3-4: ⚠️ Potential issue

Consider externalizing credentials.

Having hardcoded credentials in configuration files is a security risk. Consider:

  1. Using environment variables
  2. Using a secure credential store
  3. At minimum, changing from the default password

6-7: 💡 Codebase verification

⚠️ Potential issue

Security concern confirmed: ZMQ endpoints exposed on all network interfaces

The verification confirms that both mainnet and testnet configurations bind ZMQ endpoints to 0.0.0.0, exposing them to all network interfaces. This is particularly concerning because:

  • Mainnet uses port 23708 for both txlocksig and chainlock endpoints
  • Testnet uses port 23709 for both txlocksig and chainlock endpoints
  • No other configuration files show more restrictive ZMQ bindings
  • While RPC is properly restricted to 127.0.0.1/32, ZMQ endpoints remain openly accessible

Recommendations remain valid:

  • Bind to 127.0.0.1 for local-only access
  • Use specific IP for controlled remote access
  • Implement network-level security controls
🔗 Analysis chain

Review ZMQ endpoint security configuration.

Binding to 0.0.0.0 exposes the ZMQ endpoints to all network interfaces, which could pose a security risk. Consider:

  1. Binding to localhost (127.0.0.1) if only local connections are needed
  2. Using a specific IP address if remote access is required
  3. Implementing proper firewall rules
🏁 Scripts executed

19-31: 🛠️ Refactor suggestion

Improve error handling and remove unnecessary clone.

  1. The error message could be more descriptive
  2. The clone() at line 21 seems unnecessary as we're only reading the identity

Apply these improvements:

         let remaining_balance = qualified_identity
-            .identity
-            .clone()
+            .identity
             .transfer_credits(
                 &self.sdk,
                 to_identifier,
                 credits,
                 id.and_then(|key_id| qualified_identity.identity.get_public_key_by_id(key_id)),
                 qualified_identity.clone(),
                 None,
             )
             .await
-            .map_err(|e| format!("Withdrawal error: {}", e))?;
+            .map_err(|e| format!("Failed to transfer {} credits to identity {}: {}", 
+                credits, to_identifier, e))?;

32-38: 💡 Codebase verification

Based on the search results, I can now provide a final response:

Race condition concern is valid - synchronization is needed for concurrent transfers

The code analysis reveals:

  • The transfer operation is async (pub(super) async fn transfer_to_identity)
  • The identity state is shared across multiple async tasks (withdrawals, transfers, etc.)
  • The wallet is protected by Arc<RwLock<Wallet>> but the identity balance updates lack similar synchronization
  • Multiple concurrent tasks can modify the same identity's balance through set_balance()

Key locations requiring attention:

  • src/backend_task/identity/transfer.rs: Add synchronization around balance updates
  • src/model/qualified_identity.rs: Consider adding a mutex for balance state
🔗 Analysis chain

Consider potential race conditions in state updates.

The local state update happens after the transfer is complete. There could be a race condition if multiple transfers are happening concurrently.

Let's check if there are any concurrent access patterns to this method:

Consider implementing optimistic locking or using a mutex to protect the identity state if concurrent transfers are possible.

src/ui/identities/add_new_identity_screen/by_using_unused_balance.rs (2)

43-45: ⚠️ Potential issue

Add proper error handling for amount parsing.

The current implementation silently returns on parse error without providing feedback to the user.

Consider applying this improvement:

-        let Ok(amount_dash) = self.funding_amount.parse::<f64>() else {
-            return action;
-        };
+        let amount_dash = match self.funding_amount.parse::<f64>() {
+            Ok(amount) if amount <= 0.0 => {
+                self.error_message = Some("Amount must be greater than 0".to_string());
+                return action;
+            }
+            Ok(amount) => amount,
+            Err(_) => {
+                self.error_message = Some("Invalid amount format".to_string());
+                return action;
+            }
+        };

8-22: 🛠️ Refactor suggestion

Consider improving error handling and number formatting.

