Theoretically it should be possible to correlate deployed code changes with the logs and traces preceding 500 errors; and then recreate the failure condition given a sufficient clone of production (in CI) to isolate and verify the fix before deploying new code.

Practically then, each PR generates logs, traces, and metrics when tested in a test deployment and then in production. FWIU that's the "personal" part of sprkl.
