# Which issue does this PR close? - Closes #11588. # Rationale for this change `MutableArrayData::extend` on a `FixedSizeList` with a nonzero parent offset copied the child values from the start of the child instead of from the offset. # What changes are included in this PR? `build_extend` in `transform/fixed_size_list.rs` adds `array.offset()` to `start` before computing the child range, the same way #10934 did for structs. # Are these changes tested? Yes, `test_extend_fixed_size_list_accounts_for_parent_offset` in `arrow-data/src/data.rs` (next to the struct test from #10934). It fails without the fix. # Are there any significant user-facing changes? No. AI use: I used Claude Code to find the cause and write the fix and test. I reviewed the change and checked that the test fails without the fix. -- This is an automated message from the Apache Git Service.
