 `go test ./...` passes, but the implementation is still a tested substrate/router prototype rather than a functioning unattended multi-harness orchestra. The following gaps were verified against `orchestra-spec (1).md` and the current code:
 
-- **Harness execution is only partially wired.** `internal/orchestrator` now provides lease → worktree → adapter session → optional bootstrap coordination, but `main.go` does not yet construct concrete worktree/adapter registries or run monitoring callbacks.
+- **Harness execution is wired for configured Git/Codex deployments.** The router invokes the coordinator; `ORCHESTRA_REPO` + `ORCHESTRA_WORKTREE_ROOT` enable Git worktree creation, configured herdr socket adapters, session creation, and optional bootstrap. Other harness types and monitoring callbacks remain pending.
 - **Rotation is not implemented.** There is no turn-boundary callback, herdr event subscription, occupancy-triggered rotation, milestone/thrash trigger, or split-then-close coordinator.
 - **Lifecycle API payloads are invalid.** The release, complete, and block endpoints all emit `{"source":"api"}`, while validation requires `handoff_ref` or `reason`, `report_ref`, and `blocker` respectively. The documented lifecycle endpoints therefore cannot complete successfully.
 - **Provider integrations are partially wired.** JSONL watching and optional Gitea webhook/poll loops now start from environment configuration, but terminal reflection, provider health, cancellation, and delivery fan-out remain absent.

 ### Remaining server-side gaps
 
-- **The orchestration coordinator is not fully operational.** A reusable coordinator now resolves a worktree, invokes `herdr.Adapter.Lease`, bootstraps handoffs, and blocks failed starts. It is not yet constructed from deployment configuration, persisted, or connected to turn/lifecycle monitoring in `main.go`.
+- **The orchestration coordinator is operational but incomplete.** It is constructed from deployment configuration, resolves a worktree, invokes `herdr.Adapter.Lease`, bootstraps handoffs, and blocks failed starts. Session mappings are in-memory and turn/lifecycle monitoring is still pending.
 - **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.** JSONL and Gitea are available when configured, but there is no provider lifecycle management, cancellation, error health projection, terminal-state reflection, or provider fan-out.
