## Prompt

The user asked to land recent branch work in small chronological patch sets,
including missing tests. For Binance, the user required preserving the
existing committed topic patch through cherry-pick and placing newly found
correctness repairs in a separate follow-up boundary above the flake/xonsh
stack. The user also required every yielded stack layer to include a complete
`/commit-plan` with patch-specific checks.

## Generated code

> `git diff HEAD~1..HEAD -- piker/brokers/binance/feed.py`

Restricts Binance feeds to the supported one-symbol contract, renders direct
quote routes, separates L1 liveness from first-trade readiness, and derives
the contextual trade timeout from Trio's enclosing effective deadline.

> `git diff HEAD~1..HEAD -- piker/data/_web_bs.py`

Lets structured cancellation bypass reconnect throttling and ensures handled
handshake rejections retry before accessing connection-local cancel state.

> `git diff HEAD~1..HEAD -- tests/test_binance.py`

Adds deterministic regressions for symbol cardinality, route selection,
silent startup, immediate rejection, cancellation cleanup, aggregate-trade
schema evolution, delayed trades, and finite/infinite/tiny deadlines.

## Verification output

- Targeted Binance tests: `10 passed in 0.26s`.
- Ruff passes for all three changed Python files.
- `git diff --check` passes.
- Independent final review reports no actionable findings.
- No live Binance network probe was run.
