Module concurrency 

2026-09-26: The concurrency leg shared by the video and vision benchmarks: for each of LEVELS, that many copies of one request are sent at once and scored for how many returned, how many were correct, and whether they agree on one prompt-token count.

It checks correctness, not throughput: wall_ms is recorded and never read by ok, ok_against or sweep_ok. The copies are identical, so this leg cannot see one request answered with another’s input; media_integrity::heterogeneous_concurrency covers that.

Owner: bench, video and vision. Invariants: none beyond the types.

Structs

LevelResult

2026-09-26: One level’s outcome.

Constants

LEVELS

2026-09-26: The levels swept, in order. sweep_ok needs one result per level, and the first (C=1) sets the prompt-token baseline.

Functions

run_level

2026-09-26: Send conc copies of body at once and score them with is_correct.

sweep_ok

2026-09-26: True when there is one result per LEVELS entry, in order, and each is ok_against the first result’s prompt-token count.
