Bundled Plugins Are Allowed - -Plugins shipped in this source tree may be auto-registered by the host. - -That is acceptable coupling. - -What is not acceptable is embedding one plugin's runtime behavior directly into core mesh logic. Core mesh transport and state should stay generic. - -### 2. One Control Connection, Many Data Streams - -Each plugin process has one long-lived control connection. - -Use the control connection for: - -- initialize / health / shutdown -- manifest registration -- small RPC-style requests -- mesh event delivery -- stream negotiation -- cancellation - -Do not use the control connection for large uploads, downloads, or long-lived streaming responses. - -For large or streaming payloads, the host and plugin negotiate a short-lived side stream. - -### 3. MCP Is A Host Projection - -`mesh-llm` is the MCP server. - -Plugins do not need to implement MCP JSON-RPC directly. They declare MCP-facing services in the manifest, and the host `stapler` exposes them over MCP. - -### 4. HTTP Is A Host Projection - -`mesh-llm` owns the HTTP server. - -Plugins may declare HTTP bindings, but they do not need to run an HTTP server themselves. The host `stapler` maps HTTP requests onto plugin operations and resources. - -### 5. Capabilities Are Stable Product Contracts - -When `mesh-llm` wants a stable product API such as `/api/objects`, core should depend on a named capability like `object-store.v1`, not on a specific plugin ID like `blobstore`. - -## Architecture - -### Control Session - -There is one long-lived control session between host and plugin. - -The control session is used for: - -- plugin startup and manifest exchange -- health checks -- native service invocation requests and responses -- plugin-to-host notifications -- host-to-plugin mesh events -- opening and closing streams -- cancellation and error reporting - -The control session should stay responsive even while the plugin is sending or receiving large payloads. - -The native runtime contract is service-oriented, not MCP-oriented. - -The host invokes services such as: - -- operations -- prompts -- resources -- completions - -MCP method names like `tools/call` and `prompts/get` are projection-layer concerns. They are not the preferred host/plugin runtime contract. - -### Streams - -Streams are short-lived negotiated channels for a single request, response, or transfer. - -They are opened via the control session and then carry data independently. - -Streams are used for: - -- large HTTP request bodies -- large HTTP responses -- streaming uploads and downloads -- server-sent events or similar long-lived responses -- future bulk data flows between host and plugin - -On Unix, streams map to short-lived Unix sockets. - -On Windows, streams map to short-lived named pipes. - -The protocol concept is `stream`, not `socket`, so the transport binding remains platform-specific. - -### Why Streams Exist - -The current single-socket framed-envelope design is vulnerable to head-of-line blocking. Even chunked transfer traffic still competes with health checks, tool calls, mesh events, and other control messages on the same queue. - -This architecture avoids that by separating: - -- control plane traffic -- bulk and streaming data traffic - -## Manifest - -On startup, a plugin returns a manifest that declares what it provides to the host. - -Conceptually, the manifest contains: - -- plugin identity and version -- provided capabilities -- MCP contributions -- HTTP contributions -- inference contributions -- any mesh channel declarations the plugin needs - -The manifest is the source of truth for host projections. - -## Plugin Author Experience - -The primary design goal is very low boilerplate. - -The preferred DSL is surface-first: - -- `provides` -- `mcp` -- `http` -- `inference` -- `mesh` -- `events` - -Lifecycle hooks stay local to the plugin definition rather than becoming manifest items: - -- `startup_policy` -- `health` -- `on_initialized` -- `on_channel_message` -- `on_mesh_event` - -Each section is self-contained.

It keeps raw host RPC separate from the normal manifest-driven plugin surface. - -### Streaming - -Streaming is explicit in the DSL. - -For HTTP bindings, the preferred modifiers are: - -- `.stream_request()` -- `.stream_response()` -- `.sse()` - -These declare whether the request body, response body, or response format requires side-stream transport. - -## External Endpoints - -Plugins may register external services without proxying all traffic through the plugin process. - -This is a control-plane declaration, not a request proxying requirement. - -In practice: - -- attached external MCP servers are declared in the `mcp` section -- attached or plugin-hosted inference backends are declared in the `inference` section - -`mesh-llm` then talks to those services directly when appropriate. - -This keeps heavy data-plane traffic out of plugin IPC. - -### MCP Contributions - -The `mcp` section may contain both: - -- local MCP-facing items implemented by the plugin -- attached external MCP servers - -Preferred external forms include: - -- `external_stdio(...)` -- `external_http(...)` -- `external_tcp(...)` -- `external_unix_socket(...)` - -External MCP names are namespaced as: - -- `plugin_name.method` - -### Inference Contributions - -The `inference` section may contain both: - -- attached external OpenAI-compatible endpoints -- plugin-hosted inference providers - -Preferred forms include: - -- `openai_http(...)` for attached external endpoints -- `provider(...)` for plugin-hosted backends - -### Why Endpoint Registration Exists - -Some services already speak a protocol that `mesh-llm` knows how to use directly. - -Examples: - -- a local OpenAI-compatible inference server -- an external MCP server reachable over stdio, streamable HTTP, Unix socket, named pipe, or TCP -- a plugin-hosted inference runtime such as an MLX-backed local server - -In these cases, the plugin should remain the control-plane owner for: - -- discovery -- lifecycle -- readiness -- availability - -But `mesh-llm` should own the data plane when possible. - -### Health And Availability - -Endpoint health is separate from plugin health. - -If an endpoint health check fails: - -- the endpoint becomes unavailable -- the endpoint is removed from routing or aggregation -- the plugin remains loaded -- the plugin is not marked disabled -- the host keeps checking health - -If health returns: - -- the endpoint becomes available again automatically - -This is important because a plugin may be healthy while its managed or discovered service is: - -- starting -- restarting -- temporarily unhealthy -- reloading a model -- intentionally stopped - -The host should treat plugin liveness and endpoint liveness as separate concerns. - -### Recommended State Model - -Conceptually, the system should track at least: - -- plugin state -- endpoint state -- model or route availability - -Suggested plugin states: - -- `starting` -- `running` -- `degraded` -- `disconnected` -- `failed` - -Suggested endpoint states: - -- `unknown` -- `starting` -- `healthy` -- `unhealthy` -- `unavailable` - -Suggested routed availability states: - -- `advertised` -- `routable` -- `draining` -- `unavailable` - -Routing decisions should depend on endpoint health, not just plugin process health. - -## MCP - -MCP is implemented by the host, not by individual plugins. - -The plugin author marks which services should appear in MCP: - -- `tool(...)