Success = the new Lint items appear in the audit op, the citations are present, and `node scripts/ci.mjs` is green (content hashes re-synced). + +## Context & rationale + +- **Why citation, not adoption (the gate):** the investigation found `claude-mega-brain` (MIT) is architecture-mismatched (its value is a Claude hook + a homegrown `type:` convention docks doesn't ship), OKF (Apache-2.0) is a *data-asset* metadata format with no OKF-aware consumer in docks and would collide with the agentskills.io schema, and the Karpathy gist is **unlicensed** (all-rights-reserved) so its prose can't be vendored. All three are convergent descendants of the same LLM-Wiki pattern docks already implements. Therefore the correct, proportionate action is a citation + borrowing one uncopyrightable idea — not importing schema, files, or a dependency. +- **Why the Lint checklist is the additive slice:** docks' `context-tree audit` already checks "AGENTS.md claims that no longer match current source." Karpathy's Lint adds checks docks lacks: **contradictions between nodes, orphan nodes (no inbound links), concepts mentioned but lacking their own node, missing cross-references, and web-fillable data gaps.** These map cleanly onto the existing read-only audit. +- **docks already cites Karpathy** (`capability-tuning` — "Grounded in context engineering (Karpathy's method)"), so this extends an acknowledged lineage rather than introducing a new dependency. + +## Environment & how-to-run + +- **Setup:** `corepack enable && pnpm install --frozen-lockfile` (once). +- **Gate:** `node scripts/ci.mjs` — must be green; it includes the `skill content_hash in sync` check, so any SKILL.md prose change requires re-syncing `metadata.content_hash` + bumping `metadata.updated`. +- **Content-hash re-sync:** run `node scripts/skills/content-hash.mjs --backfill` — it recomputes each skill's `content_hash` from its body **plus its sorted `references/*.md`**, so editing a reference file re-drives the OWNING SKILL.md's hash even if the body was untouched. Bump `metadata.updated` per the `skill-maintenance` procedure.

