Project P.I.T.T. Native Linux Reference
Native Linux Reference: Steam supplies a native Linux build.
Steam supplies a native Linux build. Its configured XDG data path is different from a forced Windows build's Proton compatibility prefix.
Check the specific platform state
Check whether the running build is native before applying the Linux path. If XDG_DATA_HOME is customized, use that root; the standard fallback is ~/.local/share.

Linux (native) save configuration
The configured user-data location is $XDG_DATA_HOME/godot/app_userdata/Project P.I.T.T. This is derived from Steam's configuration, not a local restore test. The folder name ends in T without an additional trailing period.
| Field | Value |
|---|---|
| Root | LinuxXdgDataHome override; default ~/.local/share |
| Path | $XDG_DATA_HOME/godot/app_userdata/Project P.I.T.T |
| Patterns | *.save, *.save.bak, profile.cfg, settings.cfg, keybindings.cfg, locale.cfg |

A reversible diagnostic record
Keep the selected platform/runtime, input device and exact action together. If a change fails, return to the prior configuration and preserve the save backup; do not combine a file restore, a controller reset and a renderer change in one unexplained experiment.

Evidence and verification limits
Source retrieval confirms what a source says, not a new in-game replay. Patch notes retain their version; community observations retain their limitations.
