kingwl 0a486f09c9 chore: adopt node-addon-landlock-run source as native/ subtree
Bring the node-addon-landlock-run tree (tag v0.0.1, commit 614f7fd) into
native/landlock-run as its source of record: launcher development happens
here, next to the harness consumers, and the standalone repository becomes
the release mirror the tree is exported to for packing and publishing
(procedure in native/README.md). The subtree keeps its own pnpm workspace
and lockfile and is NOT added to the harness workspace: harness installs,
gates, and CI never touch it. The mirror's .github/ stays out of the
subtree; a separate manually-dispatched workflow
(.github/workflows/landlock-run.yml) runs the subtree's CI legs — the
per-architecture native builds, real-kernel launcher proofs, and pack
rehearsal — adapted with working-directory/cache paths.

eslint ignores the subtree like vendor/; AGENTS.md gains the native/
layout line (+5 words on its budget ceiling).

node-addon-landlock-run

Landlock self-restrict-then-exec launcher for confining subprocesses on Linux: this entry package resolves the per-platform prebuilt binary, runs its functional enforcement probe, and builds its grant argv — consumers never spell launcher flags or parse launcher output themselves.

import { grantArgs, launcherPath, probe } from 'node-addon-landlock-run';

const launcher = launcherPath();
if (probe(launcher) !== 'unusable') {
  const argv = [launcher, ...grantArgs({ readOnly: ['/'], readWrite: ['/tmp/work'] }), '--', 'bash', '-c', command];
}

The launcher installs a Landlock ruleset on itself and execs the wrapped command; the ruleset is inherited across execve, so the whole process tree runs confined. Everything not granted is denied, and launcher failures exit 125 without running the command — fail-closed, never fail-open. The binary contract is pinned in the repo's docs/cli-contract.md; the C source rides this tarball (src/main.c) for audit.

Platform packages (os/cpu-selected optional dependencies, no JavaScript inside): node-addon-landlock-run-linux-x64, node-addon-landlock-run-linux-arm64. On hosts without one, launcherPath() returns a deterministic nonexistent path and probe() reports 'unusable' — there is deliberately no install-time compile fallback.
