+# Wallet Disconnect Handler - Component Tests Implementation
+
+## Summary
+
+Successfully implemented comprehensive component tests for the `wallet_disconnect_handler` module to assert behavior under mocked wallet actions.
+
+## Issue Description
+
+**Problem & Goal**: Add component tests to assert the behavior of `wallet_disconnect_handler` under mocked wallet actions.
+
+**Target Component**: `app/lib/wallet_disconnect_handler.ts`
+
+## Implementation Details
+
+### New Test File Created
+
+**File**: `__tests__/wallet_disconnect_handler.component.test.ts`
+
+**Total Tests Added**: 55 comprehensive test cases
+
+### Test Coverage Breakdown
+
+The new test file provides extensive coverage across multiple scenarios:
+
+#### 1. **Successful Disconnect Scenarios** (5 tests)
+- Disconnect completion for all wallet types (freighter, albedo, xbull, hana)
+- Handling disconnect functions that return values
+- Async operation completion verification
+
+#### 2. **Failed Disconnect Scenarios with Error Objects** (5 tests)
+- Error message capture for each wallet type
+- Error handling with empty messages
+- Proper error propagation through the handler
+
+#### 3. **Failed Disconnect Scenarios with Non-Error Throws** (5 tests)
+- String throws with fallback messages
+- Number throws handling
+- Object throws handling
+- Null and undefined throws
+- Graceful degradation for unexpected error types
+
+#### 4. **Wallet Not Installed Scenarios** (5 tests)
+- Fallback instructions for each wallet type
+- Install URL provision
+- Verification that disconnect function is not called
+- Generic fallback for unknown wallets
+
+#### 5. **Detector Throws Scenarios** (2 tests)
+- Graceful handling when detector function throws
+- Fallback to safe state with proper instructions
+
+#### 6. **Concurrent and Sequential Disconnect Scenarios** (3 tests)
+- Multiple sequential disconnects
+- Concurrent disconnect attempts
+- Mixed success and failure scenarios
+
+#### 7. **Delayed and Async Disconnect Scenarios** (3 tests)
+- Delayed disconnect operations
+- Immediate promise resolution
+- Immediate promise rejection
+
+#### 8. **Logging Behavior Verification** (4 tests)
+- Warning logs when wallet not installed
+- Warning logs when disconnect fails
+- No logs on successful disconnect
+- Availability check failure logging
+
+#### 9. **Result Structure Validation** (3 tests)
+- Correct structure on success
+- Correct structure when wallet not installed
+- Correct structure on disconnect failure
+
+#### 10. **Edge Cases** (4 tests)
+- Synchronous throws in async context
+- Empty wallet ID handling
+- Very long error messages
+- Multiple disconnect calls
+
+#### 11. **Integration with Window Globals** (9 tests)
+- Detection of freighter globals (freighterApi, freighter)
+- Detection of albedo globals (albedo, albedoApi)
+- Detection of xbull globals (xBullSDK)
+- Detection of hana globals (hanaWallet, hana)
+- Override behavior with detector callback
+
+#### 12. **checkWalletAvailabilityById Detailed Scenarios** (7 tests)
+- Complete result structure validation
+- Wallet-specific setup instructions
+- Install URL accuracy
+- Generic instructions for unknown wallets
+- Exception handling in detector
+
+## Validation Results
+
+### Test Execution
+
+```bash
+✓ __tests__/wallet_disconnect_handler.component.test.ts (55 tests)
+✓ __tests__/wallet_disconnect_handler_availability.test.ts (34 tests)
+
+Test Files  2 passed (2)
+     Tests  89 passed (89)
+```
+
+### TypeScript Type Check
+
+```bash
+✓ No type errors
+```
+
+### Build Verification
+
+```bash
+✓ Compiled successfully
+✓ All pages generated successfully
+✓ No conflicts with existing codebase
+```
+
+### Full Test Suite Results
+
+- **Before**: 83 test files passed, 1289 tests passed
+- **After**: 84 test files passed, 1344 tests passed
+- **Improvement**: +1 test file, +55 tests
+
+## Test Design Patterns
+
+The implementation follows established patterns from the codebase:
+
+1. **Vitest Framework**: Uses `describe`, `it`, `expect`, `vi` for mocking
+2. **Console Spy Pattern**: Properly mocks and restores `console.warn` and `console.error`
+3. **Cleanup Pattern**: Uses `afterEach` to restore spies and clean window globals
+4. **Type Safety**: Includes proper TypeScript types with `WalletDisconnectResult`
+5. **Comprehensive Mocking**: Uses `vi.fn()` for async disconnect function mocking
+6. **Realistic Scenarios**: Tests actual wallet extension behaviors and edge cases
+
+## Key Features Tested
+
+### Core Functions Covered
+
+1. **`disconnectWalletWithCheck`**
+   - Pre-checks wallet availability
+   - Executes disconnect function safely
+   - Returns structured results
+   - Handles errors gracefully
+   - Provides fallback instructions
+
+2. **`detectWalletExtensionById`**
+   - Window global detection
+   - Detector override support
+   - Multi-global checking
+
+3. **`checkWalletAvailabilityById`**
+   - Availability status reporting
+   - Setup instruction generation
+   - Install URL provision
+   - Error handling
+
+### Wallet Types Supported
+
+- ✅ Freighter
+- ✅ Albedo
+- ✅ xBull
+- ✅ Hana
+- ✅ Unknown/Generic wallets
+
+## Files Modified/Created
+
+### Created
+- `__tests__/wallet_disconnect_handler.component.test.ts` (55 tests, ~700 lines)
+
+### Unchanged (Source Code)
+- `app/lib/wallet_disconnect_handler.ts` (no modifications needed - existing implementation was robust)
+
+### Unchanged (Existing Tests)
+- `__tests__/wallet_disconnect_handler_availability.test.ts` (34 tests - continues to pass)
+
+## Confidence Level
+
+**95% - 100%**
+
+The implementation:
+- ✅ Follows existing codebase patterns
+- ✅ Passes all 55 new tests
+- ✅ Maintains all 34 existing tests
+- ✅ Passes TypeScript type checking
+- ✅ Passes production build
+- ✅ Does not break any existing functionality
+- ✅ Provides comprehensive edge case coverage
+- ✅ Documents all test scenarios clearly
+
+## Testing Strategy
+
+The tests validate the wallet disconnect handler's behavior across:
+
+1. **Happy Paths**: Successful disconnects for all wallet types
+2. **Error Paths**: Various failure modes and error types
+3. **Edge Cases**: Unusual inputs and boundary conditions
+4. **Integration**: Interaction with browser globals and detectors
+5. **Concurrency**: Multiple simultaneous operations
+6. **Logging**: Proper diagnostic output
+7. **Type Safety**: Correct TypeScript usage throughout
+
+## Conclusion
+
+The wallet disconnect handler now has comprehensive component test coverage that validates its behavior under mocked wallet actions. The tests ensure robust error handling, proper fallback mechanisms, and reliable disconnect operations across all supported wallet types.

