C.31:6 - Bias-Annotation

Bias risk	C.31 repair
Scalar bias	Refuse one modularity score unless scoring method and comparability basis are declared.
Measure-first bias	Start with `ModularityVectorLite` and repair direction before C.16-heavy fields.
Interface-publication bias	Treat public interfaces as only one possible basis for substantiating substitutability.
Proxy bias	Add `proxyRisk` and `auditQuestion` to every decision-facing card.
Complexity umbrella bias	Keep residual heads claim-scoped and apply scale, RG, or lens subject patterns when those uses are being made.
Source-label bias	Treat software, neural-network, chiplet, safety-case, product-line, block, layer, expert, cache, router, and gate labels as source examples until `C.30.STRAT` and the subject pattern recover the FPF characteristic subject, structure, scale, and admissible use.
