026-G04 Owner closeout

Owner decision: PASS_WITH_LIMITATIONS for the bounded branch-local G04 scope. This document does not mutate the shared gate matrix; global status consolidation remains a multi-agent integration action.

Requirement	Evidence	Decision	Limitation
G04-LIN-001	L2/L3	SATISFIED_BOUNDED	Executed dispatch combinations only; no DISCRETE claim.
G04-LIN-002	L2/L3	SATISFIED_BOUNDED	Patch/invariant evidence only where applicable; no universal patch claim.
G04-LIN-003	L2	SATISFIED	Executed supported nodal/distributed cases and approved residual/equilibrium policies.
G04-LIN-004	L2	SATISFIED_BOUNDED	Isotropic routes bounded; orthotropic/laminate extensions remain non-qualified.
G04-LIN-005	L2	DEFERRED_LIMITATION	HEX8 four-level series passes; broader family quality/distortion evidence remains limited.
G04-LIN-006	L2	SATISFIED	Six invalid-input contracts reject fail-closed and deterministically.
G04-LIN-007	L0_EXTERNAL_UNAVAILABLE	DEFERRED_LIMITATION	Code_Aster/CalculiX unavailable; future external campaign required before external-correlation release claims.
G04-LIN-008	L2	SATISFIED	Branch-local provenance is complete; global consolidation is deferred.

Bounded qualification scope

The decision qualifies only the tested and supported combinations of linear_static, small-displacement linear elasticity, and the existing beam_isotropic, shell_isotropic, and isotropic_3d routes across BEAM2, MITC3/MITC3+, MITC4, TET4, TET10, HEX8, and HEX20. It does not generalize to untested element/material/load/BC combinations. DISCRETE is NOT_APPLICABLE; the existing RBE2 case is DIAGNOSTIC_ONLY.

No external result is PASS: both tools are SKIPPED_UNAVAILABLE. G04-LIN-007 is therefore a deferred limitation for 0.2.6 and a required future campaign before release claims include external correlation.

No solver, formulation, nonlinear, TL, G07, Agent A, or global gate file was modified.
