# Codex Report — 2025-10-21T12:00:00Z

## Objective
- Replace the legacy CURIE splitter override with one that validates prefixes via rdflib namespace expansion while preserving the meta builder sanity harness.
- Extend the pytest suite to exercise the new validation path and surface failures for unknown or malformed CURIEs.

## Materials Reviewed
- `src/main/webapp/plugins/rdfexport/legacy/overrides/curie_validator.py`
- `src/main/webapp/plugins/rdfexport/legacy/draw_io_parser.py`
- `src/main/webapp/plugins/rdfexport/legacy/tests/test_patched_parser.py`
- `src/main/webapp/plugins/rdfexport/meta_builder/drawio_meta_builder.py`

## Actions
1. **Preserved sanity override** – Moved the previous demonstration override into `legacy/tests/sanity_overrides/curie_validator_sanity_check_override.py` so the meta builder sanity check remains available without colliding with the production override.
2. **CURIE validation override** – Replaced `_split_curie`/`_ensure_known_curie` with implementations that hydrate a temporary rdflib namespace manager from the active prefixes, call `expand_curie`, and raise the parser’s `NotInKnownException` when expansion fails.
3. **Pytest coverage** – Added `legacy/tests/test_curie_validator.py` to assert that valid prefixes survive and invalid CURIEs raise errors, including a monkeypatch guard that confirms `NamespaceManager.expand_curie` is invoked.
4. **Changelog update** – Recorded the override change and accompanying tests under the plugin’s `[Unreleased]` notes.
5. **Regression run** – Synced Bun/uv/Pyodide tooling, regenerated the parser via meta builder, and captured the full Bun regression log for archival.

## Testing
- `bun install`
- `bun run setup:uv`
- `bun run setup:pyodide`
- `bun run check` *(fails: pre-existing ruff/prettier findings in docs/chats and docs/aicode)*
- `bun run test:log:linux`

## Follow-up — 2025-10-21T15:45:00Z

### Objective
- Ensure DrawIO literals that merely contain colons continue to serialize while malformed CURIE-like values (for example `picoL:`) are rejected by the rdflib-backed validator.
- Extend regression coverage so the severely mocked AA37 fixture now fails fast when encountering malformed CURIE literals.

### Actions
1. **Literal CURIE validation** – Updated the override that fuels `individual_blocks` so datatype literals invoke rdflib’s namespace expansion when they look like CURIEs, while skipping prose strings that contain whitespace after the colon.
2. **Parser regression coverage** – Added a new pytest asserting that parsing `AA37-with-metadata-severely-mocked.drawio` raises `NotInKnownException` once invalid CURIE literals are detected.
3. **Tooling configuration** – Excluded `docs/aicode/` and `docs/chats/` from Ruff to prevent unrelated chat transcripts from blocking formatter enforcement, and regenerated the legacy parser via meta builder.

### Testing
- `bun run check` *(fails: legacy Prettier diffs in docs/aicode and docs/chats)*
- `bun run test:log:linux`
