+- [Packaging releases](https://github.com/Mesh-LLM/mesh-packaging/releases/latest)
+  contain the versioned `.deb` and `.pkg.tar.zst` files, checksum sidecars,
+  aggregate `SHA256SUMS`, SPDX SBOMs, provenance records, and the Apple Silicon
+  Homebrew formula.
+- [GHCR](https://github.com/orgs/Mesh-LLM/packages/container/package/mesh-llm)
+  contains public CPU, Vulkan, CUDA, and ROCm runtime images. See
+  [`docs/tagging.md`](docs/tagging.md) for immutable and moving tag names.
+
+Package-manager repositories and a public Homebrew tap are not published. The
+native packages and formula are directly downloadable GitHub Release assets.

 ## Automation
 
 `.github/workflows/images-release.yml` accepts the `mesh-llm-release` repository dispatch event and safe manual backfills. Every manual run defaults to `dry_run=true`. Dry-run mode forces both publish switches off while still downloading, checksumming, packaging, installing, image-building, and Homebrew-testing the selected rows.

 # Production Readiness TODO
 
+- [x] Replace former `Mesh-LLM/mesh-agent-images` repository references after
+  the repository rename. QA: `rg -n 'mesh-agent-images' --glob '!TODO.md' .`
+  returns no matches, `scripts/image-matrix.ts validate` passes, and all 12
+  TypeScript tests pass locally.
+
+- [x] Publish a flat, self-consistent aggregate checksum manifest. QA: the
+  release staging simulation rejects basename collisions and its generated
+  `SHA256SUMS` passes `sha256sum -c`; the live `packaging-v0.73.1` manifest
+  exactly matches all 46 non-manifest GitHub asset digests, does not hash
+  itself, and workflow lint passes locally.
+
+- [x] Keep the rendered Homebrew formula acceptable to Homebrew's style and
+  install checks. QA: Homebrew release unit tests pass, `brew style` accepts the
+  rendered formula, and the formula installs and tests on Apple Silicon.
+
 The current packaging and image pipeline is functional, but production readiness
 requires broader validation, supply-chain hardening, and a final publishing
 strategy.
