[125hz]

The work from 2026-10-25 to 10-28 on 8 GB and 12 GB iPhones, on top of current main. Every behaviour change has a madeira.cfg or env switch, listed in the settings catalog.

Depends on the component PRs it pins:

• wine 3c38f40e, in iOS: runtime fixes (bcrypt, explorer, APC busy queue, atoms, mitigation policy), service manager on demand, guest log redaction, registry Fonts values wine#69
• FEX 38f34e84, in iOS: rpmalloc spans and lock sleep, WOW64 hot SMC pages, AVX without AVX2, sub-floor windows, preloaded images FEX#37
• dxmt e0abd4d1, in winemetal: pipeline archive, frame-time marks, donated RAM in the video budget (opt-in) dxmt#53
• madeira-dock 67780ba9, in Launch: service manager for the game session when the prefix needs one; hold while the game's tree still starts madeira-dock#8

Each of those is a short series directly on its current branch tip, so it merges as a fast-forward and these pins stay valid.

What's in it

• Swap tier. The MadeiraMemoryHost extension's donor pool is the tier's first stage. 32-bit programs take donor RAM, never the file. Churn, browser and whole-reservation rules each have a switch in the catalog.
• D3D12. pso-async and pso-archive (both default 0) and an opt-in video-budget trim.
• Engine fixes across memory, exceptions, WoW64, win32u and D3D12, each behind its own switch.
• App.
  • A performance overlay on the system material, with a frame-time graph and lows.
  • HID mode keeps other pads on XInput.
  • Recommended lists for a publisher launcher and its installer, two titles' editions, and community-tested Steam titles.
  • The Visual C++ runtime step in setup and Settings (MADEIRA_VCREDIST).
• Big Picture. The code for Valve's client in Big Picture (from its own folder, in the Wine desktop) is included so it can be worked on, but it isn't ready for normal use, so the library button and card are compiled out of every build that doesn't set the Swift condition MADEIRA_BIG_PICTURE_UI. No IPA build sets it (release IPAs use the Debug configuration, so #if DEBUG couldn't gate it), and no madeira.cfg switch brings it back. To work on it, build with SWIFT_ACTIVE_COMPILATION_CONDITIONS='$(inherited) MADEIRA_BIG_PICTURE_UI'.
• Dock. The game session's service manager when the prefix registers a launcher's own service, and the host's hold while a launcher restarts (MADEIRA_DOCK_GAME_SCM, MADEIRA_DOCK_KEEP_ALIVE). tools/build-ipa.sh builds dockhost.exe.
• Signing. Madeira's own signing refresh is off by default (env.MADEIRA_SIGNING_REFRESH).

On main's wave 5, some of our changes give way to main's equivalents:

• the [stp-split] store;
• the [anon-ldadd] and in-handler [anon-cas] emulation;
• MADEIRA_TLS_CLEAR_OWN_PROCESS.

The opt-in MADEIRA_ANON_CAS_FLUSH handoff stays, as its own case before main's CAS emulation. kernelbase, d3d12, madeira_d3d12, d3d12core, xtajit64 and xtajit are rebuilt from these pins; d3d9 is main's.

Review notes

• 9cd65a50-equivalent (the first commit) is one squash of the 10-25 to 10-28 fork work. I didn't split it by area here because the areas share the catalog, virtual_ios.c, Library.swift and the project file.
• The follow-up PR (stacked on this one) and Epic games: launcher ownership, store identity, installer services, thread reaping and the registry font list #515 continue from it.
• The fully combined, conflict-resolved stack is on 125hz:wave6-integration. That's what the test IPA was built from.

Tests

Host tests (tests/host/check-*.py, 180 s each) on Linux, with no Swift, Xcode or plutil and without the submodule sources checked out:

Tree	Pass	Fail
main (c2c1b03a)	132 of 204	72
this stack (125hz:wave6-integration)	193 of 251	58

• Every failure left on this stack also fails on main, for the same environment reasons: no swiftc/xcrun/plutil, the wine/FEX/dxmt sources not checked out, or macOS-only C builds. The one exception is the new check-pso-archive, which also needs the dxmt sources.
• check-config-catalog fails on main the same way ("ConfigCatalog.generated.swift is out of date"). Its generator reads the submodule sources.
• These pass here and fail on main: check-child-ntdll-alias, check-dock-contract, check-inet-poll-cache, check-lazy-windows, check-lean-diag, check-log-redaction, check-pool-low, check-sc-ipc-split, check-sc-render-loop, check-section-abort, check-small-va-band, check-steam-games, check-steam-library, check-swap-images, check-x18-arith.
• macOS CI still has to run the Swift checks (--require-swift).

Device: the IPA built from wave6-integration is with testers on 8 GB and 12 GB iPhones now.
