Codex Report — 2025-10-09T12:15:00Z

Objective

  • Restore AGENTS.md to its pre-2025-10-09 revision and layer in only the essential clarifications requested by the latest stakeholder guidance.

  • Cross-check every docs/aicode/ report and the historical commits on the feat/rml branch to ensure the contributor plan reflects shipped work and outstanding gaps.

  • Capture the investigative steps and resulting adjustments for future agents.

Materials Reviewed

  • git log --oneline --decorate --graph --all | sed -n '1,160p' to trace feat/rml milestones (plugin introduction 1e4582a, CSV panel commits 1ba6e28/a519ecf, deterministic fixture sweep 5d2b0fb, map schema refactors f2034d1, metadata parser updates a28a81a, mock black box wiring 800c937/17c898f, etc.).

Actions

  1. Recovered baseline plan: Checked out the AGENTS.md snapshot from commit 8ea7107 (pre-rewrite) to satisfy the rollback requirement.

  2. Historical reconciliation: Correlated the feat/rml commit log with the codex narratives to verify which stages are complete (plugin bundling, CSV/base URI controls, metadata-aware parser, baseline regeneration tooling, mock black box) and which remain pending (Task 3 helper extraction, Pyodide integration).

  3. Minimal augmentation: Injected a concise “Historical context” paragraph and an operational tooling bullet into AGENTS.md so it references the confirmed branch history and the documented dependency/test workflow without reintroducing the larger rewrite.

  4. Documentation: Logged this investigation and the resulting edits in this report for traceability.

Testing

  • Documentation-only updates; no automated tests executed.

Follow-up Notes

  • When Task 3 begins, ensure the extracted helpers and their regression plan are aligned with the baseline regeneration utilities introduced in late feat/rml commits.

  • If Pyodide integration work resumes, reuse the mock black box hook preserved throughout the branch to avoid disrupting Bun regression hashes.
