Problem: Object Matte had no After Effects comparison, and none can be made
on this Linux machine (no After Effects). The gap notes still listed the
viewer tool, background job and disk cache as missing.
Fix: docs/fidelity/object-matte.md states plainly that nothing is measured
yet and pins down the comparison for when an After Effects 26.2+ reference
is available: four original or openly licensed clips (the synthetic moving
disk from the engine tests, the disk with a jump, two objects with a box
prompt, one CC0/CC BY real clip), the prompt and settings, where reference
mattes stay (gitignored), and the metrics: per-frame IoU against After
Effects (headline), IoU against ground truth, boundary distance, soft-edge
error, temporal stability, drift and time per frame, plus a proposed pass
bar left to the maintainers. Linked from docs/fidelity/README.md.
docs/gaps.md (#14) and docs/target-app-parity.md now list what landed and
leave the comparison as the one remaining item.
