## What was done

Documentation coverage brought to 100% as part of the DDD restructuring effort (BDL-008).
Separate BDL number because it was a distinct deliverable within the restructuring.

### Deliverables
- **9 feature SPECs** — `SPEC.md` for every feature node in the architecture graph:
  - `cache`, `search`, `why` (Context Oracle domain)
  - `graph-diff`, `rule-engine`, `import-resolver` (Graph domain)
  - `doctor`, `reindex`, `watcher` (Infrastructure domain)
- **TUI service doc** — `docs/services/tui.md`
- **Architecture constraints updated** — multi-language support, configurable paths

### Result
- Doc coverage: 0% feature specs → 100% (20/20 nodes documented)
- All docs linked to graph nodes via `docs:` field in YAML
