This feature adds structured bounds validation — backed by +typed `EscrowError` codes — to every milestones entrypoint that accepts a +user-supplied numeric or string argument. + +Scope is limited to the milestones module (`milestones.rs`, +`milestones_consts.rs`) and the constants/types it depends on. All existing +accepted inputs must continue to be accepted; only out-of-range values are newly +rejected. + +--- + +## Glossary + +- **Milestones Entrypoints**: The public contract functions that operate on milestone + data: `release_milestone`, `refund_unreleased_milestones`, `submit_work_evidence`, + `get_milestone`, `get_milestones`, `get_milestone_approvals`, + `get_approval_deadline`, `get_work_evidence`, and `is_milestone_overdue`. +- **Milestone_Index**: A zero-based `u32` index into the milestone vector for a + given escrow contract. Valid range: `[0, milestones.len() − 1]`. +- **Work_Evidence**: A Soroban `String` submitted by the freelancer to document + completed work. Length is measured in UTF-8 bytes via `String::len()`. +- **Milestone_Indices_Vec**: A `Vec` of milestone indices supplied to + `refund_unreleased_milestones`. Must be non-empty, free of duplicates, and every + element must be a valid `Milestone_Index`. +- **EscrowError**: The `#[contracterror]` enum defined in `lib.rs`; all typed + error codes for the escrow contract live here. +- **Validator**: The bounds-validation logic inside the milestones entrypoints + (not a separate contract or module — validation runs in-line before state reads + or writes). +- **MAX_WORK_EVIDENCE_BYTES**: The maximum byte length allowed for a work-evidence + string. Currently **1 000** bytes (matching the existing guard in + `submit_work_evidence_impl`), centralised as a named constant in + `milestones_consts.rs`. +- **MIN_WORK_EVIDENCE_BYTES**: The minimum byte length for a work-evidence string. + **1** byte — empty evidence is meaningless. +- **WORK_EVIDENCE_TOO_LONG**: `EscrowError::EvidenceTooLong` — returned when + `evidence.len() > MAX_WORK_EVIDENCE_BYTES`. +- **WORK_EVIDENCE_EMPTY**: `Error::EvidenceTooLong` used for the too-long case; + the existing `Error::EvidenceTooLong` variant covers the over-limit path. For + empty evidence a distinct error (`Error::EmptyEvidence`) is introduced. + +--- + +## Requirements + +### Requirement 1: Milestone Index Bounds for `release_milestone` + +**User Story:** As a contract client or arbiter, I want `release_milestone` to +reject an out-of-range milestone index with a typed error, so that callers +receive actionable feedback and the contract never panics on an invalid index. + +#### Acceptance Criteria + +1. WHEN `milestone_index` is greater than or equal to `milestones.len()` for the + specified contract, THE Validator SHALL reject the call with + `Error::IndexOutOfBounds` before performing any auth or state mutation. +2. WHEN `milestone_index` is `u32::MAX` and the contract has fewer than + `u32::MAX + 1` milestones, THE Validator SHALL reject the call with + `Error::IndexOutOfBounds`. +3. WHEN `milestone_index` is exactly `milestones.len() − 1` (the last valid + index) and all other preconditions are met, THE Validator SHALL accept the + call and proceed with the release flow. +4. IF the contract identified by `contract_id` does not exist, THEN THE Validator + SHALL reject the call with `EscrowError::ContractNotFound` before performing + any index check. + +--- + +### Requirement 2: Milestone Index Bounds for `refund_unreleased_milestones` + +**User Story:** As a contract client, I want `refund_unreleased_milestones` to +validate every supplied milestone index against the actual milestone count, so +that partial-index vectors cannot corrupt accounting state. + +#### Acceptance Criteria + +1. WHEN `milestone_indices` is empty, THE Validator SHALL reject the call with + `EscrowError::EmptyRefundRequest` before loading any contract state. +2. WHEN `milestone_indices` contains duplicate values, THE Validator SHALL + unconditionally reject the call with `EscrowError::DuplicateMilestoneInRefund`, + regardless of whether the indices are otherwise valid. +3. WHEN any element of `milestone_indices` is greater than or equal to + `milestones.len()`, THE Validator SHALL reject the call with + `Error::IndexOutOfBounds`. +4. WHEN `milestone_indices` contains `u32::MAX` and the milestone vector has + fewer entries than `u32::MAX + 1`, THE Validator SHALL reject the call with + `Error::IndexOutOfBounds`. +5. WHEN every element of `milestone_indices` is a valid, non-duplicate index into + an unreleased, non-refunded milestone, THE Validator SHALL accept the call and + proceed with the refund flow. + +--- + +### Requirement 3: Milestone Index Bounds for `submit_work_evidence` + +**User Story:** As a freelancer, I want `submit_work_evidence` to reject an +out-of-range index with a typed error, so that the entrypoint fails safely +without state corruption. + +#### Acceptance Criteria + +1. WHEN `milestone_index` is greater than or equal to `milestones.len()` for the + specified contract, THE Validator SHALL reject the call with + `Error::IndexOutOfBounds`. +2. WHEN `milestone_index` is exactly `milestones.len() − 1` and all other + preconditions are met, THE Validator SHALL accept the call. + +--- + +### Requirement 4: Work Evidence Length Bounds for `submit_work_evidence` + +**User Story:** As a freelancer, I want `submit_work_evidence` to reject evidence +strings that are empty or exceed the protocol maximum, so that on-chain storage +is bounded and callers receive explicit typed feedback. + +#### Acceptance Criteria + +1. WHEN `evidence.len()` is `0` (empty string), THE Validator SHALL reject the + call with `Error::EmptyEvidence`. +2. WHEN `evidence.len()` is greater than `MAX_WORK_EVIDENCE_BYTES` (1 000), + THE Validator SHALL reject the call with `Error::EvidenceTooLong`. +3. WHEN `evidence.len()` is exactly `MAX_WORK_EVIDENCE_BYTES`, THE Validator + SHALL accept the call and store the evidence. +4. WHEN `evidence.len()` is exactly `1` (minimum), THE Validator SHALL accept + the call. +5. THE Milestones_Module SHALL expose `MAX_WORK_EVIDENCE_BYTES` and + `MIN_WORK_EVIDENCE_BYTES` as named `pub const` values in + `milestones_consts.rs`, so that test and governance code can reference limits + symbolically rather than by literal. + +--- + +### Requirement 5: Named Constants in `milestones_consts.rs` + +**User Story:** As a developer reviewing or testing the milestones module, I want +all protocol-level bounds to be defined as named constants in `milestones_consts.rs`, +so that limits are documented in one place and test assertions never depend on +literals. + +#### Acceptance Criteria + +1. THE Milestones_Module SHALL define `MAX_WORK_EVIDENCE_BYTES: u32 = 1_000` in + `milestones_consts.rs`. +2. THE Milestones_Module SHALL define `MIN_WORK_EVIDENCE_BYTES: u32 = 1` in + `milestones_consts.rs`. +3. FOR ALL uses of the evidence length bound in `milestones.rs`, the source SHALL + reference `MAX_WORK_EVIDENCE_BYTES` and `MIN_WORK_EVIDENCE_BYTES` rather than + inline literals. +4. WHEN the constants in `milestones_consts.rs` are changed, THE Milestones_Module + SHALL enforce the updated bounds in all entrypoints without requiring changes + to call sites beyond the constant definition. + +--- + +### Requirement 6: New `Error` Variant for Empty Evidence + +**User Story:** As an API consumer, I want a distinct typed error when I submit +an empty work-evidence string, so that I can distinguish "too long" from "empty" +without inspecting string content. + +#### Acceptance Criteria + +1. THE EscrowContract SHALL expose a new `Error::EmptyEvidence` variant in the + `Error` contracterror enum. +2. WHEN `submit_work_evidence` is called with an empty string, THE Validator SHALL + return `Error::EmptyEvidence`. +3. WHEN `submit_work_evidence` is called with a non-empty string that exceeds + `MAX_WORK_EVIDENCE_BYTES`, THE Validator SHALL return `Error::EvidenceTooLong` + (not `EmptyEvidence`). + +--- + +### Requirement 7: Preservation of All Existing Accepted Inputs + +**User Story:** As an integrator with contracts already on-chain, I want all +currently-accepted milestone entrypoint inputs to remain accepted after this +change, so that the deployment is backward-compatible. + +#### Acceptance Criteria + +1. THE Validator SHALL accept any `milestone_index` value in the range + `[0, milestones.len() − 1]` that was previously accepted before this feature. +2. THE Validator SHALL accept any `evidence` string with byte length in the range + `[1, MAX_WORK_EVIDENCE_BYTES]` that was previously accepted. +3. THE Validator SHALL accept any `milestone_indices` vector that was previously + accepted by `refund_unreleased_milestones`. +4. FOR ALL valid inputs, the Validator SHALL produce identical on-chain state + changes as the pre-validation code path (validation is purely additive — no + business logic changes). + +--- + +### Requirement 8: Test Coverage for Boundary Values + +**User Story:** As a code reviewer, I want comprehensive tests covering min, max, +zero, and over-limit values for every new validation guard, so that regressions +are caught before deployment. + +#### Acceptance Criteria + +1. THE Test_Suite SHALL include at least one test for each of the following + boundary classes for every numeric/length bound added: + - Exact minimum (accepted) + - Exact maximum (accepted) + - Zero / below minimum (rejected with correct error) + - One above maximum (rejected with correct error) +2. WHERE the system contains one or more milestones entrypoints, THE Test_Suite + SHALL include at least one regression test per entrypoint confirming that a + previously-valid input still succeeds after this change. +3. WHEN tests for `release_milestone` index bounds run, THE Test_Suite SHALL + cover `milestone_index = 0`, `milestone_index = milestones.len() − 1`, and + `milestone_index = milestones.len()` (out of bounds by 1). +4. WHEN tests for `submit_work_evidence` length bounds run, THE Test_Suite SHALL + cover evidence of length `0`, `1`, `MAX_WORK_EVIDENCE_BYTES`, and + `MAX_WORK_EVIDENCE_BYTES + 1`. +5. WHEN tests for `refund_unreleased_milestones` index bounds run, THE Test_Suite + SHALL cover an empty indices vector, a duplicate-index vector, an + out-of-bounds single index, and a valid single index. +6. THE Test_Suite SHALL be placed in a new test file + `contracts/escrow/src/test/milestones_bounds_validation.rs` and registered in + `contracts/escrow/src/test/mod.rs`. diff --git a/.vscode/settings.json b/.vscode/settings.json index c473400b..1e78dca6 100644 --- a/.vscode/settings.json +++ b/.vscode/settings.json @@ -1,3 +1,6 @@ { -

The auth chain in production is `caller.require_auth()` → - `dispute_require_arbiter`.

