Subject: [PATCH] feat(moments): a mount that keeps arriving where it does not
 apply proposes its own removal (milestone 458 step 7b, #4955)

The open-after-moment signal proposes a mount; nothing proposed taking one
off, so a wrong mount was noise at every occurrence until someone happened
to notice. rule_misfired(rule_id, moment, why, reached_by) records a report
against a MOUNTED pair, counted per distinct day (the MCP door carries no
session id) on a new rule_moment_judgments.misfire column (migration 0119,
backup v24). At three days the response carries a line asking the agent to
offer the operator the fix - reject takes the rule off, unmap_action stops
the action reaching the moment, confirm keeps the mount and stops the
asking - and Settings > Moments lists it as an unmount proposal with the
reasons and the actions that reached it. A re-mount clears the count.

Taught in moments.md, missed-retrieval.md and the reply hold's wording.

+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
