fix(libsy): avoid zero exit tool-signal matches - #651
Conversation
|
WalkthroughThe change adds numeric-aware detection for generic exit-code and exit-status phrases. Zero values remain clean. Nonzero values receive ChangesExit status detection
Priority: ⬇️ Low Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to Exit-status text now keeps zero results clean and classifies nonzero results as soft errors. The behavior is covered by targeted tests, but the changed classifier and parsing helpers still need the requested documentation before the change is fully ready. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Summary
Process exited with code 0tool output as clean instead of a softexit_nonzerosignal.exit code 1,exit status 3, andProcess exited with code 127still produce the intended soft signal.Why
In the DeepSWE stage-router smoke run (
ev_a25b67ed36f8428bb751958f73, trialtask__8Z5QzSd), the Codex shell transcript shape included successful results likeProcess exited with code 0. The old substring patternexited with codematched those clean results asexit_nonzero, producing a false soft-error signal on nearly everyexec_commandresult. That explains the observed capable routing confidence around0.613357..., which is exactly the no-production + soft-severity path, and inflated Sol routing during otherwise clean tool use.Against that downloaded smoke transcript, this change reduces
exit_nonzeromatches from 106 to 14. The remaining 14 are actual non-zero exits from failed patch/test commands. Rolling recent-window severity-positive positions drop from 112 to 32; the remaining windows are around real failures and the knownapply_patch: command not foundhard signal.Validation
