Oclaw Migration Guide

This repository is migrating from legacy oclaw/ runtime wiring to the new oclaw/ architecture root.

Current status

• oclaw/ is the target root for new code.
• oclaw/app_server/* compatibility modules have been removed.
• Gateway dispatch now routes through shared server_methods handlers for both WS and HTTP method endpoints.

Developer rules

• Add new business logic under oclaw/ (interfaces/application/domain/infrastructure/shared).
• Avoid adding new core logic into legacy oclaw/ modules.
• Keep oclaw/ changes limited to re-export or compatibility adaptation.
• Before deleting compatibility modules, use:
  • oclaw/docs/OCLAW_COMPAT_REMOVAL_CHECKLIST.md

Runtime notes

• Gateway HTTP method adapter: POST /gateway/method
• WS dispatch first resolves method handlers from shared dispatcher.
• Inbound payload use-case entrypoint: oclaw.runtime.application.gateway.process_inbound_payload_usecase
• HTTP app entrypoint moved to: oclaw.interfaces.http.fastapi_app
• WS entrypoint moved to: oclaw.interfaces.ws.entrypoint
• WS runtime bridge path: oclaw.interfaces.ws.runtime
• WS runtime implementation seam:
  • oclaw/interfaces/ws/runtime_impl.py
  • runtime.py points to this module as stable import surface.
• Server-method WS bridge extracted to:
  • oclaw/interfaces/ws/server_methods_bridge.py
  • legacy class now delegates dispatch/context construction to this bridge.
• Agent turn execution extracted to:
  • oclaw/interfaces/ws/turn_runner.py
  • legacy run_agent_turn now delegates to this module.
• WS request dispatch path is now single-source:
  • connected requests go through server_methods bridge first;
  • unknown methods return standardized invalid-request errors.
• Legacy WS handle_* and schema-specific validate helpers were removed from the class; runtime behavior now comes from dispatcher + bridge modules.
• WS schema access is now routed via:
  • oclaw/interfaces/ws/ws_schema.py
  • legacy gateway imports schema helpers through the oclaw namespace.
• WS schema implementation has been migrated to:
  • oclaw/interfaces/ws/schema_impl.py
  • no legacy oclaw/app_server/ws_schema.py dependency remains.
• WS auth + hello payload builders moved to:
  • oclaw/interfaces/ws/auth_and_hello.py
  • legacy gateway delegates resolve_ws_auth and build_hello_ok.
• WS frame/event emit helpers moved to:
  • oclaw/interfaces/ws/events.py
  • legacy gateway delegates send_res/send_event/emit_*.
• WS runtime helpers moved to:
  • oclaw/interfaces/ws/runtime_helpers.py
  • legacy gateway delegates _recv_frame and _handle_connect.
• WS main loop + close behavior moved to:
  • oclaw/interfaces/ws/runtime_loop.py
  • legacy gateway delegates run() and _close_ws().
• WS connected-request dispatch moved to:
  • oclaw/interfaces/ws/runtime_dispatch.py
  • legacy gateway delegates _dispatch_connected().

Extension source policy

• Primary source: oclaw/extensions/
• Legacy root extensions/ has been merged into oclaw/extensions/ and removed.

Prompt and skills policy

• Role context is loaded from oclaw/runtime/workspaces/*.
• Skills root priority:
  1. AIA_SKILLS_ROOT
  2. oclaw/runtime/skills
  3. skills/ (legacy fallback)
