# RDF Export Override Update Report

## Context
- **Agent:** gpt-5-codex
- **Date (UTC):** 2025-10-23 16:42:23
- **Task:** Recognize bare IRIs on arrow labels with the same reliability afforded to individual nodes while honouring repository contributor workflow requirements.

## Summary of Work
1. Executed required setup steps inside `src/main/webapp/plugins/rdfexport/`:
   - `bun install`
   - `bun run setup:uv`
   - `bun run setup:pyodide`
2. Validated the reported failure via `python -m debug --scenario flowchart-tweaked` to capture the arrow CURIE expansion error (`NotInKnownException`).
3. Reviewed meta builder architecture using `meta_builder/readme.md` to respect override regeneration expectations.
4. Implemented targeted updates in `legacy/overrides/curie_validator.py`:
   - Added `_looks_like_absolute_uri` helper to detect bare IRIs.
   - Normalised arrow identifiers by converting absolute IRIs to known CURIEs when a namespace match exists.
   - Allowed absolute identifiers to bypass `_ensure_known_curie` while still participating in downstream processing.
   - Ensured property tracking (object/datatype) uses the normalised identifier.
   - Enhanced `serialise_to_graph` with `_resolve_property_uri` so absolute properties are emitted as `URIRef` values when no CURIE mapping is available.
5. Regenerated generated assets using `python -m meta_builder --output legacy/draw_io_parser.py` and `python -m meta_builder --output drawio_meta.py` to apply the overrides.
6. Ran `python -m debug --scenario flowchart-tweaked` to confirm the scenario now succeeds and produces isomorphic pipeline/plugin graphs.
7. Executed the mandated test workflow:
   - `bun run fix`
   - `bun run check`
   - `bun run test:log:linux`
   - `bun run debug:all:log:linux`
   - `bun run test:pytest:all:log:linux`
   - `bun run test:bun:all:log:linux`
   - `bun run test:all:log:linux`
8. Verified graph behaviour programmatically to ensure literal targets for bare-IRI properties remain intact.
9. Documented results (this report) and prepared for changelog + PR messaging.

## Testing Evidence
- `python -m debug --scenario flowchart-tweaked` → passes with consistent turtle output.
- `bun run check` → lint and formatting checks succeeded after automatic fixes.
- `bun run test:log:linux` → Bun integration tests pass (30 pass / 11 skip / 0 fail).
- `bun run test:all:log:linux` → Aggregate Bun + pytest workflow succeeds (no failures).

## Additional Notes
- Added defensive logic only within overrides; generated parser and metadata files updated via meta builder CLI.
- No modifications were required for TypeScript sources.
- ChangeLog update pending alongside final commit/PR preparation.