Pause / emergency interaction matrix for governance setters. +//! +//! Issue #742: TESTS below pin down the intended behaviour that governance +//! setters (`set_protocol_fee_bps`, `set_governed_params`, +//! `bind_settlement_token`) remain reachable in **all** three contract +//! states — **normal**, **paused**, and **emergency**. +//! +//! Unlike mutating escrow entrypoints (`create_contract`, `deposit_funds`, +//! etc.) which call `require_not_paused`, these admin-only governance +//! functions intentionally omit the pause/emergency guard so that the +//! protocol operator can adjust fees and parameters even while the +//! platform is paused or in emergency mode. +//! +//! ## What is covered +//! +//! 1. **Availability matrix** — every governance setter is called in +//! normal, paused, and emergency states and must succeed. +//! 2. **Flag independence** — `is_paused` and `is_emergency` report +//! independently: a plain `pause()` sets only `Paused`; `activate_emergency_pause()` +//! sets both; calling `is_paused()` on a purely-emergency flag returns `true`. +//! 3. **resolve_emergency clears Paused** (current behaviour) — the +//! implementation sets both `Emergency` and `Paused` to `false`, so +//! after resolution both flags read `false`. This is documented by +//! test; a future change that preserves the pause flag across +//! emergency resolution would make this test fail, drawing attention +//! to the new contract. +//! 4. **Edge cases** — double-bind protection works across all three +//! states; pause / emergency toggle idempotency. +//! +//! ## Error codes used +//! +//! | Test expects | Error variant | Code | +//! |-------------------------------|---------------------------------|------| +//! | double-bind rejection | `EscrowError::SettlementTokenAlreadyBound` | — | +//! | unpause while emergency | `Error::EmergencyActive` | 38 | +//! +//!

Token scale persistence, validation, and normalized-value helpers (#1346). +//! +//! ## Why token scale matters +//! +//! Soroban SAC tokens carry an administrator-configured `decimals` field that +//! controls how raw on-chain amounts (stroops or equivalent sub-units) map to +//! human-visible values. For example, a token with `decimals = 7` means that +//! `10_000_000` raw units equal `1.0` visible token. +//! +//! Without capturing and enforcing this scale, two failure modes exist: +//! +//! 1. **Misinterpretation** — a client denominating amounts in visible tokens +//! instead of raw units creates contracts whose milestone amounts are +//! `10^decimals` times too small. +//! 2. **Fractional remainder** — an amount that is not a whole multiple of +//! `10^decimals` cannot be represented precisely as a visible-token value, +//! so it silently loses the fractional remainder on display. +//! +//! ## Design +//! +//! * The scale (decimal count) is captured **once** at `bind_settlement_token` +//! time by calling `token::Client::decimals()` and stored under +//! [`DataKey::TokenScale`]. +//! * Every milestone amount submitted to `create_contract` is validated with +//!

Only refund milestones whose `refunded` flag is `false`. + +**Entrypoints:** `refund_unreleased_milestones` + +--- + +### `InsufficientFunds` (11) + +**When it fires:** `release_milestone` determines that the contract's available balance (`funded_amount - released_amount - refunded_amount`) is less than the milestone amount to be paid out. + +**How to avoid:** Ensure the escrow is fully funded before releasing milestones. Deposits must cover the milestone amount being released. + +**Entrypoints:** `release_milestone` + +--- + +### `AlreadyInitialized` (12) + +**When it fires:** `initialize` is called on a contract instance that already has `DataKey::Initialized == true`. + +**How to avoid:** Call `initialize` exactly once during contract deployment. Use `is_initialized` or `get_admin` to check the initialization state before calling. + +**Entrypoints:** `initialize` + +--- + +### `InsufficientAccumulatedFees` (13) + +**When it fires:** `withdraw_protocol_fees` is called with an amount that exceeds the value stored under `DataKey::AccumulatedProtocolFees`. + +**How to avoid:** Read the current accumulated fee balance before requesting a withdrawal. Never request more than is available. + +**Entrypoints:** `withdraw_protocol_fees` + +--- + +### `NotInitialized` (14) + +**When it fires:** Any lifecycle or money-flow entrypoint is called before `initialize` has been executed. All state-changing operations require initialization so that admin-controlled safety rails (pause, emergency controls, protocol fees) are always active before funds move. + +**How to avoid:** Call `initialize(admin)` once during contract setup before invoking any other entrypoint. + +**Entrypoints:** All state-changing entrypoints: `create_contract`, `deposit_funds`, `release_milestone`, `refund_unreleased_milestones`, `cancel_contract`, `issue_reputation`, `finalize_contract`, `set_arbiter`, `set_protocol_fee_bps`, `set_governed_params`, `set_contracts_parameters`, `set_max_settlement`, `withdraw_protocol_fees`, `pause`, `unpause`, `activate_emergency_pause`, `resolve_emergency` + +--- + +### `UnauthorizedRole` (15) + +**When it fires:** The caller's address does not match the role required by the entrypoint. For example: a non-client calls `deposit_funds`, a non-admin calls `set_protocol_fee_bps`, or an incorrect admin is supplied to `set_arbiter`. + +**How to avoid:** Ensure the caller's address matches the stored role. Read `get_admin` for admin-gated operations and `get_contract` for client/freelancer/arbiter roles. + +**Entrypoints:** `deposit_funds`, `release_milestone`, `set_arbiter`, `set_protocol_fee_bps`, `set_governed_params`, `set_contracts_parameters`, `set_max_settlement`, `pause`, `unpause`, `activate_emergency_pause`, `resolve_emergency`, `propose_governance_admin`, `bind_settlement_token`, `withdraw_protocol_fees` + +--- + +### `ContractPaused` (16) + +**When it fires:** Any mutating escrow operation is attempted while the admin has set the pause flag via `pause()`. + +**How to avoid:** Check `is_paused()` before calling state-changing entrypoints. Wait for the admin to call `unpause()`. + +**Entrypoints:** `create_contract`, `deposit_funds`, `release_milestone`, `refund_unreleased_milestones`, `cancel_contract`, `issue_reputation`, `set_arbiter` + +--- + +### `EmergencyActive` (17) + +**When it fires:** Any mutating escrow operation is attempted while the admin has set the emergency flag via `activate_emergency_pause()`. + +**How to avoid:** Check `is_emergency()` before calling state-changing entrypoints. Wait for the admin to call `resolve_emergency()`. + +**Entrypoints:** `create_contract`, `deposit_funds`, `release_milestone`, `refund_unreleased_milestones`, `cancel_contract`, `issue_reputation` + +--- + +### `InvalidState` (18) + +**When it fires:** A lifecycle operation is called on a contract that is not in the expected status.

The latter event + is not evidence that client state changed, because the implementation makes + no such write. +- `issue_reputation` emits no event. + +The helper emitters in `contracts/escrow/src/events.rs` are not called by these +production entrypoints and are not enforcement evidence. + +## Source-audit limits and non-guarantees + +The following findings delimit the invariants above: + +1. **The active source currently has compile blockers.** Examples include + duplicate error variants/discriminants, missing `MilestoneEntry`, + `EventInput`, `MAX_EVENT_BATCH_SIZE`, and `status_index`, missing root + constant/type re-exports, nonexistent `DataKey::MaxMilestones`, and the + public `resolve_dispute` treating `DisputeInfo` as a tuple. + +2. **There is no canonical milestone storage key.** Creation, deposit, several + getters, and finalization use + `(DataKey::Contract(id), Symbol("milestones"))`; `ttl::load_milestones`, + `ttl::store_milestones`, approvals, and several mutation paths use + `DataKey::Milestones(id)`. Consequently the current public creation path + does not establish the storage shape expected by release/refund helpers. + +3. **There is no repository-enforced token-balance conservation equation.** + Custody is pooled in one external token contract, accumulated fees are + global, and no entrypoint reconciles the actual token balance with internal + records. `resolve_dispute` changes accounting without transferring tokens. + +4. **Some counters lack overflow protection.** Reputation counts, total + ratings, and pending-credit increments use + unchecked `+=`/`+ 1` arithmetic, so the source does not establish an + unbounded overflow-safety invariant for those counters. + +5. **The code does not implement a checks-effects-interactions ordering + guarantee.** Deposit, release, refund, and cancellation call the external + token before persisting their corresponding accounting effects. Transaction + rollback on failure is a Soroban host property, not a local reentrancy guard. + +6. **The token probe is an interface call, not an asset-authenticity proof.** + Any contract that successfully implements the called `balance` interface can + pass it. The source directly invokes the call and does not translate a panic + into the documented `InvalidSettlementToken` error. + +7. **Generic events are not state attestations.** Any authenticated address can + call `emit_event` or its batch variants with arbitrary topic/data; no + participant or admin role is required. + +8. **No upgrade invariant exists.** There is no active Wasm-upgrade, deployer, + Wasm-hash, general state-migration, or reputation-storage-migration + entrypoint. Likewise, there are no vault, allocation-strategy, nester, or + separate treasury contracts in this workspace. + +9. **Undeclared source files do not enforce contract behavior.** In particular, + `authorization.rs`, `contracts.rs`, `milestones.rs`, `release.rs`, + `refund.rs`, `refund_impl.rs`, `settlement.rs`, and + `reputation_migration.rs` are not in the active module graph and are not + cited above. + +## Supporting tests + +Tests supplement, but do not replace, the source audit.

