E01-PI: No

Rationale

On 2026-10-16 the PRP owner explicitly confirmed that no independent interoperable implementation exists. E01 is therefore No for the selected PRP profile at this date, rather than Pending on an inconclusive public search.

Assessment method

Owner-confirmed implementation availability

Source context

Direct PRP owner declaration, editorial conversation, 2026-10-16

Outstanding qualification

Dated owner declaration about implementation maturity, not a protocol limitation or failed interoperability test. Reassess when an independently developed implementation exchanges traffic in a publicly documented test, crediting only the tested functions. This statement does not decide E05 independent operation and is not an independent audit.