` -- `resource(...)` -- `resource_template_service(...)` -- `prompt(...)` -- `completion(...)` - -The host then synthesizes: - -- `tools/list` -- `tools/call` -- `resources/list` -- `resources/read` -- `prompts/list` -- `prompts/get` -- completions where applicable - -External MCP endpoints may also be aggregated into the host's MCP surface via the `endpoints:` declarations described above. - -### MCP Naming - -By default, tool, resource, and prompt names should be plugin-namespaced. - -Examples: - -- tool: `blackboard.feed` -- tool: `blackboard.post` -- resource: `blackboard://snapshot` -- prompt: `blackboard.status_brief` - -Friendly aliases may be added for bundled plugins, but the canonical identity should remain namespaced to avoid collisions. - -### MCP Streaming - -MCP-facing operations may be: - -- buffered -- streaming input -- streaming output -- streaming input and output - -For streaming operations, the host uses negotiated side streams internally rather than pushing large data through the control connection. - -## HTTP Bindings - -Plugins may declare HTTP bindings as part of the manifest. - -These bindings let a plugin feel native over HTTP without requiring custom host route code for each plugin. - -### Default Mounting - -Plugin-defined HTTP bindings should be mounted under a plugin-owned namespace by default. - -Examples: - -- `/api/plugins/blackboard/feed` -- `/api/plugins/blackboard/post` -- `/api/plugins/object-store/objects` - -This avoids collisions and keeps plugin-specific APIs out of the top-level product namespace unless explicitly promoted. - -### Promoted Product Routes - -Some routes may become stable product APIs owned by `mesh-llm`, for example: - -- `/api/objects` - -These routes should be backed by named capabilities, not by hard-coded plugin IDs. - -Example: - -- top-level route: `/api/objects` -- required capability: `object-store.v1` -- provider plugin: whichever plugin the host resolves for that capability - -This keeps product APIs stable while allowing the backing plugin to change. - -External endpoints do not automatically become HTTP routes. They are service registrations that the host may use for routing or aggregation according to their endpoint kind. - -### Buffered vs Streamed HTTP - -HTTP bindings may be declared as: - -- buffered request / buffered response -- streamed request / buffered response -- buffered request / streamed response -- streamed request / streamed response - -The host decides whether to keep the invocation on the control channel or negotiate a side stream based on the binding mode and payload size. - -## Streams And Large Transfers - -Large payloads must not ride the main control connection. - -Instead, the control session negotiates a short-lived stream for the transfer. - -Conceptual flow: - -1. host sends `OpenStream` -2. plugin accepts -3. host and plugin establish a short-lived local stream -4. request or response bytes flow on that stream -5. either side may cancel -6. stream is torn down and cleaned up - -This design supports: - -- 10 GB uploads -- large downloads -- long-lived streaming responses -- future websocket-like or SSE-style responses - -without blocking health checks or other control traffic. - -## Suggested Control Messages - -The exact wire format is still open, but the protocol should support concepts like: - -- `Initialize` -- `InitializeResponse { manifest }` -- `Health` -- `Shutdown` -- `Invoke` -- `InvokeResult` -- `Notify` -- `MeshEvent` -- `OpenStream` -- `OpenStreamResult` -- `CancelStream` -- `StreamError` - -The stream protocol itself may be raw bytes or lightly framed bytes, depending on the use case. - -## Capabilities - -Capabilities let core depend on behavior rather than on plugin names. - -Examples: - -- `object-store.v1` -- `mesh-blackboard.v1` -- `artifact-cache.v1` -- `model-catalog-provider.v1` - -Capabilities are used when: - -- core needs a stable product contract -- multiple plugins could satisfy the same role -- the host wants to promote a route into the top-level API - -Capabilities are not required for every plugin. They are mainly for shared contracts that `mesh-llm` itself depends on. - -Endpoint registration is related but distinct: - -- capabilities express stable contracts that core may depend on -- endpoints express concrete service instances that the host can talk to directly - -An endpoint may satisfy a capability, but the two ideas should remain separate in the design. - -## Mesh Channels - -Plugins may declare mesh channels for plugin-specific peer-to-peer coordination. - -These should use the generic plugin mesh transport rather than dedicated core stream types for individual plugins. - -Core should not embed plugin-specific wire protocols in the main mesh transport when the behavior can live behind the generic plugin channel mechanism. - -## What The Host Owns - -The host is responsible for: - -- launching plugins -- registering bundled plugins -- validating plugin identity -- keeping the control session alive -- stream negotiation and cleanup -- request validation -- HTTP mounting -- MCP exposure -- capability resolution -- route collision detection -- permissions and policy enforcement - -## What Plugins Own - -A plugin is responsible for: - -- declaring its manifest -- implementing handlers -- handling its own local state -- reading and writing stream payloads when invoked -- implementing any plugin-specific business logic - -## Non-Goals - -The plugin system should not require each plugin to: - -- run its own HTTP server -- run its own MCP server -- manually negotiate Unix socket paths in application code -- hard-code core route registration in `mesh-llm` - -The plugin system should also avoid: - -- top-level product APIs that are secretly bound to one plugin ID -- plugin-specific core mesh stream types when generic plugin channels are sufficient - -## Open Questions - -The following are intentionally left open for implementation design: - -- exact manifest schema -- exact control protocol message shapes -- exact stream framing format -- capability provider selection when multiple plugins implement the same capability -- whether promoted product routes are configured statically or negotiated dynamically -- how auth and policy rules are expressed for plugin-defined HTTP bindings - -## Architecture Baseline - -- bundled plugins may be auto-registered -- core mesh logic remains plugin-agnostic -- MCP and HTTP are first-class host projections -- product APIs depend on capabilities, not plugin IDs -- large data flows use negotiated side streams, not the control socket diff --git a/PLUGINS_PLAN.md b/PLUGINS_PLAN.md deleted file mode 100644 index 4bd759d66..000000000 --- a/PLUGINS_PLAN.md +++ /dev/null @@ -1,329 +0,0 @@ -# Plugins Plan - -This document tracks the implementation plan for the `mesh-llm` plugin architecture defined in [PLUGINS.md](./PLUGINS.md). - -## Sequencing Principles - -The work should land in this order: - -1.