Reviewer Checklist for Storage Changes + +When introducing a new storage key, make sure all of the following are +addressed before landing: + +1. Add the variant to `DataKey` in `types.rs`, or use a compound tuple key + if the key depends on a sub-identifier (e.g. the milestone vector's + `(Contract(id), Symbol("milestones"))` pattern). +2. Decide between `persistent()` and `temporary()`. Use temporary for + anything that must auto-expire without an explicit cleanup call + (approvals, proposals, short-lived permissions). Use persistent for + accounting / governance / immutable records. +3. For temporary entries: pick a TTL, bump threshold, add a row to §4 + above, and use `store_with_ttl` + `read_if_live` uniformly (no direct + `.set` bypass). +4. For persistent entries: decide if / when TTL is extended and use one of + the `extend_*_ttl` helpers consistently. Document any "deliberately not + bumped" exceptions (e.g. `contract_exists`, `is_settlement_token_bound`). +5. Add a storage test that writes then reads back, and — for + temporary entries — a TTL eviction test that advances ledger sequence + past TTL + 1 and asserts `None`. +6.

Trust Assumptions + +| Entity / Component | Trust Level | Scope of Trust & Operational Constraints | +|---|---|---| +| **Governance Admin (`admin`)** | Semi-Trusted | - Authorized to execute operational safety controls: `pause`, `unpause`, `activate_emergency_pause`, `resolve_emergency`, and governance parameter setup.
- Can initiate and manage two-step governance admin proposals (`propose_governance_admin`, `accept_governance_admin`).
- **Constraint**: Cannot directly drain escrowed milestone funds to an arbitrary address without following standard contract lifecycle or dispute resolution logic. | +| **Arbiter (`arbiter`)** | Semi-Trusted | - Assigned per-contract or governed to resolve disputes (`resolve_dispute`) and approve releases in `ArbiterOnly` or `ClientAndArbiter` modes.
- **Constraint**: Dispute resolution is bounded by `client_amount + freelancer_amount <= available_balance`. Cannot award funds beyond the escrowed amount. | +| **Client (`client`)** | Untrusted | - Authorized to create contracts, deposit funds, approve milestone releases (in `ClientOnly`, `ClientAndArbiter`, `MultiSig` modes), request refunds of unreleased milestones on non-terminal contracts, and request client migration.
- **Constraint**: Cannot withdraw funds allocated to released milestones or drain other clients' escrow balances. | +| **Freelancer (`freelancer`)** | Untrusted | - Authorized to approve milestone releases (in `MultiSig`), trigger releases post-approval, cancel unfunded contracts, and open disputes.
- **Constraint**: Cannot release funds without required authorization/approvals. | +| **Soroban Host Environment & SAC** | Fully Trusted | - Trusted to enforce cryptographic signature verification via `require_auth()`, manage storage isolation, execute atomic SAC token transfers, and manage storage Time-To-Live (TTL). | + +--- + +## 3. Attacker Capabilities & Threat Vectors + +### 3.1 Unauthenticated External Attacker +- **Threat Vector**: Submitting transactions to invoke administrative or lifecycle functions without valid key signatures. +- **Attacker Capability**: Can inspect public ledger state, send arbitrary contract invocations, and attempt to call `pause`, `deposit_funds`, `release_milestone`, `refund_unreleased_milestones`, or `resolve_dispute`. +- **Mitigation**: Soroban host cryptographic validation. All mutating functions enforce `require_auth()` on the target address (`admin`, `client`, `freelancer`, `arbiter`, or `caller`), causing unauthenticated calls to revert immediately. + +### 3.2 Malicious / Rogue Client +- **Threat Vector**: Reclaiming deposited funds post-release, creating contracts with invalid milestone configurations, overfunding contracts, or issuing duplicate reputation ratings. +- **Attacker Capability**: Has valid client key signatures for contracts they created. +- **Mitigation**: + - Milestone amount bounds checking (`[1, 1_000_000_0000000]` stroops) and checked summation (`accumulate_amounts`) prevent overflow and invalid contract totals. + - Strict deposit validation ensures deposits match exact milestone expectations without overfunding. + - State machine checks prevent refunds after finalization, completion, or cancellation (`AlreadyFinalized`, `ContractCancelled`, `ContractRefunded`). + - Reputation issuance enforces `Completed` state and single-use `reputation_issued` flags (`AlreadyIssued`). + +### 3.3 Malicious / Compromised Freelancer +- **Threat Vector**: Attempting unauthorized milestone releases, draining escrow balances before completing work, or blocking contract cancellation. +- **Attacker Capability**: Has valid freelancer key signatures for assigned contracts. +- **Mitigation**: + - `release_milestone` enforces mode-specific authorization (`ReleaseAuthorization` matrix) and checks non-expired approval records via `check_approvals`. + - In `MultiSig` mode, release requires both client and freelancer signed approvals. + - State machine requires `Funded` status for milestone releases and disputes. + +### 3.4 Rogue / Compromised Arbiter +- **Threat Vector**: Arbitrarily resolving non-disputed contracts or allocating more than the total deposited balance. +- **Attacker Capability**: Has valid arbiter key signatures. +- **Mitigation**: + - `resolve_dispute` is restricted strictly to contracts in the `Disputed` state. + - Enforces `client_amount + freelancer_amount <= available_balance` via checked arithmetic (`safe_subtract_amounts`). + - Finalized contracts block dispute resolution (`AlreadyFinalized`). + +### 3.5 Reentrancy & Stale Approval Re-use +- **Threat Vector**: Re-using milestone approval signatures or exploiting reentrancy during token transfers. +- **Attacker Capability**: Re-submitting approval signatures or manipulating contract callback order. +- **Mitigation**: + - Approval records are cleared (`clear_approvals`) immediately upon milestone release. + - Approvals stored in temporary storage expire automatically after `PENDING_APPROVAL_TTL_LEDGERS` (~7 days). `check_approvals` fails closed (`InsufficientApprovals`) if approvals are missing or expired. + - Soroban's execution engine prevents traditional EVM-style reentrancy across contract calls. + +--- + +## 4. Security Mitigations & System Guardrails + +1. **Authentication & Authorization Gating**: Every mutating function enforces `require_auth()` on the required identity before state changes occur. +2. **State Machine Strictness**: Contracts transition through explicit states: `Created` → `Funded` → (`Completed` | `Disputed` | `Cancelled` | `Refunded`). Terminal states block further value-moving operations. +3. **Checked Arithmetic & Invariant Conservation**: + - All financial balance additions and subtractions use checked arithmetic (`checked_add`, `checked_sub`, `accumulate_amounts`, `safe_subtract_amounts`). + - Escrow balance conservation invariant is maintained at all state boundaries: + $$\text{total\_deposited} == \text{released\_amount} + \text{refunded\_amount} + \text{available\_balance}$$ +4. **Emergency & Pause Safeguards**: + - `pause` and `activate_emergency_pause` immediately halt mutating operations (`ContractPaused`, `EmergencyActive`). + - Pause checks execute alongside/prior to state mutations. +5. **Fail-Closed Storage & Expiry**: + - Un-acted temporary approval entries auto-evict via TTL. Missing/evicted entries fail closed (`InsufficientApprovals`). + - Finalization state is recorded in persistent storage to prevent record loss via TTL eviction. + +--- + +## 5.

