…nario A The Buildathon demo app referenced MockPendleRouter (envelope-builder.ts imports getMockPendleRouterAddress, holds MOCK_PENDLE_ROUTER_ABI, points at contracts/src/MockPendleRouter.sol) but the contract and its deploy script did not exist - scenario A (Pendle yield swap) was undeployable. - contracts/src/MockPendleRouter.sol: deterministic 1:0.995 mock matching the ABI the app already expects. Token-agnostic (no real transfers), emits SwapExactTokenForPt, reverts InsufficientPtOut below minPtOut. Apache-2.0. - contracts/script/DeployMockPendleRouter.s.sol: Arbitrum Sepolia deploy script. - contracts/test/MockPendleRouter.t.sol: 5 tests incl. an end-to-end agent-signed envelope -> AgentPolicyGate -> router integration test. - DEPLOY.md: full copy-paste deploy runbook (both chains, allow-list step, signer-pair pre-check, deployed.json + decoder-data wiring, smoke test). - contracts/README.md: pointer to DEPLOY.md. Verification: forge test 20 passed (15 gate + 5 router), app tsc --noEmit clean. Contracts still need a funded-key deploy (Mike) - see DEPLOY.md.

Summary
Makes the Buildathon demo's scenario A (Pendle yield swap) actually deployable + runnable, and pre-writes the full deploy runbook so the on-chain deploy (which needs Mike's funded key) is copy-paste.
The gap: the app already referenced
MockPendleRouter(src/agent/envelope-builder.tsimportsgetMockPendleRouterAddress, holdsMOCK_PENDLE_ROUTER_ABI, and comments point atcontracts/src/MockPendleRouter.sol), but the contract and its deploy script did not exist. Scenario A could not be deployed end-to-end.Changes

Mock fidelity
The mock's fixed 995/1000 rate is exactly what
buildPendleEnvelopeassumes: it setsminPtOut = amountIn * (10000 - slippageBps) / 10000, so any declared slippage of 50 bps or looser succeeds and anything tighter revertsInsufficientPtOut- the same shape a real router would present. The integration test pins the 50 bps boundary.What this does NOT do
forge scriptrun (Mike) - the whole point ofDEPLOY.md.buildRwaEnvelopestill throws "not implemented" (Phase 2 Day 10).DEPLOY.mddeploys the Robinhood gate only, for the multi-chain claim.Notes for review
MockPendleRouteris intentionally stateless and token-free. If you want the demo to show a real ERC-20 pull (approve + transferFrom), that is a larger change and would need a mock input token + an approve leg in the envelope.DEPLOY.mdflags the two silent-failure traps explicitly: skipping the allow-list, and a signer-pair mismatch. Both compile + deploy fine and only revert at execute time.Leaving this open for your review - not merging.
