The pair is stored privately under state/when/ and hash-bound by a trust record the same way fm-check-register.sh binds a custom check, so a mutated spec is refused without executing anything. A durable exclusive fired marker claimed before the action makes restarts and re-polls unable to double-fire; every failure path (mutated spec, condition error past budget, expired deadline, failed action, uncaptured earlier fire) ends in a terminal captured outcome that wakes firstmate rather than a silent retry. Eligibility stays a firstmate judgment: only exact, safe, reversible actions may be bound, and judgment- needing or destructive actions keep the wake-and-decide flow. * no-mistakes(review): Harden when watcher concurrency, deadlines, timeouts, and output * no-mistakes(test): Bind watcher actions to registered executable bytes * no-mistakes(document): Correct condition-action watcher documentation * no-mistakes(document): Clarify outcome wake re-announcement * no-mistakes: apply CI fixes --- .agents/skills/process-event-sources/SKILL.md | 30 +- AGENTS.md | 3 +- bin/fm-procevent-lib.sh | 26 + bin/fm-procevent-when.sh | 504 ++++++++++++++++++ bin/fm-procevent.sh | 16 +- bin/fm-timeout-lib.sh | 18 +- docs/configuration.md | 6 + docs/scripts.md | 1 + docs/verification/process-event-sources.md | 6 +- tests/fm-procevent-when.test.sh | 406 ++++++++++++++ 10 files changed, 989 insertions(+), 27 deletions(-) create mode 100755 bin/fm-procevent-when.sh create mode 100755 tests/fm-procevent-when.test.sh diff --git a/.agents/skills/process-event-sources/SKILL.md b/.agents/skills/process-event-sources/SKILL.md index 705d4dc556..093272c41a 100644 --- a/.agents/skills/process-event-sources/SKILL.md +++ b/.agents/skills/process-event-sources/SKILL.md @@ -2,12 +2,14 @@ name: process-event-sources description: >- Agent-only procedure for registered process-to-event sources and their wakes. - Use before arming a long-polling source firstmate owns, and on any + Use before arming a long-polling source firstmate owns, before registering a + deterministic condition->action watch, and on any `procevent ` check wake. - Owns the arming commands, the durable result read, which wakes must be - routed to their adapter instead of acknowledged generically, the handled - acknowledgement contract, the one-owner rule, the precise durability - boundary, and the Lavish adapter's loss limitation. + Owns the arming commands, the condition->action eligibility boundary, the + durable result read, which wakes must be routed to their adapter instead of + acknowledged generically, the handled acknowledgement contract, the one-owner + rule, the precise durability boundary, and the Lavish adapter's loss + limitation. user-invocable: false metadata: internal: true @@ -15,7 +17,7 @@ metadata: # process-event-sources -Load this before arming a long-polling source, and whenever a `check:` wake carries `procevent `. +Load this before arming a long-polling source, before registering a deterministic condition->action watch, and whenever a `check:` wake carries `procevent `.

The common worker shape with the colon first (needs-decision: [key=x] note) silently folded its stated key into the shared "default" bucket, so two open decisions could collapse into one record and fm-send --resolve-key refused to close the decision it plainly named. A complete token at the head of the note is now an equivalent stated-key position for every keyed verb, shared by the whole-file and incremental folds through the one _fm_decision_key owner. The documented before-colon position wins when both are present, a token deeper in the note stays prose, a bare keyless line still folds to "default", and a stated-but-malformed slug is rejected rather than rewritten to "default". A consumed note-head token is stripped from the note so both positions yield identical records, and the incremental fold version is bumped so persisted cursors folded under the old interpretation are rebuilt from the authoritative log.
