> Lightweight Orchid integration layer with pluggable execution strategies

## Pages

## Modules

- [Oi](Oi.md): Oi means Orchid integration.

- [Oi.Compile.Bundle](Oi.Compile.Bundle.md): Container for a compiled Orchid recipe and its associated metadata.
- [Oi.Compile.Planning](Oi.Compile.Planning.md): Execution plan built from compiled Bundles.
- [Oi.Compile.Planning.Plan](Oi.Compile.Planning.Plan.md): Ordered sequence of stages.
- [Oi.Compile.Planning.Stage](Oi.Compile.Planning.Stage.md): A single execution barrier.
- [Oi.Compiled](Oi.Compiled.md): Static compilation product: bundles + execution plan.
- [Oi.Dispatch](Oi.Dispatch.md)
- [Oi.Dispatch.Config](Oi.Dispatch.Config.md): Immutable dispatch configuration.
- [Oi.Dispatch.Drafting](Oi.Dispatch.Drafting.md): Temporary result store for a single dispatch pass.
Holds computed outputs keyed by Orchid io_key (e.g. `"pred_step|result"`),
which is already globally unique. Workers read dependencies from here;
the dispatcher merges per-stage deltas back after each barrier.

- [Oi.Dispatch.Orchestrator](Oi.Dispatch.Orchestrator.md): Orchestrates barrier-synchronized execution of plan stages.
- [Oi.Dispatch.Worker](Oi.Dispatch.Worker.md): Executes a single Bundle in isolation.
- [Oi.Executor](Oi.Executor.md): Pluggable task execution strategy for stage fan-out.
- [Oi.Executor.Sync](Oi.Executor.Sync.md): Serial executor — runs all tasks in the calling process.
- [Oi.Executor.TaskSup](Oi.Executor.TaskSup.md): Task.Supervisor-backed executor — concurrent fan-out with crash isolation.
- [Oi.Flowgraph](Oi.Flowgraph.md)
- [Oi.Flowgraph.Macro](Oi.Flowgraph.Macro.md)
- [Oi.Result](Oi.Result.md): Execution result: the final drafting memory.
- [Oi.Runtime.Registry](Oi.Runtime.Registry.md): Local process storage for Oi sessions.
- [Oi.Runtime.Session](Oi.Runtime.Session.md): Session seperates whole application into seperal spaces where contains different
steps, independent [symbionts](https://orchid-symbiont.hexdocs.pm/) and storages.

- [Oi.Runtime.Session.Instances](Oi.Runtime.Session.Instances.md): Instance Supervisor.
- [Oi.Step](Oi.Step.md): 轻量级声明式语法层，在 `Orchid.Step` / `OrchidSymbiont.Step` 之上提供简易
API，并产出 `__node_spec__/0` 供 topology 集成。
- [Oi.Topology.Cluster](Oi.Topology.Cluster.md): Cluster dependencies based on user selections and dependency relationships at the front end
to achieve parallel control.
- [Oi.Topology.Graph](Oi.Topology.Graph.md): The pure mathematical representation of the DAG.

- [Oi.Topology.Graph.Edge](Oi.Topology.Graph.Edge.md): A directed edge representing data flow between two node ports.
- [Oi.Topology.Graph.Node](Oi.Topology.Graph.Node.md): A pure data representation of a computation step in the DAG.
- [Oi.Topology.Graph.PortRef](Oi.Topology.Graph.PortRef.md): A container based on the node/port representation, used to dynamically generate Orchid keys.
