 ## Status
 
-Not started, Phase 0 partially unblocked. **5 decisions block Phase 1** — see [00-decisions.md](00-decisions.md).
+Mock API layer implemented. Remaining: wire page components to fetch from it, RED specs, REFACTOR passes — see [INDEX.md](INDEX.md).
 
 ## Task board
 
 Task board lives in [INDEX.md](INDEX.md) — one row per task, one file per task (`<id>-<slug>.md`), agent-harness format. That file is the source of truth for execution order; this README is a human overview only.
 
-| Phase | Est. |
-|---|---|
-| 0 — unblock deployment | — |
-| 1 — atlas core (RBAC, informers, redaction) | ~4d |
-| 2 — Surface B: cluster topology | ~3d |
-| 3 — Surface E: delivery tree | ~3d |
-| 4 — Surface C: terminal | ~2d |
-| 5 — Surface D: chat + rate limiter | ~5d |
+Everything cluster/backend/infra (GitOps, DNS, RBAC, the real `atlas` Go service, rate-limiting tiers 1-3, observability) is out of scope for this repo — see [REQUIREMENTS.md](REQUIREMENTS.md), a handoff spec for whoever builds that separately.

 ## Rules carried from the ADR
 
-- I1: `riotpiao.com` is the only public hostname, ever
-- I2: browser never talks to an internal API directly — atlas is the only origin
-- I3: redaction is allowlist-only, enforced by DTO construction
-- I4: no free-form string reaches an internal system (closed enum, snapshot-membership validation)
-- I5: GPU chat concurrency capped at 6 of 8 sequence slots, disconnect cancels upstream immediately
+- I2: browser never talks to an internal API directly — all cluster data flows through this app's own `/api/*` routes
+- I3: redaction is allowlist-only — the mock fixture already excludes denied fields, keep it that way
 - TDD: RED (tests named before code) → GREEN (minimal code) → REFACTOR, per phase
 - Playwright e2e is a hard requirement for every UI-shipping phase (2, 3, 4, 5) — no surface merges without a passing spec
