Milestone 6 (final) of the Configuration Engine sprint.
- docs/EDITOR.md: new "Configuration schema, form engine, and validation
architecture" section covering the field-schema registry, centralized
validators, live inline feedback, undo/redo, modified-field tracking, and
pre-publish preview added in M1-M5. Updated the facade signal list and
folder tour to include schema/.
- ADR-0002 (docs/context/adrs/): records the metadata-augmented-vs-fully-
schema-driven decision, why severity splits blocking/advisory, and the
accepted debt (partial [error] binding coverage, schema not yet driving
template labels).
- FACTS.jsonl (project-editor): decision fact pointing at the ADR.
Note: `barry-cache` is a phantom devDependency (no bin resolves, confirmed in
M1) - ADR/FACTS were authored by hand matching the existing schema/format
rather than via `npm run barry -- adr new` / `validate`.
Gate: tsc --noEmit, npm test (33/33), arch:check, build all green.
