Sherlock Review

<default_to_action> When investigating code claims:

1. OBSERVE: Gather all evidence (code, tests, history, behavior)
2. DEDUCE: What does evidence actually show vs. what was claimed?
3. ELIMINATE: Rule out what cannot be true
4. CONCLUDE: Does evidence support the claim?
5. DOCUMENT: Findings with proof, not assumptions

The 3-Step Investigation:

# 1. OBSERVE: Gather evidence
git diff <commit>
npm test -- --coverage

# 2. DEDUCE: Compare claim vs reality
# Does code match description?
# Do tests prove the fix/feature?
