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.

- extension/: godot-cpp submodule (master, API 4.7), Metin2Model node
registered, links xrender-poc/libgr2 via sibling-dir reference.
- project/: Godot 4.7 project — orbit camera + DirectionalLight3D (shadows)
+ WorldEnvironment/procedural sky + placeholder cube; main.gd probes the
extension and can run libgr2 on a real .gr2 (MTGODOT_PROBE_GR2).
- build.sh one-shot build into project/bin/.
- docs/GODOT-POC-PLAN.md (phased: Phase 1 macOS -> M0'/M1/M2/M2.5).
Verified on this machine:
[mtgodot] Metin2Model registered OK — libgr2 linked
probe_gr2(warrior_cheongrin.gr2) -> gr2 OK: format_version=6 sections=8
Metal Forward+ renders the scene (test/golden/m0-scaffold.png).
