Not the GUI. +**Status:** Draft for review. +**Base:** PR #860 @976ad0d4, branch `feat/masternode-cli-withdraw`. + +--- + +## 1. Executive Summary + +**Problem.** A masternode/evonode operator who works headlessly (det-cli / MCP, no +GUI) cannot withdraw their node's accumulated Platform credits today. Two gaps +stand in the way, both already solved in the GUI but absent from the tool layer: + +1. **No headless identity load.** Loading a masternode/evonode identity — fetching + it by ProTxHash and binding its owner/voting/payout private keys — is GUI-only + (`add_existing_identity_screen.rs` → `IdentityTask::LoadIdentity`). The existing + `identity_credits_withdraw` MCP tool resolves the identity from the **local + database** (`resolve::qualified_identity`) and fails with *"Load the identity + first using the identity screen or CLI"* — but no CLI load path exists. The + instruction points at a door that isn't built. + +2. **The withdraw tool is not masternode-aware.** `identity_credits_withdraw` + always requires a destination address and always passes `key_id = None`. A + masternode withdrawal signed with the **OWNER** key must force the destination + to the node's registered payout address; the tool has no concept of key mode. + +**Solution direction.** Two thin MCP tools, mirroring patterns already proven in +the codebase: + +- **(A) `identity_masternode_load`** — load a masternode/evonode identity headlessly + from a ProTxHash plus owner/voting/payout private keys. Mirrors the secret-input + mechanism of `core_wallet_import` (`src/mcp/tools/wallet.rs`) and dispatches the + existing `IdentityTask::LoadIdentity`. + +- **(B) `identity_masternode_credits_withdraw`** — a masternode-aware credit + withdrawal supporting **both** key modes, mirroring the GUI's + `withdraw_screen.rs` rules and dispatching the existing + `IdentityTask::WithdrawFromIdentity`. + +Both are adapters per `docs/MCP_TOOL_DEVELOPMENT.md`: no new business logic, no new +backend tasks. The backend already does everything; we are only opening a headless +door to it. + +**Key actors.** Priya (Power User / masternode operator) and Jordan (Platform +Developer) — both on the headless path. The Everyday User (Alex) stays in the GUI +and is explicitly out of scope. + +**Two product decisions already LOCKED (not open for re-litigation here):** + +- Deliver **both** tools (A load + B withdraw). +- Withdraw supports **both** modes, mirroring the GUI: OWNER key → destination + forced to the registered payout address; payout/TRANSFER key → any Core address. + +--- + +## 2. Stakeholder & Actor Analysis + +### Primary actor — Priya Nakamura (Power User / masternode operator) + +| Field | Value | +|---|---| +| Goal here | Withdraw her node's earned Platform credits to Core, scripted, without opening the desktop GUI. | +| Context | Runs a masternode; comfortable with CLI, holds owner/voting/payout keys; understands the payout-address constraint. | +| Pain today | The only withdrawal path is the GUI. Headless automation (cron, ops scripts) is impossible. | +| Success metric | One scripted load + one scripted withdraw, no GUI, clear JSON result with the txid-equivalent confirmation and fees. | + +### Primary actor — Jordan Kim (Platform Developer) + +| Field | Value | +|---|---| +| Goal here | Spin a test evonode identity into the tool from known testnet keys and exercise the withdraw path during dApp/integration testing. | +| Context | Testnet/Devnet; values speed and directness; reads raw protocol numbers (credits, fees). | +| Pain today | Must hand-drive the GUI to load an evonode identity before any headless work. Breaks automation. | +| Success metric | Load by ProTxHash + keys, then withdraw, entirely from a script; actionable errors with numbers, not raw Rust strings. | + +### Secondary actor — AI agent over MCP + +Calls the same two tools via the MCP HTTP/stdio transport. Needs accurate tool +**annotations** (`destructive`, `idempotent`, `open_world`) to decide confirmation +prompts, and a clean JSON schema. The masternode-load tool handles private keys, so +its annotations and its `Debug` redaction matter for agent