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`
- `apps/myelin/node-image`: relocate the worker image assets from `apps/mvp-node/` (Dockerfile, Dockerfile.base, tinygrad_worker.py, entrypoint, e2e script) and rename `MVP_SYSTEM_SPEC.md` -> `MYELIN_SPEC.md`
- `xtask`: rewrite build/reference paths for the rename (~1000-line churn); add `crates/dashboard/ACTOR_PANEL_SPEC.md`

Consolidate the duplicated JSON codec into `transport` and relocate the iroh edge-transport pieces into `iroh-driver`, dissolving the `mvp-system` transport shim.
- `transport`: add a canonical `json_codec::JsonCodec<M>` (re-exported from the crate root) as the single JSON codec for serde message types
- `distribution`/`datastream`: drop the per-crate `JsonCodec` copies and the `impl_json_codec!` macro; register SWIM/gossip and publisher messages against the shared `swactor_transport::JsonCodec`
- `iroh-driver`: move `driver_pumps` and `endpoint_advertisement` out of `mvp-system/src/transport/`, re-exporting `EndpointAddrMask`/`advertised_endpoint`/`MVP_IROH_ENDPOINT_ADDR_MASK_ENV`, and relocate the endpoint guarantee test to `iroh-driver/tests/endpoint_advertisement.rs`
- `mvp-system`: delete the `transport/` module and keep codec aggregation in a new `codecs.rs` (`register_mvp_actor_codecs`)
- `mvp-system/node`: shrink `worker_node_runtime.rs` (~260 lines) by adopting the relocated modules and collapsing verbose `emit_stdio_node_event` calls into local `boot()`/`worker_evt()` closures

Replace the sprawl of narrow per-implementation test files (and the inline #[cfg(test)] modules embedded in source) with a small set of black-box behavior-guarantee suites keyed to the public modules, per the BEHAVIOR_GUARANTEES spec.
- tests/mod.rs: cut the test module list to local_e2e/node/observability/orchestration/prompt/staging/transport (+local_mock), removing bootstrap_datastream/relay_provisioning/run_plan/stage_controller/shard_*/weight_*/tx_rx_edge_actor/worker_edge_adapter/telemetry/shared_ring_helper_abi/orchestrator_run_fsm files
- add tests/orchestration_guarantees.rs (1074 lines) and staging_guarantees.rs (747) as black-box contract suites over the public RunPlan and StageController surfaces, referencing specs/BEHAVIOR_GUARANTEES.md
- add focused node_guarantees, prompt_guarantees, and transport_guarantees suites covering node-agent runtime-ready reporting, prompt defaults/terminality, and endpoint-advertisement relay masking
- rename local_mock_pipeline_integration to local_e2e_guarantees and observability_surface_guarantees to observability_guarantees
- strip the large inline #[cfg(test)] mod tests blocks from source files (orchestration/app.rs -3215, chat/runtime.rs -790, node/worker_node_runtime.rs -522, vastai/mod.rs, gguf_shard/shard_fetch, etc.) and the #[path]-registered shard_* test mods from lib.rs
- Cargo.toml: drop the harness=false mvp_chat_mock [[test]] target, and remove the python_worker_protocol integration test

Collapse mvp-system's public surface to three binary entrypoints and make every domain module private, deleting dead provider/worker/membership implementations and inlining provider config.
- lib.rs: expose only run_chat_from_args/run_orchestrator_from_args/run_worker_node_from_env (plus a crate-private in-process helper) and the cached-model consts, and demote chat/node/observability/orchestration/prompt/staging/transport to private mods
- orchestration/mod.rs: make app private, gate engine_builder behind cfg(test), drop docker_cluster from provider_adapters, tighten vastai to pub(super), and replace pub re-exports with pub(super) run_from_args/run_in_process_from_args
- orchestration/config.rs: inline VastAiConfig/ResolvedVastAiConfig/looks_remote_image (removing provider_adapters/vastai/config.rs) and drop the DEFAULT_PIPELINE_CACHED_MODEL_* consts (hoisted to lib.rs)
- orchestration/provider_adapters/vastai: delete the ProviderPlugin impl VastAiProviderPlugin and all client/bootstrap/config accessors; repoint call sites to crate-level #[path] mods for provisioning/node_provisioning/node_actor/gguf_shard/run_fsm/run_plan
- delete orchestration/{membership_readiness,token_endpoint,resource_inventory}, node/{boot_lifecycle,data_plane_bridge(-74)}, and the worker crate-internal modules (control/device_bridge/process_adapter) along with their guarantees tests
- chat/node: narrow node_image and worker_node_runtime to private and expose only pub(super) run_from_args / run_worker_node_from_env

