Fixes from the first headset sessions: Pavlov VR-style holsters, toggle grips, and a reload that takes the full process. Full guide: docs/physical-overhaul.md.

File	What it is
l4d2vr-installer-windows.exe / l4d2vr-installer-linux	Standalone installer. Finds Left 4 Dead 2, backs it up, and installs or updates the mod from the latest GitHub release. On Linux it also sets up Proton and the VR runtime. uninstall restores the game folder. Unchanged from 1.2.1.
l4d2vr-1.2.2-full.zip	Full release: the mod, both installers, the Linux server plugin and the guide. The installer falls back to the bundled mod when GitHub can't be reached.
l4d2vr-1.2.2-source.tar.gz	Source code for this release.
l4d2vr.zip	The mod by itself, for extracting into the game folder manually.
l4d2vr-server-linux.zip	Dedicated server plugin; extract into the server folder. It replaces l4d2vr_pose_server. Update it: the reload changes need this version on the server.

New in 1.2.2

• Holsters, Pavlov VR layout:
  • Hips, chest pockets and back, measured from Pavlov VR. They follow your head and stay put when you look down, so you can see what's on your chest and hips.
  • The holstered items are now drawn, and a haptic tick plays when your hand reaches one.
  • Either hand can grip at any holster: the item there comes to your hand, and what you held goes back to its own holster.
  • The spare magazine or shell pouch is on the off-hand hip.
• Toggle grips (GripToggle, on by default): a firm squeeze takes an item, the next squeeze holsters, swaps or drops it. On the Index the grip needs a real squeeze, so resting your hand doesn't count.
• Reloading, tuned to Pavlov VR per gun:
  • A reload takes the full process: a fresh magazine in, then the slide, bolt or pump. Racking alone never loads a round.
  • The release button drops one magazine; its rounds go back to your reserve.
  • Spare magazines and shells come out of the pouch the way they sit in the gun, lined up with the well in a natural reload pose.
  • Magazine slap on the AK-47, SG552 and military sniper: take a fresh magazine with the old one still in, and strike the old one out (MagazineSlapEnabled).
  • Whatever the next step needs glows with a soft, steady tint: the empty magazine, the spare, then the slide or pump.
  • A shot the server never fired (for example right after drawing) no longer asks for a rack or pump. Before, racking after a dropped last shot seemed to load a round from nowhere.
  • The two-handed grip lets go when your support hand moves 20 cm from the foregrip, so the same hand can fetch a shotgun shell.
• Melee: motion only. Guns never play the swing or bash animation; the sound and hit still happen.
• Wrist HUD: uses the game's own health bars and font with full teammate names, including long ones. Your own bar is the large one.
• Controls: right stick forward jumps, right stick down toggles crouch (StickJumpCrouch, StickCrouchToggle); the grips are only for gripping. Point at menus with either controller and click with the trigger.
• Fixes: a first aid kit drawn from the back no longer floats in front of you; picking up items by touch works again; the glow is no longer a flickering pink.
• Config: a few magazine settings are reset to the new defaults on first start (pouch reach 20 cm, magazine well 10 cm and 45°, holster haptics). Your per-gun calibrations are kept.

Tested

Online on a dedicated Linux server with the plugin, with a simulated headset and the built-in -l4d2vrselftest, using hand-driven reloads and screenshots that were reviewed:

• Full reloads on the M16, AK-47, pistol, pump and auto shotgun: running dry, dropping the magazine, inserting a fresh one, racking. Racking alone doesn't reload, and an empty gun never reloads by itself. The reload set passed 53 of 53 checks in three runs in a row.
• The AK-47 slap, and letting go of a spare with the old magazine still in.
• Held-magazine alignment on 12 guns (5° from the well).
• Holster draws, swaps and drops with either hand; grips; touch pickups; no swing or bash animation; the wrist HUD (32 of 32 checks).
• 68 C++ unit test suites pass on MSVC.

Not yet tested

• In a real headset: how the holster positions, glow, wrist HUD placement and bash threshold feel.
• The SG552 and MP5, and left-handed mode.
