## Context
- Task: Investigate rdfexport plugin test failures reported by `bun run test:log:linux`.
- Location: `src/main/webapp/plugins/rdfexport`.

## Findings
- `scripts/test_legacy.sh` invoked Python tooling (meta builder, pytest, baseline regeneration) without activating the project virtual environment. After the recent migration to `uv`, the required Python dependencies (e.g., `rdflib`) only exist inside `.venv`, so the harness failed with `ModuleNotFoundError: No module named 'rdflib'`.
- `legacy/tests/test_patched_parser.py::test_generated_metadata_fixtures_round_trip` began failing because new fixtures (e.g., `General_Authority_bleep_mock.drawio`) already ship with root `<UserObject>` metadata. The metadata patcher now rejects re-injecting metadata, causing subprocess failures.

## Changes
1. Updated `scripts/test_legacy.sh` to:
   - behave as a strict bash script (`set -euo pipefail`),
   - resolve the project root, activate `.venv/bin/activate` when present, and
   - run the legacy regeneration + pytest suite from the expected working directory.
   This guarantees Python tooling sees the synced dependencies installed by `bun run setup:uv`.
2. Added `_fixture_contains_metadata` helper in `legacy/tests/test_patched_parser.py` and filtered fixtures that already include metadata, so the round-trip regression covers only plain diagrams. This reflects the repository’s updated fixtures and avoids double-patching failures.
3. Refreshed `tests/demo_logs/test.log` via `bun run test:log:linux` to capture the successful run.
4. Recorded the fix in `CHANGELOG.md` and logged this report under `docs/aicode/` per contributor guidelines.

## Validation
- `bun run test:log:linux`
- `CI=1 bun run check`
