A vesting contract shall never do

Rule	What it means, and the evidence the jury reads	Weight
EVC-01	MUST NOT release tokens before the cliff. Claims before the cliff timestamp return zero or revert. Evidence: claim logic, cliff constant	critical
EVC-02	MUST NOT release faster than the schedule. Released amount never exceeds the schedule at the current time. Evidence: vesting math, rounding	critical
EVC-03	MUST NOT let the issuer take back vested tokens. Revocation, if any, applies only to unvested tokens. Evidence: revoke function	critical
EVC-04	MUST NOT change the schedule, beneficiary or token without consent and a timelock. Changes need the beneficiary's signature and a delay. Evidence: admin and update functions	critical
EVC-05	MUST NOT let an admin withdraw unvested tokens outside the declared terms. Admin withdrawals follow the published revocation terms only. Evidence: withdraw and sweep functions	critical
EVC-06	MUST NOT lose tokens when a beneficiary changes. Transfers of a grant keep the full vested and unvested amounts. Evidence: beneficiary transfer logic	normal
EVC-07	MUST NOT sit behind an upgradeable proxy without a timelock. Upgrades, if possible, are timelocked and announced. Evidence: proxy and upgrade authority	normal
EVC-08	MUST NOT hide the schedule. Cliff, duration and amounts are readable on chain and match the published terms. Evidence: view functions, terms reference	normal

Critical rules weigh 3, others 1. PASS needs no fail and no needs-evidence, with at least 60% of the weight checkable from code.
