Land the first working two-stage pipeline-parallel run over VastAI, wiring a real inter-stage data path with observability, a max-price offer cap, and remote-image reuse.
- orchestrator_app: raise the VastAI pipeline-stage cap from 1 to 2 and let VastAI pipeline planning resolve the HuggingFace GGUF from the default local cached-model metadata path instead of requiring host mounts; add --vastai-max-dph-total (CLI/env/TOML) config.
- vastai_provisioning: make complete_bootstrap a no-op so the SSH bootstrap log tail stays alive past runtime-ready until node stop, preserving post-ready worker logs; add a test asserting the tail is only stopped on NodeStop.
- worker_node: emit data-path NodeEvents across the pipeline (iroh_edge_stream_arrived/bytes_read/bytes_sent, egress_ring_read, ingress_ring_write) with edge/byte metadata.
- tools/vastai: add max_dph_total (PP_MAX_DPH_TOTAL) to SelectionPolicy, the reachable-offer filter, and the search query, and improve the empty-pool error message.
- xtask: pass --skip-rebuild for the VastAI scenario and gate it on a new require_vastai_data_path_facts plus GPU facts (ring install, activation object load/step, interstage handoff, iroh edge read/sent).
- mvp_chat: add ChatModelConfig (model id/gguf/tokenizer/max-context) forwarded to the orchestrator; for VastAI + skip-rebuild, emit skip events and reuse the remote node image without a local build.

Replace the driver/session/action/event abstraction with a single OS-process supervisor thread and a minimal lifecycle-only public API.
- supervisor: add a dedicated swactor-process-supervisor thread that owns the child, runs it with null stdio, wakes via an eventfd plus poll(2), reaps with waitpid(WNOHANG), and escalates SIGTERM to SIGKILL after a deadline, reporting only lifecycle ThreadEvents over a SegQueue plus wake channel
- actor: collapse ProcessActor<D> into a non-generic state machine (Spawning/Running/Stopping/Done) that owns the supervisor handle, drains events on SupervisorWake, forwards lifecycle as ProcessOutput, and triggers shutdown_now in on_stop
- lifecycle: add ProcessOutputConfig (Disabled/DatastreamMirror) with a JSON proc.<label>.lifecycle mirror (schema swactor_process.lifecycle.v1), command-basename label derivation/sanitization, and an RAII reservation registry preventing duplicate channels
- message/types/spawn/lib: trim the API — ProcessCommand is now only Stop { kill_after }, ProcessOutput covers Started/SpawnFailed/Exited/Error, ProcessSpec keeps command/args/env/working_dir/label; re-export spawn_local_process/send_process_command and drop the custom-driver spawn_process
- removed: delete the action/event/local/mock/session modules and the ProcessDriver/ProcessWaker/EventQueue/PtySize/ProcessMode types plus the old test suite (actor_scenarios, e2e_process, local_driver, proptest_session, session_scenarios); add public_api_stage1/2 tests and the SWACTOR_MANAGED_PROCESS_SPEC.md
- swactor core: demote ProcessOutputObserver to a legacy/custom adapter (no longer auto-attached), remove Runtime::set_process_output_observer and Ctx::process_output_observer, and add the datastream dependency to the process crate for the mirror

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

Extract the timer wheel and watch registry from the worker into a reusable std-extension crate, generalize the worker around a RuntimeExtension factory, and decompose the monolithic runtime test file into focused suites.
- crates/std: extract TimerWheel (deterministic tick-counted one-shot/interval timers) and WatchRegistry (target-to-watcher death-notification index) out of src/worker.rs into reusable modules
- crates/std: add Ctx extension traits (CtxMonitoring, CtxNaming, CtxWatching, CtxTimers) and Runtime extension traits (RuntimeNaming, RuntimeWatching, RuntimeGroups) wiring monitor/name/watch/timer/group support
- src/worker.rs: replace the hard-coded timer/watch fields with a generic RuntimeExtension factory and add route_to_pool_or_remote for message routing (local pool, then cross-worker address map, then external inboxes)
- tests: split the 4622-line tests/runtime_api.rs into focused suites (actor_lifecycle, message_delivery, runtime_stress, std_extension) plus a shared tests/common/mod.rs harness, and drop watch_api.rs
- benches/fuzz: add runtime_benchmarks and adjust the runtime fuzz target
- tools/docs: add fn_complexity.py and loc_analysis.py analysis scripts and refresh the runtime and worker-thread docs

Lay down the wasm-actor host, a frontend-agnostic command layer, and a
distribution registry.
- command (new crate): CommandRouter dispatching to built-in inspection handlers
(overview/workers/actors) plus user-registered handlers, with line and
query-param parsers; built for REPL/REST/TUI/WebSocket frontends.
- wasm-actor (new crate): skeleton host — WasmActor, Builder, Engine, error
types — with echo/double/silent guest fixtures and integration tests.
- distribution: add Registry (member catalog + lookups) and Snapshot, with tests.
- core: extend the worker watch API; add watch_api integration tests.

Make mailbox push infallible and replace the locked tick-timing buffer with a
lock-free ring.
- channel: HybridChannel::push and Sender::send now return () — overflow always
absorbs, never rejects — dropping the Result<(), T> surface and its callers.
- stats: tick_timings moves from Mutex<VecDeque> to a lock-free crossbeam
ArrayQueue (drop-oldest-on-full), removing the per-tick lock.
- ripple the signature change through worker/runtime/config; drop worker_benchmarks.
- expand runtime_api tests around the new channel/stats shapes.

Split the monolithic crate into a Cargo workspace with the Python and Wasm bindings as separate member crates.
- Cargo.toml: declare a `[workspace]` with members `.`/`crates/swactor-python`/`crates/swactor-wasm`, remove the `python` feature and pyo3 dependency, and change root crate-type from `["cdylib","rlib"]` to `["rlib"]`
- crates/swactor-python: new cdylib crate re-exporting the PyO3 bindings (Runtime/RuntimeConfig/RuntimeHandle/Inbox/Ctx/ActorAddress/RuntimeStats), depending on `swactor` + pyo3; pyproject.toml and uv.lock relocated here from the root
- crates/swactor-wasm: new cdylib crate moved from top-level `wasm/`, depending on `swactor` with `no_random` features
- src/actor.rs: widen `Actor::new`, `AnyActor`, `ContextInner`, and `Ctx::raw_inner` to `pub` so the separate binding crates can drive the runtime
- src/lib.rs: delete the in-tree `python` module and `#[pymodule]`, and gate the `no_random` RNG behind `all(feature = "no_random", not(feature = "getrandom"))`
- tools/: relocate package.json/package-lock.json; drop the now-duplicate `wasm/Cargo.lock`

Adds some basic benchmarking, stress tests. They still need to be properly examined to ensure they are testing the correct properties, but fit for "good enough". Implements the HybridChannel type, which features a channel buffer that can withstand overflows. It does so by providing a dequeue behind a mutex. Without overflow, will push messages into the lock free ArrayQueue implemented by crossbeam_queue; when that buffer fills, will use the locking portion provided by the Mutex<VecDequeue>.
In the future we can even further optimize this, perhaps with some linked list implementations of lock-free channels, but, like the benchmarks, this fits the "good enough" bar for now.