Add crypto as a host-owned service surface only after the rest of the plugin surfaces are stable. - -## Proposed Sequence - -### Phase 1: Protocol And Manifest - -Define the v2 plugin control-plane protocol. - -This phase should specify: - -- plugin manifest schema -- plugin lifecycle messages -- request / response invocation model -- endpoint registration messages -- health and availability messages -- negotiated stream messages -- cancellation and error messages - -Target outputs: - -- manifest types -- protocol message types -- versioning / compatibility rules -- host and plugin runtime interfaces - -This is the foundation for everything else. - -### Phase 2: Host Runtime Core - -Implement the new host/plugin runtime without changing every feature at once. - -This phase should deliver: - -- one long-lived control connection per plugin -- negotiated short-lived streams -- plugin manifest registration on startup -- plugin health supervision -- endpoint health supervision -- separation of plugin state and endpoint state - -Target behavior: - -- plugins stay loaded even when managed endpoints become unavailable -- endpoint recovery automatically restores availability -- large or streaming payloads do not block the control connection - -### Phase 3: Manifest-Driven MCP - -Implement MCP as a host projection over manifest-declared plugin services. - -This phase should deliver: - -- manifest-declared tools -- manifest-declared resources -- manifest-declared resource templates -- manifest-declared prompts -- manifest-declared completions -- namespaced MCP aggregation in the host - -Target behavior: - -- plugins do not implement MCP JSON-RPC directly -- `mesh-llm` remains the MCP server -- external MCP endpoints can be aggregated later through the same host surface - -### Phase 4: Manifest-Driven HTTP Bindings - -Implement HTTP as a host projection over manifest-declared plugin services. - -This phase should deliver: - -- plugin-defined HTTP bindings -- default plugin-owned route namespacing -- buffered request / response support -- streamed request / response support using negotiated streams -- validation and error mapping in the host - -Target behavior: - -- plugin authors do not implement HTTP servers -- plugin-specific host route code is no longer required for each new plugin - -### Phase 5: Capability Resolution - -Add capability-based routing for stable product contracts. - -This phase should deliver: - -- named capability registration in plugin manifests -- host resolution of one provider for a capability -- optional promoted product routes backed by capabilities - -Examples: - -- `object-store.v1` -- `inference-endpoint-provider.v1` -- `mcp-endpoint-provider.v1` - -Target behavior: - -- core depends on capability contracts, not plugin IDs -- top-level product APIs can remain stable even if providers change - -### Phase 6: Endpoint Registration - -Implement concrete endpoint registration support. - -This phase should deliver: - -- inference endpoint registration -- external MCP endpoint registration -- endpoint descriptors -- endpoint health and availability tracking -- optional lifecycle hooks for plugin-managed services - -Target behavior: - -- plugins can register local or managed OpenAI-compatible inference servers -- plugins can register external MCP servers -- `mesh-llm` talks directly to those endpoints -- plugin IPC remains the control plane, not the data path - -### Phase 7: Migrate Existing Built-Ins - -Move built-in plugin behavior onto the new architecture. - -This phase should include: - -- moving blackboard fully behind generic plugin transport -- removing plugin-specific core mesh stream behavior where generic plugin channels are sufficient -- moving plugin-specific HTTP behavior behind manifest-driven bindings or capability routes - -Target behavior: - -- bundled plugins remain auto-registered -- core mesh logic becomes plugin-agnostic - -### Phase 8: Validation Plugins - -Build real plugins that exercise the design. - -The first plugin-hosted inference migration should be the current llama backend. - -After that, build an MLX endpoint provider plugin. - -After that, build at least one external MCP endpoint plugin. - -These plugins should validate: - -- endpoint registration -- endpoint health transitions -- direct host-to-endpoint communication -- capability resolution -- MCP aggregation -- HTTP binding ergonomics - -The llama pluginization work should move the current local llama-style serving path behind the new plugin-hosted inference endpoint contract. - -The MLX plugin should then take inspiration from the in-process inference-server work in [PR #103](https://github.com/Mesh-LLM/mesh-llm/pull/103), but implemented using the new plugin endpoint registration architecture rather than direct built-in runtime ownership in core. - -After that, add an attached external inference plugin, with Lemonade as the first target for that mode. That should take inspiration from [PR #150](https://github.com/Mesh-LLM/mesh-llm/pull/150), but implemented using endpoint registration rather than ad hoc `inference/register` notifications in the transport layer. - -### Phase 9: Host-Owned Plugin Crypto API - -Add host-owned crypto services for plugins. - -This phase should deliver: - -- `crypto.get_identity` -- `crypto.seal` -- `crypto.open` - -Target behavior: - -- plugins do not read the owner keystore directly -- plugins do not receive owner secret keys -- secret-key operations remain in the host process - -## Immediate Next Steps - -The best near-term execution order is: - -1. Write the manifest and protocol types. -2. Implement the new control connection and negotiated stream runtime. -3. Add manifest-driven MCP. -4. Add manifest-driven HTTP bindings. -5. Add endpoint registration and health tracking. -6. Pluginize the llama backend. -7. Build the MLX endpoint provider plugin. -8. Migrate blackboard off bespoke core behavior. -9. Add the host-owned crypto APIs. - -## Test Strategy - -The new plugin architecture needs explicit host/runtime integration tests in addition to unit tests. - -### MCP And HTTP Projection Testing - -Create fake MCP and HTTP servers plus dedicated test plugins that exercise projection behavior and failure modes. - -This test setup should validate: - -- manifest-declared MCP tools, resources, prompts, and completions -- manifest-declared HTTP bindings -- namespacing and collision handling -- buffered request / response behavior -- streamed request / response behavior -- negotiation and cleanup of short-lived streams -- cancellation behavior -- malformed payload handling -- timeout handling -- endpoint disappearance and recovery -- projection behavior when plugins are healthy but endpoints are not - -Include corner cases such as: - -- duplicate tool or route names -- invalid schemas or invalid manifests -- large request bodies -- large response bodies -- partial stream writes -- abrupt stream disconnects -- plugin restart while requests are in flight -- endpoint flapping between healthy and unhealthy - -### Inference Plugin Testing - -Use the pluginized llama backend first, then an MLX-backed inference plugin, to validate plugin-hosted inference endpoint registration end to end. - -This should validate: - -- endpoint registration -- model discovery -- request routing through the registered endpoint -- streaming response handling -- endpoint health transitions -- automatic endpoint recovery - -The pluginized llama backend should prove that the current built-in serving path can move behind the plugin contract without changing the host-facing