ONE TRUTH fleet wiring

Grudge Studio uses one canonical host map. Dev Tool (doctor + Home probes) and CLI validate that rewrites return JSON, not HTML SPA fallbacks.

Full link table: Systems & APIs.

Canonical hosts

Layer	Host	Browser / app path
API base (always)	`client.grudge-studio.com`	All rewrites below
Auth	`id.grudge-studio.com`	`/api/auth/*`, `/login?redirect_uri=`
Game state SSOT	Railway `grudge-api-production-0d46`	`/api/characters`, `/api/account`, `/api/wallet`, …
Portal / ENGINE	`grudge-studio.com`	Shell only — not bag/XP SSOT
JSON catalog	`objectstore.grudge-studio.com`	`/api/objectstore/v1/*`
Live defs	`info.grudge-studio.com`	`/api/v1/*`
Binary CDN	`assets.grudge-studio.com`	GLB / tex / audio
Legion AI	`ai.grudge-studio.com`	Chat / agents · `GET /v1/context`
Account cloud	`ai.grudge-studio.com/puter-space`	Puter FS + `.puter.site` — never* bag/roster
Forge	`forge.grudge-studio.com`	Scene editor (Dev Tool Forge tab)
Coder	`coder.grudge-studio.com`	IDE (Dev Tool Coder tab)
Open	`open.grudge-studio.com`	Launcher (Preview)
GRUDOX	`grudox.grudge-studio.com`	Rooms / Carrier
Multiverse SPA	`grudge-multiverse.vercel.app`	Bermuda MP play (Preview)
Multiverse rooms	`grudge-multiverse-room-production.up.railway.app`	WS `/api/mv` only (own Railway)
Water	`water.grudge-studio.com`	Home island
Docs	grudge-warlords.github.io/grudge-dev-tool	This site
Velocity	`drive.grudge-studio.com`	Grudge City racer — not Pages Cruise
Avernus	`grudge-studio.com/avernus-arena`	Portal pit — The-ENGINE
Voxel world	`grudox.grudge-studio.com/studio/`	voxel-engine gold

Editors (three only)

Surface	Host	Role
Elite	Dev Tool local	Preview / hierarchy / save
ThreeFlow	`threeflow.vercel.app`	Warlords scene edit `?asset=`
Forge	`forge.grudge-studio.com`	R3F + Rapier deploy

Grok Builder / Pipeline / studio.grudge-studio.com are ingest or labs — not a fourth play editor.

Account → editors

Dev Tool session (Puter + Grudge ID) is the authority. Embeds get from=grudge-dev-tool&embed=1&grudgeId= plus localStorage token injection. Operators (grudachain / molochdadev / straynger) also get admin=1. Do not mint a second login per editor.

Always use https://client.grudge-studio.com as API base in CLI and Settings — not raw Railway in browser apps, not deprecated hosts.
Sign in at https://id.grudge-studio.com (Grudge ID). Puter Space is account files only.

Play binaries: assets.grudge-studio.com — GLB model/gltf-binary, PNG image/png, JS application/javascript, FBX application/octet-stream. Load Toon play bodies with loadRaceKit / gltfProdLoader (r185 Draco+Meshopt+KTX2). D1 is the asset index only.

Multiverse ≠ Metaverse. Multiverse multiplayer does not use Carrier (/api/carrier) or gameopen-production — it uses its dedicated Railway and /api/mv.

Player DB backups / sharing: Railway Postgres is the only bag/character SSOT — see Databases · sharing · backups.

Deprecated (split-brain)

api.grudge-studio.com as player or definition SSOT (legacy asset-index GET may still 200 — use ObjectStore + CDN instead)
molochdagod.github.io/ObjectStore
grudge-objectstore.pages.dev
auth.grudgestudio.com / auth.grudge-studio.com (use id.grudge-studio.com)
tactical-infinity.vercel.app (orphaned — water is water.grudge-studio.com)
Multiverse via Carrier / gameopen Railway (wrong service — use Multiverse room)
grudge-velocity.pages.dev (Houston Cruise leftover — use drive.grudge-studio.com)
arena.grudge-studio.com (use grudge-arena.grudge-studio.com)
Grok Builder as production deploy editor (use Forge)

grudge-dev doctor fails if probes return text/html for JSON routes.
