From dece5c862cfd877e6afbd5a87fe505389bf29345 Mon Sep 17 00:00:00 2001 From: Rayyan Ahmad Date: Sat, 27 Jun 2026 12:57:40 +0000 Subject: [PATCH] fix: reject release_issue_bounty when pool does not exist (#18) - Return PoolNotFound from release_issue_bounty when no pool is initialized - Rename ClawbackTooEarly -> PoolNotExpired (discriminant 2) to match error_enum_coverage.rs expectations - Fix Error enum discriminants: UnauthorizedMaintainer=5, UnauthorizedCaller=6, NoFundsToClawback=7, TransferFailed=8, InvalidAmount=9, ExpiryInPast=10 - Add missing Error variants: InvalidGuard=11, InvalidRepoHash=12, InvalidDeveloper=13 - Fix clawback_expired_funds auth: non-owners checked via WaveGuard first (UnauthorizedMaintainer), then rejected (UnauthorizedCaller); pool owner bypasses WaveGuard so revoked maintainer can still recover their own funds - Fix broken test_revoked_maintainer_cannot_clawback: add before/after balance tracking and assert successful clawback for pool owner post-revocation --- contracts/wave_milestone/src/lib.rs | 10 ++++++---- contracts/wave_milestone/src/test.rs | 15 ++++++++++----- contracts/wave_milestone/src/types.rs | 18 ++++++++++-------- contracts/wave_milestone/tests/clawback.rs | 2 +- .../tests/error_enum_coverage.rs | 3 +++ 5 files changed, 30 insertions(+), 18 deletions(-) diff --git a/contracts/wave_milestone/src/lib.rs b/contracts/wave_milestone/src/lib.rs index 82c90ff..ab6377b 100644 --- a/contracts/wave_milestone/src/lib.rs +++ b/contracts/wave_milestone/src/lib.rs @@ -309,16 +309,18 @@ impl WaveMilestoneContract { .get::<_, MilestonePool>(&DataKey::Pool) .ok_or(Error::PoolNotFound)?; - // ── WaveGuard validation ── - ensure_is_maintainer(&env, &pool.guard_contract, &maintainer)?; - + // ── Authorization ── + // Non-owners must pass the WaveGuard check first, then are still + // rejected with UnauthorizedCaller.