safety. + +### Supporting systems + +- **Backend task system** — `IdentityTask::LoadIdentity` and + `IdentityTask::WithdrawFromIdentity` (authoritative enforcement layer). +- **Local DB** — `insert_local_qualified_identity` persists the loaded identity so + the withdraw tool's `resolve::qualified_identity` can find it (this is the seam + that makes A→B compose). +- **SPV / DAPI** — load fetches the identity over DAPI; proof verification needs a + synced SPV chain. +- **`Secret` model type** (`src/model/secret.rs`) — zeroizing, page-locked secret + carrier already used by `IdentityInputToLoad`. + +--- + +## 3. Functional Requirements + +### 3.1 Tool A — `identity_masternode_load` + +**Purpose.** Load a masternode or evonode identity headlessly: fetch it by +ProTxHash over DAPI, verify and bind the supplied private keys, and persist it +locally so subsequent tools (withdraw, refresh, etc.) can resolve it. + +**Mirrors.** Secret input → `core_wallet_import` (`ImportWalletParams`, +hand-written redacting `Debug`, zeroizing buffers). Dispatch → the existing +`IdentityTask::LoadIdentity(IdentityInputToLoad)`. + +#### Inputs + +| Param | Type | Required | Notes | +|---|---|---|---| +| `pro_tx_hash` | `String` | yes | The identity handle. ProTxHash is the masternode/evonode identity ID. Accept hex (the canonical MN encoding) and Base58 — `load_identity` already tries Base58 then Hex (`Identifier::from_string`). | +| `node_type` | `String` enum | yes | `"masternode"` or `"evonode"`. Maps to `IdentityType::Masternode` / `IdentityType::Evonode`. **Never** `User`. | +| `owner_private_key` | `String` (WIF or 64-hex) | conditional | At least one key must be present (see rule FR-A4). Bound as the OWNER key. | +| `voting_private_key` | `String` (WIF or 64-hex) | optional | Bound as the voting key on the associated voter identity (load fetches the voter identity via DAPI when supplied). | +| `payout_private_key` | `String` (WIF or 64-hex) | conditional | At least one key must be present (see FR-A4). Bound as the payout/TRANSFER key. | +| `alias` | `String` | optional | Human-readable name; trimmed, empty → none. Falls back to first DPNS name if any (existing load behavior). | +| `network` | `String` | yes | Required. Destructive-adjacent (writes local DB, fetches network). Use `resolve::require_network`. | + +Key formats follow `verify_key_input` exactly: **64-char hex** or **51/52-char +WIF**; empty string → "not supplied" (`None`); any other length is an error. We do +not re-implement this — the backend `verify_key_input` is the single source of +truth, and it returns typed `TaskError::KeyInputValidationFailed { key_name, detail }`. + +#### Outputs + +```json +{ + "identity_id": "", + "node_type": "masternode" | "evonode", + "alias": "", + "owner_key_loaded": true, + "voting_key_loaded": false, + "payout_key_loaded": true, + "available_withdrawal_keys": ["owner", "transfer"], + "payout_address": "", + "dpns_names": ["alice.dash"] +} +``` + +- `available_withdrawal_keys` is derived from `available_withdrawal_keys()` on the + resulting `QualifiedIdentity` (OWNER + TRANSFER for MN/Evonode). It tells the + caller — human or agent — which `key_mode` values the withdraw tool will accept + for this identity, so the second step is self-describing. +- `payout_address` comes from `masternode_payout_address(network)`. It is the + destination the caller gets when withdrawing with the OWNER key. Surfacing it + here means the operator can verify the payout target *before* moving funds. + +#### Behavioral rules + +- **FR-A1** — `node_type` must be `masternode` or `evonode`. Reject `user` (and any + other value) with `InvalidParam` — this tool is masternode-specific by design; + user identities load via a different (future or existing) path. +- **FR-A2** — Construct `IdentityInputToLoad` with `derive_keys_from_wallets = + false` and `selected_wallet_seed_hash = None`. Headless MN load is key-driven, not + wallet-derived. (`keys_input` stays empty — that vec is the User-type manual-key + path.) +- **FR-A3** — On `LoadedIdentity(qi)`, the backend has already called + `insert_local_qualified_identity`. The