+# T05 Izveštaj: Reporter — pisanje izveštaja
+
+**Agent:** coder
+**Model:** Opus
+**Datum:** 2026-02-20
+
+---
+
+## Šta je urađeno
+
+Implementiran reporter u `code/internal/supervisor/`:
+
+### Kreirani fajlovi
+
+| Fajl | Opis |
+|------|------|
+| `reporter.go` | WriteReport, buildReport, formatDuration, truncateOutput |
+| `reporter_test.go` | 10 testova za sve funkcije |
+
+### Funkcije
+
+- **WriteReport** — generiše markdown izveštaj, kreira folder ako ne postoji
+- **buildReport** — sastavlja sadržaj sa headerom, verifikacijom, agent outputom
+- **formatDuration** — "Xm Ys" ili "Xs" format
+- **truncateOutput** — skraćuje na poslednjih N linija
+
+### Testovi — 10/10 PASS (reporter)
+
+```
+TestWriteReport_CreatesFile      PASS
+TestWriteReport_Content          PASS
+TestWriteReport_FailedStatus     PASS
+TestWriteReport_CreatesDirectory PASS
+TestTruncateOutput_Short         PASS
+TestTruncateOutput_Long          PASS
+TestTruncateOutput_Empty         PASS
+TestFormatDuration_Minutes       PASS
+TestFormatDuration_SecondsOnly   PASS
+TestFormatDuration_Zero          PASS
+```
+
+### Ukupno projekat: 50 testova, svi prolaze
+
+- `go vet ./...` — čist
+- `go build ./...` — prolazi

+# T05: Reporter — pisanje izveštaja
+
+**Kreirao:** planer
+**Datum:** 2026-02-20
+**Agent:** coder
+**Model:** Sonnet
+**Zavisi od:** T03 ✅, T04 ✅
+
+---
+
+## Opis
+
+Generiše markdown izveštaj posle izvršenog taska.
+Koristi RunResult iz T03 i VerifyResult iz T04.
+
+## Fajlovi za kreiranje
+
+```
+code/internal/supervisor/
+├── reporter.go      ← WriteReport()
+└── reporter_test.go
+```
+
+## Funkcije
+
+```go
+func WriteReport(
+    task Task,
+    run RunResult,
+    verify VerifyResult,
+    reportsDir string,
+) (string, error)  // vraća putanju do izveštaja
+```
+
+## Format izveštaja
+
+```markdown
+# T{XX}: Naslov
+
+**Datum:** 2026-02-20 10:15
+**Trajanje:** 8m 45s
+**Status:** ✅ Završen / ❌ Neuspešan
+**Tag:** v0.1.X
+
+## Verifikacija
+- ✅/❌ go build    (0.3s)
+- ✅/❌ go vet      (0.2s)
+- ✅/❌ go test     (12/12 testova, 2.1s)
+
+## Agent output
+(skraćen output Claude Code sesije, max 50 linija)
+
+## Commit
+- Hash: a1b2c3d
+- Branch: main
+```
+
+## Pravila
+
+- Fajl ime: `T{XX}-report.md` (npr. T01-report.md)
+- Ako reportsDir ne postoji — kreiraj
+- Output skrati na max 50 linija (poslednje linije, najrelevantnije)
+- Datum u formatu: YYYY-MM-DD HH:MM
+- Trajanje: Xm Ys ili Xs ako manje od minuta
+
+## Testovi
+
+- WriteReport sa mock podacima → fajl postoji, sadržaj tačan
+- Proveri format datuma, trajanja
+- Proveri da folder kreira ako ne postoji
+- Proveri skraćivanje outputa (>50 linija → samo poslednjih 50)
+- AllPassed=true → "✅ Završen"
+- AllPassed=false → "❌ Neuspešan"
+
+## Očekivani izlaz
+
+`TASKS/reports/T{XX}-report.md` se generiše sa tačnim sadržajem.
+`go test ./internal/supervisor/ -v` — svi testovi zeleni.
