Abhay Singh's fix in PR 3239 stopped a single corrupt database row from aborting an entire graph scan, returning the good data instead of raising an error. That…
Second theme: correctness in the request path itself. PR 3258 fixes Claude requests failing with an invalid bearer token when routed through Copilot, because Copilot serves both its GPT and Claude surfaces from the same host but the provider registry wasn't accounting for that. PR 3246 fixes token refresh for…
