This initial sc-2002 delivery measures whether native correctness-review tasks receive the source lines needed to judge a candidate. It separates source/control qualification from initial evidence coverage, so a mined finding or a filename in the inventory cannot become a verified benchmark hit.

The opt-in private-source CLI reuses native selection, task planning and evidence rendering. It pins an immutable staged tree, verifies the explicit base, archived diff and required source spans; preserves family links and uncertainty; and publishes only aliases, categories, counts and hashes. Native diagnostics are captured privately. No production reviewer, scorer, corpus or accepted checkpoint changes. The shared benchmark planner accepts an already captured native diff; existing callers retain their behavior. Generated dashboards mark the previous correctness checkpoint stale because the runner identity changed; its recorded scores are preserved.

The source investigation retains one exposed two-member diagnostic family, with a reproduced command regression and narrowly derived repair. Each version plans 11 chunks / 34 tasks. Two required caller/handler spans are absent from initial evidence, including the whole-diff contracts task. Other claims remain unresolved: zero qualified clean pairs and zero corpus admissions. Three other investigated families have explicit exclusions. Qualified independent family acquisition remains necessary before sc-2832's measured history comparison.

Validation: 22 focused census tests and 9 existing planner tests pass; the final configuration change additionally passes all 4 census/CLI tests, including the added regression, including an index-change-and-restoration regression, native size cases, span/cap boundaries, family identity and private CLI behavior. The final manifest regression rerun passes 6/6. Benchmark corpus, tracker and benchmark typecheck pass; strict manifest/visibility core typecheck passes. Broader wrapper typing traverses pre-existing untyped decisions benchmark modules; this is not full strict coverage of that dependency tree.

The full local suite was interrupted after more than 40 minutes (exit 130) after reporting failures in unchanged receipt-resume and review-event integration tests. It is failed and incomplete; no full-suite pass is claimed. PR600's CI baseline also failed: 19 failures / 6,690 passes across four failing files, including existing Git author identity and Bash resume telemetry-helper failures. Baseline CI: https://github.com/norvalbv/devkit/actions/runs/33989612695 . Existing identity ticket: https://app.shortcut.com/benordlabs/story/2410 ; resume report: 36048c7b-132c-4222-aae7-6e2acb6c8c6e. These baseline failures are not a green result for this PR.

Research methods and limitations: docs/benchmarks/source-family-census.md, with current primary MalPR-Bench and SWE-Review references. Exact private source/control evidence remains under ~/.devkit/research/sc2002-families. No model benchmark calls were made.

Ship: all blocking deterministic and reviewer gates passed, with no reviewer waiver. Advisory findings remain for validator/census complexity and dependency-cycle detection (the census names CLI/worker paths for source-closure hashing; it does not import/execute them). The two skill-projection orphan warnings refer to unrelated i-have-adhd files outside this PR. GitHub CI is pending on head 73947eb.

  • New Features

    • Added support for measuring source visibility and coverage across benchmark review tasks.
    • Added validation and reporting for isolated benchmark census runs.
  • Tests

    • Expanded coverage for manifest validation, source visibility, planner behavior, isolation, and error handling.

A broader wrapper typecheck traverses pre-existing untyped decisions benchmark modules and reports legacy errors, with no diagnostics in these new modules. Full local suite is running and its result will be recorded separately; it has already reported failures in unchanged receipt-resume and review-event integration tests.

Review Change Stack

📝 Walkthrough

Walkthrough

This change adds a zero-judge source census. It defines manifest validation, measures source-span visibility in native evidence, runs isolated pinned-tree census jobs, adds extensive tests, and records the census results and documentation.

Changes

Source census

Layer / File(s) Summary
Manifest contract
gate-engine/review/eval/reviewers/scale/corpus/manifest.mts, gate-engine/review/eval/reviewers/scale/corpus/__tests__/manifest.test.mts
Defines strict census schemas, validates family and bug/repair relationships, and hashes canonical manifests.
Visibility and planning
gate-engine/review/eval/reviewers/corpus/chunk-guard.mts, gate-engine/review/eval/reviewers/scale/corpus/visibility.mts, gate-engine/review/eval/reviewers/scale/corpus/__tests__/{visibility,shapes}.test.mts, gate-engine/review/eval/reviewers/scale/corpus/tsconfig.json
Adds caller-provided diff planning and classifies required spans as supplied, partial, omitted, truncated, out-of-scope, or not-in-diff.
Census execution
gate-engine/review/eval/reviewers/scale/corpus/{census,census-cli,census-worker}.mts, gate-engine/review/eval/reviewers/scale/corpus/__tests__/census.test.mts
Validates private inputs, reconstructs pinned Git sources, verifies tasks and evidence, records hashes and coverage, and isolates CLI output and errors.
Benchmark records and documentation
docs/benchmarks/{README.md,source-family-census.md,source-family-census.json}, README.md
Adds the source-family census report and findings, and updates dashboard freshness and current-suite text.
