index.ts

// zhgg — unified TUI (raw ANSI; integrated payment flow + real-data wiring)
//
// Adds three live capabilities on top of the previous mock layout:
//   1. RECEIPT row — viem getTransactionReceipt + parseEventLogs decode
//      FeeSplitter.Split (Base Sepolia) and AgentRegistry.NewFeedback
//      (0G Galileo). NEVER fabricates fields. See `receipt-feed.ts`.
//   2. INTENT input — typed commands dispatch to runCrossAgentDemo
//      (audit) or queryOracle (ask oracle). Orchestrator events stream
//      into the AUDIT TRAIL and FLOW state.
//   3. SpendCap [G] grant — when an intent is staged, G pops a modal
//      that calls SpendCap.grantPermission() on Base Sepolia using
//      BASE_SEPOLIA_PRIVATE_KEY, scoped to the intent's permissionId.
//
// Requires: 120×40 terminal (warns if smaller). The new INTENT row +
// RECEIPT band push the minimum a few rows above the previous 28.

// ── Delegation dispatcher (Slice I — ERC-7710) ───────────────────────────────
//
// Issues a real redeemable delegation via the deployed `DelegationManager`
// on Base Sepolia (chainId 84532). The contract has a single redeemer
// entry point — `redeemDelegations(bytes[], bytes32[], bytes[])` — and
// the manager's "create" semantics are the act of (a) signing a
// `Delegation` struct off-chain via EIP-712 and (b) redeeming it on
// chain. We do BOTH atomically here so the operator types one line and
// gets a real on-chain receipt (or a verbatim revert).
//
// Resolution rules for `<to>`:
//   - 0x40-hex   → viem `getAddress` (any case accepted; checksummed).
//   - agent role name (`audit`, `oracle`, `swap`) → look up tokenId via
//     agent-registry, then read AgentNFT.ownerOf(tokenId) on 0G Galileo
//     (chainId 16602) using the bundle's `zgPub` client. Cross-chain:
//     read on 0G, write on Base.
//   - mainnet `*.eth` → reuse `resolveRecipient` from transfer-agent
//     (same free public RPC chain; honours `ENS_RPC_URL`).
//
// Hardcoded caveats (matching the on-chain Delegation struct field-for-field):
//   delegator        = bundle.receiverWallet (AgentReceiverWallet). The
//                      manager's ERC-1271 check calls isValidSignature on
//                      this contract; it validates the iNFT owner's EOA sig.
//                      Requires AGENT_RECEIVER_WALLET_ADDRESS in env.
//   delegate         = resolved <to>.
//   allowedTargets   = [SpendCap]    (only target the redemption may hit).
//   maxValuePerCall  = 0             (no native ETH).
//   expiresAt        = now + 1h      (DelegationExpired fires after).
//   salt             = random 32B    (parallel-safe replay defense).
//   spendCapAsset    = USDC          (debits the matching permissionId bucket).
//   permissionId     = intent.permissionId (verbatim).
//   maxAmountPerRedeem = 100_000     (0.1 USDC, 6dp).

// ── Slice X — `kh hire` close-the-loop dispatcher ───────────────────────────
//
// Closes the agentic-commerce loop: an iNFT in this TUI hires another
// agent's MCP-callable workflow on KeeperHub via x402. NO MOCKS — the
// path is:
//   1. `kh inspect <slugOrId>` — fetches `listedSlug`, `priceUsdcPerCall`,
//      `inputSchema` from `/api/mcp/workflows`. Refuses on `listedSlug ===
//      null` (workflow is discoverable but not yet slug-callable).
//   2. Validate required[] keys against operator-supplied JSON inputs;
//      refuse with the first missing key surfaced by name.
//   3. `payViaKeeperHubMarketplace` — the existing x402 round-trip.
//      Settles EIP-3009 USDC on Base Sepolia via KH's facilitator (30%
//      to KH, 70% to the workflow author). Returns the marketplace
//      tx hash + the workflow's response body.
//   4. Push three audit rows (intent, payment tx, truncated response)
//      and surface the FULL response JSON in the receipt panel.
//
// Honest refusal contract: if any required env var is missing we surface
// the EXACT names so the operator can fix .env and retry. We never
// fabricate a tx hash or synthesise a successful response — every byte
// comes off the wire.
