feat(engine): substrate-neutral execution engine abstraction 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. 2026-08-10 20:23:03 +00:00			`[package]`

feat(myelin): enforce actor-owned control flow Architecture enforcement: - Install a repository-owned rustc wrapper for ordinary cargo check, build, and test commands. Resolve compiler item identities so renamed imports and helper wrappers cannot hide spawning, timing, blocking, polling, thread, or runtime-driving capabilities. - Define the execution-owner crates and reject dependencies from those substrates back into Myelin policy. Add compile-pass and compile-fail contracts for actor helpers, execution owners, test waits, forbidden capabilities, suppression attempts, and owner dependency inversions. Execution ownership: - Add engine-owned actor timers with cancellation and generation identity, then migrate lifecycle deadlines and protocol ticks off application tasks. Keep networking, process output, telemetry, and blocking provider calls in their approved I/O substrates. - Move process spawn, wait, signal, Unix listener, and output-following mechanics into swactor-process. Isolate Vast.ai blocking HTTP mechanics behind its adapter while actors retain retry, recovery, and provisioning decisions. Myelin control flow: - Rework manual control, worker lifecycle, provisioning, provider recovery, job deployment, distribution, edge orchestration, and shutdown as actor state transitions and typed effects. Preserve durable provider adoption and command outcomes across graceful and abrupt restarts. - Replace controller loops and timer-forwarding tasks with actor messages; leave substrate tasks as cancellable observation streams with no durable policy state. Properties and resource ownership: - Add deterministic engine and component properties, a stateful mock-VastAI lifecycle model, persisted regression cases, controlled fault injection, and a bounded nightly workflow covering restart and teardown behavior. - Terminate reply observers, cancel telemetry collectors, bound dashboard projections, and release child observers, file descriptors, process records, and inode-verified Unix sockets on every terminal path. Verified with the compiler-policy contracts, 105 Myelin library tests, 32 swactor-process tests, telemetry cancellation contracts, randomized stateful restart cases, cargo check, and formatting checks. 2026-08-19 21:38:14 +00:00
