 ## [0.1.0] - Unreleased
 
 ### Fixed
+- Under OAuth2, per-recipient checks (alert visibility for external channels, follower record access, audience sessions) never worked: they used token-less automated sessions, which OAuth2 rejects, so external sends fell back to the conservative rule. When the host declares the QQQ `alerts` service principal (`AlertsQBitConfig.withServicePrincipal`, default `alerts`), these checks run on the recipient's behalf through it: the recipient's current access intersected with the principal's. Alert recording and routing bookkeeping stay on the system session, so alerting does not depend on the identity provider being up. With no principal declared, behavior is unchanged. Needs the QQQ release with service identities (qqq#1255, #1256).
+- Audit noise: every monitor run (lease claim, then run result) and every reminder check wrote a "Record was Edited" audit (about 7,000 `alerts_monitor` and 1,800 `alerts_alert` audits in 6 hours on one production host, most with no field details). Engine updates that touch only bookkeeping fields (`RuntimeFields`: monitor `claimedBy`, `claimedUntil`, `lastRunAt`, `nextRunAt`, `lastStatus`, `lastValue`, `lastError`, `lastElapsedMs`, `consecutiveFailures`, `conditionSince`; alert `timedNotificationCheckedAt`, `lastNotifiedAt`, `recordRefCount`) are written with `omitDmlAudit`. Configuration edits, raises and alert state changes are audited as before, as are UI and API edits of any field.
+- Read the QBit metadata version from the Maven-filtered artifact version so release builds report their release version.
 - Record-view child lists (e.g. a notification's Recipients) failed with "Error in JSON Serialization": the child table's meta-data includes the qbit config, and `AlertsQBitConfig.getRuntime()` points at a runtime that points back at the config, so Jackson recursed to its 1000-level nesting limit. `getRuntime()` and `getAudienceResolver()` are now `@JsonIgnore`, as in the other qbits' configs. A regression test renders and serializes every child-list widget.
 
+### Added
+- Ship the full host-neutral Alerts help bundle through QQQ 4.1.0-RC.7 core registration, replacing the temporary loader. Cover owned tables, fields, actions, jobs, widgets and possible-value sources with a bundle coverage gate; support HOST overrides and hosts without help tables.
+- Starter defaults changelog `alerts-defaults.changelog.sql` (insert-only, guarded): the `in-app` and `email` channels and the `alerts` and `other` groups, equal to what the runtime creates on first use. Tested through real Liquibase on H2.
+- Help for the Alerts app and every `alerts_*` table (`help/qbit-alerts.yaml`): what the table is for and how its rows get created, shown when it is empty.
+- A Setup card first on the Alerts home (alerts admins): each configuration table, its state and the next step.
+- `AlertsTablesGuardrailTest`: every table is used by runtime code, seeded or listed as starting empty with a reason, and has help.
+
+### Fixed
+- A group's `ownerTeamId` was stored but never read. An alert that no subscription matches (WARNING and above) now goes to the owner team of its group, or of the nearest parent group that has one.
+- A user's `defaultChannelIds` was stored but never read. It now adds the chosen external channels to the bell (unless In-App is off) for subscriptions that name none.
+- Alert types, groups and default monitors also sync on the first bell request, so those tables are not empty on a running install.
+
 ### Changed
 - Keep reminders and escalations immediate for digest subscribers while applying pause and quiet hours to their push channels. Preserve team audience resolution, mute scopes, both scheduled jobs and changesets 21-27.
 - Apply user pause and local quiet hours to personal push channels (email, email lists and other non-IN_APP channels), including team members, with logged suppression reasons and a configurable quiet-hours severity bypass. The in-app bell remains unaffected, including digest delivery. Channel subscriptions are unaffected.
@@ -36,6 +51,7 @@ All notable changes to this project are documented here. The format follows Keep
 - Apply reminders and escalation (#27, part 2): a minute-based hidden job sends due reminders, advances ordered USER/TEAM/CHANNEL escalation steps, and caps final-step repeats. Acknowledgement, snooze, resolution and mutes stop both; reopening restarts escalation. Delivery, events and progress commit together, with a persisted same-minute checkpoint.
 - Add admin escalation policy and step tables, child step lists, and type/group policy links in guarded Liquibase changesets 23–26. Type policies override group policies. CRITICAL reminders default to 60 minutes; explicit zero turns them off.
 - Keep EXPIRED reserved and remove it from selectable resolution values because the design specifies no expiration rule.
+- Per-notification email opt-in via recipient email status `REQUESTED`: immediate delivery without a standing category preference. It still honours the category email minimum severity, the user pause (SECURITY bypasses) and quiet hours (held until they end, for up to a day), is skipped when no address is known, and is never emailed for ALERT notifications.

   - Slack (an Incoming Webhook, Block Kit)

+Every table has help that says what it is for and **how its rows get created**, shown on the table screen and when it is empty (`help/qbit-alerts.yaml`). Alerts admins also get a **Setup** card first on the home that lists each configuration table, whether it is set up, and the next step.

+## In-app help
+
+The producer registers [`help/qbit-alerts.yaml`](src/main/resources/help/qbit-alerts.yaml)
+with QQQ's help-bundle registry. It covers the Alerts app, tables and fields,
+actions, scheduled jobs, widgets and possible-value sources. QQQ syncs the bundle
+when the host installs the help-content tables; registration is harmless without them.
+
+Hosts can override individual entries by registering their own bundle with
+`layer: HOST`, using the same entry `key` and `role` (default `ALL_SCREENS`).
+Register it with `HelpBundles.register(qInstance, "help/my-host.yaml")`. Host
+bundles take precedence over this `QBIT` bundle, and edits made by users remain protected.
+
+`AlertsTablesGuardrailTest` runs `HelpBundleAssertions` against the produced instance
+to check owned-object coverage, summary length and live references. It also requires
+widget and possible-value-source help and preserves the table empty-state guidance.

+   - include: { file: db/liquibase/qbit-alerts/alerts-defaults.changelog.sql }

+2. **Behavior changes to know about.**
+   - A group's **Owner Team** is now used: an alert at WARNING or above that no subscription covers (by scope and severity) is sent to that team's members; follow-ups (resolved, reminders) go only to members who were told about the raise. Hosts that never set an owner team see no change.
+   - **Default Channels** on My Alert Settings is now used for subscriptions that name no channels. The bell stays whenever In-App is not turned off; the list replaces the built-in email choice with the channels you chose (unknown ids are ignored). Hosts that never set it see no change.
+   - Alert types, groups and default monitors now also sync on the first request of the bell, not only on the home or the first signal.

+--     absent, so an administrator's edits always survive and nothing is updated;
+--   * no secrets: the channels hold settings only, never a secret;
+--   * portable SQL (PostgreSQL and H2): INSERT ... SELECT ... WHERE NOT EXISTS;
+--   * every changeset has a precondition on its table, so a host that has not
+--     created a table yet simply skips it (MARK_RAN).
+-- The runtime creates the same rows when they are missing (AlertChannels.defaultChannel,
+-- AlertTypeSync.ensureGroup); this file only makes them exist from the first deploy.
+-- Alert types, monitors, escalation policies, teams and subscriptions are NOT seeded
+-- here: types and default monitors are declared by the installed qbits and synced at
+-- startup of the Alerts home, and the rest is the host's own people and policy.
+-- AlertsDefaultsChangelogTest runs this file twice against a fresh schema.
