# Malformed CURIE Detection Enhancements – Worklog (2025-10-20)

## Overview
- Tightened `DrawIOXMLTree._extract_individual_and_arrow_and_literal_cells` override so literal detection requires the absence of a containing mxCell.
- Ensured malformed rdf:type values (missing prefix separator, empty prefix, or empty reference) now reliably raise `NotInKnownException` instead of being treated as literals.
- Verified regenerated parser surfaces the override and retains absolute-IRI handling in downstream serialization.
- Confirmed extended AA37 mock fixture exercises colon-only, dangling prefix, and missing prefix scenarios.

## Key Changes
1. `legacy/overrides/curie_validator.py`
   - Track the immediate parent id for each mxCell and classify literal candidates only when they lack a parent box (`parent` of `1`).
   - Preserve the new malformed rdf:type checks (missing separator, empty prefix, empty reference, unknown prefix) with detailed error reporting.
2. `legacy/draw_io_parser.py`
   - Regenerated from overrides to capture the literal classification tweaks.
3. Tests/Fixtures
   - Reran pytest suite targeting patched parser behaviours (`legacy/tests/test_patched_parser.py`).
   - Exercised Bun-integrated regression pipeline via `bun run test` and `bun run test:log:linux` (log captured under `tests/demo_logs/test.log`).

## Testing Summary
- `bun run check`
- `pytest legacy/tests/test_patched_parser.py::test_parse_drawio_rejects_malformed_type_variants -vv`
- `pytest legacy/tests/test_curie_validator.py -q`
- Full `bun run test`
- `bun run test:log:linux` (log archived)

All checks succeeded; malformed rdf:type variants now raise as intended.
