# Text Redline Workbench & Diff Receipt

`POST /v1/tools/build_redline_diff_receipt`

## Request

- Base URL: `https://ainumbers.co`
- URL: `https://ainumbers.co/v1/tools/build_redline_diff_receipt`
- Auth: none declared

Deterministic line-level redline between an original and revised text or markdown document, with a cryptographic diff receipt (original/revised digests, diff-algorithm identifier, per-hunk digests, reviewer key, eddsa signature) and a hash-chained per-hunk accept/reject/comment disposition chain binding a replayable accepted-text digest. Built-in verifier recomputes the redline from a pasted receipt bundle and flags the exact hunk on any divergence. Paste-mode. Zero egress. Zero PII.

**Tool URL:** https://ainumbers.co/tools/552-text-redline-workbench.html
**AP2/Policy Mandate export:** yes
