The step confirmed one key, the active application key. A restore needs more: off-host copies are sealed under BACKUP_ENCRYPTION_KEY, a copy written before a rotation needs the retired application key it was written under, and every session, token and share link hangs off API_TOKEN_HMAC_KEY. An operator could do everything the step asked and still be unable to read a single backup. The recovery kit lists every key a restore of this server needs, by id and fingerprint, never key material: - each id in ENCRYPTION_KEYS, plus any retired id a stored copy (innerKeyIds) or an off-host object inside the bucket's retention (OffhostBackupKeyUse) still lists, also once the server dropped it; - BACKUP_ENCRYPTION_KEY and each BACKUP_ENCRYPTION_PREVIOUS_KEYS entry, named by the id their objects record; - API_TOKEN_HMAC_KEY. Confirming records the set the admin was shown and refuses a stale one with 409 recovery.kit.stale. The kit is due again as soon as a key it lists is not in that set (a rotation, a new backup key, a re-keyed install); a key that merely drops out does not make it due. "Check my copy" now checks any key in the kit. Migration 0487 carries a confirmation given under the old step forward as a kit holding that key, so that part stays confirmed, and drops the four app_settings columns. It also creates the two tables the readiness evaluation uses (restore_drill_outcomes, recovery_readiness_notices). The routes move to /api/admin/recovery-kit; the reader of the keys the backups still need moves out of the encryption status route into src/lib/recovery/backup-key-needs.ts so the kit and the status view share one definition.
src/components/
React components. The UI primitives are shadcn/ui (new-york style, zinc base) over Radix + Tailwind 4 + Lucide; everything above the primitives is feature-grouped by surface. Components are server components unless they need a hook, state, or browser API, in which case they open with "use client". Charts use Recharts 3 — replacing the chart library requires explicit approval.
Primitives and shell
ui/— shadcn/ui primitives (button, dialog, sheet, table, …). Generated by the shadcn CLI; keep edits minimal and on-style.layout/— the app shell: sidebar, topbar, bottom nav.providers.tsx,version-poller.tsx— top-level context providers and the self-healing stale-shell poller.i18n/— translation context + locale switcher.
Feature groups
insights/— insight status, assessment cards, Coach surface, advisor cards (the largest group).medications/— medication cards, the schedule wizard, intake timeline, detail history.settings/— the section components behind each settings page.measurements/,mood/,dashboard/— entry forms, lists, dashboard tiles.charts/— Recharts wrappers.monitoring/— Umami / GlitchTip client bootstrap.gamification/,targets/,comparison/,doctor-report/,clinician/,onboarding/,admin/— the remaining per-surface groups.
Conventions
Kebab-case filenames; React component exports stay PascalCase regardless. (A handful of PascalCase-filename outliers under medications/ + onboarding/ are pre-existing drift, noted in ../../CLAUDE.md.) Every t() call needs a matching key in messages/en.json — guarded by i18n-call-site-coverage.test.ts. Data reads go through TanStack Query with keys from @/lib/query-keys and unwrap (await res.json()).data. Tests live in __tests__/.
