 - [Phase 14.2]: The surf uploads route owns storage.uploads.public_path_prefix: BuildRouter fails when a plugin route sits at or under it
 - [Phase 14.2]: check-phase14.2.sh --contracts blocks on the phase's own contract test and only reports the whole pnpm test:contracts suite (missing-catalog.test.mjs predates the phase)
 - [Phase 14.2]: check-phase14.2.sh leaves TMPDIR to the caller: a TMPDIR inside a go.work tree makes internal/build scaffold tests edit that go.work
+- [Phase 17]: 17-01: menu item type registry is modules/signpost (party activates it before Boot); host URL overrides at menu_items.patterns (YAML only); list types use PatternFrom (one level) so a record type's host override reaches list children
+- [Phase 17]: 17-01: framework sanitizer modules/seaglass on bluemonday v1.0.27 (Journal policy without Blog Editor rules, plus tel:); D-10 Journal clause dropped, category content stays blogeditor
+- [Phase 17]: 17-01: dependent dropdown options for a repeater row are addressed as {field}=repeater.nested; sibling values reach DependentOptions as strings (nil when empty) on the route and the save recheck
+- [Phase 17]: 17-01: reorder saves write parent and sort columns via UpdateColumns (no model hooks); the partition is a belongsTo relation field of the form; stale sets answer 409 reorder_stale
