+### F-14: Job-queue inzicht en beheer (`/jobs`)
+
+**Prioriteit:** v1 — Operationele controle
+**Persona:** Lars
+
+**Omschrijving:**
+De `/jobs`-pagina geeft een overzicht van alle `ClaudeJob`-records voor het actieve product. Vanuit de `JobDetailPane` kan de gebruiker een mislukte, geannuleerde of overgeslagen job opnieuw in de wachtrij zetten.
+
+**Acceptatiecriteria:**
+
+#### Mislukte job opnieuw starten
+
+- [ ] Een `ClaudeJob` in status `FAILED`, `CANCELLED` of `SKIPPED` toont een "Opnieuw starten"-knop in de `JobDetailPane`.
+- [ ] De knop reset de bestaande job (geen nieuwe job aanmaken): `status → QUEUED`, `retry_count + 1`, alle run-velden gecleared.
+- [ ] Bij `SPRINT_IMPLEMENTATION`-jobs worden alle bijbehorende `SprintTaskExecution`-rows in dezelfde transactie teruggezet naar `PENDING`.
+- [ ] Tijdens de server-action is de knop disabled (loading-state). De UI updatet via SSE zonder handmatige refresh.
+- [ ] Demo-sessies zien een `DemoTooltip` op de knop en kunnen niet restarten (drie-laagse policy: knop disabled + server action `session.isDemo`-check + HTTP 403).
+
+**Randgevallen:**
+- Job is ondertussen al door een andere actie opnieuw gestart (race condition) → server-action controleert de huidige status vóór de update; als de status niet meer `FAILED/CANCELLED/SKIPPED` is, retourneert de action een foutmelding.
+- Demo-token probeert via directe API-aanroep te restarten → 403 Forbidden.
