Optional HD artwork

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 697 reviewed replacement frames in 276 complete sequences. These include all twenty-one light, dark and firing-flash player poses, 222 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, both title logos, three standalone opening cards and 128 canonical terrain tiles. The tracked playable snapshot at 26ed9cc contains 340 reviewed frames and stays unchanged until the root assembler refreshes it. The complete catalog backlog and generation status are listed in 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 697-frame snapshot passed 2,788 actual scale checks. All 3,485 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 644 ordinary sources introduce no reserved palette labels; fifty sources retain legitimate gameplay classes, and the three opening cards use their authentic static palettes. Historical smaller-pack proofs 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, selected contracted hulls and the final EBOSS6 white-plate substitution remain held and are excluded.

The six corrected dinosaur poses preserve every native source occupied cell, bound and centroid, including the formerly lost dorsal, belly and tail points. They contain new painted detail at higher scales. The restored 0x10345 fighter retains its fork teeth and lower rails; ten very dark outer corner/foot cells remain an accepted contour interpretation. TANK01 has stable hull landmarks and distinct tread phases; three or four external corner cells per pose round inward at 1× while every source cell retains occupancy at 2×–4×. Minor stationary surface shading variance is disclosed.

All eleven HUD pictures retain their complete stroke layout and holes. Corrected N7's lower gold source cell becomes copper shading, with adjacent gold and the complete lower step still readable. The warning and cursor have source-bound gallery approval; the cursor retains opaque backing, all seventeen lit positions and the original index255 center. The corrected SYSTEM DAMAGED draft and other UI controls remain separate pending review. Native bitmap fonts keep their classic artwork.

The complete light banking sequence uses matching silver/gunmetal materials, dark red accents and the seven distinct original roll poses. Its safe square crop rectangles remove transparent canvas margin without excluding any pixel with alpha at least 32. Independent Rust image::Lanczos3 checks use the runtime's two resampling stages, first to the resident 128×128 canvas and then to the original 32×32 logical size. All seven frames have source silhouette overlap of 87.7–92.3%, bounds within one logical pixel and centroid displacement below 0.74 logical pixels. Full-sequence visual review also checked the nose, canopies, wing ends and engine exits; numeric overlap alone does not approve a frame.

The first four equipment families' visible material masks overlap their originals by approximately 93–100%, and both Plasma icon frames share the same aligned alpha footprint. Their full alpha-mask overlap is lower, approximately 54–78%, because nearly black original opaque outlines become transparent around the detailed replacement. This difference is recorded separately from the visible metal silhouette. The ten newly added equipment/pickup frames have full logical-mask overlap of approximately 87.5–99.3%. Ground-defense originals and their replacements are fully opaque, which the source-aware loader accepts.

Small-scale differences remain visible. At 1×, each Plasma projectile loses one tail row: the original 8/6-pixel heights become 7/5 pixels, while 4× retains the original logical extents. The first energy effect's fine cardinal rays also contract under binary alpha at small scales; its 1× bounds become (7,5)..(34,34) against original (3,2)..(38,37). At 4× the rays remain visible but end approximately 1–2 logical pixels inside the source extremes. Later rings use smoother, thinner contours. These differences affect presentation and are follow-up candidates for per-asset fallback; source collision dimensions remain unchanged.

Generated drafts are not active coverage. Earlier player atlas attempts and shortened extreme-bank variants were rejected. The complete light family replaces the initial straight-frame proof; the dark family uses coherent lighting edits of those reviewed poses and the original dark palette. Its exact runtime logical-mask overlap is 87.3–91.4%, with centroid displacement below 0.68 pixels, bounds within one pixel and no clipped meaningful alpha. The newly added Ground Missile, Turret, Pulse Cannon and Energy Grab families preserve their source phase differences. Late Energy Grab interprets two single-pixel peripheral ring holes as filled detail; the main transparent loop remains open. The full forty-seven-frame equipment/pickup category is now registered; HUD picture glyphs remain a separate review target. A 3×3 shoreline prototype preserves the broad coastline and demonstrates the terrain renderer, but remains unregistered: repeated canonical tiles, neighbors and destroyed states need individual artwork and seam review. Original AGX cinematics retain their original artwork.

