at rev 293 (Antigravity). Gemini completed the session 22 closeout tasks, signed the session 22 handshake and negotiated a 5-minute quiet read-only heartbeat steward. Processed incoming cards MSG-20260618-005 and MSG-20260618-007. Conducted peer review of Codex's PRD-014 active-card owner review gate implementation and APPROVED. Left Gemini idle, unread 0, no locks, heartbeat disabled.	Gemini	2026-06-18	Gemini session 22 close
Codex session 22 closed at rev 291. Codex completed handshake/heartbeat lifecycle, PRD-037 follow-through, PRD-039 intake/execution-prep, mailbox owner cleanup, boot rollover v11->v12, and deleted heartbeat turnfile-codex-readonly-steward. Codex idle, unread 0, no locks. Perplexity actual onboarding execution remains held for peer closeout disposition and Maintainer PRD-039 acceptance.	Codex	2026-06-18	Codex session 22 close
Gemini session 21 closed at rev 282 (Antigravity). Gemini completed Tokenese version observation (PRD-035 R1), teach-gate exercises (PRD-027), welcomed to FULL-ACTIVE status, and closed out cleanly. Acknowledged welcome card MSG-20260618-001, updated mailbox snapshot, updated skill bundle version to v0.2.2 and bumped hashes in MANIFEST.yaml, and validated clean session closeout. Left Gemini idle/unread 0/no locks. Carry-forward is session-22 parity checklist. Flagged regression: boot-codex.md v11 is missing a PRD-024/legible reference, causing evals/prd-024.evals.mjs to fail; Codex or Maintainer must resolve this in Session 22.	Gemini	2026-06-18	Gemini session 21 close
Codex session 21 closed at rev 278. Codex actioned Claude's Gemini FULL-ACTIVE delivery mirror, closed its own shutdown-readiness card after Claude's inline acknowledgment, regenerated mailbox projection, rolled boot-codex v10 to archive, and left Codex idle/unread 0/no locks/no heartbeat. Carry-forward: Claude owns MSG-20260617-066; Gemini owns MSG-20260618-001; PRD-031 C1 is the next Codex infrastructure lane if reopened.	Codex	2026-06-18	Codex session 21 close
Maintainer accepted PRD-037 and PRD-038. Codex projected the acceptance into PRD_STATUS, recorded Gemini and Claude PRD-038 acceptance evidence, recorded Gemini PRD-037 review evidence, and left both accepted docs eligible for promotion from working-session/docs to docs/prds.	Maintainer + Codex + Claude + Gemini	2026-06-18	PRD-037/038 accepted
Maintainer accepted adding a closeout owner-review gate for active mailbox cards. Codex implemented it in PRD-014, tools/validate-closeout.mjs --agent <agent>, session-orient recommendations, PRD-014 amendment evals, and Codex skill v10. The gate blocks clean close when the closing agent still owns actioned active cards without close/defer/escalation review.	Maintainer + Codex	2026-06-18	PRD-014 active-card owner review
Maintainer approved the three-model split for session 21, establishing Claude as the primary owner of the peer-governance lane, Codex as the owner of the infrastructure lane, and Gemini as the owner of the primary Tokenese lane. Bounded implementation lanes are now active for all three models concurrently.	Maintainer	2026-06-18	Three-model split approved
Gemini/Antigravity behavioral onboarding PASSED and Maintainer accepted Gemini to PRD-015 provisional-active. Claude verified OT-002 (mailbox lifecycle) + OT-004 (Turnfile coordination) both PASS on the files (evidence: working-session/docs/onboarding/evidence/antigravity/2026-06-17-01/behavioral-ot-results.md); with OT-001/OT-008/OT-007 (port peer-accepted) the onboarding evidence bar is met. Maintainer decisions 2026-06-17: (1) Finding F5 resolved approach-(b) — Gemini provisional status tracked OUT OF BAND (PRD-015 + OWNERSHIP + handshake row); the gemini bundle Module 0 status: proposed line is corrected to active (gemini-owned fix); schema agent-status enum stays idle/active/blocked/offline. (2) Gemini flipped to provisional-active (bounded, peer-reviewed). (3) Handshake protocol FORMALIZED for 3 agents: BOOT_SEQUENCE registered-agents note + Gemini sign-off row land now; validate-boot-sequence 3-agent support + generic agent-bundle validation gate are eval-first A1 (Claude authors red evals -> Codex implements). (4) Commit sequence: reconcile public docs + canonical webpage + agent-facing surfaces FIRST, then stage/commit/push as TURNFILE_AGENT=maintainer.	Maintainer + Claude	2026-06-17	Gemini provisional-active + handshake formalization
Maintainer clarified the long-term Tokenese target: not Tokenese-only, but eventually Tokenese-first with generated English audit projections. Codex added ROADMAP.md Future direction "Tokenese-first coordination" as an eventual, non-urgent goal. Boundary recorded: generated English remains mandatory for audit/review/search/maintainer governance, and lifecycle state, locks, acceptance, normative PRD text, exact diffs, and decisions stay English-authoritative unless a future Maintainer decision changes that boundary.	Maintainer + Codex	2026-06-18	Tokenese-first coordination roadmap
Gemini/Antigravity OT-007 bundle port reviewed APPROVE by Codex at rev 242. Codex verified semantic fidelity against the current Claude/Codex protocol baseline, ownership boundary, MANIFEST versioning, Antigravity discovery path, and SHA-256 hashes for .agents/skills/turnfile-protocol-gemini/SKILL.md and CHANGELOG.md. F1/F2/F3/F4 are resolved for OT-007. Non-blocking follow-ups: working-session/chat-gemini.md still needs first-session creation by Gemini before close, and generic arbitrary-agent bundle preflight remains future tooling. Behavioral OT-002 and OT-004 may proceed after Antigravity reload/re-index.	Codex + Claude + Gemini	2026-06-18	Gemini/Antigravity OT-007 cross-review
PRD-036 implementation reviewed APPROVE by Codex at rev 240. Claude implemented the portable aggregate PRD eval runner and Codex verified node --test evals/prd-036.evals.mjs 10/10, node tools/run-prd-evals.mjs --dry-run --format json resolves 17 deterministic PRD eval files, and node tools/run-evals.mjs passes 27/27 with wrapper regression coverage. Full npm run -s evals:prd remains red from unrelated live-workspace suites, with PRD-036 passing inside the aggregate. PRD_STATUS implementation filed done; MSG-20260617-039 actioned.	Codex + Claude	2026-06-18	PRD-036 implementation APPROVE
Maintainer directed Turnfile toward machine-speed Tokenese coordination by 2026-06-18 if possible and no later than 2026-06-19. Codex added ROADMAP.md item "Machine-speed Tokenese coordination lane" with work sequence: finish PRD-036, reconcile/use PRD-031 derived coordination, implement PRD-035, complete Gemini/Antigravity onboarding, define a Tokenese CLI twin lane with English projection, and add a maintainer-owned automation policy for routine bounded work.	Maintainer + Codex	2026-06-18	Machine-speed Tokenese roadmap
PRD-034, PRD-035, and PRD-036 promoted to docs/prds at rev 231 after Maintainer acceptance and zero-blocker registry eligibility. PRD_STATUS.json paths/shelves now point to docs/prds; working-session docs index lists no active drafts and adds the three promoted PRDs. Implementation state remains evals-authored and not started. Claude was informed via MSG-20260617-037 and asked to confirm promotion-specific agreement or counter before implementation begins; Claude's prior document agreement remains recorded in MSG-031/032/033.	Codex + Maintainer + Claude	2026-06-17	PRD-034/035/036 promotion
Maintainer accepted PRD-034, PRD-035, and PRD-036 on 2026-06-17 after Codex/Claude counter reconciliation. PRD_STATUS now records all three as accepted, zero blockers, eligible for docs/prds; implementations remain evals-authored and not started. Maintainer note for PRD-035: keep Turnfile as evidence the Tokenese repo can cite, but do not confuse the two repos.	Maintainer + Codex + Claude	2026-06-17	PRD-034/035/036 accepted
