Hongming Wang d8026347e5 chore: open-source restructure — rename dirs, remove internal files, scrub secrets
Renames:
- platform/ → workspace-server/ (Go module path stays as "platform" for
  external dep compat — will update after plugin module republish)
- workspace-template/ → workspace/

Removed (moved to separate repos or deleted):
- PLAN.md — internal roadmap (move to private project board)
- HANDOFF.md, AGENTS.md — one-time internal session docs
- .claude/ — gitignored entirely (local agent config)
- infra/cloudflare-worker/ → Molecule-AI/molecule-tenant-proxy
- org-templates/molecule-dev/ → standalone template repo
- .mcp-eval/ → molecule-mcp-server repo
- test-results/ — ephemeral, gitignored

Security scrubbing:
- Cloudflare account/zone/KV IDs → placeholders
- Real EC2 IPs → <EC2_IP> in all docs
- CF token prefix, Neon project ID, Fly app names → redacted
- Langfuse dev credentials → parameterized
- Personal runner username/machine name → generic

Community files:
- CONTRIBUTING.md — build, test, branch conventions
- CODE_OF_CONDUCT.md — Contributor Covenant 2.1

All Dockerfiles, CI workflows, docker-compose, railway.toml, render.yaml,
README, CLAUDE.md updated for new directory names.

System Architecture

Overview

The platform is fully distributed — workspaces can run on different machines and communicate via the A2A (Agent-to-Agent) protocol.

System Boundaries

The platform consists of four distinct systems:

+-----------------------------------------------------------+
|  canvas/              Next.js 15 frontend                  |
|  React Flow visual canvas, Zustand state, WebSocket        |
+-----------------------------+-----------------------------+
                              | HTTP + WebSocket
+-----------------------------v-----------------------------+
|  workspace-server/            Go (gin) backend                     |
|  Registry, hierarchy, event log, provisioner, bundles       |
+------+---------------------------------------+------------+
       | Postgres                               | Redis
+------v------+                       +---------v---------+
|  Postgres   |                       |     Redis         |
|  (Docker)   |                       |    (Docker)       |
+-------------+                       +-------------------+

       A2A HTTP (JSON-RPC 2.0) — direct workspace-to-workspace
+-----------------------------------------------------------+
|  workspace/  pluggable workspace runtime          |
|  LangGraph / DeepAgents / Claude Code / CrewAI / AutoGen   |
|  / OpenClaw + a2a-sdk                                      |
+-----------------------------------------------------------+
       |
+------v----------------------------------------------------+
|  Langfuse             Observability (Docker)               |
|  Traces every LLM call across all workspaces               |
+-----------------------------------------------------------+

Plugins

Shared skill/rule collections mounted into every workspace container at /plugins/:

plugins/
├── ecc/                    # Everything Claude Code
│   ├── rules/              # Always-on guidelines
│   ├── skills/             # Shared skills (coding-standards, tdd-workflow, etc.)
│   └── AGENTS.md           # Prompt fragment
└── superpowers/            # obra/superpowers
    └── skills/             # Shared skills (debugging, verification, etc.)

Plugins inject rules and skills into all agents automatically. Workspace-specific skills take priority over plugin skills (deduplicated by ID).

Data Flow Summary

  • Canvas <-> Platform: HTTP REST + WebSocket for real-time events
  • Platform <-> Postgres: Source of truth for registry, hierarchy, events
  • Platform <-> Redis: Ephemeral state — liveness, caching, pub/sub
  • Platform -> Workspace: Provisioning (tiered Docker deployment), discovery
  • Workspace <-> Workspace: Direct A2A (JSON-RPC 2.0) — platform not in path
  • Workspace -> Langfuse: Automatic LLM tracing
