 # Original artwork HD backlog
 
+Current artwork/runtime checkpoint — 18 October 2026: the optional HD pack contains **5,521 reviewed pictures in 3,650 complete sequences**, including **4,369 Terrain pictures**. **232 originals still await approval**: 166 Terrain, 54 enemies and ground objects, and 12 UI/other pictures. All 249 boss pictures are reviewed; complete Original-art coverage remains unfinished.
+
+This append adds five Enemy pictures (`200bf`, `10315–10316`, `1033e–1033f`), six Terrain pictures (`203b5`, `203b6`, `203b9`, `203bb`, `20395`, `20399`), and ten UI/other pictures (`102f7`, `10126`, complete WORMLEFT `4002e–40035`). Nineteen are reproducible derived cleanups of retained generated parents; `20395` and `20399` reuse the exact reviewed Source-equivalent `203a7` artwork. Derived outputs are not untouched generator returns.
+
+The five Enemy pictures have controlled-pose reviews, not full natural-wave or current Host coverage. The four new-material Terrain pictures have 32 genuine endpoints and five ordered neighbor-event views; Root sampled four endpoints and independent review covers the finite full set. Alias `20395` has eight genuine endpoints and three ordered views of one neighbor event; `20399` remains catalogue-only. `10126` has a Source-authentic legacy ORDER template review, not an executed legacy GUI or current Rust Host screen. ICON22 and WORMLEFT have complete intrinsic/caller-absence review; no Original spawn, clock or World is invented. Literal functional Original samples and static-boundary variation retain their explicit limits and are not generated HD. All earlier material HOLDs, failed attempts and provider refusals remain attached to their original artifacts.
+
+Actual assembly contains **9,725 data files / 8,435,456,792 bytes**. The 221-file increment consists of exactly 214 new job files plus seven restored genuine historical QA JSON receipts. Old native headers, Source bindings and prior artwork bytes remain exact; restoring old receipt files is not new QA or new artwork. Private registrar attempts, including the failed first attempt before canonical writes, remain separately recorded.
+
+Actual installed validation accepts all 5,521 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 and were personally reviewed as whole screens by the operator and Root. All three PNGs and decoded RGB/alpha planes are byte-identical to actual H5500 (zero changed pixels). These fixed presentation controls do not prove that any of the 21 new pictures appeared; existing mixed texture resolutions and Source-stepped shadows remain visible.
+
+Maintained cleanup/registration tools passed 130 tests; the four ZIP-selection/relocation tests are separate. SourceF18, both binaries, Mission 2 version 1.0.3, all 45 mod packages and the nine palette opt-ins are unchanged. Earlier engine, campaign and artwork checks retain their dated scopes.
+
+Native Windows history is explicit: H5500 at `00304e25` passed 401 tests with 26 ignored, then failed HD packaging because 15 derived routes were omitted; later mod/PCM/Stage II checks were not reached. Packaging fix `6b1a2629` preserves every manifest-required data route. The exact H5500 archive-fix run39085892624 was still pending at the dated supplied observation; no success is inferred. No native Windows H5521 execution is claimed here. The [backlog](hd-backlog.md), [completion ledger](hd-completion.json) and [runtime evidence](hd-runtime-release.json) keep the exact authorities and limitations. Actual pre-push checkpoint; Git history records later publication.

 Current artwork/runtime checkpoint — 18 October 2026: the optional HD pack contains **5,500 reviewed pictures in 3,638 complete sequences**, including **4,363 Terrain pictures**. **253 originals still await approval**: 172 Terrain, 59 enemies and ground objects, and 22 UI/other pictures. All 249 boss pictures are reviewed; the full original-art backlog remains open.
 
 This append adds one boss picture (`200a2`), three Terrain pictures (`20400`, `20403`, `20406`), the complete three-frame DSHP20G3 family and the complete eight-frame WORMRITE family. All 15 published PNGs are explicitly derived scripted cleanups of retained generated parents. Their methods preserve continuous generated RGB or coherent parent texture while using Source geometry and declared functional color cues. They are not untouched generator returns.

 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.
