…iration_seconds The waiting-state countdown was cosmetic and wrong on two counts: it hardcoded 900 s instead of the node's advertised `expiration_seconds` (Kind 38385 instance event), and it counted down to `OrderInfo.expiresAt` (the 24 h pending-order expiry) rather than the waiting-state deadline. Fix, extracted into a shared `waitingCountdownDeadline` helper so every surface agrees: - Pending orders keep counting to the 24 h pending expiry (`expiresAt`). - Waiting states (buyer-invoice / payment) count to the state-change deadline: the trade's `timeoutAt` when the daemon persisted one, else now + the node's `expiration_seconds`, falling back to 900 s only when the instance event omits it. Both data sources were already in Dart (no bridge regen): `expirationSeconds` on `MostroInstance` via `mostroNodeProvider`, and `timeoutAt` on `TradeInfo` via `tradeInfoProvider`. Applied on both surfaces that render the countdown — the trade-detail screen and the chat trade-state header — which shared the same `expiresAt` bug (the chat header showed ~30 days for a waiting-payment order). UI only informs; the daemon stays the authority on expiry (no local cancellation at zero). Device-verified on hardware: About advertises 900 s; a waiting-for-payment order shows 15:00 counting down on both the trade-detail screen and the counterpart chat header, matching.

Use the snapshot status while live status resolves.
Line 94 uses liveStatus ?? order.status. Line 102 passes only liveStatus. While tradeStatusProvider is loading, a known pending or waiting order.status produces no countdown.
Pass liveStatus ?? order.status to waitingCountdownDeadline. Add coverage for the provider-loading state.

Keep the fallback deadline stable.
When timeoutAtEpoch is absent, Line 46 derives the deadline from render time. TradeDetailScreen rebuilds every second, so it receives a new deadline and resets its remaining duration. The fallback countdown cannot reach zero.
Use a stable waiting-state start time, or use a shared cache keyed by order ID and waiting status. Do not derive now + window again during each build. Add tests for repeated resolution of the same waiting state without timeoutAtEpoch. Run flutter analyze and flutter test after the fix.

…k, clear on exit Addresses the CodeRabbit review: - Fallback deadline is now stable. When timeout_at is absent, the waiting-state deadline is anchored on the trade's startedAt (state-change timestamp) plus the window, not `now + window`. The helper no longer reads the clock, so the per-second rebuilds that drive the ticking UI can't slide the deadline forward and prevent it from reaching zero. Returns null when neither timeout_at nor a start anchor is available (no bogus countdown). - Chat header uses the order snapshot status (`liveStatus ?? order.status`) while tradeStatusProvider resolves, matching the status pill, so a known waiting/pending order still shows a countdown during the loading frame. - Trade detail clears the countdown when the resolved state has none (active / fiat-sent / terminal), so a stale countdown doesn't linger across the transition out of a waiting state. Added waiting_countdown_test.dart: pending/waiting/timeout_at/fallback/null branches, the 900 s default, and a regression test asserting the fallback deadline is stable across repeated resolutions. flutter analyze + test green.

Thanks, all three addressed in the latest commit. Fallback drift (major): good catch. Anchored the fallback on `TradeInfo.startedAt` + window instead of `now + window`, so the helper is now a pure function of its inputs the deadline no longer slides forward on the per-second rebuild. Added a regression test asserting stability across repeated resolutions. Returns null when neither `timeout_at` nor a start anchor is present. Snapshot status (minor): the chat header now passes `liveStatus ?? order.status`, mirroring the pill, so the countdown shows during the provider's loading frame. Clear on non-countdown transition (major): trade detail now clears the countdown when the resolved state returns null (active / fiat-sent / terminal), so no stale countdown lingers. Added `waiting_countdown_test.dart` covering all branches. `flutter analyze` + `flutter test` green." |

Problem
The waiting-state countdown was cosmetic and wrong on two counts:
900 s(trade_detail_screen.dart) instead of the node'sadvertised
expiration_secondsfrom the Kind 38385 instance event a valuealready parsed in Dart but only shown on the About screen.
OrderInfo.expiresAt(the 24 h pending-order expiry), notthe waiting-state deadline.
TradeInfo.timeout_atis written on take but wasnever read.
Fix
Deadline selection is now a shared pure helper,
waitingCountdownDeadline(
lib/features/order/utils/waiting_countdown.dart), so every surface agrees:expiresAt), unchanged.deadline: the trade's
timeoutAtwhen the daemon persisted one, elsenow + expiration_seconds, falling back to900 sonly when the node omits it.Both data sources were already available in Dart, so there's no FRB regen:
expirationSecondsonMostroInstance(viamostroNodeProvider) andtimeoutAtonTradeInfo(viatradeInfoProvider).UI only informs the daemon stays the authority on expiry (no local
cancellation at zero).
Scope note
The issue names Take Order / trade detail. While verifying, I found the chat
trade-state header (
trade_state_header.dart) had the identical bug it fedraw
order.expiresAtto its countdown chip and showed ~30 days (719:55:19)for a waiting-payment order. Since it's the same defect and a half-fix would be
inconsistent, I extracted the logic into the shared helper and fixed both
surfaces. Happy to split the chat-header change out if you'd prefer it narrower.
Testing
Device-verified on hardware (Nokia C31):
expiration_seconds = 900.trade-detail screen and the counterpart chat header matching, and matching
the node's advertised window.
