 # Original artwork HD backlog
 
-Current artwork/runtime checkpoint — 17 October 2026: the registered and assembled pack contains **5,413 frames / 3,577 complete sequences**, including **4,300 Terrain pictures**. **340 originals await approval**: 235 Terrain, 71 enemies/ground objects, 33 UI/other and one boss. This count includes held drafts and actual refusals, rather than only never-generated pictures. The append adds intact buildings 20273/20275 and the complete four-frame SHIP23G2 family, 200dd–200e0, in three native sequences and three raw routes (6,724,550 bytes). The four SHIP hybrids retain 98/84/120/118 Original logical cells (420 total); these cells are not newly generated HD. All previous 5,407 bindings and the complete 3,574-header prefix remain exact. Actual data contains **9,359 files / 8,252,150,324 bytes**; actual CLI validates 5,413 frames with zero rejects and 45 mods/one override (`ff0d8164`). Source18 and both Source C+D executables remain unchanged. Finite context/input reviews cover 15 saved building contexts and four genuinely observed living SHIP poses at all native scales; neither group's new IDs occur in the other's saved Source set. Gray steps, partial edges, value/grain differences and low native1 contrast remain qualified; these observations establish no universal placement, visible overlap, full-route/death or seamlessness claim. Three actual 5,413 SDL controls match their frozen controls across 6,220,800 RGB/alpha pixels; none contains the new six pictures, so these fixtures add no target-art approval. The extra S2W7 starter smoke ended in a death cinematic and supplies no passing target-art control. Published 5,407 is `6a3c465d`. Source-C native Windows at the 5,384-frame checkpoint `a073f73f` passed 379 tests with 26 ignored and zero failures; prior API-B evidence remains separate. The 5,407 native Windows run is still pending; 5,413 publication and native Windows execution are also pending. Existing dated Source-update and historical records below retain their scopes.
+Current artwork/runtime checkpoint — 17 October 2026: the registered and assembled pack contains **5,414 frames / 3,578 complete sequences**, including **4,300 Terrain pictures**. **339 originals await approval**: 235 Terrain, 70 enemies/ground objects, 33 UI/other and one boss. This includes held drafts and actual refusals. The sole addition is native singleton 30094/DSHP02G3_PIC, using unchanged raw `774b4296`, its 32×32 logical canvas, zero origin and crop `[58,0,1196,1196]`. Its 125 retained Original logical cells are not newly generated HD. All previous 5,413 bindings and the full 3,577-header prefix remain exact. Actual data contains **9,360 files / 8,253,893,890 bytes**; CLI validates 5,414 frames with zero rejects and 45 mods/one override (`3b9fd8c2`). The genuine context is base:enemy_2_74 ground entity 1219 at tick 921, health 55. Foreground air entity 1246 covers 2,263 of 3,750 protected samples across native1–4, leaving 1,487 exposed. This qualifies visible supports/fragments and layered placement in one occluded scene, not an unoccluded whole hull; the separate I3 whole intrinsic material review remains the hidden-body authority. Coarse matte retained patches, bright authored metal, partial footprints and three inherited extra native1 pixels remain qualified; the old 77-cell variant remains held. Source18 and both Source C+D executables are unchanged. Three actual 1080p/HD4x SDL controls match dated pre-M2 H5413 across 6,220,800 RGB/alpha pixels under the current 45-mod guard. These combined M2v1.0.2 plus 30094 regression controls contain neither M2 nor 30094; they add no target-art or M2 gameplay approval. Native Windows at published 5,407/`6a3c465d` passed 379 tests with 26 ignored and zero failures. Later 5,413/M2-followup Windows results remain pending; 5,414 publication and native Windows execution are not yet claimed. Historical records and all-placement/full-route/death/seamlessness limits remain separate.
 
 Preserved 17 October 2026 Source-update checkpoint at 5,384 (historical coverage): Current Source C+D runtime — 17 October 2026, published `a073f73f`: HD coverage remains **5,384 frames / 3,551 sequences**, with **369 originals remaining** (260 Terrain, 75 enemies/ground objects, 33 UI/other, one boss). Both executables are rebuilt; 90 Rust / 78 Python tests, HD validation and three exact 1080p regression controls pass. Five old Rust checks remain ignored. Source C+D native Windows CI is pending; the prior `58723547` result (361 passed / 26 ignored / zero failed) is a different epoch. Earlier material, context and QA records below remain historical; this source update adds no art approval.