The firing family preserves all seven original poses and their localized amber reflections. Its distinct straight-frame contour points were checked explicitly: (19,8) remains opaque, (11,12) and (11,13) remain transparent, and (11,14) stays opaque. The MiniGun's four rotation phases and the seven newly registered missile phases passed complete sequence inspection; each missile retains its original exhaust length and fin layout. Native scene captures remain a separate reachability check. The additional SHIP11G1_PIC boss interprets its dark perimeter: logical alpha overlap is 82.9%, with 373 removed original occupied pixels (252 very dark) and 23 added pixels. Its towers, side machinery, center weapon and lower pods remain readable at every scale, but its alpha contour is not identical to the source.

The additional fifteen-frame bunker preserves its door apertures, gun and blink phases. Craft tread and hover-wake animations keep their distinct source poses and negative spaces. SHIP13G1_PIC has brighter detailed copper panels (mean occupied RGB about 64/47/42 becomes 82/58/52); its original copper identity and asymmetric silhouette remain readable. TARG10G1_PIC uses a reviewed subdued soil correction; the superseded orange-speckled variants remain held.

The two additional ground targets use subdued brown soil corrections; their machinery and original directions remain intact. The tiny gun sprites keep all four original gray/white patterns, and the mine keeps its pink then dark burgundy center with gold corners. These families have complete gallery review; it does not establish a placed gun or mine scene occurrence. The short Death Ray and Forward Laser beams retain exact native top anchoring, three-row heights and phase widths. Forward Laser’s high-scale bottom antialias edge can end one presentation pixel inward (4× height eleven instead of twelve), while every logical footprint remains exact. The late Death Ray crops trim only weak alpha16–27 fringe and retain all alpha≥32 pixels.

The first sixteen canonical terrain replacements passed independent review of every source/logical/4× frame, all 48 supplied mission contexts and all 755 declared cardinal neighbor pairs: 170 HD/HD and 585 HD/original. Actual native scene checks exercised all 32 cached scroll phases and content-hash/load-order invalidation. None of these sixteen IDs has a declared destroyed partner; the separate native destruction-cache proof therefore adds no HD debris coverage. The additional corrected terrain family preserves the treeless 0x20111, and the thirty-two industrial tiles preserve source roof, wall and pipe geometry. Their final compositor review covers all 66 full pages and 1,706 cases: 1,379 neighbor pairs, 234 contexts and 93 state swaps. A texture-preserving edge/corner correction removes the earlier repeating grain ridges without moving source material boundaries. These forty-eight frames are now registered. Mixed HD/original detail contrast remains visible, and foreign destroyed partners still use original fallback; their appearances in state tests do not add HD debris coverage.

The additional thirty-two terrain frames (0x10390–0x103af) preserve original grass/tree placement, cast-shadow polygons, pipe routes, rubble strips and destroyed structures. Complete independent review inspected all 61 context pages and 1,426 declared cases at scales 1–4, including the original 0x10395/0x10436 and 0x103ae/0x1045a/0x1045b state relationships. The finer soil, leaves, rubble and metal texture is visibly denser than original fallback neighbors; no shifted pipe/coast, restored wreck, hole or new edge ridge was observed. Foreign partner artwork still uses original fallback.

The next thirty-two terrain frames (0x103b0–0x103cf) passed every source/native scale and all 39 current grain-fixed context boards. Their 120 cardinal pairs and 33 full 3×3 contexts produce 612 scale cases with no palette-class drift or overlay-order difference. Source pipe, roof, soil and canal joins remain aligned without recurring grain ribs. These IDs declare no state partners, so the review adds no destroyed-partner or new Host-scroll coverage. Unremastered neighbors keep original fallback.

The new rotor and hatch-to-turret families retain every original phase; the jungle leaves stay inside the source material region. Energy pickup trajectories retain all original opaque dark backing. Death Ray equipment keeps identical housing across its four light states, with four shared peripheral alpha additions disclosed. Its duplicate pale-gold phases and the gold flash duplicate medium phases use byte-identical source/raw/runtime aliases.

Four small pilot portraits (0x10116–0x10119) passed actual SDL main-menu SD/HD captures in the new 400×225 layout at logical position (30,45). All eight captures and the comparison board were reviewed; their faces, equipment and slanted ID-card backgrounds stay recognizable, and every surrounding UI pixel was identical. The five large portraits and both title logos have complete gallery review but no verified active UI route. The Chinese logo legitimately uses 478 original fire-class pixels; its HD output preserves that class and adds no water or blink labels.

