 The industrial destroyed cohort retains surviving straight gray frame segments, source dark scorch/rubble routing and warm original flecks. Brighter crack/rubble detail and fallback grain contrast are disclosed. Four other gray-remnant failures in the preceding3010d–3011c family remain held, with no partial-family admission. Terrain10410–1041f preserves original intact/damaged panel geometry, separate rock groups and stippled crossing rhythm. Authentic new destroyed targets10410/12/14 and whole-family state proof are bound; foreign partners remain original. Its rough chipped1041f material and2/3 palette blockiness remain accepted differences. The historical10400 family hold on rectangular organic-ground panels in10406 is preserved; a genuine rounded organic sibling has since passed complete independent review and remains outside the frozen runtime.

The immutable preparation journal is ../data/hd/registered-class-review/later-approved-68-ready.json, SHA fbefe59fe55510be3d6e72180f35879c839a67994632d36589c24d50e6a8f871. All 340 source/scaled PPMs match independently accepted references. These frames remain unregistered and outside the 1,148 release input; combined 1,216 proof has not been performed. Each actual library/source epoch and its literal age flags remains bound separately. Terrain10420 preserves path bends, stone groups and soil/gravel divisions; all 609 cardinal pairs and 48 native scenes have independent review with corrected complete-scene presentation. Mixed original-fallback detail density and zero new destroyed art remain explicit. The 23 shop icons remain a diagnostic under correction, including a confirmed monitor lower-support geometry hold.
 
 The lower bush40179/7a is now independently reviewed in the target scope and admitted with source organic outlines/shadows, completing the previously context-only four-cell object. The cliff and ground cohort preserves slope directions, rock positions and original brown/orange region boundaries. Its genuine no-gridv2 raw is the accepted binding; rejected gridlinedv1 remains preserved. Six unused IDs remain gallery-only; the selected40178 scene is authentic source-layout supporting evidence, while independently repeated liveHost or whole-map seamlessness is not claimed.
