fix(rtt) : skip non-contracted days in overtime 25% threshold

computeWeeklyOvertime25StartMinutes used a ternary that fell back to 35h
when a day had no active contract. Once periodFrom was uncapped (so the
RTT week iterates the full exercise), pre-hire days were silently
contributing 7h each to the weekly threshold, erasing the 25% overtime
for the employee's first partial week.

Dylan CHABOISSON week 12 (Mar 19 hire, worked Thu 9h + Fri 9h30 +
Sat 3h30 = 22h): threshold was 36h (incorrect), now back to 15h (Thu 8h
+ Fri 7h) so the 7h above threshold + 1h45 bonus are correctly credited.

 - **FORFAIT — jours de présence et N-1** : les congés posés et imputés sur le stock N-1 ne décrémentent **pas** les jours de présence affichés (`presenceDaysByMonth` et `presenceDaysToToday`). Implémenté dans `EmployeeLeaveSummaryProvider::computePresenceDaysByMonth` via un budget N-1 (= `previousYearTakenDays`) consommé chronologiquement avant comptage des absences.

+- **Sélecteur d'année** en pied de calendrier (zone scrollable, à gauche). Plage : de l'exercice courant jusqu'à `max(floor_contrat, floor_data_start_date)` — `floor_contrat` = premier exercice avec contrat ouvert (`employee.contractHistory[].startDate`) ; `floor_data_start_date` = exercice contenant `RTT_START_DATE` (env, ex. `2026-02-23` → exercice 2026). Le double plancher empêche de remonter avant la mise en service du logiciel. Format : `2026` pour FORFAIT, `Juin 2025 → Mai 2026` sinon.

Backend : filtre `?year=YYYY` validé 2000-2100, et `EmployeeLeaveSummary` expose `dataStartDate` (env `RTT_START_DATE`, injecté via `services.yaml`).

