Remove all commented code and non-error logs

**Current Behavior**
Our console log is pretty noisy.

**Expected Behavior**
Only log error messages.
Remove any commented code.

Comments are fine, just not commented code.

Search the repository for console logging and commented-out code, then separate error messages from other logs and ordinary explanatory comments. Confirm that only error messages remain and that no commented code is left; the issue names no files or tests, so the full repository needs to be scoped first.
