Nothing to try yet
A new backoff check for denied artifact-list refreshes is recorded but never actually applied
What
When a request to refresh the list of artifacts is denied with a 401 or 403, Claude Code now records the denial (status, time, and token expiry). A new check exists that could use this record to hold off retrying for a period of time, but nothing in the current build actually calls that check.
Why
This is groundwork with no visible effect yet: the denial is logged and cleared on account switch, but retries after a denial aren't currently held back by it.
