Benchmark Fp Fn Audit

React Doctor benchmark FP/FN audit

Perform an evidence-backed audit of React Doctor diagnostics across a benchmark corpus. Read the complete rule documentation, quantify the distribution of failures, inspect every relevant trial artifact, and independently perform a second pass for additional false positives and false negatives.

Corpus and required resources

For this benchmark, use:

/home/aidenybai/Developer/react-bench-internal/jobs/ReactBench-v1.1-beta-rd-0.9.3-consolidated-final-20260801

Read the complete React Doctor rule documentation from:

https://www.react.doctor/docs/rules

Read these repository review materials when they exist:

/home/aidenybai/Developer/react-bench-internal/docs/aiden-review

Do not treat prior reviews or reports as ground truth. Use them as leads and reverify every claim against the current benchmark revision.

For every inspected trial, locate and read:

• verifier/model.patch
• verifier/rd-before.json
• verifier/rd-after.json
• verifier/rd.log
• result.json
• reward and test logs, discovered with rg --files
• the task README, prompt, or review material
• the base and patched source files referenced by the patch

Inspect all trial directories, including primary and verified variants. Normalize duplicate task names and repeated patch hashes before computing task-level statistics.

Evidence rules

Classify findings conservatively:

• Confirmed FP: a diagnostic is caused by changed code, the behavior is intentional or required, and the rule contract does not apply or its recommended fix would regress behavior.
• Confirmed FN: a real defect exists in the base or final code, no applicable diagnostic is emitted, and an existing documented rule should cover it.
• Taxonomy gap: a real defect is present but no existing rule contract reasonably claims to cover it.
• Harness artifact: the result is caused by malformed output, stale baseline data, verifier behavior, generated files, or an untouched-file diagnostic.
• Candidate: plausible but missing enough evidence for confirmation.

Do not call a target-task miss a false negative. Do not call a diagnostic a false positive merely because the model failed tests. react_doctor=1 is a gate result, not proof that the code is correct.

Every confirmed finding must cite the exact trial, file, line or code span, rule documentation, diagnostic delta, task behavior, and test result. Separate strict rule misses from out-of-taxonomy gaps.

Workflow

1. Inventory the corpus

Use rg --files to enumerate trial artifacts. Record the benchmark revision, trial count, missing artifacts, duplicate variants, malformed reports, and available task reviews. Do not silently skip incomplete trials.

2. Build diagnostic distributions

Recompute distributions from raw rd.log, rd-before.json, and rd-after.json data. Rank by trial coverage before raw occurrence count. Report:

• total trials and artifact completeness;
• reward, test, and React Doctor gate tuple counts;
• direct NEW or introduced-diagnostic failures;
• health-mode NEW deltas;
• health-mode STILL target misses;
• baseline-to-head rule-count deltas;
• rule, category, severity, task, repository, and file concentration;
• changed-file versus untouched-file diagnostics;
• malformed or truncated reports;
• primary versus verified-task duplication;
• successful versus unsuccessful patch comparisons.

Always recompute before relying on a prior summary. Large files can inflate occurrence counts, so show both occurrence count and affected-trial count.

3. Inspect high-impact clusters

Prioritize high-coverage rules and exact introduced-diagnostic failures, especially:

exhaustive-deps
no-giant-component
js-set-map-lookups
no-array-index-as-key
js-combine-iterations
effect-needs-cleanup
no-adjust-state-on-prop-change
button-has-type
prefer-module-scope-static-value
no-static-element-interactions
prefer-module-scope-pure-function
no-pass-data-to-parent
no-pass-live-state-to-parent
no-derived-state
no-ref-current-in-render
click-events-have-key-events
rerender-lazy-ref-init
only-export-components
rerender-lazy-state-init

For each high-impact cluster, inspect representative positives, representative negatives, the largest task concentration, and sibling trials with different outcomes.

4. Perform the independent second pass

Search every trial for additional candidates, not just the known clusters. Apply these heuristics:

• Separate expensive lazy initialization from cheap empty Map, Set, and equivalent containers.
• Distinguish render-derived state from async status, media errors, retries, resource lifetimes, subscriptions, and transient UI state.
• For controlled components, distinguish required parent synchronization from effect loops or unnecessary data forwarding.
• Follow dangerous HTML values through local aliases, useMemo, wrappers, and helper functions; preserve provenance for trusted serializers such as KaTeX.
• Distinguish React-docs-blessed previous-prop comparisons from pure derived state and render-phase side effects.
• Inspect timers, promises, animations, abort signals, subscriptions, and stale closures for races that generic dependency or cleanup warnings do not directly explain.
• Check focus stealing, focus restoration, controlled selection, keyboard semantics, and ARIA transitions.
• Check thresholds, aliasing, destructuring, nested callbacks, JSX wrappers, computed properties, and TypeScript syntax.
• Verify that a diagnostic is on changed code and not a pre-existing issue, generated artifact, fixture, or untouched neighbor.
• For every proposed FP, find a nearby true-positive counterexample. For every proposed FN, find a nearby case the detector catches.

Known leads to independently recheck, without presuming their classification:

5. Produce audit artifacts

Write audit-only outputs under the benchmark directory:

audit/rd-0.9.3-second-pass.md
audit/rd-0.9.3-second-pass.jsonl
audit/rd-0.9.3-rule-distribution.tsv

Do not edit React Doctor source, benchmark source, task tests, or verifier data. The JSONL must contain one record per finding with:

{
  "id": "...",
  "classification": "confirmed_fp | confirmed_fn | taxonomy_gap | harness_artifact | candidate",
  "confidence": "high | medium | low",
  "rule": "...",
  "task": "...",
  "trial": "...",
  "file": "...",
  "lines": "...",
  "evidence": "...",
  "baselineDiagnostics": "...",
  "headDiagnostics": "...",
  "testStatus": "...",
  "rdStatus": "...",
  "rationale": "...",
  "recommendedAction": "..."
}

The Markdown report must contain: corpus/methodology, distributions, confirmed FPs, confirmed FNs, taxonomy gaps, harness artifacts, manual-adjudication candidates, prioritized rule fixes, and limitations.

Prioritize fixes using:

affected trial coverage × confidence × reproducibility

Never make a code change as part of this skill unless the user separately requests implementation of a confirmed rule fix.
