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.

Implement the in-game Help window as a 1:1 migration of uihelp.py's
HelpWindow (single-page: ENABLE_HELP_MULTIPAGE = 0 -> LoadDialogSinglePage).
- project/ui/help_ui.gd (new): loads the real helpwindow.py uiscript via
UiScript -> UiBuild; _relabel() resolves the <HELP_*>/<CLOSE> placeholders
(produced when UiManager has no locale callback) from the project Locale
table (en) with verbatim English fallbacks, covering the original script's
two duplicate help_02 rows (right/middle camera). open/close/toggle/is_open;
close_button -> close; ESC handled by the UiManager window stack.
- project/ui/system_menu_ui.gd: help_button changed from the placeholder toast
to close() + open_help(); adds const HelpUI, an injectable help_ui member,
_ensure_help() (lazy build, reuses the menu's ui/client/assets_root),
open_help(), toggle_help(); setup() gains an optional 6th arg (old 5-arg
callers unaffected).
- project/game_scene.gd: single elif in _unhandled_input — KEY_H without
ctrl/meta -> system_menu_ui.toggle_help() (Ctrl+H stays free for
/user_horse_ride).
- project/help_ui_test.gd (new): headless SceneTree test — helpwindow.py load,
19 verbatim help rows + taskbar labels bound and non-placeholder,
close_button text, rows() helper, close/open/toggle, ESC stack top,
SystemMenuUI.open_help() lazy build.
Tests: help_ui_test, system_menu_ui_test, gamescene_test, ui_test all PASS
(plus system_option_ui_test, char_status_ui_test). No build/ in this worktree
so C++ ctest not run (no C++ change). Real-server and visual (.sub textures)
not verified. Docs: CLIENT-GAP.md W3 row + increment 50 bullet;
