Conversation
…ves to storage Adds a Backups page under admin settings: download a complete content backup (all content including drafts and trash, schema, taxonomies, menus, widgets, media metadata, site settings — never users or secrets), plus optional daily automatic backups written to the site's storage bucket with configurable retention. Scheduled runs piggyback on the existing maintenance tick. New admin-only backups:manage permission. The public media route now denies keys under backups/. Ref: Discussion emdash-cms#142

…xposure caveat LocalStorage.list matches directory + filename prefix rather than flat keys, so include the emdash-backup- filename prefix in the list call. Docs now warn that publicly exposed buckets serve archives by URL.

This is a well-scoped, architecture-fitting backup feature. The implementation reuses the snapshot generator, adds a new admin-only backups:manage permission, protects archives from the public media route, validates storage keys before touching them, and wires scheduled runs into the existing maintenance tick. The tests cover export fidelity, secrets exclusion, archive-name validation, retention pruning, and route authorization. Overall approach is sound and the change is additive/minor as the changeset claims.
I didn't run tests/builds/lint, so I can't verify the reported green CI; I reviewed code and conventions statically. My concerns are about two AGENTS.md conventions in the new code:
-
Admin UI color tokens:
BackupSettings.tsxhand-rolls error/warning callouts with raw Tailwind colors anddark:prefixes (red-*,amber-*). AGENTS.md requires admin UI to use Kumo semantic tokens and explicitly forbidsdark:prefixes; the project's ownDialogErrorcomponent already shows the right pattern (bg-kumo-danger/10,text-kumo-danger). These callouts should be switched to Kumo status tokens. -
Error-code centralization: The backup code and routes introduce ad-hoc error strings like
BACKUP_SETTINGS_ERROR,BACKUP_CREATE_ERROR,BACKUP_LIST_ERROR,BACKUP_DELETE_ERROR,BACKUP_EXPORT_ERROR, andBACKUP_DOWNLOAD_ERRORinstead of adding them to the centralErrorCodeobject inpackages/core/src/api/errors.ts. The codebase'serrors.tsexplicitly says all handler/route error codes should be defined there; centralizing keepsmapErrorStatusand client-side error mapping consistent.
Both are fixable in small follow-up commits and don't change the public API shape.

[needs fixing] This error banner uses raw Tailwind colors (border-red-200, bg-red-50, text-red-800) and dark: prefixes for theming. AGENTS.md requires admin UI to use Kumo semantic tokens and explicitly forbids dark: prefixes (Kumo tokens use light-dark() internally). The project already has the correct pattern in DialogError.tsx: bg-kumo-danger/10 and text-kumo-danger.

Fixed in cddba1d — the error banner now reuses the existing DialogError component instead of a hand-rolled callout.

[needs fixing] This warning callout is hand-rolled with raw Tailwind amber/red colors and dark: variants. As above, AGENTS.md forbids raw Tailwind colors and dark: prefixes in admin components. Replace with Kumo status tokens (e.g. bg-kumo-warning/10, text-kumo-warning, border-kumo-warning/20) or use a Kumo-provided banner/callout component instead.

Fixed in cddba1d — switched to border-kumo-warning/50 bg-kumo-warning-tint text-kumo-warning (same tokens the WordPress-import warning callouts use), no raw Tailwind colors or dark: prefixes left.

[needs fixing] The backup code introduces ad-hoc error codes (BACKUP_SETTINGS_ERROR, BACKUP_LIST_ERROR, BACKUP_CREATE_ERROR, BACKUP_DELETE_ERROR) instead of adding them to the central ErrorCode enum in packages/core/src/api/errors.ts. errors.ts says "Routes and handlers should import error codes from this module instead of using ad-hoc strings." Adding them to ErrorCode keeps mapErrorStatus, logging, and client-side error mapping consistent.

Fixed in cddba1d — all backup codes (BACKUP_SETTINGS_READ_ERROR, BACKUP_SETTINGS_ERROR, BACKUP_EXPORT_ERROR, BACKUP_LIST_ERROR, BACKUP_CREATE_ERROR, BACKUP_DELETE_ERROR, BACKUP_DOWNLOAD_ERROR) are now registered in the central ErrorCode object, and the handler + all three route files reference ErrorCode.* instead of string literals.

[suggestion] This archive timestamp is formatted with the browser-default toLocaleString(). Since the admin locale is bound through Lingui, use the active Lingui locale (or a date formatter from @lingui/core) so the displayed date/time matches the user's chosen locale.

Fixed in cddba1d — timestamps now go through i18n.date(…, { dateStyle: "medium", timeStyle: "short" }) from the active Lingui context.
