- the texture filter is the reference's policy — two globals, one process-wide mode, no per-texture override — registered as real CVars every sampler reads: the hardcoded trilinear + aniso 8 at five sampler sites had been read off an apitrace of an install whose `Config.wtf` set `anisotropic "16"`, a configured value taken for a default; and `trilinear` ships ON, because the registrar's `"0"` is not what a fresh install renders at — first-launch hardware detection overwrites sixteen video CVars from its hardware table, both rows a real GPU can reach set trilinear, and the reference's own `gx.log` on this machine names that row — while `anisotropic` is not among the sixteen, so anisotropy stays off
- the MSAA device clamp ran before the config was read, so a saved `gxMultisample = 8` carried from a machine that offers it still killed the render thread on one that stops at 4; the ceiling is now a property of the write itself, covering the config file, `SetCVar`, the dropdown and any writer added later — and an empty device list is no opinion, so headless runs pass through
- one line, one rounding: at a fractional display scale the per-glyph snap's f32 round-trip moved half-pixel ties by an ulp, so caps and ascenders rounded up while x-height letters stayed — the letters left the baseline, the thing the reporter photographed; the line's two anchors now round once and each glyph adds integer device-pixel offsets, so a line cannot be anything but flat at any scale, proven over 15,680 layouts — and `$WOW_DPI`'s size guard, which compared a physical request against the logical size and refused every non-1x run, now reads the unit it is denominated in
- a test that panics while holding `ENV_LOCK` no longer poisons the tests behind it — one missing knob resource had reported as twelve red tests, eleven naming the mutex and none naming the bug; there is nothing for the poison to protect, since the guard's `Drop` restores the environment during the panicking test's own unwind
