 # Original artwork HD backlog
 
-The checked catalog contains **5,753 standalone picture frames**. The active outer HD pack supplies **1,812**; **3,941** still await a registered HD replacement. All original IDs, including unnamed/unused graphics and destroyed variants, remain required. Authored mod art is separate. The outer pack contains 1,812 reviewed originals in 765 complete sequences after current 9,060-PPM continuity. Completed Linux/Windows Stage2 packages retain 1,148 frames / 421 sequences and 45 accepted mods, with every released binary/library/manifest/data byte unchanged. The private future input is ../data/hd/registered-class-review/handoff-1812-20261012/pack/, handoff SHA `2f408e91f30ca1dde263bf2ba3e6e182514abd145f7b3743756466e7e6e85e9f`; parent alone selects a runtime update.

-Batch 1812 adds 64 terrain pictures in four complete families: 104a0 and Terrain2 originals 14–16. All 21 selected full raws and 16 complete source/native 1–4 boards were coordinator-inspected. All 9,060 current source/scaled outputs match accepted references, both source guards are false, and all 18 recursive sources are stable. No sibling promotion occurred. Corrected 10460/10470 remain future-only despite independent approval; source-rib, atlas-edge and material/detail holds remain separate. The pending snapshot has 610 independently approved unregistered pictures, including 16 with a missing-prompt gap requiring parent policy. Mixed HD/original material islands remain an accepted limitation.
+Batch1844 adds corrected 10460/10470 complete 32 after independent context review, coordinator inspection of32 full raws/eight complete source/current scale boards and whole 1844 continuity. Fourteen genuine fine-material corrections preserve source rail/mesh/ridge geometry; seven/eleven unchanged siblings and all held history remain exact. Two accepted sibling promotions preserve old mains separately. Both source-age guards are false and all 18 recursive sources stable. Mixed HD/original grain/value islands, stronger source shade relief and retained irregular mottling are accepted qualifications. The pending snapshot has 738 independently approved unregistered pictures; 16 original 12 targets retain a missing-prompt provenance gap. Whole-family source-rib, border, panel-position, lavender/ember legibility and square-finish holds remain separate.
