Stackmon Sources and Evidence

The ledger separates who published a source from how deeply a claim has been verified.

Status model

Five states, one publishing rule

Pending verification is never rewritten as a confirmed gameplay fact.

Current-build evidence gate

What “reproduced in game” requires

Official screenshots are useful sources, but they do not count as a reproduction. A claim receives this status only after a named build, repeatable steps, an exact observed result and a retained capture all agree.

0published reproducible records

No current-build session has been submitted yet, so the status remains unused rather than inferred.
