tools/watchdog-notice.mjs is a one-shot reader. It reads Idunn's incident
store unlocked with SingleFileMessagePackBackingStore.pullAll, sends one opening
and one closing DM per incident through bifrost-bridge.mjs, and keeps a
bifrost.watchdog_notice_execution.v1 journal: a running entry becomes unknown
and is never re-posted, a failed one is retried with the same nonce up to five
times, terminal entries are pruned once Idunn retires the incident. The exit
status is the delivery-failure signal.
discord-dm accepts --nonce (at most 25 chars) and sends nonce with
enforce_nonce so a retry inside Discord's window returns the original message.
The tests run the CLI against the store bytes Idunn wrote (fixture from
GameCult/Idunn 7f7528b3) with a counting bridge double, and once through the
real bridge with fetch stubbed. docs/watchdog-notice.md states the CultLib
>= 8cb3b728 floor.
