From 7f1d52eb35e7aeeb1024977bbb14a9487da14fbc Mon Sep 17 00:00:00 2001 From: fullsend-code <278716306+fullsend-ai-coder[bot]@users.noreply.github.com> Date: Thu, 13 Aug 2026 16:19:02 +0000 Subject: [PATCH 1/6] fix(#52): add post-generation validation and LLM verification Add two-layer validation after content generation to prevent the LLM from removing or rewriting existing documentation that is unrelated to the code diff: 1. Diff-based preservation check: uses difflib.SequenceMatcher to compare original vs generated content and flags updates that remove more than 20% of original non-blank lines. 2. Independent LLM verification: a separate LLM call (fresh session, not biased by the generation context) reviews the update against the original and the code diff, checking that only diff-related content was changed and reviewer instructions were followed. When either check fails, the system regenerates with explicit preservation constraints. If the regenerated output still fails the preservation check, the update is skipped (NO_UPDATE_NEEDED) to protect existing documentation. New public functions: validate_content_preservation(), verify_update_with_llm(). Both are called automatically from ask_ai_for_updated_content() after format validation passes.

Preservation check adds a 30-line minimum-size guard and partial credit for reworded lines. P1: ask_ai_for_updated_content returns GenerationResult with verification_status so outcomes are visible in PR comments. Document content in the verification prompt is delimited and budget-capped. The verifier receives the same truncated diff the generator saw. Regeneration comment matches actual behavior.
