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.

proto.cpp reads the 40250 MIPX/MMPT tables with the ported CLZO/TEA (156-byte
TItemTable, 255-byte SMobTable), replacing the m2dev XChaCha20 236/335 reader.
Names follow CItemData::GetName / GetMonsterName (szLocaleName, cp1252).
GDScript callers load AssetRoot.locale_file() = pack://locale/en/<name>, which
makes the EterPack chain runtime-reachable; port-map entries for the functions
a coverage run hit move to PORTED/ADAPTED.

D3DXVECTOR2/3/4, D3DXMATRIX, D3DXQUATERNION, D3DXPLANE, D3DXCOLOR with
d3dx8math.inl operator semantics, plus the D3DX* functions the 2V3 slice
logic uses. Covered by port.common; port_gate passes on macOS, Android,
iOS and Windows (mingw).

CLIENT-GAP-FIX §2.1/§2.3/§2.4/§2.5 (+ §2.2 steps 4-5):
- §2.1 two-layer model: EntityStore is data-only. Entries are created only by
mut_spawn / mut_spawn_full / mut_spawn_main and removed only by mut_despawn /
main-vid table clear. Every other mut_* now does find-or-return with a
MT_NET_TRACE-gated debug log; no pending / replay buffer. Visibility moves to
net_world.gd::_update_visibility() — per frame it walks client.get_entities()
and mirrors is_main / AFFECT_SHOW_ALWAYS(bit 7) / IsWall(14201-14204) /
planar-distance < CHAR_STAGE_VIEW_BOUND (200*100 cm), building a node on entry
and fading + freeing it past +10 while keeping the data row (_fading guard).
Gate is fail-open when the data layer is not queryable (no get_entities /
_main_vid == 0 / no pos_cm) so existing fake-client tests are unaffected.
- §2.3 one overwrite rule: mut_spawn_full() does a clean whole-row value replace
(m_ents[vid] = e), no preservation of prior move state on VID reuse; mut_spawn()
now delegates to it. net_world._on_spawn destroys + recreates a node when the
vid already has one; mount/dismount rebuild keeps the old global_position.
- §2.4 points bounds: mut_set_points() clamps counts > POINT_MAX_NUM (255) and
zeroes the tail of a short snapshot; mut_set_point() rejects type >= 255.
- §2.5 field apply order + affect flags: new EntityStore::mut_affect_flags(vid,
lo, hi) assembles v = lo | (hi << 32) and queues a dirty tick; mut_char_update
guild/alignment/pk changes now also push Info. net_world._apply_field_updates()
applies fields in the reference call order (NetworkActorManager.cpp:470).
- §2.2 steps 4-5: mut_char_info() / mut_shop_sign() drop the touch()-creates-
entity path. Steps 1-3 (m_pending_actor two-packet merge) remain W1-owned.
Tests: ./build.sh Debug exit 0; ctest 16/16 (net.entity_store gains a §2.1
data-layer assertion block). New project/net_world_vis_test.gd for scene-node
visibility. GDScript regressions green: netbridge_test, gamescene_test,
netplay_test, p9_test, combat_fx_test, player_motion_test, net_world_vis_test.
Follow-up for W1: call mut_affect_flags(vid, affect_flag[0], affect_flag[1])
from classic_parser.cpp after GC_CHARACTER_ADD[2] / GC_CHARACTER_UPDATE
(mut_char_update has no affect param). wire_classic.h already has the wanted
static_assert on GCPoints.points.

§1.5 CG_CLIENT_VERSION: send_client_version() now branches on locale. EUROPE
(this project's locale) sends CGClientVersion2 (header 0xf1, 67B, timestamp
"1215955205"); non-EUROPE sends CGClientVersion (0xfd) + CMake-injected
MT_BUILD_TIMESTAMP in C __TIMESTAMP__ form. New ClassicSession::set_executable_name()
(default "metin2.bin"; TODO(W0): M2Client passes OS::get_executable_path().get_file()).
m_version_sent set only after send_fixed() succeeds. wire_classic.h gains
CGClientVersion2 + size-table entry.
§1.10 fixed-length text: new extension/src/net/text_codec.h — to_wire()/
from_wire_str() apply a hard byte cap without splitting a UTF-8 multibyte
sequence; godot::String overloads are __has_include-guarded so mtnet stays
godot-free. classic_session.cpp routes 8 fixed-length name/sign/comment fills
through to_wire(); parser reads GC_CHAR_ADDITIONAL_INFO name via from_wire_str().
New net_text_codec_test (ctest net.text_codec). Locale codepage (CP949/CP1252)
transcoding remains a follow-up; wire bytes are currently UTF-8 (ASCII round-trips).
§2.2 two-packet PC/NPC merge: ClassicParser GC_CHARACTER_ADD drops invisible
races (20025/20038/20039); PC/NPC only stash a bare Entity into m_pending_actor;
everything else spawns immediately with a name from root/npclist.txt (new
npc_names.h + set_npclist_path(); $MT_ASSETS/$M2_ASSETS fallback; TODO(W0):
M2Client passes the asset root). GC_CHAR_ADDITIONAL_INFO with no pending entry
records m_last_error + m_unhandled_headers and drops (never half-creates);
on a hit it merges the pending Entity with the additional-info's 9 fields into
one mut_spawn_full() then erases the pending entry. New pending_actor_count()
test hook; net_classic_session_test updated (version assertions -> 0xf1;
stash -> merge -> spawn, immediate monster spawn, invisible-race drop,
no-pending additional-info is a no-op). Depends on W2 §2.2 steps 4-5
(entity_store mut_char_info touch / mut_shop_sign cleanup) — the merge works
with current W2 code as-is.
Build + ctest 17/17 (16 + net.text_codec); netbridge_test, p10_test green.
