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.
