Module provision 

2026-09-26: The vision fixtures, written to ~/.metrale/artifacts/vision on load().

The images are compiled into the binary from crates/bench/assets/vision/ and written out only when a file’s bytes differ (write_asset_bytes), behind a content-derived Stamp, so a run that already provisioned writes nothing. The written directory lets an operator send the exact bytes a run used with any HTTP client.

The same files are in tests/fixtures/images/, and assets_match_the_repo_fixtures fails when the two copies differ. They are copied into the crate because cargo package does not include a path outside it. scripts/gen_test_images.py generates 01 to 09; it does not generate 10 to 16.

Owner: bench, vision. Invariants:

• provision commits the stamp only after every fixture write succeeded.

Constants

EXIF_PAIR

2026-09-26: The EXIF-orientation pair, kept out of the geometry ladder because the integrity leg checks what the model reports, not a token count.

FIXTURES

2026-09-26: The geometry ladder as (name, bytes, width, height): 01 to 08 square, landscape and portrait sizes up to 1280x720, 09 over the 1280 px fallback clamp, 10 and 11 geometry extremes, and 12 to 14 decode variants at 224x224.

PLUGIN_ID

2026-09-26: The artifact directory name: ~/.metrale/artifacts/vision.

Functions