identity is now resolvable by + `resolve::qualified_identity` for the withdraw tool. No extra persistence in the + tool. +- **FR-A4** — Require **at least one** of `owner_private_key` / `payout_private_key`. + Loading an MN identity with zero signing keys produces a watch-only record that + can sign nothing — useless for the locked use case (withdraw). Reject with a + message that names the two keys and explains they enable the two withdraw modes. + (`voting_private_key` alone does not enable a withdrawal — it only binds the voter + identity.) +- **FR-A5** — Re-loading the same identity is effectively idempotent: the backend + does INSERT-OR-REPLACE keyed by identity ID. Annotate `idempotent(false)` + conservatively (re-load re-fetches network state and can change bound keys), but + document that re-running is safe and updates the local record. + +### 3.2 Tool B — `identity_masternode_credits_withdraw` + +**Purpose.** Withdraw credits from a loaded masternode/evonode identity to Core, +honoring the two key/destination modes. + +**Mirrors.** Dispatch → `IdentityTask::WithdrawFromIdentity(qi, Option
, +Credits, Option)`. Destination/key rules → `withdraw_screen.rs` +(`render_address_input`, `show_confirmation_popup`). + +#### Inputs + +| Param | Type | Required | Notes | +|---|---|---|---| +| `identity_id` | `String` | yes | Base58 identity ID (the loaded MN identity). Resolved via `resolve::qualified_identity`. | +| `key_mode` | `String` enum | yes | `"owner"` or `"transfer"`. Selects which available withdrawal key signs. Explicit, not inferred — see FR-B1. | +| `to_address` | `String` | conditional | Core address. **Required** for `transfer` mode, **forbidden/ignored** for `owner` mode (destination is forced). See FR-B2/B3. | +| `amount_credits` | `u64` | yes | > 0 (`resolve::validate_credits`). | +| `network` | `String` | yes | Required (destructive). `resolve::require_network`. | + +#### Outputs + +```json +{ + "identity_id": "", + "key_mode": "owner" | "transfer", + "to_address": "", + "amount_credits": 100000, + "estimated_fee": 1234, + "actual_fee": 1230 +} +``` + +`to_address` echoes the address **actually used** — for OWNER mode that is the +resolved payout address, not a caller input. The caller always learns where the +funds went. + +#### Behavioral rules — the two modes (LOCKED) + +- **FR-B1 — Explicit key mode.** The caller chooses `key_mode` explicitly rather + than the tool guessing from key availability. An MN/evonode identity may have both + OWNER and TRANSFER keys loaded; the destination semantics differ sharply between + them (forced vs free), so an ambiguous auto-pick is a foot-gun for a fund-moving + operation. The tool resolves `key_mode` to a concrete `KeyID` by scanning + `available_withdrawal_keys()` for a key whose purpose matches + (`OWNER` ↔ `transfer`→`TRANSFER`). If no matching key is loaded, return + `InvalidParam` naming which key is missing and that it must be supplied at load + time. + +- **FR-B2 — OWNER mode forces destination.** When `key_mode = "owner"`: + - Resolve the destination from `masternode_payout_address(network)`. + - If `to_address` was supplied, **reject** with `InvalidParam`: the OWNER-key + withdrawal can only go to the registered payout address, so a caller-supplied + address is a contradiction to surface, not silently ignore. (The GUI hides the + address field entirely in this mode; headless can't hide a field, so it rejects.) + - If the identity has no payout address, reject with a clear message — there is + nowhere for an OWNER-key withdrawal to go. + - Dispatch with `address = Some(payout_address)`, `key_id = Some(owner_key_id)`. + +- **FR-B3 — TRANSFER mode, free destination.** When `key_mode = "transfer"`: + - `to_address` is **required**; validate format (`resolve::validate_address`) and + network match, exactly as `identity_credits_withdraw` does (parse + `NetworkUnchecked` → `require_network(ctx.network())`). + - Reject Platform (bech32m) addresses — withdrawals settle on Core only. Mirror + the GUI's `is_platform_address_string` guard with a calm message. + - Dispatch with `address = Some(parsed_core_address)`, + `key_id = Some(transfer_key_id)`. + +- **FR-B4 — No developer-mode relaxation in the tool.