C.22:5.4 - Attachment & use.

The bullets below state which TaskSignature fields and relations each downstream use reads. C.22 does not execute eligibility, acceptance, selection, archive treatment, or generator-family choice. Their verdicts and returned sets remain results of the named direct patterns.

• Eligibility gates read TaskSignature against each MethodFamily.Eligibility (C.23) and CG‑Spec.MinimalEvidence for referenced characteristics.
• Acceptance clauses (G.4) use these fields for acceptance-gate threshold predicates (acceptance-gate thresholds live in Acceptance only).
• Selection kernel (G.5.S3) applies an admissible order (often partial); weighted sums across mixed scale types are inadmissible. If only a partial order remains, return a Pareto (non‑dominated) set with tie notes. If PortfolioMode=Archive, the selector may return a QD archive (per ArchiveConfig) in addition to or instead of a Pareto set. Illumination enters dominance only if DominanceRegime=ParetoPlusIllumination is enabled by CAL (policy id cited); otherwise, QD telemetry values are reported but excluded from dominance.
• When GeneratorIntent is present, G.5-governed selection may use a registered GeneratorFamily (POET‑class); the selection domain becomes pairs {environment, method}, with Environment guarded by EnvironmentValidityRegion and TransferRulesRef (C.23 wiring). Report IlluminationSummary as a telemetry summary over Diversity_P (report‑only by default) in telemetry; dominance remains unaffected unless policy changes as above.
