• Enables Claude inline review comments.
• Updates the Claude CLI permission example.

File summaries

File	Summary and findings
planning/MARKET_DATA_DESIGN.md	Adds the market-data design reference. Findings: Moderate (3 votes): ticker removal must advance _version; timestamp=0 must be preserved; empty snapshots must be emitted; and in-flight polling must not re-add removed tickers. Moderate (1 vote): gate cache mutations after simulator shutdown. Moderate (3 votes): create a fresh router per factory call. Moderate (2 votes): normalize simulator tickers at the API boundary. Nit (1 vote): preserve held positions when removing tickers; initialize _client in the polling example; mark missing app wiring as pending or implement it. Nit (2 votes): update the test count from 17 to 19.
.github/workflows/claude.yml	Updates the commented CLI permission example. Nit (1 vote): retain the documented Bash(gh pr:*) matcher form.
.github/workflows/claude-code-review.yml	Enables inline review comments. Critical (3 votes): grant pull-requests: write; read permission causes comment creation to fail with 403.

• This changes the Claude Code permission matcher from Bash(gh pr:*) to Bash(gh pr *). The Claude Code command definitions use the command:* form for prefix matches; the space form is not the documented matcher and may fail to allow gh pr subcommands when this example is uncommented. Keep the colon form or use an exact command rule.

          # claude_args: '--allowed-tools Bash(gh pr *)'

• This contract is not met by the implementations shown below: after SimulatorDataSource.stop() leaves _sim set, add_ticker() can still call cache.update(), and both implementations' remove_ticker() still mutate the cache after stop. A request after shutdown can therefore change the cache. Gate mutators on a running state (or clear/disable it) and add a regression test.

        Safe to call multiple times. After stop(), the source will not write
        to the cache again.

planning/MARKET_DATA_DESIGN.md:1148

• This route example unconditionally calls source.remove_ticker() after deleting the watchlist row, but the next section says held positions must remain tracked for valuation. Following this earlier snippet would remove prices for open positions. Include the position check here too, or clearly mark this as pseudocode that must not be copied.

    await source.remove_ticker(ticker)

planning/MARKET_DATA_DESIGN.md:1280

• _poll_once() returns immediately when _client is None, but this example never assigns source._client; it will leave the cache empty and make both assertions fail. Add the same source._client = MagicMock() setup used by the actual test before calling _poll_once().

        source = MassiveDataSource(api_key="test-key", price_cache=cache, poll_interval=60.0)
        source._tickers = ["AAPL", "BAD"]

planning/MARKET_DATA_DESIGN.md:1068

• This section is presented as implemented, but the checkout has no backend/app/main.py or other FastAPI app wiring: nothing creates the lifespan, starts the source, or mounts this router. As written, /api/stream/prices and the background feed are not exposed despite the status claiming the design is complete; either mark this integration as pending or add the application wiring before making that claim.

## 13. FastAPI Lifecycle Integration

The market data system starts and stops with the FastAPI app via the `lifespan` context manager.

**In `backend/app/main.py`:**

planning/MARKET_DATA_DESIGN.md:1002

• The stream sends full snapshots, but this guard suppresses the event when the snapshot is empty. Even after a removal increments the cache version, deleting the last ticker will therefore never send {} and clients cannot clear their stale entry. Serialize and yield the empty snapshot whenever the version changes.

                if prices:
                    data = {ticker: update.to_dict() for ticker, update in prices.items()}
                    yield f"data: {json.dumps(data)}\n\n"
