How to Build the Diff

1. Read all result files from both audit dates
2. Parse YAML frontmatter from each
3. Create maps of item_id -> status for both audits
4. Compare:
   • Improvements: Items that were fail/partial in date1 but pass in date2
   • Regressions: Items that were pass in date1 but fail/partial in date2
   • New items: Items in date2 but not in date1
   • Still failing: Items that fail in both audits
   • No longer audited: Items in date1 but not in date2
5. Calculate overall pass rates for both audits

If Only One Audit Exists

Only one audit found for [project] ([date]).

Run another audit to enable comparison: /audit-start [project]

Auto-Select Dates

If no dates provided, use the two most recent audit dates:

/audit-diff backend-api
# Automatically compares the latest two audits

If only one date provided, compare it to the most recent other audit.
