CPython opens the stdlib zip with its own stdio, so it needs a real path.
On the desktop res:// is a directory and globalize_path() is enough; in an
exported build res:// is inside the PCK, which nothing outside Godot reads.
make_stdlib_zip.py now also writes <out>.sha256
mtpython_stdlib_project copies python27.zip + .sha256 into project/
(gitignored), and both export presets' include_filter lists them, so
they enter the PCK — checked with --export-pack
extension/src/python_stdlib.{h,cpp} (Metin2Python.stdlib_path in
GDScript): reads the bytes out of the PCK, writes
user://python27.zip.part, hashes the file as written against the
shipped digest, then renames. A sandbox copy is reused only when it
matches, so a first start killed mid-copy and a zip replaced by a new
build both re-stage instead of feeding zipimport a torn file.
PythonHost::SetDefaultStdLibPath / DefaultStdLibPath() answer with that
path ($MT_PYTHON_STDLIB still wins). python_stdlib.cpp is the only unit
that knows res:// / user://; port_platform stays godot-free.
Also fixes the Windows gate, which step 3b broke: without mtpython the
MinGW build compiled UserInterface/StdAfx.h (it includes ScriptLib/StdAfx.h,
as the original PCH does). port/CMakeLists.txt excludes that header and
PythonPackModule.cpp with ScriptLib, and platform/CMakeLists.txt excludes
platform/ScriptLib/ the same way.
Not done: on-device staging. The macOS test drives the mobile path with
force_stage=true, and nothing in the app boot calls it yet — the
interpreter only starts in the process with 2V0.
gates: python_stdlib_test.gd PASS (in-place path, staging, sha256, bytes
equal res://, no .part, ZIPReader finds encodings/__init__.py, no re-copy
on a second call, corrupted copy re-staged) · macOS ctest 27/27 ·
mingw + android + ios port_platform compile clean · port_map.py check 0
errors · key leak check 8/8 none.

- Mirror the remaining non-Python 2V3 closure headers (98 more, 173 total): EffectLib,
EterGrnLib, SpeedTreeLib, SphereLib, PRTerrainLib, EterImageLib, EterBase/Poly, cipher/tea,
EterLib Grp*/IME/Input/MSWindow/StateManager, GameLib actor/map/race headers, EterPack.
- SDK shims: granny.h, SpeedTreeRT.h, imm.h, Dimm.h (the SDK MIDL header, not mirrored),
dinput/d3dx8 additions; D3D8 render-state enums, FVF macros and the COM resource hierarchy;
more Win32 GDI/handle types with layout static_asserts.
- PORT edits for MSVC-permissive code (typename, friend visibility, <algorithm>, pointer→uintptr_t)
and PRTerrainLib/StdAfx.h dropping the ScriptLib/Python include.
- port_logic links the vendored cryptopp/minilzo.
- extension/src/platform: port_platform target with 103 generated stub files (1917 function
stubs, 146 static members) from the new platform_stub.py (clang -ast-dump-filter);
MT_PLATFORM_STUB() marks every unimplemented body. libmtgodot links port_platform and
port_gate.sh builds it.
Gate: macOS, Android, iOS, Windows (mingw) PASS; Linux BLOCKED (no toolchain).
