Package releases repeatedly invalidated dependency layers, retained compressed packages in image layers, and re-uploaded a combined release artifact before publication. This change keeps stable dependency stages cached, installs the exact package through a temporary mount, and reconstructs publication inputs from verified original artifact IDs and hashes.

Debian and Arch builders now use the immutable upstream commit timestamp. Canonical/mirrored base validation preserves digest identity; the mirror flag remains disabled. A bounded metrics workflow stores run/attempt/job/step history on a separate ci-metrics branch, retaining known artifact metadata after deletion and separating queue time, execution, reruns, and image families. It starts collecting after merge and never changes runner placement.

Validation: Packaging Precheck passed at 30b4ff8, including real Docker reproducibility/cache tests. The complete TypeScript suite passes, the matrix has 100% line/branch/function coverage, and actionlint/ShellCheck pass. Separate real Docker tests verify deterministic Debian/Arch builds, dependency-cache reuse, package installation, and archive absence in every image layer. Twenty-five metrics tests and live reads from packaging, MeshLLM, and runner-image runs pass. A published ARM64 CUDA 13 product also passed the MeshLLM composition/readiness path in the pinned CPU image with unchanged host/runtime hashes.

Review follow-up found and repaired an NCCL hold conflict in NVIDIA CUDA 12 runtime bases. The full v0.75.1 packaging dry run 34186128249 passed at 014cecf: 41 successful jobs, all 11 native package/image rows, Homebrew, Node SDK installation, release evidence, and final readiness. All publication jobs were skipped. The protected publication handoff and MeshLLM shared-UI release canary remain pending; no measured release-wide speedup is claimed. See docs/release-efficiency-validation.md for exact source identities and validation limits. CUDA compilation remains on the existing ARC placement. No provider flags or publication settings were changed.

Companion MeshLLM release UI and composition changes: Mesh-LLM/mesh-llm#1684.

📝 Walkthrough

Walkthrough

The change adds reproducible native packaging, dependency-stage caching, exact package installation, digest-bound image planning, original-artifact release handoffs, and historical CI metrics collection. It also adds workflow validation, integration tests, and documentation for these paths.

Changes

Packaging and release pipeline

Layer / File(s) Summary
Reproducible package and image builds
docker/*, packaging/native/*, .github/workflows/package-image-row.yml, .github/workflows/images-precheck.yml, tests/package-build-efficiency.test.ts, docs/native-packages.md
Builds require SOURCE_DATE_EPOCH, dependency stages use stable cache keys, runtime images install the exact package file, and Docker tests verify deterministic packages and package-layer omission.
Base identity and release handoff validation
.github/workflows/images-release.yml, scripts/image-base-plan.ts, scripts/release-handoff.ts, tests/image-base-plan.test.ts, tests/release-evidence.test.ts, tests/release-workflow.test.ts
Image plans validate canonical and mirrored base references. Release publication uses a small manifest and reconstructs output from original artifacts.
CI metrics normalization, collection, and reporting
scripts/ci-metrics*.ts, .github/workflows/ci-metrics.yml, tests/ci-metrics.test.ts, docs/ci-metrics.md
The metrics system normalizes GitHub data, preserves artifact history, computes cohort timing statistics, generates reports, and persists records on the ci-metrics branch.
Workflow validation and operational documentation
README.md, TODO.md, docs/publishing.md, docs/release-efficiency-validation.md, docs/runner-capacity.md, scripts/file-digest.ts, scripts/release-evidence.ts, scripts/release-index.ts, scripts/verify-sbom-subject.ts
Documentation, shared digest handling, readiness records, and workflow tests describe the updated packaging, publication, runner, and metrics behavior.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: ⚪ Minimal · up to 12214

This change improves package reproducibility, dependency caching, release-input verification, and CI metrics retention. Current validation indicates no actionable merge-blocking risk.