+# Vue contrat — sélecteur de phase
+
+## Objectif
+
+Permettre à la RH de consulter les onglets Congés et RTT d'un employé selon une phase de contrat passée (ex. un 39h CDI avant un switch FORFAIT, ou un CDD clôturé avec solde de tout compte) sans changer le comportement par défaut sur la phase courante.
+
+## Concept de "phase"
+
+Une **phase** = groupe d'`EmployeeContractPeriod` consécutifs (triés par `startDate`) partageant la signature `(contract.type, weeklyHours, isDriver)`. Le service `EmployeeContractPhaseResolver` (`src/Service/Contracts/EmployeeContractPhaseResolver.php`) calcule ces phases à la volée depuis `Employee::getContractPeriods()`.
+
+Une transition de signature (35h → 39h, 39h → FORFAIT, driver false→true, weeklyHours 28→30, etc.) ouvre une nouvelle phase. Un type différent entre deux périodes de même signature empêche leur fusion (39h → INTERIM → 39h = 3 phases).
+
+## Filtrage par `RTT_START_DATE`
+
+Les phases dont la date de fin est strictement antérieure à `RTT_START_DATE` (env, date de mise en service du logiciel) sont **masquées** du picker. Aucune donnée logiciel (heures, absences) n'existe avant cette date, donc consulter une phase entièrement antérieure n'a pas de sens fonctionnel.
+
+Exemple : un employé sous 35h CDI de 2014 à 2025-10-31 puis 39h CDI depuis 2025-11-01, avec `RTT_START_DATE=2026-02-23` :
+- Phase 35h (2014 → 2025-10-31) : entièrement avant → masquée
+- Phase 39h (depuis 2025-11-01) : chevauche → visible
+- Résultat : 1 seule phase visible → picker caché (seuil ≥ 2 phases)
+
+Une phase dont la date de fin est égale à `RTT_START_DATE` est conservée (inégalité `>=`, non stricte).
+
+`EmployeeContractPhaseResolver` reçoit `RTT_START_DATE` via DI (`services.yaml`). L'entité `Employee::getContractPhases()` lit la valeur depuis `$_SERVER`/`$_ENV` directement (l'entité n'a pas d'injection) et passe la chaîne au constructeur du resolver.
+
+## Picker UI
+
+- Position : en haut de la fiche employé, sous le nom et au-dessus des onglets.
+- Libellé : `Vue contrat`.
+- Caché si l'employé n'a qu'une seule phase.
+- Sélection non persistée — chaque ouverture de fiche démarre sur la phase courante.
+
+## Bandeau d'information
+
+Affiché quand le picker est sur une phase passée. Indique que le mode lecture est partiel — les paiements de solde restent possibles, l'édition d'absences et des stocks de report est désactivée.
+
+## Effet sur les onglets
+
+| Onglet | Effet |
+|---|---|
+| Congés | Recharge avec les règles de la phase. Période Juin→Mai pour non-forfait, Jan→Déc pour FORFAIT. Exercices bornés à la phase. |
+| RTT | Visible ssi `phase.contractType !== FORFAIT`. Le tableau affiche **toujours toutes les semaines de l'exercice** (Juin→Mai). Pour une phase clôturée, `periodTo` et `limitDate` sont capés à `phase.endDate` (les semaines après la fin de phase contribuent 0 au cumul). `periodFrom` n'est pas capé : les semaines avant l'embauche ou avant le début d'une phase passée apparaissent à 0 (pas de contrat → pas de référence → 0 minute). |
+| Heures, Frais, Formation, Contrat, Calendrier | Non impactés. |
+
+## Paiements de solde sur phase passée
+
+- **RTT** : `+ Payer les RTT` activé sur le **dernier exercice de la phase** uniquement (l'exercice contenant `phase.endDate`). Les exercices antérieurs restent en lecture seule.
+- **CP** : utiliser le mécanisme existant `EmployeeContractPeriod.paidLeaveSettledClosureDate` pour solder. Pas de nouveau channel.
+
+## Transition d'exercice
+
+Quand un exercice chevauche deux phases, les bornes sont capées différemment selon le type de phase consultée :
+
+### Phase FORFAIT (passée ou courante)
+
+Le cumul 218 jours est **par année civile**. Toute consultation FORFAIT cape :
+- `from` à `max(phase.startDate, 1er janvier de l'année)`
+- `to` à `min(phase.endDate, 31 décembre de l'année)`
+
+Ex. switch 39h → FORFAIT au 01/05/2026, vue FORFAIT année 2026 → période = [01/05/2026, 31/12/2026].
+
+### Phase non-forfait (35h / 39h / CUSTOM / INTERIM)
+
+L'exercice CP est **annuel** (Juin N-1 → Mai N) et continu à travers les changements d'heures contractuelles dans le même régime non-forfait. La cap **n'applique pas** sur `from` :
+- `from` reste à 1er juin de l'année (le contrat-entry-date est géré par `resolveEffectivePeriodStart` pour les nouveaux embauchés)
+- `to` est borné à `phase.endDate` uniquement quand on consulte une **phase passée**
+
+Ex. employé 35h jusqu'au 31/10/2025 puis 39h depuis le 01/11/2025 :
+- Vue 39h (courante) sur exercice 2026 → période = [01/06/2025, 31/05/2026]. Acquis CP = exercice complet (~27.5 jours à fin avril).
+- Vue 35h (passée) sur exercice 2026 → période = [01/06/2025, 31/10/2025]. Acquis CP = 5 mois de l'exercice.
+
+**Important** : c'est intentionnel que la vue courante 39h inclue les mois Juin-Octobre travaillés en 35h dans son cumul. Le stock CP est annuel, pas par phase ; un changement d'heures ne reset pas le compteur.
+
+## API
+
+Les endpoints suivants acceptent `?phaseId=N` :
+- `GET /employees/{id}/leave-summary`
+- `GET /employees/{id}/rtt-summary`
+
+Quand absent, ils utilisent la phase courante (comportement inchangé).
+
+`Employee.contractPhases` (lecture, groupe `employee:read`) liste les phases au format `{id, contractType, weeklyHours, isDriver, contractNature, startDate, endDate, periodIds, isCurrent}`.