"Replace" means the five `.mjs` are **deleted** and every manifest/hook/test path resolves to `${CLAUDE_PLUGIN_ROOT}/bin/relay`. The port also (a) upgrades the cross-process store lock from a hand-rolled mkdir-mutex + stale-reclaim to a **kernel-managed `flock`** (auto-released on crash), and (b) cuts per-`Write` hook cold-start from ~20–60 ms (Node) to ~1–5 ms (native). Success = both tools launch the bus/hook/CLI from `bin/relay`, every existing security/self-test invariant still passes, all four arch binaries are committed, and `node scripts/ci.mjs` is green. + +**Why now / why Rust (decision rationale):** A prior multi-language analysis (this branch) concluded a compiled binary is the *only* option that removes the consumer runtime dependency — Python/uv only grows it. Rust was chosen over Go for the smaller committed artifact (binaries live in git), no-GC purity, ecosystem alignment with Codex (itself Rust), and being the more correct home for the concurrency-critical store. macOS was verified a **non-issue** for this git-clone-delivered CLI: native `macos-14`/`macos-13` runners build darwin with zero cross-toolchain, and Gatekeeper/notarization never fires on a git-cloned (non-quarantined) binary. Scope (**commit binaries in-tree**, full 5-file port) was chosen by the maintainer over download-on-first-run. + +## Context & rationale + +- **Why one binary, not per-file:** the flock upgrade is **all-or-nothing**. `~/.agent-relay` is a store shared by the bus, the hook, and the CLI; `flock` only interlocks with other `flock` callers and Node has no stable `flock`. If any store toucher stays Node (mkdir-mutex), mutual exclusion silently breaks. Collapsing the 3 process entry points + 2 library modules into one executable guarantees every toucher shares one lock implementation by construction — which is also why the 5 `.mjs` must be **deleted**, not left as orphaned Node store touchers. +- **Entry points → subcommands:** `mcp/bus.mjs` → `relay bus`; `hooks/session-start.mjs` (argv `codex` tag) → `relay hook [codex]`; `skills/.../scripts/relay.mjs` (already subcommand-shaped) → `relay discover|list|register|send|inbox|wake`. `lib/store.mjs` + `lib/discover.mjs` are `import`ed modules today → internal Rust modules `store.rs` / `discover.rs`. The `bus.mjs:111,130` hint strings (they point users at the relay CLI) move into `bus.rs`/`cli.rs`, not the deleted `bus.mjs`. +- **Who builds the darwin binaries (resolved decision):** `release.mjs` runs on the maintainer's **Linux** host and **cannot** cross-compile `*-apple-darwin` (the plan deliberately avoids osxcross). Therefore the four arch binaries are produced by a dedicated **GitHub Actions build matrix** on native runners (`build-binaries.yml`), downloaded as artifacts, and **committed into `bin/` before the release tag is cut**. `release.mjs` does **not** build darwin — it *asserts* the four committed binaries exist and their `SHA256SUMS` verify, then version-bumps + tags. For the first release, the download-artifacts→commit step is **manual**; automating it (a bot commit) is a noted follow-up. +- **CI provisioning (resolved decision):** because step 5 wires `cargo build` (host leg only) into `ci.mjs`, and `.github/AGENTS.md` doctrine is "ci.yml runs ci.mjs → cannot drift," the `validate` job in `ci.yml` **must** gain a Rust-provisioning step (SHA-pinned toolchain action + `rustup target add ` + `apt-get install musl-tools`). `ci.mjs` builds only the host-arch leg for the self-test and verifies the committed binaries' checksums; it never builds darwin. +- **Out-of-plugin, deferred:** `plugins/docks/hooks/context-tree-nudge.mjs` is a *different* plugin, store-less, no flock coupling — leave it Node; a `plugins/docks/bin/ctnudge` port is a separate follow-up plan (folding it in would cross the plugin boundary). +- **Pre-existing bug this plan also fixes:** `.github/workflows/ci.yml` triggers tag-CI only on `docks--v*` (line 14); session-relay tags are `session-relay--v*`, so `release.mjs`'s tag-CI wait finds no run and errors. Session-relay releases are un-gated today. Fixing it (step 1) also unblocks `build-binaries.yml` from ever running on a session-relay tag. + +## Environment & how-to-run + +- **Toolchain:** Node 24.x + pnpm (`corepack enable`) for the existing gate; **Rust** (edition 2024, MSRV ≥ 1.85) with `cargo`. `rustup target add x86_64-unknown-linux-musl aarch64-unknown-linux-musl x86_64-apple-darwin aarch64-apple-darwin`. The Linux aarch64-musl leg needs `musl-tools` + an aarch64 cross-linker (or `cross`); **darwin legs build natively on `macos-14`/`macos-13` runners only** (never on the Linux host). +- **Setup:** `corepack enable && pnpm install --frozen-lockfile` (once). +- **Local gate:** `node scripts/ci.mjs` — builds ONLY the host-arch `relay` leg + runs the self-test against it + verifies committed binary checksums.

