+/**
+ * Integration test for GET /api/admin/system-health/backup-coverage.
+ *
+ * Pins the Stage C diagnostic that tells admins what the next
+ * "Run Backup Now" will include, skip, or silently miss.
+ *
+ * Test surface:
+ *   1. Empty / fresh install → default seed (7 paths), inline mode,
+ *      no DB dump on file yet, no drift
+ *   2. Toggle `include_in_default=false` → coverage flips to
+ *      'skipped-by-toggle'
+ *   3. Feature_flag gating reflects the actual app_settings value
+ *      (events/archived ⇄ backup_include_archived)
+ *   4. Drift detection: a top-level subdir on disk with no
+ *      `backup_paths` row is flagged in `unconfiguredOnDisk`
+ *   5. Allow-list: `backups/` and `tmp/` are never flagged as drift
+ *   6. Scheduled-only mode + recent dump → `database.ok = true`
+ *   7. Scheduled-only mode + stale (>26h) dump → `database.ok = false`
+ *      and `lastDumpStale = true`
+ *
+ * Same auth/permission pass-through strategy as
+ * adminBackupIntegrity.test.js — we exercise the route's logic,
+ * not the auth middleware.

+/**
+ * Pins the fix for the PR #596 review blocker.
+ *
+ * **The bug**
+ *
+ *   `preservedMeta` was declared with `let` INSIDE the PostgreSQL
+ *   `else` branch of `performDatabaseRestore`, then read AFTER the
+ *   `else` block closed at the shared replay site (~L1030). On every
+ *   real PG restore:
+ *
+ *     ReferenceError: preservedMeta is not defined
+ *
+ *   would fire — psql had already completed the data restore, but
+ *   the operator-meta replay never ran, the trigger file was left
+ *   in place by `_installFromBackupBoot.js` because the restore
+ *   "failed", and `combined.log` got a loud FAILED line even though
+ *   the data was back. Caught on PR #596 review by the maintainer.
+ *
+ * **Why CI missed it**
+ *
+ *   The integration tests around `performFullRestore` only exercise
+ *   the SQLite branch via `this.dbType === 'sqlite'`. The PG branch
+ *   (~L827-984) requires a real PG connection + real `psql` binary,
+ *   neither of which are in the test environment. So the scope leak
+ *   sat untested until the maintainer ran a real DR cycle.
+ *
+ * **What this test does**
+ *
+ *   Reads the source of `restoreService.js` and asserts the scope
+ *   contract: the `preservedMeta` declaration sits ABOVE the
+ *   SQLite/PG branch split, so the replay block at the bottom of the
+ *   try{} can read it on either branch.
+ *
+ *   Source-inspection is uglier than a runtime test but it has two
+ *   advantages here: (a) it doesn't require a real PG cluster + psql
+ *   binary in CI, (b) it pins the EXACT contract — "the declaration
+ *   must be visible to the replay block" — which is the property
+ *   that broke, more directly than a runtime test would.
+ *
+ *   The follow-up "real-PG integration test in CI" (separate task)
+ *   would replace this with an end-to-end exercise, at which point
+ *   this can be deleted.

