The evaluator now exists: judgment-pack-runtime#19 implements this RFC's pinned semantics behind an explicitly experimental, non-conformance-claiming surface (runtime ADR-0007), with the nine appendix instances as its acceptance tests — reproduced identically over CLI and MCP.

This amendment records the implementation experience RFC 0000 asks for:

  • the restated step 2 was implementable exactly as written (7a/7b deterministic);
  • number representability is a real gap — extreme exponents make equality undeterminable; mapped to §7.4's incomparable→unknown, added as an unresolved question;
  • §8.1's no-destination direct escalation shape needs confirming in the later draft;
  • honoring additionalProperties: false requires strict wire-argument decoding.

Also pins the independence bar for implementation #2: derived from the RFC text, never ported from the first implementation. 45 tests pass; site builds.

The Go reference runtime now implements the RFC's pinned semantics
behind its explicitly experimental, non-conformance-claiming surface
(its ADR-0007); the nine appendix instances run as its acceptance tests
and reproduce identically over both of its surfaces. Record the
implementation experience RFC 0000 asks for: the restated step 2 was
implementable as written; number representability is a real gap (extreme
exponents make equality undeterminable -- mapped to section 7.4's
incomparable-produces-unknown, with a new unresolved question); the
no-destination direct escalation shape needs confirming; honoring
additionalProperties: false requires strict wire-argument decoding.
Also states the independence bar for the second implementation: derived
from this RFC's text, never ported from the first.

Draft amendment; no normative text exists yet to change.
