 - **Occupancy support is incomplete relative to the spec.** Codex active-session discovery and opencode's server/SSE plus fallback path are not implemented.
 - **Authorization is only partially enforced.** HTTP method restrictions exist, but handlers do not consistently call `AuthorizeEvent`; an absent surface defaults to full-control Web.
 
+The first pass closed the store/API defects (lifecycle defaults, CAS content verification, validated replay, snapshot loading, and projection of task metadata) and added optional Gitea webhook/poll wiring. The remaining server-side gaps are below.
+
+### Remaining server-side gaps
+
+- **The orchestration coordinator is still absent.** A `TaskLeased` event only changes the projection. The server does not resolve a worktree, invoke `herdr.Adapter.Lease`, bootstrap the session, or translate adapter/session failures into lifecycle events. There is no durable session/lease-to-pane mapping.
+- **Rotation is still absent.** No adapter turn-boundary callback, occupancy trigger, milestone/thrash trigger, handoff save/validate flow, split-then-close sequence, or lease transfer coordinator is wired into the server. The existing occupancy readers and anchor validator are standalone library primitives.
+- **Harness discovery and registration are not operational.** Static herdr configuration and socket clients exist, but startup does not create adapters, ping configured herdrs, discover active Codex sessions, subscribe to opencode SSE, or run the required fallback/TTL monitoring loop.
+- **Provider ingestion is only partially wired.** Gitea is available when its environment is configured, but JSONL watching is not started by `main.go`; there is no provider lifecycle management, cancellation, or error health projection. Gitea terminal-state reflection and provider fan-out are not connected to server routes or background workers.
+- **Lifecycle event contracts remain incomplete.** Validation does not enforce the spec's `expected_version`, `ttl`, `anchor_sha`, `receipt`, or optional `handoff_ref` relationships, and the HTTP API does not validate actor/surface authorization at the event construction site. Completion without a report currently creates a generated placeholder artifact rather than requiring the stop-hook/wrapper receipt described by the spec.
+- **Quota and standup scheduling are not implemented.** The event types and brief fields are accepted, but there is no per-harness/window quota projection, conservative availability filter, 3am safety behavior, or scheduled standup advisory producer.
+- **Brief delivery and provider reflection are not implemented.** `/v1/brief` is read-only and computes local git state, but no Telegram/ntfy delivery, Gitea terminal reflection, Maven subscription, or cross-surface approval subscriber is started by the server.
+- **Federated worker behavior is not complete.** Machine affinity filtering is implemented, but there is no worker registration/heartbeat protocol, remote event transport, cross-machine worktree coordination, or server-side synchronization status beyond local git inspection.
+- **The server API is narrower than the spec.** There are no explicit task amendment/report/handoff upload endpoints, event subscription/streaming endpoint, health/readiness detail for providers and herdrs, or administrative endpoints for project/machine/herdr status.
+
 Recommended order:
 
-1. Fix lifecycle payloads and add endpoint tests.
-2. Add the orchestration coordinator: lease → worktree → harness session → bootstrap → lifecycle events.
-3. Implement rotation and turn-boundary monitoring.
-4. Wire provider webhook and polling integrations.
-5. Harden replay and CAS verification.
-6. Reconcile the status/checklist sections below with the actual implementation.
+1. Add the orchestration coordinator: lease → worktree → harness session → bootstrap → lifecycle events.

+3. Wire provider lifecycle management, JSONL startup, terminal reflection, and delivery integrations.
+4. Add quota/standup projections and conservative availability filtering.
+5. Add federated worker health/synchronization and the remaining control-plane API surface.
+6. Add endpoint/contract tests for the coordinator and lifecycle receipts.

 ## Important limitations
 
-- This is still a Layer 1 prototype. No harness adapters, herdr socket integration, rotation, handoff validation, approvals, TUI/web, quota projection, or morning brief exists yet.
+- This is still a Layer 1/2 prototype. Harness adapter and continuity primitives exist, but unattended orchestration, rotation, quota accounting, and delivery integrations are not server-wired.
 - Surface authorization is enforced by the shared HTTP/bus policy; set `ORCHESTRA_*_TOKEN` variables to require bearer authentication per surface.
 - Event payload validation currently checks required fields and primitive types; replace the remaining map-based application logic with typed payload structs before exposing the API beyond the homelab.
 - Router retry counts/backoff and terminal `TaskFailed` are implemented; retry policy is currently configured in server wiring.