** The GUI relaxes the + payout-address constraint under developer mode (lets an OWNER-key withdrawal go to + an arbitrary address). The headless tool does **not** expose that relaxation: + there is no UI to signal "I know what I'm doing," and a scripted/agent caller + silently sending an OWNER withdrawal to an arbitrary address is exactly the + mistake this constraint exists to prevent. OWNER mode always forces the payout + address. (Open question OQ-3 confirms.) + +- **FR-B5 — Identity must be loaded first.** If `resolve::qualified_identity` fails, + return its existing message — now accurate, because the door (`identity_masternode_load`) + exists. Consider updating the message to name the new tool. + +### 3.3 Network safety (both tools) + +- Both are stateful/destructive: `network` is **required**, enforced via + `resolve::require_network` (not the optional `verify_network`). A mismatch returns + `NetworkMismatch { expected, actual }`. This is the locked cross-network guard and + matches every other fund-moving tool. + +### 3.4 Composition (A → B), validated + +``` +identity_masternode_load (pro_tx_hash + keys + network) + │ fetch by ProTxHash over DAPI, verify keys, bind, persist + ▼ + LoadedIdentity(qi) → insert_local_qualified_identity (INSERT-OR-REPLACE) + │ + ▼ +identity_masternode_credits_withdraw (identity_id + key_mode + ... ) + │ resolve::qualified_identity finds the persisted record + ▼ + WithdrawFromIdentity(qi, dest, credits, key_id) → CreditWithdrawal ST +``` + +The two tools compose through the **local DB**, exactly as the existing +GUI→withdraw flow does. No shared in-memory state, no ordering coupling beyond +"load before withdraw," which the withdraw tool's error already enforces. + +--- + +## 4. Non-Functional Requirements + +### 4.1 Security of private-key input + +- **NFR-S1 — Redacting `Debug`.** The load tool's params struct carries three + private keys. Mirror `ImportWalletParams`: a **hand-written `Debug`** that prints + each key field as `""`. A derived `Debug` would leak keys into MCP error + `data` payloads and logs (`McpToolError::TaskFailed` serializes `{task_err:?}`). + This is the single most important security requirement in this spec. +- **NFR-S2 — Zeroizing buffers.** Wrap raw key strings in `zeroize::Zeroizing` (or + feed them into `Secret::new`, which page-locks and zeroizes) before handing to + `IdentityInputToLoad`. `IdentityInputToLoad` already takes `Secret`, so the tool's + job is to move the input into `Secret` promptly and not retain a plain `String` + copy. +- **NFR-S3 — Keys never in output or errors.** Output reports only *which* keys + loaded (booleans), never the key material. Validation errors name the key by role + ("Owner", "Payout Address") and the failure kind, never echo the value. This is + already how `TaskError::KeyInputValidationFailed` behaves — preserve it. +- **NFR-S4 — Transport caution.** Over MCP HTTP, keys traverse the request body. The + HTTP transport is bearer-auth'd and loopback by default; document that callers + must not send live mainnet MN keys over a non-loopback MCP HTTP endpoint. (Carried + as a documentation note for `docs/MCP.md`, not enforced in code.) + +### 4.2 Network-match enforcement + +- **NFR-N1** — `require_network` on both tools (FR-3.3). Keys are network-scoped; a + WIF parsed against the wrong network fails in `verify_key_input` anyway, but the + explicit network guard fails *first*, with the clearer cross-network message. + +### 4.3 SPV sync prerequisites + +- **NFR-P1 — Load needs SPV.** `load_identity` calls `Identity::fetch_by_identifier` + (and, with a voting key, fetches the voter identity) over DAPI. Per the SPV-gate + rule in `MCP_TOOL_DEVELOPMENT.md`, DAPI proof verification needs a synced SPV + chain. The load tool **must** call `resolve::ensure_spv_synced` before dispatch. +- **NFR-P2 — Withdraw and the SPV inconsistency (FLAG).