T16 Izveštaj: SSE auto-refresh dashboarda

Agent: coder Model: Opus Datum: 2026-02-20

---

Šta je urađeno

Dashboard se automatski ažurira kad se stanje taskova promeni putem SSE.

Novi fajlovi

Fajl	Opis
internal/server/events.go	EventBroker, polling (2s), hashTaskState, SSE handler

Izmenjeni fajlovi

Fajl	Izmena
internal/server/server.go	events field, GET /events ruta, startPolling u Run()
internal/server/render.go	renderBoardFragment() za SSE updates
internal/server/server_test.go	4 nova testa
web/templates/layout.html	initSSE(), isDragging flag, onStart handler
web/templates/partials/column.html	Uklonjen hx-trigger="every 5s" (zamenjeno SSE-om)

Kako radi

1. Server poluje TASKS/ svake 2s
2. Računa SHA-256 hash svih task ID:status parova
3. Ako se hash promenio → broadcast SSE event svim klijentima
4. Browser EventSource prima event → zameni board HTML
5. Tokom drag & drop — SSE update se ignoruje (isDragging flag)

Endpoint

Ruta	Opis
GET /events	SSE stream — event taskUpdate sa board HTML

Novi testovi — 4 PASS

TestSSE_EventsEndpoint       PASS  — proverava Content-Type text/event-stream
TestHashTaskState            PASS  — hash se menja kad se status menja, stabilan za isti set
TestSSE_BroadcastOnChange    PASS  — premesti fajl → broadcast event
TestSSE_NoBroadcastWithoutChange PASS — bez promene → bez eventa
