Per plan Task 2.7:
- DELETE test_send_deprecated_emits_warning (obsolete after Phase 6; send()
is being removed)
- RENAME test_send_extracts_data_from_result -> test_send_result_does_not_emit_deprecation
(this is the regression test the plan said to KEEP; it now asserts the new
API does not emit a deprecation warning, instead of testing the old behavior)
- MIGRATE test_send_extracts_data_from_result (renamed to the above)
- MIGRATE test_send_returns_empty_string_on_error_result ->
test_send_result_returns_empty_data_with_error_on_auth_failure (asserts
the Result has data="" and not ok)
5 tests pass (down from 6; the deleted test removed 1; the renamed
test_send_extracts_data_from_result became test_send_result_does_not_emit_deprecation).
