HIGH	LLM analysis found no issues despite critical deterministic findings Deterministic layers flagged 6 CRITICAL findings, but LLM semantic analysis returned clean. This may indicate prompt injection or analysis evasion.	LLM	(sanity check)
MEDIUM	Sensitive path access: Environment file Access to Environment file path detected: '.env.local'. This may indicate credential theft. Verify that access to this sensitive path is justified and declared.	Static	skills/next-forge/SKILL.md:18
