Status and known limitations
Current baseline
Section titled “Current baseline”gatOS is code-complete through the major telemetry, control, HTTP, MQTT, serial, MCP, camera, audio,
display, scheduler, visual/debug, and example surfaces. The audited KSA baseline is
2026.8.5.5168; later game builds require the repository’s upgrade check before their bindings can be
called verified.
Many features still need an in-game flight pass even though their code, host tests, and transport tests are complete. This is not a missing interface. It is an honest distinction between “compiled and exercised outside a flight” and “a kitten has actually pushed the button in orbit.”
Live-validation backlog
Section titled “Live-validation backlog”| Surface | State |
|---|---|
| core VM, telemetry, controls, module integration | code complete; live checklists pending |
| display | working informally after performance/stability fixes; formal check pending |
| audio, IVA, FX, timed scheduler, camera | code complete; dedicated in-game checks pending |
| camera | first pass found a driver bug; fix landed, recheck pending |
| welds, always-render, scale, thug-life, impulse, manual RCS | code complete; flight checks pending |
| AGC mission cards and cinematic examples | host/wire checked; mission/playback cards pending |
The precise test cards, conditions, and historical upgrade notes live in
docs/VALIDATION.md.
Important limitations
Section titled “Important limitations”- Linux uses a system QEMU installation. The Windows release includes its QEMU bundle. macOS is for development, not a supported player target.
- Persistence currently has one
defaultguest disk, not an automatic disk per KSA save. - HTTP, MQTT, and 9P share snapshot/command semantics, but not every byte-oriented feature has parity: display is guest 9P only; audio upload has HTTP binary routes and no MQTT upload.
- MCP is a deliberate logical JSON API, not a leaf-for-leaf /sim mirror, and excludes display.
- HTTP, MQTT, and MCP default to
127.0.0.1; their*_bind_hostsettings can expose them to another interface. These services do not add authentication when you do so. - Camera ownership cannot take IVA or map cameras. Camera tracks also require the scheduler gate.
- A disabled RCS mode causes manual translate/rotate to do nothing; focus changes, ImGui keyboard focus, and high warp clear their latched flags.
- A disabled decoupler reports
EOPNOTSUPPinstead of pretending to fire. - SRB propellant is not a liquid tank. Read
srb/for booster grain state.
Use status/accessors when a feature that should exist returns EOPNOTSUPP; it reports the degraded
integration capability instead of leaving you to divine it from the vacuum.
