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.

Introduce the swactor engine: a swactor-owned composite that retains a
selected execution substrate, drives the core runtime, and hosts the
async/blocking/timer work that backs actors. Integrations receive one
cloneable EngineHandle and never construct or borrow a raw Tokio
runtime/handle.
Engine crate (crates/engine):
- The contract: spawn / spawn_blocking / timer / interval / now, a
per-implementation capability model with construction-time binding
(require()), and engine-owned time. The engine owns all progression;
actor handlers stay synchronous and never .await.
- TokioBackend owns the Tokio runtime and schedules core ticks and
supporting futures on it; SteppingBackend is a single-threaded
deterministic scheduler with virtual time (the non-Tokio portability
proof). Core is driven through its existing tick() surface; a
self-rescheduling CoreDriver is installed at construction and is the
sole place permitted to call try_tick.
iroh-driver:
- Receives an EngineHandle instead of a raw Tokio Handle. Accepts,
reads, dials, writes, endpoint construction, and teardown schedule
through it; required capabilities (tasks/timers/io) are validated
before the endpoint binds. Engine-hosted interval pumps drive
actor-bridge, datastream, and edge ingress.
myelin:
- One node/orchestrator engine owns core, protocol tick injection, and
transport progression; the application loop only drains
integration-owned queues. Stage-shard process readers, delayed actor
messages, helper stdout/stderr, prompt RPC, and CPU sampling all
schedule through the engine (spawn_blocking / engine tasks / timers).
- Removed the split-engine APIs: install_actor_bridge_pump(period) and
spawn_protocol_ticker(period) use each component's stored engine;
deleted the no-op pump_network callback and its plumbing; deleted the
dashboard raw-Tokio/standalone-runtime conveniences.
Enforcement:
- A clippy disallowed-methods boundary forbids direct runtime/scheduling/
time/core-driving bypasses, denied in swactor-engine, iroh-driver, and
myelin. Retained excluded uses (VastAI provider, provider process
supervision/log capture, OS-signal/stdin/process-control sequencing)
carry narrow allowances with reasons.
Verification:
- Engine contract + unit tests (incl. the SteppingBackend portability
proof), iroh integration tests (capability rejection before binding,
multi-node actor behavior), and a production execution-composition
smoke test that observes engine-driven actor progress with no ambient
Tokio runtime and no manual tick/pump. Workspace all-target/all-feature
clippy and tests are green.
Specs co-located with their crates: ENGINE_SPEC.md in crates/engine,
IROH_DRIVER_SPEC.md in crates/iroh-driver. VastAI remains explicitly out
of scope pending its separate redesign.
Specs gain a monotonic Id and relocate by their true status: drafts
(WIP/aspirational) to docs/specs/drafts/, and accurate code-behavior
references stay in their crate dirs. docs/specs/archive/ is reserved for
superseded docs (currently empty).
Dispositions were cross-referenced against code, not the specs' own headers.
IROH_DRIVER claimed "current-state" but ~30% is unbuilt redesign, so it moves
to drafts. DATA_PLANE_ACTOR's central integration claim is unrealized (myelin
bypasses its node actor), and ACTOR_PANEL is not a reference; both are dropped
rather than reviewed or archived. DATASTREAM and MANAGED_PROCESS stay as
references; MYELIN stays in place (stale, flagged for review).
From here, commit titles reference a spec by [N] when one applies. This
bootstrap commit does not carry one.

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 project licensing and a full README, plus a minimal WebAssembly ping-pong example that exercises the actor runtime.
- `LICENSE`: add the full GNU AGPL-3.0 text and set `license = "AGPL-3.0-only"` on every package (`swactor`, each crate, `apps/myelin`, `tools/vastai`, `xtask`)
- `README.md`: rewrite from a stub into a full project overview, covering features (actor_id routing, WASM, iroh QUIC/SWIM, OTP-style std, process manager, zero-copy objects, datastream metrics, dashboard), architecture, examples, developing, status, and license
- `examples/ping-pong`: new standalone workspace (`pingpong` cdylib) where two actors volley on a single-threaded `wasm` runtime driven by a Node host via `tick()`, demonstrating spawning, message passing, and death monitoring (`watching`)
- `examples/ping-pong`: add a host/run harness -- `run.sh` (wasm-pack build + `run.mjs`), `serve.sh` (dashboard + static demo), `index.html`, and a pinned `Cargo.lock`
- `.gitignore`: stop ignoring `.loop/`, `.deployment-notes/`, and `.omp/`

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`

Promote the `mvp-system` workspace library crate to a standalone application at `apps/myelin`, rebranding the MVP system along with its binaries, node image, and spec.
- workspace `Cargo.toml`: swap member `crates/mvp-system` -> `apps/myelin` and drop `apps` from `exclude` so the app joins the workspace
- `apps/myelin/Cargo.toml`: declare package `myelin` with `autobins = false` and explicit `[[bin]]` targets `myelin-worker`, `myelin-orchestrator`, `myelin-chat`
- `apps/myelin/src`: move the whole `mvp-system` source tree and rebrand module surfaces (`chat/mod.rs`, `prompt/mod.rs`); add `bin/chat.rs` (`myelin::run_chat_from_args`) and delete the old `mvp_chat.rs`

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

- mvp_chat: add an interactive REPL client connecting to the prompt RPC port (default 127.0.0.1:19777)
- mvp_orch_one_node / mvp_one_node_chat: add the single-node orchestrator that provisions a `LocalDockerPlugin` node, loads `bartowski/Llama-3.2-1B-Instruct-GGUF` (Q4_K_M), and exposes the prompt RPC listener with boot/route/weight timeouts
- mvp_node: add the GPU worker binary that spawns `tinygrad_worker.py` (default device CUDA) and ships runtime telemetry via a `ClusterFrameSink`

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>.*`
