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.

step 3a — 标准库:
tools/py_embed/make_stdlib_zip.py packs the vendored Lib/ into
<build>/python27.zip (397 modules, 6876547 bytes, ZIP_STORED — the zlib
module is trimmed out of our CPython, so zipimport cannot inflate).
The mtpython_stdlib target builds it; py_embed_test and the launcher test
both run against it.
platform/ScriptLib/PythonHost sets the embedding flags before
Py_Initialize and, after it, puts the zip on sys.path and re-registers
encodings.search_function with codecs — 2.7 builds the codec registry
once, at startup, so replacing sys.path afterwards needs it back.
step 3b — pack 模块:
UserInterface/PythonPackModule.cpp copied verbatim; packExist/packGet/
initpack read root/ and uiscript/ through CEterPackManager, i.e. through
asset_io. The CHINA_CRYPT_KEY block in that unit is CAccountConnector's
and is kept #if 0 until the login slice (2V1). UserInterface/StdAfx.h is
a documented partial mirror — the original is the whole client's PCH.
The launcher test now runs initpack() as RunMainScript does (its first
line), reads system.py / uiscript / locale text back out of the packs, and
confirms cp1252 decoding works off the zip. system.py still stops at
"No module named app" — the C++ modules are the 2V0 slice.
gates: port_map.py check 0 errors · key leak check 8/8 none · macOS ctest
27/27 · android + ios port_platform compile clean.

The embedded 40250 script layer needs its own interpreter on five platforms.
2.7 is end-of-life, so nothing can be fetched from the target SDKs and the
source is vendored (official 2.7.18 tarball, trimmed to 25MB; Lib/ stays for
step 3's python27.zip).
cpython-2.7.18/CMakeLists.txt builds one `mtpython` static library from exactly
the 133 objects the reference libpython2.7.a contains, off by default behind
-DMTGODOT_EMBED_PYTHON=ON. The source list and the built-in module table
(config/config.c, 39 entries) are shared; pyconfig.h is a probe result and is
not, so each platform keeps its own under config/<platform>/, regenerated by
tools/py_embed/gen_pyconfig.sh and checked against the shared table.
Three vendor patches, documented in docs/THIRD-PARTY.md: configure/configure.ac
learn arm64 on macOS, and posixmodule.c undefines the process-control calls it
hard-defines past pyconfig.h when building for iOS.
macOS (ctest python.embed: every builtin imports, codecs and pickle work off the
vendored Lib/), Android arm64 and iOS arm64 build. Linux needs a Linux host and
Windows needs a MinGW-vs-MSVC decision; both are noted for step 4.

tools/asset_manifest.py records path/size/sha256 of pack/Index, every .eix/.epk
and Eternexus/root/*.msm (audit/assets/40250-client.json). The gate script sets
MT_ASSETS_STRICT=1, verifies the manifest, runs the native pack/proto tests and
four Godot tests, and fails on a missing client, a mismatch or a skip.
MT_40250_CLIENT now comes from the environment for the native tests too.
remote_player_test accepts both weighted WAIT variants (wait/wait_1).
PORT-PLAN §5 records the 2D status.

Read-only scanner for Client/pack following PackInitialize -> CEterPackManager
-> CEterPack::__BuildIndex/Get2. Keys are read from the reference EterPack.cpp
at run time; none are stored. Pure-Python TEA + LZO1X.
- 136 registered packs, 54,891 entries: NONE/COMPRESS/SECURITY only, no
PANAMA/HybridCrypt, all entries decode
- first-registered pack wins; 2,282 shadowed entries (2,194 differ)
- metin2_patch_{sd,mineral,mundi} use a second packer layout; 4 SECURITY
files fail 40250's CRC check and never load in the original
- no case collisions; paths are already lowercase
- PORT-PLAN: read EPK on device via ported EterPack, base install minus
extra locales, rebuild dict in Index order on any pack change

libpython2.7.a cross-builds with NDK 27.2 (API 24) after disabling
HAVE_LANGINFO_H; 30 C modules built in. On a OnePlus 13 (API 36) the
harness runs system.py -> prototype.RunApp() and imports the root modules
with results identical to macOS (66/74; the 8 failures are stub values or
dev-only scripts). py_embed_spike.py now isolates __main__ like
CPythonLauncher and reports stdlib usage.