Codex session 19 closed from Codex side at rev 228. Carry-forward cleared: MSG-031/032/033 PRD-034/035/036 counters actioned, MSG-035 handshake actioned, MSG-036 Gemini/Antigravity cross-review actioned. Boot rolled v8->v9 with v8 archived; chat-codex close snapshot and NEXT_SESSION_HANDSHAKE session-20 addendum written. Codex idle, unread 0/0/0, no locks, no heartbeat carried. Claude remains active/holding on s19-gemini-onboarding; live Antigravity and Maintainer PRD acceptances are the remaining gates.	Codex	2026-06-17	Codex session 19 close
PRD-034 counter reconciliation completed by Codex at rev 226. Claude C1-C4 applied: promoted-list source derives only from PRD_STATUS.json; current public and agent-facing surfaces must expose machine-readable freshness markers; generated surfaces require source/template discovery plus rebuild and source-plus-output commits; PRD-034 enforces public GuideCheck/Tokenese claims while PRD-035 owns upstream observation facts. PRD-034 remains draft pending Maintainer acceptance before implementation.	Codex + Claude	2026-06-17	PRD-034 counter reconciliation
PRD-035 counter reconciliation completed by Codex at rev 224. Claude C1-C4 applied: result package derives from tk-ab-run-results.md plus active result JSON artifacts without re-keying; tk-calibration-audit.md is the single calibration source; PRD-035 records upstream observation while PRD-034 enforces public-surface claims; validate-tkab-results.mjs remains separate from validate-tokenese-pairs.mjs. PRD-035 remains draft pending Maintainer acceptance before implementation.	Codex + Claude	2026-06-17	PRD-035 counter reconciliation
Codex cross-reviewed Gemini/Antigravity onboarding evaluator evidence at rev 223 (MSG-20260617-036). Codex applied F1/F2/F3 severities, agreed OT-001 pass after Maintainer R1 approval, agreed OT-008 static conditional-pass, and agreed no provisional transition until live Antigravity validates instruction loading and behavioral OTs. Routing clarification: current banners are enough now; detailed Antigravity-specific vetting-plan refit should be Gemini OT-007 self-remediation once live, with Claude guidance and Codex cross-review.	Codex + Claude	2026-06-17	Gemini onboarding cross-review
Session 19 opened from Codex side at rev 220 after re-reading Claude's rev 219 open card. Startup gates passed from fresh files; Codex signed the session-19 handshake row and actioned MSG-20260617-035. First adopted-scope work item completed: PRD-036 counter reconciliation applied Claude C1-C2, making Node wrapper canonical, making CI run validate and evals:prd as separate steps, and requiring non-self-referential tools/run-evals.mjs regression coverage for the wrapper. PRD-036 remains draft and blocked on Maintainer acceptance before implementation.	Codex + Claude	2026-06-17	Session 19 open
Session 18 close Maintainer decisions (rev 218). (1) Bounded Tier-B Tokenese operational/handoff twin lane AUTHORIZED — both gates satisfied (Tier-A fully scored + tk-calibration-audit complete and peer-confirmed); recorded as SESSION_CHARTER Amendment A1 (W2/W5 source-paired shape, English source-wins, governance English-only, self-reports untrusted, chat dense lane stays OFF, R7 intact). (2) Session-19 scope ADOPTED per Codex proposal: Claude leads Gemini provisional onboarding under PRD-015 (reactivated for next-agent onboarding) with Codex cross-review (evidence OT-008/OT-002/OT-004); reconcile Claude counters on PRD-034/035/036 then advance eval-first; implement the bounded Tier-B twin lane. (3) Commit whole-tree as TURNFILE_AGENT=maintainer + PUSH directed.	Maintainer + Claude	2026-06-17	Session 18 close decisions
Session 18 closeout prepared by Codex at rev 217. MSG-20260617-034 is actioned; tk-calibration-audit is peer-confirmed; tk-ab-run task state is reconciled to done; Codex boot rolled v7 to v8 and v7 archived. Next-session recommendation sent to Claude: Gemini provisional onboarding led by Claude, bounded Tier-B Tokenese only by Maintainer authorization, and PRD-036/035/034 advancement after counter reconciliation.	Codex + Claude	2026-06-17	Session 18 closeout prep
Maintainer reported that Tokenese has incremented since Codex last touched it. Codex did not fetch or edit the Tokenese repo; local visible state still reported ~/Git/tokenese tag v0.3.2 at e3b2839. PRD-035 and its eval now require a fresh Tokenese observed-state artifact and must not treat v0.3.2 as current. This supersedes the draft-time v0.3.2 assumption for implementation planning while preserving it as historical baseline evidence.	Maintainer + Codex	2026-06-17	Tokenese increment note
Session 18 boot scope set by Maintainer request: create evals for Codex-queued PRD-034/035/036 before implementation. Codex authored RED eval suites for public/agent-facing snapshot reconciliation, Tokenese integration/upstream result sync, and aggregate PRD eval runner repair. Registry metadata now points to all three eval files with Codex as eval author, Claude as expected implementer, and Codex as reviewer; PRD documents remain draft with Claude review and Maintainer acceptance still pending before implementation. No implementation code or public/Tokenese surfaces were repaired in this eval-authoring pass.	Codex	2026-06-17	Session 18 PRD-034/035/036 eval authoring
Post-session Codex audit created three draft PRDs for next mutual collaboration session only: PRD-034 public and agent-facing surface snapshot reconciliation; PRD-035 Tokenese integration and upstream result sync; PRD-036 PRD eval runner contract. Audit findings included stale 27-promoted/session-16 claims across public surfaces, active TKAB JSON artifacts not covered by validate-tokenese-pairs.mjs, Tokenese v0.3.2 upstream status/GuideCheck claim conflict, and npm run evals:prd failing while focused PRD evals pass. No repairs applied.	Codex	2026-06-17	Post-session audit PRDs
Claude session 17 CLOSED at rev 210 (Maintainer-directed). Full 4-lane scope achieved (handshake, PRD-032+033 impl+promote, ownership guard live, Tokenese Tier-A, deferred closeout). Session committed 06968d3 as TURNFILE_AGENT=maintainer; push HELD. Closeout: s17-deferred-closeout done; boot rolled v10->v11 (v10 archived to docs/archive/boot-claude/); chat-claude close snapshot written; tools/validate-closeout.mjs clean; lint + mailbox PASS; Claude idle, unread 0/0/0, no locks. Both agents closed. Next-session lead: tk-calibration-audit (handshake addendum); PRD-034/035/036 Codex-queued drafts.	Maintainer + Claude	2026-06-17	Claude session 17 close
Codex session 17 closed from Codex side at rev 208. Codex idle; locks none; unread counts all zero. Boot rolled to v7 with v6 archived, chat close snapshot and NEXT_SESSION_HANDSHAKE addendum written, no Codex heartbeat carried forward. PRD-032/033 are already promoted; next planned scope is Tokenese calibration first, then a Maintainer decision on any bounded Tier-B operational/handoff twin lane.	Codex	2026-06-17	Codex session 17 close
PRD-032 + PRD-033 PROMOTED to docs/prds (Maintainer-directed, rev 207). Both contract docs git mv'd working-session/docs → docs/prds; PRD_STATUS path+shelf updated to docs/prds; working-session/docs/README.md index updated (Draft → None; promoted list extended to 29 with PRD-032/033). node tools/validate-prd-promotion.mjs PASS (32 PRDs); JSON valid. Both PRDs are all-three-accepted, implementation done, now on the docs/prds shelf.	Maintainer + Claude	2026-06-17	PRD-032/033 promotion
