IngotCluster

Iroh (iron, P2P QUIC) and Zenoh (brokered zenohd) in one Elixir cluster package.

gale   — Phoenix HTTP/3
ingot_cluster — Iroh + Zenoh (Hex: `ingot_cluster`)
dusk   — Zenoh + Iroh
orian  — BLAKE3 / S3 / S5 storage
zeiroh — Phoenix FLAME overlay

{:ingot_cluster, "~> 0.1", hex: :ingot_cluster}

# prefers a Burrito single binary (ERTS inside); else Mix escript

ingot_cluster match "a/**" a/b
ingot_cluster hash ./file --algo blake3
ingot_cluster put ./file

Inside a Mix project: mix ingot_cluster backends.

{IngotCluster,
 iroh: [alpns: ["ingot_cluster/1"]],
 zenoh: [connect: "tcp/127.0.0.1:7447", key: "ingot_cluster/cluster/**"]}

Add one of these in the host app (rustler pin clash if both):

{:iroh_beam, "~> 0.2"}   # Iroh
{:zenohex, "~> 0.10"}    # Zenoh

Zig NIF: key-expr match, FNV hash64, BLAKE3, XXH3. See HASH.md.

Fast path: orian. Built-in:

{:ok, cid} = IngotCluster.Storage.put(body)                    # memory, BLAKE3 CID
IngotCluster.Storage.put(body, backend: :s3, bucket: "b", unsigned: true, host: "127.0.0.1:9000", scheme: "http")
IngotCluster.Storage.put(body, backend: :s5, endpoint: "http://127.0.0.1:5050")

libcluster

config :libcluster,
  topologies: [
    iron: [strategy: IngotCluster.Strategy.Iroh, config: [alpns: ["ingot_cluster/1"]]],
    zenoh: [
      strategy: IngotCluster.Strategy.Zenoh,
      config: [connect: "tcp/127.0.0.1:7447", key: "ingot_cluster/cluster/nodes"]
    ]
  ]

Optional {:libcluster, "~> 3.5"} in the host app.

Phoenix FLAME

config :flame, :backend, {IngotCluster.FLAME.Backend,
  provisioner: :local,   # :docker | :fly | :k8s | :ec2
  overlay: :both,
  live: false}

provisioner is not Fly-only: local, Docker CLI, FLAME.FlyBackend, FLAMEK8sBackend, FlameEC2. Host app adds the matching Hex package. overlay::iroh, :zenoh, or :both. Optional {:flame, "~> 0.5"}.

Limits: this boots a local runner Task and may advertise {node, pid} on Zenoh. It does not start FLAME.Terminator, set FLAME_PARENT, or provision a remote BEAM node. Iroh/Zenoh cannot replace Fly/K8s boot; they can only discover existing nodes. Full eval: EVAL.md. Scaling (provision + overlay): SCALING.md.

libcluster strategies currently connect a staticconfig[:nodes] list; they do not yet subscribe to live Iroh/Zenoh membership.
