# Task 4 – Phase 1 Completion Report (Pyodide Integration)

## Overview
- Implemented an asynchronous Pyodide-powered mock pipeline for the RDF export black box.
- Added structured logging utilities to unify [PIPELINE], [PYODIDE], and [BLACKBOX] debug output.
- Ensured the mock Python `process` function returns `mock:`-prefixed payloads and is invoked from TypeScript via Pyodide.
- Updated DrawIO action wiring to await the Pyodide pipeline, propagate errors, and emit lifecycle logs.
- Extended Bun test suite to exercise the asynchronous pipeline, Pyodide debug helper, and export flow.
- Installed the Node-compatible Pyodide runtime, plus Python dependencies via `uv`, to satisfy Phase 1 testing requirements.

## Files Updated / Added
- `src/main/webapp/plugins/rdfexport/src/logging.ts` (new) – central logging helpers for consistent prefixes.
- `src/main/webapp/plugins/rdfexport/src/pyodideRuntime.ts` (new) – lazy Pyodide bootstrap, mock invocation, debug evaluation.
- `src/main/webapp/plugins/rdfexport/src/mockBlackBox.ts` – now async with Pyodide integration and error handling.
- `src/main/webapp/plugins/rdfexport/src/rdfexport.ts` – export action awaits the Pyodide pipeline and logs progress.
- `src/main/webapp/plugins/rdfexport/tests/rdfexport.test.ts` – adapted to async APIs, added Pyodide debug coverage, extended timeouts.
- `src/main/webapp/plugins/rdfexport/package.json` & `bun.lock` – declared `pyodide` dependency.
- `docs/aicode/gpt-5-codex-report-20251009T123258Z.md` – this report.
- `AGENTS.md` – Phase 1 status marked complete.

## Testing Summary
Executed from `src/main/webapp/plugins/rdfexport` after syncing Python deps with `bun run uv` and activating the created virtual environment:
- `bun run test`
  - Regenerates legacy baselines (expected warnings for fixtures with undeclared properties).
  - Runs Python pytest suite via the local venv.
  - Executes Bun test suite, exercising the Pyodide-powered mock pipeline.

All suites completed successfully after accommodating Pyodide initialization time.

## Follow-up Notes
- Phase 2 remains outstanding and will build on this Pyodide runtime by porting actual parser/dataframe routines.
- The new `debugPyodide` helper can be extended in future phases to drive REPL tooling inside the UI if desired.
- The DrawIO action now returns a promise; existing UI callers ignore the return value, but we should document this for maintainers.

## Maintenance Log – 2025-02-15
- Installed plugin dependencies, executed `bun run lint`, and resolved style diagnostics introduced after Phase 1.
- Ran `bun run format` to align TypeScript sources and tests with the project Prettier configuration.
- Confirmed that all resulting changes were limited to automated formatting within the Pyodide runtime, plugin entrypoint, and associated Bun tests.
