## Final verdict: **PASS**

No blocker remains from prior findings **#4** or **#6**. The empty-portfolio regression is also fixed.

- **#4 — Cache exchange validation: PASS**
  - `_has_fresh_price_for_target()` now applies `exchange_matches(...)` before accepting either the mapped primary provider or the yfinance fallback:
    - `src/jarvis_finance/services/market_service.py:128-159`
    - Exchange rejection: `:153-154`
    - Provider/yfinance handling: `:155-158`
  - Direct isolated probe:
    - Primary provider + correct SIX exchange: accepted
    - Primary provider + wrong NASDAQ exchange: rejected
    - yfinance + correct XSWX alias: accepted
    - yfinance + wrong NASDAQ exchange: rejected
  - Existing regression coverage: `tests/unit/test_sprint11_portfolio_completeness.py:86-105`

- **#6 — Authoritative frontend cutoff: PASS**
  - `loadPositions()` takes `as_of` from the backend summary, overriding the locally derived quote-date value:
    - `frontend/src/pages/EquityPage.vue:162-169`
  - Batch retry passes `summary.as_of`:
    - `frontend/src/pages/EquityPage.vue:170`
  - Per-position retry and its follow-up batch pass the same `summary.as_of`:
    - `frontend/src/pages/EquityPage.vue:172-173`
  - Regression test verifies both paths continue using backend cutoff `2026-07-24` despite position quote dates being `2026-07-23`:
    - `frontend/src/pages/EquitySprint11.test.ts:42-58`

- **Empty portfolio: PASS**
  - Empty portfolios are explicitly incomplete/unavailable, with no total:
    - `src/jarvis_finance/services/equity_service.py:157-175`
    - `complete = bool(positions) ...` at `:161`
  - Regression assertion:
    - `tests/unit/test_sprint11_portfolio_completeness.py:156-160`

### Focused verification

- Backend: **2 passed**
- Frontend cutoff test: **1 passed**
- Direct provider/exchange probe: **all four control/rejection cases passed**
- `git diff --check`: passed
- Verified commit: `343b9bc9f4a1ea690e69aaa61fc01bba9d4a06cd`
- Files created or modified by this review: **none**
- Only issue encountered: initial backend command referenced a nonexistent worktree-local `.venv`; rerun through the available Python environment passed.
