A.19.UINDM:0 - At a glance (didactic, informative)

• Suite stage: indicatorize (ordering lives only in A.19.CHR:suite_protocols).
• Inputs (conceptual): exact U.CharacteristicSpaceRef, CNSpecRef, and IndicatorChoicePolicyRef, with the bearer, claim scope and selected slices, qualification window, evidence basis, and intended use declared by those editions; when the selected policy is evidence-gated, also supply CGSpecRef and, optionally, a MinimalEvidenceRef override.
• Output: IndicatorSetSlot = S⊆I, a set of positions in the exact A.19 space declaration’s ordered basis I. Each position retains its Characteristic, Scale and meaning. The selection is not a measurement or conversion.
• Non‑goals: does not normalize, score, compare, aggregate, threshold, publish, or emit telemetry; it only selects a subset under explicit policy.
• P2W seam: the A.15.2 baseline records concrete space/spec/policy editions; A.15.3 typed filling applies only to independently declared positions. Actual use retains its effective refs and pins in Audit.
• Failure mode: tri‑state guard (pass|degrade|abstain); unknown never coerces to pass.
• Quick rule of thumb: if CN‑Spec.indicator_policy is absent → IndicatorizeEligibility = abstain (fail‑closed); if the selected policy is evidence‑gated → CGSpecRef MUST be available and the effective MinimalEvidence MUST be explicit (override or CG‑Spec.MinimalEvidence).
