 ## [Unreleased]
 
 ### Fixed
+
 - `update_campaign_description` now blocks edits once `amount_raised > 0`, preventing bait-and-switch after contributions (#166).
 - `claim_creator_revenue` returns `ValidationFailed` when `revenue_share_percentage > 10000` instead of producing negative math or panicking (#167).
+- `init` and `update_platform_fee` now reject `platform_fee` values above `1000` with `InvalidPlatformFee` instead of silently capping them.
 - `initiate_campaign_transfer` now rejects cancelled or withdrawn campaigns, keeping ownership transfers off terminal campaigns (#323).
 - `resume_campaign` now returns `ValidationFailed` when no pause is active, preventing spurious state writes and `campaign_resumed` events (#348).
 - `update_campaign` now emits both the updated title and description in `campaign_updated`, allowing full metadata indexing without extra reads (#349).
 
 ### Refactored
+
 - Extracted `assert_admin(env, caller)` helper; used in `pause`, `unpause`, and `set_voting_params` to provide a single source of truth for admin authorization (#224).
 
 ### Documentation
+
 - Added `CHANGELOG.md` and documented the Keep-a-Changelog convention in `CONTRIBUTING.md` (#227).

 - Contributions are blocked until verified: `contribute` returns `CampaignNotVerified` while `is_verified = false`.
 - Creator can still update/cancel while active (subject to each method's rules).
 - Full `update_campaign` edits are only available before verification and before any contributions.

 - When `amount_raised >= funding_goal`, the campaign is considered funded.
 - The contract does not set a dedicated boolean for "funded"; it is checked when withdrawing.
 - The creator may call `withdraw_funds` once funded (and if not cancelled / not previously withdrawn).

 ### 5) Cancelled
+
 - Reached by `cancel_campaign` (creator only):
   - sets `is_cancelled = true`
   - sets `is_active = false`
 - Contributors can claim refunds via `claim_refund` after cancellation (if they contributed).
 - Successful refunds remove the contributor's stored contribution record instead of leaving a zero-value entry behind.
+- Refunds also reduce the campaign's live contribution denominator used for revenue sharing, ensuring remaining contributors receive the correct pro-rata share of future revenue claims.
 
 ### 6) Expired / Failed (derived)
+
 - If the deadline passes and the campaign did not reach its goal (`Expired/Failed` derived condition), contributors can claim refunds via `claim_refund`.
 - The contract does not currently toggle `is_active` automatically when a deadline passes; "expired" is computed at call time using the ledger timestamp.

+#162 [BUG] admin_verify and verify_with_votes do not check is_active or is_cancelled
+Repo Avatar
+Iris-IV/ProofOfHeart-stellar
+Summary
+voting::admin_verify and voting::verify_with_votes flip is_verified=true regardless of the campaign's active/cancel state. A cancelled campaign can be marked verified — confusing for indexers and front-end consumers.
+
+Where
+src/voting.rs admin_verify (line ~100)
+src/voting.rs verify_with_votes (line ~125)
+Fix
+Before flipping the bit, return Error::CampaignNotActive if is_cancelled || !is_active.
+
+Acceptance criteria
+ Negative tests covering both functions on a cancelled campaign.
+ No state regression on the happy path.