The newly reviewed effect families retain their complete phase ordering. Lightning branches are thinner and slightly cooler blue; the late AirBlast rim is thinner; PickupGlow uses a rounded interpreted contour rather than identical alpha. Actual Canvas::shade checks over original terrain confirm that pickup-mask holes preserve the background and mask RGB never paints foreground pixels. Other effects remain held where generation filled transparent holes, removed final fragments or made subdued smoke/embers too bright. A successfully decoded draft does not establish artistic approval.

Working originals, source references and generation/review drafts under ../data/ remain outside the repository. The bundled original catalog and approved HD runtime snapshot under this repository's data/ are tracked in Git, as are the bundled game, libraries and runtime manifest. Authored mod packages include their generated SD/HD PNGs, sounds and provenance in Git. The new authored menu backdrop has its own packaged rendering path and is not counted as an original catalog sprite replacement.

The sources were decoded with tools/hd_art_source.py, inspected, and passed to the built-in image_gen tool using the imagegen skill. Sources, raw generations, prompts, contact sheets, frame metadata and review notes remain in local family folders (enemies/, bosses/, effects/, equipment/, player-light/, player-dark/, and terrain/). The superseded initial straight-player proof and its exact generation prompt remain saved locally at:

• ../data/hd/light-player-straight-hd-v1.png
• ../data/hd/prompts/light-player-straight-v1.txt
• ../data/hd/provenance.json
• ../data/hd/source/light-player-straight.png

That proof PNG has real alpha transparency, is 1254×1254, and was copied unchanged from the tool's output. Its logical silhouette overlap was 92.1%, but it is no longer mapped into the active pack because the complete family now has consistent materials across all seven poses. An earlier extreme-bank attempt remains at ../data/hd/light-player-bank-0-hd-v1.png with prompts/light-player-bank-0-v1.txt; it is rejected because its footprint overlap is only 62.2% and its engine ends are shortened. Reviewed production frames and their crop metadata are in ../data/hd/player-light/. The generated PNG bytes remain unchanged.

Pack format

The following shows pack metadata; artwork paths resolve within the selected pack. The bundled approved pack and its artwork are tracked in data/hd/. This example shows one entry from the complete seven-frame light family. Decimal IDs are shown alongside their hexadecimal meaning.

{
  "format_version": 1,
  "name": "Source-aligned HD artwork",
  "description": "Optional artwork; original fallback for uncovered frames",
  "sequences": [
    {
      "name": "Light player banking",
      "base_asset": 65818,
      "frame_count": 7,

        }
      ]
    }
  ]
}

base_asset is 0x1011a; the supplied frame targets base_asset + frame, so frames never depend on filenames or glob ordering. frame_count declares the whole original animation sequence and frames explicitly declares replacement coverage. An optional crop: [x,y,width,height] selects a rectangle from a PNG atlas or aligns a generated canvas by removing only transparent margin. The current pack supplies all seven light-player entries.

Version 1 requires exact original logical canvas dimensions and the original top-left anchor [0,0]. Canvas alignment is retained even when transparent margins surround the visible image. The PNG or crop must have the same aspect ratio as the original canvas and at least twice its logical resolution. The source hash prevents artwork silently matching a changed original asset. Original sprites with transparent negative space require transparent HD artwork; fully opaque originals may retain fully opaque replacements. Duplicate IDs, invalid sequence metadata, bad paths, crop bounds and unreasonable image allocations are rejected. Paths must remain inside the pack directory, including after symlink resolution. Open D: details from the main menu to inspect rejected frames and coverage.

The original picture header's two fields before width/height are opt1 and opt2; they are not drawing origins. The audit records these as header_options. Replacement origin: [0,0] refers to the original canvas anchor and does not reinterpret those header options as sprite offsets.

The streaming runtime source-checks the complete manifest and validates each original generator-sized PNG/crop when used. It stores no more than the original logical canvas at 4× resolution, the highest supported presentation scale. Raw generated PNGs and provenance remain intact on disk. Three 32 MiB LRU caches hold decoded atlases, derived RGBA frames and palette-bound indexed sprites; eviction never removes a registered frame. A separate derived disk cache is capped at 512 MiB. The full catalog is no longer subject to a 128 MiB artwork admission limit. See hd-streaming.md for validation ceilings, cache identities and corruption handling.

