Building on Quartz, the Kotlin Multiplatform Nostr library (com.vitorpamplona.quartz): NostrClient + a WebsocketBuilder, fetchAll/fetchFirst/fetchAllPages/publishAndConfirm, typed event builders, NostrSigner, NIP-19/NIP-05/NIP-44. Use in projects that depend…
Account, LocalCache, User/Note and feeds in commons/model + commons/feeds: per-user XState objects (.flow), FeedFilter/AdditiveFeedFilter, FeedViewModel. Use when adding an account setting or list, a feed, or choosing LocalCache vs account flows.
amy CLI in cli/: adding an `amy <verb>` command, Main.kt dispatch, Output.emit/--json contract, exit codes 0/1/2/124, ~/.amy layout, cli/tests harnesses. Use when touching cli/. Enforces the thin-assembly rule: logic goes to commons/quartz.
Android shim in `amethyst/`: MainActivity, AndroidManifest/intent filters, :napplet process, play/fdroid flavors, R8 + tools/r8-verify, permissions, Intent/Context ports. Use when editing amethyst/. NOT for screens/navigation (compose-expert).
NostrSigner in Amethyst: NostrSignerInternal (local key), NostrSignerRemote (NIP-46 bunker), NostrSignerExternal (NIP-55 Android app). Use when signing/encrypting, adding a signer kind, login flows, or debugging sign timeouts.
Shared Compose UI in `commonsUI/`: screens, components, the nav shell (`ScreenLayoutSpec`, `AppShellLayout`, Navigation 3 back stacks), component catalog, `RichTextParser`, Compose API/perf review. Use when writing or reviewing shared UI.
Desktop JVM shim in desktopApp/.../desktop/app/: AmethystDesktop window, DesktopMenuBar shortcuts, platform ports, OS keyring; run/package (:desktopApp:run, packageDmg/Msi/Deb/Rpm). Use when touching desktopApp. NOT for shared screens/navigation.
Quartz IEventStore/SQLite store contract (STORE-* rules) and NIP-50 search: filter semantics, replaceable/deletion/expiry writes, counts, FTS, which kinds are SearchableEvent. Use for store parity, geode, or making a kind searchable.
