-The external and assembled shared runtime pack contains **5,323 reviewed original picture frames / 3,502 complete sequences**, including **4,235 Terrain pictures**. **430 of 5,753 original pictures remain**: 300 Terrain, 87 enemies/ground objects, 36 UI/other and seven bosses. The new 91 complete native singletons comprise the 88-picture terrain batch, 200b2 and Late tiles 30432/30443; all generated PNGs and literal native sampling fields remain unchanged. Every earlier 5,232 binding and full 3,411-header prefix remain exact. The assembled data contains **9,313 files / 8,124,102,872 bytes**. CLI validation passed all 5,323 frames with zero rejects and 45 mods / one override. Published 5,232 and its exact native Windows success are confirmed; 5,323 publication/native Windows remain pending at this freeze. All 4,666 endpoint context/control cases have actual independent decisions; all 1,481 Source witnesses and 1,374 ordered groups have deterministic data/approved-endpoint validation. Actual manual pair comparisons remain separately named, including both 116-pair ranges. The 29 historical retained aliases carry explicit old-epoch/RGB-only/native4-control limits, with no provenance or current8ada joined-equality upgrade. Fine grain, texture/value-density islands, native1 softness, joined Source-class remaps and the accepted contour/cue limits remain qualifications.

 Preserved earlier 14 October 2026 document-freeze observation: The external and assembled shared runtime pack contains **5,232 reviewed original picture frames / 3,411 complete sequences**, including **4,145 Terrain pictures**. **521 of 5,753 original pictures remain**: 390 Terrain, 88 enemies/ground objects, 36 UI/other and seven bosses. New 10544 and 20650 are complete source-native singletons with unchanged generated PNGs and default sampling; crop and optional cue/coverage fields remain absent. Every earlier 5,230 binding and the full 3,409-header prefix remain exact. Separate source/material and context reviews preserve contour, native1 softness, finer grain, olive brightness and mixed Original/HD value-density qualifications. Their actual current8ada context outputs remain at 5,229 and are carried by distinct complete Source/input equality against 5,230; no new raster is claimed. The assembled data contains **9,240 files / 7,879,384,961 bytes**. CLI validation passed all 5,232 frames with zero rejects and 45 mods / one override. The previous 5,230 publication is remote-confirmed and its exact native Windows workflow passed. The 5,232 publication and its native Windows completion remain pending at this freeze. The separate 88-picture batch remains outside admission. All 4,666 endpoint cases now have independent context/control decisions; genuine Source order and deterministic state-pair validation are recorded separately from actual manual paired comparisons. Adding these two pictures changes none of its 4,932 ordered Source vectors, including fallback slots.

 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 catalog also contains **303 AGX cinematic delta frames in 13 sequences** and **4 bitmap fonts**. These have explicit native-art preservation policies: keep the classic cinematics and sharp original glyphs, validate complete playback/alignment, and never count them as generated HD replacements. The AGX frames are separate from standalone pictures.

+Canonical proof `bfaec4d308861a92dbfe0ad1f6d3cdf3cc92b1c86c63029333ee94f0831f89d4` binds the real private5 Root writer, different I5 code review and Iron3 final audit. One unchanged registrar dry run and one main call add complete1 default 1054c. All five promoted files are byte-equal to the audited output; source/raw/sampling fields and every old header remain exact. The material peer qualified removal of the invented top paint connection while retaining the circle/shore/rupture. Shorter upper brown gap, dim worn native1 stripe and fine chips remain qualifications. The different physical peer read all 13 complete neighborhoods and three comparisons of one genuine 10507→Original 10508 event at native1–4. Mixed paint-width/grain joins with Original 1053e and 78 composed Source-class remaps remain explicit. That actual 5,232 scene authority carries only through the separately authenticated 5,323 Source/default/raw identity; no repeat view, timing or whole-mission credit is invented. Held 10521/1053e/10508 remain Original fallbacks.
