Cert handoff

This skill owns lifecycle handoff behavior, not a copied vendor checklist. Current first-party/vendor requirements must come from the project's authorized, versioned sources.

Event contract

For every applicable event publish:

event id + source
precondition / active game state
state that must persist
input policy during interruption
resume/recovery state
failure/fallback path
evidence required by game-qa

Examples include suspend-resume, focus/overlay transitions, controller or primary input loss, storage/save failure and account/session changes.
