Admin dispute resolutions (admin-settled, admin-canceled, admin-took-dispute) were applied unconditionally: the status changed with no dispute in local state, and a dispute payload could materialize a resolved dispute on its own. They now
require local dispute state to back them, are not re-applied to an already-resolved dispute, and a payload can no longer re-point a tracked dispute at a different id. A dropped message raises no notification and does not navigate.

admin-canceled gets its own terminal status (canceled-by-admin, already rendered by the trade widgets) and the handleEvent case it was missing. It is no longer indistinguishable from a plain cancelation, and no longer reaches session deletion through the bond-cancel reconciler, which was only ever meant for Action.canceled. These orders stay under the "canceled" filter.

Resolution messages across the six locales now attribute the outcome to the admin and ask the user to confirm in their wallet, instead of stating that funds moved: the app reads neither the wallet nor the escrow.

Also documents that MostroFSM is not wired in — nothing imports it, and status is derived by OrderState._getStatusFromAction.

15 new tests across intake guard, status filter and resolution messages.
540 tests pass, flutter analyze clean.

@AndreaDiazCorreia, you've reached your PR review limit, so we couldn't start this review.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Walkthrough

The PR validates administrator dispute actions against local evidence, distinguishes administrator cancellations, suppresses side effects for rejected actions, updates synchronization and canceled-status filtering, and clarifies dispute-resolution messages across six locales.

Changes

Admin dispute resolution

Layer / File(s) Summary
Order resolution validation
CLAUDE.md, lib/features/order/models/order_state.dart, test/features/order/models/order_state_admin_resolution_guard_test.dart
OrderState validates dispute evidence and IDs, rejects forged or replayed administrator actions, preserves valid dispute state, and maps administrator cancellation to Status.canceledByAdmin.
Resolution notification and synchronization flow
lib/features/order/notifiers/abstract_mostro_notifier.dart, lib/features/order/notifiers/order_notifier.dart, lib/shared/utils/order_sync_helpers.dart, test/shared/utils/order_sync_helpers_test.dart
Notifiers suppress side effects for rejected actions. OrderNotifier resynchronizes before hydration and limits replayed synchronization requests.
Canceled status filtering
lib/features/trades/providers/trades_provider.dart, test/features/trades/status_filter_test.dart
The canceled filter matches both ordinary and administrator cancellations. Other filters still require exact status matches.
Resolution messages and UI validation
lib/l10n/intl_*.arb, test/features/disputes/dispute_resolution_message_test.dart
Translations and widget tests identify the administrator’s favored party and clarify order and wallet outcomes across supported locales.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🟡 Moderate · up to 1fa71

The PR tightens admin dispute handling, but synchronization can still be marked complete while a requested replay remains unresolved after retry exhaustion, preventing later updates from triggering recovery and potentially leaving users with stale dispute state. This should be fixed or explicitly accepted before merge.

Poem

A rabbit checked each dispute claim,
And matched the proof before the change.
Admin cancellations show their state,
Clear words explain each outcome.
Sync requests wait, then run in turn.

I would not approve this yet.

I re-read the current PR conversation and checked the current head (1fa71ad1a56b61df02724d11c9c80b0f4beb0f01). The main intake guard is directionally right, and the previous “status-only dispute is evidence” issue is fixed, but one data-integrity blocker still remains:

  • lib/shared/utils/order_sync_helpers.dart:29-32 still marks the notifier as hydrated when resyncRequested == true, the replay budget is exhausted, and the pass itself succeeded. That pass can still be missing the queued admin resolution that requested the replay. Once OrderNotifier sets _hydrated = true, a later onAdminResolutionRejected returns immediately, so recovery is permanently disabled for subsequent valid resolutions. The bounded replay cap is fine, but exhausting it must leave the notifier unhydrated/recoverable, not declare success for a history that is known to have a pending replay request. This matches the unresolved current thread at lib/shared/utils/order_sync_helpers.dart:32.

There is also an unresolved formatter nit in lib/features/order/notifiers/order_notifier.dart:53-55; I would not block solely on that if CI enforces formatting, but it should be cleaned up with the fix.

I could not run Flutter/Dart locally on this machine (flutter/dart are not installed), so my verification is code inspection plus the exact-head GitHub checks. The current build check is green, but the replay-budget recovery issue is still a correctness blocker for this PR's stated guarantee.

I still would not approve this head yet.

The previous blocker is fixed in the narrow sense: resolveSyncCompletion() no longer trades a pending replay for hydrated, so the notifier will not permanently disable recovery while it knows a queued resolution may be missing. CI is also green for this head.

However, the new fix removes the replay cap entirely, which leaves a different blocker:

  • lib/shared/utils/order_sync_helpers.dart:21-31 now returns SyncCompletion.replay for every resyncRequested, and lib/features/order/notifiers/order_notifier.dart:112-114 immediately starts another full sync() for that result. A forged/rejected admin resolution delivered while each pass is running keeps _resyncRequested true, so the notifier can be held in an unbounded full-history replay loop and never reach _hydrated = true. The new comment says the chain is self-limiting because it needs a fresh rejection during the pass, but rejected admin messages are exactly the hostile input this PR is guarding against; requiring a fresh one per pass is a rate limit imposed by the attacker, not a bound in the client.

Please keep the recovery behavior without turning it into an unbounded replay loop. For example, keep a max replay budget, but when the budget is exhausted return/stay unhydrated instead of claiming hydrated; that preserves future recovery without immediately scheduling infinite full storage reads. Add a regression test for the exhausted-budget + pending-replay case so it proves both properties: no hydration while replay is pending, and no automatic replay after the cap.

Approved.

I re-reviewed the current head (35bd30966a31cd395a937525c274428a1fa58c93) and the latest delta from the previous reviewed commit.

The prior blocker is fixed: resolveSyncCompletion() now keeps the bounded replay chain, but returns SyncCompletion.unhydrated instead of hydrated when the replay budget is exhausted with a replay still pending. That preserves both required properties: it does not permanently disable future recovery for a possibly-missing admin resolution, and it also does not let hostile rejected messages pace an unbounded chain of full history reads.

I also verified there are no current unresolved review threads, git diff --check origin/main...HEAD is clean, and the exact-head build check is green. I could not run Flutter/Dart locally because this machine does not have flutter/dart installed, so the executable verification here relies on the GitHub Actions build for that part.
