Zixir v3.0.0 — AI automation release

This release adds full AI automation support: workflow orchestration with checkpointing, resource sandboxing, streaming/async, observability, and a cache layer. Plus universal improvements for binary serialization, tracing, sandbox results, and GenServer startup.

AI automation features

1. Workflow orchestration with checkpointing ✅

  • Files: lib/zixir/workflow.ex, lib/zixir/workflow/checkpoint.ex
  • Features: DAG execution, dependency management, automatic checkpointing, resume from failure, retry policies, dead letter queues
  • Usage: Build fault-tolerant AI pipelines that recover automatically

2. Resource limits & sandboxing ✅

  • File: lib/zixir/sandbox.ex
  • Features: Time limits, memory limits (e.g. "2GB"), CPU monitoring, automatic process termination, call depth limits
  • Usage: Prevent runaway AI processes from consuming all resources

3. Streaming & async support ✅

  • File: lib/zixir/stream.ex
  • Features: Async/await, parallel execution, lazy sequences, stream transformations (map, filter, batch), backpressure
  • Usage: Handle streaming AI responses (LLMs) and parallel model inference

4. Structured observability ✅

  • File: lib/zixir/observability.ex
  • Features: JSON logging, execution tracing with spans, Prometheus-compatible metrics, performance monitoring
  • Usage: Monitor AI workflows without manual intervention

5. Cache & persistence layer ✅

  • File: lib/zixir/cache.ex
  • Features: In-memory caching with TTL, disk persistence, database-like operations (insert/query/update), cache warming
  • Usage: Store intermediate results and avoid redundant computation

Universal improvements

Improvement Benefit
Binary serialization (instead of JSON) Handles all Elixir data types (tuples, atoms, PIDs, etc.); more reliable for internal state persistence
Span struct initialization Prevents KeyError in all tracing scenarios; works regardless of span lifecycle
Result wrapping in Sandbox Follows Elixir {:ok, result} / {:error, reason} convention; consistent across all sandboxed operations
GenServer startup handling Standard Elixir pattern for idempotent service startup; works in supervision trees and manual startup

Requirements

  • Elixir 1.14+ / OTP 25+
  • Zig 0.15+ (build-time; run mix zig.get after mix deps.get)
  • Python 3.8+ (optional) for ML/specialist calls

Quick start

git clone https://github.com/Zixir-lang/Zixir.git
cd Zixir
git checkout v3.0.0
mix deps.get
mix zig.get
mix compile
mix test
