Adds the durable architecture record epic #631 lacked: layer contract,
authority boundaries, the redaction boundary, /api/v1 versioning with a
compatibility rule for the existing unversioned MVP exports, a target page
map, per-child component ownership for all twenty children (#632-#651),
phase gates, and explicit forbidden paths.
Documentation only. No UI, API, or deployment change.