+/**
+ * Migration 109 — config-driven backup walker.
+ *
+ * (Originally numbered 108 on bugfix/crm-backup. Renumbered to 109
+ * before merge because upstream/beta independently shipped
+ * 108_seed_sl_email_template_translations.js. The createTable is
+ * idempotent via `hasTable` guard and the seed uses
+ * `onConflict('path').ignore()`, so beta installs that ran the
+ * 108-named version of this file get a harmless no-op when 109
+ * runs against the already-seeded table.)
+ *
+ * Stage B of the three-stage backup-hardening plan. The file-backup
+ * walker (`getFilesToBackupInternal` in backupService.js) historically
+ * hard-coded its list of subdirectories: events/active, events/archived,
+ * thumbnails, previews, heroes, uploads, business-docs.
+ *
+ * That list is a footgun every time a new feature lands that drops
+ * artefacts under STORAGE_PATH/<something>/ — the maintainer has to
+ * remember to edit the walker, and there's no schema-level record of
+ * what *should* be backed up. The CRM rollout missed `business-docs`
+ * for ~6 months (#XXX) for exactly this reason.
+ *
+ * This migration introduces a `backup_paths` table that the walker
+ * reads at runtime. New features add a row; the walker picks them up
+ * automatically. The `feature_flag` column gates scans behind an
+ * existing app_settings boolean (e.g. `backup_include_archived`),
+ * mirroring how the previous `includeArchived` parameter worked.
+ *
+ * Columns:
+ *   - path                : relative to STORAGE_PATH, unique
+ *   - include_in_default  : on/off without deleting the row (so
+ *                           audit trail of "we used to back this up"
+ *                           is preserved)
+ *   - feature_flag        : nullable; when set, walker checks the
+ *                           same-named app_settings boolean before
+ *                           scanning. Matches the existing pattern
+ *                           used by `backup_include_archived`.
+ *   - display_order       : controls admin-UI listing order
+ *   - description         : human-readable purpose, shown in admin UI
+ *
+ * Defense-in-depth: the walker also keeps a hard-coded LEGACY_DEFAULTS
+ * fallback so that if this table is somehow empty (failed migration on
+ * an existing install, manual truncation), backups still cover the
+ * historical set instead of silently shipping nothing. The boot-time
+ * self-heal in `_backupPathsBoot.js` re-seeds missing default rows on
+ * every startup so newly-added defaults reach already-deployed
+ * installs without a follow-up migration.
+ *
+ * Idempotent: skips the createTable if it already exists, and the
+ * seed uses `onConflict('path').ignore()` so re-runs don't duplicate.

+ * Discover restorable backups by walking the configured destination
+ * directory + harvesting the backup_runs table.
+ *
+ * **Why we recurse the disk first, DB second**
+ *
+ * The disk is the source of truth for restore. After a disaster
+ * (`docker compose down -v`, drive corruption, fresh install) the
+ * `backup_runs` table is empty — but the manifest JSONs are exactly
+ * what's left on disk for an admin to recover from. A wizard that
+ * only reads the DB shows "No backups found" precisely when the
+ * admin needs it most. So we walk first, dedupe-by-manifestId
+ * against any surviving DB rows, and present a unified list.
+ *
+ * Discovery rules:
+ *   - Walks `backup_destination_path` AND `backup_manifest_path` if
+ *     they're distinct (manifests can live in a sibling directory).
+ *   - Recurses up to 3 levels deep — enough to find
+ *     `<root>/manifests/backup-manifest-<id>.json` (the default
+ *     layout) without scanning the entire photo tree.
+ *   - Matches manifest files by glob: `backup-manifest-*.json`,
+ *     `backup-manifest-*.yaml`, and the legacy bare `manifest.json`.
+ *   - Parses each manifest to extract real metadata (timestamp,
+ *     size, file count, source type) instead of showing the admin
+ *     a list of opaque filenames.
+ *
+ * Returns: array of `{ type, name, path, manifestId, size,
+ * filesCount, completed, source: 'disk' | 'db' }`.

+/**
+ * Install-from-backup boot hook.
+ *
+ * **The problem this closes**
+ *
+ * Without this hook, recovering a picpeak install from a backup is a
+ * six-step process:
+ *   1. Stand up the compose stack with empty volumes
+ *   2. Wait for boot → land on the onboarding wizard
+ *   3. Create a throwaway fresh-install admin
+ *   4. Navigate to Backup → Restore
+ *   5. Walk through the wizard with Force Restore ticked
+ *   6. Log out, log back in with original (pre-disaster) credentials
+ *
+ * With this hook, admins skip steps 2-6. They place their backup
+ * artefacts in the existing bind-mounted /backup directory, drop a
+ * trigger file alongside, and the next container start runs the
+ * restore BEFORE creating the throwaway onboarding admin. Server
+ * comes up populated, original login works first try.
+ *
+ * **The trigger file convention (chosen for zero compose-file changes)**
+ *
+ * Drop a file named `RESTORE_ON_INSTALL` (no extension, or .txt) into
+ * the root of the `/backup` mount. Two payload variants:
+ *
+ *   1. EMPTY file (or pure whitespace) — auto-pick the newest
+ *      `backup-manifest-*.json` from `/backup/manifests/`. Useful when
+ *      the admin doesn't know or care which one is most recent.
+ *
+ *   2. NON-EMPTY file containing a relative or absolute path to a
+ *      specific manifest. Trimmed; first line wins. Useful when the
+ *      admin wants a specific older backup.
+ *
+ * After a successful restore the trigger file is DELETED so the next
+ * boot doesn't re-trigger. On failure the file is preserved + the
+ * error is logged, so the admin can fix the input and retry by just
+ * restarting the container.
+ *
+ * **Safety**
+ *
+ * Three layers gate this against accidental data loss:
+ *   1. Trigger file must exist (intentional admin action, not auto-magic)
+ *   2. DB must be empty — admin_users.count = 0 AND events.count = 0.
+ *      If either is non-zero, the hook refuses to run.
+ *   3. The Stage A restore path (with all of tonight's fixes) handles
+ *      the actual swap atomically. If anything fails, the rollback
+ *      runs and the install stays in fresh-install state.
+ *
+ * Override: `INSTALL_FROM_BACKUP_FORCE=true` skips the empty-DB check
+ * for the "I know what I'm doing" edge case (e.g. dev environment
+ * rebuilds where there's leftover data that's safe to clobber).

