Slate v2 Batch 5: Maintainer / Diff / Migration Story

Goal

Execute Batch 5 from docs/slate-v2/master-roadmap.md.

Phases

1. De-noise the file-review ledger
2. Refresh the maintainer diff register
3. Align the migration story across roadmap, ledger, and diff register
4. Re-check architecture-contract truth labeling
5. Verify and review

Progress

• started Batch 5 execution
• expanded the release-file-review ledger beyond docs-only rows so it now tracks:
  • repo-local envelope docs
  • replacement command graph buckets
  • contributor-facing recovery buckets
  • direct proof surfaces
• refreshed the maintainer diff register with:
  • maintainer reading order
  • migration rules
  • freeze read
  • whole-worktree snapshot warning on raw diff counts
• aligned docs/slate-browser/overview.md with the migration-review rule
• removed agent-skill path leakage from architecture-contract.md

Exit Read

Batch 5 is complete.

The maintainer story is no longer split across implied context and stale plans.

Risks

• the ledger can easily turn into fake checkbox sludge
• the maintainer story can drift if the register and roadmap stop using the same vocabulary
