+/// Integration tests for issue #276.
+///
+/// Extends pause-blocking coverage to the full cross-contract lifecycle.
+///
+/// Three sub-scenarios prove that pausing *any one* of the three deployed
+/// contracts mid-lifecycle produces a clean, well-typed failure rather than a
+/// stuck or inconsistent state across the others:
+///
+///   1. Invoice paused mid-flow  — `mark_paid` blocked; treasury is unaffected
+///   2. Treasury paused mid-flow — `propose_settlement` / `execute_settlement`
+///                                  blocked (panics with "ContractPaused");
+///                                  invoice and compliance are unaffected
+///   3. Compliance paused mid-flow — `allow_address` blocked so the compliance
+///                                    gate always rejects; treasury settlement
+///                                    remains Pending, invoice remains Paid
+///
+/// Each sub-scenario verifies:
+///   * The paused contract returns the correct error (typed or panic message)
+///   * All *other* contracts remain in their last known good state
+///   * After unpause the blocked operation succeeds (recovery path)
+///
+/// ### Notes on treasury error handling
+/// The treasury contract is `#[no_std]` and uses `panic!()` (abort-on-panic)
+/// for error paths.  `try_*` client wrappers cannot catch abort panics, so
+/// treasury pause-rejection is verified via `#[should_panic(expected = …)]`.
+/// Invoice and compliance use `Result`-returning functions and are verified via
+/// `try_*` wrappers as usual.
