The Node runner calls the reference dispatchAction for all 192 local fixtures. A separate project-authored Python oracle checks each row, including receipt, digest, claim consumption, callback target, and marker write. CI rejects four deliberately falsified reports.
Reproduce with node pilots/action-boundary/dispatch-matrix.mjs --check and python3 pilots/action-boundary/verify_dispatch_matrix.py docs/action-dispatch-matrix.json. Read the method and limits ↗
Scope: Finite project-authored callbacks, no human approval, provider call, arbitrary interleavings, real delivery, outside witness, or formal proof of production safety. A browser view of the report does not independently verify its provenance. Never silently retry an unknown result.
