Checkpoint 1,071 reviewed HD frames and preserve Stage2 handoff scopes

 The Rust Options screen includes **HD art**. It starts disabled. Enable it to use reviewed artwork from the selected data directory's `hd/hd.json`; each missing or rejected frame keeps the selected original / 2x / 3x / 4x crisp treatment. The bundled runtime uses `data/`, while development artwork and review jobs live under `../data/`. The scale setting still determines the indexed rendering resolution, and the HD toggle can be changed while paused. HD art is presentation only: simulation, collision sizes, banking positions and save content IDs stay unchanged.
 
-The development base-game pack currently supplies **1,037 reviewed replacement frames in 396 complete sequences**. These include all twenty-one light, dark and firing-flash player poses, 232 boss frames, complete vehicle families, ground defenses and opening bunkers, all forty-seven equipment and pickup pictures, projectile and effect animations, eleven HUD picture glyphs, nine pilot portraits, four difficulty portraits, both title logos, three standalone opening cards and 320 canonical terrain tiles. The tracked Linux/Windows playable snapshots contain the separately frozen 800 reviewed frames, copied by the root assembler and committed at `964ba93`. Later development approvals remain separate from this runtime checkpoint. The complete catalog backlog and generation status are listed in [hd-backlog.md](hd-backlog.md).

 Every registered frame passed the exact original source hash, logical canvas, aspect, visible alpha and path checks. Complete contact sheets were inspected at source size and the 4× presentation size; per-frame geometry metrics and review evidence remain with each family. Their logical collision sizes are unchanged. Small contours and interpreted metal detail differ. Missing artwork keeps the crisp original fallback. HD remains an opt-in preview while the remaining catalog and game screenshots are reviewed.
 
 An actual Rust `HdAssets::sprite` pass also checked all registered frames at scales 1–4 with the game palette: every output has the expected dimensions and visible pixels, and the pack reports no diagnostics. Complete 4× source/HD sheets from that runtime path were reviewed for readable projectiles, equipment alignment, banking progression and energy-ring timing stages. These sprite checks complement live gameplay captures and do not establish full-game visual completion.
 
-The current 1,037-frame development snapshot passed 4,148 actual scale checks. All 5,185 original and rendered PPMs are byte-identical to independently accepted references, with both source-age guards clear and the tested immutable library pinned by SHA and original build time. All 952 ordinary sources introduce no reserved palette labels; 82 sources retain legitimate gameplay classes, and the three opening cards use their authentic static palettes. Historical smaller-pack proofs, including the packaged 800-frame snapshot, remain separate.

 The 189 additional boss frames passed complete source/1×/4× and native 2×/3× review across 56 full families. Opaque component panels, weapon apertures and source phases remain recognizable; fine material detail and minor contour interpretations are disclosed per family. These gallery decisions do not certify complete assembled-boss joins or native encounter placement. The shortened paired bottom feet in `0x200a2`, lost painted wing/strut cells in `0x30045`, Mole's missing initial blink, other contracted hulls remain held and are excluded. The later repaired asymmetric hull, lower bridge and complete EBOSS6 phases are reviewed separately below.

 Orange sparks preserve source warm rays, separated fragments and brown fade. Stronger outlined cell edges in101ab/ad remain sparks at their actual presentation size; adjacent additions and three faint alpha16/17/19 crop specks in101a8 are accepted disclosures, with all meaningful alpha32 artwork retained. Difficulty portraits retain defining faces, glasses, visor, cigar and skull. Warmer painting and a shallow same-region helmet-tab interpretation are accepted, without an exact-hardware claim. TEXTURE10018 and both side trims retain authentic connectors, opposing rails and eight readable burgundy slots through repeated contexts. Stronger grain/edge contrast and threshold-sensitive brown highlights are accepted visual shading, without an exact red-RGB or zero-seam guarantee.
 
 LargeAir's newer v9 still remains held: repaired first/late pairs improve the earlier missing rays and rims, but middle101eb loses a connected seven-cell inner lip and101ec loses its five-cell upper shoulder, visibly changing source structure. Terrain10406 also remains held for interpreting organic ground as rigid rectangular slabs. Neither technical decoding nor opaque coverage admits those drafts.

+A further 34-frame development batch adds two complete craft singles and thirty-two terrain tiles. All 170 source/scaled PPMs match independently accepted references, and all ten complete source/native1/HD4 pages on two boards were inspected before registration. The gray structure300ac retains its upper crossbar, central inset and lower supports. Dark craft3009d retains its posts, pods, aperture and feet, with two very dark native corner losses accepted and all higher-scale source cells plus genuine252/253 cues retained.

Corrected40157 preserves the authentic short upper-left fragment and lower-left branch;4015b excludes the rejected foreign right crack and bottom rock. Coarser standalone soil against surrounding atlas gravel remains an accepted density difference. Upper foliage40172/73 retains source organic outlines and shadows with finer leaves. Its lower40179/7a partners remain original fallback in the actual160-tile review pack. Their separate complete four-HD-cell object diagnostic is context-only and does not admit those lower two. Twenty-two native contexts/eighty-two cardinal pairs produce544 current scale compositions; no state partners exist, and ten unused IDs remain gallery-only. Original-fallback contrast and future HD-neighbor re-review remain explicit.
