FIX7 P0 Codex Workspace Evidence Sync — Report

• Authority: EVIDENCE_BUNDLE_NON_AUTHORITY. Access-packaging only; authorizes nothing; mutates no production.
• Host: T1 / CLAUDE CODE / MYTHOS · Date: 2026-06-11
• Macro: FIX7_P0_CODEX_WORKSPACE_EVIDENCE_SYNC_REPAIR_MACRO_2026_06_11
• Final status: FIX7_P0_CODEX_WORKSPACE_EVIDENCE_SYNC_READY

1. Problem

Codex returned CODEX_FIX7_P0_DRYRUN_EXECUTION_READINESS_REVIEW_BLOCKED twice. Cause was an evidence-access failure, not a content rejection: the review evidence bundle root and its six entry files were not visible in Codex's review workspace, and Agent Data MCP had a handshake timeout, so content review never started.

2. What this macro did

Materialized the existing KB evidence bundle (knowledge/dev/reports/architecture/fix7-p0-codex-review-evidence-bundle-2026-06-11/, tree 1b824b911bdbc9cce43280f288abd702aebb42211b59ffbff253c2d06533ab26) into a Codex-readable local workspace capsule that requires no MCP to start, and proved the root + entry files exist locally and are byte-identical to KB before Codex is asked again. Codex was NOT re-asked.

• Workspace capsule (absolute): /Users/nmhuyen/codex_review_evidence/fix7-p0-dryrun-execution-readiness-2026-06-11/
• Workspace capsule (relative): codex_review_evidence/fix7-p0-dryrun-execution-readiness-2026-06-11/

3. Capsule contents (16 files + _external/ scaffold)

Mirrored bundle (13 files, byte-exact, tree 1b824b91…3ab26): README_FOR_CODEX.md, REQUIRED_READ_ORDER.md, EVIDENCE_PATH_MAP.json, EXPECTED_HASHES_AND_TREES.json, RECONSTRUCTION_COMMANDS.md, CODEX_BLOCKED_REVIEW_DIAGNOSIS.md, MISSING_OR_UNREADABLE_PATHS.json, manifest.json, commands.sh, RERUN.sh, exit_codes.json, HASH_MANIFEST.txt, packet_tree.sha256.

Workspace-only access-check artifacts (3, authored by this macro; intentionally not in the bundle HASH_MANIFEST.txt so the mirrored tree stays 1b824b91…3ab26): LOCAL_ACCESS_CHECK.md, LOCAL_ACCESS_CHECK.json, RERUN_LOCAL_ACCESS_CHECK.sh.

_external/ holds the 3 KB-fetched external HASH_MANIFEST.txt (dryrun/planning/seal) used by RERUN.sh for the fresh-from-KB external tree re-verify.

4. Proof (all PASS)

• test -d capsule root → PASS.
• test -f six entry files → PASS (6/6), each sha256 equals the KB manifest:
  • README_FOR_CODEX.md 68446059…e9762
  • REQUIRED_READ_ORDER.md 19f486c9…fd62f
  • EVIDENCE_PATH_MAP.json b705340d…9812a
  • EXPECTED_HASHES_AND_TREES.json b4c360ba…e266e
  • RECONSTRUCTION_COMMANDS.md 2c0e3e02…45b4b
  • CODEX_BLOCKED_REVIEW_DIAGNOSIS.md e95d9b22…958a6
• shasum -a 256 -c HASH_MANIFEST.txt (11 bundle files) → all OK.
• bundle packet_tree recompute = 1b824b91…3ab26 == recorded == known KB tree → PASS.
• bash RERUN_LOCAL_ACCESS_CHECK.sh → LOCAL_ACCESS_CHECK_RESULT: PASS (exit 0).
• bash commands.sh → OVERALL PASS (exit 0).
• bash RERUN.sh (with _external/*) → RERUN_RESULT: PASS (exit 0); external trees recompute byte-exact to 02b200e5…94e6 (dryrun), f470d0d0…0fe8f (planning), 3890cd34…12a234 (seal).
• Codex can start from local README_FOR_CODEX.md without MCP → YES.

5. Honesty

• Codex blocked-review OUTPUT artifacts not found in KB: 3 — recorded as CODEX_BLOCKED_REVIEW_ARTIFACT_NOT_FOUND_IN_KB, not fabricated (they are the blocked review's output, never published; not required inputs for the re-run).
• Required review-input artifacts unreadable: 0.
• No claim of Codex PASS. No claim of execution authorization.

6. Boundary (all NO)

Production mutation: NO. Implementation execution: NO. REAL_RUN/QT001/apply/permit/activation/ repoint/cutover: NO. N7/N8/P7 altered: NO. Dry-run verdict altered: NO (READY_FOR_OWNER_EXECUTION_REVIEW stands). Registry/index folded: NO. Codex re-asked: NO. PG/Directus/registry-row/system_issues mutated: NO.

7. Object allocation

TKT-OBJ-413..417 PROPOSED, standalone governance addendum, APPLY_NOW=NO, above ceiling 412 (no canonical registry JSON / 00-index fold). See fix7-p0-codex-workspace-evidence-sync-governance-addendum-2026-06-11.md.

8. Remaining blocker + next Codex entry point

• Blocker FIX7-P0-CODEX-REVIEW-ROUTE-1 (carried): owner routes the re-review. Production NOT blocked by this macro; the access blocker is now closed on the workspace side.
• Exact next Codex entry point: point Codex at the local capsule and start at /Users/nmhuyen/codex_review_evidence/fix7-p0-dryrun-execution-readiness-2026-06-11/README_FOR_CODEX.md, then follow REQUIRED_READ_ORDER.md. No MCP listing/search is needed to begin; KB fetches (if available) only confirm the already-pinned external trees.