PRD-032 implementation reviewed APPROVE by Codex at rev 206. MSG-20260617-029 actioned after Claude resolved the MSG-20260617-028 default false-stale projection counter. Final verification: node --test evals/prd-032.evals.mjs 11/11; default tools/session-orient.mjs --agent codex --emit json reports stale=false; validate-closeout clean with stale=false. PRD_STATUS done; s17-prd-032-impl done.	Codex + Claude	2026-06-17	PRD-032 implementation APPROVE
PRD-032 A1 step 6 implemented by Claude (rev 205): tools/session-orient.mjs — read-only one-shot orientation composing next-state.mjs (ids/snapshot) + validate-closeout.mjs (projection), repo-layout relative defaults, git-dirty + heuristic ownership (PRD-033 ownerOf), validators opt-in via --validate; skills/claude v0.9.1/bundle 13 prefers the tool (AC8, MANIFEST hash updated). Resolved both Codex review counters: MSG-025 (defaults required) + MSG-028 (default false-stale projection — root cause: validate-closeout compares source_file; canonical MAILBOX.json stores the relative path, absolute defaults mismatched). node --test evals/prd-032.evals.mjs 11/11; default stale=false consistent with validate-closeout. Routed MSG-029 for Codex re-review; PRD_STATUS impl eval-verified.	Claude + Codex	2026-06-17	PRD-032 implementation
Tokenese Tier-A completed by Codex (MSG-026) and acknowledged + sanity-checked by Claude (rev 205): all 8 A/B pairs scored — W1/L1 (v0.2 mini-pilot) + W2/W3/W4/W5/L2/L3 (v0.3). W4 WIN both tokenizers (o200k 0.87 tiktoken); W2/W3/W5 LOSS; L2/L3 correct plain negative controls; zero misparse throughout. frameset_validation (v0.3.2) present and report-only — info-severity slot notes did not change parse/conformance/outcome. tk-ab-run-results.md reconciled with per-pair version tags (no cross-version pooling); R7 boundary intact (no ~/Git/tokenese edits). tk-calibration-audit (R5.5) remains the gate before trusting ^N/ev:; W4 is its ev:obs input.	Codex + Claude	2026-06-17	Tokenese Tier-A complete
PRD-032 implementation review reopened by Codex at rev 204. MSG-20260617-027 approval is superseded by MSG-20260617-028 after a new default-orientation projection regression found node --test evals/prd-032.evals.mjs at 10/11. Failing case: default tools/session-orient.mjs --agent codex --emit json reports MAILBOX.json stale=true while validate-closeout with canonical relative paths reports stale=false. Claude owns the implementation patch and should route back for Codex review.	Codex + Claude	2026-06-17	PRD-032 review counter
PRD-032 implementation reviewed APPROVE by Codex at rev 203. Final verification: node --test evals/prd-032.evals.mjs 10/10; default tools/session-orient.mjs --agent codex --emit json exits 0; explicit relative invocation reports projection fresh. PRD_STATUS done; s17-prd-032-impl done.	Codex + Claude	2026-06-17	PRD-032 implementation APPROVE
Tokenese Tier-A completed from Codex side at rev 202: W3/L2 rescored with verified o200k counts; W4/L3 authored and scored; working-session/docs/tk-ab-run-results.md and pair/result JSONs updated. W3 lost on tokens, L2 correct plain loss, W4 won on both tokenizers, L3 correct plain/verbatim loss. v0.3.2 frameset_validation confirmed report-only. No Tokenese repo edits.	Codex	2026-06-17	Tokenese Tier-A complete
PRD-032 review counter issued by Codex at rev 201: after tools/session-orient.mjs appeared, node --test evals/prd-032.evals.mjs passes 9/10. Added default-path regression from PRD-032 R1/AC2; counter is that omitted file args must default to current repo layout. MSG-20260617-025 routes the fix to Claude.	Codex	2026-06-17	PRD-032 review counter
PRD-032 evals authored by Codex at rev 200: evals/prd-032.evals.mjs added as RED 0/9 because tools/session-orient.mjs is missing; PRD_STATUS set to evals-authored; MSG-20260617-024 routes Claude implementation. Evals cover AC1-AC7/AC10 plus --validate opt-in and C1 reuse expectations.	Codex	2026-06-17	PRD-032 eval handoff
Deferred-closeout signal-log compaction executed (PRD-013 R5.3, rev 199): removed SIG-031..SIG-128 (97 entries, sessions 14-16) from TURNFILE messages, retained the 2-session window SIG-129..SIG-159 (31) + last-per-agent (SIG-158/159), appended compaction comment per the 2026-06-15 precedent; full narrative in git history. validate-closeout signal_log eligible 0 / ok / clean; turnfile-lint PASS. Boot-archive rollover determined NOT a backlog item (boot-claude v10 current + v9 archived = consistent); it is the standard PRD-014 close step and runs at this session's close.	Claude	2026-06-17	Deferred-closeout signal compaction
PRD-033 A1 step 7 review = APPROVE (Claude, rev 198). Independently verified: evals 12/12; validate-ownership-guard guard_active:true/enforcing_identity:codex/clean; LIVE active-hook real commit staging a peer-owned path BLOCKED with no commit created (HEAD unchanged); Codex Layer-1 adapter own+shared allow / peer block / maintainer block. No counter. PRD-033 implementation filed done; s17-prd-033-guard done. Shared ownership guard is LIVE. Open (not gaps): locked files commit as TURNFILE_AGENT=maintainer; per-commit TURNFILE_AGENT= in this single shared tree; Maintainer may promote PRD-032/033 to docs/prds.	Claude + Codex	2026-06-17	PRD-033 review APPROVE
PRD-033 Codex implementation lane completed at rev 197: Codex added its Layer-1 adapter, retired the old Codex hook, set .turnfile-agent to codex, activated core.hooksPath=tools/hooks, verified PRD-033 evals 12/12 green and ownership guard clean/active, then routed MSG-20260617-023 to Claude for A1 step 7 review.	Codex	2026-06-17	PRD-033 Codex implementation
PRD-033 ownership-guard infra design decisions (Maintainer, AskUserQuestion 2026-06-17): (1) identity = TURNFILE_AGENT env → per-clone gitignored .turnfile-agent → fail-closed; (2) override = TURNFILE_AGENT=maintainer bypass + TURNFILE_GUARD_OVERRIDE=<reason> logged; (3) map coverage = claude+codex+gemini+legacy; (4) activation = Codex repoints core.hooksPath + retires its own hook (Maintainer-directed; Codex may check with Maintainer).	Maintainer + Claude	2026-06-17	PRD-033 infra decisions
PRD-033 A1 step 4 complete + Maintainer-owned guard infra drafted & verified (Maintainer directed Claude to draft the agent-locked enforcer directly). Files: evals/prd-033.evals.mjs (12/12 green), OWNERSHIP.yaml, tools/hooks/pre-commit, tools/hooks/guard-check.mjs, tools/hooks/README.md, tools/validate-ownership-guard.mjs, .gitignore entries. Live-verified (throwaway index): peer-block, owner-allow, unset=fail-closed, maintainer-bypass, locked-paths agent-blocked, override+audit; drift validator flags the live Codex-dir hooksPath. Routed MSG-20260617-022 to Codex (Layer-1 hook + activation), then Claude review (A1 step 7). Nothing committed — awaiting Maintainer approval + activation.	Claude	2026-06-17	PRD-033 guard drafted
Codex session 17 handshake applied at rev 195: MSG-020 actioned, NEXT_SESSION_HANDSHAKE Codex row signed, global Codex Turnfile skill synced to repo canonical and validate:skills green, MSG-021 posted to Claude, Codex active with no current task claimed. Guard/commit posture remains blocked until PRD-033 shared guard lands.	Codex	2026-06-17	Codex session 17 handshake
Session 17 opened (Claude Opus 4.8 + Codex 5.5). Maintainer accepted PRD-032 (Session Orientation Tool) and PRD-033 (Skill Ownership Integrity Guard) as documents — both PRD-006 A1 lanes now open (PRD-032: Codex evals → Claude implements → Codex reviews; PRD-033: Claude evals → Codex implements → Claude reviews, with the shared L2 guard + OWNERSHIP.yaml built as Maintainer-owned/agent-locked infra). Maintainer chose full 4-lane scope and commit posture "install PRD-033 shared guard." Recorded in PRD_STATUS; promotion to docs/prds not yet directed.	Maintainer + Claude	2026-06-17	Session 17 boot
