+## Summary
+- add repo guardrails (pre-commit, pytest marker config, WRDS detection helpers, CHANGELOG/AGENTS) and new Makefile/test logging hooks.
+- ship analytics/reporting tranche (IC/IR/deciles, FF5(+MOM) attribution, SPA tooling, WRDS config + docs + README updates) plus coverage tests.
+- enhance CI to lint, test (skipping wrds by default), check coverage, cache pip, build docs, and publish HTML coverage artifacts.
+
+## Testing
+- `pytest -vv --maxfail=1 --durations=25`
+- `pytest -m wrds -vv` *(skipped automatically: WRDS data root not configured on runner)*
+- `mkdocs build`
+
+## Artifacts
+- `artifacts/logs/pytest-20251110-205216.log`
