`review_call(context) -> CallPermit`

The core calls this read-only before every external call, from both margin_execute and public_liquidate. The validator picks its rules by the target program and returns a permit, or fails.

CallContext { mode, target_program, data, call_account_count, margin, authority, venue }
CallPermit  { margin_indexes, tokens_in, tokens_out, max_spent, opens_venue, data }

mode is Owner (from margin_execute) or Liquidation (from public_liquidate). In liquidation mode the validator may also rewrite the call’s data (data), for example to size a Phoenix withdrawal to what is available.

Rules by target

Target	File	Owner mode	Liquidation mode
Kamino Lend	`kamino.rs`	`deposit_reserve_liquidity`, `redeem_reserve_collateral`	Refused

Any other program, or any other instruction of these programs, is refused with UnknownProgram or CallNotAllowed. Details per integration: Swaps, Phoenix Perps, Yield Vaults.

Adding a protocol

Add its rules as a file in the validator (and, if its positions aren’t plain tokens, a reader in the oracle).
Upgrade that agent program.
admin_register_integration for the target program. Then admin_register_asset for any receipt token, or admin_register_venue for a venue.

The core is not changed or redeployed.
