## Summary
- make SQLite-to-PostgreSQL cutover retryable, fail-closed, versioned,
and transactionally serialized
- isolate migration sessions from runtime traffic and apply schema
upgrades through `0002`
- enforce tenant ownership across automations, analytics, activity,
usage, agent runs, evals, and todos
- replace expired SQLite-only coverage with PostgreSQL parity and
concurrency coverage
This is PR 1 of 2. The stacked follow-up restores PostgreSQL parity for
CLI, engine, dashboard, and bundled integrations.
## Verification
- `pnpm check:changesets --strict`
- `pnpm --filter @fusion/core typecheck`
- migration schema, connection, and SQLite cutover suite: 57 tests
passed
- `pnpm test:gate`: 463 tests passed
## Post-Deploy Monitoring & Validation
- take a restorable PostgreSQL backup before deploy
- confirm `fusion_schema_migrations` contains `0002`
- confirm each expected project has a complete
`fusion_sqlite_migrations` row
- verify no null or empty tenant ownership in automations, activity
logs, agent runs, and usage events
- monitor for ownership inference failures, cutover verification
failures, and migration session errors
- restore the backup for data rollback; do not downgrade the
tenant-isolation schema in place

## Summary by CodeRabbit
* **New Features**
* PostgreSQL-backed analytics and live dashboard metrics are now
project-scoped (activity, tools, monitor, signals, and live snapshots).
* Evaluation runs and scheduled eval batches received lifecycle
improvements (ordering, updates, and execution flow).
* Todo list changes now emit events; WhatsApp persistence and
project-scoped roadmap data are supported.
* **Bug Fixes**
* SQLite-to-PostgreSQL cutovers now fail safely with stronger
verification, serialized cutover handling, and safer project ownership.
* PostgreSQL backend writes and reads are now strictly project-isolated
and fail closed when project context is missing.

- Add eval score category types and exports in core with store support and coverage
- Implement engine evaluator evidence extraction and persistence with dedicated tests
- Update evaluator flow and cron wiring to record evidence alongside eval runs
- Refresh architecture, storage, and eval docs for evidence and categorization behavior
Fusion-Task-Id: FN-3391
Completes typing for the scheduled evaluator integration in the cron runner and project engine, with corresponding test updates in the evaluator test file.
Fusion-Task-Id: FN-3389
Introduced a new evaluation persistence layer in `@fusion/core` with domain contracts, SQLite-backed storage APIs, and retention/window-rollup support, wired through the core store and documented in the architecture and storage docs.