The current implementation has several areas that could be made more robust:

  1. The unwrap() on RwLock could panic if the lock is poisoned
  2. The balance formatting might truncate significant digits
  3. No error handling for max_balance() call

Consider applying these improvements:

 fn show_wallet_balance(&self, ui: &mut egui::Ui) {
     if let Some(selected_wallet) = &self.selected_wallet {
-        let wallet = selected_wallet.read().unwrap(); // Read lock on the wallet
+        let wallet = match selected_wallet.read() {
+            Ok(wallet) => wallet,
+            Err(e) => {
+                ui.label(format!("Error accessing wallet: {}", e));
+                return;
+            }
+        };

-        let total_balance: u64 = wallet.max_balance(); // Sum up all the balances
+        let total_balance: u64 = match wallet.max_balance() {
+            Ok(balance) => balance,
+            Err(e) => {
+                ui.label(format!("Error getting balance: {}", e));
+                return;
+            }
+        };

         let dash_balance = total_balance as f64 * 1e-8; // Convert to DASH units

         ui.horizontal(|ui| {
-            ui.label(format!("Wallet Balance: {:.8} DASH", dash_balance));
+            // Use scientific notation for very small amounts
+            if dash_balance < 0.00000001 {
+                ui.label(format!("Wallet Balance: {:e} DASH", dash_balance));
+            } else {
+                ui.label(format!("Wallet Balance: {:.8} DASH", dash_balance));
+            }
         });
     } else {

src/backend_task/contested_names/query_ending_times.rs (1)

19-20: 💡 Codebase verification

Based on the search results, I can now provide a final response. The codebase shows a clear pattern of error handling through the TaskResult sender channel:

The sender channel should be used to report errors and progress

Looking at similar implementations in the codebase:

  • Other methods use the sender to report errors: sender.send(TaskResult::Error(e))
  • They also use it to report progress: sender.send(TaskResult::Refresh)
  • The method should follow this pattern instead of returning errors directly

Example locations showing this pattern:

  • query_dpns_contested_resources.rs: Uses sender for both errors and refresh notifications
  • refresh_identity.rs: Sends refresh notifications through the channel
  • register_identity.rs: Reports both success and errors through the channel
🔗 Analysis chain

Consider implementing error reporting through the sender channel.

The sender parameter is marked as unused, but given it's a TaskResult channel, it might be intended for error reporting. Consider using it to communicate errors and status updates to the caller, preventing silent failures.

Let's check how other similar methods handle task results:

Consider these improvements:

  1. Use the sender to report errors instead of just returning them
  2. Send progress updates for long-running operations
  3. Report successful completion through the channel

Example usage:

sender.send(TaskResult::Error(format!("error querying vote poll end times: {}", e))).await?;
// or
sender.send(TaskResult::Success(BackendTaskSuccessResult::ContestEndTimeUpdated)).await?;

src/config.rs (2)

63-64: 🛠️ Refactor suggestion

Consider improving error handling for path creation.

While using app_user_data_file_path is a good improvement, the current implementation has two concerns:

  1. Using .expect() could cause runtime panics if path creation fails
  2. The error message "should create .env file path" is not very descriptive

Consider handling the error case explicitly:

-        let env_file_path = app_user_data_file_path(".env").expect("should create .env file path");
-        if let Err(err) = dotenvy::from_path(env_file_path) {
+        let env_file_path = match app_user_data_file_path(".env") {
+            Ok(path) => path,
+            Err(err) => {
+                tracing::error!(?err, "Failed to create .env file path");
+                return Err(ConfigError::LoadError("Failed to create .env file path".into()));
+            }
+        };
+        if let Err(err) = dotenvy::from_path(&env_file_path) {

Committable suggestion skipped: line range outside the PR's diff.


