+/**
+ * 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.
