## Verification
- Backend: 38 unittest tests pass.
- Backend: 54 unittest tests pass.
- Independent M1 review: **PASSED**; no concrete security or logic blockers.
- Reviewer suggestions: set `PAPER_COOKIE_SECURE=1` outside local HTTP; replace in-memory sessions before multi-worker deployment.
- M1 reviewer backlog: add schema-drift, duplicate/reordered-row, and malformed-vintage regression fixtures.

- Price snapshot normalized 9 symbols with adjusted close and provider-derived trading dates; quality is explicitly `revised_vendor_history` and `point_in_time=false`.
- Backtest gate requires both independent vintages and point-in-time prices.
- Independent M2.4 review: **PASSED**; no concrete security or logic blockers.
- Research runner persists blocked/ready reports with frozen input IDs, hashes, configuration and gate reasons.
- Revision-aware readiness counts `(source_id, published_at)` once and runner selects the latest revision only.
- Event-study defaults to next trading-session execution and handles non-trading event dates without skipping the first session.
- Paper ledger persists atomically under ignored `backend/data/paper/ledger.json` when configured.
- Live API `0.5.0` created and replayed the same blocked Tourism research report; UI served the research-run panel and human-readable gate reason.
- Independent M2.5 review: **PASSED**; no concrete security or logic blockers.
- Browser visual capture was blocked by Chrome remote-debugging permission; no permission dialog was clicked.