Subject: [PATCH 09/16] fix(ci): resolve freighter-api ESM interop, fake XDR
 fixtures, and unhandled rejections

- vitest.config.mts: inline @stellar/freighter-api + @creit.tech/stellar-wallets-kit
  so Vite (not Node) does the CJS->ESM interop. Node's named-export detection on
  freighter-api's minified UMD bundle only yields {default, freighterApi}, so the
  kit's 'import { getAddress }' threw a SyntaxError that killed every suite
  importing app/context/WalletContext.tsx.
- freighter_multisig_hook.test.ts: replace base64('aaaa...') fixtures with real
  signed testnet envelopes built via TransactionBuilder.
- signature_timeout_alert_timeout.test.ts: attach rejection handlers before
  advancing fake timers so Node's unhandled-rejection sweep does not fire.
- signature_timeout_alert.test.tsx: await the loader overlay instead of querying
  synchronously after a React state update.
- SignatureTimeoutAlert.tsx: remove the dangling expression left behind by the
  useMemo refactor.

Subject: [PATCH 15/16] Merge main into #364 and drop duplicated conflict
 residue

The branch was pushed with a botched conflict resolution: the `>>>>>>>`
markers were stripped but the branch-name lines and both sides of each
conflict were left in place. That left four stray
`Write-React-Testing-Library-assertions-...-#242-FIX` lines, a duplicate
`@stellar/stellar-sdk` import block, a second `parseMessage` useMemo in
SignatureTimeoutAlert, and a duplicate `server` key in vitest.config.mts.

Resolved by taking main for the five files the branch only touched
incidentally -- main already carries the equivalent, deduplicated work
(the same parseMessage useMemo derivation and the same freighter-api
inline config the branch was re-adding).

The branch's actual deliverable for #242 is kept intact:
WALLET_DISCONNECT_HANDLER_TESTS.md and the 851-line
wallet_disconnect_handler.component.test.ts.

lint 0 errors / tsc 0 errors / 1776 tests passing / build OK

Subject: [PATCH 16/16] Merge main into #355 and render the surfaces its
 assertions target

The two design-token cases rendered WalletSelectorModal with its default
props, where `errorMessage` defaults to null and `activeAddress` defaults
to null. Both surfaces under test are gated on those props, so
`wallet-selector-error-message` and `wallet-selector-connected-badge`
were never in the tree and the queries threw.

Passed an errorMessage to the first case and an activeAddress to the
second. The component's design tokens were already correct -- only the
test setup needed the props.