63-64: 💡 Codebase verification

File permissions for .env need to be explicitly managed

The codebase currently lacks explicit file permission management when creating or copying the .env file. While the directory permissions are verified, the sensitive configuration file itself doesn't have controlled permissions:

  • In app_dir.rs, copy_env_file_if_not_exists() uses fs::copy without setting restrictive permissions
  • No file permission controls are implemented after copying the .env file
  • The .env file may contain sensitive data (RPC credentials, wallet keys) but remains with default permissions

Recommendation:

  • Add explicit file permission setting (e.g., 600) after creating or copying the .env file to ensure it's only readable by the owner
🔗 Analysis chain

Verify .env file permissions.

Since the configuration file contains sensitive data (RPC credentials, wallet private keys), ensure that the .env file has appropriate file permissions when created.

The following scripts were executed for the analysis:

src/ui/components/left_panel.rs (1)

40-40: 💡 Codebase verification

Remove unused _app_context parameter

The app_context parameter in add_left_panel function is unused and can be safely removed. The search results show that while AppContext is widely used across other UI components, this particular function doesn't utilize the parameter at all. There are no references to app_context within the function body, and the underscore prefix confirms it's intentionally marked as unused.

  • Remove the _app_context: &Arc<AppContext> parameter from the add_left_panel function signature in src/ui/components/left_panel.rs
🔗 Analysis chain

Verify if _app_context parameter can be removed.

The parameter is marked as unused with an underscore prefix. Consider removing it if it's no longer needed, or document why it's retained for future use.

142-146: 💡 Codebase verification

Based on the gathered information, I can now provide a final response:

Error handling pattern needs correlation across multiple UI components

The investigation reveals this is a systemic pattern across multiple UI components (add_key_screen.rs, add_existing_identity_screen.rs, and register_dpns_name_screen.rs), all sharing the same potential race condition issue with error messages. Each component:

  • Uses a similar status enum pattern with ErrorMessage variant
  • Has identical comments warning about message attribution issues
  • Lacks message correlation with specific operations

Recommendations:

  • Introduce a correlation ID or operation context in the MessageType enum
  • Update all affected components:
    • src/ui/add_key_screen.rs
    • src/ui/identities/add_existing_identity_screen.rs
    • src/ui/identities/register_dpns_name_screen.rs
🔗 Analysis chain

Address potential race condition in error handling.

The comment indicates that error messages could be misattributed if multiple processes are running. Consider:

  1. Adding message correlation IDs to track which operation generated the error
  2. Scoping error handlers to specific operations

Let's check if there are similar patterns in other UI components:


These scripts will help us understand:

  1. How errors are handled across UI components
  2. The structure of the status enum to see available states
  3. The broader message handling context in this specific file

This will help us understand:

  1. The structure of error handling states
  2. Where and how messages are triggered to better assess the race condition concern

Improve max amount calculation implementation.

The current implementation has several concerns:

  1. The magic number 30000 should be defined as a named constant with documentation explaining its purpose
  2. The floating-point conversion factor 1e-8 should be documented
  3. The reason for flooring to 4 decimal places should be explained
  4. There's no validation for negative amounts after subtraction
  5. Floating-point operations might lead to precision loss

+ // Convert satoshis to Dash (1 Dash = 100000000 satoshis)

+ // Maximum decimal places for Dash amounts
+ const MAX_DECIMAL_PLACES: u32 = 4;

+ // Calculate maximum withdrawal amount by reserving transaction fees
+ let reserved_amount = self.max_amount.saturating_sub(TRANSACTION_FEE_RESERVE);
+ if reserved_amount == 0 {
+     self.withdrawal_amount = "0".to_string();
+     return;
+ }
+ let expected_max_amount = reserved_amount as f64 * SATOSHI_TO_DASH;

- // Use flooring and format the result with 4 decimal places

Refactor to handle errors without panicking and improve readability

The function copy_env_file_if_not_exists uses expect, which will cause the program to panic on errors. It's better practice to return a Result and let the caller handle any errors. Additionally, the empty if block at lines 48-49 can be refactored for clarity.

