## Cause Async remote pandas conversion could call `AsyncTable.to_lance()`, which opened the server's table storage URI in the client process. This bypassed server query and authorization APIs. The first repair routed blob reads through the server, but a query and subsequent blob fetch could resolve different table snapshots after replacement or compaction. ## Fix - Reject `AsyncTable.to_lance()` for remote tables before requesting a table URI. - Convert remote nonblob and blob description results through the server Arrow path. - Reject automatic remote byte and lazy blob materialization until the server can bind the query and fetches to one verified table identity and version. The default lazy mode now raises `NotImplementedError` when a blob column is projected; callers can request `blob_mode="descriptions"`. ## Validation - Mocked remote tests cover direct storage rejection, description results, byte and lazy rejection before any blob fetch, and nonblob projections. - Focused local and remote blob tests passed (19 tests). `ruff check .`, `ruff format .`, and pyright passed.
