## Description

Use when the user provides an original and rewritten version, asks whether a rewrite preserved protected content, or wants a deterministic check for code, frontmatter, quotes, tables, links, paths, numbers, headings, and residual AI-pattern regressions.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Preservation Verifier

Verify that a rewrite or file edit kept the content the original `../avoid-ai-writing/SKILL.md` says to protect.

For cross-Skill work, follow `../avoid-ai-writing-router/references/handoff-contract.md` and `../avoid-ai-writing-router/references/skill-graph.json`.

## Connection contract

### Incoming

Accept before/after verification from:

- `avoid-ai-writing-router` via `ROUTE` when the user directly supplies before and after material.
- `voice-preserving-rewriter` via `VERIFY` after returned-text rewriting.
- `file-edit-in-place` via `VERIFY` after an authorized named-file mutation.

Require both original and current versions. If either is unavailable, return control to the router rather than inventing a comparison.

### Produce

Update the handoff envelope with:

- `execution_evidence.verifier`: `executed` only if the bundled validator ran, otherwise `model_only`.
- `verification_summary.status`: `PASS`, `REVIEW`, or `FAIL`.
- blocking errors and warnings.
- exact repair target when repair is possible.

A `FAIL` is a blocking workflow result. The rewrite/edit stage is not complete merely because text was produced or a file write succeeded.

### Outgoing

- `REPAIR` to `voice-preserving-rewriter` when returned text failed preservation and the shared editing budget has room.
- `REPAIR` to `file-edit-in-place` when a named file failed preservation and the shared editing budget has room.
- `RECHECK` to `ai-writing-detector` only when convergence or a residual audit was part of the user's request.
- Stop on `PASS` unless another user-requested stage remains.
- Stop and report on a second verification failure. Do not start another repair loop.
