The master spec at experiments/2026-05-12-cross-model-authoring/ master/spec.md taught two wrong Form-A keywords: - Term position: `(ctor TYPE-NAME CTOR-NAME ARG*)` — parser rejects this; the canonical keyword is `term-ctor`. The bare `(ctor ...)` is reserved for the inside of `(data ...)` definitions only. - Pattern position: `(ctor CTOR-NAME SUBPAT*)` — the canonical pattern keyword is `pat-ctor`. The JSON section was already correct (canonical schema tag IS "t": "ctor", per ast.rs:471). Only the AIL section had drifted. Empirically caught by the Qwen3-Coder naming-A/B run on 2026-05-21 (experiments/2026-05-21-naming-ab/runs/r1/), where every t4_count_zeros output produced `(ctor List Nil)` in term position and failed `ail check` 100 % across all three cohorts — a constant tax independent of the naming variable under test. Re-rendered rendered/ail.md from the patched master via xmodel-render. rendered/json.md unaffected. closes #28
