G.2:4.5.1 - GPatternExtension: GammaEpistSynthesis

PatternScopeId: G.2:Ext.GammaEpistSynthesis GPatternExtensionId: GammaEpistSynthesis GPatternExtensionKind: GeneratorSpecific GoverningPatternId: G.2 Uses: {G.Core, B.3, F.9, G.6} (penalty routing + trust/decay cues + bridges/CL + evidence path citation when used) ⊑/⊑⁺: ∅ RequiredPins/EditionPins/PolicyPins (minimum):

• GammaEpistSynthId[] (pack‑local ids of synthesis records; emitted iff fusion/substitution is asserted)
• EvidenceAnchorRef[] (provenance union; evidence carriers cited by A.10 evidence-provenance paths)
• BridgeMatrixId and BridgeCardId[] (explicit object alignment references when crossing is involved)
• CL/CL^plane and Φ/Ψ/Φ_plane policy-ids when required by the cited crossing or actually used loss model (semantics and penalties → R_eff remain governed by the cited definitions)
• PathId/PathSliceId? (only when citing via G.6)

RSCRTriggerKindIds: {RSCRTriggerKindId.EvidenceSurfaceEdit, RSCRTriggerKindId.CrossingBundleEdit, RSCRTriggerKindId.ReferencePlaneEdit, RSCRTriggerKindId.PenaltyPolicyEdit, RSCRTriggerKindId.PolicyPinChange, RSCRTriggerKindId.EditionPinChange}

Notes (normative intent; duplication‑avoidant):

• The auditable synthesis record identified by GammaEpistSynthId binds: (i) provenance union, (ii) explicit object alignment refs, (iii) assurance tuple refs (via their governing definitions) for each asserted fusion/substitution. A B.1.3 Γ_epist^synth application and its returned episteme remain separate from this record.
• This extension cites the Γ‑fold, Φ, and penalty rules through G.Core and exposes the pins needed for replay. When B.3/C.2.2 supplies no justified common numerical score or loss calculation, retain the separate support, actual mapping limitations and bounded assurance conclusion; a synthesis record does not supply the missing model.
