hot_reloader.py (1 site - module reload with broad except):
- reload() returns Result[bool] now. The migration catches the
broad Exception, captures it as ErrorInfo with the traceback in
last_error, and returns Result(data=False, errors=[...]).
- reload_all() returns Result[bool]; aggregates per-module errors.
- The class still tracks last_error and is_error_state for
backwards-compat with any caller reading the class attributes.
warmup.py (5 sites):
- L139 (on_complete callback fire): was except ...: pass.
Now logs to sys.stderr with the exception.
- L215 (_record_success callback fire): same.
- L249 (_record_failure callback fire): same.
- L276 (_log_canary stderr.write): was except OSError: pass.
Now logs the OSError itself.
- L300 (_log_summary stderr.write): same.
startup_profiler.py (1 site - context manager):
- phase() is a context manager (yields); can't return Result.
The except inside the finally block now logs the OSError.
Tests updated for hot_reloader to check result.ok and result.data.
