§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.
