From 641174717c3d3194afcbbfa591c5222f8e745c04 Mon Sep 17 00:00:00 2001 From: MechaCat02 Date: Fri, 10 Jul 2026 23:05:37 +0200 Subject: [PATCH] fix(user-flow): close offline-queue, export, session, ban & realtime gaps MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Comprehensive user-flow review across guest/host/admin roles, then fixes with e2e regression guards. Highlights: - Offline upload queue auto-resumes on reconnect: network errors keep items pending (not error), 4xx are terminal (no infinite retry), quota exhaustion returns a distinct 413; queue cap + dedup. - Export lifecycle: release atomically locks uploads; reopen invalidates and re-release regenerates the keepsake; workers claim their job atomically so a reopen->re-release can't corrupt the ZIP; startup re-spawns interrupted exports. - Sessions slide on activity (no 30-day cliff); JWT expiry deferred to the revocable session row; sign-out-everywhere + revoke-on-PIN-reset. - Ban always hides content (v_feed / find_visible_media / export filter is_banned) but stays a read-only ban per USER_JOURNEYS §10 — sessions are not revoked, read access + keepsake download preserved. - Realtime: server-clock SSE delta cursor; event-closed/opened drive the UI live; feed_delta rate-limited; like returns {liked, like_count} to fix multi-device drift; lightbox live comments; diashow delta backfill. - Forgotten-PIN in-app request flow; simultaneous same-name join returns 409; quota increment is transactional; operator floor. Adds e2e/specs/10-flow-review/ (offline resume, export integrity, deterministic anti-race guard) and updates existing specs for the new contracts.
