FSA complete:O01 status received, version 1. Stock, payment and delivery date unknown. O99 scope denied. No connected tools or actual identities. The six input rows follow:
| Row | Event | Ticket | Request | Order | Scope/evidence |
|---|---|---|---|---|---|
| 1 | E01 | T01 | Status / Estado | O01 | Scope confirmed in test / Alcance confirmado en prueba |
| 2 | E02 | T02 | Cancel request / Solicitud cancelar | O01 | Scope confirmed in test / Alcance confirmado en prueba |
| 3 | E03 | T03 | Payment claim / Afirmación pago | O01 | No payment-source evidence / Sin evidencia fuente pago |
| 4 | E04 | T04 | Status / Estado | O99 | Scope denied in test / Alcance denegado en prueba |
| 5 | E01 | T01 | Status / Estado | O01 | Exact first-row repeat / Copia exacta primera fila |
| 6 | E01 | T01 | Delivery promise request / Solicitud prometer entrega | O01 | Changed content, same event / Contenido distinto, mismo evento |
1. Define source and access contracts
A service system is more than a polite reply. State where each status comes from, which scope permits reading it and what happens when evidence is absent. FSA only lists O01 as received, version 1; delivery, stock and payment are unconfirmed. Missing values remain missing.
Each scope flag is exercise input, not implemented authentication. Operational scope must come from an authorized server, not customer text or a checkbox. FSA denies O99 scope; output must reveal or invent no order information.
Activity: define source, version, known/unknown fields, scope and prohibited outputs. Separate received from paid, cancelled and delivered. Add no identities, channels or credentials.
Worked feedback
Feedback: only cite O01 received when scope permits. No payment, delivery or cancellation is established. O99 is scope-restricted, not proven nonexistent; even that conclusion is unauthorized. This material implements no actual access control.
2. Separate service-work states from order states
Propose received, clarification needed, verification pending, draft prepared and restricted. These describe work, not O01 changes. A cancellation request may await a proposed authorized decision without cancelling an order. A payment claim may await evidence without marking paid.
E01 permits a limited received-status draft, leaving payment/delivery unresolved. E02 needs a later authorized decision;E03 needs payment-source evidence, not a message;E04 is restricted. No human owner,24/7 coverage or resolution time is promised.
Activity: draw work-state transitions with input, evidence and exit condition. Write E01 draft and an E02 proposed internal note. Label both unsent, with no order changes.
Worked feedback
Feedback:E01 limited draft;E02 proposed escalation;E03 verification pending;E04 restricted. No automatic closure or approval. Missing data must not become resolved merely to clear a queue. Work state is not action evidence.
3. Trace repetition and conflict
Row 5 exactly repeats E01/T01/status/O01. Preserve duplicate evidence without another operational reply. Row 6 reuses E01 with changed content and conflicts. Choose neither newest content nor a delivery promise; the identifier already belongs to another event.
The test model keeps a ledger for one run only. No durable persistence, cross-device deduplication or actual queue. Production would require unique keys, versions and authorized sources, not connected here. Drawing those dependencies proves no implementation.
Activity: complete six expected/observed/rule/next-review rows. Distinguish unique events, rows and tickets. Explain why six rows are not six resolved cases.
Worked feedback
Feedback:6 rows,4 distinct event IDs,4 fictional tickets, plus 1 duplicate and 1 conflict. Outcomes:1 draft,1 escalation,1 verification,1 restricted,1 duplicate,1 conflict. No order, payment, delivery or actual service is confirmed.
4. Test invariants and deliver bounded architecture
Invariants: no output executes actions, the source order stays unchanged, unknown scope grants nothing, and no text announces unverified payment/delivery. Separate variants VA:O01 source unavailable;VB:E01 scope denied;VC: delivery requested without a date. Stop or preserve unknowns instead of promising.
Deliver source contract, state/transition matrix, six tests and two unsent internal drafts. This is reviewable manual architecture, not an active support service or completed human assistance. Open no accounts, send no messages and verify no real payments.
Activity: walk through base and three variants, retain corrections, and self-inspect sources/access, transitions, traceability and limits. Use 0–2 for editorial guidance only, no approved PRO academic threshold or free-policy transfer.
Worked feedback
Feedback:VA source unavailable;VB restricted;VC delivery unresolved. Any order mutation or claim of sending fails. No grades, completed human review, statements, benefits or enrollment. Authorized operational integration and official PRO sequence/assessment remain absent.
