Intent as Categorical Morphism

From Geb: intents are morphisms in a bicartesian closed category.

;; Intent structure in Geb
(define intent-type
  (prod
    (prod address address)         ; (owner, solver)
    (prod resource-type            ; nullify (give)
          resource-type)))         ; commit (receive)

;; Obstruction pass intent
(define (obstruction-pass-intent owner obs target-chain)
  (make-intent
    :owner owner
    :nullify (obstruction-resource obs)
    :commit (receipt-resource target-chain obs)
    :constraint (vcg-payment-constraint (h1-class obs))))

Cross-Chain Obstruction Flow

Step 1: Create Intent on Aptos

// From obstruction_hot_potato.move
public entry fun create_pass_intent(
    player: &signer,
    obstruction_idx: u64,
    target_chain: vector<u8>,
    max_vcg_payment: u64,
) acquires Player {
    let player_data = borrow_global_mut<Player>(signer::address_of(player));
    let obs = vector::borrow(&player_data.obstructions, obstruction_idx);

    // Create intent: nullify obstruction, receive receipt
    let intent = Intent {
        owner: signer::address_of(player),
        nullify: obs,
        commit: CrossChainReceipt { chain: target_chain, obs_hash: hash(obs) },
        vcg_constraint: compute_externality(obs.h1_class),
    };

    emit_intent(intent);
}

Step 2: Solver Matches on Anoma

class AnomaObstructionSolver:
    """Match cross-chain obstruction pass intents."""

    def match_intents(self,
                      aptos_nullify: Intent,
                      target_commit: Intent) -> Optional[Transaction]:
        # Verify complementary structure
        if not self.complementary(aptos_nullify, target_commit):
            return None

        # Compute VCG payment
        h1_class = aptos_nullify.obstruction.h1_class
        vcg_payment = vcg_externality(h1_class)

        # Extract solver fee
        solver_fee = vcg_payment * self.extraction_rate

        # Build matched transaction
        return Transaction(
            nullifications=[aptos_nullify.nullify],
            commitments=[target_commit.commit],
            payments=[
                Payment(aptos_nullify.owner, vcg_payment),
                Payment(self.address, solver_fee)
            ],
            gf3_sum=aptos_nullify.trit + target_commit.trit + (-1)  # Must be 0 mod 3
        )

    def verify_gf3(self, tx: Transaction) -> bool:
        return tx.gf3_sum % 3 == 0

Step 3: Execute on Target Chain

-- Commit obstruction on target chain
commitObstruction : Obstruction -> ChainState -> ChainState
commitObstruction obs state :=
  let newState := addObstruction state obs
  in if gf3Conserved newState
     then newState
     else abort "GF(3) violation";

-- GF(3) check
gf3Conserved : ChainState -> Bool
gf3Conserved state :=
  let sum := foldr (+) 0 (map trit (obstructions state))
  in sum `mod` 3 == 0;

Juvix Intent DSL

-- Intent type
type Intent := mkIntent {
  owner : Address;
  nullify : Resource;
  commit : Resource;
  constraints : List Constraint
};

-- Obstruction as resource
type Obstruction := mkObstruction {
  sexp : ByteArray;
  trit : GF3;
  h1Class : Nat;
  color : Word64
};

-- Cross-chain pass intent
passObstructionIntent : Address -> Obstruction -> ChainId -> Intent
passObstructionIntent owner obs targetChain :=
  mkIntent {
    owner := owner;
    nullify := obstructionResource obs;
    commit := receiptResource targetChain obs;
    constraints := [vcgConstraint (h1Class obs)]
  };

-- Compile to Geb morphism
compileIntent : Intent -> Geb.Morphism
compileIntent intent :=
  Geb.pair
    (Geb.injectLeft (nullify intent) Geb.so0)
    (Geb.injectRight Geb.so0 (commit intent));

Spectral Gap Preservation

Cross-chain obstruction passing must preserve spectral gap:

function cross_chain_spectral_check(
    source_game::OpenGame,
    target_game::OpenGame,
    obstruction::Obstruction
)
    # Source chain spectral gap
    gap_source = spectral_gap(strategy_graph(source_game))

    # Obstruction penalty to spectral gap
    penalty = obstruction.h1_class * PENALTY_COEFFICIENT

    # Target chain must absorb without breaking Ramanujan
    gap_target = spectral_gap(strategy_graph(target_game))
    gap_after = gap_target - penalty

    ramanujan_bound = 3 - 2√2  # For d=3 (GF(3))

    if gap_after < ramanujan_bound
        return :expansion_failure
    else
        return :ok
    end
end
