The datastream is metrics/logging only; control decisions must never branch
on a frame. This was a recurring cultural problem with no structural
enforcement. This change makes it a compile-time and CI-enforced fact.
datastream crate (lib.rs):
- Stop re-exporting Frame, DatastreamEvent, FrameDelivery at crate root.
is now a compile error (E0425). These types live
only in datastream::frame::* and are documented as the observer surface.
- Safe identity types (ChannelId, StreamId, Position, Record, etc.) remain
re-exported at root for producer-side callers.
orchestration/app.rs:
- Extracted all frame-touching code (CollectedDatastreamFrame,
drain_datastream_connections, update_load_progress_from_frame,
drain_frames, archive_collected_frame, pump, OrchDatastream,
DashboardSupport) into two new observability modules:
frame_collector.rs and orch_datastream.rs.
- The orchestrator now interacts through a FrameCollector whose
drain/drain_with_progress methods take closures; it never names Frame,
DatastreamEvent, or CollectedDatastreamFrame.
- StageLoadProgress (the one control-relevant signal previously scraped
from frame payloads) is extracted inside FrameCollector and handed to
the control loop as plain data.
xtask:
- New check-telemetry-isolation command scans control-plane modules
(orchestration/, distribution/, data-plane/, provisioning/) for
forbidden frame-type references and fails the build if any are found.
Verified: workspace builds (myelin + dashboard feature), datastream 29
tests pass, myelin 64 lib tests pass, check-telemetry-isolation passes
clean.

Add read-only actor overview and per-actor dossier pages to the dashboard, fed by enriched per-actor runtime snapshots.
- `dashboard/swactor/actor_view`: new `ActorPanelView`, a tolerant frame consumer over `runtime.actors`/`runtime.stats` that folds per-actor snapshots and serves `/view/swactor/actor-overview` (roster) and `/view/swactor/actor-dossier` (per-actor detail), each backed by an embedded HTML template (`actor_overview.html`, `actor_dossier.html`)
- `dashboard`: register both views in `DashboardHandle` and export `actor_overview_view()`/`actor_dossier_view()` from the swactor module
- `swactor` core: enrich `ActorSnapshot` with `actor_type` and `message_type` (populated from `slot.actor.metadata()` in `ActorPool`) and add `ActorAddress::to_full_hex()` for untruncated display
- `myelin/orchestration`: publish actor stats to the dashboard via a `runtime.actors` channel producer (`stats_hook_on`) threaded through the distribution stack, and carry the orchestrator actor address into readiness signaling
- workspace `Cargo.toml`: add `default-members` for native iteration and a centralized `[workspace.dependencies] tokio` so members share one feature set; `dashboard/Cargo.toml` switches to `tokio.workspace = true`

Trim the datastream crate to its dumb-pipe core: drop the frame-timing sidecar, make mux positions gap-free for accepted frames, and simplify the endpoint fanout.
- mux: defer position assignment from submit to drain so an overflowed submission no longer consumes a position (no synthetic gaps); submit now returns bool and the Mutex<Receiver> is removed since positions are assigned only to accepted frames
- endpoint/mux: switch from std::sync::mpsc to crossbeam-channel and drop per-event event_matches_request filtering — request filters now apply only to the initial catalog snapshot, and future events broadcast to all subscribers
- endpoint (DeliveryFanout): snapshot sender handles under the lock and deliver outside it via FanoutTarget/FanoutReport, so large batches or slow subscribers no longer block subscribe/snapshot control-plane ops
- emit/endpoint/producer: drop set_frame_timing_enabled/frame_timing_enabled and the Position return from submit_record/submit_text/submit_bytes, and add submit_text_owned taking owned String
- timing/lib/spec: delete the timing module and FRAME_TIME_CHANNEL/FRAME_TIME_CHANNEL_ID/FrameTimeSample re-exports (including the auto-registered timing channel in ChannelCatalogState) and renumber the DATASTREAM_SPEC.md section references across frame/ingest/store/mux
- tests: remove the 567-line shared datastream_support/mod.rs harness

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.

SwimTelemetry observer records probe RTTs (p50), recent targets, and membership
transitions for the node's telemetry tick. Expand registry/registry_actor, datastream
catalog/emit/source, and the pipeline-parallel cluster/fleet. Wire the node main loop
to emit host/runtime/transport/membership frames.

Promote pipeline-parallel-inference to a first-class app and consolidate observability on the datastream wire, decoupling the dashboard crate from `distribution`.
- apps/pipeline-parallel-inference: move the example out of `examples/` into `apps/` as its own workspace, rename binaries to `pp-worker`/`pp-orchestrator`, and strip release binaries
- cluster: add `ClusterNode`, a synchronous facade over the actorized distribution protocol (IrohDriver + per-node Runtime hosting Swim/Registry/Metadata/Directory actors with a `MembershipFanout`), replacing ad-hoc `driver.node()`/`tick()` call sites
- fleet: add per-node fleet telemetry that ships identity/resource records as `DatastreamFrame`s over the cluster transport to the orchestrator's `DatastreamSink`, folded into a `FleetView` on a 3s tick
- provision: add best-effort, opt-in SSH boot-phase telemetry (`PP_DEPLOY_KEY`) that streams rented-node boot logs onto the orchestrator's datastream as `proc.boot.<stage>.*`
- dashboard: rewire the crate dependency from `distribution` to `datastream`, drop the standalone `swactor-datastream-dashboard` binary, and rewrite `datastream_source.rs` to demux per-node frames into Overview/Distribution/Fleet views with live-node TTL filtering
- distribution: refresh dist/netmap plugin copy and README from "Kademlia routing" to gossip-directory terminology