inference model. - -The MLX plugin should then prove that a second plugin-hosted backend can use the same contract while owning its own runtime behavior. - -Take implementation cues from the current llama runtime behavior first, and then from [PR #103](https://github.com/Mesh-LLM/mesh-llm/pull/103): - -- plugin-hosted local model serving with llama semantics -- plugin-hosted local inference serving -- model discovery from the owned runtime -- direct routing through the registered endpoint -- endpoint health and lifecycle management separated from plugin liveness - -After that, validate the attached-external-endpoint mode with Lemonade: - -- connect to an already-running Lemonade endpoint -- perform health checks and model discovery -- register the endpoint and its models with the host -- mark the endpoint unavailable on health failure without unloading the plugin -- restore the endpoint automatically when health returns - -If MLX or Lemonade is not available locally, keep a fallback test mode with a fake OpenAI-compatible inference server for protocol and routing validation. - -### Explicit Follow-Up TODOs - -- once the llama backend is pluginized, keep MLX aligned to the same plugin-hosted inference endpoint contract - -### Additional Testing Needed - -Beyond fake MCP/HTTP servers and the MLX/Lemonade providers, we should also test: - -- backward compatibility of the plugin control protocol where required -- plugin startup and shutdown behavior -- host behavior when a plugin connects but never fully initializes -- host behavior when a plugin advertises endpoints and then disconnects -- capability resolution when zero, one, or multiple providers exist -- promoted product routes backed by capabilities -- plugin health vs endpoint health separation -- crypto host API behavior for `crypto.get_identity`, `crypto.seal`, and `crypto.open` -- security properties around short-lived stream naming, reuse, expiration, and cleanup -- concurrency with multiple plugins and multiple simultaneous streams -- platform behavior on both Unix sockets and Windows named pipes - -## Plugin Crypto API - -Plugins should not read the owner keystore directly and should not receive owner secret keys. - -Instead, the host should expose crypto operations to plugins. - -Initial API surface: - -- `crypto.get_identity` - - returns `owner_id` - - returns `signing_public_key` - - returns `encryption_public_key` - - returns `node_id` - -- `crypto.seal` - - host signs and encrypts for a recipient using the local owner keys - - returns a `SignedEncryptedEnvelope` - -- `crypto.open` - - host decrypts and verifies an incoming `SignedEncryptedEnvelope` - - returns the verified `OpenedMessage` - -This keeps owner secret-key operations inside the host process while still allowing plugins to use the signed+encrypted message primitives added by the owner keystore work. - -## Inference Plugin Testing - -When building and validating inference plugins, create an Ollama provider plugin first. - -The purpose of the Ollama provider plugin is to validate the inference endpoint registration model end to end: - -- plugin registers an inference endpoint with `mesh-llm` -- plugin reports endpoint health without becoming disabled when the endpoint is temporarily unavailable -- `mesh-llm` talks directly to the Ollama OpenAI-compatible endpoint rather than proxying inference through the plugin -- model discovery and routing work through the registered endpoint -- endpoint recovery makes the provider available again automatically - -This should be the first concrete inference-plugin test target before building more specialized inference providers. diff --git a/Package.swift b/Package.swift index c34d379af..cc7905180 100644 --- a/Package.swift +++ b/Package.swift @@ -6,12 +6,11 @@ let repoRoot = URL(fileURLWithPath: #filePath).deletingLastPathComponent().path let swiftSDKRelativePath = "sdk/swift" let ffiXCFrameworkRelativePath = "\(swiftSDKRelativePath)/Generated/MeshLLMFFI.xcframework" let ffiXCFrameworkPath = "\(repoRoot)/\(ffiXCFrameworkRelativePath)" -let remoteFFIXCFrameworkURL = "https://github.com/Mesh-LLM/mesh-llm/releases/download/__MESH_SWIFT_RELEASE_TAG__/MeshLLMFFI.xcframework.zip" -let remoteFFIXCFrameworkChecksum = "__MESH_SWIFT_RELEASE_CHECKSUM__" -let forceStubFFI = ProcessInfo.processInfo.environment["MESH_SWIFT_FORCE_STUB"] == "1" +let remoteFFIXCFrameworkURL = "https://github.com/Mesh-LLM/mesh-llm/releases/download/v0.73.1/MeshLLMFFI.xcframework.zip" +let remoteFFIXCFrameworkChecksum = "17a7d0cde0c7a078016239848a0a5af6e45696dfd9e4e938440a6489417f8370" let hasLocalFFIXCFramework = FileManager.default.fileExists(atPath: ffiXCFrameworkPath) -let hasRemoteFFIXCFramework = !forceStubFFI -

Build from source - -```bash -git clone https://github.com/Mesh-LLM/mesh-llm -cd mesh-llm -just build -``` - -Requires: `just`, `cmake`, Rust toolchain, Node.js 24 + npm. NVIDIA GPU builds need `nvcc` (CUDA toolkit). AMD GPU builds need ROCm/HIP. Vulkan GPU builds need the Vulkan development files plus `glslc`. CPU-only and Jetson/Tegra also work. For source builds, `just build` auto-detects CUDA vs ROCm vs Vulkan on Linux, or you can force `backend=rocm` or `backend=vulkan`. See [CONTRIBUTING.md](CONTRIBUTING.md) for details. - -Windows source builds are also supported for `cuda`, `rocm`/`hip`, `vulkan`, and `cpu` via `just build`. Metal remains macOS-only. Tagged stable GitHub releases publish macOS bundles plus Linux CPU, Linux ARM64 CPU, Linux CUDA, Linux ROCm, and Linux Vulkan bundles. Prereleases use the same workflow and can optionally skip the Linux CUDA, Linux ROCm, and Linux Vulkan bundles. The Linux ARM64 CPU artifact is `mesh-llm-aarch64-unknown-linux-gnu.tar.gz`. In install and release contexts, `arm64` and `aarch64` mean the same 64-bit ARM target, and generic 32-bit ARM is not a published release target. Windows publish jobs are currently commented out in `.github/workflows/release.yml`, but you can still generate the matching local Windows artifacts with `just release-build-windows`, `just release-build-cuda-windows`, `just release-build-rocm-windows`, `just release-build-vulkan-windows`, and the matching `release-bundle-*-windows` recipes. - -## Run -Once installed, you can run: - -```bash -mesh-llm serve --auto # join the best public mesh, start serving -``` - -That's it. Downloads a model for your hardware, connects to other nodes, and gives you an OpenAI-compatible API at `http://localhost:9337`. - -Or start your own: -```bash -mesh-llm serve --model Qwen2.5-32B # downloads model (~20GB), starts API + web console -mesh-llm serve --model Qwen2.5-3B # or a small model first (~2GB) -``` - -Add another machine: -```bash -mesh-llm serve --join # token printed by the first machine -``` - -Or discover and join public meshes: -```bash -mesh-llm serve --auto # find and join the best mesh -mesh-llm client --auto # join as API-only client (no GPU) -``` - -## How it works - -Every node gets an OpenAI-compatible API at `http://localhost:9337/v1`. Distribution is automatic — you just say `mesh-llm serve --model X` and the mesh figures out the best strategy: - -- **Model fits on one machine?** → runs solo, full speed, no network overhead -- **Dense model too big?** → pipeline parallelism — layers split across nodes -- **MoE model too big?