+/**
+ * Boot-time self-heal for restore-meta settings.
+ *
+ * **Why this exists**
+ *
+ * `restore_allow_force` gates whether the Restore wizard accepts a
+ * `force: true` payload. The flag exists to add admin friction
+ * before letting a restore override safety warnings (e.g. "1 active
+ * admin user — restoring would clobber the current install").
+ *
+ * In practice the friction lands at the worst possible moment: a
+ * fresh install (no app_settings row yet OR `restore_allow_force =
+ * false` by default) hits the wall on its very FIRST restore. The
+ * admin is mid disaster-recovery, panicked, and gets:
+ *
+ *   "Force restore is not allowed by system settings"
+ *
+ * They then have to hand-craft SQL like
+ *
+ *   INSERT INTO app_settings (setting_key, setting_value, ...)
+ *   VALUES ('restore_allow_force', 'true', 'restore', NOW())
+ *   ON CONFLICT ... SET setting_value = 'true';
+ *
+ * before they can recover their data. This isn't security — the
+ * admin who could run that SQL could also flip the setting via the
+ * UI. It's just a sharp edge that bites every new install once.
+ *
+ * Cure: seed the default ON at boot via `INSERT ... ON CONFLICT
+ * DO NOTHING`. New installs get force-allowed out of the box.
+ * Existing installs that have explicitly set the row (true OR
+ * false) are NOT overwritten — admin policy wins. Same pattern
+ * `_backupPathsBoot.js` uses for the canonical backup_paths rows.
+ *
+ * **Default-ON rationale (matches Stage A's principle)**
+ *
+ * Stage A defaulted inline DB dumps to ON because the cost of
+ * forgetting was data loss. By the same logic, `restore_allow_force`
+ * defaults ON because the cost of forgetting is being unable to
+ * recover from a disaster. Audit logging captures every forced
+ * restore so the accountability story stays intact.
+ *
+ * If/when the broader "exclude restore-meta settings from being
+ * overwritten by restore" follow-up lands (the second half of this
+ * chicken-and-egg), this self-heal becomes the safety net for
+ * fresh installs only — existing installs by that point have the

+ * Stage A (inline DB dump + fail-loud) and Stage B (config-driven
+ * walker via `backup_paths`) close the data-loss footgun, but they

+ *
+ * This service answers two questions:
+ *
+ *   1. For every row in `backup_paths`, what will the next backup
+ *      do with it? (scan / skip-via-feature-flag / skip-via-toggle /
+ *      missing-on-disk)
+ *   2. What subdirectories EXIST under STORAGE_PATH but have NO row
+ *      in `backup_paths` — i.e. drift the admin should know about
+ *      before they lose data on a restore?
+ *
+ * Plus a top-level database-dump status block: are we configured
+ * for inline dump (default), or relying on the scheduled dump?
+ * When was the last successful dump? Is it stale?
+ *
+ * **What this service does NOT do**
+ *
+ *   - Does not run the backup
+ *   - Does not write anything (no DB mutations, no fs touches)
+ *   - Does not auto-recover drift (it's a diagnostic — admins decide
+ *     whether to add a `backup_paths` row, delete the orphan dir, etc.)
+ *   - Does not walk file contents — only top-level directory entries
+ *     under STORAGE_PATH are inspected (cheap; no recursion through