Apply the following changes:

  1. Change the function signature to return a Result:

    -pub fn copy_env_file_if_not_exists() {
    +pub fn copy_env_file_if_not_exists() -> Result<(), std::io::Error> {
  2. Replace expect with the ? operator to propagate errors:

    -let app_data_dir =
    -    app_user_data_dir_path().expect("Failed to determine application data directory");
    +let app_data_dir = app_user_data_dir_path()?;
    
    ...
    
    -fs::copy(&env_example_file_in_exe_dir, env_file_in_app_dir)
    -    .expect("Failed to copy main net env file");
    +fs::copy(&env_example_file_in_exe_dir, &env_file_in_app_dir)?;
    
    ...
    
    -fs::copy(&env_file_in_exe_dir, env_file_in_app_dir)
    -    .expect("Failed to copy main net env file");
    +fs::copy(&env_file_in_exe_dir, &env_file_in_app_dir)?;
  3. Refactor the if condition to avoid the empty block and improve readability:

    -if env_file_in_app_dir.exists() && env_file_in_app_dir.is_file() {
    -} else {
    +if !env_file_in_app_dir.exists() || !env_file_in_app_dir.is_file() {
        // Proceed with copying the file
  4. Ensure the function returns Ok(()) at the end:

    +}
    +Ok(())

The refactored function will handle errors gracefully and enhance code clarity.

Convert refresh_wallet_info to an asynchronous function

The refresh_wallet_info function performs network I/O operations, such as fetching balances from Dash Core and reloading UTXOs, which are potentially blocking. To prevent blocking the thread and improve performance, consider converting this function to async and updating its calls accordingly.


37-38: 🛠️ Refactor suggestion

Avoid holding write locks during potentially blocking operations

Currently, the write lock on the wallet is held while updating the address balance. If update_address_balance involves I/O or other blocking operations, holding the lock can lead to performance issues or deadlocks. Consider minimizing the duration of the lock by preparing data beforehand and acquiring the lock only when necessary for the update.


49-56: 🛠️ Refactor suggestion

Minimize lock duration during UTXO reloading

The write lock on the wallet is held during the call to reload_utxos, which may perform network I/O or intensive computations. Holding the lock for the entire duration can hinder concurrent access. Refactor to release the lock before performing the reload and acquire it only when updating the wallet state with the new UTXOs.


16-16: 🛠️ Refactor suggestion

Avoid converting errors to String; use structured error handling

Converting errors to String with .to_string() and returning Result<_, String> loses valuable context and makes error handling less precise. Implement a custom error type or use an existing error handling crate like thiserror or anyhow to provide richer error information and maintain the error chain.

Handle potential errors in string conversion explicitly

Using unwrap_or_default() in label.to_str().unwrap_or_default() may silently ignore errors during string conversion, potentially leading to empty strings without indication of failure. It's better to handle possible errors explicitly.

Apply this diff to handle the error explicitly:

-        .map(|label| label.to_str().unwrap_or_default());
+        .and_then(|label| label.to_str().ok());

This change ensures that if to_str() fails, it returns None, which will be properly handled in the subsequent logic.

Prevent cross-network updates by including network in the WHERE clause and avoid updating immutable network field

The UPDATE statement in update_local_qualified_identity currently modifies the network field and filters only by id. Identities may exist with the same id across different networks. To prevent unintended updates to identities in other networks, include network in the WHERE clause. Additionally, the network field is typically immutable and should not be updated.

Apply this diff to correct the SQL statement:

 self.execute(
-    "UPDATE identity

Potential infinite loop when waiting for asset lock proof

Similar to the previous issue, the loop at lines 264 to 273 could result in an infinite loop if the asset lock proof never becomes available. Implementing a timeout mechanism here as well would prevent potential hangs in the application.

Apply the same timeout strategy:

use std::time::Instant;

let start_time = Instant::now();
let timeout_duration = Duration::from_secs(60); // Set an appropriate timeout duration

loop {
    {
        let proofs = self.transactions_waiting_for_finality.lock().unwrap();
        if let Some(Some(proof)) = proofs.get(&tx_id) {
            asset_lock_proof = proof.clone();
            break;
        }
    }
    if start_time.elapsed() > timeout_duration {
        return Err("Timed out waiting for asset lock proof".to_string());

Avoid using expect to prevent unintended panics

At line 281, the code uses .expect("expected to create an identifier"). Using expect can cause the application to panic if the function fails. It's safer to handle the error gracefully using ? and propagate it upwards or handle it appropriately.