Per Soroban's semantics, -this only actually extends the entry's TTL if its *current* remaining TTL is -below `threshold` (7 days); otherwise it's a no-op. This means a contract -under active dispute back-and-forth doesn't get its TTL churned on every -call — only entries that are actually getting close to expiry are renewed. - -**`extend_contract_ttl` is called twice in each dispute entrypoint** — once -immediately after reading the contract, and again immediately after writing -it back: - -```rust -// raise_dispute (contracts/escrow/src/lib.rs) -let mut contract: Contract = env.storage().persistent() - .get(&DataKey::Contract(contract_id)) - .unwrap_or_else(|| env.panic_with_error(Error::ContractNotFound)); - -ttl::extend_contract_ttl(&env, contract_id); // bump #1: on read -Self::require_not_finalized(&env, contract_id); - -// ... validation ... - -contract.status = ContractStatus::Disputed; -env.storage().persistent().set(&DataKey::Contract(contract_id), &contract); - -ttl::extend_contract_ttl(&env, contract_id); // bump #2: on write -``` - -`resolve_dispute` follows the identical pattern: read → bump → validate → -mutate → write → bump. In practice this means any successful call to either -entrypoint gives the contract's persistent entry the best chance of renewal -available under the bump-on-read/write pattern, since it's checked both -before and after the state mutation. - -## Eviction risk - -If a contract's persistent entry is never touched by any entrypoint for -longer than `PERSISTENT_TTL_LEDGERS` (30 days), Soroban's host will evict it. -A dispute cannot be raised or resolved on an evicted contract — the initial -`env.storage().persistent().get(...)` in either entrypoint returns `None`, -and the entrypoint panics with `Error::ContractNotFound`, identical to the -entry never having existed at all. There is no special recovery path for a -disputed contract that has been evicted; this is the same fail-closed -behavior `ttl.rs`'s own module documentation describes for all persistent -entries. - -## Gating on finalization - -Both entrypoints call `Self::require_not_finalized(&env, contract_id)` -immediately after the TTL bump-on-read, before any dispute-specific -validation. This checks for the *presence* of `DataKey::Finalization(contract_id)` -(see `contracts/escrow/src/finalize.rs`) — a separate persistent key, owned by -the `finalize` module, not by disputes. If that key exists, both entrypoints -panic with `Error::AlreadyFinalized`. Disputes never read or write the -finalization key's value directly; they only cause `require_not_finalized` -to check whether it's present. - -## Side effect on reputation storage - -When `resolve_dispute` results in `ContractStatus::Completed`, it calls -`grant_pending_reputation_credit`, which reads and writes -`DataKey::PendingReputationCredits(freelancer_address)` (persistent), -incrementing a pending-credit counter by one. This is a real side effect of -resolving a dispute, so it's noted here for completeness — but it is **not** -part of the disputes storage domain; `PendingReputationCredits` is owned by -the reputation system. - -Worth flagging separately: at the time of writing, no code path anywhere in -the crate calls an explicit TTL-extend on `PendingReputationCredits` — not in -`resolve_dispute`, nor in the other two call sites (`lib.rs:1737`, -`release.rs:125`). This key relies entirely on whatever default TTL Soroban -assigns on `.set()`, with no renewal. This is a pre-existing characteristic -of the reputation system, unrelated to the dispute flow's own TTL handling, -and out of scope for this document — flagged here only because it's visible -from the dispute code path. - -## Events (not storage) - -Both entrypoints publish events — `("dispute", "opened")` from -`raise_dispute` and `("dispute", "resolved")` from `resolve_dispute` — for -off-chain indexers.

Off-chain vetting is the primary defense. +- `Split` amounts must exactly equal the available balance (`InvalidDisputeSplit` error). The arbiter cannot extract more than the escrow holds. +- `resolution_payouts()` computes payouts from the accounting invariant: `available = funded_amount - released_amount - refunded_amount`. No new funds are created. +- After resolution, `finalize_contract` writes an immutable `FinalizationRecord` with the arbiter's address, timestamp, and full accounting snapshot, creating a permanent audit trail. + +**Residual risk:** Medium. On-chain enforcement guarantees accounting correctness but cannot guarantee fairness of the arbiter's subjective decision. Off-chain reputation and legal agreements are the complementary mitigation. + +### A3: Compromised client or freelancer raises a frivolous dispute + +**Capability:** A party whose key is compromised raises a dispute on a healthy contract to freeze operations. + +**Mitigations:** +- `raise_dispute` transitions the contract to `Disputed`, which **blocks** `release_milestone` (cross-ref: `test/dispute.rs:246` `release_is_blocked_while_disputed`). +- `cancel_contract` is also blocked in `Disputed` state (`InvalidStatusTransition`). Cross-ref: `test/cancel_contract.rs:451-515`. +- The arbiter can resolve the dispute through `resolve_dispute`, restoring funds to either party. +- If the arbiter is unresponsive, finalization via `finalize_contract` from `Disputed` state writes an immutable record. The contract remains in `Disputed` until resolved or finalized. + +**Residual risk:** Medium. A compromised party can temporarily freeze operations. The arbiter and finalization provide recovery paths but introduce delay. + +### A4: Admin freezes disputes via pause + +**Capability:** The admin calls `pause()` to block all mutating operations including `raise_dispute` and `resolve_dispute`. + +**Mitigations:** +- Pause and unpause require `admin.require_auth()`. +- Emergency pause additionally sets `Emergency` flag, which blocks `unpause()` until `resolve_emergency()` is called by the admin. +- Paused state is a circuit breaker, not a resolution mechanism. It does not change fund accounting. +- Tests confirm: `pause_blocks_raise_and_resolve_dispute` (cross-ref: `test/dispute.rs:265`). + +**Residual risk:** Low. Admin abuse is an operational risk mitigated by off-chain governance and the two-step admin transfer (planned: #318). + +### A5: Double-spend or accounting manipulation during dispute resolution + +**Capability:** An attacker attempts to extract more funds than the escrow holds, or manipulate accounting during resolution. + +**Mitigations:** +- `resolution_payouts()` computes `available = funded_amount - released_amount - refunded_amount` using checked subtraction.

Overview + +The TalentTrust escrow contract manages milestone-based payments, client migrations, dispute resolution, reputation scoring, and protocol governance on Soroban (Stellar). To protect user funds and maintain system safety, every state-modifying entrypoint enforces strict authorization guards using: + +1. **Soroban `require_auth()` Authentication**: Ensures transactions are cryptographically signed by the required participant address before any state mutation occurs. +2. **Role-Based Authorization**: Restricts function execution to specific roles (Governance Admin, Client, Freelancer, Arbiter, Proposed Admin, or Proposed Client). +3. **State Machine Guardrails**: Enforces valid `ContractStatus` transitions (e.g. `Created` → `Funded` → `Completed`) and rejects invalid state mutations. +4. **Emergency & Pause Controls**: Provides global system freeze capabilities (`Paused`, `EmergencyActive`) that halt all money movement and state modifications. +5. **Contract Finalization**: Locks completed/disputed contracts against any further mutations (`AlreadyFinalized`). + +--- + +## 2.

