Paper Claim Audit

Paper Claim Audit: Zero-Context Evidence Verification

Verify that every claim in the paper matches raw evidence for: $ARGUMENTS

Why This Exists

The executor writes experiments AND writes the paper. It "knows" what the results should be. This creates confirmation bias:

• Rounding 84.7% up to 85.3%
• Reporting best seed instead of average
• Citing metrics from a different experiment config
• Claiming "improves by 15%" when the delta is actually 12.8%

A fresh reviewer with zero prior context catches these because it has no expectations — it just compares paper text vs raw files.

How This Differs From Other Audit Skills

Core Principle

Zero-context, fresh reviewer. The auditor receives ONLY:

• Paper .tex files (the claims)
• Raw result files (the evidence)

It does NOT receive:

• ❌ EXPERIMENT_LOG.md
• ❌ EXPERIMENT_TRACKER.md
• ❌ AUTO_REVIEW.md
• ❌ NARRATIVE_REPORT.md
• ❌ Any executor summary or interpretation
• ❌ Any prior audit results
• ❌ Any conversation history

This is stricter than reviewer-independence — it's zero-context evidence audit.

Workflow

Step 1: Collect Files (Executor — Claude)

Locate paper and result files WITHOUT reading or interpreting them.

Paper files (claims) — paths shown relative to the shell's working directory so you can find them with ls; when writing them into audited_input_hashes, use paths relative to the paper dir (no paper/ prefix) per the "Submission Artifact Emission" section below:

paper/main.tex                # → hash key: main.tex
paper/sections/*.tex          # → hash key: sections/*.tex
paper/tables/*.tex (if separate)   # → hash key: tables/*.tex

Result files (evidence):

results/*.json, results/*.jsonl, results/*.csv, results/*.tsv
outputs/*.json, outputs/*.csv
wandb-summary.json (if exists)
**/metrics.json, **/eval_results.json
**/config.yaml, **/args.json (experiment configs)

Exclude (no summaries, no interpretations):

EXPERIMENT_LOG.md, EXPERIMENT_TRACKER.md, AUTO_REVIEW*.md
NARRATIVE_REPORT.md, PAPER_PLAN.md, findings.md
Any .md file that is an executor-written summary

Step 2: Fresh Reviewer Audit (GPT-5.4 — NEW thread, no reply)

CRITICAL: Use mcp__codex__codex (new thread), NEVER mcp__codex__codex-reply. Every run must be a fresh context.

mcp__codex__codex:
  model: gpt-5.4
  config: {"model_reasoning_effort": "xhigh"}
  prompt: |
    You are a paper-to-evidence auditor. You have ZERO prior context about
    this research. You will receive only paper source files and raw result
    files. Your job is to verify that every number in the paper exactly
    matches the raw evidence.

    Paper files to read:
    [list .tex file paths]

    Result files to read:
    [list .json/.csv/.yaml file paths]

    ## Audit Protocol

    ### A. Extract Every Quantitative Claim
    For each number, percentage, comparison, or scope statement in the paper:
    - Location (section, table, caption, or inline text)
    - Exact claim text
    - The number or comparison being made

    ### B. Trace Each Claim to Evidence
    For each extracted claim, find the supporting raw data:
    - Which result file contains this number?
    - What is the EXACT value in that file?
    - Match status: exact_match / rounding_ok / mismatch

    ### C. Check These Specific Failure Modes

    1. **Number inflation**: Paper says 85.3%, raw file says 84.7%
       Rule: only standard rounding to displayed precision is allowed

    2. **Best-seed cherry-pick**: Paper says "achieves 90.2%" but
       that's the best of 5 seeds; mean is 87.1%
       Rule: check if paper specifies "average" / "best" / "median"

    3. **Config mismatch**: Paper compares Method A vs Baseline B,
       but they used different hyperparameters / datasets / splits
       Rule: verify config files show same settings for compared methods

    4. **Aggregation mismatch**: Paper says "average over 5 seeds"
       but result files show only 3 runs
       Rule: count actual runs vs claimed count

    5. **Delta error**: Paper says "improves by 15%" but
       actual delta is (85.3 - 73.1) / 73.1 = 16.7%
       Rule: verify arithmetic of all relative improvements

    6. **Caption-table mismatch**: Figure caption describes
       something different from what the figure/table actually shows
       Rule: cross-check every caption against its content

    7. **Scope overclaim**: Paper says "consistently outperforms"
       but only tested on 2 datasets
       Rule: check if language matches actual evaluation scope

    ## Output Format (per claim)
    For each claim, report:
    - claim_id: sequential number
    - location: section/table/figure
    - paper_text: exact quote from paper
    - paper_value: the number claimed
    - evidence_file: which raw file
    - evidence_value: the actual number
    - status: exact_match | rounding_ok | ambiguous_mapping |
              missing_evidence | config_mismatch | aggregation_mismatch |
              number_mismatch | scope_overclaim | unsupported_claim
    - details: explanation if not exact_match

    Overall verdict: PASS | WARN | FAIL

Step 3: Write Report (Executor — Claude)

Parse the reviewer's response and write PAPER_CLAIM_AUDIT.md:

