Closes #883. Part of #674.

Type

fix

What changes and why

The import screen read the node's capabilities once, in _load. On a cold start the node's Kind 38385 info event can arrive after the screen opened, and until then reputation_support::get returns the default with no import_issuers: the screen said "This Mostro does not import reputation." and kept every action disabled until the user tapped Retry. The Reputation screen already handles this by rereading support every two seconds.

The import screen now does the same: a periodic read every two seconds, and when import_issuers appears or disappears it reloads (_load), which rereads privacy and identity and prefills a pending attestation as the first load would have. A fetch that retracts the capability blocks the actions again. The read is skipped while a load or an action is in flight.

Affected flow

Settings → Reputation → Import reputation (/import_reputation), on opening before the capability fetch finished, and on a node whose info event changes while the screen is open. Dart only: lib/features/reputation/screens/import_reputation_screen.dart. No Rust, bridge or localization change. No order or dispute status is touched.

Blast radius

  • The read is get_reputation_support(), a sync bridge call that reads a map in memory; one call every two seconds while the screen is open, as the Reputation screen already does. The timer is cancelled in dispose.
  • Reload only on change: _load runs only when import_issuers flips between present and absent, so a checked attestation is not withdrawn by the timer in the steady state. When it does flip, withdrawing it is right: the actions are blocked, or were blocked, in that state.
  • Spec: the import screen section of specs/004-mostro-p2p-client/contracts/reputation_transfer.md documents the reread.
  • Persisted data, other platforms, wire, daemon, automation identifiers: untouched.

Platforms tested

None by hand. See Manual testing.

Manual testing

Not run: this branch was verified with flutter analyze and flutter test only; I did not run the app against a node. The steps a person should run:

Setup

App built from this branch with flutter run -d linux (debug), identity in Reputation Mode, active node advertising reputation_import_issuers, relays slow enough (or the app started offline and connected after) that the info event arrives a few seconds after startup.

Steps

  1. Cold-start the app and, before its info event arrives, open Settings → Reputation → Import reputation.
    Expected: "This Mostro does not import reputation." with the actions disabled; within two seconds of the fetch finishing, the notice goes away, the identity npub shows and "Get it from lnp2pBot" and Check are enabled, without tapping Retry. On main: the notice stays until Retry (fails on main).
  2. Regression: on a node that does not import, open the screen.
    Expected: the notice stays, Retry still rereads the state.
  3. Regression: paste an attestation, Check, wait ten seconds.
    Expected: the checked card and Import stay; the timer does not withdraw them.

Not covered

Nothing was run by hand. iOS, Android, web: not run.

Screenshots

No visible change beyond the notice going away on its own; pending an app run.

Automated tests

First commit (test:), failing on main: test/features/reputation/import_reputation_screen_test.dart → the screen picks up the capabilities when they arrive after it opened, without Retry: a node that reads as not importing at open; after the fake's trust list appears and two seconds pass, the notice is gone, Check is enabled and the npub shows; after the list disappears again, the notice is back and Check is disabled.

07:45 +3100 ~4: All tests passed!

Checklist

  • cd rust && cargo fmt --check && cargo clippy -- -D warnings && cargo test pass locally — no Rust change
  • dart format --set-exit-if-changed ., flutter analyze and flutter test pass locally (flutter test summary line pasted under Automated tests)
  • Changed rust/src/api/ or an .arb: regenerated code committed in the same commit (CONTRIBUTING.md § Generated code) — neither changed
  • New or changed user-facing text: every locale updated, no hardcoded strings — no text change
  • Changed an automation identifier: coordinated in the linked issue (docs/automation-contract.md) — none
  • Protocol or transport change: impact on the daemon and other clients stated (CONTRIBUTING.md § Protocol / Transport Changes) — none
  • Behaviour or contract change: matching spec under specs/ or .specify/ updated
  • Commits are signed
  • I ran the Manual testing steps myself and can explain every line of this diff — the steps were not run; the diff is explained above

Summary by CodeRabbit

  • New Features
    • The reputation import screen now checks for changes in node import support while open. If support becomes available or unavailable, the screen updates automatically, so you can see the current status and available actions without retrying or reopening the screen.

Regression test for #883, failing on main: the capabilities that arrive
after the import screen opened are not picked up, so the node reads as
not importing until the user taps Retry.

Walkthrough

The import screen now polls node capabilities every two seconds. When import support changes, the screen reloads its state and updates its message and controls. The timer stops when the screen is disposed.

The screen polls support every two seconds and reloads when importIssuers availability changes. It skips refresh while loading or busy and cancels the timer on disposal. The contract documents the polling behavior. The widget test verifies that the unsupported message and Check control update when support appears or disappears.

A capability change during pending-attestation loading can leave the attestation waiting for a manual Check. This is a narrow, recoverable issue; the change is mergeable with owner awareness or a follow-up fix.

The description follows the repository template and covers the issue, change rationale, affected flow, blast radius, testing, screenshots, automated regression coverage, checklist, and AI assistance. Manual testing was not performed, but this limitation is clearly disclosed and the required reproduction steps are provided.

Full details: Linked Issues check

Explanation

Issue #883 requires the import screen to detect reputation-import capabilities that arrive after the screen opens, without requiring Retry. The PR summary reports a two-second reread of get_reputation_support(), reloads when import_issuers changes, skips reads during load or actions, and cancels the timer on disposal. The named widget test covers capability appearance and removal without Retry. The implementation and test satisfy the active coding requirement.

Full details: Out of Scope Changes check

Explanation

The reported changes are limited to the import screen, its regression test, and the matching reputation-transfer contract update. These changes directly support issue #883. The summary reports no Rust, bridge, localization, persisted-data, protocol, order, dispute, or other-platform changes. No unrelated change is demonstrated.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (3 skipped: 3 unsupported.)

Comment thread lib/features/reputation/screens/import_reputation_screen.dart Outdated
_loading turned false before _load awaited the pending attestation, so
a capability change in that window started a second load, and the
prefilled attestation was never checked. The read and its check now
count as part of the load for the timer, which waits for the next tick.