If any store toucher stays Node (mkdir-mutex), mutual exclusion silently breaks. Collapsing the 3 process entry points + 2 library modules into one executable guarantees every toucher shares one lock implementation by construction — which is also why the 5 `.mjs` must be **deleted**, not left as orphaned Node store touchers. - **Entry points → subcommands:** `mcp/bus.mjs` → `relay bus`; `hooks/session-start.mjs` (argv `codex` tag) → `relay hook [codex]`; `skills/.../scripts/relay.mjs` (already subcommand-shaped) → `relay discover|list|register|send|inbox|wake`. `lib/store.mjs` + `lib/discover.mjs` are `import`ed modules today → internal Rust modules `store.rs` / `discover.rs`. The `bus.mjs:111,130` hint strings (they point users at the relay CLI) move into `bus.rs`/`cli.rs`, not the deleted `bus.mjs`. -- **Who builds the darwin binaries (resolved decision):** `release.mjs` runs on the maintainer's **Linux** host and **cannot** cross-compile `*-apple-darwin` (the plan deliberately avoids osxcross). Therefore the four arch binaries are produced by a dedicated **GitHub Actions build matrix** on native runners (`build-binaries.yml`), downloaded as artifacts, and **committed into `bin/` before the release tag is cut**. `release.mjs` does **not** build darwin — it *asserts* the four committed binaries exist and their `SHA256SUMS` verify, then version-bumps + tags. For the first release, the download-artifacts→commit step is **manual**; automating it (a bot commit) is a noted follow-up. +- **Why binaries are committed in-tree, not shipped as Release assets (delivery model):** the whole point is "every consumer, Codex or Claude, works just by installing." Plugins are delivered by **git clone** (marketplace → local cache); `${CLAUDE_PLUGIN_ROOT}` resolves to that cloned tree. A GitHub **Release asset is never cloned**, so a consumer would get a plugin with no binary. Therefore the four arch binaries MUST live in `plugins/session-relay/bin/` **inside the tagged commit**. `gh release create` (which `release.mjs` runs) is only the human-facing changelog — not a delivery channel. +- **Chicken-and-egg this forces:** `release.mjs` tags `HEAD`, and that tag push **is** the CI gate. So the binaries must already be in `HEAD` when `release.mjs` runs — they **cannot** be produced by the tag-triggered CI (it fires *after* the tag exists). Order is forced: build (pre-tag) → commit into `bin/` → `release.mjs` bumps + tags + gates. Hence `build-binaries.yml` runs on `workflow_dispatch` (pre-release), never on the tag. +- **Who builds the four binaries — CI canonical + Mac fallback (resolved decision):** darwin needs a genuine Apple SDK (no osxcross; `cross`/Docker cannot target macOS), so the **Linux host can only make the 2 musl arches, never darwin**. The **canonical** producer is a **GitHub Actions matrix** (`build-binaries.yml`: `macos-14`→aarch64-darwin, `macos-13`→x86_64-darwin, `ubuntu`→both musl) — it decouples "cut a release" from being at a Mac and always builds darwin on real Apple hardware. A **local fallback script** (`rust/build-all.sh`) reproduces all four **from an Apple-Silicon Mac** (arm64-darwin native + x86_64-darwin via `rustup target add` + both musl via `cross`/Docker), for when the maintainer wants to build straight from the MacBook. Either path: download/produce the four + `SHA256SUMS`, **commit into `bin/` before tagging**; `release.mjs` does **not** build darwin — it *asserts* all four exist and `sha256sum -c` passes, then version-bumps + tags. First-cut artifact→commit is **manual**; a bot-commit automation is a follow-up. - **CI provisioning (resolved decision):** because step 5 wires `cargo build` (host leg only) into `ci.mjs`, and `.github/AGENTS.md` doctrine is "ci.yml runs ci.mjs → cannot drift," the `validate` job in `ci.yml` **must** gain a Rust-provisioning step (SHA-pinned toolchain action + `rustup target add ` + `apt-get install musl-tools`). `ci.mjs` builds only the host-arch leg for the self-test and verifies the committed binaries' checksums; it never builds darwin. - **Out-of-plugin, deferred:** `plugins/docks/hooks/context-tree-nudge.mjs` is a *different* plugin, store-less, no flock coupling — leave it Node; a `plugins/docks/bin/ctnudge` port is a separate follow-up plan (folding it in would cross the plugin boundary). -- **Pre-existing bug this plan also fixes:** `.github/workflows/ci.yml` triggers tag-CI only on `docks--v*` (line 14); session-relay tags are `session-relay--v*`, so `release.mjs`'s tag-CI wait finds no run and errors.

Plugins are delivered by **git clone** (marketplace → local cache); `${CLAUDE_PLUGIN_ROOT}` resolves to that cloned tree. A GitHub **Release asset is never cloned**, so a consumer would get a plugin with no binary. Therefore the four arch binaries MUST live in `plugins/session-relay/bin/` **inside the tagged commit**. `gh release create` (which `release.mjs` runs) is only the human-facing changelog — not a delivery channel. - **Chicken-and-egg this forces:** `release.mjs` tags `HEAD`, and that tag push **is** the CI gate. So the binaries must already be in `HEAD` when `release.mjs` runs — they **cannot** be produced by the tag-triggered CI (it fires *after* the tag exists). Order is forced: build (pre-tag) → commit into `bin/` → `release.mjs` bumps + tags + gates.

A **local fallback script** (`rust/build-all.sh`) reproduces all four **from an Apple-Silicon Mac** (arm64-darwin native + x86_64-darwin via `rustup target add` + both musl via `cross`/Docker), for when the maintainer wants to build straight from the MacBook. Either path: download/produce the four + `SHA256SUMS`, **commit into `bin/` before tagging**; `release.mjs` does **not** build darwin — it *asserts* all four exist and `sha256sum -c` passes, then version-bumps + tags.