Check Approvals (`check_approvals`) - -**Entry Point**: `contracts/escrow/src/approvals.rs::check_approvals` - -**Purpose**: Validates that sufficient approvals exist for a milestone release. - -**Behavior**: -- Loads approvals from temporary storage -- Returns `None` if approvals don't exist or have expired (TTL elapsed) -- Checks approval sufficiency based on `ReleaseAuthorization` mode - -**Approval Sufficiency Logic**: -```rust -match contract.release_authorization { - ReleaseAuthorization::ClientOnly => approvals.client_approved, - ReleaseAuthorization::ArbiterOnly => approvals.arbiter_approved, - ReleaseAuthorization::ClientAndArbiter => { - approvals.client_approved || approvals.arbiter_approved - } - ReleaseAuthorization::MultiSig => { - approvals.client_approved && approvals.freelancer_approved - } -} -``` - -**Error Codes**: -- `InsufficientApprovals`: Approvals missing, insufficient, or expired - -**Security Properties**: -- Fail-closed: expired approvals are treated as absent -- TTL expiry is enforced by Soroban's temporary storage (automatic eviction) - -### 3. Release Milestone (`release_milestone`) - -**Entry Point**: `contracts/escrow/src/lib.rs::release_milestone` - -**Purpose**: Executes the fund transfer to the freelancer for a specific milestone. - -**Prerequisites**: -- Contract must exist and be in `Funded` state -- Caller must be authenticated via `require_auth()` -- Caller must be authorized to release based on the `ReleaseAuthorization` mode -- Valid, non-expired approvals must exist (checked via `check_approvals`) -- Milestone must not already be released or refunded -- Sufficient funds must be available - -**Release Authorization Check**: -```rust -match contract.release_authorization { - ReleaseAuthorization::ClientOnly => { - if !is_client { return Err(Error::UnauthorizedRole); } - } - ReleaseAuthorization::ArbiterOnly => { - if !is_arbiter { return Err(Error::UnauthorizedRole); } - } - ReleaseAuthorization::ClientAndArbiter => { - if !is_client && !is_arbiter { return Err(Error::UnauthorizedRole); } - } - ReleaseAuthorization::MultiSig => { - if !is_client && !is_freelancer { return Err(Error::UnauthorizedRole); } - } -} -``` - -**Error Codes**: -- `ContractNotFound`: Contract does not exist -- `InvalidState`: Contract not in `Funded` state -- `IndexOutOfBounds`: Milestone index invalid -- `MilestoneAlreadyReleased`: Milestone already released -- `AlreadyRefunded`: Milestone already refunded -- `InsufficientFunds`: Insufficient contract balance -- `InsufficientApprovals`: Required approvals missing or expired -- `UnauthorizedRole`: Caller not authorized to release for this mode - -**Side Effects**: -- Transfers milestone amount to freelancer -- Marks milestone as released -- Updates contract `released_amount` -- Accumulates protocol fees if configured -- Transitions contract to `Completed` if all milestones released/refunded -- Clears approval records (see below) - -### 4. Clear Approvals (`clear_approvals`) - -**Entry Point**: `contracts/escrow/src/approvals.rs::clear_approvals` - -**Purpose**: Removes approval records after successful release to prevent reuse. - -**Behavior**: -- Removes the `MilestoneApprovals` entry from temporary storage -- Called automatically after successful `release_milestone` - -**Security Properties**: -- Prevents approval reuse across multiple releases -- Cleans up temporary storage -- Idempotent: safe to call multiple times - -## TTL Expiry Behavior - -### Pending Approval TTL - -Pending approvals are stored in Soroban's temporary storage with a time-to-live (TTL) policy defined in `contracts/escrow/src/ttl.rs`: - -**Constants**: -```rust -pub const LEDGERS_PER_DAY: u32 = 17_280; -pub const PENDING_APPROVAL_TTL_LEDGERS: u32 = LEDGERS_PER_DAY * 7; // ~7 days -pub const PENDING_APPROVAL_BUMP_THRESHOLD: u32 = LEDGERS_PER_DAY; // ~1 day -``` - -**Expiry Window**: 120,960 ledgers (~7 days at ~5s per ledger on mainnet) - -**TTL Extension Logic**: -- When an approval is recorded, TTL is set to `PENDING_APPROVAL_TTL_LEDGERS` -- When the approval entry is accessed above the bump threshold, TTL is extended back to the full `PENDING_APPROVAL_TTL_LEDGERS` -- If the entry is not accessed before TTL elapses, Soroban auto-evicts it - -**Interaction with Release**: -- Expired approvals are indistinguishable from never-set approvals (both return `None`) -- `check_approvals` treats expired approvals as insufficient and returns `InsufficientApprovals` -- This provides a fail-closed security property: expired approvals cannot be used to release funds - -**Recovery from Expiry**: -- If approvals expire, all parties must re-approve the milestone -- This prevents stale approvals from being used long after they were granted -- Integrators should monitor approval TTL and re-approve before expiry if needed - -## Complete Flow Example - -### ClientOnly Mode Flow - -1. **Client calls** `approve_milestone_release(contract_id, client_address, milestone_index)` - - Approval recorded: `client_approved = true` - - TTL set to 7 days - -2. **Client calls** `release_milestone(contract_id, client_address, milestone_index)` - - Caller authorization check: client is authorized ✓ - - Approval check: `client_approved = true` ✓ - - Funds transferred to freelancer - - Approval cleared - -### MultiSig Mode Flow - -1. **Client calls** `approve_milestone_release(contract_id, client_address, milestone_index)` - - Approval recorded: `client_approved = true` - - TTL set to 7 days - - Approval check fails: `client_approved && freelancer_approved = false` → `InsufficientApprovals` - -2. **Freelancer calls** `approve_milestone_release(contract_id, freelancer_address, milestone_index)` - - Approval recorded: `freelancer_approved = true` - - TTL extended to 7 days - - Approval check passes: `client_approved && freelancer_approved = true` ✓ - -3. **Either client or freelancer calls** `release_milestone(contract_id, caller_address, milestone_index)` - - Caller authorization check: client or freelancer is authorized ✓ - - Approval check: both approved ✓ - - Funds transferred to freelancer - - Approval cleared - -## Error Code Reference - -| Error Code | Value | When Raised | -|------------|-------|-------------| -| `UnauthorizedRole` | 10, 11 | Caller not authorized for approval or release in current mode | -| `AlreadyApproved` | 18 | Caller already approved this milestone (duplicate approval) | -| `InsufficientApprovals` | 19, 20 | Required approvals missing, insufficient, or expired | -| `MissingArbiter` | 2 | Arbiter required but not provided (ArbiterOnly or ClientAndArbiter modes) | -| `InvalidArbiter` | 3 | Arbiter is same as client or freelancer | -| `ContractNotFound` | 9 | Contract does not exist | -| `InvalidState` | 11, 16 | Contract not in `Funded` state | -| `IndexOutOfBounds` | 3, 12 | Milestone index invalid | -| `MilestoneAlreadyReleased` | 13, 17 | Milestone already released | - -## Security Considerations - -### Fail-Closed Design - -- Missing approvals prevent release (`InsufficientApprovals`) -- Expired approvals prevent release (treated as missing) -- Unauthorized callers are rejected (`UnauthorizedRole`) -- Duplicate approvals are rejected (`AlreadyApproved`) - -### Authentication - -- All approval and release operations require `require_auth()` -- Soroban's native authentication ensures the caller is who they claim to be - -### Approval Isolation - -- Approvals are stored per-milestone, not per-contract -- Clearing approvals after release prevents reuse -- TTL expiry prevents stale approvals from being used - -### Mode-Specific Guarantees - -- **ClientOnly**: Only client can approve/release, ensuring client control -- **ArbiterOnly**: Only arbiter can approve/release, enabling dispute resolution -- **ClientAndArbiter**: Either can approve/release, providing flexibility -- **MultiSig**: Both must approve, ensuring mutual agreement before release -

It covers every principal role, the per-entrypoint authorization rules, the four `ReleaseAuthorization` modes and their approval lifecycle, the invariants the model upholds, and a worked end-to-end example an auditor can follow. + +**Source files:** `contracts/escrow/src/types.rs`, `contracts/escrow/src/approvals.rs`, `contracts/escrow/src/release.rs`, `contracts/escrow/src/deposit.rs`, `contracts/escrow/src/finalize.rs`, `contracts/escrow/src/create_contract.rs`, `contracts/escrow/src/governance.rs`, `contracts/escrow/src/lib.rs` + +--- + +## 1. Principal Roles + +The contract recognizes four principal roles. Each maps to a stored address on the `Contract` struct or on the global admin slot. + +| Role | Storage field | Scope | Notes | +|------|--------------|-------|-------| +| **Admin** | `DataKey::Admin` (persistent) | Protocol-wide | Set once by `initialize`; can be rotated via a two-step timelock | +| **Client** | `Contract.client` | Per-contract | Set at `create_contract`; may change via `propose_client_migration` / `accept_client_migration` | +| **Freelancer** | `Contract.freelancer` | Per-contract | Set at `create_contract`; immutable | +| **Arbiter** | `Contract.arbiter` (optional) | Per-contract | Required for `ArbiterOnly` and `ClientAndArbiter` modes; must be distinct from client and freelancer | + +The arbiter field is `Option
`. An absent arbiter means the contract cannot use arbiter-gated authorization modes. Attempting to create a contract with `ArbiterOnly` or `ClientAndArbiter` mode without providing an arbiter panics with `MissingArbiter`. + +--- + +## 2. Entrypoint Authorization Table + +Every state-changing entrypoint that can move funds or mutate contract state is listed below. "Required signer" is the address the Soroban host checks via `require_auth()`. Entrypoints not listed here are read-only and require no auth. + +### Admin-gated entrypoints + +All of these require the address stored under `DataKey::Admin` to have authorized the call. + +| Entrypoint | Required signer | Additional preconditions | +|-----------|----------------|--------------------------| +| `initialize(admin)` | `admin` (the passed argument) | Fails with `AlreadyInitialized` if already run | +| `bind_settlement_token(admin, token)` | `admin` == stored admin | Contract must be initialized; token must not already be bound; token must pass SAC probe | +| `pause()` | Stored admin | Contract must be initialized | +| `unpause()` | Stored admin | Contract must be initialized; blocked while emergency flag is set | +| `activate_emergency_pause()` | Stored admin | Contract must be initialized | +| `resolve_emergency()` | Stored admin | Contract must be initialized | +| `set_protocol_fee_bps(new_bps)` | Stored admin | Contract initialized; `new_bps ≤ 10_000` | +| `set_governed_params(admin, fee_bps, max_stroops)` | `admin` == stored admin | Contract initialized; `fee_bps ≤ 10_000` | +| `propose_admin(proposed)` | Stored admin | Contract initialized; `proposed` must not equal the stored admin (`CannotProposeSelf`) | +| `accept_admin()` | The pending proposed admin | Timelock of `ADMIN_ROTATION_MIN_DELAY_LEDGERS` (≈ 2 days) must have elapsed since `propose_admin`, and no more than `ADMIN_ROTATION_PROPOSAL_TTL_LEDGERS` (≈ 9 days) | +| `cancel_admin()` | Stored admin | A pending proposal must exist (expired proposals may still be cancelled) | +| `withdraw_protocol_fees(admin, amount)` | Stored admin | Settlement token must be bound; `AccumulatedProtocolFees ≥ amount` | + +### Contract-lifecycle entrypoints + +| Entrypoint | Required signer | Authorized role(s) | Additional preconditions | +|-----------|----------------|--------------------|--------------------------| +| `create_contract(client, freelancer, arbiter, milestones, mode)` | `client` | Client | Contract not paused; participants valid; milestones valid | +| `deposit_funds(contract_id, caller, amount)` | `caller` == `contract.client` | Client only | Contract initialized, not paused; status `Created` or `PartiallyFunded`; amount ≤ remaining unfunded total | +| `approve_milestone_release(contract_id, caller, milestone_index)` | `caller` | Mode-dependent (see §3) | Contract not paused, not finalized; status `Funded` or `PartiallyFunded`; milestone not released | +| `release_milestone(contract_id, caller, milestone_index)` | `caller` | Mode-dependent (see §3) | Contract not paused, not finalized; status `Funded`; valid non-expired approvals present | +| `refund_unreleased_milestones(contract_id, milestone_indices)` | `contract.client` | Client only | Contract not paused, not finalized; status `Created`, `Funded`, or `Disputed`; milestones meet deadline/overdue rules | +| `cancel_contract(contract_id, client)` | `client` == `contract.client` | Client only | Contract not paused, not finalized; status `Created` or `Funded`; `released_amount == 0` | +| `finalize_contract(contract_id, finalizer)` | `finalizer` | Client, freelancer, or arbiter | Contract not paused; status `Completed` or `Disputed`; not already finalized | +| `issue_reputation(contract_id, caller, rating, comment)` | `caller` == `contract.client` | Client only | Contract not paused; status `Completed`; reputation not yet issued; rating in [1,5] | +| `propose_client_migration(contract_id, current_client, new_client)` | `current_client` == `contract.client` | Current client | Contract not paused | +| `accept_client_migration(contract_id, new_client)` | `new_client` | Proposed new client | Contract not paused; live pending migration must exist | +| `resolve_dispute(contract_id, arbiter, resolution)` | `arbiter` | Arbiter only | Contract not paused; status `Disputed`; arbiter must be set and match | + +### Global gate applied before all state-changing entrypoints + +Before any of the above entrypoints reads or mutates contract state, `require_not_paused` checks both the `Paused` flag and the `Emergency` flag. If either is `true`, the call panics with `ContractPaused` or `EmergencyActive` respectively. This gate runs before `require_auth()` on the participant for lifecycle entrypoints, meaning a paused contract cannot be interacted with even by authorized principals. + +--- + +## 3.

