## Prompt

The human reported repeated readiness without first-message relay,
specifically after first attempting an invalid .usdm. FQME and then
the corrected .usdtm. one. They requested distinct log messages for
receive starvation versus local backpressure.

## Response summary

Add phase-specific WARNING messages for each elapsed relay-loop
deadline, with URL, timeout duration, accumulated count and reset
threshold. Leave the existing shared receive/send deadline and
counter/reset semantics intact. Do not claim that connected/ready
sockets alone establish parsed quote recovery.

Read-only invalid-venue tracing found the usd substring check in
Binance get_mkt_info() accepts USDM while retaining it in MktPair.
Client.bars() later uses that market identity against canonical
USDTM keys. Backend stream startup precedes history startup and
sampler consumption. A relationship to the corrected-feed stall
still needs runtime evidence; neither venue handling nor task
lifetime behavior was changed by this diagnostic patch.

## Files changed

- `piker/data/_web_bs.py`: track and report the timed-out operation.
- `tests/test_websocket.py`: real silent-source and blocked-sink cases.
- This prompt provenance pair.

## Verification

15 selected Binance/websocket cases passed. The new cases exercise
real TCP, websocket handshake and relay behavior, replacing only
log observation. A zero-capacity relay deliberately forces the
local-send case; the source-silent case never receives a payload.
git diff --check passed. No live provider/daemon operations run.

## Human edits

No direct source edits observed. The human supplied the critical
invalid-symbol-then-corrected-symbol trigger and requested the
phase distinction; live testing and task acceptance remain theirs.
