+# T14 Izveštaj: Dashboard — konzola za komunikaciju sa agentom
+
+**Agent:** coder
+**Model:** Opus
+**Datum:** 2026-02-20

+
+## Šta je urađeno
+
+Dodata konzola u dashboard — terminal interfejs za pokretanje Claude Code iz browsera.
+
+### Novi fajlovi
+
+| Fajl | Opis |
+|------|------|

+| `web/templates/console.html` | Template sa dva panela, input, output, toolbar |
+
+### Izmenjeni fajlovi
+
+| Fajl | Izmena |
+|------|--------|
+| `internal/server/server.go` | Console field u Server, 6 novih ruta, consoleManager init |

+| `web/static/style.css` | Console stilovi (paneli, output, input, status) |
+
+### Endpointi
+
+| Ruta | Opis |
+|------|------|
+| `GET /console` | Konzola HTML stranica |

+
+### Features
+
+- 2 paralelne sesije (svaka = zaseban Claude Code proces)
+- SSE streaming outputa u realnom vremenu
+- Komanda → Enter ili klik dugme
+- Kill dugme za prekid procesa
+- Istorija komandi (↑/↓ strelice, max 50 po sesiji)
+- Second panel toggle (+/- Sesija 2)
+- Input disabled dok komanda radi
+- Status badge (idle/running)
+- Scroll to bottom na novi output
+- `claude --dangerously-skip-permissions -p` za izvršavanje
+
+### Novi testovi — 7 PASS
+
+```
+TestConsolePage              PASS
+TestConsoleSessions          PASS
+TestConsoleExec_InvalidSession PASS
+TestConsoleExec_ValidRequest PASS
+TestConsoleKill_IdleSession  PASS

+TestConsoleHistory_AfterExec PASS
+```
+
+### Ukupno projekat: 116 testova, svi prolaze
+
+- `go vet ./...` — čist
+- `go build ./...` — prolazi

+# T14: Dashboard — konzola za komunikaciju sa agentom
+
+**Kreirao:** planer
+**Datum:** 2026-02-20
+**Agent:** coder
+**Model:** Sonnet
+**Zavisi od:** T12
+
+---
+
+## Opis
+
+Terminal/konzola unutar dashboarda. Operater šalje komande mastermindu,
+vidi output. Kao chat sa Claude Code-om ali iz browsera.
+
+## Kako radi
+
+1. Tab "Konzola" na dashboardu
+2. Dva panela — mogućnost pokretanja 2 paralelne sesije
+3. Svaka sesija = zaseban Claude Code proces (`claude` CLI)
+4. Operater šalje komandu → ENTER
+5. Server pokrene Claude Code sa tom komandom
+6. Output se prikazuje u realnom vremenu (SSE stream)
+7. Kad završi — prompt se vraća
+
+## Izgled
+
+```
+┌──────────────────────────┬──────────────────────────┐
+│ 🔧 Sesija 1              │ 🔧 Sesija 2              │
+├──────────────────────────┼──────────────────────────┤
+│ > radi T13               │ > radi T14               │
+│ ✅ T13 pokrenut...       │ ✅ T14 pokrenut...       │
+│ [streaming output]       │ [streaming output]       │
+│ ...                      │ ...                      │
+│                          │                          │
+│ ┌────────────────────┐   │ ┌────────────────────┐   │
+│ │ Komanda...    [⏎] │   │ │ Komanda...    [⏎] │   │
+│ └────────────────────┘   │ └────────────────────┘   │
+└──────────────────────────┴──────────────────────────┘
+```
+
+Operater može koristiti 1 ili 2 panela. Drugi panel se otvara dugmetom [+].
+
+## Endpointi
+
+```
+POST /console/exec              → pokreni komandu (body: {"cmd": "...", "session": 1|2})
+GET  /console/stream/{id}       → SSE stream outputa
+GET  /console/history/{session}  → istorija komandi za sesiju
+POST /console/kill/{session}     → prekini proces u sesiji
+GET  /console/sessions           → status obe sesije (idle/running)
+```
+
+## Podržane komande
+
+Konzola poziva kaos-supervisor CLI:
+
+| Komanda | Šta radi |
+|---------|----------|
+| `status` | Prikaži status svih taskova |
+| `next` | Šta je sledeće za rad |
+| `verify` | Pokreni verifikaciju |
+| `history` | Prikaži izvršene taskove |
+| `radi [TASK_ID]` | Pokreni task |
+
+Nepoznata komanda → prosleđuje se Claude Code-u kao free-form prompt.
+
+## SSE streaming
+
+```javascript
+const source = new EventSource('/console/stream/' + execId);
+source.onmessage = function(e) {
+    document.getElementById('console-output').innerHTML += e.data + '\n';
+};
+source.addEventListener('done', function(e) {
+    source.close();
+    // vrati prompt
+});
+```
+
+## Pravila
+
+- Max 2 paralelne sesije (svaka = zaseban `claude` proces)
+- Sesije ne smeju raditi na istom tasku
+- Server proverava: ako je task već active/ u drugoj sesiji → odbij
+- Timeout: KAOS_TIMEOUT iz .env (po sesiji)
+- Output se čuva u memoriji (poslednje 50 komandi po sesiji)
+- Scroll to bottom na novi output
+- Ctrl+C → prekini trenutnu komandu (POST /console/kill/{session})
+- Istorija komandi: ↑/↓ strelice (po sesiji)
+- Claude Code se pokreće: `claude --dangerously-skip-permissions`
+
+## Testovi
+
+- POST /console/exec {"cmd": "status", "session": 1} → 200 + exec ID
+- GET /console/stream/{id} → SSE stream
+- Dve sesije paralelno → obe rade
+- Isti task u obe sesije → druga odbijena
+- POST /console/kill/1 → prekine sesiju 1
+- GET /console/sessions → status obe sesije
+- GET /console/history/1 → lista komandi sesije 1
