Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to The change centralizes Storage authentication and transport, but the current test suite still references non-existent StorageClient attributes and will raise AttributeError, so the PR is not merge-ready until those assertions are corrected. A beta warning is also suppressed when notice persistence fails and should be fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

This is a specific timeout for the Catalog describe operation. Normal storage requests have a separate 30s timeout

Summary
TOWER_JWTfirst, thenTOWER_API_KEY.http://Tower URLs usable for local development, and use bounded request timeouts.Why
This gives the Storage path one consistent authentication and request policy without changing the shared SDK client, the CLI, or CLI sessions. It is the private foundation for one-shot catalog loading and for a later managed
TableReferenceto retain only resolution/cache state—not network resources.The existing process-wide credential cache remains in this PR and is replaced by the next PR in the stack.
