-## Key findings
-- The `scheduler-flow.md` script execution failed due to a missing runner (`codex`).
-- The automated `bug-reproducer-agent` prompt execution failed.
-- Fallback manual investigation identified one active issue: `BIP85 Non-Standard Derivation Path` (using `app_no=2` instead of standard). This is documented in `KNOWN_ISSUES.md`.
-
-## Patterns / reusable knowledge
-- Future runs should verify the runner environment variables (`SCHEDULER_PROMPT_PATH`, `SCHEDULER_AGENT`, `SCHEDULER_CADENCE`) are set correctly before invoking `run-selected-prompt.mjs`.
-- If the runner fails, manual fallback or alternative automation (e.g., Python script) is required.
-
-## Warnings / gotchas
-- `torch/scripts/agent/run-selected-prompt.mjs` depends on an external runner (`codex` or similar) which may not be available in all environments.
+## Learnings
+* The default branch is `beta`. `git log` should target `beta` instead of `main` when reading history for this repository.
+* A `CHANGELOG.md` file exists and we append changes. Since no existing release notes dir was found, I created `releases/draft-YYYYMMDD.md`.
+* We use `poetry run black .` for formatting tests properly, but I reverted the changes to `torch/scripts` formatting since they were not meant to be changed by this agent.
