//! SOURCE: observed from the pinned oracle 9.7.10 en-US output of the
//! oracle-success settings programs (`compile.workshop` settings section of
//! the committed snapshots pixelart/santa/broken-weapons/client-to-server,
//! plus the parabola/crosshair/inputhud oracle runs) at OverPy commit
//! `eea67ad`. This is observed-behavior data, not copied OverPy source
//! (LICENSE-BOUNDARY policy). Additions to the table (e.g. the acquired