+/**
+ * Backup-integrity verifier — walks every CRM document-artefact path
+ * column and confirms (a) the file exists on disk, (b) when a SHA-256
+ * is stored, the file's actual bytes hash to the stored value.
+ *
+ * **Why this is a separate service**
+ *
+ * The audit trail captured at issue / sign time (signed_customer_ip,
+ * signed_by_customer_at, signed_pdf_sha256, signed_*_signature_path,
+ * issue_date, etc.) is worth exactly nothing on its own — what makes
+ * it legally meaningful is being able to produce the document the
+ * audit trail refers to. A backup that captures the DB but skips
+ * `storage/business-docs/` (the bug fixed in this same PR) leaves
+ * every `*_path` column a broken FK and every `*_sha256` column with
+ * nothing to verify against. This service is the diagnostic for
+ * exactly that drift — runs on demand, surfaces missing files +
+ * hash mismatches without making any changes.
+ *
+ * **Verification modes**
+ *
+ *   - existence — file at `*_path` must exist on disk
+ *   - sha256    — file at `*_path` must exist AND its sha256 must
+ *                 equal `*_sha256` column (when that column is set)
+ *
+ * Per-table coverage (lines reference migrations/core/107_crm_consolidated.js):
+ *
+ *   quotes.pdf_path                            line 844   (existence)
+ *   contracts.pdf_path                         line 1245  (existence + sha256 via contracts.pdf_sha256)
+ *   contracts.signed_pdf_path                  line 1246  (existence + sha256 via contracts.signed_pdf_sha256)
+ *   contracts.signed_customer_signature_path   line 1269  (existence — drawn signatures, no hash column)
+ *   contracts.signed_admin_signature_path      line 1273  (existence — admin counter-signature drawing)
+ *   invoices.pdf_path                          line 1026  (existence)
+ *   invoices.imported_pdf_path                 line 1020  (existence — admin-uploaded scans)
+ *
+ * Wet uploads (`contracts.signed_pdf_is_wet_upload = true`) DO have a
+ * `signed_pdf_sha256` computed at upload time (contractService.js
+ * upload route), so they're hash-verified the same as system-rendered
+ * contracts — no special case here.
+ *
+ * **What this service does NOT do**
+ *
+ *   - Does not write anything (no DB mutations, no fs touches)
+ *   - Does not fail the request when a mismatch is found — the
+ *     report shape carries the data, the caller decides what to do
+ *   - Does not auto-trigger after restore (D2 decision: surface a
+ *     CTA on the restore-completed screen instead)
+ *   - Does not run on a schedule (D1 decision: on-demand v1; revisit
+ *     once we have runtime data on large installs)

+      // restart" — but that left the running process serving a

+      // Not acceptable per the "backup must restore completely even

+      // is untouched). Idempotent — migrations already applied are
+      // tracked in the restored `migrations` table and get skipped.

+
+# Backup & Restore
+
+picpeak's backup system captures your entire install — database, photos, CRM documents, gallery archives, and configuration — to a destination of your choice. Recovery happens through one of two paths depending on how badly things went wrong:
+
+- **The install is alive** → use the **Restore wizard** in the admin UI to roll back to a chosen backup.
+- **The install is gone** (host migration, `docker compose down -v`, drive replacement) → use the **install-from-backup** trigger file convention to rebuild in one boot, with no onboarding wizard and no temporary admin step.
+
+This guide covers both.
+