Convert the remaining thread/mpsc-based provider monitor and stage-shard fetch loops into swactor actors, propagate worker-crash reasons through the actor message chain, and validate cached stage shards before reuse.
- orchestration/provider_adapters/vastai: replace the thread+AtomicBool VastAiProviderMonitor with VastAiProviderMonitorActor driven by Poll/Stop messages on its own RuntimeHandle (schedule_provider_monitor_poll), preserving the status/terminal-failure observation logic
- node/worker_node_runtime: convert the blocking stage-shard-fetch mpsc loop into StageShardFetchActor (Start/PollChild/ProcessLine/ReaderError/ReaderClosed via ExternalSender, on_stop kills and joins the child) reporting Progress/Done/Failed
- staging/gguf_shard: add validate_stage_shard_cache (tensor count/alignment/name/dims/type) and mix STAGE_SHARD_CACHE_FORMAT_VERSION into the shard_cache_key; materialize_stage_shard_with_process now validates a cached shard, emitting StageShardCacheInvalid and refetching when stale
- node/actor + orchestration/actor: NodeAgentMsg::WorkerCrashed now carries Option<reason>, surfaced as ObserveStageFault{reason}/StageFault{reason} up to the orchestrator; NodeAgentActor records last_worker_crash
- orchestration/app: complete_bootstrap now runs after runtime-ready without dropping stop handles (ProvisionedClusterGuard) and folds worker-crash reasons into stage-fault errors; chat/runtime adds cached-model config selection
- xtask: relax the data-path requirement to accept activation-step-executed OR downstream-activation-loaded

Promote the data-plane into its own crate with a swactor-facing DataPlaneNodeActor that owns wire-edge lifecycle, and move the edge/ring/egress/ingress machinery out of mvp-system into crates/data-plane.
- data-plane/src/actor.rs: add the 769-line DataPlaneNodeActor implementing ActorInterface, owning WireEdgeEndpoint provisioning and the EdgeEstablisher lifecycle and draining commands to arena/worker/transport actors (DataPlaneArenaMsg/WorkerMsg/TransportMsg) with DataPlaneReportMsg back to a report sink
- data-plane/src/lib.rs: expand the crate surface to expose actor, arena, edge_actor, edge_lifecycle, egress, and ingress alongside object_record/ring, and reframe it as actor-oriented wire-edge / ring / arena / object-movement contracts
- data-plane: move edge_actor and edge_lifecycle (from node/), egress (from worker/), and ingress (from node_data/) into the crate, and add ArenaSample (serde Record, ARENA_SAMPLE_CHANNEL/INTERVAL) to arena.rs
- data-plane: add DATA_PLANE_ACTOR_SPEC.md and the data_plane_actor_guarantees/edge_lifecycle_guarantees/egress_guarantees tests
- mvp-system/node: add data_plane_bridge.rs wiring the node runtime to the DataPlaneNodeActor, drop the old node_data/arena.rs and node_data/mod.rs (now in data-plane), and remove the arena_manager_guarantees test
- mvp-system: drop node_data from the lib.rs pub surface and repoint node/mod.rs to consume the data-plane crate

Reorganize crates/mvp-system from flat files into domain module trees (chat, node, node_data, observability, orchestration, prompt, staging, transport, worker) with documented mod.rs boundaries, and drop the stale inline spec docs.
- lib.rs: replace ~20 flat mod declarations with one pub-mod-per-domain (chat/node/node_data/observability/orchestration/prompt/staging/transport/worker)
- node/, chat/, observability/, orchestration/, staging/, prompt/, transport/, worker/: add mod.rs files with module-boundary doc comments and re-exports (e.g. chat re-exports run_from_args; orchestration re-exports RunConfig/RunId/GgufSource/TokenizerSource/ProviderKind)
- orchestration: group providers under provider_adapters/{docker_cluster,relay,vastai} and fold engine_builder/, config, run_fsm, run_plan, provisioning, resource_inventory, membership_readiness, and token_endpoint under orchestration/
- transport: consolidate codec registration into transport/codec_registry::register_mvp_actor_codecs (was crate::actors::register_mvp_actor_codecs) and rename actors/codec.rs to transport/json_codec.rs
- rename and relocate files into their domains (arena_manager->node_data/arena, actors/node_agent->node/actor, actors/orchestrator->orchestration/actor, stage_controller->staging/actor, telemetry/dashboard_view/etc->observability/, benchmark_observability->observability::benchmark, edge_establisher->node::edge_lifecycle, prompt_rpc->prompt::rpc) and update all crate:: imports accordingly
- remove the stale crates/mvp-system/specs/*.md (MVP_SYSTEM_MODULE_BOUNDARY_SPEC, mvp_chat, orchestrator) now that module boundaries live in mod.rs docs
