+- **Agence d'intérim** (`InterimAgency` entity, table `interim_agencies`): optionnelle sur `EmployeeContractPeriod` quand nature = INTERIM. Pas de CRUD UI — gérée en BDD. API lecture seule `GET /interim_agencies`. Affichée "Intérim (NomAgence)" sur la liste employés et l'historique contrat.
 - Employee contract history: `employee_contract_periods`, resolved by `EmployeeContractResolver`
 - **Planning jours travaillés** (`EmployeeContractPeriod.workDaysHours` : JSON `{iso_day: minutes}`) : obligatoire pour tout contrat TIME **hors 35h/39h/INTERIM** (ex. 4h, 25h, 28h). Somme = `weeklyHours × 60`. Utilisé par `HolidayVirtualHoursResolver` (crédit férié) et `WorkedHoursCreditPolicy` (crédit absence) pour ne créditer que les jours effectivement travaillés. Validation : `EmployeeContractPeriodValidator::assertWorkDaysHours`.
