# Mil Sim asset checklist

Snapshot: 2026-09-27 (America/Denver). **286 deliverables: 16 REJECTED_FIXTURE, 5 AUTHORING, 2 STARTED_SPEC, 263 PLANNED, 0 ACCEPTED.** This includes visible assets, audio, test worlds and functional support; it is not a claim that 286 models exist.

The user requires visible runtime content made only from Gaussian splats. Authoring meshes and invisible collision proxies are allowed; visible mesh terrain, leaf cards, vehicles and effect quads are not. The user rejected all sixteen initial procedural assets for visual quality. They remain test fixtures only. Replacement vehicles require exact real variant names, sourced dimensions and verified exterior references. None is accepted as photoreal.

The machine-readable source of these rows is [asset-catalog.json](asset-catalog.json). Promote a status only when the row names actual artifacts and evidence. A generated file, an animation and a verified in-engine function are different milestones.

The playable beta has a separate [acceptance checklist](beta/BETA_CHECKLIST.md). Tank, helicopter and seat/articulation systems now have synthetic gameplay evidence; this does not promote rejected visuals or claim near-polished real-vehicle physics.

## Delivery order

1. Replace the first five vehicle fixtures with verified real variants: M1151A1 HMMWV, M1083A2 FMTV A2 6x6 cargo, M1A2 Abrams SEPv3, UH-60M Black Hawk and standard C-130J Super Hercules. JLTV A2 General Purpose is a follow-up priority.
2. Prove the Gaussian importer, independent articulated clusters, invisible collision, reset, local bundle and GPU measurement route.
3. Develop representative vegetation and ground assets for desert, arid forest, jungle and pine forest; measure dense scenes before multiplying content.
4. Build connected traversal, roads, crossings, settlement modules and logistics interactions.
5. Fill the 10 square kilometer world after visual, interaction and streaming tests pass at representative density.

## Map assumptions

The provisional map is **4,000 m x 2,500 m = 10,000,000 m² = 10 km²**. This is ten square kilometers, not a ten-kilometer-sided map. Four connected **2,000 m x 1,250 m** sectors would give each requested biome **2.5 km²**. Exact layout, species, weather and biome transitions remain design choices. The adjacency is for a demo; natural ecological realism has not been established. Full-size bounds alone do not count as a populated, functional map.

## High-resolution master and runtime quality

Preserve genuine scan/photo detail and editable masters. An 8K authoring input is a candidate for hero surfaces; 16K or multiple tiles are justified only by real source detail and close viewing distance. Extra pixels, redundant points and heavily subdivided source meshes do not prove photorealism. Keep source images, reconstruction/training method and provenance so quality can improve without rebuilding the whole library.

At runtime, export Gaussian-only near/mid/far detail or another verified progressive representation. Set point counts, per-cell residency and streaming distances from measured image error, camera motion and GPU memory. Do not ship the largest master by default. Compare fixed routes on a named GPU and driver, including cold load, warmed traversal, p50/p95/p99 frame time and peak memory. Do not install drivers as part of asset generation.

Surface material entries below are offline authoring/baking inputs. A photoreal baked splat may contain baked lighting; dynamic PBR and relighting are separate renderer capabilities that must be checked. Audio and manifests are nonvisual supporting assets.

## First batch functional briefs

- [ ] **US-VH-001 - AM General M1151A1 HMMWV (B1 reference configuration)** (us_humvee; REJECTED_FIXTURE). Verified M1151A1 exterior; independent wheels, steering and doors. Current file is only the old fixture.
- [ ] **US-VH-007 - Oshkosh M1083A2 FMTV A2 6x6 cargo truck** (us_cargo_truck; REJECTED_FIXTURE). Implement the verified modern M1083A2 identity; acquire matching exterior dimensions rather than reusing A1/A1P2 measurements. Current file is only the old fixture.
- [ ] **US-VH-017 - M1A2 Abrams SEPv3** (us_main_battle_tank; REJECTED_FIXTURE). Use a verified modern SEPv3 exterior with independent hull, turret and track clusters; do not relabel older Abrams geometry. Current file is only the old fixture.
- [ ] **US-VH-027 - Sikorsky UH-60M Black Hawk** (us_utility_helicopter; REJECTED_FIXTURE). Verified UH-60M exterior with independent rotors and doors. Current file is only the old fixture.
- [ ] **US-VH-035 - Lockheed Martin C-130J Super Hercules (standard fuselage)** (us_transport_aircraft; REJECTED_FIXTURE). Verify standard C-130J separately from stretched C-130J-30; retain independent propellers, gear, ramp and control surfaces. Current file is only the old fixture.