Modify the code to handle the error:

let identity_id = asset_lock_proof
    .create_identifier()
    .map_err(|e| format!("Failed to create identifier: {}", e))?;

292-292: ⚠️ Potential issue

Avoid using expect to prevent unintended panics

At line 292, using .expect("expected to make identity") can lead to a panic if new_with_id_and_keys fails. It's better to handle the potential error.

Consider Using Password in Seed Generation

The seed is generated using mnemonic.to_seed(""), which means the user's password is not utilized in the seed derivation process. If the intention is to strengthen the seed with the user's password (as per the BIP39 standard), consider passing self.password to to_seed.

Apply this diff if including the password in seed generation is desired:

110-112: ⚠️ Potential issue

Handle potential panics when unwrapping locks

Using .unwrap() on lock acquisitions can cause panics if the lock is poisoned due to a previous thread's panic. To make the application more robust, consider handling PoisonError by providing a fallback or informing the user.

Modify the code to handle potential errors:

 let result = {
-    let mut wallet = wallet.write().unwrap();
+    let mut wallet = match wallet.write() {
+        Ok(guard) => guard,
+        Err(poisoned) => {
+            self.display_message("Failed to acquire wallet write lock", MessageType::Error);
+            return;
+        }
+    };
     wallet.receive_address(self.app_context.network, true, Some(&self.app_context))
 };

By handling the PoisonError, you prevent the application from panicking and provide meaningful feedback to the user.

199-224: ⚠️ Potential issue

Gracefully handle errors when writing to wallet

When updating the wallet alias, unwrapping the write lock can cause a panic if the lock is poisoned. Handle this scenario to maintain application stability.

Modify the code to manage potential errors:

 {
-    let mut wallet = selected_wallet.write().unwrap();
+    let mut wallet = match selected_wallet.write() {
+        Ok(guard) => guard,
+        Err(poisoned) => {
+            self.display_message("Failed to acquire wallet write lock", MessageType::Error);
+            return;
+        }
+    };
     let mut alias = wallet.alias.clone().unwrap_or_default();
     // Rest of the code...
 }

247-296: ⚠️ Potential issue

Handle potential lock poisoning when reading wallet data

In render_address_table, unwrapping the read lock without error handling can lead to panics. To enhance reliability, handle PoisonError when acquiring the read lock.

Modify the code as follows:

 let wallet = match self.selected_wallet.as_ref() {
     Some(selected_wallet) => match selected_wallet.read() {
         Ok(guard) => guard,
         Err(poisoned) => {

     },
     None => {
         self.display_message("No wallet selected", MessageType::Error);
         return action;
     }

Avoid comparing user input to placeholder text

Comparing the user's alias input to the placeholder text can cause unintended behavior if a user sets their alias to the placeholder text (e.g., "An Identity"). This would result in the alias being unset (None). Consider checking only for empty strings to determine if the alias should be left unset.

Improve Error Handling in Balance Check Loop

In the start_balance_check function (lines 175-220), the error handling within the balance checking loop (lines 210-217) logs errors but continues looping indefinitely. This could lead to infinite loops in case of persistent errors. Consider implementing a retry mechanism with a maximum number of retries or exiting the loop upon critical errors to prevent potential resource exhaustion.

* feat: add MCP HTTP server for programmatic access

Embed a streamable-HTTP MCP server (rmcp + axum) that exposes backend
tasks as tools for AI agents. Feature-gated behind `mcp` feature flag
and opt-in via MCP_API_KEY environment variable.

