WebSocket Protocol

Real-time bidirectional event bus. Single connection per client.

Connection

ws://{host}{BASE_PATH}/ws?token={access_token}

Lifecycle:

• Server sends ping every 54 seconds
• Client must respond with pong within 60 seconds or disconnection
• Max message size: 4 KB
• Write deadline: 10 seconds

Event Envelope

All messages are JSON:

{
  "type": "event.type",
  "payload": { ... }
}

Room Subscription

Clients subscribe to rooms for scoped event delivery:

{ "type": "subscribe", "payload": { "room": "channel:uuid" } }
{ "type": "unsubscribe", "payload": { "room": "channel:uuid" } }

Event Routing Table

Prefix	Direction	Description
channel.created	→ client	New channel created
channel.updated	→ client	Channel metadata changed
channel.deleted	→ client	Channel removed
message.created	→ client	New message in subscribed channel
message.updated	→ client	Message content changed
message.deleted	→ client	Message removed
cursor.updated	→ client	Branch cursor moved
typing.start	↔ both	Participant started typing (payload includes participant_id, participant_type)
typing.stop	↔ both	Typing ended
participant.joined	→ client	Participant added to channel
participant.left	→ client	Participant removed from channel
participant.updated	→ client	Participant role changed
presence.update	→ client	Participant online/idle/offline status change
model.changed	→ client	Channel model roster changed
persona.updated	→ client	Persona metadata changed
kb.updated	→ client	Knowledge base changed
kb.document.status	→ client	Document processing status update
note.created	→ client	Note created
note.updated	→ client	Note content changed
note.deleted	→ client	Note removed
notification.new	→ client	New notification
notification.read	→ client	Notification marked read
memory.extracted	→ client	New memory extracted
memory.status	→ client	Memory approved/rejected
role.fallback	→ client	Role fallback triggered
workspace.updated	→ client	Workspace state changed
project.updated	→ client	Project metadata changed
extension.updated	→ client	Extension config changed
settings.updated	→ client	Global settings changed
user.updated	→ client	User profile changed
file.created	→ client	File uploaded or generated (§17b.4)
file.deleted	→ client	File removed

Direction: → client = server-to-client only, ← client = client-to-server only, ↔ both = bidirectional.

Page Routes (Non-API)

Server-rendered Go template surfaces. Not REST endpoints — these return HTML pages.

Route	Surface	Description
/login	Login	Standalone login/register page
/	Chat	Main chat interface
/chat/:chatID	Chat	Chat with specific channel loaded
/editor	Editor	Workspace file editor
/editor/:wsId	Editor	Editor with specific workspace
/notes	Notes	Notes interface
/notes/:noteId	Notes	Notes with specific note loaded
/admin	Admin	Platform administration
/admin/:section	Admin	Admin with specific section
/settings	Settings	User settings
/settings/:section	Settings	Settings with specific section

All page routes (except /login) require authentication via AuthOrRedirect middleware (reads sb_token cookie). Admin routes additionally require RequireAdminPage().

Dynamic surface routing for admin-installed extension surfaces is not yet implemented. The current five surfaces are hardcoded in Go route registration. Future: extension manifests declare surface routes, the page engine dynamically registers them with appropriate data loaders. See EXTENSIONS.md for the design direction.
