+# CI Flake Analysis - 2026-02-27
+
+## Summary
+The full test suite was run 4 times (1 initial run + 3 loop runs) to detect flaky tests.
+
+**Command:** `PYTHONPATH=src python3 -m pytest`
+
+**Results:**
+- **Initial Run:** 766 passed, 11 skipped
+- **Loop Run 1:** 766 passed, 11 skipped
+- **Loop Run 2:** 766 passed, 11 skipped
+- **Loop Run 3:** 766 passed, 11 skipped
+
+## Conclusion
+No flaky tests were detected in the current environment. The test suite appears stable.
+
+## Skipped Tests
+The following tests were skipped in all runs (likely due to missing optional dependencies or configuration):
+- `src/tests/test_concurrency_stress.py` (3 skipped)
+- `src/tests/test_gui_features.py` (3 skipped)
+- `src/tests/test_nostr_index_size.py` (1 skipped)
+- `src/tests/test_nostr_real.py` (3 skipped)
+- `src/tests/test_nostr_sdk_workflow.py` (some possibly skipped or passed, log shows passed)
+
+*Note: The number of skipped tests (11) remained consistent across all runs.*
