G05-B Evidence Batch

Status

This document records the dedicated modal/dynamic/harmonic execution batch prepared for 026-G05. It is part of the evidence supporting the official gate, which is closed as PASS_WITH_LIMITATIONS. The bounded refinement policies were Owner-approved on 2026-08-29; external evidence and final clean-worktree provenance remain separate closeout requirements.

Executed batch

The controlled batch completed 12/12 PASS, with zero failures, blocked cases or expected failures:

Family	Target in contract	Dedicated cases executed	Pass	Variations
MOD	14	4	4	one/two modes, modulus and density sensitivity
DYN	16	4	4	two time steps, damping, tabulated transient
HAR	12	4	4	off-resonance, refined grid, damping, modulus sensitivity

These 12 cases are a deep supplemental batch. They are not silently added to the 180-case foundation catalog, whose separate corpus contract remains unchanged.

Extended family coverage

The complete family campaign is recorded in 0_2_6_g05_family_coverage.md and its generated source of truth qualification/vnv/g05b_family_coverage/summary.json. It executes MOD 14, DYN 32 time-level cases and HAR 12 across TET4, TET10, HEX8, HEX20, BEAM2, MITC3/MITC3+, MITC4 and discrete. Every case is run through the common solve_model routes, while the resulting status remains internal prequalification rather than an automatic qualification claim.

• git diff --check: PASS;
• worktree after source commit: clean.

Open qualification items

G05B execution is complete for the added 12-case batch, and 026-G05 closeout is not recommended. The remaining items are:

1. attach the required analytical/reference and external correlations with complete provenance;
2. aggregate the case histories into a final gate decision without treating READY as QUALIFIED.

The policies in qualification/0_2_6/g05_requirements.json are now OWNER_APPROVED_BOUNDED; their scope is limited to G05 refinement decisions.