The producer is a **GitHub Actions matrix** (`build-binaries.yml`), free+unlimited on public repos ([GitHub-hosted runners reference](https://docs.github.com/en/actions/reference/runners/github-hosted-runners)): **one Apple-Silicon `macos-latest` (arm64) runner builds BOTH darwin arches** — `aarch64-apple-darwin` native + `x86_64-apple-darwin` via `rustup target add` (Apple's universal SDK cross-compiles Intel from Apple Silicon) — plus **one `ubuntu-latest`** for both linux-musl arches. Four binaries, two free runners. (`macos-13`, the old Intel image, was **retired**; Intel is now `macos-*-intel` — but we don't need an Intel runner since arm64 cross-builds the Intel-darwin leg.) Download the four artifacts + `SHA256SUMS`, **commit into `bin/` before tagging**; `release.mjs` does **not** build darwin — it *asserts* all four exist and `sha256sum -c` passes, then version-bumps + tags. First-cut artifact→commit is **manual**; a bot-commit automation is a follow-up. +- **No local "build-all" second path (decision — why not a Mac script):** a committed `build-all.sh` maintained in lockstep with the workflow would be a duplicate build system (drift risk + env variance vs the controlled CI runner) for zero benefit toward "every consumer just installs it" — CI already produces all four. Developing from the MacBook needs only the **host leg** (`ci.mjs` builds `aarch64-apple-darwin` natively). Producing all four locally is *possible* (the four `cargo build --target …` commands, darwin native+cross on the Mac, musl via `cross`) and documented as an optional escape hatch, but is not a maintained artifact. - **CI provisioning (resolved decision):** because step 5 wires `cargo build` (host leg only) into `ci.mjs`, and `.github/AGENTS.md` doctrine is "ci.yml runs ci.mjs → cannot drift," the `validate` job in `ci.yml` **must** gain a Rust-provisioning step (SHA-pinned toolchain action + `rustup target add ` + `apt-get install musl-tools`). `ci.mjs` builds only the host-arch leg for the self-test and verifies the committed binaries' checksums; it never builds darwin. - **Out-of-plugin, deferred:** `plugins/docks/hooks/context-tree-nudge.mjs` is a *different* plugin, store-less, no flock coupling — leave it Node; a `plugins/docks/bin/ctnudge` port is a separate follow-up plan (folding it in would cross the plugin boundary). - **Pre-existing bug this plan also fixes:** `.github/workflows/ci.yml` triggers tag-CI only on `docks--v*` (line 14); session-relay tags are `session-relay--v*`, so `release.mjs`'s tag-CI wait finds no run and errors. Session-relay releases are un-gated today. Fixing it (step 1) makes the `validate` workflow run on a session-relay tag, so `release.mjs`'s tag-CI wait resolves and the release is actually gated. ## Environment & how-to-run -- **Toolchain:** Node 24.x + pnpm (`corepack enable`) for the existing gate; **Rust** (edition 2024, MSRV ≥ 1.85) with `cargo`. `rustup target add x86_64-unknown-linux-musl aarch64-unknown-linux-musl x86_64-apple-darwin aarch64-apple-darwin`.

The port also (a) upgrades the cross-process store lock from a hand-rolled mkdir-mutex + stale-reclaim to a **kernel-managed `flock`** (auto-released on crash), and (b) cuts per-`Write` hook cold-start from ~20–60 ms (Node) to ~1–5 ms (native). Success = both tools launch the bus/hook/CLI from `bin/relay`, every existing security/self-test invariant still passes, all four arch binaries are committed, and `node scripts/ci.mjs` is green. **Why now / why Rust (decision rationale):** A prior multi-language analysis (this branch) concluded a compiled binary is the *only* option that removes the consumer runtime dependency — Python/uv only grows it. Rust was chosen over Go for the smaller committed artifact (binaries live in git), no-GC purity, ecosystem alignment with Codex (itself Rust), and being the more correct home for the concurrency-critical store. macOS was verified a **non-issue** for this git-clone-delivered CLI: a free Apple-Silicon `macos-latest` runner builds both darwin arches with zero cross-toolchain (arm64 native + x86_64 via the added target), and Gatekeeper/notarization never fires on a git-cloned (non-quarantined) binary.

Toolchain pinned via rust-toolchain.toml (1.85.0 + rustfmt/clippy). cargo test: 7/7 — incl. an 8-worker x 10-op cross-process race (80 untorn unique mailbox lines, 88 registry entries = zero lost RMW) and the .lock dir->file migration test. fmt --check clean; clippy -D warnings clean.
