Converts the app from 'dashboard you visit' to 'system that finds you.'
Critical for the phone-first staffing shop that won't open a URL —
the system reaches out when something matters.
Daemon:
- Starts once per Bun process (guarded via globalThis sentinel)
- Default interval 15 min (configurable, min 1, max 1440)
- On each cycle, buildDigest() compares current state against prior
snapshot persisted in mcp-server/data/notification_state.json
- Events detected:
- risk_escalation: role moved to tight or critical (was ok/watch)
- deadline_approaching: staffing window falls within warn window
(default 7 days) AND deadline date differs from prior
- memory_growth: playbook_memory entries grew by >= 5 since last run
Channels (all opt-out individually via config):
- console: always on, logged to journalctl -u lakehouse-agent
- file: always on, appends JSONL to mcp-server/data/notifications.jsonl
- webhook: optional, POSTs {text, digest} to configured URL
(Slack incoming-webhook / Discord webhook / any custom endpoint)
Digest format (human-readable, fits in a Slack message):
LAKEHOUSE DIGEST — 2026-04-20 23:24
3 staffing deadlines within window:
• Production Worker — 2d to 2026-04-23 · demand 724
• Maintenance Tech — 4d to 2026-04-25 · demand 32
• Electrician — 5d to 2026-04-26 · demand 34
+779 new playbooks (total 779, 2204 endorsed names)
snapshot: 0 critical · 0 tight · $275,599,326 pipeline
/alerts page:
- Current status table (daemon state, interval, webhook, last run)
- Config form: enable toggle, interval, deadline warn window, webhook
URL + label (saved to data/notification_config.json)
- 'Fire a test digest now' button — force a cycle without waiting
- Recent digests panel shows the last 10 dispatches with full text
End-to-end verified live:
- Daemon armed successfully on startup
- First-run digest dispatched to console + file in <1s
- Events detected correctly: 3 deadlines within 7 days from real
Chicago permit data; 779 playbook entries surfaced as memory growth
- Digest text format is Slack-pastable
- Dispatch records appear in /alerts recent list
TDZ caveat: startAlertsDaemon() invocation moved to end of module so
all const/let in the alerts block evaluate before daemon reads them.
