# Codex Report — 2025-10-10T02:00:45Z

## Objective
- Re-audit the last 48 hours of DrawIO RDF export work to confirm `AGENTS.md` captures every milestone leading to the current Turtle-first workflow.
- Trace the recent commit history (`4952510` → `6fc153c` → `9e073ca`) alongside contemporaneous codex reports to verify narrative coverage and testing expectations.
- Update contributor guidance only where fresh context is missing, preserving all existing instructions.
- Record this deeper inspection and documentation alignment for future maintainers.

## Materials Reviewed
- `git log --oneline --decorate --max-count=10` to reconstruct the sequence of recent commits on `work`.
- Detailed diffs for commits `4952510`, `6fc153c`, and `9e073ca` via `git show --stat`.
- Codex reports within the last 48 hours:
  - `gpt-5-codex-report-20251008T180943Z.md`
  - `gpt-5-codex-report-20251009T045342Z.md`
  - `gpt-5-codex-report-20251009T121500Z.md`
  - `gpt-5-codex-report-20251009T123258Z.md`
  - `gpt-5-codex-report-20251009T235749Z.md`
  - `gpt-5-codex-report-20251010T003241Z.md`
- Repository root `AGENTS.md` (scope-wide guidance).

## Actions
1. **Timeline reconstruction** — Cross-referenced commit metadata with the codex narratives to map the flow from the experimental Turtle download spike (`4952510`) through the stabilization of mock black box coverage (`6fc153c`) to the final Turtle metadata/isomorphism hardening (`9e073ca`).
2. **Guidance gap analysis** — Compared the reconstructed sequence against the existing historical context paragraph in `AGENTS.md`, identifying that the transitional `6fc153c` commit was absent.
3. **Targeted documentation update** — Appended a single clarifying sentence to the historical context summarizing how `6fc153c` reconciled Pyodide integration with restored Bun tests after the `4952510` spike.
4. **Traceability logging** — Authored this report to capture investigative steps, references consulted, and resulting documentation adjustments.

## Testing
- Documentation-only edits; no automated test suites were executed for this task.

## Follow-up Notes
- When Task 4 resumes, treat the `6fc153c` checkpoint as the safe baseline for exercising Bun coverage while toggling Turtle defaults.
- Future documentation refreshes should continue walking backward through codex reports until every newly cited commit already appears in `AGENTS.md` history.
