skraft-quality-bar

Use before running, verifying, or reporting any quality gate. States the one permanent threshold for mutation score and line coverage, and the enforcement level of every gate. Load when about to invoke a mutation run, when deciding whether a gate blocks or merely warns, when writing or reviewing an evidence record, when a skill or descriptor appears to state a threshold of its own, and whenever a number would otherwise be copied from memory or from an older document. There are no tiers, no advisory level, and no override. Does not choose the toolchain command (resolving-stack-commands), classify survivors (mutation-testing), define the evidence schema (quality-gates-evidence-contract), or set the reviewer lens count (each review-criteria skill owns its own).
