Backlog consolidation against dev ada3a9bFollowing the repository owner's request to consolidate superseded proposals, keep this PR as the active proposal for Antigravity model-family quota ranking and cooldown isolation; close the overlapping alternative #4299 as superseded, not as implemented or released. I compared the complete current diffs: #4299 at 2a1b32a and this PR at 8156244. Both implement requested-model headroom/exhaustion ranking and thread the model through initial selection plus the five split Responses rotation owners. This PR additionally scopes cooldown health by family and handles fill-first/round-robin selection. #4299 still has the cross-family cooldown review finding. Preserve these differences as explicit remaining review work here, rather than silently dropping them with the alternate PR:
Existing sponsorship/security review, draft/readiness requirements and maintainer objections remain in force. No approval, merge, CI pass, release, or source modification is implied by this consolidation. #3375 remains open for the rest of the OAuth-pool lifecycle. |

fetchWithTransientRetrycan return the markedREPLAY_REFUSED_STATUS429 response when the request may already have reached the origin. The generic OAuth branch then callsrebuildAndRefetch, which rebuilds an equivalent request and sends its body under the next OAuth account. The same-target loop reuses the current method, headers, and body. The send budget only limits attempts; it does not make the operation idempotent or prevent a duplicate upstream call.Restore the guard in both 429 conditions and restore the import:

Summary
Make generic OAuth ranking and 429 cooldown model-family aware for
google-antigravity.Gemini requests use
Gem/Gem (Weekly)windows only. Claude requests useCla/Cla (Weekly). A spent Claude window no longer ranks the account as exhausted for Gemini, and a Claude 429 cools only the Claude family so the same account can still serve Gemini.Unknown labels and Gemma ids fall back to the current unranked ring. Codex and Anthropic paths are unchanged.
Refs #3375. Complements the GUI pool-settings panel; does not add a dedicated Antigravity router.