The client identity check runs before the SAC transfer so a rejected deposit cannot debit the caller. + +**Source:** `deposit.rs::validate_deposit` line: `if caller != &contract.client`. + +### I3 — Release callers are mode-restricted + +`release_milestone` re-checks the caller's role against `contract.release_authorization` independently of `approve_milestone_release`. Even if approvals are present in storage, an unauthorized caller cannot trigger a release. + +**Source:** `lib.rs::release_milestone` — the `match contract.release_authorization` block runs before `check_approvals`. + +### I4 — Approvals are mode-restricted at record time + +`approve_milestone_release` performs a role check before recording any approval. An arbiter cannot record a `client_approved = true` bit, and a freelancer cannot approve in `ClientOnly` or `ArbiterOnly` modes. + +**Source:** `approvals.rs::approve_milestone` — the second `match contract.release_authorization` block. + +### I5 — Approvals expire automatically + +Approval records live in temporary storage.

If `elapsed > ADMIN_ROTATION_PROPOSAL_TTL_LEDGERS` (≈9 days), it panics with `AdminProposalExpired` instead — since a panic rolls back all state, the stale proposal is left in place and must be cleared with `cancel_admin` or replaced with a fresh `propose_admin`.

Post-Upgrade Verification - -Immediately after the upgrade, verify that all state is intact and the new -binary is functional. - -### 4.1 Identity Verification Checklist - -Assert that the following values are **unchanged** from the pre-upgrade -snapshot: - -```bash -# Admin must be unchanged -ADMIN=$(soroban contract invoke --id -- get_admin) -# Compare with pre-upgrade value - -# Settlement token must be unchanged -TOKEN=$(soroban contract invoke --id -- get_settlement_token) -# Compare with pre-upgrade value - -# Protocol fee must be unchanged -FEE=$(soroban contract invoke --id -- get_protocol_fee_bps) -# Compare with pre-upgrade value - -# Next contract ID must be >= pre-upgrade value -NEXT_ID=$(soroban contract invoke --id -- get_next_contract_id) -# Compare with pre-upgrade value (should be identical unless a contract was created during upgrade) -``` - -### 4.2 Readiness Checklist Verification - -```bash -soroban contract invoke \ - --id \ - -- \ - get_mainnet_readiness_info -``` - -Expected: all three flags (`initialized`, `governed_params_set`, -`emergency_controls_enabled`) remain `true`. - -### 4.3 Live Contract State Verification - -For each in-flight contract identified in step 1.3, verify the state is -unchanged: - -```bash -soroban contract invoke \ - --id \ - -- \ - get_contract --contract_id -``` - -Compare status, funded_amount, released_amount, and refunded_amount against -pre-upgrade records. - -### 4.4 Functional Smoke Test - -Perform a minimal read-only operation using the new binary: - -```bash -soroban contract invoke \ - --id \ - -- \ - get_bounds -``` - -This verifies the new WASM compiles and executes correctly on the host. - ---- - -## 5.

Rollback Procedure - -If the post-upgrade verification fails (step 4), the operator must roll back to -the previous WASM binary. - -### 6.1 Rollback Steps - -1. **Do NOT unpause** — the contract should remain in emergency pause state. -2. **Re-install the previous WASM binary** using the same upload and upgrade - procedure from step 3, but with the original `.wasm` file. -3. **Re-run the post-upgrade verification checklist** (step 4) against the - rolled-back binary. -4. If verification passes, proceed to unpause (step 5). -5. If verification still fails, **keep the contract paused** and investigate - the storage state manually. Contact the protocol team. - -### 6.2 Rollback Timeline - -- The emergency pause prevents all state changes, so there is no urgency to - complete the rollback within a specific timeframe. -- However, in-flight contracts with deadlines may be affected. Monitor for - deadline-based refunds (`claim_timeout_refund`) that clients may initiate once - operations resume. - ---- - -## 7. Storage Layout: Migration vs Plain Code Swap - -### 7.1 Plain Code Swap (No Migration Required) - -The current escrow contract (V1 layout) uses a **plain code swap** for -upgrades. The following storage entries are unaffected by a WASM binary -replacement: - -| Storage Key | Namespace | Affected by Code Swap? | -|---|---|---| -| `DataKey::Initialized` | persistent | No — persists across swaps | -| `DataKey::Admin` | persistent | No | -| `DataKey::Paused` | persistent | No | -| `DataKey::Emergency` | persistent | No | -| `DataKey::Contract(id)` | persistent | No | -| `DataKey::NextContractId` | persistent | No | -| `DataKey::SettlementToken` | persistent | No | -| `DataKey::ProtocolFeeBps` | persistent | No | -| `DataKey::GovernedParameters` | persistent | No | -| `DataKey::ReadinessChecklist` | persistent | No | -| `DataKey::AccumulatedProtocolFees` | persistent | No | -| `DataKey::Reputation(addr)` | persistent | No | -| `DataKey::PendingReputationCredits(addr)` | persistent | No | -| `DataKey::MilestoneApprovals(id, idx)` | temporary | No — auto-evicted by host | -| `DataKey::PendingClientMigration(id)` | temporary | No — auto-evicted by host | - -**Key insight**: All live contract state is stored in Soroban persistent or -temporary storage keyed by stable `DataKey` variants. Replacing the WASM binary -does not clear or alter on-ledger storage entries. The new binary reads the same -keys and interprets them identically. - -### 7.2 When a Storage Migration IS Required - -A storage migration step is required when: - -1. **New `DataKey` variants are added** — if the new WASM introduces a new - variant (e.g. `DataKey::V2Metadata`), existing storage entries under V1 keys - are unaffected, but any new feature that reads from the V2 key will find - nothing. A migration function can initialise V2 defaults. - -2. **Existing key value layouts change** — if the serialised shape of - `Contract(id)` or `Milestone` changes (e.g. adding a field), the new WASM - must either: - - Add a backward-compatible default for the missing field, or - - Provide an explicit `migrate_storage(target_version)` entrypoint that - re-encodes existing entries. - -3. **Layout version bumps** — the `LayoutVersion` metadata (checked by - `storage_layout_plan()`) must be bumped when value layouts change. The - contract's internal version guard rejects operations if the on-ledger version - is unsupported. - -### 7.3 Current V1 Storage Rules - -Per `docs/escrow/upgradeable-storage.md`: - -- V1 keys and value layouts are **immutable once deployed**. -- Future upgrades must add new version key variants (e.g. `V2(...)`) rather than - mutating V1 key/value formats. -- `LayoutVersion` is checked before all state reads/writes. -- Unknown versions are rejected with `UnsupportedStorageVersion`. -- The `migrate_storage(target_version)` entrypoint is explicit and rejects - unsupported targets. - -### 7.4 Decision Matrix - -| Upgrade Scenario | Migration Step Required? | -|---|---| -| Bug fix in existing logic (no storage changes) | No — plain code swap | -| New read-only query (no new storage keys) | No — plain code swap | -| New mutating entrypoint (no new storage keys) | No — plain code swap | -| New `DataKey` variant for a new feature | Optional — new keys default to empty | -| Changed serialisation of `Contract(id)` | **Yes** — `migrate_storage` required | -| Changed serialisation of `Milestone` | **Yes** — `migrate_storage` required | -| New `LayoutVersion` value | **Yes** — `migrate_storage` required | - ---- - -## 8. Post-Upgrade Monitoring - -After unpausing, monitor the following for at least 24 hours: - -1. **Event stream**: watch for `("emergency", "activated")` events that might - indicate the operator triggered an emergency pause in response to an - unexpected issue. -2. **Contract creation**: verify new `("created", contract_id)` events are - emitted correctly. -3. **Deposits and releases**: verify `("deposited", contract_id)` and - `("mlstn_rls", contract_id)` events are emitted with correct payloads. -4. **Error rates**: monitor for unexpected `ContractNotFound`, - `InvalidState`, or `AccountingInvariantViolated` errors that might indicate - a regression. - ---- - -## 9.