## Vehicle physics target

The owner requires a physics module aiming for **BeamNG-level suspension, tire/drivetrain behavior, deformable chassis, permanent damage and breakable components**, with Gaussian-only visuals. [Physics requirements and test plan](physics/PHYSICS_REQUIREMENTS.md) define staged acceptance. The source review and isolated CPU foundations are started; the existing viewer still has kinematic controls and no vehicle physics solver. Separate tire/track/flight fidelity and real vehicle calibration remain open.

- [x] Record the target, integration boundaries and free foundation review.
- [ ] Select and pin a backend after testing its actual browser/native APIs.
- [ ] Pass a synthetic suspension/deformable chassis rig against independent numeric references.
- [ ] Verify Gaussian deformation, fracture ownership and reset visually in both hosts.
- [ ] Calibrate one modern wheeled vehicle before heavy truck, tracked and aircraft expansion.
- [ ] Measure physics plus rendering in the four-biome world before claiming target FPS.

## App delivery acceptance

- [x] Runnable Windows .exe with local assets and documented GPU path. Original manager build launched on NVIDIA WebGPU; the separate 0.2 candidate-library build passed CPU/package checks and still needs live visual acceptance.
- [x] Matching web app with repeatable stress scenes and exported measurements. Matched WebGL/WebGPU browser orbit evidence is in `reports/gpu-integration/`; native download transport remains unverified.
- [ ] Complete matched adapter/resolution/count/frame-time measurements in both builds. Native seven-tank rendering was observed, but its full benchmark JSON was not retrieved.
- [x] Clearly identify rejected fixtures; rendering speed does not establish appearance acceptance. Source candidates remain visibly pending in the viewer.

## Shared acceptance checklist

- [ ] Visible runtime representation is Gaussian splats only. Supply native .gasset where supported and an explicitly documented .ply interchange export; the extension alone does not prove Gaussian attributes or importer compatibility.
- [ ] Meshes may exist as offline authoring/baking sources or invisible collision proxies only. Do not substitute visible mesh vehicles, foliage cards, billboards, terrain or effect quads.
- [ ] Record meters, world up axis, handedness, forward axis, origin, bounding box, source ownership, source hashes and conversion version. Verify actual engine coordinate and attribute conventions before import.
- [ ] Every asset needs a license/provenance record, named editable master, runtime export, preview evidence and acceptance result. First-pass procedural geometry or splat conversion is a prototype, not photoreal acceptance.
- [ ] Validate finite position/color/opacity/scale/rotation values and the renderer's supported Gaussian or spherical-harmonic schema; bound minimum and maximum scale and reject corrupt or zero-length rotations.
- [ ] Review silhouette, proportion, surface variation, holes, floating splats, seams, near-camera quality and temporal stability under at least daylight, overcast and low-angle light.
- [ ] Keep capture/source image detail separate from point count. Upscaling an image or adding redundant points does not establish additional captured detail.
- [ ] Runtime quality tiers must report point counts, file sizes, peak residency, p50/p95/p99 frame times and visible error from fixed camera routes on named hardware and driver versions.
- [ ] Do not claim photoreal, fully functional, offline-ready or integrated with Doom from successful export alone; each claim requires its own current receipt.

## Family acceptance

### vehicle

- [ ] Separate independently articulated splat clusters at real pivots: wheels, steering, suspension, doors, hatches, turret/barrel, rotors, propellers, ramp, landing gear and control surfaces as applicable.
- [ ] Keep collision and seat/attachment anchors separate from visual splat clusters; exercise full motion range for clipping, detached parts and blocked entry/exit.
- [ ] Provide game-scale handling configuration and explicit supported controls. Document simplified simulation and unimplemented behavior instead of presenting animation as full vehicle physics.
- [ ] First five require a local demonstration of drive/steer or flight control as implemented, visible articulation, reset and collision behavior; measured handling and cargo/crew acceptance follow.
- [ ] Vehicle surface inputs are offline authoring/bake data unless a relightable Gaussian material interface is verified. Do not label baked lighting as dynamic PBR.
- [ ] Exact replica status requires selected variant, sourced dimensions, multiview reference and verified proportions; current first batch remains original inspired forms.

### vehicle component

- [ ] Retain stable cluster names and pivot/anchor contracts across hosts; demonstrate the component attached to at least two compatible actors when intended for reuse.
- [ ] Each state transition must be repeatable and reversible; no orphan collision or visual splat clusters after detach/reset.

### vegetation

- [ ] Use splat-only visible foliage with near, middle and far Gaussian detail levels; never fall back to mesh leaf cards.
- [ ] Wind requires explicitly movable splat clusters or supported deformation; measure overlapping foliage transparency and sorting costs.
- [ ] Use biome-specific distributions, minimum spacing and fixed random seeds; test trunks/root grounding, player visibility and collision policy.
- [ ] Pass both still-image detail review and camera-motion review through dense vegetation; no holes or popping concealed by a single favorable view.

