+# Lane L12 – Zeiterfassung (`lane/zeiterfassung`)
+
+Stand: 2026-09-15 · Basis `d3bc7f2` (`feature/craftvia-mvp`, L1–L11 integriert)
+
+Ziel: Zeiterfassung der Monteure deutlich einfacher – laufende Uhr überall, „Für heute beenden“, Auto-Wechsel zwischen Aufträgen, Zeit nachtragen + Tagesübersicht. **Entscheidung des Nutzers:** Monteure tragen eigene Zeiten nach / schlagen Korrekturen vor – mit Freigabe durch Teamleiter (eigene Teams) oder Backoffice; bis zur Freigabe zählen sie nicht für Bericht und Abrechnung.
+
+## 1. Umfang
+
+| Punkt | Umsetzung |
+|---|---|
+| Datenmodell | Migration `20260915120000_zeiterfassung_freigabe` (nur additive Spalten, keine neue Tabelle → keine RLS-/TENANT_MODELS-Änderung): `TimeEntry.source` (`tracked`/`manual`), `approvalStatus` (`approved`/`pending`/`rejected`, Default approved → Bestand unverändert), `approvedById` (entscheidende Person, auch bei Ablehnung), `approvedAt`, `rejectionReason`, `pendingChange` (Json: vorgeschlagene Korrektur `{startedAt, endedAt, type, reason, requestedAt, requestedById}`), `note`; Index `(tenant_id, approval_status)`. `WorkSession.manual` (Boolean). Begründung eines Nachtrags liegt in `correctionReason`. PII: `TimeEntry.approvedById` in `pii-fields.ts`. |
+| Manuelle Session (Begründung) | Nachträge hängen an einer „manuellen“ Session je User + Auftrag + lokalem Tag (`manual = true`, Status `ended`, Start/Ende = min/max der Einträge). So bleiben alle bestehenden Lesepfade (Auftrag → Sessions → Einträge: Bericht, Zeiten-Tab, Bundle, Lotse, Abschluss-Blocker) ohne Sonderfälle korrekt; `ended` löst keine Blocker/aktive-Session-Logik aus. Eine eigene Tabelle hätte jeden Lesepfad verdoppelt. |
+| Rechte | `field:record_own_time` → technician, team-lead; `time:approve` → team-lead, backoffice, tenant-admin (Katalog). `scripts/sync-role-permissions.ts` zieht bestehende Mandanten nach (lokal ausgeführt: +12 Zuordnungen). |
+| Services `services/field/time-entries.ts` | `addManualTimeEntry` (Scope, Status nachtragbar = Feldstatus + `in_review`, ≤ 7 Tage zurück ab Tagesbeginn Mandanten-TZ, nicht Zukunft, Ende > Beginn, ≤ 16 h, keine Überlappung mit eigenen nicht abgelehnten Einträgen → `invalid`/`overlap`; eigener Eintrag → pending + Event; `forUserId` mit `field:correct_time` nur für aktive Mitglieder geführter Teams bzw. Backoffice → approved; idempotent über `clientId`), `proposeTimeCorrection` (nur eigener, abgeschlossener Eintrag ≤ 7 Tage; approved bleibt gültig, `pendingChange`; bei noch offenem Nachtrag werden die offenen Werte direkt geändert), `approveTimeEntry`/`approveTimeEntries`/`rejectTimeEntry` (`time:approve`, Team-Scope, nie eigene Einträge, Überlappungsprüfung bei Freigabe, Korrektur → Werte übernommen + `corrected`), `listPendingTimeEntries`, `countPendingTimeEntries`, `pendingTimeOfOrder`, `getMyTimeOverview`, `listRecordableOrders`, `listRecordableUsers`. Alle Mehrschritt-Writes in `inTransaction`, Audit before/after, Events nach Commit. |
+| Team-Scope | Backoffice (`work_order:read_all`) → alle; Teamleiter → Einträge auf Aufträgen seiner geführten aktiven Teams, Aufträge mit `teamLeadUserId = er` oder von aktiven Mitgliedern seiner Teams. Außerhalb → `not_found`. |