# Paper Claim Audit Report

**Date**: [today]
**Auditor**: GPT-5.4 xhigh (fresh zero-context thread)
**Paper**: [paper title from tex]

## Overall Verdict: [PASS | WARN | FAIL]

## Claims Verified: [N total]
- exact_match: [count]
- rounding_ok: [count]
- ambiguous_mapping: [count]
- missing_evidence: [count]
- mismatch: [count]

## Issues Found

### [FAIL/WARN] Claim #N: [description]
- **Location**: Section X / Table Y / Figure Z
- **Paper says**: "..."
- **Evidence shows**: ...
- **Status**: [status]
- **Fix**: [specific correction needed]

## All Claims (detailed)

| # | Location | Paper Value | Evidence Value | Status |
|---|----------|-------------|---------------|--------|
| 1 | Table 2 | 85.3% | 85.28% | rounding_ok |
| 2 | Abstract | "15% improvement" | 12.8% | number_mismatch |
| ... |

Also write PAPER_CLAIM_AUDIT.json for machine consumption.

Step 4: Print Summary

When to Run

1. After /paper-write — first check before improvement loop
2. After /auto-paper-improvement-loop — recheck if improvement loop changed numbers
3. Before submission — final verification

Integration with Other Skills

Read by /auto-paper-improvement-loop (if exists)

if PAPER_CLAIM_AUDIT.json exists:
    read mismatched claims
    fix them as priority items in the improvement round

Advisory, Never Blocking

Same pattern as /experiment-audit:

• PASS → continue normally
• WARN → print warning, continue, flag draft as "check numbers before submission"
• FAIL → print alert, continue, but do NOT mark as submission-ready

Key Rules

• Fresh thread EVERY run. Never use codex-reply. Never carry context.
• Zero executor interpretation. Only file paths. No summaries.
• Only raw results. No EXPERIMENT_LOG, no AUTO_REVIEW, no human summaries.
• Rounding rule. Only standard rounding to displayed precision. 84.7% → 84.7% or 85% is OK. 84.7% → 85.3% is NOT OK.
• Cross-model. Reviewer must be a different model family from executor.

Review Tracing

After each mcp__codex__codex or mcp__codex__codex-reply reviewer call, save the trace following shared-references/review-tracing.md. Use tools/save_trace.sh or write files directly to .aris/traces/<skill>/<date>_run<NN>/. Respect the --- trace: parameter (default: full).

Submission Artifact Emission

This skill always writes paper/PAPER_CLAIM_AUDIT.json, regardless of caller or detector outcome. A detector-negative run (paper has no numeric claims) emits verdict NOT_APPLICABLE; a paper-with-numeric-claims-but-no- raw-results run emits BLOCKED. Silent skip is forbidden — paper-writing Phase 6 and tools/verify_paper_audits.sh both rely on this artifact existing at a predictable path.

The artifact conforms to the schema in shared-references/assurance-contract.md:

{
  "audit_skill":      "paper-claim-audit",
  "verdict":          "PASS | WARN | FAIL | NOT_APPLICABLE | BLOCKED | ERROR",
  "reason_code":      "all_numbers_match | rounding_drift | missing_raw_results | ...",
  "summary":          "One-line human-readable verdict summary.",
  "audited_input_hashes": {
    "main.tex":                              "sha256:...",
    "sections/5.evidence.tex":               "sha256:...",
    "/abs/path/to/results/run_2026_04_19.json": "sha256:..."
  },
  "trace_path":       ".aris/traces/paper-claim-audit/<date>_run<NN>/",
  "thread_id":        "<codex mcp thread id>",
  "reviewer_model":   "gpt-5.4",
  "reviewer_reasoning": "xhigh",
  "generated_at":     "<UTC ISO-8601>",
  "details": {
    "total_claims":   <int>,
    "mismatches":     [ ... per-claim issue records ... ],
    "result_files":   [ ... raw files consulted ... ]
  }
}

audited_input_hashes scope

Hash the declared input set passed into this audit invocation — i.e. the exact .tex files and raw result / config files this run read — not a repo-wide union and not the reviewer's self-reported subset. If a caller passed only main.tex + a single result file, hash those two files and no others. The external verifier rehashes these entries; any mismatch flags STALE.

Path convention (must match what tools/verify_paper_audits.sh expects): keys are paths relative to the paper directory (the arg passed to the verifier) for in-paper files — so main.tex, not paper/main.tex — and absolute paths for out-of-paper files such as external results/ dirs. The verifier resolves relative entries via os.path.join(paper_dir, key); prefixing with paper/ produces paper/paper/main.tex and false-fails as STALE.

Verdict decision table

Thread independence

Every invocation uses a fresh mcp__codex__codex thread. Never codex-reply. Do not accept prior audit outputs (PROOF_AUDIT, CITATION_AUDIT, EXPERIMENT_LOG, AUTO_REVIEW summaries) as input to this audit — the fresh thread preserves reviewer independence per shared-references/reviewer-independence.md.

Human-readable sibling

paper/PAPER_CLAIM_AUDIT.md is written alongside the JSON for readers. The JSON is authoritative for tools/verify_paper_audits.sh; the Markdown is for humans. The parent skill (paper-writing Phase 6) plus the verifier decide whether the verdict blocks finalization — this skill itself never blocks; it only emits.
