 # HD coordinator checkpoint — 17 October 2026
 
-Current artwork/runtime checkpoint — 17 October 2026: the published H5425 artwork (`4ab5f799`) contains **5,425 frames / 3,587 complete sequences**, including **4,300 Terrain pictures**. **328 originals await approval**: 235 Terrain, 59 enemies/ground objects, 33 UI/other and one boss. This includes held drafts and actual refusals. The six added families contain exactly eight frames: 1033c, 200e6, 30052, 30070–71, 30089–8a and 3009c. Their 416 retained Original logical cells are not newly generated HD. Six unchanged raw payloads add 8,827,834 bytes; all prior 5,417 bindings and the full 3,581-header/provenance prefix remain exact, including native canvases, crops and optional-field presence. Actual data contains **9,369 files / 8,267,536,572 bytes**; CLI validates 5,425 frames with zero rejects and 45 mods/one override (SourceE CLI `6c535911`). Five different context reviews cover the six families' recorded scopes. The 30070–71 complete2 has a genuine legal private validation-World scene using its authentic EnemyDef, with natural frames 0/1 at ticks 1/3 and no HP/frame edits. All 18 Original placements remain filtered: no enabled Original-map occurrence is claimed, and this is not catalog-only render approval. Offscreen twins of 200e6/3009c receive no visibility credit. Thirty directed other-target intersections are empty in the saved 48/62/49/3/21/10-ID picture-consumer sets; entire Source sets are not claimed disjoint. Material, overlap, phase, route/death and player/projectile/secondary/UI/Host limits remain. SourceE optional Original-palette support is now release-built and installed on Linux and cross-built/assembled for Windows: 106 Rust and 165 Python tests pass, with five existing Rust tests ignored. Only desktop/HD/Terrain HD Source files changed within Source18; the other 15, all artwork/data/defaults and current 341-file/45-mod/M2v1.0.2 guard remain exact. **No installed frame opts into the palette constraint.** Three actual SourceE 1080p/HD4x SDL controls measured identical PNG/RGB/alpha to SourceC at the same H5425 over 6,220,800 pixels; Root personally viewed all three complete images. This is default-path regression evidence, not opt-in-mode or target-art approval. Current Linux/Windows binaries are `c083714a`/`cb3e0414`; the compiled epoch is `2990dec2`, actual install receipts `227a75ed`/`6fc6309c`, and SDL report/strict `127760ca`/`c8aa3e5c`. [Runtime activation evidence](hd-runtime-release.json) separates SourceE from the unchanged SourceC artwork-release record. Exact H5417/`ebc52724` native Windows remains the latest closed execution proof (379 passed, 26 ignored, zero failures); H5425/`4ab5f799` SourceC CI is still in progress at this checkpoint, and Windows SourceE assembly is not native execution. All earlier artwork, context, HOLD and refusal epochs remain literal; no private constrained trial is installed by this runtime update.
+Current artwork/runtime checkpoint — 17 October 2026: the registered and assembled pack contains **5,426 frames / 3,588 complete sequences**, including **4,301 Terrain pictures**. **327 originals await approval**: 234 Terrain, 59 enemies/ground objects, 33 UI/other and one boss; remaining includes held drafts and actual refusals. This single append admits only historical `2039c`, using the untouched earlier `1f240a2f` raw (2,904,333 bytes), native32/origin0/crop[941,941,313,313], with the SourceE `original-painted-ordinary-v1` runtime palette treatment. It is not new image generation. Exactly one installed frame now opts in. Different actual SourceE all1–4 material and one genuine S2W4r8c7 whole3×3 neighborhood are qualified (`05da73dd`/`1877c853`); the muted brown remains darker/finer-grained, with a visible texture/value island at3–4. The latest corrective `4b6b` and its other15 HOLDs remain held. Prior registered20391–94 retain actualC QA and2039a retains actualB QA: those five are unchanged carry, not new SourceE measurements. All old5,425 bindings and3,587-header/provenance prefix remain exact. Actual data is **9,370 files / 8,270,452,494 bytes**; CLI validates5,426/zero rejects and45mods/one override (`872b875a`). SourceE18, both binaries and the341-file/45-mod/M2v1.0.2 guard remain unchanged. The prior H5425 SourceE activation record remains dated zero-opt-in evidence; [current runtime evidence](hd-runtime-release.json) selects the distinct5426 successor. All three actual1920×1080/HD4x SDL controls exited0 and measured identical PNG/RGB/alpha to actual SourceE H5425 over6,220,800 pixels. Root personally viewed all three complete images. Equality was measured, not a runner requirement; these controls establish no specific2039c visibility or palette-mode art approval. Latest closed native Windows is SourceC H5425/`4ab5f799`,379passed/26ignored/zero failed; SourceE/`68669fc6` CI is in progress at this checkpoint, and no H5426 native Windows execution is claimed. This appendix does not approve the whole16, general placements or seamless material. All earlier artwork, qualification, HOLD and refusal authorities retain their original epochs; H5426 publication is pending at this document freeze.
 
 Preserved 17 October 2026 Source-update checkpoint at 5,384 (historical coverage): Current Source C+D checkpoint — 17 October 2026: remote-confirmed commit `a073f73f` installs the rational atlas sampler, protected terrain joins and bounded retained-Original policy. Coverage is unchanged at **5,384 frames / 3,551 sequences**, with **369 originals remaining** (260 Terrain, 75 enemies/ground objects, 33 UI/other, one boss); data remains **9,335 files / 8,179,315,857 bytes**. Both bundled executables were rebuilt. Validation passes 90 Rust and 78 Python tests (five pre-existing Rust checks ignored), all 5,384 HD frames with zero rejects, the 6,449-entry catalog and 45 mods/one override. Three fresh 1080p API-B/C+D controls match exactly across 6,220,800 pixels. Source C+D native Windows CI remains pending; `58723547` separately passed 361 tests, with 26 ignored and zero failed. No new artwork approval or full-HD completion follows. The following pre-C records retain their original epochs.
