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.
- Implement 10 Poison and Bone skills (Teeth 67, Bone Armor 68, Poison Dagger 73,
Corpse Explosion 74, Bone Wall 78, Poison Explosion 83, Bone Spear 84, Bone Prison 88,
Poison Nova 92, Bone Spirit 93) per 1.13c ground truth.
- Decouple damage formulas into standalone exported functions: calculateTeethDamage,
calculateBoneArmorCapacity, calculatePoisonDaggerDamage, calculateCorpseExplosionDamage,
calculateBoneWallStats, calculatePoisonExplosionDamage, calculateBoneSpearDamage,
calculateBonePrisonStats, calculatePoisonNovaDamage, calculateBoneSpiritDamage.
- Preserve BATCH1_SKILLS length strictly at 38 skills.
- Enforce 2:1 isometric ground projection geometry (ISO_GROUND_ASPECT_RATIO = 0.5)
for collision, radial Poison Nova bursts (64 bolts), and trajectory kinematics.
- Implement Bone Spirit homing steering and Bone Spear piercing (collideKill = 0).
- Integrate casting lifecycle in act-scene: mana deduction, overlays, corpse consumption,
and dagger weapon requirement for Poison Dagger.
- Add comprehensive 37-test suite in tests/skills/nec/poison-bone.test.ts.
