Phases 2.1/2.2/2.3, 3.1/3.2, 4, 5.2, and 6 of the launch-optimization plan
land together because they share a single set of seams and a single
benchmark report.
* InProcessWebsocketBuilder + LaunchFixtureRelay wrap quartz's existing
InProcessWebSocket + NostrServer (with EmptyPolicy) so any test can
drive a NostrClient against an in-memory relay seeded with arbitrary
events. Roundtrip verified by LaunchFixtureRelayTest.
* LaunchFixture builds a deterministic 50-note synthetic home-feed
snapshot from a fixed RNG seed (kind:1 + author kind:0 + kind:3 +
kind:10002). A real-world JSONL artifact is a drop-in replacement.
* NoteCard gets a stable testTag + a CompositionLocal-backed
onPlaced hook. Production overhead is one composition-local read
plus one null check per placement (default
LocalNoteCardInstrumentation = null).
* LaunchMarkers records named markers against TimeSource.Monotonic.
LaunchScenario.coldBoot drives the AccountManager (ViewOnly path)
+ DesktopLocalCache + RelayConnectionManager + LocalRelayStore
stack against the fixture relay and reports t_account_logged_in,
t_first_event, t_n_events.
* LaunchBenchmark runs 2 warmup + 5 measured iterations, computes
min/q1/median/q3/max, atomically writes the report file, and is
skipped by default — opt in via AMETHYST_BENCH=true. Baseline +
post-fix snapshots committed under desktopApp/benchmarks/.
* SubscribeBeforeConnectTest proves NostrClient / RelayPool queue REQs
issued before connect() and flush them when the connection comes up.
The bootstrap-config subscription in Main.kt drops its
`connectedRelays.first { isNotEmpty() }` + 30s withTimeoutOrNull gate
on the strength of that invariant — the subscription now fires
eagerly and recovers when no relay ever connects instead of silently
giving up after 30s.
All 274 desktopApp tests pass. No flaky tests introduced.
