- mana-notify integration in cards-server: PR-create notifies the
deck owner, merge/reject notifies the PR author. Fire-and-forget
via lib/notify.ts so a notify-service outage never rolls back a
domain action. ExternalIDs are deterministic (cards.pr.{event}.{id})
so retries dedupe.
- <CardDiscussions> on the learn page: collapsed by default, opens
via "💬 Diskussion" alongside the "✏️ Verbessern" trigger. Resets
whenever the current card changes so the panel doesn't bleed
between flashcards.
- MARKETPLACE_PLAN.md §13a — known limitations: PR-merge is
stale-blind (no rebase yet), diff-preview flat, threading 1-level.
