su3_mask_report
plain-language theorem explainer
su3_mask_report produces a status string for an SU(3) braid mask certificate built from an input source string. LNAL compiler pipelines would invoke it during invariant validation runs. The definition is a direct wrapper that calls SU3MaskCert.fromSource and returns either an OK placeholder or a semicolon-separated error list.
Claim. The map $f : String → String$ is defined by forming the SU(3) braid mask certificate $c$ from the input string $s$, then returning the string ``OK: SU(3) braid mask (placeholder)'' when $c$ is valid and otherwise the string ``FAIL:'' followed by the concatenated list of $c$'s error messages.
background
The LNALReports module supplies human-readable output functions for artifacts produced by the LNAL compiler. SU3MaskCert is the structure that records whether the SU(3) invariant is preserved under lStep transitions; its doc-comment states ``SU(3) braid mask certificate: SU3Invariant preserved under lStep.'' The single dependency is the fromSource constructor of this certificate, which extracts the ok flag and error list from the supplied source string.
proof idea
one-line wrapper that applies SU3MaskCert.fromSource to the input source string, then branches on the resulting ok field to select the success placeholder or the interpolated error string.
why it matters
The definition supplies the reporting interface for the SU(3) braid mask certificate that certifies preservation of the SU3Invariant inside LNAL programs. It therefore supports the LNAL compiler validation layer that sits above the Recognition Science forcing chain (T0–T8) and the Recognition Composition Law. No parent theorems or downstream uses are registered, so the declaration remains an open reporting hook for future integration with J-budget or phi-ladder checks.
