auth token expired mid-run while pulling Chorus call batch for competitor mention extraction

Pause the batch, reconnect the Chorus connection through its normal sign in flow, resume from the first call that failed rather than the start, and add a check that stops the run cleanly on an access failure instead of retrying every remaining call. Use when you see this exact failure: auth token expired mid-run while…

Opaque API token non expiring nullable expiration explicit opt in revocation validation legacy token migration

Shows how to support non-expiring opaque API tokens safely: model expiration as an explicit policy instead of a bare nullable timestamp, require a recorded opt-in with a reason, fail closed on inconsistent rows, and migrate legacy tokens whose null expiration has unknown intent instead of silently making them immortal…

when agent tried to rename an experiment it failed because the tracking server returned a conflict error

Rename by creating the new experiment and moving runs when the server will not rename in place: a conflict response means the target name is taken, possibly by a deleted experiment holding the name, or the API does not support renames and the create step collided. Use when an agent renaming an MLflow or tracker experi…