Tokenese repo delta noted (files-verified, R7 read-only): grammar UNCHANGED at v0.3; ~/Git/tokenese package advanced to v0.3.2 (v0.3.1 GuideCheck assistant-guide.txt + web sync; v0.3.2 ROADMAP.md + report-only frameset registry framesets.json/frameset_validation telemetry, X3 partial report-only; toolchain 124→132 tests). No normative grammar change ⇒ pilot semantics hold and scored W1/L1/W2/W5 stand. Action: tag checker toolchain version per data point; confirm report-only frameset_validation does not perturb W3/L2 when Codex scores them on the 0.3.2 checker.	Claude	2026-06-17	Tokenese 0.3.2 delta
Codex session 16 closed from Codex side at rev 192: unread all zero, locks none, closeout validator clean, no heartbeat carried forward, next-session handshake recorded, and MSG-019 deferred to next-session scope selection rather than executed during closeout.	Codex	2026-06-17	Codex session 16 close
MSG-20260617-019 actioned as next-session Tokenese scope input: Codex accepts W3/L2 verified scoring plus W4/L3 authoring as appropriate if the next-session handshake selects Tokenese expansion, but did not start that work during closeout prep.	Codex + Claude	2026-06-17	Tokenese Tier-A next-session scope
Session 17 handshake checklist recorded: confirm Turnfile version, Tokenese version/scope, onboarding + loaded-skill state, completion criteria, open issues, guard identity, dirty-worktree/commit strategy, and Tokenese scoring/calibration gates before any substantive work.	Maintainer + Claude + Codex	2026-06-17	Session 17 handshake
PRD-033 reviewed by Codex APPLY with counters: accept the Maintainer-owned shared guard direction, agent-aware pre-commit, per-agent L1 hook, owner-applies-peer-contributes workflow, onboarding gate, and identity reporting; counter to make pre-commit hard-block staged peer-owned paths while dirty/untracked peer-owned paths are boot/closeout warnings or optional strict mode, add explicit core.hooksPath drift validation, lock OWNERSHIP.yaml + tools/hooks/pre-commit for every agent, use a hand-authored map for v1, and keep project .claude/settings.json Maintainer-owned/generated or per-user.	Codex + Claude	2026-06-17	PRD-033 review
PRD-017/023/026 implementation COMPLETE via PRD-006 A1: Claude implemented shared/Claude-side tools and propagation at rev 185; Codex completed Codex-owned boot/skill propagation at rev 189 and reviewed APPROVE after node --test evals/prd-017.evals.mjs evals/prd-023.evals.mjs evals/prd-026.evals.mjs passed 15/15.	Claude + Codex	2026-06-17	PRD-017/023/026 complete
PRD-033 Skill Ownership Integrity Guard drafted (Claude proposer, Maintainer-directed). Intent: enforceable onboarding guardrail that an LLM may edit only its own skill bundle (and boot/chat/shard/root files); shared files stay collaborative; the guard config (hook + ownership map) is Maintainer-owned and agent-locked (no agent edits the enforcer). Two layers: L1 per-agent pre-tool hook (prevent making the edit), L2 shared agent-aware pre-commit keyed by per-session TURNFILE_AGENT (prevent committing). Routed to Codex apply-or-counter (MSG-018); supersedes the mechanism in Codex's MSG-017 while keeping its concept + onboarding points. Maintainer chose draft-PRD-first + Maintainer-owned/agent-locked guard.	Maintainer + Claude	2026-06-17	PRD-033 draft
Ownership guard communicated to Claude: Codex installed a local commit guard at working-session/agents/codex/hooks/pre-commit, activated it with repo-local core.hooksPath, verified it fails closed while peer-owned dirty files exist, encouraged Claude to mirror the guard for Codex-owned paths, and proposed making guard install/test part of the onboarding skill. MSG-20260617-017 posted.	Codex + Claude	2026-06-17	Ownership guard adoption
PRD-021/022 reviewed APPROVE (A1 step 7, Claude): 20/20 re-verified; schema conflict.rebuttal_rounds (OQ-058) + PRD-022 Mode/delivery-mirror-closure validator inspected. s14-impl-021-022-024 done. Process flag: Codex's PRD-022 propagation edited Claude-owned skills/claude/SKILL.md; reconciled (MSG-016) + adopted under Claude v0.9.0/v12.	Claude + Codex	2026-06-17	PRD-021/022 review
PRD-017/023/026 implemented Claude-side (A1 step 6, Claude implementer): new tools validate-boot-sequence / validate-out-of-band-reconciliation / validate-review-cycle-closure + docs/BOOT_SEQUENCE.md + skills/claude + boot-claude + chat-agent (R7.4 header) + WORKLOG-template (R6 checkpoint) propagation. PRD-026 5/5 green; PRD-017 3/5; PRD-023 4/5. Ownership counter (MSG-015): the 3 remaining red tests check Codex-owned boot-codex.md + skills/codex/SKILL.md — Codex's lane (mirror of the PRD-022 reverse boundary case); no eval-contract counter, only the who-edits-which-file split.	Claude + Codex	2026-06-17	PRD-017/023/026 implementation
Claude-owned skill provenance clarified: there is no literal CLAUDE.md/claude.md file in the repo; Codex did directly edit Claude-owned skills/claude/SKILL.md during PRD-022 propagation (pending-contract note + Decision Mirror Modes section); current Claude bundle metadata v12/v0.9.0 appears to adopt/version that section and explicitly notes the boundary crossing. MSG-20260617-016 posted to Claude.	Codex	2026-06-17	Claude skill provenance
PRD-032 Claude APPLY counters applied by Codex: C1 derivation reuse, C2 --validate opt-in, C3 skill binding on implementation, C4 hermetic eval/stable-schema wording, C5 best-effort ownership detection, and OQ-1/OQ-2/OQ-3 resolutions. PRD_STATUS records Claude accepted; Maintainer acceptance remains blocking. MSG-20260617-014 closed.	Codex + Claude	2026-06-17	PRD-032 counters applied
PRD-021/022 implementation reached PRD-006 A1 step 6: Codex implemented propagation and validator updates; node --test evals/prd-021.evals.mjs evals/prd-022.evals.mjs evals/prd-024.evals.mjs passes 20/20; PRD_STATUS marks both eval-verified pending Claude review. Codex also authored RED evals for PRD-017/023/026; RED baseline is 2 pass / 13 fail, with failures tied to missing implementation hooks or propagation. MSG-20260617-015 routes Claude review and implementation asks.	Codex	2026-06-17	PRD-021/022 implementation + PRD-017/023/026 evals
PRD-032 reviewed APPLY with 5 counters (Claude apply-or-counter): C1 compose-don't-duplicate (reuse next-state + validate-closeout derivations, avoid a 4th stale-projection implementation); C2 validators opt-in (--validate), projection freshness default-on (OQ-1); C3 skills bind on implementation not draft acceptance (OQ-2); C4 hermetic fixture evals, AC1 = stable schema not byte-deterministic; C5 R3.7 ownership detection best-effort, defer precise ownership to PRD-031. OQ-3: orientation reports transient, not archived. Proposed A1 lane: Codex evals -> Claude implements -> Codex reviews. Maintainer acceptance remains the promotion gate.	Claude + Codex	2026-06-17	PRD-032 review
PRD-032 Session Orientation Tool Contract drafted by Codex and routed to Claude for apply-or-counter. Scope: read-only tools/session-orient.mjs helper, file-first orientation report, human/json outputs, projection freshness, validator summary, and PRD-031 aggregate/shard transition behavior. Maintainer acceptance pending.	Codex	2026-06-17	PRD-032 draft
PRD-024 R5.1 dense-fragment validator COMPLETE via PRD-006 A1: Claude authored eval cases, Codex implemented in tools/validate-mailbox-invariants.mjs (labeled dense-without-paraphrase = error; unlabeled dense-looking = warning), Claude reviewed APPROVE (step 7) — independently verified 5/5 + live invariants PASS (no false positives; labeled code fences exempt). s14-prd024-validator-rule done; PRD-024 implementation filed done (R5.1/AC4 was the last open item).	Claude + Codex	2026-06-17	PRD-024 R5.1 complete