Tools: list_wallets, generate_receive_address, list_core_wallets.
Auth: Bearer token with constant-time comparison (subtle crate).
Supports network switching -- MCP context follows GUI network changes
via ArcSwap.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* feat: support dual MCP transport (stdio + HTTP) with lazy init

Refactor MCP module to support two feature-gated transports:
- mcp-stdio: standalone binary with lazy AppContext initialization
- mcp-http: embedded HTTP server sharing GUI app's context

New binary: dash-evo-tool-mcp (requires mcp-stdio feature).
Neither transport is enabled by default.

* feat: add det-cli MCP client with tool caching and completion

Dynamic CLI client that discovers tools from the MCP server at runtime.
Supports HTTP transport (default) and standalone mode (--standalone).
Caches tool schemas locally for shell completion.

New binary: det-cli (requires `cli` feature).

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* docs: add MCP and CLI quick start guides

Add docs/MCP.md covering the HTTP and stdio transport modes, available tools,
environment variables, and security notes. Add docs/CLI.md covering det-cli
connection modes, subcommands, and shell completion setup. Update README.md
with a Programmatic Access section linking to both guides.

* refactor(cli): read MCP config from app .env file

- Load app's .env on startup so MCP_API_KEY/MCP_LISTEN are available

- Replace DET_CLI_BEARER with MCP_API_KEY (matches server config)
- Derive server URL from MCP_LISTEN env var; fall back to 127.0.0.1:9527
- Auto-select stdio mode when no API key is configured; HTTP when set
- Make subcommand optional: bare `det-cli` lists tools live
- Inject cached tool list into --help output via print_cached_tools_help()
- Update docs/CLI.md to reflect new config and connection behavior

* refactor(cli): implicit versioned cache, remove Cache subcommand

- Remove explicit `det-cli cache` subcommand; tool list is cached
  automatically after every `tools` invocation
- Add ToolCache struct with version field; cache includes server version
  from MCP peer info (falls back to PKG_VERSION)
- Cache staleness: --help only shows cached tools when version matches
  the binary; stale cache prompts user to run `det-cli` to refresh
- Add `#[command(version)]` so `det-cli --version` works
- Fix server info access: use `client.peer().peer_info()` (correct rmcp
  API) instead of non-existent `peer_server_info()`
- Update bash completion jq path to `.tools[].name` for new cache format
- Update docs/CLI.md to reflect automatic caching behavior

* fix(cli): show meaningful errors when AppContext init fails

- Add tracing subscriber (stderr, warn level) for non-serve CLI paths
  so tracing::error!() from AppContext::new() is visible to users
- Pre-validate network config exists before attempting AppContext init,
  giving a clear error like "no configuration found for network 'Dash'.
  Check your .env file has MAINNET_dapi_addresses set."
- Fall through message now says "check logs for details" instead of
  the opaque "failed to create AppContext"

* feat(mcp): add network tool, remove --network CLI flag

Replace the --network CLI flag with a proper `network` MCP tool that
returns the active network and available configured networks as JSON.
This keeps det-cli as a thin client with no local logic — network
info comes from the server, same as all other operations.

Changes:
- Add `network` tool to DashMcpService (active + available networks)
- Remove --network flag from det-cli
- Remove network_override threading (ContextProvider::Lazy, new_lazy,
  init_app_context, start_stdio)
- Simplify init_app_context to use DB default only
- Add available_network_names() and network_display_name() helpers
- Make AppContext.network and data_dir pub (needed by MCP tools)
- Update docs/CLI.md and docs/MCP.md

* fix: silently skip unconfigured networks in Config loading

Missing network configs are normal — not every user configures all four
networks. Remove tracing::error! spam and the hard mainnet requirement.
Only fail when no networks are configured at all. The actual network
availability check happens in init_app_context where it matters.

