Backend discipline. Observability, failure buckets, treasury, status — the kingdom's machine room. Most of these you should never see.
The Foundation
Auth, schema, RLS posture. The first stone of the kingdom.
The Gate
Email magic-link auth + COPPA-aware DOB capture for minors.
The Compass
Server-side analytics — typed event union, PostHog backbone.
The Chorus
Parent consent flow for minors. COPPA-clean teacher access.
The Vault
Founder-only ops dashboard. Revenue, cohorts, recent incidents.
The Beacon
/api/health endpoint + Watchtower probe scaffolding.
The Watchtower
Bucketed failure detection across Anthropic / Stripe / Resend / Supabase / Redis / ElevenLabs.
The Scheduler
Cron infrastructure with CRON_SECRET auth + telemetry envelope.
The Ledger (Catalyst)
/vault/catalyst — founder ops surface for the viral loop.
The Treasury
Provider runway dashboard. Anthropic + ElevenLabs + Stripe MRR snapshots.
The Beacon
Public status page driven off Watchtower. All 6 services + bucketed failure codes.
The Sentinel
Founder daily ops digest email. /api/cron/sentinel-daily runs 12:00 UTC (7am Central) sending to FOUNDER_EMAILS allowlist: yesterday's signups, takes, advance verdicts, paid conversions, active trial count by expiration bucket, failed crons by name, provider error counts. One read replaces logging into 4 dashboards. Compounds Mark XXVI Watchtower + Mark XXI Vault + Mark XLV Treasury for daily push instead of pull.
The Treasury Atlas
Founder-only weekly trends page at /vault/trends. 7-day-over-7-day deltas across signups, judge takes, advance verdicts, paid conversions. Tone-mapped (emerald positive, rose negative). Pull surface — visit when you want trend context wider than the Sentinel daily push. requireFounder gated. Fail-soft Promise.all so any single failed query returns sensible empty defaults. Companion-surface links to /vault, /vault/catalyst, /status.
The Manifest Wider
Three new public JSON catalog endpoints sister to Mark LXVIII Manifest (/api/marks): /api/composers exposes the composer aggregator + excerpt counts + instrument coverage, /api/glossary exposes every term grouped by section with the OG-aware url field, /api/states exposes every typed state audition system with tiers + window + repertoire signal + search terms. CORS-open, hour-cached, ISR-revalidated. Why expose: MCP servers / Claude Skills can now answer 'what does the FMEA want' or 'what Bach excerpts are calibrated' or 'what does spiccato mean' programmatically without scraping our pages. Closes the catalog-as-API gap.