+
+## What gets backed up
+
+Every "Run Backup Now" (manual or scheduled) produces:
+
+1. **A database dump** captured inline at the start of the run. Always included by default. picpeak refuses to ship a backup without a database dump unless the operator has explicitly opted out via the `backup_database_inline_dump` setting — see [Inline DB dump](#inline-db-dump) below.
+
+2. **Files from a configurable list of paths**, declared in the `backup_paths` table:
+   | Path | Default | Notes |
+   | --- | --- | --- |
+   | `events/active` | ✓ | Live gallery photo originals |
+   | `events/archived` | gated by `backup_include_archived` | Long-term archive |
+   | `thumbnails` | ✓ | Generated thumbnails |
+   | `previews` | ✓ | Lightbox preview tier |
+   | `heroes` | ✓ | Gallery hero images |
+   | `uploads` | ✓ | Wet-signature contracts, imported invoices, etc. |
+   | `business-docs` | ✓ | CRM PDFs, signature artefacts, imported historical invoices |
+
+   Admins can add or remove rows from `backup_paths` to teach the walker about new feature directories — see [Custom backup paths](#custom-backup-paths).
+
+3. **A manifest JSON** describing the run, written to `<destination>/manifests/backup-manifest-<id>.json`. The manifest carries the database dump path, the file inventory, checksums, and per-path counters.
+
+## Destinations
+
+picpeak supports three destination types, configured via **Backup → Configuration**:
+
+- **Local** — files copied to a directory on the same host (default: `/backup` inside the container, which is typically a bind mount).
+- **S3 / MinIO** — files uploaded via the S3 API. Supports custom endpoints (for MinIO, Backblaze B2, Wasabi, etc.).
+- **rsync** — synchronised to a remote host over SSH.
+
+Direct download from the admin UI is supported for local destinations; S3 backups can be retrieved via pre-signed URLs.
+
+## Inline DB dump
+
+Every "Run Backup Now" runs `pg_dump` (or `sqlite3 .backup`) inline before walking files. This guarantees the manifest's `database.backup_file` is always a fresh capture, never a stale reference to a previously-scheduled dump that may not exist.
+
+If the inline dump fails (disk full, pg_dump crash, permission error), the run aborts and writes the error to `backup_runs.error_message`. The UI surfaces this as a failed run — no more silent files-only manifests.
+
+**To opt out** (e.g. if you have a separately-orchestrated DB backup that you trust more):
+
+```sql
+INSERT INTO app_settings (setting_key, setting_value, setting_type, updated_at)
+VALUES ('backup_database_inline_dump', 'false', 'backup', NOW())
+ON CONFLICT (setting_key) DO UPDATE
+  SET setting_value = 'false', updated_at = NOW();
+```
+
+With inline-dump opted out, picpeak's fail-loud guard still applies: a file backup with no recent DB dump on file (within 26 hours) will fail rather than ship a files-only manifest.
+
+## Custom backup paths
+
+To add a new directory to the backup walker (e.g. you've shipped a feature that drops artefacts under `storage/my-feature/`):
+
+```sql
+INSERT INTO backup_paths (path, include_in_default, display_order, description, created_at, updated_at)
+VALUES ('my-feature', true, 100, 'My new feature artefacts', NOW(), NOW());
+```
+
+Next "Run Backup Now" picks it up — no restart, no migration. Set `include_in_default = false` to temporarily disable a path without dropping the row.
+
+The `feature_flag` column gates a path behind an app_settings boolean (matches how `events/archived` is gated by `backup_include_archived`). Useful when a backup path corresponds to an optional feature.
+
+## The Coverage tab
+
+**Backup → Coverage** answers "what will the next backup actually include?" without having to run it:
+
+- **Database** — inline-dump mode + last dump timestamp + staleness check
+- **Configured paths** — one row per `backup_paths` entry with its current coverage status (`will-scan` / `skipped-by-toggle` / `skipped-by-feature-flag` / `missing-on-disk`)
+- **Drift detection** — flags top-level directories under `STORAGE_PATH` that exist on disk but have NO matching `backup_paths` row. This is the canary for "a feature shipped without a matching backup row" — the most common cause of silent data loss in pre-2026-05 picpeak.
+
+The Coverage tab auto-fetches on open. If everything is green, your next backup will capture what you'd expect.
+
+## The Integrity tab
+
+**Backup → Integrity** verifies that every `*_path` column on quotes / contracts / invoices / signatures actually resolves to a file on disk, AND that files with a stored `*_sha256` still hash to the same value. Read-only, on-demand. Useful for:
+
+- Post-restore validation
+- Detecting bit-rot
+- Auditing legal-evidence artefacts before a tax review or dispute
+
+## Restoring on a live install
+
+Use this when picpeak is running and you want to roll back to a specific backup point — e.g. recovering accidentally-deleted records, reverting a bad migration, or testing a restore drill.
+
