Five Comments That Redesigned My LLM Verification Pipeline

Short summary

Commenters on an LLM verification experiment series identified a key architectural flaw: deterministic code checks should filter garbage outputs before any LLM call. The author reorganizes findings into a three-layer pipeline — code shape checks, code contract checks, then LLM for semantic residual only. This approach cuts wasted API budget and separates easy rejects from genuinely ambiguous cases.

• •Deterministic code checks catch garbage outputs at zero cost before LLM calls
• •Three-layer pipeline: shape check → contract match → LLM semantic residual
• •Layering doesn't fix the 75% false-negative wall but stops mixing easy rejects with hard cases
