Certify a published MeshLLM packaging release end to end across native Linux packages, Homebrew, npm SDK, and OCI images. Use when validating a MeshLLM version or packaging tag, proving that published artifacts install or load and start their packaged runtime, checking release checksums/SBOM/provenance/labels, comparing versions across channels, preserving pre-existing services, cleaning all test state, and producing an evidence-backed overall PASS/FAIL/BLOCKED verdict.

Distribution Certification
Validate the complete published MeshLLM distribution, not merely release
metadata. Install or load every required format, prove its packaged runtime
reaches a real ready state, stop it cleanly, and restore every host to its
preflight state.
Read these resources completely before acting:
references/format-checks.md for per-channel
preflight, integrity, installation, runtime, and cleanup checks.
Canonical packaging repository and immutable packaging tag.
Canonical OCI repository.
Canonical Homebrew tap/formula.
Canonical npm package name.
Remote hosts assigned to each native package platform.
Expected native/image matrix.
Use user-supplied values when present. Otherwise derive the matrix from the
tagged packaging source, never from memory or a newer branch. Do not silently
substitute a newer version, tag, repository, package scope, architecture, or
backend.
If a required host is unspecified, select only a compatible host documented in
the repository's authoritative computer inventory. Ask before using an
undocumented machine or before making a materially different substitution.
Mandatory preparation
Read the repository AGENTS.md.
Inspect release workflows, tag-generation code, live runs, and publishing
topology only through read-only source, API, and log views. Never dispatch,
rerun, cancel, publish, approve, or mutate CI.
Before recording, capturing, downloading, installing, or creating evidence,
prove the evidence paths are ignored by running a git check-ignore gate for
the root, final report, and a representative nested owner path:
for path in \
"artifacts/distribution-certification-<version>-<UTC timestamp>/" \
"artifacts/distribution-certification-<version>-<UTC timestamp>/REPORT.md" \
"artifacts/distribution-certification-<version>-<UTC timestamp>/debian/ubuntu-24.04-amd64-cpu/RESULT.md"; do
git check-ignore --quiet -- "$path" || exit 1
done
Abort immediately if any path is unignored.
Create the evidence root only after the ignore gate passes.
Record the exact certification inputs and start time before downloading or
installing anything.
Safety boundary
This skill is validation-only.
Use only already-published artifacts for the exact requested version.
Never build MeshLLM from source.
Never publish or replace assets, mutate a release, alter tags, rerun a
workflow, change secrets, or edit another repository.
Never stop, replace, reconfigure, or signal a pre-existing MeshLLM process or
service.
Never invoke a pre-existing shadowing executable accidentally.
Never use a TUI through SSH or in a container.
Start every noninteractive MeshLLM CLI with --log-format json.
Run remote smoke processes in a held foreground SSH session with a separate
observer and a separate control channel. Do not rely on detached first starts.
Use disposable, least-privileged accounts, tokens, containers, temp roots, and
remote directories. Do not forward SSH agents or mount credential-bearing
files, sockets, config directories, or host paths into containers or remotes.
Scrub credentials and sensitive environment variables before every command,
including tokens, keys, cookies, passwords, signing material, cloud variables,
GitHub variables, npm tokens, registry auth, and private endpoints.
Use unique temporary directories, API ports, console ports, container names,
cache roots, runtime roots, and log names.
Remove only state proven to have been created by the certification. Never use
broad cleanup such as docker system prune, recursive deletion of a broad
directory, or package-cache purges.
Continue independent rows after failures so the final matrix is complete.
Diagnose defects after the matrix; do not fix them during certification.
Preflight before every mutation
Capture the host OS, kernel, architecture, disk space, package-manager state,
all mesh-llm executables, exact running processes, relevant system/user
services, occupied default ports, and proposed test ports.
Also snapshot format-specific persistent state that an install hook may change:
Homebrew taps and installed formulae.
Docker versioned references and containers.
User MeshLLM cache/config/runtime paths.
Arch Snapper snapshot IDs when pacman hooks create snapshots.
If an active service or installed package would be affected, do not disturb it.
Use an isolated path only when it still proves the canonical distribution
contract. Otherwise mark the row BLOCKED with exact evidence.
Phase 1: immutable release inventory
Snapshot the packaging release before other tests:
Record release ID, tag, body, publication time, draft/prerelease flags, asset
IDs, asset creation/update times, byte sizes, URLs, and server-reported
digests.
Require the body to identify the exact upstream MeshLLM version/ref.
Resolve the packaging tag to its exact commit, including peeled annotated tag
commit when present. Verify the downloaded tag source resolves to that same
commit, re-query the remote tag before report finalization, and fail the
release if the tag moved.
Download the aggregate checksum, aggregate provenance, formula, every native
package, every package sidecar, and every expected row SBOM/upstream
provenance file.
Download each upstream MeshLLM product archive and require the product-v2
layout: one backend-neutral mesh-llm host, product-manifest.json,
host-imports.json, and exactly one selected runtime below
native-runtimes/<runtime-id>/manifest.json.
Verify every downloaded asset byte-for-byte against the server-reported
digest where the release surface provides one, then verify every native
package against both its sidecar and aggregate checksum.
Run the aggregate checksum across every file it names, not just native
packages. A stale formula or metadata checksum is a release failure.