** The existing + `identity_credits_withdraw` *intentionally skips* `ensure_spv_synced` (comment: + "no SPV sync needed — this tool only dispatches Platform state transitions"). + This contradicts the documented SPV-gate rule, which says platform-only network + calls still need SPV for proof verification. We have two options: + - **(a)** Match the sibling withdraw tool and skip the gate (consistency with the + one tool a caller will compare against). + - **(b)** Add the gate (consistency with the documented rule and with load). + Recommended: **(b) add the gate** — a withdrawal is the most consequential op in + this spec, and a few seconds of sync-wait is cheap insurance against a proof + failure mid-withdraw. Carried as **OQ-4** for the implementer to confirm and, if + (b), to reconcile the existing tool's comment. Either way, **document the choice**. + +### 4.4 DX / discoverability (per `MCP_TOOL_DEVELOPMENT.md`) + +- **NFR-D1** — Tool names follow `{domain}_{object}_{action}`: + `identity_masternode_load`, `identity_masternode_credits_withdraw`. CLI auto-hyphenates + (`identity-masternode-load`). +- **NFR-D2** — Annotations: + - `identity_masternode_load`: `read_only(false)`, `destructive(false)`, + `idempotent(false)`, `open_world(true)`. + - `identity_masternode_credits_withdraw`: `read_only(false)`, `destructive(true)`, + `idempotent(false)`, `open_world(true)` — identical to `identity_credits_withdraw`. +- **NFR-D3** — Descriptions state the two modes (load: by ProTxHash + keys; + withdraw: owner→payout-forced vs transfer→any-address) and that `network` is + required. Keep them concise — agents read these to choose tools. +- **NFR-D4 — Tools, not CLI code.** Both live in `src/mcp/tools/identity.rs`; + register one line each in `tool_router()`. Zero changes in `src/bin/det_cli/`. + +--- + +## 5. CLI / DX Ergonomics + +### Secret passing — mirror `core_wallet_import` + +`core_wallet_import` takes the mnemonic as a normal string parameter +(`mnemonic: String`) and relies on (1) redacting `Debug` and (2) zeroizing buffers +internally. We follow the **same mechanism** for MN keys — keys are string params, +protected by redacting `Debug` + zeroizing, not by any special channel. This is the +locked, established pattern; introducing a new secret-input channel here would +diverge from the one tool operators already know. + +```bash +# 1.

Confirmed in prior investigation. | + +--- + +## 10. Open Questions & Assumptions + +### Open product questions + +- **OQ-1 — Should `identity_masternode_load` accept ProTxHash in hex only, or also + Base58?** The backend `load_identity` tries Base58 then Hex. ProTxHash is + canonically hex (it is a transaction hash). Recommend: **accept both**, document + hex as the expected form. Low risk; the backend already handles it. +- **OQ-2 — Tool naming: keep `masternode` in the names, or fold into the existing + `identity_credits_withdraw`?** Recommend **separate, masternode-named tools** so + the two modes and the payout-forcing are explicit and discoverable, and so the + existing user-identity withdraw tool stays simple. The alternative — overloading + `identity_credits_withdraw` with a `key_mode` — risks the foot-gun FR-B1 guards + against. **Needs confirmation.** +- **OQ-3 — Confirm OWNER-mode never allows a custom address headlessly (FR-B4).** + The GUI relaxes this in developer mode. We propose **no relaxation** in the tool. + If operators need OWNER→arbitrary-address headlessly, that is a separate, + explicitly-flagged feature. **Needs confirmation.** +- **OQ-4 — SPV gate on the withdraw tool (NFR-P2).** Add it (safety, matches the + documented rule and load) or skip it (match the existing `identity_credits_withdraw`)? + Recommend **add**, and reconcile the sibling tool's comment. **Needs decision.** +- **OQ-5 — `voting_private_key` in scope for v1?** It is part of the GUI three-key + set and binds the voter identity (extra DAPI fetch). It is **not** required for + withdrawal. Recommend: **accept it optionally** for management parity, but it is + cuttable from a minimal first cut if it complicates the load. **Confirm priority.