** → expert parallelism — experts split across nodes, zero cross-node traffic - -If a node has enough VRAM, it always runs the full model. Splitting only happens when it has to. -Currently using a lightly forked version of llama.cpp (see the Justfile for where it pulls branch from). - -**Pipeline parallelism** — for dense models that don't fit on one machine, layers are distributed across nodes proportional to VRAM. llama-server runs on the highest-VRAM node and coordinates via RPC. Each rpc-server loads only its assigned layers from local disk. Latency-aware: peers are selected by lowest RTT first, with an 80ms hard cap — high-latency nodes stay in the mesh as API clients but don't participate in splits. - -**MoE expert parallelism** — Mixture-of-Experts models (Qwen3-MoE, GLM, OLMoE, Mixtral, DeepSeek — increasingly the best-performing architectures) are auto-detected from the GGUF header. The mesh reads expert routing statistics to identify which experts matter most, then assigns each node an overlapping shard: a shared core of critical experts replicated everywhere, plus unique experts distributed across nodes. Each node gets a standalone GGUF with the full trunk + its expert subset and runs its own independent llama-server — zero cross-node traffic during inference. Sessions are hash-routed to nodes for KV cache locality. - -**Multi-model** — different nodes serve different models simultaneously. The API proxy peeks at the `model` field in each request and routes to the right node via QUIC tunnel. `/v1/models` lists everything available. - -**Demand-aware rebalancing** — a unified demand map tracks which models the mesh wants (from `--model` flags, API requests, and gossip). Demand signals propagate infectiously across all nodes and decay naturally via TTL. Standby nodes auto-promote to serve unserved models with active demand, or rebalance when one model is significantly hotter than others. When a model loses its last server, standby nodes detect it within ~60s. - -**Inter-model collaboration** — models on the mesh help each other during inference. When a text-only model receives an image, it silently consults a vision model on the mesh for a caption and generates from that. When a small model is uncertain, it races two peers for a second opinion and injects the winner's answer as context. When a model gets stuck in a repetition loop, another model nudges it out. The caller sees one seamless response — they don't know multiple models collaborated. Inspired by [Mixture of Models (NSED)](https://arxiv.org/pdf/2601.16863) — the mesh is the ensemble. See [VIRTUAL_LLM.md](mesh-llm/docs/VIRTUAL_LLM.md). - -**Latency design** — the key insight is that HTTP streaming is latency-tolerant while RPC is latency-multiplied. llama-server always runs on the same box as the GPU. The mesh tunnels HTTP, so cross-network latency only affects time-to-first-token, not per-token throughput. RPC only crosses the network for pipeline splits where the model physically doesn't fit on one machine. - -### Network optimizations - -- **Zero-transfer GGUF loading** — `SET_TENSOR_GGUF` tells rpc-server to read weights from local disk. Dropped model load from 111s → 5s. -- **RPC round-trip reduction** — cached `get_alloc_size`, skip GGUF lookups for intermediates. Per-token round-trips: 558 → 8. -- **Direct server-to-server transfers** — intermediate tensors pushed directly between rpc-servers via TCP, not relayed through the client. -- **Speculative decoding** — draft model runs locally on the host, proposes tokens verified in one batched forward pass. +38% throughput on code (75% acceptance). - -## Usage - -### Start a mesh -```bash -mesh-llm serve --model Qwen2.5-32B -``` -Starts serving a model and prints an invite token. This mesh is **private** — only people you share the token with can join. - -To make it **public** (discoverable by others via `--auto`): -```bash -mesh-llm serve --model Qwen2.5-32B --publish -``` - -### Join a mesh -```bash -mesh-llm serve --join # join with invite token (GPU node) -mesh-llm client --join # join as API-only client (no GPU) -``` - -### Named mesh (buddy mode) -```bash -mesh-llm serve --auto --model GLM-4.7-Flash-Q4_K_M --mesh-name "poker-night" -``` -Everyone runs the same command. First person creates it, everyone else discovers "poker-night" and joins automatically. `--mesh-name` implies `--publish` — named meshes are always published to the directory. - -### Auto-discover -```bash -mesh-llm serve --auto # discover, join, and serve a model -mesh-llm client --auto # join as API-only client (no GPU) -mesh-llm discover # browse available meshes -mesh-llm gpus # inspect local GPUs and stable IDs -``` - -### Inspect and clean the shared model cache -```bash -mesh-llm models installed -mesh-llm models cleanup --unused-since 30d -mesh-llm models cleanup --unused-since 30d --yes -``` - -`models installed` now shows whether a cached model is mesh-managed or external plus the last time mesh-llm used it. `models cleanup` only removes model files that mesh-llm explicitly marked as mesh-managed; by default it prints a dry run preview and requires `--yes` to delete anything. - -### Multi-model -```bash -mesh-llm serve --model Qwen2.5-32B --model GLM-4.7-Flash - -# Route by model name -curl localhost:9337/v1/chat/completions -d '{"model":"GLM-4.7-Flash-Q4_K_M", ...}' -``` -Different nodes serve different models. The API proxy routes by the `model` field. - -### Inspect local GPUs -```bash -mesh-llm gpus -mesh-llm gpus --json -mesh-llm gpu benchmark --json -``` - -`mesh-llm gpus` prints local GPU entries, backend device names, stable IDs, VRAM, unified-memory state, and cached bandwidth when a benchmark fingerprint is already available. Add `--json` for machine-readable inventory output, or run `mesh-llm gpu benchmark --json` to refresh the local fingerprint and print the benchmark result as JSON. - -Use only pinnable `Stable ID` / `stable_id` values from `mesh-llm gpus` or `mesh-llm gpus --json` for pinned startup config. Stable-ID fallback values such as `index:*` or backend-device names like `CUDA0` / `HIP0` / `MTL0` can still be printed for inventory purposes, but they are not valid pin targets. - -### Startup config - -`mesh-llm serve` can now load startup models from `~/.mesh-llm/config.toml`: - -```toml -version = 1 - -[gpu] -assignment = "pinned" - -[[models]] -model = "Qwen3-8B-Q4_K_M" -gpu_id = "pci:0000:65:00.0" - -[[models]] -model = "bartowski/Qwen2.5-VL-7B-Instruct-GGUF/qwen2.5-vl-7b-instruct-q4_k_m.gguf" -mmproj = "bartowski/Qwen2.5-VL-7B-Instruct-GGUF/mmproj-f16.gguf" -ctx_size = 8192 -gpu_id = "uuid:GPU-12345678" - -[[plugin]] -name = "blackboard" -enabled = true -``` - -Start with the default config path: - -```bash -mesh-llm serve -``` - -If no startup models are configured, `mesh-llm serve` prints a `⚠️` warning, shows help, and exits. - -Or point at a different file: - -```bash -mesh-llm serve --config /path/to/config.toml -``` - -Precedence rules: - -- Explicit `--model` or `--gguf` ignores configured `[[models]]`. -- Explicit `--ctx-size` overrides configured `ctx_size` for the selected startup models. -- Plugin entries still live in the same file. - -Pinned startup notes: - -- `assignment = "pinned"` requires every configured `[[models]]` entry to include a `gpu_id`. -- Valid `gpu_id` values come from the pinnable stable IDs reported by `mesh-llm gpus` / `mesh-llm gpus --json`, not fallback inventory IDs. -- Pinned configs fail closed when a configured ID is missing, ambiguous, unsupported on the local backend, or no longer resolves on the current machine. -- Explicit `--model` / `--gguf` still bypass configured `[[models]]`, so they also bypass config-owned pinned `gpu_id` values. - -### No-arg behavior -```bash -mesh-llm # no args — prints --help and exits -``` -Does not start the console or bind any ports.

