Stage B of the three-stage backup-hardening plan (Stage A:
inline-DB-dump + fail-loud guard already landed). The file-backup
walker used to hard-code its subdirectory list inside
`getFilesToBackupInternal`, which is the same footgun that hid the
`business-docs` gap for ~6 months — a new feature drops artefacts
under STORAGE_PATH and the maintainer has to remember to edit the
walker.
Now driven by a `backup_paths` table:
- Migration 108 creates the table and seeds the 7 canonical
defaults (events/active, events/archived, thumbnails, previews,
heroes, uploads, business-docs). Seed data lives on the
migration as `DEFAULT_PATHS` so the boot self-heal can re-use it.
- `_backupPathsBoot.js` mirrors `_emailTemplateBoot.js`: on every
boot it diffs the canonical list against the current rows and
`INSERT ... ON CONFLICT DO NOTHING`s the missing ones. Keeps
admin edits intact, picks up new defaults shipped after the
install (Knex won't re-run migration 108). Wired into server.js
just before `startBackupService()`.
- Walker now calls `resolveBackupPaths(config)` which:
* reads `backup_paths WHERE include_in_default=true ORDER BY
display_order`
* falls back to a hard-coded `LEGACY_BACKUP_PATHS` if the
table is missing OR empty (defense in depth — never silently
scans nothing)
* gates each row by its `feature_flag` column (matches how
`backup_include_archived` already worked; data-driven now)
- Backward compatible: `getFilesToBackup(true|false)` still works
for legacy callers and the existing businessDocs test. New
callers should pass the full config object so feature gates
other than `backup_include_archived` evaluate correctly.
Tests:
- new: `backupService.configurableWalker.test.js` — 7 cases
covering canonical seed, toggling include_in_default, runtime
INSERT picked up without restart, feature_flag gating both on
and off, empty-table → LEGACY fallback, boolean backward compat
- all 15 backup-walker integration tests pass
(configurableWalker 7 + inlineDbDump 5 + businessDocs 3)
- frontend build clean
- 4 pre-existing integration failures (webhookDelivery, storage
backend, adminPhotos.reference, imageProcessor.storage) confirmed
unrelated via `git stash` baseline run
Stage C (CRM feature coverage audit + diagnostic UI) follows
in a separate commit.
