Document the patch calling convention once in lib/default.nix; patch
headers say what, target, hook, state and contracts. Comments only, no
code changes.
steamFrame.dashboard.windowCurvature: the "Toggle Curvature" row of a
window's More Options menu becomes a control (click: curved -> flat,
flat -> stock; drag up/down with the laser: curvature relative to
SteamVR's stock curve, snapping to 0 and 1). The patch moves each frame's
curvature-origin node to stock distance / value in outgoing scene graphs;
per-window values live in the systemui page. Lookups by signature
("window-curvature" in signatures.json, incl. check-only anchors).
Shared method hooks (lib/hooks.js, passed by mkPatch as 4th argument):
one SendMessage wrapper for dashboard-windows (now VERSION 3) and
window-curvature instead of a chain of per-patch wrappers; legacy
wrappers on top are unwound.
dashboard-windows: steamFrame.dashboard.windowMaxScale and
windowDistance.{world,theater,dashboard}.{min,max}, one runtime patch of the
SteamVR dashboard (systemui, 127.0.0.1:8087) that rewrites
frame-resize-scale-max and grab min/max-distance in the scene graph sent to
vrcompositor, then asks for one resend so changes apply immediately.
Registered only when an option is set. The mailbox class and the
scene-graph scheduler are found by signature (mkPatch, "dashboard-windows"
in lib/signatures.json, bundle vrwebui-systemui), so
scripts/check-signatures.mjs checks them offline too.
steamvr-debugger: steamFrame.steamvrDebugger.enable, defaulting to true when
a UI patch uses port 8087; merges VRWebHelper.DebuggerEnabled into
steamvr.vrsettings before every SteamVR start, and reverts it (only if it
set it) when turned off.
