Stage 1 — compiler/AST-backed persistence boundary enforcement — complete and verified.

Evidence:

• Code commit: 42fd818ac12a5a69860863b1549d736892df4d91
• CI #631 (42190831986): architecture, full web regression/build, Android compile/unit/instrumentation/reliability gates succeeded.
• TypeScript AST checks cover import graphs, aliases, feature entry points, IndexedDB/Dexie/Web Storage/Cache APIs and browser persistence-library imports.
• Kotlin compiler PSI checks cover Room DAO and direct SQLite access, with positive/negative fixtures.

Stage 2 — formal persistence and schema contracts — complete and verified.

Evidence:

• Code head: af2da94a4defccafa46e12143b08591650bb670e
• CI #727 (42197902329): architecture, complete web regression/build, Android build, unit, instrumentation, and Room reliability gates succeeded.
• Shared record-envelope v1 and backup snapshot v1 contracts; validation at application, browser/Room persistence, backup export and restore ingress.
• Dexie v5 and Room v3 ordered migration contracts, historical/adversarial fixtures, future-version rejection, and Work command/intent/state/event/outbox contract validation.
• Contract: docs/PERSISTENCE_SCHEMA_CONTRACT.md.

Stage 3 — real persisted-data cross-platform parity — complete and verified.

Evidence:

• Code commit: 6e11d75c3d9860f2d6632a6a443d33e7f1e4f869
• CI #741 (42203502104): architecture, complete web regression/build, Android build/unit/instrumentation, and Android emulator Room/workflow/backup reliability gate all succeeded.
• Web persists ordinary and pending-edge datasets in Dexie/IndexedDB, reads current records through DexieDriverWorkflowRepository, tests malformed-record rejection, restore/reopen equivalence, and produces a complete serialized projection oracle.
• Android CI waits for the web job and downloads the exact Dexie-generated oracle. Instrumentation persists equivalent records in on-disk Room, tests replay idempotency, snapshot export/replacement/restore, close/reopen, and compares the complete shared TypeScript projection output in WebView.
• Room v2 migration fixture now includes a legacy Log Book event; after 2→3 migration, Android projects the persisted migrated event and matches the Dexie historical-row oracle. Pending shift/trip edge states and malformed read-boundary rejection are also covered.
• The full serialized business output is compared, including event/group IDs, metric IDs/values/statuses, ordering, logical shift/day allocation, and integrity diagnostics.

Stage 4 — recovery and transaction guarantees — complete and verified.

Evidence:

• Initial implementation commit: 3f540d7d34de1340d274a52b97a3ca8ac5e8e8e2 (CI #748: run 42207494968).
• Follow-up audit fix: 30b179e5df0a056dd1bd003490c5d00492fd71c3. This closes the remaining native startup-entrypoint gap by gating generic RoomStore reads/writes and the overlay attention-status write through the process-wide recovery gate shared by Backup, DriverWorkflow, RoomStore, and the overlay service.
• CI #751: run 42211390874 passed architecture, focused recovery/reliability tests, complete web regression/build, Android assemble/unit/AndroidTest compilation, and the required Android emulator Room/workflow/backup reliability gate on the follow-up implementation head.
• Browser coverage: failure injection at event/state/intent/outbox writes; identity conflict and exact replay; pending-intent retry after IndexedDB reopen; interrupted export/replacement rollback; automatic checkpoint recovery after reopen; Timeline/trip-history rebuild from authoritative events after restore/reopen.
• Android coverage: Room transaction-trigger failure injection at Log Book/state/intent/outbox writes; duplicate/replayed completion and command identity checks; pending-intent recovery; ordered Room migration and injected migration rollback; restore replacement rollback; checkpoint recovery after Room close/reopen; backup snapshot revision validation.
• Contract evidence is recorded in docs/ARCHITECTURE_HARDENING_IMPLEMENTATION_CONTRACT.md and docs/TRANSACTION_AND_RECOVERY_CONTRACT.md.
• CI #752: run 42213013949 passed all architecture, web, and Android jobs on current PR head c58525732e9efa4d1ff0a12bd7e2433bd9749bf4 (the documentation-only Stage 4 evidence commit).

Stage 5 — integrated regression gate — complete and verified.

Evidence:

• Implementation commit: 376282f9fa6a0d912c866c1692f214909fed1d55.
• CI #753: run 42244490685 completed successfully on this exact PR head.
• The integrated regression job depends on architecture, web, and Android and explicitly fails unless all three report success.
• Architecture gate: success.
• Web gate: success — focused offline workflow/backup reliability regressions, complete web regression suite, Dexie-generated Timeline parity oracle, and production build.
• Android gate: success — debug/release assembly, Android test compilation, unit tests, Room/workflow/backup emulator reliability gate, and publication of Room schema history.
• Integrated regression gate: success.
• The unsigned release APK publication step was correctly skipped because this is a pull-request run; it is configured for merged main.

PR #13 remains draft and unmerged. No Workflow/Timeline UI, navigation, styling, cards, or shell redesign is included. Physical-device and live Dropbox/account acceptance remain separate deferred release gates.
