Paper quality gate

Internal deterministic gate used after bounded LaTeX sanitization and immediately before compilation. Input is a JSON object containing paper_contract, length_gate, citation_gate, and manuscript_package. The preceding sanitizer may normalize safe punctuation and replace detected forecast magnitudes with explicit placeholders, but this gate remains an independent fail-closed audit of the resulting artifact.

The command exits non-zero when an upstream LLM gate blocks, when a required verdict marker is absent, when the manuscript artifact cannot be read, or when an evidence-free manuscript presents empirical findings as completed results. It also rejects concrete English or Chinese predicted outcome numbers (for example, an anticipated 12% improvement) when evidence is absent. Experimental setup parameters remain allowed; a predefined metric target such as 50% accuracy is also allowed when the unknown time-to-target remains nonnumeric. Explicitly conditional claims and planned significance thresholds are not treated as observed findings. Unknown outcomes must use TBD / 待实验确定 instead of invented point estimates.