### terrain mesh

- [ ] Represent visible rocks, ground formations and cliff modules as Gaussian clusters; offline meshes may be used to author or generate them.
- [ ] Match neighboring surface scale/color and prevent visible cracks at placement/streaming boundaries; maintain an independent collision surface.

### material

- [ ] This is an offline material/capture input asset, not a visible runtime mesh surface or proof of a Gaussian relighting feature.
- [ ] Store native resolution, real-world coverage, color-space and channel semantics. Derive lower-resolution inputs rather than upscaling to create false detail.
- [ ] Bake/sample/train into Gaussian assets with consistent lighting assumptions; compare the exported splat appearance against the source.

### building

- [ ] Use modular Gaussian clusters for visible walls, roof and doors; preserve walkable invisible collision and unobstructed openings.
- [ ] Verify doorway, stair and interior scale with a measured player proxy; test inside/outside visibility, room seams, ceiling holes and door state transitions.
- [ ] Record interior-detail scope explicitly; exterior-only buildings must not be presented as enterable.

### infrastructure

- [ ] Visible routes, bridges, lights and utility structures are Gaussian assets; collision surfaces and navigation data remain separate.
- [ ] Drive representative light, heavy and tracked vehicles across every joining surface; test bridge width, overhead clearance and unloaded/reloaded seams.
- [ ] Use identifiable light state clusters only if supported by the renderer; baked emissive appearance does not prove emitted light.

### prop

- [ ] Provide anchors, collision policy and interaction state for usable props; label purely decorative props.
- [ ] Check expected carry/lift/tow behavior against vehicle interfaces and stable identifiers; do not embed unsupported gameplay claims.

### vfx

- [ ] Use Gaussian-native clusters or renderer-supported splat attributes for visible effects. Mark unsupported effects blocked instead of replacing them with visible mesh quads.
- [ ] Bound lifespan, count, opacity and screen coverage; verify sorting, camera motion and spawn/despawn under concurrent vehicle stress.
- [ ] Smoke, haze, fog and rain are planned capabilities; their appearance and cost require renderer-specific acceptance.

### audio

- [ ] Use original or verified reusable recordings; record license and edit provenance for each source.
- [ ] Provide clean loops, transition samples, level consistency and spatial attenuation metadata; test distance and state changes without clipping.
- [ ] Audio files are nonvisual support assets and are not subject to the visible-splats constraint.

### world

- [ ] All visible world content uses Gaussian splats; test collision, streaming and gameplay separately from visual generation.
- [ ] Record world bounds and coordinate transforms; do not count an empty boundary mesh or sparse placement as a finished 10 square kilometer map.
- [ ] Use fixed seeds, known routes and named asset versions so visual and GPU comparisons are reproducible.
- [ ] Four starting regions are desert, arid forest, jungle and pine forest. Their adjacency is a demo design assumption, not a claim of natural ecological geography.

### system

- [ ] Document actual engine interfaces before wiring them. A sample schema or intended contract is not proof of runtime support.
- [ ] Exercise success, failure and reset paths with local evidence; preserve errors and unsupported states.
- [ ] Do not automatically install or change GPU drivers. Capture GPU/driver versions and re-run identical benchmark routes after user/team-controlled updates.

## Asset backlog

Priority meanings: P0: First proof and repeatable local testing; P1: American vehicle library; P2: Reusable vehicle parts and all four natural biomes; P3: Settlement detail, atmosphere and interaction expansion.

Each row remains unchecked until evidence-backed acceptance. STARTED_SPEC means that reference and acceptance planning has begun, not that the runtime asset passed.

## Reference and acquisition boundary

Primary-source references and current CC0 limits are recorded in [../sources/REFERENCE_AND_LICENSE_REGISTER.md](../sources/REFERENCE_AND_LICENSE_REGISTER.md). No third-party model, image, texture, sound or scan was downloaded by this catalog task. Manufacturer media is reference-only until individual rights are established. Terrain candidates are leads, not acquired/accepted assets.

The C-130 fact sheet contains suspect unit conversions; do not copy its numerical fields blindly. The Army Abrams PDF was available in search excerpts but the direct fetch failed. Neither is being used as a verified engineering specification here.

## Environment source work started

Eleven original offline builders now exist in [../sources/environment.mjs](../sources/environment.mjs): pine, jungle and arid trees, desert shrub, grass, fern, rocks and one ground tile per biome. The mapped catalog rows are AUTHORING. [environment-source-check.json](environment-source-check.json) confirms deterministic finite source geometry, tree triangle limits and flat tile borders. They remain generic approximations; source construction does not establish Gaussian export, photorealism, biological species accuracy or runtime performance. Their leaf surfaces are offline sampling inputs only.

## Status maintenance

When work changes, update the matching JSON asset's production_status, implementation_status, artifacts, evidence and date, then update this checklist and the workspace changelog. Keep incomplete checks visible. The first five concepts can progress independently; acceptance of one does not imply all vehicles, all biomes or the full map passed.
