Deterministic chemical review rubric
renkin audit-route can emit an optional chemical_review block:
The rubric is deliberately an evidence boundary, not a route-quality score.
It reports a stable rubric_version, judge_id, dimension, reason code,
severity, and one of pass, review, or not_evaluable.
The deterministic judge currently covers structural audit, configured stock,
and declared forward replay. Selectivity, experimental conditions, substrate
scope, protecting-group compatibility, and strategic route quality are
not_evaluable unless those facts are present in a future evidence-carrying
interchange record. The command never fabricates conditions or turns missing
evidence into a chemical failure.
The block is opt-in and absent from the default JSON report, preserving the
existing audit-route output contract. Human or LLM review may be layered on
later by recording its judge identity, model/version, rubric version, verdict,
and confidence separately from this deterministic result.
