Deny workspace warnings and lint suppressions, consolidate Rust and Python coverage under cargo xtask test with 60-second per-test limits, and remove stale flaky, stateful, Docker, and orphaned test artifacts.
Replace the eventfd/ring job bootstrap with one inherited arena descriptor, actor-owned sessions, sealed blob leases, awaitable inbox wakeups, and zero-copy Python mappings. Route VastAI mock provisioning through image-backed local Docker workers and preserve pinned child and controller routes across directory updates.
Add TOML job-file submission to the Fleet UI with generic started, running, and completed feedback, reusable remote job controller routing, cancellation and kill invariants, Tinygrad fixture and image support, and comprehensive Rust, Python, CUDA, and lifecycle-ordering coverage.
Add actor-backed manual node provisioning, control-plane endpoints, and fleet UI assets with durable provider lifecycle handling.
Simplify Myelin orchestration, node runtime, staging, and telemetry paths while removing obsolete engine-builder, dashboard-view, and local-mock implementations.
Align runtime delivery, data-plane, distribution, job-runner, process, telemetry, dashboard, Vast.ai integrations, and their tests with the revised actor and transport contracts.
Core no longer owns or drives OS threads. The runtime is now a single
tick-driven worker whose loop an external engine hosts and advances.
This is the cutover required before the engine seam is introduced.
Removed from core:
- Runtime::run() and its owned thread pool (spawn, park/unpark, join)
- notify_worker() and worker_threads: Vec<OnceLock<Thread>> plumbing
- Placement load-aware selector and its WorkerStats-driven next_worker()
- WorkerId newtype and the address->worker routing map; AddressMap is
now a plain AddrSet membership set
- num_threads from RuntimeConfig
Rewired for the single-worker tick API:
- python/wasm bindings, dashboard dummy node (deleted), myelin vastai
adapter, and the runtime/test suites
Cleanup folded in during review:
- prune three never-written WorkerStats counters (cross_sends,
messages_dropped, restarts)
- collapse the redundant tick_all params onto the WorkerContext handle

Add a RuntimeAdmin control plane for out-of-band inspection and mutation of live actors, bypassing their normal message handlers.
- src/admin.rs: add RuntimeAdmin + Admin<T> reply handle, the AdminCommand enum (ListActors, InspectActor, GetActorState, ReplaceActorState, StopActor, SuspendActor, ResumeActor), typed result types (ActorSummary/ActorStatus/ActorStateSnapshot/ListActorsResponse), and AdminError (ActorNotFound/AddressMismatch/TypeMismatch/Timeout)
- src/actor.rs: expose type-erased accessors on AnyActor — metadata() returning ActorTypeMetadata plus as_any()/as_any_mut() for downcasting — and Actor::inner()/replace_inner() so admin can snapshot or swap concrete actor state
- src/runtime.rs: wire a per-worker admin channel (admin_txs), expose Runtime::admin(), and implement the RuntimeAdmin ops that resolve an address to its owning worker, send the command, notify that worker, and return an Admin<T> handle; Admin::recv_ticking drives ticks and collects the reply
- src/worker.rs: add an admin_rx receiver and a drain_admin tick phase run before actor handlers, plus ActorPool helpers (actor_summary, get_actor_erased[_mut], suspend/resume/stop_actor_admin) that apply commands on the worker thread; fold admin_rx into the fast-idle has_work/tick_once checks
- tests/runtime_admin.rs: add 608 lines of end-to-end coverage for list/inspect/get/replace/stop/suspend/resume and the type-mismatch and not-found error paths