Both flags can never be `true` simultaneously — `release_milestone` + rejects already-refunded milestones and vice versa. +- `work_evidence` is set by the freelancer before the client submits an + approval. It is stored as a `soroban_sdk::String` and length-bounded by + `Error::EvidenceTooLong`. +- `deadline` carries a Unix timestamp in seconds as returned by + `env.ledger().timestamp()`. It is informational: the contract does not + automatically cancel or release on expiry, but a client may request a + timeout refund if the deadline has passed. + +### `MilestoneApprovals` + +Defined in `contracts/escrow/src/types.rs`: + +```rust +#[contracttype] +pub struct MilestoneApprovals { + pub client_approved: bool, + pub freelancer_approved: bool, + pub arbiter_approved: bool, +} +``` + +Each flag is set to `true` by the corresponding party calling +`approve_milestone`.

The Soroban host extends the TTL only when remaining life is strictly + below this value. + +### Write path + +`approve_milestone` in `approvals.rs` writes directly to temporary storage +and sets the TTL in a single pair of calls: + +```rust +env.storage().temporary().set(&approval_key, &approvals); +env.storage().temporary().extend_ttl( + &approval_key, + PENDING_APPROVAL_BUMP_THRESHOLD, + PENDING_APPROVAL_TTL_LEDGERS, +); +``` + +Note: this does **not** use the `ttl::store_with_ttl` helper (which always +sets TTL to the supplied value on every write). Instead it calls `extend_ttl` +directly, which means subsequent calls to `approve_milestone` for the same +(contract, milestone) pair will only extend the TTL when the remaining life +falls below the threshold. + +### Expiry and fail-closed semantics + +Soroban auto-evicts temporary entries once their TTL reaches zero. +`check_approvals` reads the key with `env.storage().temporary().get(…)`, which +returns `None` for both absent and evicted entries.

Unauthorized milestone release + +**Goal:** Release a milestone without the required approval(s). + +**Mitigated by:** + +- `caller.require_auth()` in `release_milestone_impl` — Soroban's native auth + ensures only the holder of the private key for `caller` can sign the + invocation. Passing a forged address fails at the host level. +- Role check against `contract.release_authorization` before any state change + (`UnauthorizedRole` on failure). See + [`docs/escrow/authorization.md`](escrow/authorization.md) for the full + authorization matrix. +- `check_approvals` must return `Ok(true)` before funds move + (`InsufficientApprovals` otherwise). Approvals live in temporary storage; + absent or expired records fail closed. + +**Residual risk:** None within the contract boundary. Token delivery is +handled by the SAC; see the SAC custody section. + +--- + +### 2. Approval replay / stale approval reuse + +**Goal:** Reuse an old approval (e.g., from a previous negotiation round) to +release a milestone without fresh consent. + +**Mitigated by:** + +- Approvals are stored in Soroban **temporary storage** with a TTL of + `PENDING_APPROVAL_TTL_LEDGERS` (120,960 ledgers ≈ 7 days). Expired records + are automatically evicted by the host and treated as absent. +- `clear_approvals` removes the `MilestoneApprovals` entry immediately after a + successful release. A released milestone cannot be approved or released again + (`MilestoneAlreadyReleased`). +- Approvals are scoped to `(contract_id, milestone_index)`. An approval for + milestone 0 cannot satisfy milestone 1. + +**Residual risk:** If the approval window (7 days) is long relative to the +intended review period, a party could grant approval and then change their mind +but be unable to revoke it before the other party calls `release_milestone`. +Approval revocation is not currently implemented; see +[Future Improvements](#future-improvements). + +--- + +### 3. Double release (release the same milestone twice) + +**Goal:** Transfer the milestone amount to the freelancer more than once. + +**Mitigated by:** + +- `milestone.released` flag is checked before any state change + (`MilestoneAlreadyReleased`). +- The flag is written atomically with the `released_amount` increment in the + same `env.storage().persistent().set()` call. +- A finalized contract rejects all further mutations (`AlreadyFinalized`). + +--- + +### 4. Release a refunded milestone + +**Goal:** Extract funds from a milestone already returned to the client. + +**Mitigated by:** + +- `milestone.refunded` flag is checked at the start of + `release_milestone_impl` (`AlreadyRefunded`). + +--- + +### 5. Over-release (extract more than the available balance) + +**Goal:** Release milestones totaling more than the funded balance. + +**Mitigated by:** + +- `available_balance = contract.funded_amount - contract.released_amount - contract.refunded_amount` + is computed and compared to `milestone.amount` before the transfer + (`InsufficientFunds`). +- The accounting invariant + `total_deposited == released_amount + refunded_amount + available_balance` + is enforced on every balance-changing operation. See + [`docs/escrow/balance-conservation-invariant.md`](escrow/balance-conservation-invariant.md). + +--- + +### 6. Milestone amount manipulation at creation + +**Goal:** Create a milestone with a zero, negative, or overflow amount to break +accounting later. + +**Mitigated by:** + +- `amount_validation::validate_milestone_amounts` in `create_contract` enforces: + - Each amount is strictly positive (≥ 1 stroop). + - Each amount does not exceed `MAX_SINGLE_MILESTONE_STROOPS` + (1 × 10¹³ stroops). + - The total of all amounts does not exceed the governed + `max_escrow_total_stroops` cap (falls back to `i128::MAX` when unset). + - Accumulation uses `checked_add`, returning `PotentialOverflow` instead of + panicking. +- Milestone amounts are immutable after `create_contract`; no entrypoint + modifies them. + +--- + +### 7. Index out-of-bounds / invalid milestone index + +**Goal:** Reference a non-existent milestone to trigger a panic or access +unintended state. + +**Mitigated by:** + +- Both `approve_milestone` and `release_milestone_impl` compare + `milestone_index` against `milestones.len()` and panic with + `IndexOutOfBounds` if out of range. + +--- + +### 8. Role confusion (arbiter is client or freelancer) + +**Goal:** Register a participant as their own arbiter to gain elevated release +authority. + +**Mitigated by:** + +- `create_contract` rejects any arbiter address equal to `client` or + `freelancer` with `InvalidArbiter`. +- `ArbiterOnly` and `ClientAndArbiter` modes additionally require `arbiter` to + be `Some(...)` at creation time; `MissingArbiter` is returned otherwise. + +--- + +### 9. MultiSig bypass (release with only one signature) + +**Goal:** In MultiSig mode, trigger release with only client or freelancer +approval. + +**Mitigated by:** + +- `check_approvals` for MultiSig mode requires + `approvals.client_approved && approvals.freelancer_approved` — both flags + must be `true`. +- `approve_milestone` rejects duplicate approvals from the same party + (`AlreadyApproved`), so a single key cannot set both flags. + +--- + +### 10. Duplicate approval from the same party + +**Goal:** Set both the client and freelancer approval flags using the same key +(e.g., by calling `approve_milestone_release` twice with different role claims). + +**Mitigated by:** + +- Approval identity is determined by comparing the `caller` address against + the stored `contract.client`, `contract.freelancer`, and `contract.arbiter` + fields — not by a caller-supplied role parameter. +- `AlreadyApproved` is returned if the same party's flag is already `true`. + +--- + +### 11. Release while paused or in emergency mode + +**Goal:** Push a release through during an incident response window. + +**Mitigated by:** + +- `Self::require_not_paused` is called at the start of + `release_milestone_impl` (and again after TTL extension as defense in + depth). `ContractPaused` or `EmergencyActive` is returned while the flag is + set. + +--- + +### 12. Release on a finalized contract + +**Goal:** Mutate milestone state after the contract has been closed. + +**Mitigated by:** + +- `Self::require_not_finalized` is called at the start of + `release_milestone_impl` and again after TTL extension. `AlreadyFinalized` + is returned if a finalization record exists. + +--- + +### 13. Release on an incorrect contract status + +**Goal:** Release a milestone on a contract that is `Created`, `Cancelled`, +`Completed`, etc. + +**Mitigated by:** + +- `release_milestone_impl` checks `contract.status == ContractStatus::Funded` + and returns `InvalidState` otherwise. + +--- + +### 14. Milestone deadline manipulation + +**Goal:** Manipulate `deadline` or `updated_at` fields to fake schedule +compliance or exploit timeout logic. + +**Context:** Schedule metadata (`due_date`, `title`, `description`) is +informational only; the on-chain contract does not automatically release or +refund based on deadlines. `updated_at` is set from `env.ledger().timestamp()` +by the contract — callers cannot supply it. + +**Mitigated by:** + +- The `deadline` field on `Milestone` is optional and does not gate any + value-moving operation in the current implementation. +- `set_milestone_schedule` is restricted to the client + (`contract.client.require_auth()`) and rejects past `due_date` values + (`ScheduleDueDateInPast`). +- Once a milestone is released, its schedule entry is immutable + (`ScheduleImmutableAfterRelease`). + +**Residual risk:** Deadline enforcement is the responsibility of the calling +application; on-chain, overdue milestones cannot self-trigger a refund without +a client-initiated call. + +--- + +### 15. Work evidence injection + +**Goal:** Supply a crafted `work_evidence` string to trigger unexpected +contract behavior. + +**Mitigated by:** + +- `work_evidence` is a free-form `Option` stored as-is.

