Content
(C) Multiparty protocol boundary (behavioural/session type motif)
Draft wording: “The protocol guarantees progress. Participants must follow the sequence.”
Unpack + route:
- Utterance: protocol description (could be a type/protocol spec plus explanatory views).
- L: safety/progress properties as laws over the protocol model (truth-conditional, within the theory).
- A: admissibility: when an interaction trace is considered valid/admissible (e.g., runtime checks; compilation checks; gating conditions for entering a session).
- D: obligations on implementers/operators: implement the protocol; do not send messages outside the allowed state machine; publish conformance artefacts if required.
- E: evidence: message trace carriers; conformance test run artefacts; audit trails for disputed interactions.
(D) Socio-technical “SLA + audit trail” boundary
Draft wording: “Provider shall respond within 4 hours for Severity‑1 incidents. Only Severity‑1 is covered. Evidence is provided by ticket logs.”
Unpack + route:
- Promise content (service promise clause): responsiveness promise for a defined incident class and window.
- Utterance: SLA publication (and its views for different audiences).
- A: admissibility predicate for the promise: ticket qualifies iff severity classification meets stated conditions.
- D: provider commitment to meet the target; client duties (e.g., provide required info); auditor duties if applicable.
- E: evidence: ticket carriers, timestamps, classification records, and the measurement procedure binding “4 hours” to a time window and clock source.