+# Vue contrat (sélecteur de phase) — Design Spec
+
+## Objectif
+
+Permettre à la RH de consulter les onglets Congés et RTT d'un employé **selon le contrat actuel ET selon ses contrats passés**, sans changement de comportement par défaut.
+
+Cas qui motive : un employé passe de 39h à FORFAIT. Tant que le contrat courant est FORFAIT, les soldes CP/RTT accumulés sous l'ancien contrat 39h sont invisibles ou faussés (l'onglet RTT est masqué, la période Congés passe de Juin→Mai à Jan→Déc, les règles d'acquisition appliquent du FORFAIT_218 à toute année consultée). Conséquence : la RH ne peut plus payer les soldes restants.
+
+Le même verrou existe pour toute fin de contrat avec **solde de tout compte** (notamment fin de CDD) suivie d'un nouveau contrat de type différent.
+
+## Principe directeur
+
+> Une fois passé en contrat X, on utilise toutes les règles X par défaut. Le sélecteur permet de revenir sur les phases passées pour les consulter et solder leurs reliquats.
+
+## Concept de "phase de contrat"
+
+Une **phase** est un groupe d'`EmployeeContractPeriod` consécutifs (triés par `startDate`) partageant la même **signature contractuelle** = `(contract.type, weeklyHours, isDriver)`. La fusion s'arrête dès qu'une période diffère sur l'un de ces trois axes, même si une période identique apparaît plus tard.
+
+La signature inclut `weeklyHours` et `isDriver` parce que :
+- `weeklyHours` détermine les tranches d'heures supp (25%/50%), le rythme d'acquisition CP (cas 4h), la base contractuelle quotidienne.
+- `isDriver` change l'écran (`/driver-hours` vs `/hours`) et les colonnes de WorkHour utilisées pour le calcul RTT.
+
+Exemples :
+- CDD 39h → CDI 39h → FORFAIT : 2 phases (`39h`, `FORFAIT`).
+- CDD 35h → CDI 39h : 2 phases (`35h`, `39h`).
+- 3 CDD 39h consécutifs sans interruption : 1 phase (`39h`).
+- 39h → INTERIM 4 mois → 39h : 3 phases (les `39h` ne fusionnent pas à travers l'`INTERIM`).
+- CUSTOM 28h → CUSTOM 30h : 2 phases (`weeklyHours` diffère).
+- 35h non-driver → 35h driver : 2 phases (`isDriver` diffère).
+
+La règle de groupement vit dans un service backend, pas dans le frontend.
+
+## Backend
+
+### Nouveau service `EmployeeContractPhaseResolver`
+
+Localisation : `src/Service/Contracts/EmployeeContractPhaseResolver.php`.

+```php
+public function resolvePhases(Employee $employee): array;

+| `contractType` | `ContractType` | Type partagé par les périodes du groupe. |

+| `startDate` | `DateTimeImmutable` | `startDate` de la première période. |
+| `endDate` | `?DateTimeImmutable` | `endDate` de la dernière période, ou `null` si en cours. |
+| `periodIds` | `list<int>` | IDs des périodes composant la phase, par ordre chronologique. |

