A rule mounted on a moment now reaches the session when an act reaches
that moment, with no semantic match involved:
- run_moment_arm on the pipeline: a lookup, not a ranked search. Each
line names the moment and the act that reached it ("at work.deliver,
reached by `git push`"), so a misfire is visible where it lands and
can be unmapped in-session. A repeat is cited, not quoted; fresh
rules are recorded surfaced under source moment_rule with the moment
in detail. No retrieval_logs row, as for the other lookups, so no
latency is persisted for this arm.
- rule_scope: a rule's home clause, moved out of semantic_search_rules
so the moment lookup scopes by the same one.
- rulebooks.rules_on_moments / mounted_moments.
- The plugin door: a catch-all PreToolUse hook (scribe_moment.sh). It
keeps /moment-tools' answer on disk for five minutes, so a call to a
tool that cannot reach a mounted rule sends nothing, and an install
that has mounted nothing sends one request per window. It shares the
rules ledger with the other arms and fails open silently.
- The MCP door: Scribe's own tools named by the shipped mappings carry
moment_rules in their response, so a client without the plugin gets
them too. The hook skips those tools. A guard pins the attach on
every one.

rule_moments (migration 0117) records which moments a rule arrives at, by
catalog name, cascading with the rule. rule_detail, the one seam every
rule door already returns through, gains moments beside system_ids: None
leaves the mounts alone, a list replaces them. get_rule and both
list_rules doors read them back, batched per page.
All five MCP rule/preference writes and the three REST ones take moments
and validate them before their create or update. An unknown name is
refused with the catalog listed and leaves no half-made rule behind; a
parity test pins that ordering on every door.
Backup v22 carries the mounts as a join table remapped through the rule
map; a real-Postgres round trip checks they land on the restored rule.
