## Summary
Follow-up fix for
[#46120](https://github.com/supabase/supabase/pull/46120).
PR #46120 correctly guarded against duplicate `POST /platform/cli/login`
calls using a `useRef`, but left `navigate` in the `useEffect` deps
array. Because the parent passes an inline lambda, `navigate` gets a new
reference on every render. This causes React to:
1. Run the effect cleanup mid-flight (setting `isActive = false`)
2. Re-run the effect, which hits the session-id ref guard and returns
early
When step 1 happens while the POST is in-flight, the response arrives
with `isActive === false`, silently drops the `navigate(...)` call, and
leaves status stuck at `{ _tag: 'loading' }` — the infinite spinner
reported in Slack.
## Fix
Store `navigate` in a ref (updated each render) and call
`navigateRef.current(...)` inside `createSession`. Remove `navigate`
from the deps array so parent re-renders never trigger a cleanup while
the POST is in-flight.
```ts
const navigateRef = useRef(navigate)
navigateRef.current = navigate // always up to date, never a dep
```
All 7 existing CLI login unit tests pass, including the "POSTs exactly
once even when parent re-renders" regression test.
## Test plan
- [ ] Run `pnpm test:studio tests/pages/cli-login.test.tsx` — all 7
tests pass
- [ ] Browser: `supabase login` flow completes and shows the
verification code screen without hanging on the loader
- [ ] DevTools Network: exactly one `POST /platform/cli/login` fires per
login attempt
