## 1. OpenSpec Artifacts

- [x] 1.1 Create proposal, design, spec, and tasks artifacts for a documentation-only synchronization change.
- [x] 1.2 Validate the new change with `openspec validate sync-implemented-docs-and-comments --strict`.

## 2. Documentation Synchronization

- [x] 2.1 Update platform API route documentation to remove stale deferred/gap language for implemented metrics, config diff, file dispatch, log ingest/query, artifact chunks, browser artifact download, plugin bridge execution, and mediated AI invocation while preserving real future-work boundaries.
- [x] 2.2 Update AI provider, run artifact, frontend API, and plugin README documentation to match implemented behavior.
- [x] 2.3 Update stale handler Swagger comments for artifact and log stream metadata.

## 3. Verification

- [x] 3.1 Run focused stale-marker scans for the corrected files.
- [x] 3.2 Run `scripts/check-structure.sh`.
- [x] 3.3 Run `openspec validate sync-implemented-docs-and-comments --strict` after implementation.
