#G.Core:5 - Archetypal grounding

Preface node heading:g-core-5-archetypal-grounding:54589

#Content

Tell. In Phase‑2 refactoring, G.Core is the hub that allows each G.x to become structurally predictable: (a) a short, normative “Core linkage” slice, and (b) pattern‑scoped Extensions. Universal obligations are routed to canonical owners (A.6.7 / A.15.3 / A.19 / G.0 / A.19.CHR), while RSCR causes and default ownership become typed and single-owned.

Show 1: Refresh triggers without semantic drift. G.11 already uses trigger tokens T0…T7. G.Core keeps them as aliases and maps them to canonical trigger kinds (e.g., TelemetryDelta, EditionPinChange, CrossingBundleEdit). This makes RSCR reason codes consistent across patterns and avoids re-explaining trigger semantics in every pattern.

Show 2: Resolving competing defaults. If multiple patterns imply a default for PortfolioMode, the Default Ownership Index points to a single owner (currently CC‑G5.23). Other patterns (e.g., bundles/log patterns) must cite that owner or delegate to it, rather than restating the default with slightly different wording. This preserves intent while preventing drift and ambiguity.
