THE ALGO · ESTATE HUB

the watch layer · hub.thealgo.com v0.3.0 · wired to /api/health · 2026-08-01

Birth rules (CRITICAL-PATH v1.4.0 · LANE 7 §2): single health truth · records TRANSITIONS, not states ("green right now" is exactly what a starved warehouse looks like) · always shows last-transition time · fields print verbatim · the worker's shape IS the contract (R1) — this page composes nothing.

Lane	Door	State	Last OK	Last Transition · what changed	Fails	Note

Shape (worker v0.2.0, THE contract per R1):

GET /api/health → { truth, generated, doors: [ { door, lane,
    enabled, endpoint, state, last_ok, last_checked, consecutive_fails, note, last_transition_from,
    last_transition_to, last_transition_at, last_transition_note, what } ] }

— what is composed SERVER-SIDE; this page prints it verbatim.
D1 estate-health is the ledger; the cron writes a transitions row only when a door CHANGES state. Alerts (R2): worker POSTs →down/→degraded transitions to env.ALERT_WEBHOOK (secret binding, Justin's hand).
Auth: behind Kevin's KYC/login plan before go-live, never open. YouTube doors swap to /youtube/api/status post-P2 (pre-P4 sources flagged in probes/youtube.md). ◌ UNKNOWN = never checked or disabled (R3: unknown ≠ stale).
