feat(status-pages): tables, snapshot contract and daily uptime counters - #1927
Customer status pages, 1/5: tables, snapshot contract, daily uptime counters
The foundation for public status pages that stay up while Maple is down. A page is served from a self-contained snapshot in edge storage. This PR adds the Postgres side, the shared snapshot contract, and the bookkeeping that later PRs publish from.
What's here
Tables:
status_pages, its components and incidents, incident updates, and the incident-to-component links;
uptime_monitor_daily, which holds checks, failures and checks taken while down, per monitor per UTC day;
status_page_cleanups, which queues the edge data a deleted page or old slug leaves behind.
Outbox: every change a visitor can see bumps status_pages.revision in the same transaction. The publisher (PR 3) republishes pages where revision > published_revision. The bump points in this PR are:
a monitor status flip, from batched checks or a heartbeat ping;
pausing, resuming or deleting a monitor;
an overdue heartbeat being marked down.
Daily counters: written inside the same transaction as the existing uptime state update. Only the reports that UPDATE actually applied are counted, so a retried batch is never counted twice. The 90-day bars therefore read from Postgres, not the warehouse.
@maple/domain/status-page:
the snapshot schema;
component status derivation, bars and uptime %, and the freshness rule ("live checks are delayed");
break-glass overlay merging, the token hash, and the edge storage keys.
Org delete: removes the new tables, and queues the deleted org's pages for edge cleanup.
Freshness: a page with monitors is live only while both of these are under 5 minutes old:
the publisher heartbeat;
the newest scheduled probe result. This is global, so a stopped prober turns every monitored page "delayed" instead of leaving it green.
Tests
packages/domain, vitest run src/status-page.test.ts, 13 passed. Covers:
derivation, bars, freshness, and a quiet healthy page staying live;
break-glass merging: "no change" keeps impact, an off-kind status is ignored, imported entries are skipped, and a follow-up reaches the incident it opened.
packages/backend, vitest run src/services/uptime src/services/org, all passed. Includes:
a daily count and page bump on a status flip, with a retried batch not double counted;
a bump on pause, resume and delete.
AlertsService.uptime.test.ts: a missed heartbeat counts a down check and bumps the page.
packages/db, parity.test.ts, 5 passed.
Typecheck is clean for primitives, domain, db and backend.

Walkthrough
Adds shared status-page schemas and snapshot rules, database tables for pages and daily uptime counts, and backend flows that aggregate applied checks and update page revisions. Organization deletion queues status-page cleanup records.

Layer / File(s)
Summary
Status-page contracts and snapshot rules packages/primitives/src/index.ts, packages/domain/src/status-page.ts, packages/domain/src/status-page.test.ts, packages/domain/package.json
Adds status-page types and schemas, snapshot and overlay rules, component status and freshness calculations, uptime-bar helpers, storage keys, JSON decoders, and domain tests.
Status-page and daily uptime persistence packages/db/src/tables/status-pages.ts, packages/db/src/tables/uptime.ts, packages/db/src/tables/index.ts, packages/db/drizzle/20261029111817_status_pages/*, packages/db/drizzle/20261030192851_merge_status_pages/*
Adds status-page and per-day uptime tables, their indexes and foreign keys, migrations and schema snapshots, and database table registry entries.
Page revisions and organization cleanup packages/backend/src/services/status-pages/outbox.ts, packages/backend/src/services/org/OrganizationService.ts
Adds helpers to increment page revisions and queue page, organization, or slug cleanup records. Organization purges queue page removals before deleting scoped rows.
Daily aggregation and monitor updates packages/backend/src/services/uptime/uptime-daily.ts, packages/backend/src/services/uptime/UptimeMonitorsService.ts, packages/backend/src/services/uptime/UptimeAlertSource.ts, packages/backend/src/services/uptime/*.test.ts, packages/backend/src/services/alerts/AlertsService.uptime.test.ts
Counts applied checks by UTC day and updates page revisions when monitor status changes. Monitor pause, resume, deletion, heartbeat, and overdue-heartbeat flows update the relevant page revisions and daily totals. Tests cover these updates and repeated reports.

Merge Risk: Minimal · up to df704
This change adds the status-page tables, shared snapshot contract and daily uptime counters, and no actionable merge-blocking issue remains. Existing uptime behavior is preserved, and the counters and page revisions are written inside the same transactions as the state updates.

- Around line 361-368: Update OrganizationService.purgeOrgScopedRows to run
queueOrgPageRemovals and all deletions from ORG_SCOPED_TABLES and
APPROVED_ORG_SCOPED_TABLES within one database transaction. Ensure any failure
rolls back both the cleanup queue insertion and the organization-row deletions.
Review comments at @packages/domain/src/status-page.ts:
- Around line 354-378: Update pageFreshness to use the publisher heartbeat
timestamp, not snapshot.generatedAt, when determining freshness; for monitored
pages, require both the heartbeat and probesSeenAt timestamps to be recent,
treating a missing probe timestamp as stale.

Status pages, components, incidents and their updates in Postgres, with a
revision outbox the publisher will drain. The snapshot schema and the pure
rules (component status, bars, freshness, break-glass overlay) live in
@maple/domain/status-page so the edge Worker can share them.
Uptime results now fold into per-day counters (uptime_monitor_daily) in the
same transaction as the state write, and a status flip bumps every page
showing that monitor.
