Caster School
Caster School is the standalone Caster OS route for signed Farcaster quizzes, Snap question flow, follow and /casterschool channel gates, proof-cast verification, and $CASTER rewards after strict runtime receipts pass. This fallback is live for navigation and verification while signed FID progress, proof verification, claim writes, reward ledger writes, wallet settlement, rate-limit mutation, anti-replay writes, QStorage, event-log, rollback, and production datastore mutation stay blocked_external.
Read-only fallback for the Caster School Snap catalog, daily quiz route, and Farcaster mini app shell.
Signed FID, @casterchain follow, /casterschool channel, and proof-cast verification stay blocked until runtime receipts pass.
$CASTER quiz claim store, reward ledger writes, and Caster Wallet settlement are blocked until strict evidence passes.
Rate limits, anti-replay state, QStorage, Caster event-log append, and rollback lanes require strict runtime evidence.
