ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This fixes retry ordering in the Antigravity OAuth flow by awaiting failed-callback process cleanup and adds targeted coverage. Because it changes authentication and callback lifecycle handling, the sensitive-auth review requirement calls for human review. You can add or adjust custom eligibility rules. Learn more. |

What Changed
A failed callback delivery could let
complete()return before the Antigravity process closed, so an immediate retry could fail withAntigravity setup is already in progress.stopFlow()when callback delivery fails.sequenceDiagram participant Client participant Auth as AntigravityAuth participant Agent as Antigravity process Client->>Auth: complete(callbackUrl) Auth->>Agent: Forward callback Agent-->>Auth: Delivery fails Auth->>Auth: stopFlow() Auth->>Agent: Interrupt and close Agent-->>Auth: Process closed Auth->>Auth: operation = idle Auth-->>Client: Return setup error Client->>Auth: start() Auth-->>Client: Start new flowWhy
Before this change, the forwarding error handler forked
stopFlow(). That letcomplete()return while the Antigravity process was still closing. An immediate retry could observeoperation === "cancel"and fail withAntigravity setup is already in progress.Cleanup still belongs to the provider instance, so it survives a requester disconnect.
complete()now waits until cleanup closes the process and restores the idle state.This is a follow-up to #9348 and its sign-in retry review thread.

Note
Medium Risk
Changes auth flow lifecycle and fiber interruption timing on callback failure; incorrect cleanup ordering could still block retries or leave processes running.
Overview
Fixes a race where
complete()could return after callback forwarding failed while the Antigravity process was still shutting down, so an immediatestart()could hit "Antigravity setup is already in progress."stopFlowis now an uninterruptible Effect that still detaches the flow under the lock, then interrupts fibers and setsoperationback toidleonly after cleanup finishes. When forwarding fails, the error handler awaitsstopFlowin the same fiber (withinterruptForwarding: false) instead of forking cleanup to a sibling fiber, socomplete()does not resolve until process close and idle state are restored.Adds test harness hook
beforeProcessCloseand a regression test that blocks process shutdown to assertcomplete()stays pending until cleanup completes and a retry can start a new flow.Reviewed by Cursor Bugbot for commit 61b7d5c. Bugbot is set up for automated code reviews on this repo. Configure here.
Note
Fix
AntigravityAuthto finish failed callback cleanup before retrystopFlowdirectly in the forwarding effect's error path withinterruptForwarding: false, so cleanup and owned-process shutdown finish before the completion effect returns with the error.stopFlowis reworked as a named uninterruptible Effect; flow detachment and state publication happen under the lock, while child-fiber interruption happens after. The newinterruptForwardingoption (defaulttrue) lets callers avoid interrupting the forwarding fiber that is currently running cleanup; existing callers keep current behavior.process-closehook to the test harness to verify failed callback completion waits for cleanup and that a subsequent sign-in starts a new flow.stopFlownow runs cleanup without interrupting the forwarding fiber when called from the error path; callers relying on the forwarding fiber being interrupted during cleanup should passinterruptForwarding: trueexplicitly.Macroscope summarized 61b7d5c.
