run's own evidence, before the ledger is ever consulted. A matching
section only supplies a name for a `flake` verdict already reached; it
is not confirmation that this failure is one.
- **Out of scope: do not re-queue the PR.** Re-queueing needs a retry cap
(to avoid burning CI forever on a genuinely broken PR) and "is this
really a flake" is a judgement call a human should still ratify before
spending more CI time — this workflow's job ends at analysis and
bookkeeping.
- **Retriggering is optional but encouraged for flakes.** When you're
confident a failure is environmental and a rerun would likely pass, use
the retrigger helper to save the PR author a manual step. But exercise
judgment — if you're uncertain whether it's truly a flake, or if the
logs suggest the problem might recur, just recommend re-queueing in your
comment without retriggering. Never retrigger more than once per run.
