Scope: Dependencies that V3 launch depends on — Unreal Engine 5.5 LTS and
its plugins, Pixel Streaming infrastructure, middleware, generative-AI
providers (music, voice, motion, world-assets), XR SDKs, hardware peripherals,
cloud / infrastructure services, language runtimes, build tooling, and the V1
internal packages on the V3 critical path. The Tier-2 three.js fallback stack
is included here as a constrained sub-tree. Out-of-V3 dependencies are
catalogued in the whole-monorepo /DEPENDENCIES.md and
in V1/DEPENDENCIES.md. Companion docs:
V3/V3_features.md, V3/V3_TODOS.md,
V3/V3_ARCHITECTURE.md. Date: 2026-05-12
Purpose#
This file is the V3-scoped dependency contract. For each dependency it answers
three questions a reviewer needs before launch:
- What is it — one sentence on the dependency itself.
- Where does V3 use it — the V3 features or TODOS sections that need it.
- How is it wired — env vars, package paths, ports, version source.
Pinned versions live in V3/ue/V3.uproject, each plugin's *.uplugin, each
*.Build.cs, the per-platform configs in V3/ue/Config/, pnpm-workspace.yaml
(TypeScript), each Rust service's Cargo.toml, and the per-service Docker
compose files. This document references those sources of truth rather than
duplicating them.
Cross-Reference Convention#
Throughout the V3 docs, bare §N and §N.M references resolve to
V3_TODOS.md (the canonical backlog). Within this file, bare numeric
references (e.g., §3, §14) point to this document's own sections.
Explicit doc prefixes are used where ambiguity matters:
todos§40 → V3_TODOS.md §40.arch§"<anchor>" → V3_ARCHITECTURE.md by section anchor.features§"<anchor>" → V3_features.md by section anchor.v1deps§N → V1/DEPENDENCIES.md §N (where V3 reuses V1 dependencies as-is).v2deps§N → V2/V2_DEPENDENCIES.md §N (UE plugins shared with V2).

candidate. The build uses the standard Linux UE5 cook with Steam Deck detection
(gamepad / touch hybrid input mode + 720p / 40 fps default preset). Tested per
Valve's hardware compatibility guidelines pre-launch and gated by the cert task
in V3_TODOS.md § 69.
14. Generative AI — Music#
Music generation underpins Saraswati Stage. V3 uses a multi-provider strategy
with explicit licensing constraints.
| Provider / Model |
Version target |
Use case |
Licensing posture |
| Suno |
API v4+ |
Vocal + accompaniment for indie folk, hip-hop, ambient. |
Commercial license at Pro/Premier tier; full output ownership confirmed pre-launch. |
| Udio |
API v2+ |
Vocal + accompaniment for electronic, classical-crossover. |
Commercial license confirmed. |
| Stable Audio Open / 2.0 |
API + on-prem |
Ambient stems, sound-baths, devotional cells. |
OSS or commercial Stability AI license; on-prem option for compliance. |
| MusicGen (Meta) |
API + on-prem |
Backing-track gen; open-weight on-prem option. |
Open-weight; commercial use validated. |
| AudioCraft (Meta) |
API + on-prem |
Backing + sound-effect gen. |
Open-weight; commercial use validated. |
| Mubert |
API |
Royalty-free ambient stems for low-stakes Commons ambient. |
Commercial subscription. |
| Custom in-house model |
self-hosted (post-GA) |
Per-Saraswati-persona fine-tunes for voice + style consistency. |
Trained on licensed datasets only; per-contributor royalty waterfall. |
Failover policy: Saraswati performances must not go silent. Real-time generation
provider failure falls back to pre-rendered catalog tracks. Concert sync drift
target ≤ 25 ms maintained across providers.
Routing through V1 Isis: @oshun/isis-music registers a workflow with V1 Isis
(v1deps§9). UE's MetaSound layer consumes the resulting streams via the
world-server-issued sync timestamps.
