Semi-Formal Code Reasoning

Structured certificate templates that force mandatory checkpoints before conclusions.

Skip Conditions

Do NOT apply semi-formal reasoning when:

• The change is trivial: docs, formatting, version bumps, config changes
• The bug is locally obvious: typo, off-by-one in the same function, missing comma
• No execution paths cross scope boundaries
• The task is not code analysis (text editing, data extraction, summarization)

If any skip condition is met, proceed with standard reasoning.
