Audit the six contracts in this repository that were written in-house and have never had an independent review, and only those: src/SwarmRelay.sol (including the new relayAndLiquidate and relayAndMark), src/Treasury.sol, src/Governed.sol, src/Parameters.sol, src/Registry.sol, src/ParameterizedVault.sol. Also audit the change to src/CDPVault.sol that replaced the deployment-based fee index with the checkpointed one (indexCheckpoint, indexCheckpointAt, pokeIndex, and stabilityFeeOf). Everything else in src/ was built and audited by the swarm across launches 458, 493, 517, 519 and 586 and is out of scope. Report findings only; change no code. Specific questions to answer, each with the reasoning that settles it: (1) Can anyone cause Parameters to apply a change whose values were never validated, or validated against state that no longer holds? (2) pokeIndex is permissionless and Parameters._apply calls it before writing a new rate — is there any ordering, reentrancy or self-call path in which a rate change reaches time that has already elapsed, or in which debtIndex decreases and underflows the subtraction in stabilityFeeOf? (3) bindVault is permissionless and gated only on the candidate vault's immutable parameters() matching address(this) — can that check be satisfied by a contract that is not the real vault, and what could such a binding do? (4) Is every authority a governor can reach bounded by the constants in Parameters, and is there any path from Parameters or Registry to the price feeds, the attester, the collateral token, or anyone's position? (5) Does the 48-hour delay actually guarantee a borrower can exit at the terms they borrowed under, for every one of the five parameters? (6) In SwarmRelay, can a caller make the relay submit an attestation that a feed would refuse if submitted directly, or make relayMany leave some feeds updated and others not in a way a reader could exploit? (7) ParameterizedVault creates its own Parameters when passed a zero address, and that Parameters binds its creator in its own constructor WITHOUT the verification bindVault performs - can anything other than the real vault end up bound this way, and can a vault end up sharing or borrowing another vault's Parameters? (8) relayAndLiquidate holds a liquidator's stablecoin and the seized collateral for the length of one call, pulls exactly debtToRepay rather than the allowance, forwards the seizure as a balance DELTA, and asserts both deltas are zero before returning - can any caller, token or vault make it end a call holding either token, pay the seizure to the wrong party, strand a caller's stablecoin, or let one caller's funds cover another's liquidation? (9) In Treasury, can sync be made to record a receipt that never arrived, or can withdraw send more than arrived?
