+//! Bounty escrow contract with explicit, test-backed batch failure semantics.
+//!
+//! ## Batch operation semantics
+//!
+//! `batch_lock_funds` and `batch_release_funds` are strictly atomic
+//! (all-or-nothing): every item is validated before any escrow write or token
+//! transfer occurs. If any row fails validation, the call aborts and sibling
+//! rows remain unchanged. This guarantees no partial commit and no sibling-row
+//! corruption during mixed-success input batches.

 //! # Bounty Escrow Deadline Variant Tests
 //!
-//! Closes #763
-//!
-//! This module validates the three deadline configurations supported by the
-//! bounty escrow contract and documents the time semantics used with the
-//! Soroban ledger timestamp.
-//!
-//! ## Deadline Variants
-//!
-//! | Variant          | Value          | Refund Behavior                                |
-//! |------------------|----------------|------------------------------------------------|
-//! | Zero deadline    | `0`            | Immediately refundable (no waiting period)     |
-//! | Future deadline  | `now + n`      | Blocked until `ledger_timestamp >= deadline`   |
-//! | No deadline      | `u64::MAX`     | Permanently blocked without admin approval     |
-//!
-//! ## Time Semantics
-//!
-//! All deadline comparisons use the **Soroban ledger timestamp** (`env.ledger().timestamp()`),
-//! which represents the close time of the current ledger in **Unix epoch seconds** (u64).
-//!
-//! - The refund check is: `ledger_timestamp >= deadline` → eligible for refund.
-//! - When `deadline == 0`, the condition `now >= 0` is always true for u64, so
-//!   refunds are allowed immediately.
-//! - When `deadline == u64::MAX`, the condition `now >= u64::MAX` is never true
-//!   under normal operation (even 100+ years from epoch), so refunds are
-//!   permanently blocked unless an admin approval overrides the check.
-//! - `release_funds` is **not gated by deadline** — releases can happen at any time
-//!   regardless of the deadline value.
-//!
-//! ## Security Notes
-//!
-//! - Deadline values are stored as-is and never normalized, ensuring the depositor's
-//!   intent is faithfully preserved.
-//! - The `u64::MAX` sentinel is safe because the Soroban ledger timestamp will not
-//!   reach this value within any practical timeframe.
-//! - Admin-approved refunds bypass the deadline check entirely, providing an escape
-//!   hatch for all deadline configurations.
-//! - Partial refunds via `approve_refund` with `RefundMode::Partial` correctly
-//!   preserve the remaining balance and transition to `PartiallyRefunded` status.
+//! This module validates deadline semantics using Soroban ledger timestamps.
