21 files defined their own local formatDate (with three different output
formats: date, datetime, datetime-seconds, and varying null fallbacks).
Replace them with a single shared helper at src/lib/format-date.ts that
takes a variant + optional fallback, preserving the exact previous output
per call site (verified identical string results).
Removes ~21 copies of the same logic. photos.tsx and media-grid.tsx keep
their epoch-ms based formatters since those are a different input shape.
Verified: tsc --noEmit clean, full test suite green (301/301).
Remove 19 unused source files (no importers anywhere in src/):
- src/actions/admin-permissions.ts, admin-radio.ts, admin-user-edit.ts,
admin-users.ts (functionality lives in @/actions/users and
@/actions/permissions)
- src/components/admin/confirm-action.tsx, page-header.tsx
- src/components/motion-elements.tsx
- src/lib/format-date.ts
- src/lib/catalog-categories/* (incl. re-export barrel)
- src/lib/foundation/{index,database,middleware,validation}.ts (errors/action
kept, still imported directly)
- src/lib/services/imager/{avatar-renderer,memory-cache}.ts
- src/lib/services/nitro-assets.ts
Update admin-operations-contract test to drop the two removed action-file
gates (their permission coverage already exists in users.ts/permissions.ts).
Add knip.json for repeatable dead-code audits.
Verified: tsc --noEmit clean, next build succeeds, full test suite green
(301/301).
