Problem / Motivation

Synapse is becoming a backend-first, plugin-driven, worker-driven and event-driven AI platform.

As the system grows, debugging will become difficult without a dedicated local observability and diagnostics layer.

ECHO should become the local-only technical debugger and observability system for Synapse.

ECHO is not meant to be a normal AI agent like future assistant/automation agents. It should be the local technical nervous system of Synapse:

debug runtime
observability layer
event inspector
workflow tracer
local recovery helper
plugin and worker diagnostics tool
explainability layer for agent/tool decisions

#43 External Worker Runtime for Non-Java Plugins
#44 Synapse Node Agent for Linux Hosts, Homelabs and Infrastructure Integrations
#35 Workflow & Automation Ideas
#41 Local-First & Homelab-Oriented Deployment Philosophy

Proposed Solution

Design ECHO as a local-first diagnostics subsystem that can inspect and explain Synapse runtime behavior.

ECHO should help answer questions like:

Why did this workflow run?
Why did this plugin fail?
Why was this tool call denied?
Which provider handled this request?
Which worker executed this task?
Which capability check failed?
Which event caused this action?

Possible architecture:

Synapse Core
 ├── Event Bus
 ├── Plugin Runtime
 ├── Worker Runtime
 ├── Workflow Engine
 ├── Capability System
 ├── Audit Log
 └── ECHO
      ├── Runtime Inspector
      ├── Event Timeline
      ├── Trace Viewer
      ├── Plugin/Worker Diagnostics
      ├── Replay/Simulation Layer
      └── Safe Mode / Recovery Layer

Scope

This issue tracks the high-level ECHO architecture.

More detailed sub-issues should be created for:

ECHO event timeline and trace viewer
ECHO plugin/worker diagnostics
ECHO safe mode and recovery mode
ECHO workflow replay and simulation
ECHO local UI / CLI / TUI interface
ECHO explainability layer for AI/tool decisions

Local-Only Requirement

ECHO should be local-first and should not require cloud access.

Possible modes:

local dashboard page
CLI commands
optional terminal UI
localhost-only emergency panel
read-only diagnostics mode

ECHO should be safe to use in homelab and offline environments.

Security Requirements

ECHO must respect role/permission checks
sensitive secrets must never be printed directly
local-only mode should be available
read-only mode should be available
audit logs should show when ECHO actions were used
recovery actions should require explicit confirmation
remote access should be disabled by default

Priority

High / Strategic

ECHO could become one of the most important internal systems in Synapse because it makes the platform understandable, debuggable and safer as plugins, workers and workflows grow.
