Executable Canonicalizer SSOT Recheck

Verdict

CANONICALIZER_SSOT_FAIL

Exactly one artifact is labelled load-bearing, but it is not executable as contracted.

Evidence

• Declared command names canonicalizer-fix7-canon-v1-ssot.py; that file does not exist in the workspace and invocation exits 2.
• The load-bearing artifact is Markdown; no byte-exact rule extracts its Python fence into the declared .py file.
• Embedded code has no production CLI and no functions that compute active_corpus_sha256, marker_fence_registry_sha256, superseded_boundary_sha256, guard_set_sha256, envelope_manifest_sha256, or detached_seal_sha256.
• The artifact promises outputs it cannot produce.
• It permits a reimplementation proven only against incomplete test vectors, allowing behavior outside those vectors to diverge.

Required T1 fix

Provide one runnable scoped artifact, or an exact extraction rule plus runnable command, implementing the entire production sealing pipeline and emitting all required fields. Pin its full bytes and complete conformance vectors.
