Pins the special-form surface the kernel actually has: `Space::interpret` accepts `(exec <loc> <patterns> <templates>)` with pattern functor `,` or `I` and template functor `,` or `O`, and `metta_calculus` removes an exec before interpreting it, so a rejected exec is consumed without effect. Six behavior tests cover the `,`/`,` rewrite, the `I`/`O` path (a `(== pat $r)` source binding the matched atom, `(+ ...)` add and `(- ...)` remove sinks), the three rejection shapes (bad template functor, bad pattern functor, symbol pattern), and template-written execs being scheduled like any other (self-scheduling). Replaces the earlier FormalMeTTa classifier parity tests: Empty / NotReducible / Unit / Error are interpreter-layer results that the MORK kernel does not implement, so classifying them belongs to the interpreter above MORK; the kernel-real contract is the exec shape dispatch, which these tests pin against the live engine with no new kernel code.

The kernel-real special-form surface is the exec shape dispatch, which is also modeled in Alloy (github.com/MesTTo/alloy-mork: fac25 — dispatch totality on valid shapes, rejection otherwise, io flags mirroring the functors).
