The mis-anchor pathology anchor-snap repairs downstream (reviewers counting unified-diff text lines instead of file lines) exists because the staged diff makes the model count; the staging now prints the real number on every content line so anchors are read off the page, never counted. A new deterministic `annotateDiffLineNumbers` (`lib/diff.ts`) prefixes each hunk content line with its line number (`+`/context lines carry the NEW-file RIGHT-side number, `-` lines the OLD-file LEFT-side number) while keeping the diff marker in column one, so annotated text still splits into file sections. The provenance CLI writes `full-stripped-annotated.diff` beside the raw stripped diff, and a new `annotate ` subcommand produces `pr-annotated.diff` after Phase 1 builds `pr.diff` (the scoped and flip-gated depths refresh the annotated copies the same way). Every finding-producing reviewer (correctness, skill-auditor, conventions, the four whole-change reviewers, and all eleven specialist lenses via the shared disciplines block) now reads the annotated copy, takes `anchor.line` from the printed number, and strips the prefix when quoting code or authoring a `suggested_patch`. Everything that PARSES a diff keeps reading the raw files: provenance, re-review hunk fingerprints (whose signatures must not shift), scoped staging, and pattern-triage/claim-validator are untouched. The eval stages the annotated siblings for both arms unconditionally, and only a review.md version that names them reads them, so the A/B against a pre-annotation baseline is a pure prompt delta with no staging flag. The measurement instrument rides along: per-case anchor-snap counts (`perCase.snapped`) in the arm report and a pooled "Findings anchor-snapped" row in the aggregate, version-tolerant of older artifacts — if annotation works, candidate-arm snaps fall to zero because anchors arrive correct, with the anchor-snap gate remaining as the deterministic backstop. diff --git a/workflows/review/eval/README.md b/workflows/review/eval/README.md index 26c17276..16b62ab8 100644 --- a/workflows/review/eval/README.md +++ b/workflows/review/eval/README.md @@ -130,7 +130,14 @@ reviewer, was wrong). prompts carry the rule, both arms snap and the A/B is back to measuring prompt deltas alone.
