Repository guidance

Inherit the root and Furious/AGENTS.md. Consult the Interface and Models guides when changing their contracts. This scope owns restoration, migration, ordering, and persistence; workflows and presentation remain outside it.

• Repositories restore, migrate, order, and persist profiles, subscriptions, routings, and TUN settings. They do not own network workflows, controller state, test schedulers, or presentation.
• Storage owns one application-lifetime backend per collection and exposes live mutable collections for compatibility. Do not add a second cache/snapshot authority. Prefer named repository mutations so validation and commit boundaries can move behind the repository over time.
• Preserve stable profile/subscription IDs, subscription ownership/key, ordering, unknown fields, and legacy schemas. Active row/index and display text are compatibility/presentation state, not identity.
• A restore failure remains observable. Automatic cleanup must not replace unreadable persisted bytes with an empty fallback; only an explicit successful replacement may do so. Root decoding, individual-record hydration, and later serialization are separate failure boundaries. Test malformed records inside a valid root as well as malformed roots; the existing root fallback is not a guarantee that every record error is recoverable.
• Stage fallible decode/migration before live mutation. Subscription reconciliation currently belongs to Service/SubscriptionSync.py and commits through the compatibility live collection: matched managed profiles retain object/profile identity and local metadata, removed profiles become stale, and unrelated groups remain intact. Do not add a second reconciliation algorithm here merely because persistence belongs to this scope.
• Distinguish a live-collection commit from serialization/flush and subsequent controller effects. The compatibility collection can change before it is flushed; a successful in-memory synchronization is not proof of an atomic disk transaction. Preserve explicit flush/cleanup behavior and report failures at the boundary that actually failed. Batched UI commands may commit several live mutations; cancellation prevents later batches without restoring already committed ones. Do not impose whole-command atomicity without changing callers and failure semantics.
• Moving a profile between subscription displays does not automatically make it remotely managed; preserve the explicit distinction between local membership and synchronization ownership.
• Verify legacy/current/unknown-field round trips, malformed roots, restore-failure preservation, ordering/stable identity, group isolation, reconciliation commit behavior, and persistence in temporary QSettings namespaces. Use tests/test_repository_contracts.py and tests/test_subscription_sync.py to revalidate this scope. Reordering a filtered view must preserve hidden slots and relocate activation by profile ID, not by its former row.
