Slate v2 Ledger Gap Audit

Goal

Audit whether release-file-review-ledger.md actually meets the claimed “single live answer” and the stricter 1:1 legacy-file bar.

Findings

• the original audit was right: the old control ledger alone was not enough
• the repo now has exact 1:1 ledgers for every legacy file in:
  • packages/slate/test/**
  • packages/slate-react/test/**
  • packages/slate-history/test/**
  • playwright/integration/examples/**
• all four exact ledgers are now zero needs-triage
• the last core rows closed through:
  • recovered current proof in transaction-contract.ts and normalization-contract.ts
  • explicit skip for retired batch-matrix and perf harness plumbing
  • concrete engine fixes in draft-helpers.ts and create-editor.ts

Hard Read

• The old audit problem is closed.
• The exact-ledger story is now honest locally.
• The remaining no-regression debt is external browser/input evidence and final verdict cleanup, not missing legacy file rows.