+
+### Exposition API
+
+Nouveau computed field sur `Employee` (lecture seule, groupe `employee:read`) :
+
+```json
+"contractPhases": [
+  { "id": 42, "contractType": "FORFAIT", "weeklyHours": 39, "isDriver": false, "startDate": "2026-05-01", "endDate": null, "isCurrent": true },
+  { "id": 17, "contractType": "THIRTY_NINE_HOURS", "weeklyHours": 39, "isDriver": false, "startDate": "2020-06-01", "endDate": "2026-04-30", "isCurrent": false }
+]
+```
+
+Le calcul se fait à la sérialisation via un getter virtuel `Employee::getContractPhases(): array` qui délègue au resolver.
+
+### Endpoints impactés
+
+Les endpoints `GET /employees/{id}/leave-summary` et `GET /employees/{id}/rtt-summary` acceptent un nouveau paramètre optionnel :
+
+- `?phaseId=N` : id de la phase à consulter.
+- Si absent → phase courante (= comportement actuel inchangé).
+- Si invalide (phase n'appartient pas à l'employé) → 422.
+- `?year=YYYY` reste accepté en parallèle et continue de cibler un exercice précis.
+
+### Modifications des providers
+
+**`EmployeeLeaveSummaryProvider`** :
+- Nouvelle méthode `resolveTargetPhase(Employee $e, ?int $phaseId): ContractPhase` qui retourne la phase demandée ou la phase courante.
+- `resolveLeavePolicy(...)` reçoit la phase au lieu de lire `$employee->getContract()`. Le `contract.type` et le `weeklyHours` viennent de la signature de la phase (homogène par construction).
+- `resolvePeriodBounds(...)` : les bornes de l'exercice sont en plus contraintes à `[max(periodStart, phase.startDate), min(periodEnd, phase.endDate ?? periodEnd)]`.
+- `resolveYear(...)` : si `phaseId` fourni et pas de `year` explicite, default = dernier exercice intersectant la phase (= année de `phase.endDate` ou année courante si phase en cours).
+- Si `?year` est fourni hors de la plage des exercices intersectant la phase → **clamp silencieux** à l'exercice valide le plus proche, pas d'erreur 422 (cohérence avec l'expérience picker frontend).
+- `resolveAccrualCalculationEndDate(...)` et `resolveTakenCalculationEndDate(...)` : caps additionnels sur `phase.endDate` quand la phase n'est pas la phase courante.
+- `resolveFirstComputationYear(...)` : restreint aux exercices intersectant la phase.
+
+**`EmployeeRttSummaryProvider`** :
+- Mêmes principes : `?phaseId` côté API, `resolveTargetPhase`, bornes d'exercice cappées à la phase, `rttStartDate` exposé pour borner le sélecteur d'année frontend.
+- Pour une phase FORFAIT, le tab RTT est masqué frontend, donc l'endpoint n'est pas appelé en pratique. Pas de garde spécifique côté backend, le comportement existant (retour d'un summary potentiellement vide/inutile) suffit.
+
+### Paiements de solde
+
+**RTT — `EmployeeRttPaymentProcessor`** :
+- Garde actuelle "exercice courant uniquement" devient : "exercice courant OU dernier exercice d'une phase clôturée".
+- Concrètement, autoriser la création d'un `EmployeeRttPayment` sur l'exercice contenant `phase.endDate` d'une phase non courante.
+- Les exercices antérieurs au dernier de la phase restent verrouillés (lecture seule).
+
+**CP — settlement period-level** :
+- Le mécanisme existant `EmployeeContractPeriod.paidLeaveSettledClosureDate` reste le canal pour solder. Aucun changement de modèle.
+- Le bouton "Année N-1 payés" (FORFAIT) et "Jours fractionnés" (non-FORFAIT) restent désactivés sur une phase passée — ce ne sont pas des paiements de solde mais des éditions de stock.
+
+### Audit
+
+- La création d'`EmployeeRttPayment` est déjà auditée (existant).
+- La modification de `paidLeaveSettledClosureDate` est déjà auditée via `EmployeeContractPeriodManager` (existant).
+- Aucun audit nouveau requis.
+
+## Frontend
+
+### Picker
+
+- Composant `MalioSelect` placé dans `pages/employees/[id].vue`, dans le header de la fiche, sous le nom de l'employé et au-dessus de la barre d'onglets.
+- Libellé : `Vue contrat`.
+- Options formatées :
+  - `FORFAIT — depuis 01/05/2026 (actuel)`
+  - `39h CDI — 01/06/2020 → 30/04/2026`
+- **Caché** si `contractPhases.length <= 1` (employé mono-phase, ~majorité des cas).
+- Sélection en mémoire (état du composable), **non persistée** entre navigations ou rechargements. Chaque ouverture de fiche démarre sur la phase courante.
+
+### Bandeau d'information
+
+Affiché quand `selectedPhase.id !== currentPhase.id` :
+
+> Vous consultez l'historique **{contractType} — jusqu'au {endDate}**.  
+> Les paiements de solde sont possibles ; l'édition d'absences et des stocks de report est désactivée.
+
+Style : bandeau jaune doux (`bg-warning-100 border-warning-300`), sous le picker, au-dessus des onglets.
+
+### Composables
+
+**Nouveau `useEmployeeContractPhase()`** :
+- État : `selectedPhase`, `currentPhase` (computed depuis `employee.contractPhases`).
+- Computed : `availablePhases`, `isViewingPastPhase`.
