## Prompt

Address the Tuicr review by separating generic websocket reconnect
changes from Binance-specific work and testing the real reconnect task
hierarchy rather than a reimplementation.

## Response summary

Preserves structured cancellation and safe first-handshake retries in
`_web_bs`. Adds three focused regressions in a dedicated websocket test
module and packages them as an independent commit boundary.

## Files changed

- `piker/data/_web_bs.py` - restart handled handshake failures and let
  cancellation bypass the reconnect throttle.
- `tests/test_websocket.py` - exercise real reconnect startup, retry,
  and cancellation task paths with controlled transport boundaries.
- `ai/prompt-io/opencode/20260901T024235Z_e09e306a_prompt_io.raw.md`
  - retain the review prompt, generated-code summary, and verification.
- `ai/prompt-io/opencode/20260901T024235Z_e09e306a_prompt_io.md` - record
  structured provenance for the generic reconnect boundary.

## Human edits

The user identified that these changes were generic rather than
Binance-specific, required a separate commit and test module, requested
coverage of the real reconnect hierarchy, and corrected code prose to
refer to `trio` consistently. A follow-up review required the production
code to explain why `trio.Cancelled` bypasses the broad reconnect-error
handler and cite the regression which audits that teardown invariant.