Compare asset timestamps/digests with the release snapshot before and after
checksum verification. Reject moved tags, replaced assets, stale aggregate
checksums, and any checksum generated before the asset bytes it claims.
Download the immutable packaging tag source and derive the expected matrix
using its checked-in matrix and tag-generation code. Do not build product
code.
Confirm one SBOM and one upstream-provenance file for every enabled native
row. Cryptographically verify SBOM and provenance subjects against the exact
artifact digests they claim, and reject unrelated or stale subjects.
Explicitly record disabled/unsupported rows.
For each product archive, validate every digest recorded by
product-manifest.json, verify that the host dependency report rejects no
backend runtime imports, and confirm that the selected runtime ID, platform,
backend, and MeshLLM version match the release row. Reject absolute build paths
or additional top-level payload files.
Preserve both redacted machine-readable inventory and a concise human-readable
validation log.
Resolve the package-owned or channel-owned executable directly.
Run --version and require exact MeshLLM semantic version equality.
Run runtime list where the channel exposes the CLI.
Require runtime list to discover the channel-owned adjacent runtime while
the user cache is empty; it must not copy that runtime into the cache.
Run --version, --help, and runtime list without GPU/device passthrough.
A backend driver loader failure is a product failure.
Isolate HOME, XDG paths, cache directory, and runtime directory.
Reserve both an API port and a console port. Pass both explicitly even when
using --no-console; some versions may still initialize the web server.
Start client mode with --log-format json --no-console --auto.
Require the process/container to remain alive and emit a real ready event
such as Client ready.
Probe /v1/models only when an endpoint was intentionally exposed.
Send SIGINT, enforce a bounded shutdown, capture the final exit state, and
verify listeners/processes disappeared.
A metadata-only check, successful install, --version, or transient live PID
is not runtime certification.
For composed product-v2 channels, also record the producer schema SHA-256 and
prove it is byte-identical to the packaging consumer schema at the immutable
upstream source SHA. Group all selected product provenance records by
OS/architecture and require exactly one host SHA-256 per group before treating
backend rows as aliases of a shared host.
Phase 3: cross-channel consistency
Require agreement on the requested semantic version across:
packaging tag and release body;
normalized native package versions (distro revision suffixes such as -1
are allowed only when upstream version remains exact);
package-owned executables;
Homebrew formula, Cellar version, and exact Cellar executable;
npm package and currentMeshVersion();
OCI labels, installed in-image package metadata, and every loadable image
executable.
Also prove:
Native packages own the expected executable path.
Native packages own the versioned runtime tree and product manifests; the
host remains backend-neutral and no package installs backend libraries beside
the executable.
Images install their native package rather than copying an unrelated binary.
Homebrew installs the host plus the matching runtime under libexec from the
expected upstream Apple Silicon product archive.
npm selects the current host's advertised prebuilt addon.
No test invokes a shadowing user-local executable.
No channel resolves to an older release.
An executable that cannot load does not satisfy version consistency even if its
metadata says the right version.
Phase 4: cleanup audit
Perform cleanup in a finally/trap path for every mutable test.
After all channel owners finish, independently recheck:
original package/formula/tap state;
exact process and listener absence;
test directory/cache/runtime absence;
Docker container and image-reference restoration;
remote temp-directory absence;
preservation of every pre-existing service, executable, image, and user
state.
Record a final UTC cleanup transcript. Do not claim cleanup from an attempted
command alone; verify the resulting state.
Use references/report-contract.md. The report
must contain a row for every required native, Homebrew, npm, and image target,
plus release inventory. Include exact failures, commands, exit codes, log
excerpts, checksums, digests, readiness, pre-existing conflicts, and cleanup.
Delegated owners write only RESULT.md under their evidence directory. Each
RESULT.md must contain exactly these mandatory fields:
The orchestrator owns release inventory, cross-channel consistency, independent
cleanup verification, and the centralized REPORT.md.
Verdict precedence:
FAIL if any required published artifact is missing, corrupt, mislabeled,
uninstallable, unloadable, version-inconsistent, or cannot reach readiness.
Otherwise BLOCKED if environmental safety or unavailable infrastructure
prevents any required row.
PASS only when every required row passes and cleanup is verified.
Rows that are intentionally metadata-only use NOT APPLICABLE for runtime
columns, not PASS.
Findings-driven guardrails
Always preserve these learned checks:
Detect release assets replaced after aggregate checksum generation.
Run remote smoke processes in a held foreground TTY with a separate observer
and control channel; do not rely on detached SSH first attempts.
Treat --no-console as insufficient isolation by itself; reserve/pass a
unique console port too.
Redact ephemeral invite tokens without deleting readiness, status, signal,
exit, and listener evidence.
Run npm harnesses from inside the fresh project so Node resolves the installed
package rather than the evidence script's directory.
For OCI indexes, accept expected platform children plus unknown/unknown
attestation manifests. Resolve the index digest from a trustworthy inspect
surface; do not mark an image failed because a log wrapper made raw JSON
unparsable.
Pull every image with explicit platform and confirm local OS/architecture.
Run CUDA client images without device passthrough. A hard
libcuda.so.1 loader dependency is a product failure, not an environmental
skip.
Record and remove only test-created Arch package-manager snapshots.
