feat(moments): mount the corpus by proposal - a pass and an open-after-moment signal, both stopping at the operator (milestone 458 step 7, #4925)
A rule written before moments existed is mounted on nothing. Step 7 records,
per (rule, moment), whether it belongs there and who said so:

- rule_moment_judgments (migration 0118, backup v23): suggested / confirmed /
  rejected, from a pass, the signal, or an edit. Moment "" is "no moment fits".
- The pass: rules_to_mount lists unjudged rules; propose_rule_moments records
  suggestions that mount nothing; rule_moment_proposals and
  judge_rule_moments put them to the operator. A confirm mounts, a reject is
  kept so the pair is never proposed again. Same service behind REST and a
  "Waiting on you" panel in Settings > Moments.
- Edits are judgments: set_rule_moments, the one mount write path, confirms
  what was added and rejects what was removed in the same transaction.
- The signal: scribe_moment.sh keeps a per-session acts ledger; when a rule
  is opened, scribe_record_opened.sh sends the last three minutes of it to
  /api/plugin/rule-opened. The acts resolve through the install's mappings;
  work.run and work.change are not evidence. Counted per distinct session
  with lesson_rules' evidence model, and once due the open returns one line
  asking the reader to offer the mount.
- scribe_session_end.sh removes the session's scribe-moment files.

Plugin 2026.10.05.2003.

# Scribe — record that this session OPENED a rule, not merely saw it named (#4100).
#
# WHAT THIS CLOSES
#
# The rule arms keep a ledger of every id they have NAMED, and the injected
# line used to tell the reader "You saw it earlier this session". That claim
# was never checked. The line those arms emit is a TEASER — title, trigger,
# `get_rule(N)` — so a session can be named a rule twenty times and never read
# one word of it, and after a compaction the teaser is summarised away leaving
# nothing at all. The server was asserting something about the reader's
# context that it had no way to know.
#
# This is the observable half. PostToolUse fires for MCP tools (the event's own
# output schema carries `updatedMCPToolOutput`, which would be meaningless
# otherwise), so the `get_rule` CALL can be watched directly.
#
# WHY THIS IS NOT THE SELF-REPORT MILESTONE 386 REJECTED
#
# 386 ruled out asking the session whether it holds a rule, because a model
# asked "do you still hold rule 156?" will say yes and the answer is
# unverifiable self-report. That objection is about ASKING. This asks nobody:
# a tool call happened or it did not, and the harness reports it either way.
# Recording what a session DID is a different kind of evidence from believing
# what it says about itself.
#
# WHAT IT DELIBERATELY DOES NOT DO
#
# It does not prove the rule is still in context — nothing can, and a
# compaction can drop it moments later. That is why `.opened.ids` ages exactly
# like `.rules.ids` and is cleared on the same events (#3749): both ledgers
# describe a context that no longer exists once the context is destroyed. The
# claim it supports is only ever "you opened this, pull it again if you no
# longer hold it", which stays true in every case and carries its own remedy.
#
# SINCE MILESTONE 458 STEP 7 it also reports the open, with the calls that
# came just before it, so the server can learn which moments a rule belongs
# on (below). Silent on outage, like every arm that fires per call.
#
# EXIT 0, ALWAYS. This decorates a ledger; a bookkeeping failure must never
# turn a successful tool call into a hook error. Worst case the id is missed
# and the reader is offered a rule it already read — the cost of a wrong guess
# here is one extra line, in the direction that shows more rather than less.
