+"""rule_moment_judgments.misfire — a mount reported as arriving where it does

+
+Revision ID: 0119
+Revises: 0118
+Create Date: 2026-10-05
+
+The open-after-moment signal proposes a mount; nothing proposed taking one
+off. This column is the evidence for that direction: each time a session says
+a mounted rule arrived at a moment where it did not apply, the report is
+counted here per distinct day, with its reason and the action that reached
+the moment. At the bar it becomes an unmount proposal for the operator.
+
+A column on the judgment row rather than a table of its own: a misfire is
+always about a (rule, moment) pair that is mounted, and that pair already has
+its row. Nullable and no backfill — nobody has reported a misfire yet.

+## When a mounted rule arrives and does not apply
+
+A mount delivers its rule at every occurrence of the moment, so a mount that
+is wrong is noise every time — and a rule you read and set aside leaves no
+trace anyone else can see. When a rule arrived *at* a moment, you read it,
+and it has nothing to do with what you were doing there, say so with
+`rule_misfired(rule_id, moment, why, reached_by)`: one call, nothing asked of
+the operator. Name the action the line said reached the moment, and say what
+you were doing, because the reports are what the operator decides from —
+whether the rule does not belong at the moment, or one action is reaching it
+that is not that moment here.
+
+Reports gather across days. Once a rule has them on three, the response
+carries a line asking you to offer the fix, and the operator sees it under
+Settings › Moments too: `judge_rule_moments` `reject` takes the rule off,
+`unmap_action` stops the action reaching the moment, and `confirm` keeps the
+mount and ends the question. A rule that applied — even one you were already
+following — is not a misfire, and a rule that arrived by its words rather
