A.6.C:5.3 — Show (Episteme archetypes)

(C) Multiparty protocol boundary (behavioural and session-type motif)

Draft wording: “The protocol guarantees progress. Participants must follow the sequence.”

Source clauses and additional illustrative premises:

The progress guarantee still needs its semantic or operational meaning. For the illustrative case below, assume the published protocol description and the trace-admissibility criteria; the named trace evaluation is an additional hypothetical case.

  • Description/publication: protocol description (could be a type spec or protocol spec plus explanatory views).
  • L — when the guarantee is semantic: the progress property is a law over the protocol model (truth-conditional, within the theory).
  • A: admissibility: when an interaction trace is considered valid or admissible (e.g., runtime checks; compilation checks; gating conditions for entering a session).
  • D: the protocol description generically requires covered participants to follow the stated sequence. It asserts no individual commitment occurrence.
  • E — additional hypothetical trace evaluation, not inferred from the progress guarantee: suppose admitted system ProtocolConformanceEvaluator-A performed ProtocolConformanceRun-T1 : U.Work over bounded interaction Trace-42. Exact A.6.1 application ProtocolConformanceApplication-T1 has result binding conformanceResult -> ProtocolConformanceResult-T1; that C.2.1 result episteme states conformanceVerdict=pass and observedTerminalState=completed under ProtocolConformanceCriterion-v5. For a disputed interaction, an A.10 path links this result to exact MessageTrace-42, ConformanceRunRecord-T1, and ProtocolAuditRecord-42 carriers.

(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 + classify:

  • Promise content (service promise clause, when present): a responsiveness promise for a defined incident class and window is separate from the SLA’s generic prescription.
  • Description/publication: SLA publication (and its views for different audiences).
  • A: admissibility predicate for the promise: ticket qualifies iff severity classification meets stated conditions.
  • D: the SLA clause generically requires the covered Provider to respond within 4 hours for Severity-1 incidents; only Severity-1 is covered. Claim that actual provider ProviderSystem-A bears the four-hour duty only after the SLA’s individualizing rule and required actual basis establish one exact A.2.8 commitment; otherwise keep the clause generic.
  • Evidence source clause: the draft names ticket logs as evidence; it supplies no measured response interval.
  • E — additional hypothetical response evaluation: suppose admitted system SLAEvaluator-A performed ResponseEvaluation-Ticket-17 : U.Work over Severity-1 ticket Ticket-17 under the declared clock and measurement method. Exact A.6.1 application ResponseMeasurementApplication-Ticket-17 has result binding responseIntervalResult -> ResponseIntervalResult-Ticket-17; that C.2.1 result episteme states observedResponseInterval=3h42m and withinFourHourTarget=true. When the SLA decision relies on this result, an A.10 path links it to exact ticket, response-timestamp, clock-source, and severity-classification carriers. The four-hour requirement is from the source; 3h42m is the additional hypothetical observation.
