The actual backend +is always reported: + +- `wasm` is the preferred result; +- a native or JavaScript fallback is allowed for portability; +- `homecore wasm status --strict` fails when WASM is unavailable; +- fallback execution is never relabelled as WASM. + +The kernel specification and generated host configuration pin the current +package version. Packaged project templates invoke an already-installed +`homecore` binary; no committed MCP configuration executes +`homecore@latest`. + +This kernel boundary is separate from application plugins. Homecore's plugin +architecture remains: + +- native plugins are compiled in and registered explicitly; +- external packages are bounded, path-checked, signature-verified Wasm; +- Wasmtime execution is opt-in through Cargo features; +- arbitrary native dynamic libraries are not loaded. + +The `wasm` verification profile runs the Wasmtime-specific plugin and server +tests from fixed argument arrays with `shell: false`. + +### 2. CLI and MCP surface + +The CLI provides: + +- source-cited `guidance` and `capabilities`; +- reviewed local `brain search`, citation verification, and proposal output; +- `doctor` and strict/non-strict WASM diagnostics; +- fixed `core`, `wasm`, `hap`, and `full` verification profiles; +- skills and tool-schema discovery; +- an MCP stdio server; +- configuration output for Claude Code and Codex; +- guarded local host delegation. + +The MCP server exposes only: + +- `homecore_guidance`; +- `homecore_wasm_status`; +- `homecore_doctor`; +- `homecore_memory_search`. + +All MCP tools are read-only. The fixed verification profiles remain local CLI +commands because Cargo writes build artifacts, executes repository code, and +may consume substantial resources. There are no MCP tools for test execution, +server start, migration writes, pairing, plugin installation, agent +delegation, GitHub mutation, release, or publication. + +JSON-RPC request size, queue depth, per-process tool-call budget, output, and +tool/subprocess duration are bounded. Tool schemas reject unknown fields. +Repository roots are realpath-verified against fixed RuView/Homecore markers. +Child processes use argument arrays, `shell: false`, a scrubbed environment, +bounded output, and secret redaction. MCP repository access is anchored once +at server startup from the launch checkout or `HOMECORE_TRUSTED_REPO`; request +arguments cannot self-declare a new trust root. + +### 3. Local Claude Code and Codex adapters + +Both adapters operate on an exact trusted checkout and consume prompts through +stdin. + +Codex uses: + +- `codex exec -`; +- `-C `; +- `--sandbox read-only` by default; +- ephemeral JSONL output; +- strict configuration parsing; +- ignored user config while repository exec-policy rules remain active. + +Claude Code uses: + +- `claude -p --safe-mode`; +- plan mode with read/search tools by default; +- JSON output; +- no session persistence. + +Workspace writes require both `--allow-write` and `--confirm`. Neither adapter +emits a permission or sandbox bypass. Host delegation is CLI-only and is not +reachable through MCP, avoiding recursive agent authority. + +### 4. Reviewed guidance and shared brain + +Capability records carry: + +- an honest maturity label; +- repository source paths; +- fixed validation commands; +- explicit limitations. + +Canonical brain records are committed, reviewed, bounded, evidence-labelled, +source-relative, and digest-covered. Search is deterministic. `brain propose` +prints an unreviewed JSONL candidate and never edits canonical knowledge. +Retrieved content is evidence, not instruction or permission. Private vector +indexes, overlays, and raw transcripts remain untracked and unpackaged. + +No Darwin/Flywheel candidate can self-promote through this harness. A future +learning loop requires a separate reviewed decision and the same frozen +holdout, provenance, security, and maintainer gates as ADR-283. + +### 5. Distribution and release + +Extend the ADR-265 npm matrix and provenance-only release workflow to +`harness/homecore`. The gate must run on supported Node versions and verify: + +- exact lockfile installation; +- tests and security tests; +- package version single-sourcing; +- an explicit unpacked-size budget and no source maps; +- installation and execution from the real tarball; +- the WASM backend from the installed tarball; +- MCP initialization and exports; +- README claim checking; +- the package provenance manifest. + +Publication remains CI-only with npm provenance. The release job runs on a +trusted-publishing-compatible Node/npm runtime, accepts only `main`, uses the +protected `npm-release` environment, and publishes the exact digest-checked +tarball that passed smoke tests. The environment must restrict deployment to +`main`, require review, and prevent self-review. The unscoped npm name being +available during development is not treated as permanent ownership; release +must still confirm registry access and package identity. + +## Consequences + +### Positive + +- Contributors get a focused `npx homecore` entry point without coupling the + Rust server to an agent framework. +- WASM is used for the portable kernel and explicitly exercised for Homecore + plugin verification. +- Capability guidance can distinguish implemented code, feature gates, + provider requirements, ecosystem limitations, and certification boundaries. +- Local agent execution is portable across Claude Code and Codex while + remaining read-only by default. +- MCP authority is small enough to audit and contains no direct