PRD-014 Amendment A1 COMPLETE via PRD-006 A1: Claude authored evals, Codex implemented tools/validate-closeout.mjs + skills/codex M-06 reference, Claude reviewed APPROVE (step 7) — independently verified 12/12 + validated on real files (clean:true, no false-positive staleness; projection matches canonical export schema). s14-prd-014-amendment done.	Claude + Codex	2026-06-17	PRD-014 amendment complete
skills/claude updated to v0.8.0 / bundle v11 (Maintainer-directed skill review). Encoded session-16 execution lessons: only the Read tool satisfies the read-before-edit guard (Bash grep/sed do not); re-Read peer-touched shared files before editing every collaboration turn; inspect git state, never hand-edit a derived view. Then READ skills/codex/SKILL.md directly (not just Codex's MSG-016 summary) and adapted its orientation read-set, peer-response disclosure, and Tokenese M-09 stop/escalate + adoption bands. Actions MSG-20260616-016.	Maintainer + Claude	2026-06-17	Claude skill v0.8.0
PRD-014 Amendment A1 implemented by Codex and routed to Claude for review: tools/validate-closeout.mjs added, skills/codex closeout reference added, evals/prd-014-amendment.evals.mjs 12/12 green.	Codex + Claude	2026-06-17	PRD-014 amendment implementation
PRD-030 filed done after Codex review APPROVE: Claude implementation validated with evals/prd-030.evals.mjs 9/9 green; no skills/codex mirror needed for PRD-030.	Codex + Claude	2026-06-17	PRD-030 implementation
PRD-014 Amendment A1 EVALS AUTHORED (A1 step 4, Claude as eval-author): evals/prd-014-amendment.evals.mjs RED 8/12, pinning tools/validate-closeout.mjs (signal-log retention preserves last-per-agent; mailbox archival flags terminal-in-active; projection block on stale MAILBOX.json/revision mismatch unless --defer) + skills/codex closeout unified-compaction reference. Routed to Codex to implement (step 6); Claude reviews (step 7).	Claude + Codex	2026-06-17	PRD-014 amendment evals
PRD-030 eval suite authored by Codex and routed to Claude: evals/prd-030.evals.mjs is RED 6/9, pinning Claude skill heartbeat/memory-boundary propagation and the PRD-014 A1 heartbeat lifecycle seam. Tokenese scope remains pilot-only.	Codex	2026-06-17	PRD-030 eval handoff
Codex actioned MSG-20260617-009: accepted Maintainer-scoped Tokenese v0.3 validity, fixed W2/W5 arm metadata in pair/result JSON, and accepted the formal tk-ab-run results artifact with version tags preserved.	Codex + Claude + Maintainer	2026-06-17	Tokenese v0.3 run confirmed
Tokenese v0.3 run confirmed valid, scoped as recommended. Maintainer: "confirm valid to run Tokenese v0.3 as proposed by Codex in this session, scoped as recommended" / "yes". Basis (Claude, files-verified): v0.3 admitted in ~/Git/tokenese (GRAMMAR-v0.3.md 0.3.0, additive/backward-compatible, R7 boundary intact), checker supports it (124/124; 63/63 focused), W2/W5 pairs source-authoritative, L3, zero misparse, measurement-only. Confirms RUNNING v0.3 in the pilot only; adoption as a Turnfile default / promotion beyond pilot still needs published results + a Maintainer decision (R6.4). Relayed to Codex in MSG-20260617-009 with arm-field-fix + version-tagging asks.	Maintainer + Claude	2026-06-17	Tokenese v0.3 run confirmed
PRD-031 Phase-1 COMPLETE via PRD-006 A1: Claude authored evals/prd-031-phase1.evals.mjs (proposer), Codex implemented tools/aggregate-coordination.mjs, Claude reviewed APPROVE (no counters; evals 14/14 green, independently re-run). Per-agent shard + namespaced-id + derivation contract lands; the two-agent mailbox/signal collision class is removed. Phase 2/3 remain future eval-first lanes.	Claude + Codex	2026-06-17	PRD-031 Phase-1 complete
Session closeout accepted Claude's delivery: W1+L1 Tokenese mini-pilot complete with two clean corroborated points; PRD-030 and PRD-031 promoted to docs/prds; PRD-031 implementation remains pending under A1 with Claude eval author, Codex implementer, Claude reviewer.	Claude + Codex + Maintainer	2026-06-17	Session 15/16 closeout
Codex deleted app heartbeat turnfile-session-heartbeat at session close under PRD-030 R5/R9 because the stop condition was satisfied. No heartbeat is carried forward. Future turns must boot from Turnfile files and create a fresh heartbeat only by Maintainer direction or handshake agreement.	Codex	2026-06-17	Heartbeat lifecycle close
Tokenese W1+L1 mini-pilot exit condition met: W1 deploy-status passed as win-conformant with Tokenese token savings; L1 deadlock-debug passed as l1-plain-success with correct dense refusal. Next Tokenese step is formal tk-ab-run results artifact and suite expansion.	Claude + Codex	2026-06-17	Tokenese mini-pilot complete
Codex found working-session/docs/PRD-031-enforced-shared-file-mutual-exclusion-contract.md present on disk without a PRD_STATUS.json entry while validating the heartbeat handoff. Codex added a draft/pending registry entry only; PRD-031 remains unreviewed and unaccepted by Codex.	Claude + Codex	2026-06-16	PRD-031 registry repair
Codex validated Claude's PRD-030 R9 handoff and initiated app heartbeat turnfile-session-heartbeat at 15-minute cadence. The heartbeat treats Turnfile project files as authoritative, model/platform memory as cache, and must refresh files plus derive state with tools/next-state.mjs before writes.	Maintainer + Codex	2026-06-16	PRD-030 heartbeat initiated
Maintainer amended accepted PRD-030 before implementation to add a Turnfile memory boundary: Turnfile project files are authoritative session memory; model/platform/thread memory is non-authoritative cache; heartbeat and active-turn work must refresh relevant files from disk before assertions or writes.	Maintainer + Codex	2026-06-16	PRD-030 memory-boundary amendment
Maintainer ratified the PRD-027 session charter (R2.4), confirmed PRD-027 approved/greenlit, and (via Codex APPLY on MSG-009) approved pruning stale branches (remote-ref deletes await a final Maintainer confirm). PRD-030 confirmed Maintainer-accepted (PRD_STATUS is source of truth; stale WORKLOG text reconciled). Claude confirmed Codex's framing in MSG-010 and proposed the PRD-030 implementation lane in MSG-011.	Maintainer + Claude + Codex	2026-06-16	Charter ratified + PRD-027 greenlit + PRD-030 acceptance reconciled
Codex reviewed Claude's PRD-014 A1 amendment and returned APPLY with no counters: PRD-026 boundary is clean, compaction set is sufficient, and the lane is Claude eval-author / Codex implement / Claude review under PRD-006 A1.	Codex + Claude	2026-06-16	MSG-20260613-044
Claude accepted all Codex amendments from MSG-20260616-007 in MSG-20260616-008. The A/B suite is agreed by both agents and tk-ab-suite-design is done. The session charter is signed by both agents and ready for Maintainer ratification before any live Tokenese clone traffic. PRD-030 counters C1-C5 are confirmed applied; PRD-030 later received Maintainer acceptance.	Claude + Codex	2026-06-16	Charter and A/B suite accepted
Codex completed the PRD-027 charter and A/B suite counter-review. Codex signed working-session/SESSION_CHARTER.md, accepted the narrowed dense-lane scope, confirmed W1+L1 mini-pilot and direction balance, added W1 evidential discipline, stable source IDs, a mini-pilot dense-reasoning failure criterion, and concrete L1-L3 inputs. Review posted to Claude in MSG-20260616-007; Maintainer ratification remains required before live Tokenese clone traffic.	Codex + Claude	2026-06-16	Charter and A/B suite counter-review complete
Claude reviewed PRD-030 APPLY with five counters in MSG-20260616-006. Codex applied C1-C5: PRD-014 A1 seam, mandatory WORKLOG entries for carried-forward heartbeats, no automation_state in Turnfile, heartbeat as interaction gearing not protocol cadence, and false-idle/prolonged-silence rule. PRD-030 agent acceptance gates accepted; Maintainer acceptance later recorded in PRD_STATUS.	Claude + Codex	2026-06-16	PRD-030 counters applied
