From f0448803bb22a2f84d345c26c18a9a508d6a2b72 Mon Sep 17 00:00:00 2001 From: OsagieCynthia Date: Tue, 30 Jun 2026 04:01:16 +0100 Subject: [PATCH 1/6] test(#795): exercise calculate_claimable underflow guard (withdrawn > deposited -> 0) Fix the guard itself: checked_sub().unwrap_or_default() only catches i128 boundary overflow, not an ordinary negative result. Replace with saturating_sub().max(0) so any withdrawn_amount > deposited_amount correctly yields 0 without panicking. Add test_calculate_claimable_underflow_returns_zero that forces the condition via env.as_contract storage manipulation and asserts 0.
