Backend-driven UI toolkit: server describes component trees; client renders with plug-in components, generated registration, graceful degradation, client-side forms, server-driven theming, and per-user live updates.

Annotation-driven screenshot testing and interactive component browser for Compose: collects annotated composables into a registry, renders via real Compose runtime, records PNG goldens and diffs.

#test, #ksp, #image, #gradle-plugin, #desktop, #compose-ui, #compose-multiplatform, #compose, #code-generation

Distributed saga engine handling multi-step operations via interceptor chains across ordered phases; automatic compensation, suspend/resume with TTL, optimistic locking, and outbox-aware reliable event delivery.

#storage, #sql, #scheduling, #native, #ktor, #kotlin-native, #kotlin-coroutines, #http, #framework, #concurrency

Durable, transactional scheduler recording timers inside caller transactions, emitting "it is time" events (seconds precision), ensuring at-least-once delivery with idempotency keys and lateness tracking.

#sqlite, #sql, #sdk, #scheduling, #native, #kotlin-native, #database

Message broker on append-only log, splitting topics into partitions and segments; zero-copy FETCH via transferTo, long-poll consumers, per-partition writer actors, mmap/FileChannel writes, CRC32C-verified records.
