G.13:1 - Problem frame

FPF already supports lawful characterization, evidence wiring, selector‑side set returns, parity, shipping, dashboards, and refresh. What remains frictionful in practice is interoperability with external scholarly indexes and discipline repositories (concept registries, paper/claim graphs, dataset registries, taxonomy stores, “science‑of‑science” indicator feeds), which teams routinely use as inputs when authoring a SoTA discipline pack.

Without an explicit conceptual interop kit, authors tend to build one‑off pipelines whose “implied semantics” leak into the framework: edition drift becomes invisible, cross‑plane/context reuse becomes implicit, and external signals quietly start acting like a shadow governing spec ref.

G.13 provides the missing kit: conceptual registration, alignment, and telemetry hooks that let external sources be wired into the Part‑G pipeline (G.2 → G.5 → G.9 → G.10 → G.11, and optionally G.12) while preserving Part‑G invariants via G.Core.
