G.1:4.2.3 - M3 — VariantPool (candidate inventory + emitter trace)

Governs (kit surface):

  • VariantPoolId bound to CG‑FrameContext
  • per‑candidate minimal traceability fields (emitter identity, EmitterPolicyRef (policy‑id/ref; defined by the governing pattern), method/generator refs when declared, edition pins, provenance anchors)
  • optional, per‑candidate assurance preview pointers (e.g., PathSliceId? and/or SCRId? when early assurance is recorded) and optional QD/Open‑Ended scaffolding stubs (only when introduced by explicit GPatternExtension blocks)

Guardrails (via G.Core):

  • tri‑state eligibility handling, penalties routing, crossing visibility, and set‑return constraints are not defined here; they are enforced via G.Core conformance.

Governing pattern for method payload: method‑specific emitter semantics remain in their governing definitions, cited through Extensions (e.g., the relevant C.17, C.18, and C.19 definitions). M3 MUST remain method‑agnostic in its core definition: it is an inventory surface, not an algorithm spec.
