Authorization-zone intent/keeper framework (Issue #370). +//! +//! ## Overview +//! +//! This module allows users to issue signed, scoped, expiring **intents** that +//! authorize a nominated third-party **keeper** to perform one specific +//! permissioned action on their behalf: +//! +//! | Scope | Keeper operation | +//! |--------------|--------------------------------------------------------------| +//! | `Resolve` | Submit an oracle payload to settle the active round. | +//! | `Claim` | Withdraw the user's pending winnings to the user's account. | +//! | `CreateNext` | Spin up the next round from the admin-configured template. | +//! +//! ## Security model +//! +//! - **User custody preserved**: the `Claim` path moves funds to `user`, not +//! to the keeper. The keeper cannot redirect winnings. +//! - **Scope isolation**: a keeper granted `Resolve` cannot invoke `Claim` or +//! `CreateNext`. The contract rejects scope mismatches. +//! - **Replay protection**: every intent carries a per-`(user, scope)` nonce. +//! Consumed nonces are permanently tombstoned and never reused. +//! - **Expiry**: intents have an inclusive `expires_at_ledger`. The contract +//! rejects execution at any ledger strictly greater than that value. +//! - **Revocation**: a user may revoke any active intent before execution. +//! - **Keeper registration**: an admin may require that only explicitly +//! registered keepers are permitted to execute intents. When the flag is off +//! (the default), any keeper named in a valid intent may execute. +//! - **Pause/rate-limit respect**: all execution paths check the contract's +//! runtime mode before proceeding. +//! +//! ## Threat model +//! +//!

Overview + +The authorization-zone intent/keeper framework (Issue #370) allows users to delegate operational contract execution (such as submitting oracle settlements, claiming pending winnings, or initializing next rounds) to third-party automation keepers without transferring funds or custody of user assets. + +--- + +## 2. Assets and Trust Boundaries + +### Assets +1. **User Funds / Balances**: vXLM balances and pending winnings. +2. **Contract State**: Active rounds, pool states, and configuration parameters. +3. **Intent Nonce States**: Sequence counter tracking valid vs consumed intent nonces per user and scope. + +### Trust Assumptions +- **Contract Integrity**: Soroban VM correctly enforces `require_auth()` for signatures and storage isolation. +- **Custody Assumption**: Winnings claimed on behalf of a user MUST flow exclusively to `DataKeyScoped::Balance(user)`. Keepers have NO access to user funds. + +--- + +## 3. Threat Scenarios and Mitigations + +### 3.1 Replay Attacks (Re-submitting Consumed Intents) +- **Threat**: A rogue keeper or observer captures a signed intent from a past ledger and re-submits it to execute the action a second time. +- **Mitigation**: + - Each intent contains a unique monotonic `nonce` assigned to `(user, scope)`. + - When an intent is executed, its status is permanently updated to `Consumed` and a storage tombstone `IntentKey::ConsumedIntentNonce(user, scope, nonce)` is written with maximum storage TTL. + - Subsequent execution attempts fail with `ContractError::IntentAlreadyConsumed`. + +### 3.2 Privilege Escalation (Scope Bypassing) +- **Threat**: A keeper authorized for low-risk actions (e.g. `KeeperScope::Resolve`) attempts to use the intent to invoke higher-risk functions (e.g., claiming winnings or creating rounds). +- **Mitigation**: + - Scopes are explicitly enumerated in `KeeperScope`: `Resolve` (0), `Claim` (1), `CreateNext` (2). + - Each entry point (`execute_keeper_resolve`, `execute_keeper_claim`, `execute_keeper_create_next`) enforces an exact match between the storage intent's scope and the invoked function. + - Cross-scope calls fail with `ContractError::IntentScopeMismatch` or `ContractError::IntentNotFound`. + +### 3.3 Fund Diversion / Custody Theft +- **Threat**: A keeper executes `execute_keeper_claim` hoping to divert user winnings into the keeper's address. +- **Mitigation**: + - `execute_keeper_claim` routes directly into `crate::settlement::claim_winnings(env, user)`. + - The destination address is strictly hardcoded to `user`. Winnings are credited to `DataKeyScoped::Balance(user)` and cannot be overridden by caller parameters. + +### 3.4 Stale / Delayed Intent Execution +- **Threat**: A keeper holds a signed intent for a long duration and executes it under unfavorable market conditions. +- **Mitigation**: + - Intents carry an explicit `expires_at_ledger` field set at creation (`authorized_at_ledger + expiry_ledgers`). + - Expiry is capped between `MIN_INTENT_EXPIRY_LEDGERS` (6 ledgers / ~30 s) and `MAX_INTENT_EXPIRY_LEDGERS` (1,036,800 ledgers / ~60 days). + - At execution time, `env.ledger().sequence() > expires_at_ledger` is checked; expired intents fail with `ContractError::IntentExpired`. + - Users can explicitly revoke any active intent prior to execution via `revoke_keeper_intent`. + +### 3.5 Malicious / Unregistered Keeper Execution +- **Threat**: An arbitrary address executes user intents on public networks without authorization. +- **Mitigation**: + - The intent explicitly names `keeper: Address`. `execute_keeper_*` requires `keeper.require_auth()`. An attacker cannot execute an intent naming another keeper. + - Additionally, admins can enable `set_keeper_registration_required(true)` to restrict execution exclusively to keepers allowlisted via `register_keeper`. Unregistered keepers fail with `ContractError::KeeperNotRegistered`. + +### 3.6 Pause and Emergency Respect +- **Threat**: A keeper attempts to execute intents while the contract is emergency-paused. +- **Mitigation**: + - All entry points invoke `_ensure_not_paused(&env)` prior to state changes. + - Fully paused runtime mode (`RuntimeMode::FullyPaused`) blocks all keeper executions with `ContractError::ContractPaused`. + +--- + +## 4. Acceptance Criteria Checklist + +- [x] Expired/replayed intents rejected (`IntentExpired`, `IntentAlreadyConsumed`). +- [x] Scope cannot escalate privileges (`KeeperScope` strict checking). +- [x] User funds movement still user-authorized where required (claims route strictly to user balance). +- [x] Keeper happy paths tested (`intents.rs` test suite). +- [x] Threat model documented (`docs/INTENT_THREAT_MODEL.md`).
