📝 WalkthroughWalkthroughThe PR adds scope locks and repair envelopes to the PR follow-up lifecycle, enforces them before repair commits, and adds evaluations for permitted and oversized repairs. ChangesRepair scope control
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to The workflow can still publish changes outside the locked repair scope through edits to existing unpermitted paths or validator-generated diffs. The enforcement and its evaluation fixtures should be corrected before merge. Sequence Diagram(s)sequenceDiagram

92-92: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick winReapply the envelope check to validator-created changes.
Line 92 allows a tracked diff produced by
npm run validate:prto be committed after inspection. It does not require the path, file-count, line-churn, and semantic-scope checks required before the repair commit at Lines 69-70. A validator or formatter can therefore add out-of-scope changes after the last envelope check. Re-run the complete scope comparison before committing that diff, or discard it when it exceeds the lock.🤖 Prompt for AI Agents

Make the scope-lock fixtures explicit.
The positive case names a workflow and test-file shape, and the adversarial case names a “focused PR,” but neither provides the recorded permitted path set and complete repair envelope. The evaluator cannot derive exact path and budget decisions from those labels alone. Include exact paths, maximum additional files, and maximum churn, or state that the harness injects this record.

Check the complete repair path delta against the allowlist.
Line 47 records permitted paths, but Lines 48-49 require only “all new paths” to fit. A repair can modify or delete an existing path outside the envelope and remain within the file and line budgets. Compare every path changed by the returned repair delta with permitted paths before Lines 69-70 create the commit. Add an evaluation for an in-budget change to an unpermitted existing path.

Outcome
PR repair workflows now freeze the accepted behavior and diff baseline before review collection. A valid review finding can proceed only inside a predeclared path and churn envelope; wider repairs stop before commit or push pending an explicit scope decision.
Reason
PR #10898 added stable-candidate review collection and new-scope classification, but it did not bind a returned repair to measurable limits. During PR #10829, review suggestions expanded a reduced candidate from about 300 changed lines to about 2,000 because the agent treated each suggested remedy as authorized scope.