Let GitHub Actions build and publish the release - -Running `.github/workflows/release.yml` via `workflow_dispatch` triggers the release flow, which: - -- builds the Swift XCFramework zip on macOS before the tag exists so SwiftPM gets the exact release URL and checksum baked into the tagged `Package.swift` -- creates and pushes the release commit and tag before any build jobs start -- serializes releases so two manual runs cannot race each other -- builds release bundles on macOS, Linux CPU, and Linux ARM64 CPU -- also builds Linux CUDA, Linux ROCm, and Linux Vulkan unless `skip_gpu_bundles=true` is set on a prerelease run -- keeps the Windows publish block commented out for now, so GitHub release publishing does not currently upload Windows bundles -- still leaves the local Windows bundle recipes available in `Justfile` for manual builds -- uploads `MeshLLMFFI.xcframework.zip` for Swift Package Manager consumers -- publishes the Android AAR to GitHub Packages as `ai.meshllm:meshllm-android:` -- uploads versioned assets such as `mesh-llm-v0.X.0-aarch64-apple-darwin.tar.gz` -- uploads the Linux ARM64 CPU asset as `mesh-llm-aarch64-unknown-linux-gnu.tar.gz` -- uploads stable `latest` assets such as `mesh-llm-x86_64-unknown-linux-gnu.tar.gz` -- uploads CUDA-specific Linux assets such as `mesh-llm-x86_64-unknown-linux-gnu-cuda.tar.gz` -- uploads ROCm-specific Linux assets such as `mesh-llm-x86_64-unknown-linux-gnu-rocm.tar.gz` -- uploads Vulkan-specific Linux assets such as `mesh-llm-x86_64-unknown-linux-gnu-vulkan.tar.gz` -- keeps the legacy macOS `mesh-bundle.tar.gz` asset available for direct archive installs -- creates the GitHub release automatically with generated notes -- marks hyphenated tags such as `v0.X.0-rc.1` as GitHub prereleases -- publishes `mesh-llm-client` and `mesh-api` to crates.io after the release succeeds, including prerelease tags such as `v0.X.0-rc.1` -- resets the target branch back to the placeholder Swift `Package.swift` after the release finishes, so day-to-day branch builds do not keep pointing at the most recent published XCFramework - -### 6a. Autoupdater behavior and compatibility - -- Stable releases still use GitHub's `releases/latest` endpoint, so ordinary installs only see stable releases. -- GitHub prereleases are excluded from `releases/latest`, so publishing `v0.X.0-rc.1` does not advertise that prerelease to older stable clients. -- This change updates mesh-llm's version comparison to proper semver ordering, so a prerelease binary such as `0.X.0-rc.1` will correctly upgrade to the eventual stable `0.X.0` release, or to a specific tagged release when you run `mesh-llm update --version vX.Y.Z`. -- Older binaries that predate this change use a dot-splitting numeric comparison instead of semver. If one of those binaries somehow carries a prerelease version string such as `0.X.0-rc.1`, it can mis-order versions and may fail to recognize `0.X.0` or `0.X.1` as newer. In practice that only affects manually produced prerelease builds, because the old release tooling did not support `-rc.N` tags. -- Result: the change is backward compatible for existing stable users, and it fixes updater behavior for official prerelease builds going forward. - -### 7.

Deleting the custom cache was a 38% speedup. Same lesson as PostgreSQL's `shared_buffers`: don't take more than 25% of RAM. -- **pread() >> mmap() for expert loading.** mmap triggers 240 individual page faults for a 3.9MB expert (240 × 16KB pages). One `pread()` call issues one NVMe command. 5× faster. -- **2-bit expert quantization preserves quality.** 44% size reduction over 4-bit, RMSE ~0.001. Quality holds across math, code, reasoning.

Survey current hardware. -2. Exit cleanly with a clear message if no GPUs are present. -3. Detect the correct platform-specific benchmark binary. -4. Run the benchmark with the existing timeout behavior. -5. Atomically rewrite `~/.mesh-llm/benchmark-fingerprint.json`. -6. Print a short success summary including: - - GPU count - - total measured bandwidth - - fingerprint cache path - -## Important constraints - -- Keep `mesh-llm gpus` read-only. -- Do not silently reuse the cache for `gpu benchmark`. -- Reuse existing benchmark binary discovery and parsing logic. -- Preserve current atomic write behavior using the temp-file-plus-rename path. -- Surface soft failures clearly to the user. - -## Edge cases to handle - -### No GPU present - -- Current runtime and benchmark code already short-circuit when `gpu_count == 0`. -- The new CLI should print a clear user-facing message and avoid writing a new fingerprint file. - -### Missing benchmark binary - -- `detect_benchmark_binary()` can return `None` for unsupported or missing platform binaries. -- The CLI should report that explicitly instead of failing silently. - -### Benchmark timeout - -- Reuse existing timeout behavior from `run_benchmark()`. -- If the benchmark times out or exits unsuccessfully, do not claim success and do not present stale results as fresh. - -### Parse failures or invalid output - -- If benchmark JSON is empty, malformed, or reports an error object, surface that as a benchmark failure. - -### Existing cache present - -- The command should overwrite the existing fingerprint file with a newly generated one. -- The force path must bypass normal cache reuse. - -## Validation plan - -### Unit tests - -Add or extend tests in `mesh-llm/src/system/benchmark.rs` to cover: - -- forced rerun path bypasses cache reuse -- forced path rewrites the fingerprint file -- no-GPU path does not write a new cache -- missing-binary path fails cleanly - -### CLI verification - -Verify manually or with command-level tests that: - -- `mesh-llm gpus` still shows current GPU inspection output -- `mesh-llm gpu benchmark` is accepted by clap -- `mesh-llm gpu benchmark` rewrites the fingerprint file even when one already exists -- error cases produce clear output - -### Regression checks - -- Ensure startup benchmarking still uses the normal cached path. -- Ensure existing `gpus` output formatting remains unchanged unless intentionally improved. - -## Summary - -This should be implemented as a small CLI expansion plus a focused benchmark helper in `system/benchmark.rs`. The key design requirement is that `mesh-llm gpu benchmark` must bypass cache reuse and always regenerate and rewrite `benchmark-fingerprint.json`, while the existing `mesh-llm gpus` path remains a read-only inspector of cached