Public Execution Architecture
The Forge Pool API exposes a single public execution architecture centered on a stable execution contract.
Clients interact with one consistent interface regardless of the execution strategy, workload family, or runtime implementation used internally. The public architecture intentionally abstracts orchestration details so the execution platform can evolve without changing client integrations.
This document describes the architectural responsibilities visible through the public API rather than the internal implementation of the execution runtime.
Public Architecture
From the perspective of an API client, every execution follows the same conceptual path.

Architectural Responsibilities
The public execution architecture is organized into clearly separated responsibility layers.
| Layer | Responsibility |
|---|---|
| Forge Pool API | Accept authenticated execution requests |
| Execution Contract | Define workload semantics through versioned primitives, profiles, and execution policy |
| Planetary Kernel | Plan and coordinate distributed execution |
| Distributed Execution | Execute workload shards across participating runtime infrastructure |
| Verification | Produce execution evidence, replay metadata, and artifact references |
| Response | Return domain output together with execution metadata |
Each layer represents a public architectural responsibility rather than a specific implementation component.
Stable Public Boundary
The Forge Pool API defines a stable boundary between clients and the execution platform.
Clients interact with:
- one public execution endpoint
- one canonical execution envelope
- one execution lifecycle
- one verification model
- one replay discipline
Everything beyond this boundary is considered part of the execution runtime and may evolve independently.
Execution Responsibilities
Every execution submitted through the public API follows the same responsibility model.
Request Acceptance
The public API authenticates the request, validates the execution contract, and establishes execution authority.
Execution Planning
The Planetary Kernel determines how the requested workload should be planned according to the selected primitive, execution profile, execution policy, and runtime capabilities.
Distributed Execution
The runtime executes workload shards across participating execution infrastructure while preserving deterministic execution semantics.
Verification
Execution metadata, replay references, artifacts, and runtime evidence are collected throughout execution to support independent verification.
Response Generation
The execution platform returns the reduced domain result together with the metadata required for inspection and replay.
Runtime Evolution
The public execution contract intentionally separates client integrations from runtime implementation.
Planning strategies, scheduling algorithms, execution topology, verification mechanisms, and orchestration components may evolve without changing the public API.
This architectural separation allows the execution platform to improve continuously while maintaining long-term compatibility for clients.
Higher-Level Execution Surfaces
Several platform surfaces build on top of the same execution contract.
Forge Studio
Provides interactive execution, workflow composition, inspection, and verification.
Adapters
Translate domain-specific inputs into canonical execution requests.
Labs
Provide reference implementations, vertical workflows, and experimental execution patterns built on the public execution contract.
These surfaces compose execution workflows without changing the underlying execution model.
Architectural Principle
The Forge Pool API documents execution behavior rather than runtime topology.
Clients integrate with a stable execution contract.
The execution platform remains free to evolve internally while preserving deterministic behavior, replay compatibility, and verification guarantees.
Why This Architecture
Separating the public execution contract from the internal runtime provides several long-term benefits.
- stable client integrations
- independent runtime evolution
- extensible primitive families
- improved scheduling strategies
- infrastructure portability
- verification-first execution
- deterministic replay compatibility
The result is an execution platform that can evolve internally without requiring changes to the public interface.

Final Note
The public API intentionally exposes architectural responsibilities instead of implementation components.
This distinction allows Forge Pool to maintain a stable execution contract while continuously evolving the distributed execution runtime behind it.
Understanding the public execution architecture is sufficient to understand every capability exposed through the Forge Pool API.
