Phase 5. `press.mantra.desktop.MainKt` has been named by the compose.desktop block since before this work started and did not exist; now it does, and `./gradlew :composeApp:run` opens a window. **The window opens onto a passphrase gate, not onto the app.** That is phase 3 landing here rather than there, and it was not in the plan. keyStoreEncryption(keyName, plainText) takes no secret, because on android the OS keystore serves keys without asking anybody anything -- so a passphrase scheme needs an unlock the expect signature cannot express. MainKt calls JvmKeyStore.unlock before MantraApp is composed, off the ui thread, because Argon2id at 64 MiB is deliberately slow enough to stop the window painting. The gate says on its face that this build is not for real funds. One application directory is handed to both the mantra and the phoenix context, so a single install keeps a single place on disk rather than two named after different projects. **MantraDatabaseJvmTest is the part worth keeping.** Running the app proves the window paints; it proves nothing about Room, because the gate stops before anything touches the database. Six tests now open it: the schema is created, a profile survives a write and a read, upsert replaces rather than duplicates, the @Transaction relation query behind findChatRoomById reads back, a soft-deleted room stops being found, and the on-disk builder writes under the context directory rather than java.io.tmpdir. This is the first time this database has been opened anywhere but android, and it covers exactly what the compiler cannot see -- that Room's ksp output for this target is usable, that the *host* SQLite native loads where the android artifact's would not, and that the 58 queries forced from blocking to suspend still return what they stored. Both of that test's first drafts were wrong in ways worth keeping the scars of. Every write failed with SQLite error 787 because Profile has a foreign key onto NostrEvent and the test never created the parent row -- which is evidence rather than an annoyance, since a schema whose constraints were quietly off would have let all of it pass. And Kind is a typealias for Int, not a constructor. Window sizing is 480x900: a starting size that does not immediately misrepresent layouts only ever exercised at phone widths, not a considered desktop layout. That, along with back handling and any ui offering an nfc affordance, is the shakeout this phase names and does not do. Verified, all five green: :composeApp:compileKotlinJvm, :composeApp:compileDebugKotlinAndroid, :composeApp:testDebugUnitTest (52), :composeApp:jvmTest (6), and the fork's :library:jvmTest (97). Not verified: nothing past the gate. No seed has been written, no business started, no relay contacted. A gradle `run` killed with SIGTERM reports BUILD FAILED with exit value 143 -- that is the signal, not the app. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>

Notes on the parts of this app whose behaviour is not recoverable by reading the code alone — where the reasoning lives in a protocol, a failure mode that is silent, or a decision that looked arbitrary and was not.

Start with the ceremony if you are new to this area; the other two both assume it. Read the skipped-keys note before debugging any "the other device never got it" report — it is silent, and it looks like every other kind of delivery failure.
