feat(messaging): ADR-0030 P2 — subscription + preference#1444
Merged
Conversation
Adds the Layer-3 preference filter so users can mute notification topics/ channels, with admin-global defaults and mandatory-topic bypass. - sys_notification_preference: per (user_id, topic, channel) toggle; user_id='*' = admin-global default, a real-user row overrides it; topic/channel support '*' wildcards; unique (user_id, topic, channel). digest/quiet_hours fields for P3. - sys_notification_subscription: standing subscription of a principal to a topic (object + schema now; subscription-driven fan-out is a follow-up). - PreferenceResolver wired into emit() between recipient resolution and fan-out/enqueue. Most-specific-wins (user→*, topic→*, channel→*; default ON). Mandatory topics bypass (configurable, exact or prefix.); fail-open on no data / lookup error so a preference outage never silently drops notifications. emit() now filters the (recipient × channel) matrix per user. - Both objects registered by the plugin and contributed to the Setup app Configuration nav slot (ADR-0029 D7). Tests: service-messaging 66 passing — adds preference-resolver.test.ts (resolution matrix) + an emit-level mute/mandatory-bypass test. https://claude.ai/code/session_015pRGvrm3zrk5m8YvZhkAmF

Summary

What changed
Objects
sys_notification_preference— per(user_id, topic, channel)toggle (enabled, plusdigest/quiet_hoursfor P3).user_id='*'rows are the admin-global default; a real-user row overrides it;topic/channelsupport*wildcards. Unique(user_id, topic, channel).sys_notification_subscription— standing subscription of a principal (role:/team:/user:/id) to a topic. Object + schema land now; subscription-driven fan-out (expand a topic's subscribers when a producer emits without explicit audience) is a documented follow-up.PreferenceResolver (wired into
emit())Inserted between recipient resolution (P1) and fan-out/enqueue:
user → *,topic → *,channel → *, default ON. A user's row beats the global*default.MessagingServicePlugin({ mandatoryTopics }), exact match orprefix.(e.g.security.). Users can't mute these.emit()now filters the(recipient × channel)matrix per user (different recipients can accept different channels);fanOut/enqueueDeliveriesiterate per-recipient targets.Wiring
Both objects are registered by
MessagingServicePluginand contributed to the Setup app's Configuration nav slot (ADR-0029 D7), so they appear in REST/Studio only when messaging is installed.Acceptance (per build spec)
