## Claim Specification

| Field | Value |
|-------|-------|
| Subject | LLM mathematical reasoning under GSM-NoOp-style adversarial conditions |
| SC1 | GSM-NoOp identifies pattern-matching limitations (threshold: ≥3 sources) |
| SC2 | Code-execution offloading practically surmounts these limitations (threshold: ≥3 sources) |
| Compound operator | AND |
| Operator note | Both sub-claims must hold. "Practically surmountable" = demonstrated methods exist that overcome the limitation in practice. SC2 relies on mechanistic evidence (no direct GSM-NoOp evaluation with code execution exists). |

## Independent Source Agreement (Rule 6)

### SC1: GSM-NoOp Findings

- 4 sources consulted, 4 verified (sc1_gsm_symbolic_paper: verified, sc1_emergentmind_summary: verified, sc1_appleinsider_report: verified, sc1_marcus_analysis: verified)
- Independence note: Original arxiv paper, EmergentMind analysis, AppleInsider tech press, and Gary Marcus Substack are editorially independent publications covering the same underlying research.
- All SC1 sources trace to the same primary research (Mirzadeh et al.), so this is "independently published (same upstream authority)" — the independence comes from editorial review, not independent measurement.
- COI flags: none

### SC2: Code Execution Surmounting Limitations

- 4 sources consulted, 4 verified (sc2_pal_paper: verified, sc2_code_reasoning_survey: verified, sc2_iipc_paper: verified, sc2_proof_engine_meta: verified)
- Independence note: PAL (ICML 2023), code-reasoning survey (2025), and IIPC (2025) are independent academic publications from different research groups. Proof engine is self-referential (COI flagged).
- COI flags: sc2_proof_engine_meta has institutional co-benefit COI (self-referential, favorable to subject, moderate severity).
- COI majority check: 1 COI-flagged source out of 4 verified — does not trigger majority override (1 < 4/2 = 2).

## Adversarial Checks (Rule 5)

**1. Direct GSM-NoOp evaluation gap**
- Question: Has any study directly tested code-execution approaches on GSM-NoOp?
- Verification: Searched 'PAL program-aided GSM-NoOp code execution distractor' and 'code execution GSM-NoOp benchmark results'
- Finding: No direct evaluation found in either direction. SC2 relies on mechanistic argument. Does not break proof — claim says "practically surmountable" not "empirically demonstrated on GSM-NoOp."
- Breaks proof: No

**2. Code-execution vulnerability to distractors**
- Question: Could code-execution still be vulnerable if LLM incorporates irrelevant info into generated code?
- Verification: Searched 'LLM code generation irrelevant information robustness' and 'program-aided reasoning distractor vulnerability'
- Finding: IIPC paper acknowledges "execution-guided agents can lack stabilizers against program bias." However, code requires explicit variable declaration, making irrelevant variables more likely to remain unused dead code. "Practically surmountable" ≠ "perfectly immune."
- Breaks proof: No

**3. Self-referential circularity**
- Question: Is the proof engine as meta-evidence circular?
- Verification: Structural analysis — proof engine is one of four SC2 sources, COI flagged, not required for threshold.
- Finding: Not circular. The proof engine is a concrete existence proof independent of its own claim. 3 other independent sources support SC2 without it.
- Breaks proof: No

**4. Reasoning models as alternative**
- Question: Do o1/o3 solve GSM-NoOp without code execution?
- Verification: Searched 'o1 o3 GSM-NoOp performance'. GSM-Symbolic paper notes o1-preview still shows "significant declines."
- Finding: Even o1-preview drops on GSM-NoOp. This strengthens SC1 and supports SC2.
- Breaks proof: No
