Dagger-based verticle deployer with multi-instance and priority support

Event bus service dispatch with contract-first interfaces and resilience policies

Timer-based cron job scheduling with EVERY_INSTANCE and SINGLE_INSTANCE execution modes

Host-neutral application lifecycle runner: drives ordered startup steps and verticle deployment phases from a VertiqueApplicationComponent, with deterministic failure teardown

Format-agnostic Kafka runtime: serde SPI, producer/consumer infrastructure, and event bus dispatch

Persistent delayed job queue: enqueue service, polling verticle, and handler registration

JUnit 5 test-support for booting a Vertique application in one line: VertiqueAppExtension owns the awaited startup/teardown so integration tests never hand-write the bootstrap dance

Host-neutral core application starter composing the Vert.x, config parsing, deployment, and core lifecycle modules

PostgreSQL-backed inbox/outbox persistence: PgInboxRepository, PgOutboxRepository, Flyway DDL, and Dagger module

PostgreSQL persistence for workflow state machines: instance/history/dedup repositories, PgWorkflowEngine, optimistic concurrency, Flyway migrations.

Workflow timers and signal-wait timeouts: transactional delayed-job enqueue, source-of-truth timer table, orphan and dead-letter recovery.
