🔴 readLoop race: replace WriteControl close with ctx-done goroutine that closes conn
🔴 duplicate event handlers: clear handlers map before re-registering on reconnect
🔴 sync.go CurrentTask abuse: add DisplayName field to UpdateAgentRequest, use it
🔴 sync.go newRole dead code: add Role field to UpdateAgentRequest, use it
🔴 events.go handlePresence DB/SSE inconsistency: pass LastActivityAt in update, don't mutate after DB
🔴 events.go handleAgentConfig DB/SSE inconsistency: use DisplayName/Role fields in update
🟠 Send() nil-conn panic: check conn != nil before WriteJSON
🟠 readLoop prompt ctx cancellation: fixed by item #1
🟠 backoff never resets: reset to initialBackoff after successful connectAndRun
🟠 MarkWSReady double-close race: use sync.Once in Client
Extra json:"-" dead fields: removed from sessionChangedPayload, presencePayload, agentConfigPayload
UpdateAgentRequest: added DisplayName, Role, LastActivityAt fields
- Create gateway/sync.go with initialSync method on WSClient
- Fetch agents via agents.list RPC, persist to AgentRepo
- Fetch sessions via sessions.list RPC, map status to AgentStatus
- Merge session state (status, sessionKey, tokens) into AgentCardData
- Broadcast merged fleet as fleet.update via SSE broker
- Trigger initialSync after hello-ok handshake
- Re-sync automatically on reconnect (connectAndRun calls initialSync)
- Handle unknown gateway fields gracefully via typed extraction
