Triage (fable-O, 2026-07-18 evening)

• Reproduced NATIVELY at HEAD (938c0154+): test passes (cast=107 / after nil / destroy 7, exit 0), repeatedly.

• The bad-range STARTS at daf8d692 — a docs-only commit (rainy-day claim wording) that cannot change codegen.

• The log tail shows the suite's other jobs ok and then a bare Terminated — the [[project_borg_red_harness_race_not_regression]] signature (job killed by the harness under load, not a wrong-output failure).

• Verdict: very likely harness race/timeout, not a regression. Leaving OPEN for the watcher's idle bisect to confirm; close on the next borg GREEN of this job.

• 2026-07-19 (backlog sweep) RESOLVED. Confirmed harness race (not a compiler regression); watcher marked FIXED at d9cc9184, test passes natively at HEAD. Close condition (next borg GREEN of the job) met.

• 2026-07-19 — resolved, commit d9cc9184.
