## What it is
Manifold is a Clojure library providing building blocks for asynchronous programming: deferreds for single async values and streams for ordered sequences of async values. It also acts as a translation layer between incompatible async abstractions like core.async channels, Java BlockingQueues, and lazy sequences.

## Use cases
- compose asynchronous workflows in Clojure without raw callbacks
- bridge between core.async channels and Java BlockingQueues
- process streams of async values with backpressure
- represent async results that can carry errors like futures
- unify event-driven abstractions across different libraries

## When to avoid
- you're not on the JVM/Clojure ecosystem
- you only need simple core.async channels without compatibility needs
- you need a maintained license-guaranteed dependency for strict compliance (no explicit license listed)

## Facets
- artifact type: library
- maturity: active
- function: concurrency, streaming, middleware
- domain: developer-tools, backend, microservices
- platform: jvm, jvm-scripting
- tags: clojure, async, deferreds, streams, event-driven, backpressure, core-async-compat
