+# Test Stability Ledger
+
+Tracks incident detection test stability across local and CI iteration runs. Updated automatically by `/cypress:test-iteration:iterate-incident-tests` and `/cypress:test-iteration:iterate-ci-flaky`.
+
+## How to Read
+
+- **Pass rate**: percentage across all recorded runs (local + CI combined)
+- **Trend**: direction over last 3 runs
+- **Last failure**: most recent failure reason and which run it occurred in
+- **Fixed by**: commit that resolved the issue (if applicable)
