From adee67cf0d038af75e7574185adc27f244330e53 Mon Sep 17 00:00:00 2001 From: Kayos Date: Fri, 27 Mar 2026 11:08:03 -0700 Subject: [PATCH] feat(wallet): payment card timeline item and raw event handling (Tasks 7+8) Task 7: Timeline Payment Card - TimelineItemPaymentView integration with TimelineItemEventContentView - Payment card rendering for both sender and recipient perspectives - Unit tests for TimelineItemPaymentContent Task 8: Raw Event Handling - Modified TimelineItemContentMessageFactory to intercept payment events - Added isSentByMe parameter propagation through content factories - FakePaymentEventSender for testing - Unit tests for TimelineItemContentPaymentFactory SDK Limitation Workaround: Since matrix-rust-sdk doesn't expose raw event sending or UnknownContent raw JSON, payment events are encoded as text messages with a marker: [cardano-payment:v1]{...json...} This falls back gracefully for non-wallet clients while enabling rich payment card rendering for wallet-enabled clients. --- BLOCKERS.md | 80 ++++++- .../event/TimelineItemEventContentView.kt | 6 + .../event/TimelineItemContentFactory.kt | 1 + .../TimelineItemContentMessageFactory.kt | 35 ++-