* feat(cli): clean error messages and network tool fixes

- Handle rmcp ServiceError with typed matching instead of string parsing.
  McpError variant extracts message + code directly from ErrorData fields.
- Suppress rmcp service-level tracing warnings (duplicates handled errors)
- Revert network tool to use AppContext (correct for embedded mode —
  needs working config to be useful)
- Make AppContext.network and data_dir pub (needed by MCP tools)
- Add collect_available() helper for listing configured networks

* feat(mcp): start SPV and wait for wallets in standalone mode

In CLI/stdio mode, init_app_context now starts the SPV client after
creating AppContext so wallet operations work. The init returns
immediately — tools like list-wallets and network are not blocked.

The generate-receive-address tool polls ConnectionStatus via
trigger_refresh() until SPV reaches Synced state (60s timeout),
then verifies the specific wallet is loaded into SPV's det_wallets
map before dispatching the backend task.

* feat(cli): add per-tool --help support

Extract SPV wait loop from generate_receive_address into a reusable
wait_for_spv_sync() helper shared by both SPV-dependent tools.

* fix(cli): use wrapper pattern for generate_completion bash output

The generate_completion() function was emitting a standalone _det_cli_tools
function with its own `complete -F` registration, overriding clap's built-in
completions. Now uses the same _det_cli_wrapper pattern as install_bash_completion()
— calls clap's _det-cli first, then adds dynamic tool/parameter names.

without waiting for SPV to finish syncing. Now waits for green state like
the other wallet-dependent tools.

* refactor(cli): split det_cli into modules and add headless feature

Split the 546-line single-file binary into a multi-file directory:
main.rs, connect.rs, cache.rs, completion.rs, help.rs.

Add `headless` feature flag (= ["cli", "mcp"]) and `det-cli headless`
command that runs as a standalone HTTP MCP server daemon with bearer
auth, ctrl+c graceful shutdown, and eager AppContext initialization.

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* refactor(mcp): migrate tools from proc-macro to trait-based ToolBase/AsyncTool pattern

Replace #[tool_router]/#[tool] proc-macro approach with rmcp's
ToolBase + AsyncTool traits. Each tool is now a standalone struct
in its own domain file, enabling auto-generated schemas, typed
output with structuredContent, and per-tool annotations.

New files:
- error.rs: McpToolError enum with From<McpToolError> for ErrorData
- resolve.rs: wallet resolution and SPV sync helpers (extracted)
- tools/mod.rs: shared param types (WalletIdParams, EmptyParams, etc.)
- tools/network.rs: NetworkTool, ListWalletsTool
- tools/wallet.rs: GenerateReceiveAddress, WalletBalancesQuery,
  SendCoreFunds, FetchPlatformBalances (new)
- tools/meta.rs: DescribeTool

Also cleans up dispatch.rs (removes resolve_wallet/task_error_to_mcp)
and simplifies server.rs (manual ServerHandler impl).

tools so MCP clients can assert the expected network before executing.
If the caller provides a network name that does not match the server's
active network, the request is rejected with an InvalidParams error.

Tools guarded: generate_receive_address, wallet_balances,
fetch_platform_address_balances, send_core_funds, query_withdrawals,
list_wallets.

Exempt (by design): network (discovery tool), describe_tool (meta).

Replace String-based McpToolError with typed thiserror variants
(WalletNotFound, InvalidParam, NetworkMismatch, SpvSyncFailed,
TaskFailed, Internal) each mapped to a distinct MCP error code.

Add input validation at the MCP layer for SendCoreFunds: reject
zero amounts, validate Dash address prefix format, and require the

cross-network transfers.

Add INTENTIONAL(PROJ-003) annotation for tool_describe naming.

- Enforce minimum 16-character MCP_API_KEY at server startup; refuse
  to start and log error if too short.
- Return JSON body {"error": "unauthorized"} on 401 instead of bare
  status code.
- Log failed auth attempts at warn level with client address (never
  log the attempted key).
- Add ConnectInfo<SocketAddr> extraction for auth logging.
- Document why the dispatch channel receiver is intentionally dropped
  in headless/CLI mode.
- Fix collapsible_if clippy lint in server.rs.

