Round 2 review found two ways the "a human could merge this right now" invariant still leaked, both of which let state:needs-human land on a PR the button would refuse. The check-rollup classifier enumerated the outcomes that block and defaulted the rest to SUCCESS, so ERROR, CANCELLED and STALE fell through into green. Inverted to an allow-list of the outcomes that DON'T block (SUCCESS, NEUTRAL, SKIPPED, plus the pending set); everything else, including an outcome neither enum has today, blocks. The rollup mixes CheckRun.conclusion with StatusContext.state and an outcome the list forgets is one we cannot certify as mergeable — a false FAILURE parks the PR on the agent, a false SUCCESS invites a bad merge. The classifier also moved out of main() into checks_state(), which is why no fixture caught this: it was inline in the fetch loop and the jq itself was untestable. Once CANCELLED blocks, superseded runs must be dropped first — a re-run does not evict the run it replaced, and judging every entry would strand every re-run PR in needs-rebase. Each context now collapses to its newest entry, keyed on workflow + job name because a bare job name is only unique within its workflow. decide_state() returned from inside the bot loop on the first MISSING, so a STALE belonging to a later bot in BOTS was never read: a round that was both unfinished and staled came out needs-human with nothing bound to the head. The whole round is now collected before any precedence is applied, STALE ahead of MISSING. The MISSING-yields-to-an-explicit-human-request rule is untouched. Fixtures 29 -> 44, pinning the whole check-outcome enum, the supersede rule in both orders, and the mixed round at both ends of BOTS. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com> |
