WalkthroughThe PR adds retention-mask APIs for C++ and Python, deprecates boolean-mask APIs with compatibility wrappers, and updates native, Python, Java, benchmark, and test call sites. ChangesRetention-mask API migration
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The new retention-mask API can accept size-mismatched empty masks or zero-row inputs instead of raising the promised error, creating a bounded correctness risk for callers.

- Around line 60-68: Update the deprecated apply_boolean_mask declarations in
cpp/include/cudf/lists/stream_compaction.hpp lines 60-68 and
cpp/include/cudf/stream_compaction.hpp lines 220-227 to explicitly document the
boolean_mask parameter, replacing or supplementing the copied
apply_retention_mask documentation so no retention_mask reference remains for
these signatures.
- Around line 45-52: Update the Doxygen comments for the affected public API:
remove the unmatched backtick after the `@p` input parameter reference, and
describe the return value as a std::unique_ptr<column> rather than a table while
preserving the existing list-column behavior.
In `@cpp/include/cudf/stream_compaction.hpp`:
- Around line 203-212: The apply_mask implementation must enforce exact
retention_mask size equality for all inputs, including empty masks and zero-row
input tables. Move the size validation ahead of the empty-mask early return in
detail::apply_mask, preserving the existing filtering behavior only after sizes
match.

Correct the public API documentation.
Line 46 has an unmatched backtick after @p input. Line 51 refers to a returned table, but this API returns std::unique_ptr<column>. Correct both descriptions.
As per coding guidelines, public functions in cpp/include/cudf/ require Doxygen documentation.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Make the size-validation contract match the implementation.
Line 203 states that every size mismatch raises cudf::logic_error. However, detail::apply_mask in cpp/src/stream_compaction/apply_boolean_mask.cu returns before validation when the mask is empty, and it accepts any mask size when input.num_rows() is zero. A one-row table with an empty mask therefore returns an empty table instead of raising.
Validate exact size equality before the empty-mask shortcut, or document these compatibility exceptions.