+| Sessions `services/field/sessions.ts` | Alle Session-Mutationen jetzt in `inTransaction`. **Auto-Wechsel:** `startSession`/`resumeSession` werfen `conflict other_session_running {workOrderId, number, title}`, wenn der Nutzer auf einem anderen Auftrag eine laufende/Anfahrts-Session hat; mit `switchFromOther: true` wird diese in derselben Transaktion pausiert (Pause-Segment, Auftrag `paused`, falls sonst niemand arbeitet). `stopForToday` (Session beendet, Auftrag bleibt offen → `paused` über `transitionWorkOrder`, kein Abschluss). `switchSegment` (`work`/`return_travel`/`material_procurement`). `getMyActiveSession` (laufende vor pausierter, Segmentstart, aufsummierte Dauer ohne Pausen). `correctTimeEntry`: eigene Einträge → `forbidden own_entry`, räumt offene Vorschläge ab. |
+| Zählen nur freigegeben | `reports/build-content.ts` (Summen nur approved, neues optionales Feld `time.pendingMinutes` im Snapshot), Backoffice Zeiten-Tab (`workMinutes` approved, `pendingMinutes`), mobile Auftragsdetail/Zeiten, Lotse-Vollständigkeit, Meine Zeiten. **Abrechnungsfreigabe** (`completion.ts#transitionBlockers`) → `blocked` mit `missing_field: pending_time_entries`, solange Nachträge oder Korrekturvorschläge offen sind. Bericht einreichen warnt nur (Hinweis auf `/m/orders/[id]/report`). |
+| Sync/Offline | Ops `session.stop_day`, `session.segment`, `time.add_manual`, `time.propose_correction` (Envelope + Zod in `lib/sync/ops.ts`, Dispatch in `sync/apply.ts`), `session.start`/`session.resume` mit `switchFromOther?`. Outbox ohne Sonderlogik; `VERSION_CHANGING_OPS` um stop_day/segment ergänzt (verkettete baseVersion). Optimistische Ansicht (`bundle-core.ts`): stop_day → Uhr aus, Auftrag pausiert; add_manual → `local.manualTimes` mit pending. Abgelehnte Ops im Klartext auf `/m/sync` (`offline.problem.timeOverlap`, `timeWindow`, `otherSession`). Konfliktmeldung des Auto-Wechsels trägt die Auftragsdaten (`other_session_running:{…}`). |
+| Events/Benachrichtigungen | `time.approval_requested` → Teamleiter des Auftrags-Teams bzw. der Teams des Monteurs (mit `time:approve`, ohne Antragsteller), sonst Backoffice (`read_all` + `time:approve`); In-App + E-Mail (über Einstellungen abbestellbar). `time.approved`/`time.rejected` → Monteur, nur In-App, Ablehnungsgrund im Text. Links: Backoffice `/work-orders/time-approvals`, Teamleiter `/m/approvals`, Monteur `/m/time`. |
+
+## 2. Screens / Routen
+
+| Route | Inhalt |
+|---|---|
+| Mobile-Shell (alle `/m`-Seiten) | **Laufende-Uhr-Leiste** über der Bottom-Nav: Status (Text + Punkt), „A-00042 · Titel · 1:23 h“ (Sekunden-Tick), Tipp → Auftrag, Pause/Weiter, „Für heute beenden“ (zweistufig), Link „Meine Zeiten“; offline aus lokalem Zustand (ohne Dauer). Badge-Zähler offener Freigaben am „Profil“. |
+| `/m`, `/m/orders` | je Karte direkter Button Arbeit starten / Pause / Weiter; laufende Karte mit breiter Statuskante + Text „Zeit läuft“/„Pausiert“. |
+| Auto-Wechsel | Bottom-Sheet „A-00041 läuft noch. Pausieren und A-00042 starten?“ [Wechseln] [Abbrechen] – aus Karte, Auftragsdetail und Uhr-Leiste. |
+| `/m/orders/[id]` | laufend: primär „Pause“, sekundär „Für heute beenden“ (mit Hinweis), Textlink „Auftrag abschließen …“ (bestehender Flow mit Bestätigung/Blockern); kleinere Segment-Aktionen „Rückfahrt starten“, „Material holen“, „Zurück zur Arbeit“. |
