-# Broken Bones
-
-Enable **Broken Bones** in Mods on the matching generalized-API build. A hard
-limb impact releases that joint's angular limits and the limb's animation and
-board-holding drives. The limb stays attached at its linear joint anchor.
-
-Use **Skater mods > Broken bones > Heal all injuries** to restore this mod's
-overrides. Turning off Enable injuries also heals. Map changes/unload restore
-controls. Heal on teleport is enabled by default. Normal bail recovery alone
-does not heal injuries.
-
-Settings expose impulse threshold (default 80 N s), minimum closing speed
-(3 m/s), cooldown, bail-only detection and HUD visibility. Thresholds are gameplay
-settings, not medical fracture estimates. Resting support force alone cannot
-cause an injury. Joint names and indices come from the loaded native rig.
-
-All injury logic is in `main.lua`. The host only exposes body/contact observations,
-joint and drive controls, menu actions, networking and command results. A failed
-override is reported instead of falsely marking a joint injured. Owned overrides
-are restored without clearing another mod's direct joint settings.
-
-With the mod enabled on peers, the HUD displays remote injury counts; native
-physical poses use the existing multiplayer pose stream. There are no detached
-limb meshes or blood effects. Headless Lua/native integration tests cover the
-rules and constraint controls; injury feel still needs gameplay evaluation.

-# Simon Says 2.0
-
-Enable this version on every player, using the updated game build. The host
-starts/stops from **Gamemodes > Simon Says**. Everyone races to land the called
-trick; the first confirmed clean ride-away observed by the host wins the round.
-Others lose a life. Solo plays as survival against the clock. Category filters,
-round timing, escalation, sudden death, hints and the call card remain settings.
-Eliminated and late-joining players spectate a surviving player. Stop, match end,
-world changes and unloading release the camera and player suspension.
-
-Each player acknowledges a new round before its results can count. The host
-reads replicated engine landing/bail counters and settled scoring metadata;
-there is no stick-gesture win detector or client-submitted win claim. Body spins
-are separate from board shuvit rotation. A bail during ride-away cancels credit.
-All peers need this version and the new engine observation fields.
-
-Caveman and Acid Drop guide entries are excluded from random calls because the
-current extracted scoring catalog has no distinct settled labels for them.
-The duplicate FS Fastplant card is de-duplicated. Ground tricks must finish and
-produce a confirmed scoring result; merely entering a manual/plant does not win.
-
-Start/Stop now use the game menu instead of the old ready/reset hotkeys. The
-obsolete stick-detector minimum-airtime setting has been removed.

-# Wipeout Challenge 3.1
-
-Requires the updated game build with `player_overlap` capability. Enable the
-mod, then use **Gamemodes > Wipeout**: Start, Restart at start pad, or Stop and
-return. T starts an idle run; R restarts. Each local run is a personal survival
-challenge, not a shared multiplayer race or leaderboard.
-
-Start builds the supplied four-pad sky course 40m above the saved starting
-location. Restart reuses that anchor rather than lifting another 40m. Stop and
-unload restore the original position and remove all course bodies and meshes.
-A map change removes the course without teleporting into the previous map.
-
-Hazards are persistent kinematic solids moved every fixed tick, not repeatedly
-removed/respawned static boxes. Hits use enabled native board/skater collision
-shapes through `sdk.physics.read(key).player_overlapping`. The first hazard
-entry is forgiven; the next separate entry ends the run. Sustained contact does
-not count repeatedly. One second of recovery groups simultaneous impacts.
-Water sensors and falling off the course end the run immediately. Water volumes
-extend below their original surface to catch fast falls. Timed mode clears after
-the selected waves; survival repeats them. The obsolete safe-marker settings
-were removed because they never provided a physical safe area.
