Research direction

Start with the ExecuteStatement path and the retryableThriftMethods entry mentioned in the report, then compare it with the SEA kernel handling. Review the expected-failure tests in the linked coverage PR and the reference driver PR. Done means a raw TCP connection close is retried for ExecuteStatement in both paths, rather than failing after one attempt.

Written by the indexing model from the issue text.

Description

Surfaced by the multi-language coverage fan-out while conformance-testing these SPEC-IDs against databricks/databricks-sql-nodejs.

Each is committed as an expected-failure (xfail) test in the coverage PR — the test asserts the CORRECT behavior and stays red until this driver is fixed.

ERRORRECOV-013: Thrift does not retry a transport-level failure (TCP connection close) on ExecuteStatement — surfaces the error after a single attempt (ExecuteStatement excluded from retryableThriftMethods)
ERRORRECOV-013: SEA kernel does not retry a raw connection-close on ExecuteStatement — fails after 1 attempt with 'HTTP request failed after 1 attempts' despite tagging the error retryable:true