+- API : `setSelectedPhase(phaseId)`, `resetToCurrent()`.
+- `resetToCurrent()` appelé au changement d'employé.
+
+**`useEmployeeLeave`** :
+- Reçoit `phaseId` en paramètre lors des appels à `getEmployeeLeaveSummary` / `listAbsences`.
+- `availableLeaveYears` borné aux exercices intersectant la phase sélectionnée.
+- `setSelectedPhase` côté parent → reset de `selectedLeaveYear` et reload.
+
+**`useEmployeeRtt`** :
+- Idem pour `getEmployeeRttSummary`, `availableRttYears`.
+
+**`useEmployeeDetailPage`** :
+- `showRttTab` devient : `selectedPhase.contractType !== FORFAIT`.
+- La logique de fallback ("si sur l'onglet RTT et FORFAIT, basculer ailleurs") s'applique aussi quand on bascule de phase 39h vers phase FORFAIT.
+
+### Onglets
+
+- **Congés** : reçoit la phase via le composable. Bouton "Année N-1 payés" / "Jours fractionnés" reste désactivé sur phase passée (idem que sur exercice passé).
+- **RTT** : visibilité driver par la phase. Bouton "+ Payer les RTT" activé **uniquement sur le dernier exercice de la phase passée**, désactivé sur les exercices antérieurs de la phase.
+- **Heures, Frais, Formation, Contrat, Calendrier** : non impactés.
+
+### Format des libellés du picker
+
+Format de la phase : `{labelContractType} — {startDateFR} → {endDateFR}`, suffixé `(actuel)` si phase courante.
+
+`labelContractType` mapping :
+- `FORFAIT` → `FORFAIT`
+- `THIRTY_FIVE_HOURS` → `35h`
+- `THIRTY_NINE_HOURS` → `39h`
+- `INTERIM` → `Intérim`
+- `CUSTOM` → `CUSTOM ({weeklyHours}h)` (les heures hebdo sont homogènes par construction dans une phase)
+
+Suffixe `(driver)` ajouté quand `isDriver=true`, ex. `35h CDI (driver) — ...`.
+
+## Migration et impact sur l'existant
+
+- Aucune migration de données. Le concept de phase est calculé à la volée depuis l'historique existant.
+- Comportement inchangé pour tout employé avec une seule phase (cas standard).
+- Comportement inchangé quand `phaseId` n'est pas fourni → phase courante.
+- Pas de breaking change API : `contractPhases` est un champ additionnel ; `?phaseId` est un paramètre optionnel.
+
+## Tests
+
+### Unit
+
+- `EmployeeContractPhaseResolverTest` :
+  - Employé mono-période → 1 phase, `isCurrent=true`.
+  - Trois périodes même signature consécutives → 1 phase.
+  - Switch 39h → FORFAIT → 2 phases avec `startDate`/`endDate` correctes.
+  - 39h → INTERIM 4 mois → 39h → 3 phases (pas de fusion).
+  - 35h → 39h → 2 phases (type différent).
+  - CUSTOM 28h → CUSTOM 30h → 2 phases (`weeklyHours` diffère).
+  - 35h non-driver → 35h driver → 2 phases (`isDriver` diffère).
+
+### Functional
+
+- `EmployeeLeaveSummaryProvider` avec `phaseId` :
+  - Phase 39h passée → `ruleCode = CDI_CDD_NON_FORFAIT`, période Juin→Mai, exercice de transition capé à `phase.endDate`.
+  - Phase FORFAIT passée → `ruleCode = FORFAIT_218`, période Jan→Déc.
+  - `phaseId` invalide pour l'employé → 422.
+  - `?year` hors de la plage de la phase → clamp silencieux à l'exercice intersectant le plus proche.
+
+- `EmployeeRttSummaryProvider` avec `phaseId` :
+  - Phase 39h passée → données RTT renvoyées, bornes cappées sur `phase.endDate`.
+  - `?year` hors de la plage de la phase → clamp silencieux.
+
+- `EmployeeRttPaymentProcessor` :
+  - Création autorisée sur exercice de fin d'une phase passée.
+  - Création refusée sur un exercice antérieur d'une phase passée.
+
+### Documentation à mettre à jour
+
+Obligatoire par CLAUDE.md :
+
+- `doc/contract-phase-view.md` — nouveau fichier détaillant la fonctionnalité.
+- `doc/leave-tab.md` — section "Sélecteur de phase" + interaction avec le sélecteur d'année.
+- `doc/rtt-tab.md` — section "Sélecteur de phase" + règle de visibilité.
+- `frontend/data/documentation-content.ts` — article niveau `admin`.
+- `CLAUDE.md` — bloc "Vue contrat (sélecteur de phase)" sous Onglet Congés / Onglet RTT.
+
+## Hors scope
+
+- Surface d'alerte automatique sur les fiches employés ayant des soldes non payés sur des phases passées (potentiel follow-up).
+- Persistance de la sélection du picker entre navigations.
+- Picker exposé sur le calendrier global ou tout autre écran que la fiche employé.
+- Modification de `WorkHourDayContext` (déjà date-driven, pas concerné).
+- Évolution du mécanisme `paidLeaveSettledClosureDate` (canal existant suffisant).
+- Cas exotiques : phases overlap (interdit par la modélisation actuelle), périodes avec dates incohérentes.
+
+## Décisions confirmées avec l'utilisateur
+
+- Picker global en haut de la fiche, **pas** par onglet.
+- Phases groupées par `contract.type` consécutif.
+- Sur une phase passée : exercices antérieurs visibles **en lecture seule**, seul le dernier exercice de la phase ouvre les actions de solde (RTT pay, CP settlement period-level).
+- Comportement par défaut (phase courante) strictement inchangé.
