Project files and build receipts
Implementation snapshot · 2026-10-12 · Sources & update notes
Save CAD, editable project companions and referenced exported/build assets together when archiving work. The JSON companion alone is not a complete project backup.
| Artifact | Purpose |
|---|---|
<assembly>.truemesh-prep.json | Configuration-specific frame selections and hull settings |
<assembly>.beamng-project.json | Vehicle ownership, references, templates, mounts and parameters |
<project>.inventory.json | Last refreshed role/ownership/material inventory |
geometry.json | Exported body identity, transforms, geometry, mass/appearance observations |
material-snapshot.json | Captured mechanical properties and material provenance |
snapshot.json, review.json | Generation source identity and approved fixtures |
manifest.json | Generated exported-vehicle contract used by verification |
static_frame_build.json | Standalone frame build receipt |
pilot-verification.json | First vehicle pilot result |
study/quick-verification.json | Separate quick frame screening history |
main.materials.json | BeamNG render material definitions |
| Project ZIP and installation receipt | Packaged content and installed-copy evidence |
The exact location of a receipt depends on its workflow. Use the Log, Open Build Folder, and build manager rather than guessing the latest folder by name.
Identity and hashes
Section titled “Identity and hashes”Package identity is stable within a project. Display-name/image revisions retain the physical content and parent receipt. Importing/forking physics creates a new namespace.
Geometry, material, frame, generator and runtime hashes govern reuse. A filename remaining on disk does not prove it matches the current CAD. Modified sealed inputs block reuse or require a fresh generation.
Distinguish formats
Section titled “Distinguish formats”Workers validate the exported vehicle manifest and its version before consuming geometry or measurements.
Retention
Section titled “Retention”Passing tests can compact raw telemetry while retaining measurements, provenance and necessary images. Failed/cancelled runs retain diagnostics. A compact receipt does not imply raw samples are still available.
Detailed development evidence stays in the checkout’s local archive. Only selected illustrations and summaries are published on this site.