* refactor: pub(crate) AppContext fields, deduplicate bash completion

- Change AppContext.data_dir and .network from pub to pub(crate) and
  add data_dir()/network() accessor methods for external consumers.
- Extract the bash completion wrapper script to a shared constant in
  completion.rs, eliminating duplication between generate and install.
- Document TOCTOU-safe pattern in DashMcpService::ctx() docstring
  (each tool calls ctx() exactly once and passes the Arc snapshot).

* fix(config): log parse failures instead of silently swallowing them

Add tracing::debug! before .ok() when parsing per-network configs
from environment variables, so parse errors are visible in logs
instead of silently falling through to "no config found".

* test(mcp): add unit tests for MCP validation layer

15 tests covering:
- API key length validation (too short rejected, 16+ accepted, empty)
- Amount validation (zero rejected, positive accepted)
- Address format validation (empty, valid mainnet/testnet, invalid prefix)
- McpToolError Display output for all variants
- MCP error code distinctness for custom codes

* docs: headless build note, feature flag deps, MCP user stories

- Add note in MCP.md that headless mode requires building from source.
- Fix CONTRIBUTING.md feature flag table: clarify headless depends on
  cli + mcp rather than claiming all features are independent.
- Add MCP-001 and MCP-002 user stories for CLI wallet management and
  AI agent MCP server access.

* docs: add guide for exposing backend tasks via MCP/CLI

Add docs/EXPOSING_BACKEND_TASKS.md — a concise reference with architecture
rules, step-by-step checklist, and don'ts for adding new MCP tools that
wrap BackendTask variants. Cross-reference from CLAUDE.md and CONTRIBUTING.md.

* fix: address review findings from CodeRabbit and Copilot

- Fix jq query in bash completion: use `input_schema` (snake_case)
  instead of `inputSchema` (camelCase) to match rmcp serialization
- Validate hex seed hash exists in wallet map before accepting it,
  preventing misleading errors for non-existent wallets
- Version-check cache in print_tool_help() to reject stale entries
- Add headless subcommand to custom help output (cfg-gated)
- Return non-zero exit for unknown tool help lookups
- Add Accept: application/json header to MCP curl examples

* fix: address 7 PR review findings for MCP server

- docs/MCP.md: mark `network` as required for `core_funds_send`
- docs/CLI.md: add `network=testnet` to send example, remove misleading
  "optional" example
- src/app.rs: initialize MCP HTTP server with context matching
  `chosen_network` instead of hardcoded mainnet
- src/mcp/tools/wallet.rs: make `SendFundsParams.network` a non-optional
  `String` to match runtime requirement
- docs/EXPOSING_BACKEND_TASKS.md: fix typo `InvalidParams` → `InvalidParam`
- CLAUDE.md: fix same `InvalidParams` → `InvalidParam` typo
- src/mcp/tests.rs: remove env var tests that race with parallel tests
  due to unsynchronized `set_var`/`remove_var`

* fix: address PR #773 review comments across MCP server

Bot issues fixed:
- #35: WalletNotFound stores only the identifier, not full error sentence
- #36: MCP log differentiates unset vs invalid MCP_API_KEY
- #37: Release workflow splits GUI and CLI builds (GUI without --features cli,
  CLI with --features headless --bin det-cli)
- #38: SendCoreFunds validates empty network string before require_network
- #39: Remove unnecessary ensure_spv_synced() from QueryWithdrawals
- #40: Remove input_schema() override from NetworkTool

Human issues addressed:
- #41: Tool table includes det-cli command column
- #42: CLI section added to MCP.md
- #43: Headless mode performance characteristics documented
- #45: Authentication section with setup, behavior, and security guidance
- #46: ListWalletsTool moved from network.rs to wallet.rs
- #47: TODO added for withdrawal pagination (requires backend changes)
- #48: TODO added for structured JSON output (requires new backend variant)
- #49: Verified correct BackendTask dispatch for withdrawals

Issue #44 (CLAUDE.md duplication): no actual duplication found — the MCP
section in CLAUDE.md covers architecture guidance while docs/MCP.md covers
usage. Both serve distinct purposes.
