v22_freeze_pause

Court-order freeze (frozen from submit for the order's duration, founder approval required, chain finalizes after the validator vote, gov can lift; module accounts never frozen). Founder veto on upgrade proposals with a sunset gov can only shorten; gov can rotate the founder emergency key. Pauses and halts lift themselves. EVM contract staking rewards no longer burned; block gas limit 150M. PRION cameras store a hash only. Rehearsed on a copy of the live state.