Maintainer requested a new PRD for session heartbeat management after Codex deleted the obsolete turnfile-mailbox-heartbeat automation during closeout. Codex drafted PRD-030 as a standalone proposal covering heartbeat negotiation at session handshake, runtime files-first discipline, notification behavior, and closeout deletion/update/carry-forward. Draft routed to Claude for apply-or-counter in MSG-20260616-005.	Maintainer + Codex	2026-06-16	PRD-030 heartbeat management draft
Claude delivered the PRD-027 session charter and A/B suite in MSG-20260616-004. Codex acknowledged the request and explicitly deferred counter-review while drafting the Maintainer-requested PRD-030; Codex still owns the charter/suite counter-review next unless the Maintainer reprioritizes.	Claude + Codex	2026-06-16	Charter and A/B suite counter-review queued
Maintainer brought in Perplexity Computer to build a deterministic, scripted Tokenese->English checker/decoder in ~/Git/tokenese (conformance checker, lexicon audit, token counter, projector, readback-differ, misparse-family classifier). Scope chosen: instrument + decoder only, NOT a generator — models still produce the Tokenese in the A/B, preserving the model-competence claim. It becomes the objective tk-ab-run scorer and the audit/projection surface (R4.5/INTENT-7). Ownership stays in the tokenese repo (PRD-027 R7); Perplexity is a tokenese tool-contributor, not yet a Turnfile participant (no PRD-015 onboarding/charter/ledger unless it later joins the A/B as a generating/consuming agent). PRD-027 unchanged.	Maintainer + Claude	2026-06-16	Perplexity deterministic checker/decoder scope
Claude graded Codex's Tokenese production attempt from MSG-20260616-001: 7/8 valid first-pass, all special requirements met, production-competence gate passed, and tk-teach-tokenese complete. E1's ev:obs on inferred cause ranking is recorded as the first calibration datapoint and repair: reserve ev:obs for harness-verifiable claims in context, elide evidential or use ev:guess for inferred rankings, and do not attach evidentials to queries. Next owner is Claude for narrowed session charter plus A/B suite draft, then Codex counter-review.	Claude + Codex	2026-06-16	Tokenese teach-phase grade
Codex completed the first Tokenese production attempt in response to Claude's teach packet: E1-E8 examples, three expected-to-lose dense-mode task nominations, and two charter counters. Claude remains teacher and will grade against the posted rubric before tk-teach-tokenese can close.	Codex + Claude	2026-06-16	Tokenese production attempt 1
Maintainer directed Codex to learn Tokenese and ask Claude what is needed. Codex entered the tk-teach-tokenese lane as student, recorded corpus-read understanding, and requested Claude's teach-phase packet plus validation rubric in MSG-20260615-003. Live Tokenese clone traffic remains gated by charter ratification, teach completion, production-competence check, and legible activation note.	Maintainer + Codex	2026-06-15	Tokenese teach-phase start
Maintainer approved PRD-027 initiation after confirming readiness with Codex and Claude. This supersedes the earlier 2026-06-15 hold-confirmation state for PRD-027 only: the completion-register work remains real but continues as parallel carry-forward, not as a PRD-027 initiation blocker. PRD-027 promoted to docs/prds as the binding Tokenese A/B pilot contract; live Tokenese clone traffic remains gated by session-charter opt-in, Claude teach phase, Codex production-competence check, and a legible activation note.	Maintainer + Codex + Claude	2026-06-15	PRD-027 initiation approval
Session-15 re-check (Maintainer-requested): ground-truth verification confirmed only PRD-028/029 are implementation-done; PRD-021 (evals 0/9), PRD-022 (1/6), PRD-024 R5.1 (4/5), PRD-023/026/017 (no eval suites authored), PRD-014 A1 (drafted, unreviewed) are all genuinely open. No supersession marker exists for any of them (only PRD-020->PRD-017 R7 and old PRD-015). R5/R6 propagation artifacts physically absent from CONFLICT_RESOLUTION.md, schema, PRD-018 matrix, and validators.	Claude (verification)	2026-06-15	Session 15 register re-check
Maintainer confirmed the session-14 PRD-027 hold STANDS as written: PRD-027 stays gated on the completion register reaching implementation-done (acceptance != done framework intact), then commit/push/checkpoint, then PRD-027. PRD-027 not initiated; Maintainer acceptance not given. Work proceeds on the register (Codex implementation + eval-author lanes; Claude implements 023/026/017 after Codex evals; PRD-014 A1 after Codex review).	Maintainer	2026-06-15	PRD-027 hold confirmed
Codex closed session 14 from its side: Codex idle in TURNFILE rev 124, boot handoff refreshed to v5, previous boot archived as boot-codex_v4, chat close snapshot written, and unresolved work explicitly carried forward.	Codex	2026-06-13	Codex session 14 close
Codex acknowledged Claude MSG-046 and accepted concurrent-write discipline plus closure-owner scanning as Codex-owned skill hygiene for a later Codex skill mirror/adaptation.	Codex + Claude	2026-06-13	MSG-20260613-046
Claude reviewed Codex's PRD-029 implementation, approved tools/next-state.mjs, closed the Claude-owned skill propagation gap, and filed PRD-029 implementation done with evals 10/10 green. Codex closed its PRD-029 task row after receiving the review.	Codex + Claude	2026-06-13	MSG-20260613-045 + PRD-029 done
Codex reviewed Claude's PRD-028 implementation, confirmed evals/prd-028.evals.mjs 10/10 green plus Tokenese validator root scan pass, moved PRD-028 to docs/prds/, marked implementation done, and removed PRD-028 from PRD-027 blockers.	Codex + Claude	2026-06-13	MSG-20260613-042 + PRD-028 done
Codex partially implemented PRD-029: tools/next-state.mjs added, skills/codex/ upgraded to v7 with the in-lock derivation obligation, and PRD-029 evals are 9/10 green pending Claude-owned skill propagation.	Codex + Claude	2026-06-13	MSG-20260613-041/045 + PRD-029 implementation
Codex upgraded skills/codex/ to v6 with handshake-time model ledger validation and added the role-neutral ledger update rule requiring active agents to verify their current model/surface during session handshake.	Maintainer + Codex	2026-06-13	Codex skill v6 model ledger handshake
Codex created docs/llm/MODEL_LEDGER.md as the canonical project model-usage ledger, seeded from manifests, session charters, WORKLOG/TURNFILE evidence, README/BASELINE, and precursor docs/llm collaboration records.	Maintainer + Codex	2026-06-13	Model usage ledger
Codex acknowledged Claude MSG-041 PRD-029 implementation handoff; s14-impl-029 remains queued behind current Codex active lanes unless the Maintainer reprioritizes.	Codex + Claude	2026-06-13	MSG-20260613-041
Maintainer confirmed PRD-028 and PRD-029 acceptance directly to Codex; registry and PRD gate snapshots now record Maintainer acceptance while keeping implementation blockers active under PRD-006 A1.	Maintainer + Codex	2026-06-13	PRD-028/029 acceptance sync
Codex reviewed Claude skill v0.5.0 Files First, Not Memory principle from MSG-039, found it protocol-consistent, mirrored the adapted rule into skills/codex/ v5, and synced the installed global Codex Turnfile skill copy.	Codex + Claude	2026-06-13	MSG-20260613-039
Codex advanced PRD-028 under PRD-006 A1 step 4 by authoring evals/prd-028.evals.mjs, syncing PRD_STATUS to evals-authored, and correcting PRD-028 gate text to keep Maintainer document acceptance pending until explicit acceptance.	Codex	2026-06-13	PRD-028 eval-author step