+**Backup → Restore** walks you through:
+
+1. **Source** — Local, S3, or rsync
+2. **Choose Backup** — manifests discovered from disk (works after a fresh install where `backup_runs` is empty) or from the database history
+3. **Restore Options** — Full / Database only / Files only / Selective + Force + Skip Pre-Restore
+4. **Review** — surfaces validation warnings before you commit
+5. **Restore Progress** — real-time stream of the actual steps
+
+Failures during restore trigger an automatic rollback from the pre-restore safety snapshot. The destination ends up either as the restored state OR as the original pre-restore state — never as a half-clobbered mix.
+
+### Restoring an older backup on a newer image
+
+picpeak's restore path is forward-compatible: a backup taken on an older version restores cleanly onto a newer image without any manual schema work. After loading the dump, the restore service runs the same `npm run migrate:safe` script that `wait-for-db.sh` uses on every container boot. Any migrations that have been added between the backup's snapshot and the current image are applied inline, against the freshly-restored DB, before the restore is reported as complete.
+
+Net effect: even if `bugfix/cool-new-feature` shipped a migration that adds a `widgets` table and your backup predates that branch, after restore your install has the `widgets` table (empty), the right indexes, and any seed rows the migration emits. No "you'll need to restart the container once" footnote.
+
+The same applies to the install-from-backup trigger — migrations land inside the restore boundary, so the moment the server prints `Server running on port 3000`, the schema matches the running image. Log in and use the install immediately.
+
+## Disaster recovery (install from a backup)
+
+For full DR after `docker compose down -v`, host migration, drive replacement, or moving an install between hosts. picpeak detects a trigger file on first boot and runs the restore before the admin UI surfaces. You open the browser, log in with your original credentials, and the install is fully populated.
+
+### Prerequisites
+
+- Your install's backup files must already be present in the `/backup` mount. They survive `docker compose down -v` because `/backup` is a bind mount, not a Docker-managed volume.
+- The image must include the install-from-backup feature (shipped 2026-05-31 on `beta`; available in `main` after the next stable release).
+- The backup must contain a database dump. The wizard cannot reconstruct your CRM data, customers, quotes, invoices, or admin users from a files-only backup. Confirm by inspecting any `backup-manifest-*.json` and checking that `database.backup_file` is non-null.
+
+### How the trigger works
+
+On every container start, picpeak's boot sequence checks for a trigger file in the root of the `/backup` mount. If found AND the destination database is empty, the restore runs automatically. After a successful restore the trigger file is deleted so the next boot doesn't redo the work. On failure the trigger file is preserved — fix the input and restart the container to retry.
+
+The trigger file is named **`RESTORE_ON_INSTALL`** (no extension) or **`RESTORE_ON_INSTALL.txt`** — either is accepted.
+
+### Two trigger flavors
+
+#### Auto-pick the newest backup
+
+Create an empty trigger file:
+
+```sh
+touch /path/to/backup/RESTORE_ON_INSTALL
+```
+
+The boot hook will scan `/backup/manifests/` for files matching `backup-manifest-*.json` (or `.yaml`) and pick the one with the most recent modification time. Best for the common DR case where you simply want the latest snapshot.
+
+#### Use a specific backup
+
+Write the path of the manifest you want — either relative to the `/backup` mount root or an absolute path — into the trigger file:
+
+```sh
+# Relative path (recommended)
+echo "manifests/backup-manifest-backup-20260530-190617-e9be97b3.json" \
+  > /path/to/backup/RESTORE_ON_INSTALL
+
+# Or absolute path inside the container
+echo "/backup/manifests/backup-manifest-backup-20260530-190617-e9be97b3.json" \
+  > /path/to/backup/RESTORE_ON_INSTALL
+```
+
+Use this when you need to restore an older backup (e.g. rolling back a data corruption that happened after the most recent backup ran).
+
+### Full DR walkthrough
+
+```sh
+# 1. Snapshot the backup outside the compose directory (belt + suspenders).
+#    This is a docker-compose-down-v-proof copy in case anything goes wrong.
+SNAPSHOT=~/picpeak-snapshots/$(date +%Y%m%d-%H%M%S)
+mkdir -p "$SNAPSHOT" && cp -av /path/to/picpeak/backup/. "$SNAPSHOT/"
+
+# 2. Verify the backup is restorable. database.backup_file must be non-null.
+LATEST=$(ls -t /path/to/picpeak/backup/manifests/*.json | head -1)
+docker compose exec backend cat "/backup/manifests/$(basename $LATEST)" \
+  | python3 -c "import json,sys; m=json.load(sys.stdin); \
+      print('DB included:', bool(m.get('database',{}).get('backup_file')))"
+
+# 3. Drop the trigger file. Two variants — pick one:

