In `@src/main/utils/connectors.ts`:
- Around line 187-194: In `connectors.ts` and `snowflake.extractor.ts`, add an
`openExternalBrowserCallback` to the query and extraction OAuth connection
configurations that throws an error containing `SNOWFLAKE_REAUTH_MESSAGE`,
preventing the SDK from opening a browser when cached credentials are unusable.
Import the message from `snowflakeAuth` where needed; keep `hasSnowflakeToken()`
as the pre-check and leave the dedicated Connections-screen browser callback
unchanged. `snowflakeAuth.ts` is cited as evidence of the separate screen flow
and requires no direct change.
In `@src/main/utils/snowflakeAuth.ts`:
- Around line 288-325: Update readCachedOAuthAccessToken to silently connect
through the Snowflake SDK for the named connection’s account and user before
reading the cache, using an openExternalBrowserCallback that throws to prevent
browser launch. Return only the cached token whose key hash matches that
connection’s identity, and return null if the silent connection fails.
In `@src/renderer/components/connections/snowflake.tsx`:
- Around line 346-375: In the Snowflake connection test handler, guard result
and error handling with a check that activeCorrelationIdRef.current still
matches this attempt’s correlationId, so stale attempts cannot update the toast
or connection state. In finally, clear the ref only when it still matches this
attempt.
In `@tests/unit/main/utils/snowflakeDbTokenBridge.test.ts`:
- Around line 119-127: Update writeCacheFile to write the cache file at the
platform-specific path used by SnowflakeAuthManager.getSnowflakeCacheFile(),
rather than always using Library/Caches/Snowflake; ensure the manager resolves
that path inside the test’s temporary home directory.

Normalize saved Snowflake identity fields before OAuth reuse.
The save path stores formState without trimming. The silent path passes those values unchanged, while browser authentication uses trimmed values. If the saved connection contains surrounding whitespace, the SDK can compute a different OAuth cache key and miss the cached session. Trim both fields before the silent connection and use the normalized username in the hash.
