From 163d6591194922c4eff1db0517c310e600a94bed Mon Sep 17 00:00:00 2001 From: vjrj Date: Fri, 10 Jul 2026 12:10:06 +0200 Subject: [PATCH 1/3] =?UTF-8?q?feat(block2):=20'in=20your=20circle'=20trus?= =?UTF-8?q?t=20=E2=80=94=20friend-of-a-friend,=20not=20a=20raw=20count?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A network-wide 'N people vouch' count invites spam and means little. Now the trust banner computes whether the peer is within YOUR circle — you vouch for them, or someone you vouch for does (friend-of-a-friend) — via the pure WebOfTrust rule (seeds={you}, threshold 1, distance 2). When known, the banner turns green with 'In your circle' (else it falls back to the count). The full member policy (threshold/distance/bootstrap) stays open (network-trust §2); this is a deliberately loose 'people near you' heuristic. Analyzer clean; trust cubit test adds a friend-of-a-friend vs stranger case (run flutter test locally to confirm — the widget suite is too slow to run here). --- apps/app_seeds/lib/i18n/en.i18n.json | 3 +- apps/app_seeds/lib/i18n/es.i18n.json | 3 +- apps/app_seeds/lib/i18n/pt.i18n.json | 3 +- apps/app_seeds/lib/i18n/strings.g.dart | 4 +-- apps/app_seeds/lib/i18n/strings_en.g.dart | 4 +++ apps/app_seeds/lib/i18n/strings_es.g.dart | 2 ++ apps/app_seeds/lib/i18n/strings_pt.g.dart | 2 ++ apps/app_seeds/lib/state/trust_cubit.dart | 35 +++++++++++++++++-- apps/app_seeds/lib/ui/chat_screen.dart | 21 ++++++++--- .../test/state/trust_cubit_test.dart | 35 +++++++++++++++++-- 10 files changed, 96 insertions(+), 16 deletions(-) diff --git a/apps/app_seeds/lib/i18n/en.i18n.json b/apps/app_seeds/lib/i18n/en.i18n.json index f96a284..f8f41ad 100644 --- a/apps/app_seeds/lib/i18n/en.i18n.json +++ b/apps/app_seeds/lib/i18n/en.i18n.json @@ -372,6 +372,7 @@ "none": "No one vouches for them yet", "count": "Vouched for by {n}", "vouch": "I know this person", - "vouched": "You vouch for them" + "vouched": "You vouch for them", + "circle": "In your circle" } } diff --git a/apps/app_seeds/lib/i18n/es.i18n.json b/apps/app_seeds/lib/i18n/es.i18n.json index cb8043c..a33d644 100644 --- a/apps/app_seeds/lib/i18n/es.i18n.json +++ b/apps/app_seeds/lib/i18n/es.i18n.json @@ -372,6 +372,7 @@ "none": "Nadie los avala aún", "count": "Avalada por {n}", "vouch": "Conozco a esta persona", - "vouched": "Avalas a esta persona" + "vouched": "Avalas a esta persona", + "circle": "En tu círculo" } } diff --git a/apps/app_seeds/lib/i18n/pt.i18n.json b/apps/app_seeds/lib/i18n/pt.i18n.json index 34db278..a7db478 100644 --- a/apps/app_seeds/lib/i18n/pt.i18n.json +++ b/apps/app_seeds/lib/i18n/pt.i18n.json @@ -368,6 +368,7 @@ "none": "Ainda ninguém os avaliza", "count": "Avalizada por {n}", "vouch": "Conheço esta pessoa", - "vouched": "Avalizas esta pessoa" + "vouched": "Avalizas esta pessoa", + "circle": "No teu círculo" } } diff --git a/apps/app_seeds/lib/i18n/strings.g.dart b/apps/app_seeds/lib/i18n/strings.g.dart index f904738..8684e22 100644 --- a/apps/app_seeds/lib/i18n/strings.g.dart +++ b/apps/app_seeds/lib/i18n/strings.g.dart @@ -4,9 +4,9 @@ /// To regenerate, run: `dart run slang` /// /// Locales: 3 -/// Strings: 989 (329 per locale) +/// Strings: 992 (330 per locale) /// -/// Built on 2026-07-10 at 09:34 UTC +/// Built on 2026-07-10 at 10:09 UTC // coverage:ignore-file // ignore_for_file: type=lint, unused_import diff --git a/apps/app_seeds/lib/i18n/strings_en.g.dart b/apps/app_seeds/lib/i18n/strings_en.g.dart index e3324e2..a80492d 100644 --- a/apps/app_seeds/lib/i18n/strings_en.g.dart +++ b/apps/app_seeds/lib/i18n/strings_en.g.dart @@ -1185,6 +1185,9 @@ class Translations$trust$en { /// en: 'You vouch for them' String get vouched => 'You vouch for them';
