Rate-limit actor census and activity telemetry while preserving immediate lifecycle transitions. Route managed-process output into Fleet node tails, bound explorer retention, aggregate SWIM probes, and make sampler health transition-based. Restore stable explorer synchronization and refine Fleet bulk controls.
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.
The crate is the per-node metrics/logging pipe with a universal
subscriber endpoint, but "datastream" kept getting misread as a general
messaging plane. Rename crate, module paths, and public API
(`DatastreamEndpoint` → `TelemetryEndpoint`, etc.) so misuse is visible
on sight.
Renamed contracts (all in-repo producers/consumers migrated):
- env vars `MYELIN_DATASTREAM_*` → `MYELIN_TELEMETRY_*`
- artifact `datastream.ndjson` → `telemetry.ndjson`
- actor names `telemetry-publisher` / `telemetry-sink`
- wire ALPN `swactor/telemetry/0`
- `DATASTREAM_SPEC.md` → `TELEMETRY_SPEC.md`
Also fixes two latent test breaks: `process` and `iroh-driver` tests
imported `DatastreamEvent` from the crate root, which was never
re-exported; they now use the observer path `telemetry::frame::`.
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

Remove the datastore crate, the top-level design/orchestration/ring specs, the
benches, and the ci config. Add the dashboard host telemetry sampler
(cpu/disk/net/gpu/mem). Localize the pipeline-parallel e2e stub/mock paths.

Strip the collector/aggregator/postproc/snapshot, vastai sampler+shipper,
host/iroh/subprocess/swim introspection, relay observability, sink/spool, and the diag
binaries; drop the t_diag_* tests. Remove DiagEvent emission from iroh_driver. Add
datastream emit/wire (mux + NoopSink/UdpFrameSink/ClusterFrameSink) and rewire the
dashboard onto datastream_source.
