Enhance execute_detokenization() to fully eliminate tokens from circulation and clear all tokenization records: - Remove all token holder balances - Clear token locks for all holders - Remove unclaimed dividends - Delete token holders list - Remove transfer restrictions and whitelist - Clear token metadata - Remove TokenizedAsset record (eliminates all tokens) - Clear voting records before removal Add comprehensive tests: - test_token_elimination_on_execution: Verifies complete token removal - test_cannot_propose_after_execution: Ensures no re-proposals after execution Fixes DistinctCodes#473 Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Complete implementation of on-chain insurance policy management for tokenized assets: Policy Management Functions: - create_policy(): Create policies with date validation and asset indexing - cancel_policy(): Cancel policy (holder or insurer authorized) - suspend_policy(): Suspend policy (insurer only) - expire_policy(): Expire policy (permissionless, requires end_date passed) - renew_policy(): Renew policy (insurer only) - get_policy(): Retrieve individual policy details - get_asset_policies(): Get all policies for an asset Data Structure: - InsurancePolicy with policy_type (Liability, Property, Comprehensive, Custom) - PolicyStatus: Active, Suspended, Expired, Cancelled - Coverage amount, deductible, premium tracking - Start/end timestamps with validation - Auto-renewal flag and last payment tracking Features: - Date validation (start_date < end_date, not in past) - Status transition validation (valid state transitions only) - Asset index maintains all policy IDs per asset - Authorization checks (holder/insurer for cancel, insurer for suspend/renew) - Permissionless expiration when end_date passes Comprehensive test suite (14 tests): - Policy creation with validation - Cancellation by holder and insurer - Suspension (authorized and unauthorized) - Expiration (before and after end_date) - Renewal of active and expired policies - Asset policy index - Status transition validation All 55 contract tests passing.