home, network, + GitHub, or release mutation. + +### Negative + +- `homecore` is a narrow exception to the `@ruvnet/*` package namespace rule. +- The package adds one exact runtime dependency for the WASM kernel. +- The Wasmtime and HAP verification profiles can be expensive and write Cargo + build artifacts. +- A packaged guidance catalog can become stale; citation verification and + reviewed updates are required. + +### Neutral + +- The harness does not change Homecore's protocol, persistence, migration, + plugin, HAP, or voice implementation. +- A passing software profile does not establish a production deployment, + third-party ecosystem parity, Apple certification, or hardware behavior. +- Ruflo remains an optional development coordinator and is not a runtime + dependency of `homecore`. + +## Links + +- [ADR-126](ADR-126-ruview-native-ha-port-master.md) - Homecore master decision. +- [ADR-128](ADR-128-homecore-integration-plugin-system.md) - plugin boundary. +- [ADR-130](ADR-130-homecore-rest-websocket-api.md) - REST/WebSocket contract. +- [ADR-133](ADR-133-homecore-assist-ruflo.md) - assist and agent bridge. +- [ADR-161](ADR-161-homecore-server-layer-security.md) - server security. +- [ADR-165](ADR-165-homecore-migrate-from-home-assistant.md) - migration trust boundary. +- [ADR-182](ADR-182-npx-ruview-harness-via-metaharness.md) - RuView metaharness. +- [ADR-263](ADR-263-ruview-npm-harness-deep-review.md) - harness hardening. +- [ADR-265](ADR-265-ruview-npm-distribution-strategy.md) - npm distribution policy. +- [ADR-283](ADR-283-ruview-community-metaharness-flywheel.md) - shared brain and learning gates. +- `harness/homecore/` +- `v2/docs/homecore-capabilities.md` diff --git a/docs/adr/README.md b/docs/adr/README.md index f64537e6..6408d42a 100644 --- a/docs/adr/README.md +++ b/docs/adr/README.md @@ -9,7 +9,7 @@ Latest proposed decisions: - [ADR-264: Versioned wire protocol for RTL8720F CFR and Range-FFT reports](ADR-264-rtl8720f-radar-wire-protocol.md) - [ADR-263: Adopt RTL8720F 2.4 GHz FMCW radar as an optional RuView sensing platform](ADR-263-rtl8720f-2-4ghz-fmcw-radar-platform.md) -This folder contains 193 Architecture Decision Records (ADRs) that document every significant technical choice in the RuView / WiFi-DensePose project.

Its package contract is: + +```bash +npx homecore +``` + +The harness maps current capabilities to source and validation commands, +exposes a bounded MCP server, and can delegate repository exploration to a +locally installed Claude Code or Codex CLI. It does not start a home server, +change configuration, migrate data, or publish code by itself. + +## Commands + +```bash +# Source-cited overview; this is the default command. +homecore guidance +homecore guidance --topic plugins --query "Wasmtime signatures" +homecore capabilities + +# Diagnose the package, WASM kernel, local CLIs, and optional checkout. +homecore doctor --repo . +homecore wasm status --strict + +# Run focused Homecore tests in a trusted RuView checkout. +homecore verify --repo . --profile core +homecore verify --repo . --profile wasm +homecore verify --repo . --profile hap + +# Explore through a local host.

Every MCP tool is read-only; +Cargo verification remains an explicit local CLI operation and is not exposed +through MCP. MCP request size, queue depth, tool-call duration, and the total +tool-call budget of each server process are bounded. + +Repository-aware MCP calls are bound to the exact RuView checkout found when +the server starts. Launch it from that checkout, or set +`HOMECORE_TRUSTED_REPO` to its root. An MCP request cannot nominate a different +checkout as its own trust anchor. + +The packaged `.codex`, `.claude`, and generic MCP templates invoke an +already-installed `homecore` binary and never track an npm dist-tag. To print +configuration for an ephemeral installation, run `homecore install --host +codex` or `homecore install --host claude-code`; the generated `npx` +configuration pins the package's exact version. + +## WASM-first runtime + +The harness asks `@metaharness/kernel` for its packaged WebAssembly backend +before considering a native or JavaScript fallback. The kernel validates the +MCP server specification. `homecore wasm status` reports the backend that +actually loaded; `--strict` fails if it is not WASM. + +This is separate from Homecore's application plugin boundary: + +- compiled-in native plugins must be explicitly registered in the server; +- external plugin packages are bounded and signature-checked WebAssembly; +- execution through Wasmtime is feature-gated; +- arbitrary native dynamic libraries are not loaded. + +Use `homecore verify --profile wasm` to exercise the Wasmtime-specific Rust +tests in a checkout. + +## Capability honesty + +The catalog distinguishes implemented, feature-gated, provider-required, and +integration-dependent behavior. Home Assistant compatibility means the +documented core REST/WebSocket contract, not every endpoint supplied by the +Home Assistant integration ecosystem. HAP protocol tests are not Apple +certification. STT/TTS provider contracts do not imply that a deployment has a +real speech provider. + +Every guidance result cites repository paths, focused validation commands, and +known limitations. A packaged citation is navigation evidence; source, tests, +accepted ADRs, and repository policy remain authoritative. + +## Shared brain + +Reviewed records live in `brain/corpus/core.jsonl`. Search is deterministic and +local. `brain propose` prints an unreviewed JSONL candidate but never edits the +canonical corpus.