+| `/m/orders/[id]/time` | Badges manuell/zur Freigabe/abgelehnt/Korrektur beantragt, freigegebene + offene Summe, eigene Einträge „Korrektur vorschlagen“, fremde (Teamleiter) Direktkorrektur, „Zeit nachtragen“ für den Auftrag. |
+| `/m/time` | **Meine Zeiten:** Tages-Chips (Heute, Gestern, weitere 6 Tage), Summen freigegeben/offen, Einträge je Auftrag mit Art, von–bis, Dauer, Badges, „Korrektur vorschlagen“, nicht übertragene lokale Nachträge. |
+| `/m/time/new` | **Zeit nachtragen:** Auftrag (letzte 7 Tage/laufend), optional „Für“ (Teammitglied, nur `field:correct_time`), Art-Chips, Datum, Von–Bis oder Dauer (15/30/60 min), Begründung Pflicht mit Vorschlägen, Notiz, Hinweis „Wird nach Freigabe durch Teamleiter oder Büro gezählt“. |
+| `/m/approvals` | Teamleiter (`time:approve`): offene Nachträge/Korrekturen (alt → neu), große Buttons Freigeben / Ablehnen mit Grund. |
+| `/work-orders/time-approvals` | Backoffice: Tabelle Mitarbeiter, Auftrag, Datum, von–bis (alt → neu), Dauer, Art, Begründung; Einzel- und Sammelfreigabe, Ablehnen mit Grund. Navigation „Zeiten zur Freigabe“, Dashboard-Kachel. |
+| `/work-orders/[id]?tab=times` | Summe freigegeben + offen, Badges, Freigabe/Ablehnung inline. |

+
+## 4. Tests
+
+- `scripts/test-zeiterfassung-service.ts` – **78 Prüfungen**: Validierung (Überlappung → `invalid overlap`, > 7 Tage, Zukunft, > 16 h, Ende vor Beginn, ohne Grund, ohne Zuweisung → not_found, Backoffice ohne Recht, Monteur für Kollegen), manuelle Session, Events (Teamleiter statt Monteur/Backoffice; eigener Teamleiter-Nachtrag → Backoffice) + Audit, pending zählt nicht (Tagesbericht, Zeiten-Tab, Meine Zeiten), Freigabe-Rollen (Monteur nie, Teamleiter nicht eigene, fremder Teamleiter not_found, Backoffice alle, Sammelfreigabe, Direktkorrektur eigener Einträge forbidden), Listen/Badge/Dashboard, Freigabe → zählt + `time.approved`, Ablehnung mit Grund + `time.rejected` (Text, Link) + abgelehnter Zeitraum frei, Korrekturvorschlag (alter Wert bis Freigabe, danach neu + corrected; abgelehnter Vorschlag lässt Eintrag gültig), Direktanlage für Teammitglied (approved) bzw. Nicht-Mitglied forbidden, Abrechnungsfreigabe blocked `pending_time_entries` und nach Freigabe möglich, „Für heute beenden“ (Session ended, Auftrag paused, kein Blocker), Auto-Wechsel (conflict mit Nummer, nichts angelegt, fehlgeschlagener Wechsel lässt andere Session laufen, mit Flag pausiert + genau eine laufende Uhr, Weiter ebenfalls geprüft), Segmente + `getMyActiveSession`, Mandantentrennung (B kann weder freigeben, ablehnen, sehen, nachtragen noch vorschlagen).
+- `scripts/test-zeiterfassung-sync.ts` – **29 Prüfungen**: Payload-Schemas, 4 neue Ops in einem Batch applied (idMap, entityVersion), gleiche clientOpIds → duplicate ohne Doppelanlage, Event über Sync, Überlappung → rejected mit Klartext-Schlüssel (`timeOverlap`/`timeWindow`), Korrekturvorschlag über Sync, Auto-Wechsel-Konflikt mit Auftragsnummer (`otherSession`) und Wechsel mit Flag, verkettete baseVersion, optimistische Ansicht (stop_day, add_manual pending), Mandant B / Monteur ohne Zuweisung → not_found.
+- Bestehend angepasst: `test-security-roles.ts` (Proben `field:record_own_time`, `time:approve`).
