-# Escrow Acceptance Hardening
+# Escrow & Token Transfer Error Handling
 
 ## Overview
 
-The escrow funding flow now enforces a single set of preconditions before a bid can be accepted.
-This applies to both public acceptance entrypoints:
+The escrow module manages the full lifecycle of investor funds: locking them on
+bid acceptance, releasing them to the business on settlement, and refunding them
+to the investor on cancellation or dispute.
 
-- `accept_bid`
-- `accept_bid_and_fund`
+All token movements go through `payments::transfer_funds`, which surfaces
+Stellar token failures as typed `QuickLendXError` variants **before** any state
+is mutated.
 
-## Security Goals
+---
 
-- Ensure the caller is authorizing the exact invoice that will be funded.
-- Ensure only a valid `invoice_id` and `bid_id` pair can progress.
-- Prevent funding when escrow or investment state already exists for the invoice.
-- Reject inconsistent invoice funding metadata before any token transfer occurs.
+## Token Transfer Error Variants
 
-## Acceptance Preconditions
+| Error | Code | When raised |
+|---|---|---|
+| `InvalidAmount` | 1200 | `amount <= 0` passed to `transfer_funds` |
+| `InsufficientFunds` | 1400 | Sender's token balance is below `amount` |
+| `OperationNotAllowed` | 1402 | Investor's allowance to the contract is below `amount` |
+| `TokenTransferFailed` | 2200 | Reserved for future use if the token contract panics |
 
-Before the contract creates escrow, it now checks:
+---
 
-- The invoice exists.
-- The caller is the invoice business owner and passes business KYC state checks.
-- The invoice is still available for funding.
-- The invoice has no stale funding metadata:
-  - `funded_amount == 0`
-  - `funded_at == None`
-  - `investor == None`
-- The invoice does not already have:
-  - an escrow record
-  - an investment record
-- The bid exists.
-- The bid belongs to the provided invoice.
-- The bid is still `Placed`.
-- The bid has not expired.
-- The bid amount is positive.
+## Escrow Creation (`create_escrow` / `accept_bid`)
 
-## Issue Addressed
+### Preconditions checked before any token call
 
-Previously, `accept_bid` reloaded the invoice ID from the bid after authorizing against the caller-supplied invoice. That allowed a mismatched invoice/bid pair to drift into the funding path and risk:
+1. `amount > 0` — `InvalidAmount` otherwise.
+2. No existing escrow for the invoice — `InvoiceAlreadyFunded` otherwise.
+3. Investor balance ≥ `amount` — `InsufficientFunds` otherwise.
+4. Investor allowance to contract ≥ `amount` — `OperationNotAllowed` otherwise.
 
-- escrow being created under the wrong invoice key
-- status index corruption
-- unauthorized cross-invoice funding side effects
+### Atomicity guarantee
 
-Both acceptance paths now share the same validator in [`escrow.rs`](/Users/mac/Documents/github/wave/quicklendx-protocol/quicklendx-contracts/src/escrow.rs).
+The escrow record is written to storage **only after** `token.transfer_from`
+returns successfully. If the token call fails, no escrow record is created and
+the invoice/bid states are left unchanged. The operation is safe to retry.
 
-## Tests Added
+### Failure scenarios
 
-The escrow hardening is covered with targeted regression tests in:
+| Scenario | Error returned | State after failure |
+|---|---|---|
+| Investor has zero balance | `InsufficientFunds` | Invoice: `Verified`, Bid: `Placed`, no escrow |
+| Investor has zero allowance | `OperationNotAllowed` | Invoice: `Verified`, Bid: `Placed`, no escrow |
+| Investor has partial allowance | `OperationNotAllowed` | Invoice: `Verified`, Bid: `Placed`, no escrow |
+| Escrow already exists for invoice | `InvoiceAlreadyFunded` | No change |
 
-- [`test_escrow.rs`](/Users/mac/Documents/github/wave/quicklendx-protocol/quicklendx-contracts/src/test_escrow.rs)
-- [`test_bid.rs`](/Users/mac/Documents/github/wave/quicklendx-protocol/quicklendx-contracts/src/test_bid.rs)
+---
 
-New scenarios include:
+## Escrow Release (`release_escrow`)
 
-- rejecting mismatched invoice/bid pairs with no balance or status side effects
-- rejecting acceptance when escrow already exists for the invoice
+Transfers funds from the contract to the business.
 
-## Security Notes
+### Preconditions
 
-- Validation runs before any funds are transferred into escrow.
-- Existing escrow or investment state is treated as a hard stop to preserve one-to-one funding invariants.
-- The contract still relies on the payment reentrancy guard in [`lib.rs`](/Users/mac/Documents/github/wave/quicklendx-protocol/quicklendx-contracts/src/lib.rs).
+1. Escrow record exists — `StorageKeyNotFound` otherwise.
+2. Escrow status is `Held` — `InvalidStatus` otherwise (idempotency guard).
+3. Contract balance ≥ escrow amount — `InsufficientFunds` otherwise.
+
+### Atomicity guarantee
+
+The escrow status is updated to `Released` **only after** `token.transfer`
+returns successfully. If the transfer fails, the status remains `Held` and the
+release can be safely retried.
+
+---
+
+## Escrow Refund (`refund_escrow` / `refund_escrow_funds`)
+
+Transfers funds from the contract back to the investor.
+
+### Preconditions
+
+1. Escrow record exists — `StorageKeyNotFound` otherwise.
+2. Escrow status is `Held` — `InvalidStatus` otherwise.
+3. Contract balance ≥ escrow amount — `InsufficientFunds` otherwise.
+
+### Atomicity guarantee
+
+The escrow status is updated to `Refunded` **only after** `token.transfer`
+returns successfully. If the transfer fails, the status remains `Held` and the
+refund can be safely retried.
+
+### Authorization
+
+Only the contract admin or the invoice's business owner may call
+`refund_escrow_funds`. Unauthorized callers receive `Unauthorized`.
+
+---
+
+## Security Assumptions
+
+- **No partial transfers.** Balance and allowance are validated before the token
+  call. The token contract is never invoked when these checks fail.
+- **Idempotency.** Once an escrow transitions to `Released` or `Refunded`, all
+  further release/refund attempts return `InvalidStatus` without moving funds.
+- **One escrow per invoice.** A second `create_escrow` call for the same invoice
+  returns `InvoiceAlreadyFunded` before any token interaction.
+- **Reentrancy protection.** All public entry points that touch escrow are
+  wrapped with the reentrancy guard in `lib.rs` (`OperationNotAllowed` on
+  re-entry).
+
+---

+Token transfer failure behavior is covered in:
+
+- [`src/test_escrow.rs`](../../src/test_escrow.rs) — creation failures:
+  - `test_accept_bid_fails_when_investor_has_zero_balance`
+  - `test_accept_bid_fails_when_investor_has_zero_allowance`
+  - `test_accept_bid_fails_when_investor_has_partial_allowance`
+  - `test_accept_bid_succeeds_after_topping_up_balance`
+- [`src/test_refund.rs`](../../src/test_refund.rs) — refund failures:
+  - `test_refund_fails_when_contract_has_insufficient_balance`
+  - `test_refund_succeeds_after_balance_restored`
+
+Existing acceptance-hardening tests (state invariants, double-accept, mismatched
+invoice/bid pairs) remain in the same files.
