Sampled Values Conformance and Interoperability Matrix
This matrix is the working control sheet for ARSVIN profile expansion. It records what is known, what remains provisional, and what evidence is required before a behavior becomes part of a supported profile.
Evidence status vocabulary

|---|---|
| Verified-standard | Confirmed from a licensed applicable standard and recorded with edition and clause. |
| Verified-official | Confirmed from an official standards-body or manufacturer document. |
| Verified-capture | Confirmed from an anonymized real-device SCL/PCAP pair. |
| Verified-lab | Confirmed by byte-exact or interoperability testing with a real counterpart. |
| Implemented-generic | Engine supports the mechanism, but no profile-specific compliance claim is made. |
| Provisional | Candidate behavior awaiting stronger evidence. |
| Unknown | Not yet researched. |

| Outcome | ARSVIN target |
|---|---|
| SCL-first system view | Import configured streams and show expected-versus-observed state. |
| Configuration versus live comparison | Compare addressing, dataset, packing, rates, and profile evidence side by side. |
| Signal tracing | Trace an SCL stream to observed traffic and decoded channels. |
| Orphan detection | List observed streams absent from SCL and expected streams absent from traffic. |
| MU parameter verification | Validate fields, rate, packing, payload, synchronization, and quality. |
| Packet interval statistics | Add intervals, jitter, gaps, bounded statistics, and evidence export. |
| Triggered recording | Add software trigger rules after profile detection is stable. |
| Redundancy verification | Keep PRP/HSR in a separate evidence-backed milestone. |
| Reusable tests and reports | Use machine-readable expected-profile fixtures and repeatable reports. |