+- Gate/RLS: siehe §7.
+
+**HTTP-Smoke** (Dev-Server :3113, `scripts/smoke-auth.ts`, Demo-Seed, Rechte per `sync-role-permissions` nachgezogen): **105/105 grün** – neu: Backoffice `/work-orders/time-approvals`, Dashboard-Kachel; Teamleiter `/m/time`, `/m/approvals`, Profil-Link; Monteur Uhr-Leiste auf `/m` („Laufende Zeiterfassung“, „Für heute beenden“), `/m/time` (heute/gestern), `/m/time/new`, `/m/approvals` ohne Recht → Hinweis, Zeiten-Seite des Auftrags. Visuelle Browserprüfung nicht durchgeführt (Login würde Passworteingabe/Token-Einschleusen durch den Agenten erfordern).
+
+## 5. Bekannte Lücken / Hinweise
+
+1. **Demo-/Bestandsdaten mit zwei laufenden Sessions** eines Nutzers (vor L12 möglich, z. B. Seed: `monteur@` auf A-00009 und N-00001) bleiben bestehen; die Uhr-Leiste zeigt die neueste, der nächste Start/Weiter erzwingt den Wechsel.
+2. **Backoffice hat kein `field:correct_time`** (Rollenfilter schließt `field:*` aus): Direktanlage für Mitarbeiter mobil nur für Teamleiter/Mandantenadmin; Backoffice gibt frei/lehnt ab. Falls gewünscht, Recht im Katalog ergänzen.
+3. **Offline-Uhr** kennt keine Dauer (Bundle ohne Einträge) – offline nur Auftrag + Status. Auto-Wechsel-Dialog erscheint offline erst beim Sync (Op wird dann auf `/m/sync` im Klartext abgelehnt); der optimistische Wechsel pausiert die andere Auftragsansicht lokal nicht.
+4. **Zeitzone**: Formular nutzt die Gerätezeit, Server prüft das 7-Tage-Fenster in der Mandanten-Zeitzone (`TenantSettings.timezone`).
+5. **Transaktionen + Events**: `transitionWorkOrder` emittiert Events innerhalb der Session-Transaktion (bestehendes Verhalten, ABNAHME §5); pg meldet dabei eine Deprecation-Warnung für parallele Queries auf dem Transaktions-Client (harmlos).
+6. **Nachträge auf abgerechneten/stornierten Aufträgen** nicht möglich (`work_order_status`); nach Abrechnungsfreigabe erfasste Korrekturen gibt es damit nicht.
+7. Freigabefrist/Eskalation und Lohn-Export nicht umgesetzt (ABNAHME §4 „zu klären“).
+
+## 6. Migration
+
+`20260915120000_zeiterfassung_freigabe` – rein additiv (2 Enums, 7 Spalten `time_entries`, 1 Spalte `work_sessions`, 1 Index). Bestehende Zeilen: `tracked` + `approved` → unverändertes Verhalten. Deploy: `prisma migrate deploy` + `scripts/sync-role-permissions.ts` (Nutzer neu anmelden).
+
+## 7. Gate
+
+`npm run gate` **grün**: prisma generate, tsc, lint (0 Fehler, 3 bestehende Warnungen außerhalb L12), build inkl. Modul-Guard-Check (33 Action-Dateien), **67/67 Testskripte** (davon neu `test-zeiterfassung-service` 78 ✓, `test-zeiterfassung-sync` 29 ✓).
+
+Im ersten Gate-Lauf schlugen `test-notdienst-flow`/`test-notdienst-review` fehl: Die Notdienst-Erfassung startet eine Session, während der Monteur noch auf einem anderen Auftrag arbeitet → neue Regel „eine laufende Uhr“ lieferte `other_session_running`. Behoben in `services/emergency/create.ts` (`switchFromOther: true` – ein Notdiensteinsatz pausiert die laufende Uhr automatisch).
+
+**RLS-Lauf** `RLS_ENFORCED=true npm run test` (RLS_DATABASE_URL auf die Lane-DB `craftvia_zeiterfassung`): **67/67 Testskripte grün** – alle Session-/Freigabe-Writes laufen über `inTransaction` und sind damit auch unter scharfer RLS atomar.
