 # Original artwork HD backlog
 
+Current artwork/runtime checkpoint — 18 October 2026: **5,567 reviewed pictures in 3,686 complete sequences**, including **4,401 Terrain pictures**. **186 originals still await approval**: 134 Terrain, 50 enemies/ground objects and two UI/other pictures. All 249 boss pictures are reviewed; complete Original-art coverage remains unfinished.
+
+This append adds eight selected destroyed Terrain pictures, UI1010c/1010f, only Terrain3050a, and Terrain30112/30113/30119/3011a. Generated parents, derived cleanup and explicitly retained functional Original samples retain separate lineage. Carried registered siblings and Original fallback/held atlas cells do not count as new approved artwork. The finite intrinsic/context/caller scopes and old pixel-versus-input epochs are recorded individually in the ledger; no all-placement, full-mission, seamlessness or performance claim follows.
+
+Actual assembly contains **10,214 data files / 8,493,122,187 bytes**. The final receipt separately records 217 new job files and 17 shared evidence files. Historical QA/proof restoration is not new artwork or a new measurement. Old Source/native/provenance prefixes and prior payloads remain exact. The bundled legacy-receipt reader passed 42 actual API reads of 23 unique receipts, including two legacy absolute-path cases with external W access blocked. The source-only V1 archival-route HOLD preceded all real preflight calls; the reviewed V2 ran one actual preflight and one private registrar main with no failed real stage or automatic retry.
+
+Actual installed validation accepts all 5,567 frames with zero rejects and validates 45 mods with one override. Three fresh 1920×1080 software-SDL controls—menu, Original Sector 1 Wave 7 and Sector 3 Wave 9—each exited successfully with empty stderr. The operator and Root personally viewed all three complete screens. All PNG bytes and decoded RGB/alpha planes match actual H5552 exactly, with zero changed pixels across 6,220,800 pixels. These fixed controls do not establish that any of the 15 new pictures appeared; known mixed terrain textures and Source-stepped shadows remain visible.
+
+The maintained cleanup/registration suite passed 196 synthetic-asset tests after the reviewed legacy-receipt portability fix, including the UI helper. The earlier 180-test run is dated predecessor evidence. The Python registrar resolves authentic legacy QA paths across the supported data roots; old JSON bytes remain unchanged. SourceF18, both binaries, Mission 2 version 1.0.3 and all 45 mods are unchanged. The exact f3b30df0 H5539 native Windows run separately succeeded:401 Rust tests passed,26ignored,zero failed plus four archive tests,5539HD/zero rejects,45mods/one override and finite Unicode/gameplay/PCM checks. The exact 05a2eae9 H5552 native Windows run separately succeeded: 401 Rust tests passed, 26 ignored and zero failed, plus four archive tests; all 5,552 HD frames validated with zero rejects and 45 mods/one override. Unicode portable launcher, finite gameplay/phase/shop and 44,100 Hz stereo/SFX captures passed, with 261,804/189,658 nonzero samples. This is dated H5552 evidence, not native H5567 execution. No native Windows H5567 result is inferred. Earlier art HOLDs, actual failures, provider refusals and dated runtime checks remain intact. Actual pre-push checkpoint.

 Current artwork/runtime checkpoint — 18 October 2026: the optional HD pack contains **5,552 reviewed pictures in 3,671 complete sequences**, including **4,388 Terrain pictures**. **201 originals still await approval**: 147 Terrain, 50 enemies and ground objects, and four UI/other pictures. All 249 boss pictures are reviewed; complete Original-art coverage remains unfinished.
 
 This append adds the complete WORMDN8 family `3001e–30025`, the complete SHIP20G2 family `200c4–200c7` and quiet brown Terrain `2039b`. Their derived outputs and declared parent lineage remain distinct from untouched generator returns. SHIP20 restores 27 Original logical yellow-tip cells (0/7/13/7 across phases); those Source samples are not generated HD detail.

 The completion ledger retains `format_version: 1` with `ledger_schema: family_review_refs_v1`. Each approved asset uses a stable `coordinator_review_ref`; `family_reviews` stores the candidate/binding identities and exact full immutable external receipt once. The original 2,132 normalization reduced 53,594,880 bytes to 8,406,611 (84.31%) without changing approval or artwork. New registrations update only their own status/evidence; native preservation has a separate closed record.