data. diff --git a/ci/ci.md b/ci/ci.md new file mode 100644 index 000000000..9d7f53fc9 --- /dev/null +++ b/ci/ci.md @@ -0,0 +1,270 @@ +```mermaid +flowchart TD + subgraph Triggers["Pull request triggers"] + PR["opened / synchronize / reopened / ready_for_review"] + end + + subgraph Changes["compute-changes"] + Files["changed files"] + Affected["affected crates + reverse deps"] + ClippyBins["clippy binpack\nplan-clippy-batches.sh"] + Backend["backend_changed?"] + BackendRecipe["backend_recipe_changed?"] + InferenceArtifact["inference_artifact_required?"] + WindowsCPU["windows_cpu_build_required?"] + WindowsGPU["windows_gpu_build_required?"] + SDK["sdk_smoke_required?"] + Website["website_changed?"] + WebsiteDocs["website_docs_changed?"] + CLIDocs["cli_surface_changed?"] + Docs["docs_only?"] + end + + PR --> Files --> Affected + Affected --> ClippyBins + Files --> Backend + Files --> BackendRecipe + Files --> WindowsCPU + Files --> WindowsGPU + BackendRecipe --> Backend + BackendRecipe --> WindowsCPU + BackendRecipe --> WindowsGPU + Affected --> InferenceArtifact + Backend --> InferenceArtifact + SDK --> InferenceArtifact + Affected --> SDK + Files --> Website + Files --> WebsiteDocs + Files --> CLIDocs + Files --> Docs + + subgraph Quality["pr_quality.yml · PR Quality Checks"] + direction TB + Fmt["rust-fmt"] + Clippy["rust-clippy matrix\nweighted affected-crate bins"] + UIQ["ui-quality\nReact console"] + CLIDocsSync["cli-docs-sync\nCLI surface requires public docs"] + QSummary["summary"] + Fmt --> QSummary + Clippy --> QSummary + UIQ --> QSummary + CLIDocsSync --> QSummary + end + + subgraph WebsitePR["pr_website.yml · PR Website Checks"] + direction TB + WebsiteBuild["website-build\nEleventy/Tailwind/Pagefind"] + WebsiteSummary["summary"] + WebsiteBuild --> WebsiteSummary + end + + ClippyBins --> Clippy + Affected --> Fmt + Files --> UIQ + Website --> WebsiteBuild + WebsiteDocs --> CLIDocsSync + CLIDocs --> CLIDocsSync + +subgraph PRCI["pr_builds.yml · PR Builds"] + direction TB + subgraph Producers["top-level target jobs"] + LinuxCPU["linux_cpu_artifact\ndebug mesh-llm · CLI smoke\n→ ci-linux-inference-binaries"] + LinuxTests["linux_test_groups matrix\nSDK/API · Skippy · unit · protocol · Skippy smoke"] + LinuxTargets["linux_targets matrix\nCUDA / ROCm / Vulkan rows build when backend_changed"] + WindowsTargets["windows_targets matrix\nCPU / CUDA / ROCm / Vulkan\nfull builds only for Windows inputs"] + MacCPU["macos_cpu_artifact\nmacOS Metal build · CLI smoke\n→ ci-macos-inference-binaries"] + MacTests["macos_unit_tests"] + MacTargets["macos_targets matrix\nCUDA / ROCm / Vulkan explicit skips"] + end + + subgraph Smokes["artifact-consuming smokes"] + Restore["restore-smoke-inputs action\ndownload artifact · stage binary · restore model"] + Inference["smoke.yml\nLinux inference + OpenAI + split serving"] + Scripted["scripted-binary-smoke.yml\ntwo-node client/serving"] + SDKSmoke["sdk-smoke.yml\nnative · Kotlin · Swift"] + end + end + + Docs -.

Its summary job writes a Markdown table to + `$GITHUB_STEP_SUMMARY` instead of printing a terminal-only table. +- `pr_website.yml` is named **PR Website Checks** and owns the public website PR + canary. It uses `.github/actions/compute-changes` and runs + `website-build` only when `website_changed` is true, or when manually + dispatched, so public website validation is separate from Rust/React-console + quality checks while still using the central routing signals. +- `ui_changed` and `website_changed` intentionally describe different products: + `ui_changed` is only the embedded React console under `crates/mesh-llm-ui/**`, + while `website_changed` is only the public Eleventy/Tailwind/Pagefind website + and its passthrough inputs. Website changes do not trigger React console UI + quality or UI artifact rebuilds. +- CLI surface changes in `crates/mesh-llm-cli/src/{parser,models,runtime,benchmark}.rs` + set `cli_surface_changed`. When that flag is true, `cli-docs-sync` requires a + public website docs/example update under `website/src/docs/pages/` or + `website/src/_includes/`, with `website/src/docs/pages/CLI.md` as the primary + command reference. +- `pr_builds.yml` is named **PR Builds** and owns PR target jobs plus integration + and smoke validation. Linux and macOS CPU artifact jobs upload the binaries + that downstream smoke jobs consume before long validation groups finish; + Linux test groups run SDK/API, Skippy, unit, protocol, and Skippy smoke work + as parallel matrix rows. Linux/macOS backend matrices remain separate from the + CPU artifact producers. +- `rust_changed` is not an artifact-build signal. Rust tooling changes such as + `tools/xtask/**` still run PR Quality formatting/clippy, but PR Builds only + builds `mesh-llm` artifacts when `inference_artifact_required` is true: a + runtime-facing crate, SDK smoke input, React console UI artifact input, + backend/native input, all-rust fail-open/escalation, or manual dispatch. +- `Justfile` is routed by changed hunks, not by path alone. Website/dev recipe + edits stay light, while native build, ABI, release, bundle, and package + recipe edits set `backend_recipe_changed`, which feeds backend artifacts and + Windows CPU/GPU build eligibility. +- Workflow/orchestration-only PR edits validate the PR routing graph without + becoming Rust crate changes. They must not fan out into Linux/macOS artifact + producers, native backend, Windows GPU, benchmark, or SDK-smoke lanes unless a + changed file also affects Rust crates, React console UI assets, public website + inputs, SDK inputs, or backend products. Backend lanes are reserved for files + that can affect native ABI/backend products, such as `third_party/llama.cpp/**`, + `crates/skippy-ffi/**`, backend build scripts, backend-relevant Justfile + hunks, and `.github/cache-version.txt`. +- Windows target jobs use compute-changes' `windows_cpu_build_required` and + `windows_gpu_build_required` outputs for full platform builds. The CPU row can + still run lightweight Windows cargo checks for broad Rust changes, but + CUDA/ROCm/Vulkan rows stay skipped unless Windows GPU inputs changed, + backend-relevant Justfile hunks changed, or the workflow is manually + dispatched. +- `pr_cleanup.yml` deletes PR merge-ref caches and artifacts from positively + matched PR workflow runs when a pull request closes. Cache cleanup first plans + deterministic shards, then fans deletion out across + `vars.PR_CACHE_CLEANUP_WORKERS` workers (default `5`) while keeping each worker + serial and rate-limited; a final summary aggregates cache shard results plus + artifact cleanup. Cleanup-only workflow edits do not fan out into + Rust/build/smoke jobs. +- Docker image validation and publishing are intentionally not part of pull + request CI; non-PR workflows (`ci.yml`, `website-pages.yml`, `docker.yml`, + `release.yml`) own main, dispatch, tag, website deployment, and release-grade + publishing behavior. +- `fly-deploy-console.yml` is a manual (`workflow_dispatch`) deploy of the + `mesh-llm-console` Fly app. It builds the image on Fly's remote builders from + `fly/Dockerfile` and authenticates with the app-scoped `FLY_API_TOKEN` repo + secret. It carries no pull request trigger and does not run release or smoke + jobs. + +## Public website deployment + +- `website-pages.yml` deploys the public static site through GitHub Pages' Actions + deployment path. It runs on pushes to `main` that change `website/**`, the root + install scripts that Eleventy copies into the site, or the deploy workflow + itself, and it can also be run manually with `workflow_dispatch`. +- The deploy workflow cleans generated website output, builds from `website/` + with `npm ci && npm run build`, stages only the generated public-site paths + into `public-website-artifact`, and deploys that artifact with + `actions/deploy-pages` using the custom `Public Website` environment. The + checked-in `docs/` tree is no longer the Pages source of truth once repository + Pages settings use the Actions build type. +- Manual `workflow_dispatch` runs are guarded to the `main` ref so the public + website cannot be deployed from an arbitrary branch by accident. +- Public website deployment stays separate from PR website quality checks: + `pr_website.yml` proves that website sources build, while `website-pages.yml` + owns publishing the generated artifact after merge to `main`. + +## Artifact and smoke reuse + +- Smoke jobs restore binaries through `.github/actions/restore-smoke-inputs` and + reusable workflows instead of rebuilding `mesh-llm` or patched llama.cpp. +- `restore-smoke-inputs` also owns the single-GGUF smoke model cache used by + inference, scripted two-node, and SDK smokes. The Skippy CI smoke lanes + restore a separate two-model cache for dense and recurrent GGUF fixtures, and + `hf-download-smoke.yml` points the Rust HF integration tests at a cached model + directory via `MESH_HF_DOWNLOAD_TEST_CACHE_DIR`. +- Shared model caches are restored in PRs and saved only from trusted `main` + runs. +- Linux CPU artifacts feed inference, two-node, native SDK, and Kotlin SDK + smokes. macOS CPU artifacts feed Swift SDK smokes. +- Linux native-runtime packaging uses `patchelf` to make packaged shared + libraries relocatable with `$ORIGIN`, then verifies them without + `LD_LIBRARY_PATH`. Release native-runtime jobs and Linux SDK smoke jobs need + `patchelf` because SDK smoke prepares native runtime packages through + `scripts/ci-prepare-native-runtime.sh`. +- Artifact-consuming smokes are additionally gated on the matching CPU producer + being eligible, so backend-only or cleanup-only PRs skip those jobs natively + instead of attempting to download an artifact that was never uploaded. +- PR and smoke-only CI artifacts use `retention-days: 1`; PR cleanup removes + matched PR-run artifacts proactively. +- Direct `mesh-llm` invocations in workflows and CI scripts must include + `--log-format json`. + +## PR CI performance heuristics + +Use these checks when reviewing PR CI wall-clock regressions: + +- **Critical path minutes**: compare the first job start to the last required job + finish, then identify the longest required job. Workflow/orchestration-only + changes should complete after routing validation instead of being dominated by + Linux/macOS artifacts, Windows, backend, or SDK smoke jobs. +- **Heavy-lane eligibility**: every expensive backend/platform lane should be + traceable to `backend_changed`, `windows_cpu`, `windows_gpu`, or + `sdk_smoke_required`. If a workflow/doc-only edit triggers CUDA, ROCm, Vulkan, + Windows release builds, or Swift/Kotlin SDK smokes, routing is too broad. +- **Duplicate work count**: smoke jobs should consume uploaded Linux/macOS + binaries through `.github/actions/restore-smoke-inputs`; they should not build + `mesh-llm` or patched llama.cpp again. +- **Prewarmed ABI cache hit ratio**: Windows ABI cache keys in PR Builds must + match the trusted `windows-warm-caches.yml` keys. Check + `gh cache list --branch main --limit 100` for + `mesh-llm-windows-2025-skippy-abi-*` entries before + treating a slow Windows miss as expected. +- **Runner routing**: platform-specific work should run on its native runner + class (Blacksmith Windows 2025 for Windows ABI products, Blacksmith macOS for Swift/Metal, Linux + for Linux backends) and skip unsupported combinations explicitly. + +For agent-facing workflow editing rules, see `.github/AGENTS.md`. diff --git a/ci/linux-test.dockerfile b/ci/linux-test.dockerfile index a0980e39d..e36ddd46e 100644 --- a/ci/linux-test.dockerfile +++ b/ci/linux-test.dockerfile @@ -2,7 +2,7 @@ # Run from repo root: docker build -f ci/linux-test.dockerfile -t mesh-llm-ci . # # NOTE: npm ci may fail behind SSL-intercepting proxies.

Raw-multicast LAN beacon for relay-less direct-path bootstrapping. +//! +//! On multi-homed hosts (many utun/VPN interfaces) both the mDNS service +//! daemon and iroh's relay-less initial handshake can fail to traverse the LAN, +//! because they rely on per-packet source selection that the macOS kernel +//! routes onto the wrong interface. A plain UDP socket *bound to the LAN IP* +//! with `IP_MULTICAST_IF` pinned to that interface reaches LAN peers reliably. +//! +//! This beacon uses exactly that reliable mechanism, independent of mDNS: +//! every node in mDNS mode periodically multicasts its own reachable +//! `EndpointAddr` (plus mesh id) on a dedicated group/port, and listens for +//! peers' beacons. On hearing a peer it is not connected to, it dials that +//! peer's advertised address — the single-homed → multi-homed direction that +//! works. `connect_to_peer` is idempotent, so whichever side connects first +//! wins and duplicates are harmless. +//! +//! The beacon carries no trust-bearing material: only an endpoint id, LAN +//! addresses, and a mesh-id fingerprint. Admission is still enforced by the +//! mesh handshake.
