In short

Eleven host checks fail on main (5fda6a0). In ten of them, production code changed after the check was written (waves 6 to 8 and the merges after them). The eleventh, check-vcrt-arm64-key, is broken by a compiler optimisation. This updates only checks under tests/host; no app, runtime or build code changes.

Details

check	what changed in production	the check now
background-run	1dbd877 added the suspended mark as a second line of madeira_audio_background's start condition; 0a2e6ed's render callback also bumps cb_epoch in its paused branch	anchors the two-line condition (and asserts the suspended gate); takes the last cb_epoch
d3d9-older-nvidia	9145c13 rewrote the Compatibility row as compatLabel("Older NVIDIA card (Direct3D 9)", …); 04dda6d, merged after it, expected compatLabel(L(…	accepts either form
epic-games, itch-store	the Other games filter gained $0.listedInLibrary (0a2e6ed) and $0.gogProductID (fc5e7cb, GOG store) between the conditions the checks looked for	look for the Epic and itch.io conditions on their own
hardware-input	pSetCursorPos reports through winios_direct_cursor_warp when the app has it (0a2e6ed)	the regex follows the warp/else branches
library-groups	the Group by rules call L() (04dda6d)	the harness defines L(), as check-frontend.py and check-runtime-settings.py do
pointer-capture	the capture methods read Self.hiddenCursorAbsolute (#510)	the fixture declares it, off
steam-library	7a158d4 declares the audio background mode and takes the grace period through BackgroundRun.shared.beginTask (check-background-run.py requires both)	accepts audio as the only background mode and looks for BackgroundRun's task
vis-trace	four lists were added since the count of 73	requires a config for every GameRecommendation
game-recommendations	c998a06's Garry's Mod check also expected hl2.exe to name the game; the list matches App ID 4000, the GarrysMod folder and gmod.exe, as that commit says, and hl2.exe is also Half-Life 2's program	drops the hl2.exe clause (App ID and folder cover both branches)
vcrt-arm64-key	(no production change) clang 21 at -O1 turns the harness's init_unicode_string loop into libc wcslen, which counts 4-byte characters despite -fshort-wchar, so the fake registry created 14 keys instead of 2	builds the harness with -fno-builtin, as check-hidpad.py does (separate commit, so it can be dropped)

Validation

Linux (Ubuntu 22.04 on WSL2), Swift 6.4.1 toolchain (clang 21), gcc 11, Python 3.10, submodules at the pinned commits.

• Each of the 11 checks fails on 5fda6a0 and passes with this branch. The first failing commit of each was found by bisecting main's first-parent history.
• Each changed check still fails when the production rule it guards is broken on purpose (12 mutations, e.g. the suspended gate removed, mute moved after cb_epoch, itch.io/Epic dropped from the Other games filter, the warp's else removed, a second background mode added, Garry's Mod's program removed).
• check-epic-games and check-steam-library still stop on Linux in parts this PR does not touch (Apple's Compression module, Python 3.14 compression.zstd); their static checks pass now.
• Full host-check run: 248 of 281 pass on main, 258 of 281 on this branch, and no check that passed before fails. The rest are Mac-only (xcrun, Darwin/CryptoKit/Compression, -fobjc-arc, mach, TSan with libdispatch, wine/build-macos), plus check-config-catalog and check-depot-overlap.
• Merges cleanly with draft iPhone Duo support, DOOM Eternal on Vulkan, and JIT and library fixes #506, the only open PR that touches one of these files. No device test needed (tests only).

AI assistance: prepared with Claude (Claude Code); I reviewed the change and ran the checks. Signed off (DCO).