+
+# 4. Boot.
+docker compose down -v
+docker compose up -d
+docker compose logs -f backend --tail=100
+```
+
+When the boot log shows `Install-from-backup: restore completed successfully` followed by `Server running on port 3000`, the install is ready. Open the admin UI and log in with your original (pre-disaster) credentials.
+
+### Safety gates
+
+Three layers prevent accidental data loss:
+
+1. **The trigger file must exist.** No auto-magic — an admin explicitly drops the file to signal intent.
+
+2. **The destination database must be empty.** If the database contains any events, the install-from-backup hook refuses to run. The fresh-install default admin (auto-created by migration 001) is treated as throwaway and replaced by the backup's admin row, so a single admin user does not block the restore.
+
+3. **Failed restores roll back to the pre-restore state.** If anything fails after the DROP DATABASE step, picpeak's automatic rollback restores the destination from the pre-restore safety backup it took before starting.
+
+#### Override for advanced cases
+
+If you have a populated install you intentionally want to clobber (dev rebuilds, staging refresh, etc.):
+
+```yaml
+# In docker-compose.yml
+backend:
+  environment:
+    - INSTALL_FROM_BACKUP_FORCE=true
+```
+
+Or via the CLI:
+
+```sh
+INSTALL_FROM_BACKUP_FORCE=true docker compose up -d backend
+```
+
+With this set, gate #2 is skipped and the restore proceeds even with existing data. Gates #1 (trigger file presence) and #3 (rollback on failure) still apply.
+
+### Verifying DR success
+
+After the boot log shows `Install-from-backup: restore completed successfully`:
+
+```sh
+# Trigger should be gone (deleted on successful restore)
+ls /path/to/picpeak/backup/RESTORE_ON_INSTALL 2>/dev/null \
+  || echo "Trigger cleaned up — restore succeeded."
+
+# Inspect the restore_runs row
+docker compose exec -T postgres psql -U picpeak -d picpeak_prod -c \
+  "SELECT id, status, was_successful, was_rollback_attempted FROM restore_runs ORDER BY id DESC LIMIT 1;"
+
+# Confirm data is back
+docker compose exec -T postgres psql -U picpeak -d picpeak_prod -c "
+  SELECT 'admin' AS t, COUNT(*) FROM admin_users
+  UNION ALL SELECT 'events',       COUNT(*) FROM events
+  UNION ALL SELECT 'invoices',     COUNT(*) FROM invoices
+  UNION ALL SELECT 'app_settings', COUNT(*) FROM app_settings;"
+```
+
+Then open the admin login and use your **original** pre-disaster credentials.
+
+## Backup History detail
+
+Each row in **Backup → Backup History** expands to show:
+
+- **Database** — whether the dump was included
+- **Per-path file counts** — one row per `backup_paths` entry that contributed files, with count + total size. e.g.:
+  ```
+  events/active      142 (3.2 GB)
+  business-docs       17 (4.5 MB)
+  thumbnails         142 (12.4 MB)
+  ```
+- **Total files** + total bytes
+- Error message if the run failed
+
+This breakdown reflects Stage B's data-driven walker, so admins can see at a glance which paths contributed how much.
+
+## Settings reference
+
+Backup-related settings live in `app_settings` with `setting_type = 'backup'` or `setting_type = 'restore'`:
+
+| Setting | Default | Notes |
+| --- | --- | --- |
+| `backup_enabled` | true | Master scheduler switch |
+| `backup_destination_type` | `'local'` | `'local'`, `'s3'`, or `'rsync'` |
+| `backup_destination_path` | `'/backup'` | Local destination |
+| `backup_database_inline_dump` | true | Inline DB dump on every run |
+| `backup_include_archived` | false | Gate `events/archived` |
+| `backup_incremental` | true | Skip unchanged files (checksum-tracked) |
+| `restore_allow_force` | true | Permit Force Restore via the wizard |
+| `restore_require_pre_backup` | true | Take a pre-restore safety snapshot |
+| `restore_verify_checksums` | true | Verify file checksums after restore |
+| `restore_email_on_completion` | true | Notify admin when restore finishes |
