Delete the 29 src/client files that were no longer reachable from
src/client/main.ts (launcher/play-entry, world/act-runtime, the SP scene
modules, sim/*, cull/roofs/unit-sprites/animation/char-appearance,
ground-labels, browser-mpq-source, and the dead barrels/re-export shims).
Strip the GameEngine coupling from the online HUD: HudManager no longer
binds/syncs an engine (bindEngine, syncFromEngine, switchClass,
classProfiles, grantExperience/takeDamage/heal, pickupGroundGold, ...) or
publishes window.__d2webHud/__d2webHudInstance; inventory/world-panels drop
_boundEngine; globes stop writing __d2webHud. world-renderer,
lighting-presets and ground-item-renderer keep only the online halves.
Remove demo-only exports from src/common and src/client
(DEFAULT_UNIVERSAL/SORCERESS_SKILLS, STARTER_EQUIPPED_GEAR/BAG_ITEMS,
DEFAULT_BELT_POTIONS, BeltModel.seedDefaultPotions,
createStarterProfileForClass, CLASS_DEFAULT_SKILLS). The data now lives in
tests/fixtures/demo-profile-data.ts. Tables re-exported by
src/server/world/class-starter-profiles.ts are kept.
Tests: retarget imports of re-exported helpers to their origin modules;
delete cases that only covered removed SP code; rewrite surviving
behavior against GameEngine / common data (p0-520, p0-521, p0-528,
starter-items, issue-503/506, class-switching, glacial-spike,
skill-quickbar-tooltip, monster-target-bar MonUMod). e2e-module-split now
targets src/client/main.ts instead of play-entry. Tools that imported
deleted modules are removed or trimmed (verify-renderer-lifecycle).
Split the mixed src/ and scripts/ trees into five compiler-enforced modules
aligned with the 1.13c DLL architecture, plus tools/:
- src/common/ (D2Common/Storm/D2Lang): formats, MPQ, data tables, DRLG,
items/skills/units metadata, RNG, pack contracts. No DOM/Node.
- src/netproto/ (D2Net/Bnclient/D2MCPClient): BNCS/MCP/D2GS protocol; external
code imports only src/netproto/index.ts.
- src/server/ (D2Game): authoritative simulation + LocalLoopbackAdapter.
All 23 reverse deps into client removed; no Math.random /
Date.now / performance.now.
- src/client/ (D2Client/D2Gfx/D2Win/D2Launch/D2Sound): render, UI, frontend,
audio, session, toolbar and the play.html entry.
- src/baker/ Node-only offline packers/extractors + unified `npm run bake`.
- tools/ bot, replay, unlock, verify/audit/benchmark CLIs.
play.html is now the only HTML entry; index.html, acts*.html and bnet.html
plus legacy entry glue (src/main.ts, act-scene, net-scene, lockstep src/net)
are removed.
Adds tsconfig.{common,netproto,server,client,baker}.json wired into
`npm run typecheck`, and tests/arch/boundaries.test.ts enforcing the module
boundaries with zero whitelist exceptions.
Verification: typecheck 6/6 clean; vitest 556 files / 6640 tests pass;
npm run build clean; bake --verify (136/136 levels, universal DT1s);
netproto-replay --strict 0 unknown/opaque/errors; d2-bot walk hardSnaps=0;
audit-levels 136/136; verify-play 9/9 gates at 800x600 and 1024x768.
