feat: CancelOrderRequest.pretrade_only — refuse to fall through to the dispute cancel - #944
Conversation
…e dispute cancel `CancelOrder` from the daemon key serves two very different intents: the solver's dispute resolution (cancel + refund seller) and, since #939, the operator's cancel of a still-pending order. A tool that means the latter (`mostro-cli admcancelpending`) had no way to say so: a mistyped id belonging to a dispute the daemon has taken would resolve that dispute and report a "pending order cancelled" success (Codex review on mostro-cli#191). Add `optional bool pretrade_only = 3` to `CancelOrderRequest`. When set the service looks the order up first and refuses anything that is not `pending` / `waiting-taker-bond` with `success = false` and the order's status in `error_message`, before any handler runs. Unset keeps the existing behaviour, so older clients are unaffected. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PWN1jHfoZxfjusDVB9n3GW

WalkthroughThe Cancel Order RPC adds an optional ChangesPre-trade cancellation
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change adds a safety option intended to prevent pending-order cancellation from resolving disputes, but the documented command example does not enable that option and the restriction is not rechecked if the order changes state between validation and execution. Users could therefore still trigger dispute and escrow-cancellation behavior in these cases; the documentation and enforcement path should be corrected before merge.

…spute; doc fixes Codex review: `CancelOrder` is generic — with a mistyped id belonging to a dispute the daemon has taken, `admcancelpending` would resolve that dispute and print a "pending order cancelled" success. The daemon now takes `CancelOrderRequest.pretrade_only` (MostroP2P/mostro#944) and refuses anything that is not `pending` / `waiting-taker-bond`; the CLI sets it (`AdminRpcClient::cancel_pending_order`). Wire test pinned. CodeRabbit: token requirement stated conditionally in commands.md; README env table says "three commands"; loopback restriction scoped to SetMaintenanceMode only.

When this check accepts a pending order, its result becomes stale before call_admin_cancel re-reads the row: normal Nostr actions run concurrently with the RPC server, and the call can also wait for the RPC Lightning mutex. If the order advances and enters dispute in that interval, admin_cancel_action follows its dispute branch and can cancel the escrow despite pretrade_only = true, defeating the safety guarantee and potentially refunding the seller unintentionally. Pass the restriction into the handler and apply it to the same fetched order used to choose the cancellation branch, or otherwise make the check and branch atomic.

CodeRabbit: proto3 drops unknown fields, so against a mostrod older than MostroP2P/mostro#944 the `pretrade_only` flag is silently ignored and `CancelOrder` could still resolve a dispute the daemon has taken. Gate the command on `GetVersion` before any RPC that could touch an order: `ensure_pretrade_only_enforced` requires mostrod >= 0.18.7 (the first release with #944; `MIN_DAEMON_FOR_PRETRADE_ONLY`) and refuses older or unparseable versions with an explicit "upgrade mostrod" error. Adds the `GetVersion` request/response types and client method. Co-Authored-By: Claude Fable 5.1 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01PWN1jHfoZxfjusDVB9n3GW
Review follow-ups on the pretrade_only guard: - The "use the dispute flow (AdminCancel / AdminSettle)" hint was appended to every refusal, but it is only actionable when the order is actually in dispute; for active / fiat-sent / success / ... that flow is refused too, so the operator was sent to a second error. Append it only when the status is dispute. - Compare statuses with `Order::check_status` like admin_cancel.rs does instead of matching against `to_string()`. - docs/RPC.md: the client example was missing the new field and no longer compiled with prost; note that an older daemon silently drops the flag.
