Summary

Mortsom's bond family (eight black-box scenarios driving the real app through the automation contract) ran live against main with [anti_abuse_bond] enabled on both sides. Seven scenarios pass with this patch; the eighth fails on a daemon defect (MOSTRO-006), not on the app. The gaps this closes, each found by a live run:

  • Trade screen read a bonded take as an open order. The screen polls the public book first, whose pending hid the row's waiting-taker-bond. get_order yields the row's bond window when the book says pending.
  • A bond slashed by a solver read timeout. mostrod publishes an admin cancel/settle as plain canceled/success on Kind 38383 before the admin-canceled/admin-settled message; the terminal guard refused the later verdict, and bond-slashed inferred a timeout from the Canceled row. admin_verdict_refines lets the verdict refine the plain terminal the book wrote.
  • trade.bondClaim.open was never in the accessibility tree. The claim banner's merged automation id swallowed its own button; the card is merge: false.
  • bond.claim.status was never on screen. The readout was a SizedBox.shrink(), which gets no semantics node on desktop; it has a size now.
  • order.create.fiat_amount had merged with the inline currency selector into one node (the Linux driver rejects a node with two ids); the id sits on the text field alone.
  • appbar.back on the create form and the payment-method picker, and the maker's pay-bond screen pushed over /my_order so it has one.
  • keys.public_key restored on the account screen.
  • The claim banner on the maker's own-order screen. A taker slashed on the waiting-state timeout sends the order back to the maker as pending, so the maker lands on /my_order, which offered no claim; the banner is rendered there as on the trade detail.

docs/automation-contract.md is updated where the contract changed.

Test plan

  • cargo test in rust/ (new tests: bond_window_tests, an_admin_verdict_refines_the_plain_terminal_the_book_wrote, terminal_trades_block_replayed_status_syncs extended)
  • cargo clippy -- -D warnings, cargo check --target wasm32-unknown-unknown, flutter analyze (pre-commit hook)
  • Mortsom bond family live on Linux (regtest stack, mostrod v0.18.7, bonds on both sides): taker_bond_released_after_trade, taker_bond_declined, seller_taker_bond_then_escrow, maker_bond_locked_before_publish, maker_bond_abandoned, taker_bond_slashed_by_solver, bonds_released_by_solver_ruling accepted
  • taker_bond_slashed_on_timeout: accepted on a daemon built from fix(bond): fix the payout recipient at slash time so a timeout slash pays the maker mostro#964 (fixes MOSTRO-006); fails on v0.18.7, where the maker is never offered the share

Summary by CodeRabbit

  • New Features

    • Added a bond-claim banner to order details, making available payout actions easier to find.
    • Improved navigation for orders awaiting maker-bond payment so returning takes you back to the order.
    • Added clearer automation support for account identity verification and order/payment controls.
  • Bug Fixes

    • Corrected order statuses when bond-window information is available.
    • Allowed administrative cancellation or settlement decisions to update local order status correctly.
    • Improved visibility of payout status information on desktop platforms.

Mortsom's bond family, run live against main, found these gaps between
the app and docs/automation-contract.md:

- The trade screen polls the public book first, whose `pending` hid the
  row's `waiting-taker-bond`, so a take parked on the taker's bond read
  as an open order. `get_order` yields the row's bond window when the
  book says `pending`.
- mostrod publishes an admin cancel/settle as plain `canceled`/`success`
  on Kind 38383 before the `admin-canceled`/`admin-settled` message, and
  the terminal guard refused the later verdict; a bond slashed by a
  solver then read `timeout`. An admin verdict may refine the plain
  terminal the book wrote.
- The claim banner's merged automation id swallowed its own button, so
  `trade.bondClaim.open` was never in the tree; the card is `merge:
  false`. The claim screen's `bond.claim.status` readout was a zero-size
  box, which gets no semantics node on desktop; it has a size now.
- `order.create.fiat_amount` had merged with the inline currency
  selector into one node; the id sits on the text field alone.
- `appbar.back` on the create form and the payment-method picker, and
  the maker's pay-bond screen pushed over `/my_order` so it has one.
- `keys.public_key` restored on the account screen.

Each Rust change has a unit test.

Review Change StackReview Change Stack

Walkthrough

The change updates order-status reconciliation, bond-claim navigation and presentation, identity public-key automation, and automation identifiers for order forms and payment methods. Documentation and tests cover the updated automation contract.

Changes

Order state and automation

Layer / File(s) Summary
Order state reconciliation
rust/src/api/orders.rs, rust/src/mostro/status.rs
Pending book status can use the local bond-window status. Matching admin verdicts can refine terminal statuses. Tests cover both paths.
Bond claim flow
lib/features/order/screens/add_order_screen.dart, lib/features/order/screens/my_order_screen.dart, lib/features/order/screens/bond_payout_invoice_screen.dart, lib/features/trades/widgets/bond_claim_banner.dart
Maker-bond payment opens above the order screen. The order screen includes the bond-claim banner. Bond status and banner controls expose separate semantics nodes.
Account identity readout
lib/core/automation/automation_ids.dart, lib/features/account/screens/account_screen.dart, test/features/account/account_screen_test.dart
The account screen loads the identity public key and exposes it through a hidden automation readout. Tests cover loaded, loading, and layout states.
Automation surface
docs/automation-contract.md, lib/features/order/screens/payment_method_picker_screen.dart, lib/features/order/widgets/underline_amount_field.dart, lib/features/order/widgets/amount_section.dart
Order-form and payment-method automation identifiers are applied to separate controls. The contract documents range pricing, currency-node separation, and appbar.back. Formatting-only changes do not alter behavior.

P2 Badge Delay exposing the public-key identifier until it is loaded

On the first frame, _publicKey is necessarily null because _loadPublicKey() is asynchronous, yet keys.public_key is already discoverable with an empty label. A black-box driver can therefore find the identifier immediately after opening Account and read '' instead of the full key promised by the automation contract, making identity checks timing-dependent; render this readout only once the key is available.

Fixed in 2678382. The readout is rendered only once the key is loaded (if (_publicKey case final key?)), so a driver that finds keys.public_key reads the full key; before that the identifier is simply absent. Covered by a test that holds the load open and asserts the node is missing, then completes it and asserts the node appears. A debugPublicKey seam feeds the test.

P2 Badge Keep the automation-only node out of the account layout

Adding this as the first BackupFillViewport.blocks entry does not cost only one pixel: that widget inserts its configured 11-pixel gap before the next block, so every Account variant moves its visible first card down by 12 pixels (and can move overflowing content/footer as well). The existing account_15a_* and account_15b_* golden images were not updated, so the mandated Flutter test suite will fail; place the semantics node somewhere that does not participate in the spaced block list.

Fixed in 2678382, and this was the failing check: the six account_15* goldens failed on the 12 px shift. The node now sits over the viewport in a Stack(fit: expand) as a 1×1 Positioned child, outside the spaced block list, and paints nothing, so no card moves. The goldens pass unchanged, and a test asserts the banner's top-left is identical with and without the readout.

A taker slashed on the waiting-state timeout sends the order back to
the maker as pending, so the maker lands on their own-order screen,
which carried no claim banner: the share was reachable only through
the notification. The banner is rendered there as on the trade detail.

The keys.public_key readout sits over the viewport in a Stack, not in its spaced block list, so no card moves and the account goldens are unchanged. It is rendered only once the key is loaded, so a driver that finds it reads the full key, never an empty label. A debugPublicKey seam and three tests: the label, the absence until loaded, the unchanged card position.
