- #140568: \[Bug\]: Same-provider fallbacks always skipped — _candidate_pool_exhausted treats next_available_at()=None as exhausted (Vertex SA credentials)
- PR #140615: fix(agent): treat a pool with no wait information as unexhausted for fallback

The members describe one theme: a candidate pool whose next_available_at() returns None is treated as exhausted, which causes same-provider fallbacks to be skipped (reported with Vertex SA credentials). Two pull requests propose changing this handling and one bug report describes the behavior; their outcomes are not stated in the titles.

## TL;DR
