+
+## AGI/SAI Autonomy Gaps
+
+These are the 11 critical gaps identified that prevent fully autonomous AGI/SAI agents from using Baud without human intervention. Each gap is categorized by severity and phase.
+
+### GAP-1: No Sub-Accounts / Multi-Sig / Budgeting ⚠️ CRITICAL
+**Status**: Not started
+**Phase**: 2 (Agent Economy)
+**Problem**: An AGI agent cannot create sub-wallets, delegate spending to sub-agents, or set budgets for different tasks. A superintelligent system managing hundreds of sub-processes needs hierarchical financial control.
+**Solution**: Add `CreateSubAccount` tx type with parent/child relationships, budget limits, and delegated signing authority.
+
+### GAP-2: Spending Policy Co-Signer Validation BROKEN ⚠️ CRITICAL
+**Status**: ✅ DONE (CoSignedTransfer with multi-sig verification)
+**Phase**: 1 (Foundation Fix)
+**Problem**: `SetSpendingPolicy` transaction exists with `co_signers` and `required_co_signers` fields, but the enforcement code in `state.rs` only REJECTS over-limit transactions — it never validates co-signer approvals. There's no pending/approval queue.
+**Location**: `crates/baud-core/src/state.rs` → `validate_transaction()` function
+**Solution**: Implement pending transaction queue, co-signer signature collection, and threshold approval logic.
+
+### GAP-3: No Identity / Reputation System ⚠️ HIGH
+**Status**: ✅ DONE (RateAgent tx, Reputation struct, /v1/reputation endpoint)
+**Phase**: 2 (Agent Economy)
+**Problem**: Agents can't evaluate trustworthiness of other agents. No track record, ratings, or stake-based reputation. An AGI picking a service provider has zero data.
+**Solution**: Add on-chain reputation scores based on successful escrow completions, dispute outcomes, and stake amount. Add `RateAgent` tx type.
+
+### GAP-4: No Smart Contracts / Conditional Logic ⚠️ HIGH
+**Status**: Not started
+**Phase**: 3 (Programmability)
+**Problem**: Baud has exactly 8 hardcoded transaction types. No way to express "if X happens, pay Y" or any custom logic. AGI agents need programmable money.
+**Solution**: Either add a lightweight scripting engine (like Bitcoin Script) or a WASM-based smart contract runtime. Phase 3 feature — complex.
+
+### GAP-5: No Recurring Payments / Subscriptions ⚠️ MEDIUM
+**Status**: ✅ DONE (CreateRecurringPayment + CancelRecurringPayment tx types)
+**Phase**: 2 (Agent Economy)
+**Problem**: An agent that subscribes to a data feed, API service, or compute provider must manually send a payment every period. No auto-pay.
+**Solution**: Add `CreateSubscription` tx type: payer, recipient, amount, interval, max_periods. Node auto-executes payments at each interval.
+
+### GAP-6: No Agent-to-Agent Agreements / Contracts ⚠️ HIGH
+**Status**: ✅ DONE (ServiceAgreement lifecycle: Create → Accept → Complete/Dispute)
+**Phase**: 2 (Agent Economy)
+**Problem**: Two agents can't form a binding agreement (e.g., "I'll generate 1000 images for 10 BAUD, deliverable in 24h"). Only basic escrow exists.
+**Solution**: Add `ContractProposal` and `ContractAccept` tx types with terms, milestones, SLAs, and automatic penalty/reward.
+
+### GAP-7: No Governance / Voting ⚠️ LOW
+**Status**: ✅ DONE (CreateProposal + CastVote with quorum-based resolution)
+**Phase**: 4 (Decentralization)
+**Problem**: No mechanism for stakeholders to vote on protocol upgrades, parameter changes, or disputes. A network of AGI agents needs democratic governance.
+**Solution**: Add on-chain governance with proposal creation, stake-weighted voting, and automatic execution of approved proposals.
+
+### GAP-8: No Service Discovery / Pricing in Agent Metadata ⚠️ MEDIUM
+**Status**: ✅ DONE (UpdateAgentPricing tx, AgentPricing struct, /v1/pricing endpoint)
+**Phase**: 2 (Agent Economy)
+**Problem**: `AgentMeta` has name, endpoint, and capabilities — but NO pricing. An agent looking for a service provider can't compare prices. No marketplace.
+**Solution**: Add `price_per_request: Option<Amount>`, `pricing_model: Option<String>`, and `service_description: Option<String>` to `AgentMeta`.
+
+### GAP-9: No Dispute Resolution / Arbitration ⚠️ MEDIUM
+**Status**: Not started
+**Phase**: 3 (Programmability)
+**Problem**: When an escrow goes wrong (service not delivered, quality dispute), there's only refund-after-deadline. No arbitration, no partial release, no third-party mediator.
+**Solution**: Add optional `arbitrator` field to escrows. Arbitrator can release/refund/split. Integrate with reputation system.
+
+### GAP-10: No Network-Level Automation (AMM, Lending, etc.) ⚠️ LOW
+**Status**: Not started
+**Phase**: 4 (Decentralization)
+**Problem**: No automated market makers, lending pools, or DeFi primitives. Agents can't earn yield on idle BAUD or swap tokens.
+**Solution**: Phase 4 — requires smart contracts (GAP-4) first. Build DEX/AMM as first smart contract.
+
+### GAP-11: No Transaction Batching / Atomicity ⚠️ MEDIUM
+**Status**: Not started
+**Phase**: 2 (Agent Economy)
+**Problem**: Can't execute multiple transactions atomically (all-or-nothing). An AGI orchestrating a complex workflow needs atomic multi-step operations.
+**Solution**: Add `BatchTransaction` tx type that wraps multiple payloads and executes atomically.