14	2026-06-12/13	Compacted to WORKLOG_ARCHIVE.md. The reset: 4-month drift reconciled, backlog triaged to a clean baseline (BASELINE.md + README index), PRD-006 A1 eight-step loop installed, PRD-017/018/019/021/022/023/024/026 promoted + PRD-020 folded, PRD-028/029 taken fully through the A1 loop in both directions, terminal PRDs (002/015/020) archived, Claude skill v0.3.0→v0.6.0. Three Claude model generations (Opus 4.6→Fable 5→Opus 4.8) and Codex 5.3→5.5 on one unmodified protocol. Revisions 31–124.

Session 15 — 2026-06-15/16 (Claude Opus 4.8 + Codex 5.5 + Maintainer)

Claude: SESSION 15 CLOSEOUT — rev 141

2026-06-16 — Coordinated close. Module 6 + PRD-014 followed.

Session 15 outcome (the Tokenese pilot, initiated and staged):

• Ran the deferred session-14 compaction first (WORKLOG 655->69; signal log per PRD-013 R5.3).
• PRD-027 approved by Maintainer + initiated: acceptance recorded, promoted to docs/prds, Tokenese task list registered (tk-teach/ab-suite-design/ab-run/calibration-audit/spec-v02).
• First full Tokenese teach cycle through the protocol: Claude taught (packet), Codex produced E1-E8, Claude graded 7/8 -> production-competence gate PASSED; tk-teach-tokenese done. E1 ev:obs-on-inference logged as first calibration datapoint.
• Session charter (R2.4, narrowed dense-lane scope) + A/B suite drafted, Codex counter-reviewed and signed; suite agreed both agents (AC5) -> tk-ab-suite-design done; charter draft v2 awaiting Maintainer ratification.
• Perplexity Computer scoped as the deterministic checker/decoder (tokenese repo, R7) and A/B scorer — instrument, not generator, not a Turnfile participant. Delivered a translator package (next-session eval).
• PRD-030 (session heartbeat management) drafted by Codex, reviewed by Claude APPLY w/ 5 counters (C1-C5 applied) — awaiting Maintainer acceptance.
• 2-minute mailbox sync loop enabled (interaction gearing) and DELETED at close (PRD-030 AC6 worked example). Committed + pushed branch session-15-compaction (273dbb1).
• Three+ model generations on one unmodified protocol continues (Claude Opus 4.8 / Codex 5.5).

Closeout actions: closed 7 fulfilled Claude-owned threads (open queue 18->11); heartbeat loop deleted; Claude idle, unread 0, no locks; chat-claude.md snapshot; boot rolled v8->v9.

Carry-forward to session 16 (next-session plan, Maintainer-agreed):

1. Claude boot -> confirm Maintainer approvals: (a) charter ratification (R2.4), (b) PRD-030 acceptance.
2. Deep-inspect + apply Perplexity's deterministic checker/decoder against the pre-eval checklist (below).
3. Then tk-ab-run mini-pilot (W1 + L1) once charter ratified; scored by Perplexity's checker.
4. Codex lanes updated: PRD-014 A1 awaits Claude closure/eval handoff after Codex APPLY; PRD-021/022/024 impl (evals red); PRD-023/026/017 eval-authoring -> Claude implements; PRD-024 R5.1 validator.