** + +### Assumptions + +- **A-1** The locked scope (both tools, both modes) is final; this spec does not + re-open it. +- **A-2** `IdentityType::Masternode` vs `Evonode` does not change the withdraw + destination rules — both expose OWNER+TRANSFER via `available_withdrawal_keys()` + and both have a `masternode_payout_address`. The `node_type` param only sets the + load type; withdraw behavior is identical across the two. +- **A-3** No new `BackendTask` or `TaskError` variant is needed — both tools are + pure adapters over existing tasks. (If FR-B5's message is reworded to name the new + tool, that is a one-line literal change, not a new variant.) +- **A-4** The headless caller is trusted to hold the MN private keys; this spec does + not add key-custody features beyond the existing zeroizing/redaction guarantees. + +--- + +## Candy Tally (findings surfaced) + +| Severity | Count | Items | +|---|---|---| +| High | 1 | NFR-P2 / OQ-4 — withdraw SPV-gate inconsistency vs the documented rule and the sibling tool. | +| Medium | 3 | FR-A4 (key-less MN load is useless), FR-B1 (auto-pick key_mode foot-gun), FR-B2 (OWNER-mode silent address-ignore vs reject). | +| Low | 2 | FR-B5 message points at a tool that didn't exist (now does), OQ-1 ProTxHash encoding ambiguity. | + +**Total: 6 findings** (1 High, 3 Medium, 2 Low).

The helpers and their sole caller (invoke) are one compile unit, so Task 4 and Task 5 land together to keep the clippy gate green (no transient dead_code).

Each coordinator (`identity-sync`, `platform-address-sync`, `shielded-sync`) runs on a dedicated OS thread that calls `Handle::block_on`. After `sync_now()` completes, the thread is still alive and enters: tokio::select! { _ = tokio::time::sleep(interval) => {} // panics if runtime shutting down _ = cancel.cancelled() => break, } `tokio::select!` polls arms in random order. If `sleep(interval)` is polled before `cancel.cancelled()` (which IS immediately ready) and the Tokio runtime is already shutting down, `Sleep::poll` panics: "A Tokio 1.x context was found, but it is being shutdown." Fix: after `backend.shutdown()` (cancel tokens cancelled, no sync pass in flight), sleep 100 ms inside `block_on` — while the runtime is still alive — to give the OS scheduler time to run the coordinator threads through their `select! → cancel.cancelled() → break` exit path before the runtime tears down. The upstream fix (storing and joining the OS thread's `JoinHandle` in `quiesce()`) would be airtight; this is the correct DET-side mitigation until that lands in `rs-platform-wallet`. The sleep only executes when a wallet backend was actually started; the no-backend early-return path is unchanged.

Root cause recap: each coordinator runs on a dedicated OS thread via `Handle::block_on`. `quiesce()` waits for `is_syncing==false` (persister drain) but does NOT join the thread. The thread is still alive and enters `tokio::select!{ sleep(interval) | cancel.cancelled() }` with random arm ordering. If `sleep` is polled first after the runtime starts tearing down, `Sleep::poll` panics: "A Tokio 1.x context was found, but it is being shutdown." No sleep duration can reliably beat an in-flight DAPI retry. Deterministic fix: `std::process::exit` after flushing stdout/stderr, applied at all three CLI exit points: - `run_stdio_server()` (`det-cli serve`): replaces `shutdown_timeout`; now returns `!` since it always exits. - `run_headless()` (`det-cli headless`): same; retains early-return error path for config failures before the server starts. - one-shot tool path (`main`): replaces `Ok(())` tail; exit code from the block_on result. `backend.shutdown()` (persister drain) is kept in `shutdown_wallet_backend` and `run_headless` for correctness — it ensures no half-written `TokenBalanceChangeSet` is abandoned — but it is no longer expected to stop the coordinator threads before the runtime tears down. Safety: the tool result is printed and flushed before `process::exit`; all SQLite writes issued before the tool returned are transaction-committed; the platform-wallet-storage single-open lock is process-global and is reclaimed by the OS on exit, so the next invocation is unaffected. The upstream fix (joining the OS thread's `JoinHandle` in `quiesce()`) would be the library-level solution; this is the correct DET-side mitigation.

