# Codex Report — 2025-10-10T00:32:41Z

## Objective
- Audit recent "docs/aicode" codex reports and the latest commit history to ensure `AGENTS.md` reflects current project status.
- Apply the minimal necessary documentation update without disturbing established contributor guidance.
- Record the investigation and resulting maintenance actions for future agents.

## Materials Reviewed
- `git log -5 --oneline` (commits `9e073ca`, `6fc153c`, `4952510`, `52f859a`, `f2e1704`).
- `git show 9e073ca --stat` and `git show 6fc153c --stat` for change summaries touching the RDF export pipeline and tests.
- Codex reports: `gpt-5-codex-report-20251009T235749Z.md`, `gpt-5-codex-report-20251009T123258Z.md`, and `gpt-5-codex-report-20251009T121500Z.md` for the evolving DrawIO pipeline narrative.
- Repository root `AGENTS.md` (scope-wide instructions and task ledger).

## Actions
1. **Repository context** — Reviewed the most recent commits and reports to confirm that the Turtle export alignment and rdflib isomorphism regression harness landed on 2025-10-09.
2. **Guidance validation** — Checked `AGENTS.md` to verify task statuses and historical notes, confirming Task 4 Phase 1 completion while Phase 2 remains pending.
3. **Documentation refresh** — Appended a historical-context sentence referencing commit `9e073ca` so contributors know Bun now houses the isomorphism checks guarding Pyodide outputs.
4. **Traceability** — Authored this codex report to document the auditing process, rationale for the minimal edit, and the resources consulted.

## Testing
- Documentation-only update; no automated tests were run.

## Follow-up Notes
- Future contributors extending Phase 2 of Task 4 must keep the Bun isomorphism harness synchronized with the Python reference workflow introduced in commit `9e073ca`.
- The instruction to run `bun run check` remains in force from `AGENTS.md`; honor it before future commits that touch executable code.
