- Around line 794-799: Update the managed Antigravity error handling around
fetch_with_managed_agy so readiness/startup failures fall through to the
offline-conversation path like AGY_NOT_FOUND_MESSAGE, while AuthRequired errors
and other actionable provider errors still propagate. Add a short-lived backoff
for recent non-auth readiness failures so repeated fetch_usage refreshes do not
relaunch agy during the cooldown.

- Around line 239-250: Update the expected path assertions in the test to
construct both values with PathBuf::join from the same roots supplied to
agy_binary_candidates, preserving the platform-specific executable name for the
local bin candidate.

🚀 Performance & Scalability | 🟠 Major | 🏗️ Heavy lift
The managed agy lifecycle runs blocking work on tokio worker threads. Port enumeration and process teardown are synchronous operations placed directly in async code, so each managed fetch can stall the shared runtime.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Build the expected paths with join so the test also passes on non-Windows hosts.
agy_binary_candidates builds these paths with join. On Linux join inserts /, and \ stays an ordinary character, so C:\Users\test\AppData\Local/agy/bin/agy.exe does not equal the single-component literal C:\Users\test\AppData\Local\agy\bin\agy.exe. Both assertions fail on a Linux runner.
Derive the expected values from the same roots the test passes in.

Summary
Make Antigravity quota refresh work when the desktop app is closed by launching a short-lived, task-owned
agysession in a hidden PTY.The provider still prefers an existing Antigravity language server or user-owned
agy. Only the fallback process is managed, its terminal output is drained without logging, readiness is bounded, and the exact owned child is stopped and reaped after the fetch. The current offline conversation-history snapshot remains available when neither Antigravity noragyis installed.This brings the Windows behavior in line with the upstream Antigravity fallback.