Understanding these mechanics is essential for auditors and integrators interacting with the escrow lifecycle. + +## Settlement Data Model + +The escrow contract maintains an internal accounting ledger that tracks the lifecycle of funds for a specific contract. This accounting is entirely on-chain and mirrors the actual token balances held in the Stellar Asset Contract (SAC). + +### Core Accounting Fields +The `Contract` struct tracks three primary cumulative fields: +- **`funded_amount`**: The total amount of tokens (in stroops) that the client has successfully deposited into the escrow via SAC transfers. +- **`released_amount`**: The total amount of tokens (in stroops) that have been released (paid out) to the freelancer. This includes both the freelancer's net payout and the accumulated protocol fees retained by the contract. +- **`refunded_amount`**: The total amount of tokens (in stroops) that have been refunded back to the client. + +### Milestone Tracking +Each `Milestone` struct tracks its own state, which maps to the contract's cumulative fields: +- `amount`: The target funding for this milestone. +- `released`: A boolean flag indicating if the milestone has been paid out. +- `refunded`: A boolean flag indicating if the milestone has been refunded. + +## Core Invariants + +The integrity of the escrow system relies on strict accounting invariants. These are enforced before any state mutation or token transfer occurs. + +### 1. The Refundable Balance Invariant +The `refundable_balance` represents the amount of tokens currently locked in escrow that can still be released or refunded. +```text +refundable_balance = funded_amount - released_amount - refunded_amount +``` + +**Guarantees:** +- **Non-negative**: `refundable_balance >= 0` at all times. The contract can never become insolvent. +- **Additive Decomposition**: At any point in the lifecycle, `funded_amount == released_amount + refunded_amount + refundable_balance`. +- **Terminal Zero**: `refundable_balance` reaches `0` strictly when all milestones are either `released` or `refunded`. + +### 2. Deposit Cap Invariant +A contract can never hold more funds than the sum of its milestones. +```text +funded_amount <= SUM(milestone.amount) +``` +Over-funding is prevented during the deposit preflight check via `checked_add`, panicking with `InvalidDepositAmount` if this limit is breached. + +### 3. Atomic SAC Custody +The contract's accounting fields are never updated unless the underlying SAC `transfer` succeeds. +- During a deposit, the `token::Client::transfer(client, escrow, amount)` is executed before `funded_amount` is increased. +- During a release or refund, the outward transfer is executed before `released_amount` or `refunded_amount` is increased. +If a SAC transfer fails (e.g., insufficient balance or frozen trustline), the transaction reverts, leaving the accounting state untouched. + +## Entrypoints Mutating Settlement State + +Only three entrypoints are authorized to mutate the settlement state. All three are guarded by the emergency circuit breaker (`ContractPaused` / `EmergencyActive`). + +### `deposit_funds` +- **Action**: Pulls tokens from the client to the escrow contract. +- **State Change**: Increases `funded_amount` by the deposited amount. +- **Status Update**: Transitions the contract to `PartiallyFunded` or `Funded` (if `funded_amount == SUM(milestone.amount)`). + +### `release_milestone` +- **Action**: Pushes tokens from the escrow contract to the freelancer (net of the protocol fee) and retains the fee. +- **State Change**: Increases `released_amount` by the milestone's full `amount`. Sets the milestone's `released` flag to `true`. +- **Status Update**: Transitions the contract to `Completed` if all milestones are released. + +### `refund_unreleased_milestones` +- **Action**: Pushes unreleased tokens from the escrow contract back to the client. +- **State Change**: Increases `refunded_amount` by the sum of the refunded milestones. Sets the `refunded` flag to `true` on those milestones. +- **Status Update**: Transitions the contract to `Refunded` if the entire `funded_amount` has been refunded. + +## Worked Example + +Let's trace a 2-milestone contract through a partial release and a refund. + +**1. Creation** +- Milestone 1: 100 USDC +- Milestone 2: 150 USDC +- Total Required: 250 USDC +- **State**: `funded_amount = 0`, `released_amount = 0`, `refunded_amount = 0`. `refundable_balance = 0`. + +**2. Full Deposit** +- The client deposits 250 USDC. +- SAC transfers 250 USDC from Client to Escrow. +- **State**: `funded_amount = 250`, `released_amount = 0`, `refunded_amount = 0`. `refundable_balance = 250`. + +**3. Release Milestone 1** +- The client approves and releases Milestone 1 (100 USDC). +- Assuming a 5% protocol fee (5 USDC). +- SAC transfers 95 USDC from Escrow to Freelancer.

The current implementation uses the `released` and `refunded` booleans inside the milestone vector as the source of truth. + +## 4. Invariants + +The contract logic enforces the following invariants at the storage layer. + +### 4.1 Lifecycle invariants + +- A contract must be initialized before any money-flow entrypoint can run. +- `create_contract` writes a new `Contract` record and its milestone vector atomically with the new contract id. +- A deposit is only accepted for `Created` or `PartiallyFunded` contracts and cannot be used after `Cancelled` or `Refunded`. +- A release can only happen when the contract is in `Funded` state and the target milestone is still unreleased and unrefunded. + +### 4.2 Accounting invariants + +The core invariant is: + +- `available_balance = funded_amount - released_amount - refunded_amount` +- `available_balance >= 0` +- A release or refund must never make that value negative. + +The code checks this before mutating storage in the release and refund paths, and it panics with `AccountingInvariantViolated` when the state would become impossible. + +A second, contract-level guard ensures that a milestone release never exceeds the amount available to cover it: + +- `milestone.amount <= available_balance` + +This is what prevents over-release and keeps the persisted accounting consistent. + +### 4.3 Milestone consistency invariants + +- The milestone vector is the canonical place for milestone release/refund flags. +- The aggregate `released_amount` and `refunded_amount` in the `Contract` record must remain consistent with the milestone-level booleans. +- A contract reaches `Completed` only after every milestone is either released or refunded. + +### 4.4 Approval invariants + +Approval records are temporary and fail closed: + +- Missing approvals are treated as insufficient and block release. +- Expired approvals are treated as absent. +- Duplicate approvals from the same participant are rejected. + +### 4.5 Governance and configuration invariants + +- `Admin` is the only address permitted to mutate governance-controlled settings. +- `PendingAdmin` is cleared after acceptance or cancellation of a governance transfer. +- `SettlementToken` is bound once and is not overwritten by later calls. + +## 5. Entrypoints that touch storage + +The following entrypoints are the main storage writers and readers. + +| Entrypoint | Storage touched | Notes | +| --- | --- | --- | +| `initialize` | `Initialized`, `Admin`, `NextContractId`, `ReadinessChecklist` | Bootstraps global state. | +| `create_contract` | `DataKey::Contract(id)`, milestone vector, `NextContractId` | Creates the main contract record. | +| `deposit_funds` | `DataKey::Contract(id)` | Updates funding counters and transitions `Created`/`PartiallyFunded` to `Funded`. | +| `approve_milestone_release` | `DataKey::MilestoneApprovals(contract_id, milestone_index)` | Persists temporary approvals with TTL. | +| `release_milestone` | `DataKey::Contract(id)`, milestone vector, approvals cleanup, `AccumulatedProtocolFees`, pending reputation credits | Mutates lifecycle and accounting state. | +| `refund_*` | `DataKey::Contract(id)`, milestone vector | Updates refund counters and milestone flags. | +| `bind_settlement_token` | `DataKey::SettlementToken` | Binds the SAC token used for custody transfers. | +| `set_protocol_fee_bps` | `DataKey::ProtocolFeeBps` | Updates protocol fee configuration. | +| `propose_governance_admin` / `accept_governance_admin` / `cancel_governance_admin_proposal` | `DataKey::PendingAdmin`, `DataKey::Admin` | Manage two-step admin transfers. | +| `issue_reputation` | `DataKey::ReputationIssued(contract_id)`, `DataKey::Reputation(address)`, `DataKey::ReputationComment(contract_id)`, `DataKey::PendingReputationCredits(address)` | Records feedback and pending credit state. | +| `request_client_migration` / migration helpers | `DataKey::PendingClientMigration(contract_id)` | Stores temporary migration requests. | + +## 6. Worked example + +Consider a simple contract with one milestone worth `1000` stroops. + +1. `create_contract` writes: + - `DataKey::Contract(1)` with `status = Created`, `funded_amount = 0`, `released_amount = 0`, `refunded_amount = 0` + - `(DataKey::Contract(1), "milestones")` with one milestone whose `released` and `refunded` flags are both `false` + - `DataKey::NextContractId = 2` +2. `deposit_funds` updates the contract record so that `funded_amount` becomes `1000` and the status becomes `Funded`. +3. `approve_milestone_release` writes a temporary approval record under `DataKey::MilestoneApprovals(1, 0)`. +4. `release_milestone` reads the same milestone from the vector, flips that milestone’s `released` flag to `true`, increments `released_amount` in the contract record, and clears the approval entry. +5. If the contract is fully released, the contract status changes to `Completed` and the pending reputation credit counter is incremented for the freelancer. + +That flow is the easiest way to see how the storage model behaves in practice: each entrypoint mutates the contract record, the milestone vector, or the temporary approval record, but the invariants remain the same across all paths. + +## 7. Notes for auditors and reviewers + +- The storage model is intentionally split between persistent and temporary state, and the TTL policy is part of the safety story. +- The milestone vector is the canonical source of milestone-level release/refund state. +- The relevant tests live in [contracts/escrow/src/test/storage.rs](../contracts/escrow/src/test/storage.rs) and [contracts/escrow/src/test/accounting_invariants.rs](../contracts/escrow/src/test/accounting_invariants.rs). +- When reading the contract, start with the contract record and the milestone vector; the rest of the storage keys are either configuration, governance, or auxiliary state. diff --git a/error.json b/error.json index aeabb1aa..e69de29b 100644 Binary files a/error.json and b/error.json differ diff --git a/errors.txt b/errors.txt deleted file mode 100644 index a209a182..00000000 --- a/errors.txt +++ /dev/null @@ -1,4231 +0,0 @@ -error[E0428]: the name `amount_validation` is defined multiple times -
