# Automated accessibility evidence

`run.json` binds scope, Git revision/dirty state, deployment identifier, build
versions, tool/browser versions, engine limitations, results, and asset hashes.
`engines.json` records launch probes. Per-instance `<engine>/assets/<instance>.json`
files record route body SHA-256 hashes and are aggregated into `assets.json`.
`<engine>/<check>/<instance>.json` files hold check measurements;
`<engine>/aria/<instance>.yaml` holds accessible-tree snapshots.

These are automated checks only. They cannot establish conformance alone.
Agent-assisted inspection is a separate evidence level and cannot establish
conformance alone either. Qualified human review remains pending until a dated
report exists; independent external review is also pending.

F3 trial runs use a temporary evidence directory and do not commit generated
results. V1a and Close-out commit release-bound outputs here, with their actual
scope and limitations. A filtered or failed run must not be represented as a full
passing evaluation. Evaluation remains incomplete pending qualified review.