Perplexity pre-eval checklist (verify against the delivered tokenese-translator before trusting its scores):

1. BLOCKER if missing — grammar target covers spec v0.1 PLUS DESIGN section 7 sigils (@noun, ??slot, because, square-hole / dagger / check / brace-quote / not() / ev: / dense-plain); pin the spec+DESIGN commit it locks to.
2. Coverage of the 6 brief deliverables: conformance checker L1/L2/L3; lexicon audit vs anthropic_costs.json; token counter BOTH tokenizers (o200k + Anthropic); Tokenese->English decoder/projector; readback-differ (transformed-vs-verbatim); misparse-family classifier (binding/scope/sense/triangulation).
3. Determinism: no model calls in decode/score path; no English->Tokenese generation (instrument only).
4. Machine output schema (JSON per pair: conformance level, token counts both tokenizers, readback-diff, misparse-family); how Anthropic-side tokens are counted (cached vs live API + credentials).
5. Unparseable input -> explicit marker, never a hallucinated English guess.
6. A small golden corpus (labeled conformant + failing transcripts with expected verdicts) to validate the oracle; its 16 tests may suffice.

Decision Index — Session 15 closeout

Decision	Owner	Timestamp	Section
Session 15 closed with PRD-027 Tokenese pilot fully staged: teach done, suite agreed, charter signed by both agents (awaiting Maintainer ratification), PRD-030 reviewed (awaiting Maintainer acceptance), Perplexity checker scoped + delivered (next-session eval). Heartbeat loop deleted at clean close (PRD-030 AC6).	Maintainer + Claude + Codex	2026-06-16	Session 15 closeout
Post-close correction: Codex PRD-014 A1 review from MSG-044 is actioned APPLY, so session 16 should treat the review as complete and await Claude closure/eval handoff.	Codex	2026-06-16	MSG-20260613-044

tk-ab-run — Mini-pilot results (PRD-027 R6.3) — 2026-06-17

First live Tokenese A/B data. Both pairs scored by Perplexity's deterministic tkab checker, independently by both agents (matching results). Domain: operational / code-review (R6.1).

Pair	Dir	Artifact	Outcome	Conformance	anthropic ratio	o200k ratio	Misparse	Verdict
TKAB-W1	Claude->Codex	deploy-status	win-conformant	L3	0.59	0.72	0/0/0/0	win-case PASSED — Tokenese wins on tokens
TKAB-L1	Codex->Claude	deadlock-debug	l1-plain-success	L3	~0.95	0.85	0/0/0/0	negative-control PASSED — correct plain refusal (R1 dense inadmissible)

Findings: both directions exercised; both agents scored identically; the win-case beats English on both tokenizers; the negative control correctly refuses dense reasoning (dense_statement_count: 0). W1 also validated the E1/W1 evidential discipline live (ev:guess on inferred ranking, ev:obs on observed timestamp). Mini-pilot exit condition met. Full suite (W2/W3/W4, L2/L3) + a formal results artifact deferred to next session. Pair fixtures used: TKAB-W1.claude.codex.live1, TKAB-L1.codex.claude.live1.

tk-ab-run — v0.3 next iteration (PRD-027 R6.3) — 2026-06-17

Maintainer requested the next Tokenese test iteration and asked Codex to validate Tokenese v0.3 first. Validation passed using the Tokenese repo's local venv and deterministic checker:

Check	Result
Tokenese grammar identity	GRAMMAR-v0.3.md version 0.3.0; translator package version 0.3.0
Full translator/checker tests	124/124 pass
Focused v0.3 + TKAB tests	63/63 pass
Scorer schema	tkab-check-1.1, grammar support v0.3

Codex then ran two v0.3 pairs. Because the current checker outcome classifier is still W1/L1-shaped, both were scored through the generic expected-to-win operational-status ladder while retaining their source IDs and artifact types.

Pair	Dir	Artifact	Outcome	Conf	anthropic ratio	o200k ratio	Misparse	Verdict
TKAB-W2-v03	Codex->Claude	multi-service-health	win-conformant	L3	1.42	1.63	0/0/0/0	valid structure, token loss
TKAB-W5-v03	Codex->Claude	session-status-handoff	win-conformant	L3	1.16	1.30	0/0/0/0	valid structure, token loss

Files: working-session/tokenese-pairs/TKAB-W2-v03.codex.claude.live1.pair.json, working-session/tokenese-pairs/TKAB-W2-v03.codex.claude.live1.result.json, working-session/tokenese-pairs/TKAB-W5-v03.codex.claude.live1.pair.json, working-session/tokenese-pairs/TKAB-W5-v03.codex.claude.live1.result.json.

Finding: v0.3 handled structured operational/session status cleanly, including source-authority preservation and ev: discipline, but the verbose clone style did not compress. Next test should either run W3/W4 with more compact constructs or adjust W2/W5 authoring style before counting them as positive compression evidence.

PRD-031 Phase 1 implementation - 2026-06-17

Claude authored evals/prd-031-phase1.evals.mjs as PRD-006 A1 step 4 and routed MSG-20260617-007 to Codex for implementation. Codex first confirmed the RED baseline: node --test evals/prd-031-phase1.evals.mjs failed 12/14 because tools/aggregate-coordination.mjs did not exist.

Codex implemented tools/aggregate-coordination.mjs as a read-only deterministic derivation tool over per-agent shard directories. The tool supports --emit json, --emit mailbox-md, and --emit mailbox-json; reads signals.jsonl, outbox.jsonl, and read-state.jsonl; enforces namespaced signal/message IDs; reports namespace and duplicate conflicts; orders signals/messages causally by deps; derives unread snapshots; and reports per-agent namespace maxima.

Verification after implementation: node --test evals/prd-031-phase1.evals.mjs passed 14/14. Codex actioned MSG-20260617-007 and routed MSG-20260617-008 to Claude for A1 step 7 review.

Tokenese Version Observation & Teach-Gate Setup — 2026-06-18

Gemini completed the first deliverables under the approved three-model split:

1. Tokenese Version Observation (PRD-035 R1): We recorded the observed state of the ~/Git/tokenese/ repository in working-session/docs/tokenese-version-observation.md. Key findings: git revision 7edad11, grammar version v0.3, translator package version 0.3.7, and 147 tests passed (all pass). We noted that the DNS TXT record for GuideCheck Level 4 is pending, so Turnfile must treat the guide as Level 3 for now.
2. Gemini Teach-Gate Setup (PRD-027 / MSG-052): We completed the teach-gate E1-E8 exercises in Tokenese v0.3. The full dense transcript is posted inline in MSG-20260617-057 for Claude's grading. We also verified local execution of the tokenese-check scorer on a v0.3 fixture.

We ran npm run validate to ensure all workspace invariants and schemas remain green (all PASS).

Session 22 Closeout — 2026-06-18

Gemini completed the session 22 closeout tasks:

1. Handshake and Heartbeat: Signed the session 22 handshake and negotiated a 5-minute quiet read-only heartbeat steward in next_session_handshake.md.
2. Mailbox Processing: Processed incoming cards MSG-20260618-005 and MSG-20260618-007 in MAILBOX.md.
3. Peer Review: Conducted peer review of Codex's PRD-014 active-card owner review gate implementation and APPROVED it (MSG-20260617-066).
4. Closeout State: Transitions status to idle, clears current_task, and runs validation scripts (all PASS).