+| `restore_retention_days` | 30 | How long pre-restore snapshots survive |
+
+Most settings are exposed in the **Backup → Configuration** tab. Less common ones can be set via SQL.
+
+## Troubleshooting
+
+### "Run Backup Now" fails with `No database backup available`
+
+The inline DB dump was disabled AND no recent scheduled dump exists. Either re-enable inline dumps (set `backup_database_inline_dump = 'true'`) or configure a scheduled DB dump that completes within the staleness window (default 26h).
+
+### Backup History row says "completed" but shows 0 files
+
+This is the legacy of a pre-2026-05 install where the walker was hard-coded and missed paths. After upgrading, the new walker captures everything per `backup_paths`. The 0-file row is historical — new backups will count correctly.
+
+### Restore wizard shows "No backups found"
+
+The wizard's disk discovery looks in `backup_destination_path` + its `manifests/` subdirectory. If you moved manifests elsewhere or your bind mount points at a different host directory than expected, the discovery won't find them. Check `backup_destination_path` in the Configuration tab matches reality.
+
+### Restore completes but login fails
+
+Caused by the pre-2026-05 dead-pool bug — fixed in the current image. If you're on a stale image and still see this, restart the backend container once:
+
+```sh
+docker compose restart backend
+```
+
+Then try logging in again.
+
+### Install-from-backup: boot log shows no `Install-from-backup:` lines
+
+Check that the trigger file is actually visible from inside the container:
+
+```sh
+docker compose exec backend ls -la /backup/RESTORE_ON_INSTALL
+docker compose exec backend cat /backup/RESTORE_ON_INSTALL
+```
+
+If `ls` reports the file but the hook didn't run, the most likely cause is that the trigger pointed at a manifest that doesn't exist. The hook silently returns when the manifest path can't be resolved. Verify the path inside the file matches an actual manifest:
+
+```sh
+docker compose exec backend ls -la /backup/manifests/
+```
+
+### Install-from-backup: restore fails and leaves the trigger file in place
+
+This is the intentional behavior — fix the input, then restart the container to retry. The boot log will surface the underlying error (e.g. corrupt manifest, missing database dump file, validator warnings without the force override).
+
+Common failure modes:
+
+- **Backup is files-only** (`database.backup_file = null` in the manifest). Pick a different backup or proceed with caution via the admin wizard, knowing you will restore files only.
+- **Manifest path mismatch.** The path in the trigger file points at a manifest that doesn't exist. Either fix the path or use the empty-file auto-pick variant.
+- **Existing data** without the force override. Either start from a truly empty install (`docker compose down -v`) or set `INSTALL_FROM_BACKUP_FORCE=true`.
+
+### How do I disable install-from-backup entirely?
+
+Don't create a `RESTORE_ON_INSTALL` file. Without the trigger, the hook is a no-op on every boot. There is no separate "off switch" because the feature is opt-in by design.

+ * BackupIntegrityCard — on-demand verifier for CRM document artefacts.
+ *
+ * Walks every `*_path` column on quotes / contracts / invoices and
+ * confirms (a) the referenced file exists on disk, (b) where a SHA-256
+ * is stored, the file's bytes hash to the expected value. Surfaces
+ * three failure buckets:
+ *
+ *   - missing         — `*_path` set, file not on disk (broken FK)
+ *   - hashMismatches  — file exists but bytes don't match the stored hash
+ *   - existsButNoHash — verified by existence only; weaker evidence
+ *
+ * Designed to be portable. Currently embedded as a tab on
+ * `BackupManagement.tsx`; when the System Health page (backlog item)
+ * lands, this same component can be lifted there without changes.
