The sum is a conversation.
Thousands of values collapse into one answer. Watch the GPU move from one-thread accumulation to workgroup and subgroup reduction.

Reduction initialization failed.
The compute reducer could not initialize.
The native lane follows the pinned official 262,144-element / 64-thread reduction shape; use the display selector to inspect input values, per-workgroup partials, or the final readback result.
