Process · medium — un ticket qui finit en remboursement

Le cas. Celui de l'exemple avancé de la version actuelle, avec ce qui lui manquait : l'ordre, l'approbation, la provenance des valeurs, l'autonomie encadrée, l'ouverture automatique.

Ce que l'exemple montre. Des lectures qui laissent une trace et ouvrent les tâches suivantes ; une méthode choisie par règle (remboursement si la facture est payée, avoir sinon) ; une approbation au-delà de 50 € ; un montant et un destinataire que le modèle ne peut pas fixer ; une politique de fraude ; une classe sécurité ; des politiques nommées (plafond-facture, validation-manager) qui se retrouvent telles quelles dans le registre ; un budget par agent ; une clé unique par facture ; un agent autorisé à soumettre seul les petits montants ; une boîte Teams pour le manager — distincte des portails Teams et Slack où l'agent de la station parle aux équipes support. Côté événements : le ticket arrive par un webhook déclaré et signé, et le remboursement terminé est publié comme un fait, refund.completed, que le CRM reçoit.

examples/cible/process-medium.yaml
# Process · medium — CIBLE. Ticket → refund, as ADR-030 runs it.
# Reads that leave a trace, an order enforced at select, a choice of method by rule, an approval
# before reservation above 50 €, an amount the model cannot invent, a recipient it cannot change,
# a smart fraud policy that only asks for a human, an agent allowed to submit small refunds.
# Events: the ticket arrives as a declared, signed webhook; the finished refund is published as a
# business fact (`refund.completed`) that the CRM receives — a delivery (outbound), not an action.

Ce qui se passe

ce qui arrive	qui décide	résultat
le webhook `zendesk.ticket.created` arrive, tagué `billing`	signature et identifiant vérifiés ; automatisation déterministe	`ticket-refund` s'ouvre dans la room du ticket, pour l'agent de support
Zendesk rejoue le même webhook	`id`	ignoré : pas de deuxième parcours
`read-ticket`	la tâche `ticket` s'ouvre	lue ; trace « Ticket #4182 · Awa D. »
« rembourse 120 € » avant la facture	l'ordre	refusé : « facture non vérifiée »
`check-invoice`	lue : payée, 120 €	la méthode `remboursement` s'applique
remboursement de 120 €	`amount ≤ max_amount`, `checkRefundPolicy`, fraude 0,32, budget	puis `approval` (> 50 €) : en attente dans Teams
le manager approuve	l'action n'a pas changé depuis	réservée
la réponse est dirigée vers une autre adresse	`recipient` : `set_by: [read, identity]` ; injection 0,95	refusé (classe sécurité)
submit à 120 €	`submitted_by` : la règle agent ne tient pas (> 50)	le manager soumet ; puis `createRefund`, puis `sendReply`
un deuxième ticket pour la même facture	`unique`	refusé : déjà réservée ailleurs
un remboursement de 30 €, agent autonome	`submitted_by` : règle agent	l'agent soumet ; le reçu dit sous quelle règle
le modèle est indisponible	`fraude.on_unavailable: needs-human`	tout passe par le manager : plus lent, jamais moins sûr
le manager n'a pas répondu en 2 h	`relancer-approbation`, sur `approval.requested`	relancé, avant l'escalade de la boîte à 4 h
le playbook est finalisé	`events.emits`	`refund.completed` est émis, sans l'e-mail du client ; le CRM le reçoit, signé
le CRM ne répond pas	`events.outbound`	réessais, puis `delivery.failed` dans la console. Le remboursement n'est pas annulé.

À retenir

L'approbation se fait au choix, avant la réservation, sur l'action finale. Le submit exécute.
Prévenir le CRM est une livraison, pas une action : rien ne change chez lui sans lui.
La skill refund ne cite aucune tâche : c'est le playbook qui lui donne la facture. Elle peut servir dans un autre parcours.
