Three of the four immediate fieldtest findings for the self-description cycle: - authoring-guide S0: the worked Scale literal gains the required NodeSchema.doc line (+ the C29 comment) -- the shipped example was a hard E0063 for anyone pasting it (the exact #314 teaching-failure class, caught from the consumer seat). - The op table becomes "The nine ops": the C29 doc op is documented with its JSON shape, the register requirement, the at-most-once rule and the gate; the README op-kinds list names it too. The fieldtester had to guess the shape from commit bodies -- now it is on the public surface. - The store-gate refusal's fix hint is surface-neutral: builder .doc(...), blueprint "doc" member, or op-script {"op":"doc"} -- previously it prescribed the Rust builder to a JSON author. Gates: registry, graph_construct (63) and project_load (14) suites green; refusal-prose pins unchanged (pinned substrings untouched). refs #316
