+# T19 Izveštaj: Dugme "Pusti" — pokreni agenta u čistoj sesiji
+
+**Agent:** coder
+**Model:** Opus
+**Datum:** 2026-02-20
+
+---
+
+## Šta je urađeno
+
+Dodat "Pusti ▶" dugme na task karticama i POST /task/{id}/run endpoint.
+
+### Novi/izmenjeni fajlovi
+
+| Fajl | Izmena |
+|------|--------|
+| `internal/server/server.go` | POST /task/:id/run ruta, handleRunTask handler |
+| `internal/server/render.go` | taskCardData wrapper sa CanRun, canRunTask(), doneSet logika |
+| `internal/server/console.go` | timeNow() helper |
+| `internal/server/server_test.go` | 6 novih testova |
+| `web/templates/partials/task-card.html` | "Pusti ▶" dugme sa hx-post |
+| `web/templates/layout.html` | htmx:afterRequest handler za run response + toast |
+| `web/static/style.css` | btn-run stil |
+
+### Endpoint
+
+| Ruta | Opis |
+|------|------|
+| `POST /task/{id}/run` | Pokreni task u prvoj slobodnoj sesiji |
+
+### Logika
+
+1. Nađi task, proveri status
+2. backlog → proveri deps (sve u done?), premesti u ready
+3. ready → nađi slobodnu sesiju (1 ili 2)
+4. Nema slobodne → 409 "obe sesije zauzete"
+5. Pokreni `claude --dangerously-skip-permissions -p "..."`
+6. Output ide u konzolu sesije
+7. Toast + board refresh
+
+### Dugme se prikazuje za
+
+- backlog/ taskove čije su zavisnosti u done/
+- ready/ taskove
+- review/ taskove
+
+### Ne prikazuje se za
+
+- active/ (već rade)
+- done/ (završeni)
+- backlog/ sa neispunjenim zavisnostima
+
+### Novi testovi — 6 PASS
+
+```
+TestRunTask_Ready            PASS
+TestRunTask_BacklogWithDeps  PASS
+TestRunTask_AlreadyDone      PASS
+TestRunTask_NotFound         PASS
+TestRunTask_BothSessionsBusy PASS
+TestDashboardHTML_HasRunButton PASS
+```

+# T19: Dugme "Pusti" na svakom tasku — pokreni agenta u čistoj sesiji
+
+**Kreirao:** planer
+**Datum:** 2026-02-20
+**Agent:** coder
+**Model:** Sonnet
+**Zavisi od:** T14 ✅
+
+---
+
+## Opis
+
+Svaki task u backlog/ready koloni ima dugme "Pusti".
+Klik → server pokrene NOVI Claude Code proces sa ČISTIM kontekstom.
+Agent zna SAMO: CLAUDE.md + svoj task fajl. Ništa drugo.
+
+## KLJUČNO — čist kontekst
+
+Svaki task se pokreće u zasebnom `claude` procesu:
+```bash
+claude --dangerously-skip-permissions -p "Pročitaj CLAUDE.md i radi task TASKS/ready/T{XX}.md"
+```
+
+Agent NEMA kontekst iz prethodnih taskova.
+Agent NEMA istoriju razgovora.
+Agent čita CLAUDE.md → razume pravila → čita task → radi.
+
+## Workflow sa dugmetom
+
+1. Operater vidi task karticu na boardu
+2. Klik "Pusti ▶" na kartici
+3. Ako je task u backlog/ → server ga premesti u ready/ pa pokrene
+4. Ako je task u ready/ → server ga odmah pokrene
+5. Server pokrene novi `claude` proces (čist kontekst)
+6. Output ide u konzolu (sesija 1 ili 2, prva slobodna)
+7. Kartica se pomeri u Active kolonu (automatski)
+
+## Izgled kartice
+
+```

+
+Dugme se prikazuje SAMO za:
+- backlog/ taskove čije su zavisnosti ispunjene (sve u done/)
+- ready/ taskove
+- review/ taskove koji imaju odgovor (## Odgovori nije prazan)
+
+Dugme se NE prikazuje za:
+- active/ taskove (već rade)
+- done/ taskove (završeni)
+- backlog/ taskove čije zavisnosti nisu ispunjene
+
+## Endpointi
+
+```
+POST /task/{id}/run              → pokreni task u čistoj sesiji
+  Response: {"session": 1, "status": "started"}
+
+POST /task/{id}/run?session=2    → pokreni u konkretnoj sesiji
+```
+
+## Server logika za /task/{id}/run
+
+```
+1. Nađi task (ScanTasks)
+2. Proveri da zavisnosti su u done/
+3. Ako je u backlog/ → premesti u ready/
+4. Nađi slobodnu sesiju (1 ili 2)
+5. Ako nema slobodne → vrati 409 "Obe sesije zauzete"
+6. Pokreni: claude --dangerously-skip-permissions -p "..."
+7. Poveži output sa konzolom sesije
+8. Vrati session ID
+9. Dashboard se ažurira (SSE ili HTMX swap)
+```
+
+## Prompt za agenta
+
+```
+Pročitaj CLAUDE.md u root-u projekta.
+Tvoj task: TASKS/ready/T{XX}.md
+Pročitaj task fajl i uradi šta piše.
+Prati pravila iz CLAUDE.md — build, test, commit, tag, izveštaj.
+```
+
+Kratak, čist. Agent sam čita CLAUDE.md i task.
+
+## Testovi
+
+- POST /task/T15/run → pokrene proces, vrati session ID
+- Task premešten u active/ posle pokretanja
+- Druga sesija: POST /task/T16/run → pokrene u sesiji 2
+- Obe sesije zauzete: POST /task/T17/run → 409
+- Task sa neispunjenim zavisnostima → 400
+- Task koji je već active → 400
