Nightly eval REGRESSION: benchmark 'cli_args' passed ALL trials in the previous run but failed BOTH trials on 2026-07-18.
Error category: [logic_error]

Results: /tmp/nightly_eval_20260718 (prev: /tmp/nightly_eval_20260717_rag_on/agent)
It was solid last night, so this is a fresh solid->broken regression — investigate.

Closing after a stale-regression audit (2026-07-20, prompted by #417 — thanks @yashpatel1230): this regression did not persist. The benchmark passes in subsequent runs (v0.30.0 baseline, 2026-07-19) and the nightly bot — which re-flags any regression that persists — did not re-flag it in the latest run (2026-07-20). Verdict: transient/model-variance, recovered. Process fix landing today: the mission loop's triage now closes the corresponding issue whenever it refutes or resolves a flagged regression, so stale alarms no longer linger open.
