fieldtest: blueprint-name — 4 examples, 1 bug / 0 friction / 1 spec-gap / 4 working

Source-blind consumer run over the four cycle axes on the release
binary at 4ff85b9: the authoring loop lands the name in bytes, store
document, and traces/<name>/ (with the documented default collision
observable on the unnamed twin); the refusal battery is uniform and
op-indexed across the op route and the file intakes; a named blueprint
defaults its use-splice instance identifier as documented, two unnamed
splices collide, two named ones coexist; help/guide/glossary agree on
eleven ops and the render-name vs registry-label split. Finding B1
(sweep --list-axes ungated, mangled listing at exit 0) is fixed
RED-first in the preceding commit; SG1 (prefix variance in the refusal
prose) is ratified there in C24.
