Version: Target · roadmap

Process · medium — a ticket that ends in a refund

The case. The one from the current version's advanced example, with what it lacked: order, approval, provenance of values, bounded autonomy, automatic opening.

What the example shows. Reads that leave a trace and open the next tasks; a method chosen by rule (refund if the invoice is paid, credit note otherwise); an approval above €50; an amount and a recipient the model cannot set; a fraud policy; a security class; named policies (plafond-facture, validation-manager) that appear as they are in the registry; a budget per agent; a unique key per invoice; an agent allowed to submit small amounts on its own; a Teams inbox for the manager — distinct from the Teams and Slack portals where the station's agent talks to the support teams. On the events side: the ticket arrives through a declared, signed webhook, and the completed refund is published as a fact, refund.completed, which the CRM receives.

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.

What happens

what happens	who decides	result
the `zendesk.ticket.created` webhook arrives, tagged `billing`	signature and identifier verified; deterministic automation	`ticket-refund` opens in the ticket's room, for the support agent
Zendesk replays the same webhook	`id`	ignored: no second journey
`read-ticket`	the `ticket` task opens	read; trace "Ticket #4182 · Awa D."
"refund €120" before the invoice	the order	refused: "invoice not verified"
`check-invoice`	read: paid, €120	the `remboursement` method applies
refund of €120	`amount ≤ max_amount`, `checkRefundPolicy`, fraud 0.32, budget	then `approval` (> €50): pending in Teams
the manager approves	the action has not changed since	reserved
the reply is directed to another address	`recipient`: `set_by: [read, identity]`; injection 0.95	refused (security class)
submit at €120	`submitted_by`: the agent rule does not hold (> 50)	the manager submits; then `createRefund`, then `sendReply`
a second ticket for the same invoice	`unique`	refused: already reserved elsewhere
a refund of €30, autonomous agent	`submitted_by`: agent rule	the agent submits; the receipt says under which rule
the model is unavailable	`fraude.on_unavailable: needs-human`	everything goes through the manager: slower, never less safe
the manager has not answered in 2 h	`relancer-approbation`, on `approval.requested`	reminded, before the inbox escalation at 4 h
the playbook is finalised	`events.emits`	`refund.completed` is emitted, without the customer's email; the CRM receives it, signed
the CRM does not respond	`events.outbound`	retries, then `delivery.failed` in the console. The refund is not cancelled.

Key points

Approval happens at choice, before reservation, on the final action. The submit executes.
Notifying the CRM is a delivery, not an action: nothing changes on its side without it.
The refund skill names no task: the playbook gives it the invoice. It can serve in another journey.