Original source locations also constrain palette classes: ordinary art uses indices 0–239, water stays in 240–244, fire in 245–249, and original blink/flash labels 250–255 remain exact. New HD coverage over an originally transparent location stays ordinary. Compact source-label metadata has a separate 32 MiB ceiling and is omitted for wholly ordinary sources. This prevents static metal or equipment highlights from acquiring fire cycles or blinking merely because a generated RGB value matches an animated palette entry. The accepted frames passed all-scale checks of these reserved-index counts. Static cinematic cards use a separate palette mode with all 256 colors; source references bind Apogee, Cygnus and Taiwan cards to their authentic palettes. The three complete source-bound HD still cards are now registered. Their original titles, tagline, Traditional Chinese glyphs and line breaks were compared at all four scales; stronger nebula, star and metal highlights are disclosed. The Taiwan card has no active opening cue, so its coverage is gallery-only. These standalone pictures are distinct from preserved AGX playback.

HD frames are resampled directly to the selected presentation canvas and quantized to the game palette. They bypass ScaleNx filtering, preserve transparent pixels and use the normal layer order. Indexed output allows palette effects to apply consistently; subtle RGB shades and alpha edges are reduced by the original palette and binary sprite transparency. The validated terrain renderer overlays canonical, full-opaque HD tiles on the joined original layer. It shares HD edges and corners where source material classes agree, transitions HD/original boundaries over two logical pixels, and preserves water/fire/flash palette classes. Intact and destroyed IDs are independent targets. The renderer adds no remaster coverage by itself; each terrain family needs the same contextual review before registration.

The metadata-only completion ledger tracks every one of the 5,753 original picture IDs, including unused enemies, damaged variants, HUD graphics and unnamed terrain. It separates missing, in-progress, candidate, reviewed, registered and render-reachable stages. tools/hd_job_queue.py creates 674 disjoint picture jobs, plus 13 classic cinematic and four bitmap-font verification jobs. Original AGX artwork and sharp native glyphs have explicit preservation policies; they are never reported as AI remasters. The external ../data/hd/jobs/queues/ files assign continuous enemy, boss, equipment/UI, effect/projectile and terrain work with exact source hashes, complete animation families and neighbor/state references. Exact-payload aliases may share reviewed artwork while retaining each ID's source binding.

Workers can validate an isolated proposal with python3 tools/hd_candidate_review.py --candidate ../data/hd/jobs/JOB_ID/candidate.json. The helper hard-links raw artwork into a temporary pack, captures an immutable copy of the newest built Rust game library, and exports all scales 1–4 plus source/logical/4× contact sheets. The copy retains the exact original build timestamp and SHA-256; a concurrent Cargo rebuild cannot replace the tested artifact or make old code appear fresh. It records raw artwork hashes, library identity and build origin, rejects a changed snapshot, warns when asset-loader source is newer than the build, and pages large reviews in groups of sixteen frames to avoid an unbounded giant image. Admission rechecks the snapshot hash and source age. Every page listed in runtime-contact-sheets.json requires inspection. It never edits the active pack or generated pixels. A successful gallery still needs coordinator visual approval and separate scene/context evidence.

After explicit artistic and independent approval, the coordinator can run python3 tools/hd_register_reviewed.py --job JOB_ID --dry-run, then omit --dry-run to register the reviewed family. The command checks every original target, complete sequences, the exact approved frame bindings, all four runtime scales, the reviewed library and unchanged PNG hashes. Held artwork, stale evidence and duplicate registered IDs are rejected. It writes the complete manifest atomically and preserves provenance; registration does not claim a native scene occurrence or finish the catalog backlog.

Generation workers share a four-submission gate through tools/hd_generation_gate.py. They prepare references and save prompts before acquiring. One orchestration acquires, marks the request started, awaits built-in imagegen and reports its actual outcome immediately before returning to the model or doing local review. Started and legacy-unknown requests require explicit completion; only unstarted reservations expire. Status shows phases, ages and admissions, and supports owner recovery without cancelling tools. Connection failures retain exact sanitized text and UTC timestamps, impose a 60–600-second cooldown, and permit at most three connection failures per job in a thirty-minute retry batch. See the mandatory workflow and wrapper. Logs and gate state remain ignored.

Inspect every source frame before generating its replacement. Request the same orthographic camera, silhouette, canvas placement, orientation, material colors and lighting for every frame. Preserve the generated alpha. Do not substitute rotations of one frame for the original bank poses: compare the complete sequence at its logical size and at the intended display resolution. Verify that the nose, engine exits, wing extremes and animation pivots remain aligned and that no clipping or background halos appear.

Keep image-generation prompts and provenance alongside the artwork. Never overwrite original catalog assets. The loader deliberately accepts partial coverage so a reviewed sprite can be previewed before the complete pack is ready, while preserving per-frame fallback.
