📝 WalkthroughWalkthroughThe interruptible sleep helper now uses a three-argument progress callback. Fixed duration parameters were removed from client operations and retry paths. The client parses server p50 and p90 duration headers, stores estimates, and displays queue-aware estimated progress. Progress and price extraction failures no longer stop polling. Progress-bar interruption races are handled during updates and completion. Upload retries now display conditional wait progress. Priority: ⬇️ Low Merge Risk: 🔵 Low · up to A narrow cancellation race can discard a completed result, while extractor failures may silently suppress progress or price updates. Both should be corrected, but their impact is bounded. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

In `@comfy_api_nodes/util/client.py`:
- Around line 442-446: The price extraction flow around price_extractor must
stop catching arbitrary callback exceptions: isolate response-model validation
from extractor invocation, catch only the validation failure and preserve the
None fallback for malformed poll data, while allowing extractor defects such as
RuntimeError to propagate. Apply the same separation to the corresponding
progress extractor handler.

Learning: In `comfy_api_nodes/util/client.py`, `poll_op_raw` treats `price_extractor` and `progress_extractor` failures as best-effort display failures. The handlers intentionally catch callback exceptions, log the failure, and continue polling so an extractor defect cannot abort retrieval of an already-submitted, billable task.

Terminal lines drop the remaining tail (also fixes the bogus tail on static-param Completed lines).progress_extractorget an estimate-driven bar: 0→90% over p50, 90→95% to p90, hold at 95%, 100% only on terminal success. Provider-native progress owns the bar as today.Also in the stack:
estimated_durationplumbing (display-inert, zero callers).ProgressBar.update_absolutecan raiseInterruptProcessingException(aBaseExceptionthat clears the interrupt flag), escaping every guard inpoll_op_raw, so a cancel racing the final poll discarded a completed, already-billed result. Completion now supersedes such a cancel; non-terminal races re-arm the flag so the normal cancel/cancel_endpointflow runs. Price/progress extractors tolerate transient poll bodies likestatus_extractoralready does.Servers that don't emit the headers (prod-v2 until the flag flips) get exactly today's behavior.
