What

list_to_2d_float_array now rejects negative sizes and length mismatches with an explicit ValueError instead of leaking numpy reshape noise. Empty 0×0 buffers remain valid.

Why

Depth helpers sometimes feed truncated flat buffers after empty image responses; clearer fail-closed errors help API callers.

Test plan

  • python3 PythonClient/airsim/tests/test_utils_reshape.py -v (4 tests)
  • Happy-path 2×2 reshape
  • length mismatch / negative dim paths

Does not touch string_to_* / write_file (see open #9795 / #9796).

Reject negative sizes and length mismatches with an explicit ValueError
instead of an opaque numpy reshape failure. Soft-empty 0x0 buffers stay
supported. Offline unit tests included (no simulator).