From 51a12f810f62357481e7d9c0a02ed5cd5933a6d9 Mon Sep 17 00:00:00 2001 From: Lukasz Klimek <842586+lklimek@users.noreply.github.com> Date: Mon, 22 Jun 2026 12:42:25 +0200 Subject: [PATCH 22/27] fix(mcp): address all PR #864 review findings (B1 S1-S7 H1 H2) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit H2: Extract masternode tools to src/mcp/tools/masternode.rs, rename to masternode_identity_load / masternode_credits_withdraw. B1: Fix is_platform_address_string panic on non-ASCII input — use as_bytes() throughout instead of str byte-slicing; add non-ASCII regression test. H1 + S1: Add Deserialize + JsonSchema to model::secret::Secret (feature- gated to mcp/cli). Change MasternodeIdentityLoadParams private-key fields from String to Secret so keys are mlock-ed from deserialization, before any SPV wait. S2: Call decode_identity_id before ensure_spv_synced in the LOAD tool so a malformed ProTxHash is rejected immediately rather than after a 10-min sync. S3: Add impl Display for KeyMode in masternode_input.rs; replace three literal "owner"/"transfer" sites with .to_string() so the canonical string is defined once. S4: Rewrite TC-MN-050 and TC-MN-051 to call MasternodeCreditsWithdraw::invoke() through a DashMcpService, exercising key-mode resolution, the payout-address echo, and the SPV gate. S5: Fix headless shutdown to also drain the initial context's wallet backend when the network was switched after startup (Arc::ptr_eq guard). S6: Restructure start_stdio to always call shutdown_wallet_backend even when serve() or waiting() returns an error. S7: Dispatch MigrationTask::FinishUnwire from ensure_spv_synced in standalone/headless mode where the GUI frame-loop never runs.

charset=UTF-8 Content-Transfer-Encoding: 8bit - Rename MasternodeCreditsWithdraw → MasternodeWithdraw and tool name masternode_credits_withdraw → masternode_withdraw (CLI: masternode-withdraw) per spec; all callers and tests updated. - S5 (network_switch backend drain): move the outgoing-backend drain from headless.rs to the swap_context callsite in NetworkSwitch::invoke, so every network switch immediately drains the replaced WalletBackend rather than waiting until process exit. headless.rs simplified back to draining only the active (current) context. - Docs: update MCP.md and CLI.md to reflect new tool names, corrected key handling description (params are now typed Secret, not plain String).

Fix: capture the actual WIF value before it is moved into load_task() (renamed wrong_key_wif, cloned at the call site), then assert !display.contains(&wrong_key_wif) and !debug.contains(&wrong_key_wif). The test is #[ignore] (backend-e2e); confirmed it still compiles. Fix A (LRis4): src/model/secret.rs Deserialize impl doc Removed the inaccurate "without ever living as a plain String" claim. The impl does ::deserialize(), creating a transient String before Secret::new consumes it. New wording: "deserializes into a transient String, then moves it into the zeroizing/mlock'd buffer and drops the transient, so no long-lived plain String copy persists." Fix B (LRit_): src/mcp/mod.rs start_stdio doc Removed "preventing panics from timer registration during runtime shutdown" — shutdown_wallet_backend does NOT join coordinator OS threads so it does not prevent that panic. New wording: "This does not prevent the coordinator timer-wheel panic that occurs on Tokio runtime drop — shutdown_wallet_backend does not join coordinator OS threads. std::process::exit in the caller is the deterministic mitigation."
