- Around line 549-562: The helper _check_pr currently catches all Exception and
hides real errors; change its except clause to catch only CommandError (the
transient/network error documented by _pr_is_still_open) and return (pr, None,
exc) for CommandError, but let any other exceptions propagate (do not swallow or
return them). Update the except line in the _check_pr function to "except
CommandError as exc" (ensuring CommandError is imported/available) so the
executor.map loop still treats transient failures as kept but crashes on
unexpected failures.

Narrow _check_pr keep-on-error to CommandError only (in ralph_loop/cli.py lines 549-562).
_pr_is_still_open explicitly documents that transient/network failures raise CommandError, but _check_pr currently catches all Exception and routes it to the “Could not confirm…; keeping it in the fan-out set.” path—masking real regressions in the gh pr view/parsing logic. Catch only CommandError so unexpected exceptions fail fast.
Suggested fix
- def _check_pr(pr: int) -> Tuple[int, Optional[bool], Optional[Exception]]:
+ def _check_pr(pr: int) -> Tuple[int, Optional[bool], Optional[CommandError]]:
try:
return pr, _pr_is_still_open(pr), None
- except Exception as exc:
+ except CommandError as exc:
return pr, None, exc📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Catching Exception here changes behavior from fail-fast to silent fallback for all unexpected runtime errors in _pr_is_still_open (e.g., TypeError/ValueError from a bad refactor or malformed response handling), so the supervisor will keep and spawn PRs instead of surfacing a real bug. Before this change, only CommandError (the intended transient/CLI failure path) was tolerated; widening to all exceptions makes non-transient logic defects much harder to detect and debug.

💡 What: Updated
_filter_to_still_open_prsinralph_loop/cli.pyto useconcurrent.futures.ThreadPoolExecutorto check open status concurrently instead of sequentially.🎯 Why:
_pr_is_still_opentriggers agh pr viewsubprocess call which takes around 0.1s to evaluate. Using a sequential loop produces N+1 delays over large lists of PRs.📊 Impact: Reduces time taken to filter PRs by effectively ~90% for collections >10. A local simulation reduced execution time from 2.00s to 0.26s.
🔬 Measurement: Execute
