Review & budgets

We publish our review criteria in full, on purpose: if you can see the bar, you can clear it. Every submission — every version — passes the same gates, and the same checks run inside Studio while you author, so a rejection is never a surprise. Machines check safety and performance; a human decides what publishes.

The gates, in order

Extract — archive sanity and size.
Static analysis — imports may be the world SDK, three, and a fixed set of three/addons/* only. No eval, dynamic import(), network APIs, storage, timers, ambient globals, realm/prototype tricks, or absolute-URL literals; document only as createElement('canvas'). v1 worlds are fully procedural (no external assets). The full list is in agents.md.
Typecheck — against the pinned world-SDK types.
Rebuild — with SYQEL's pinned toolchain. The fleet only ever runs bytes SYQEL built.
Behavioral — your world is built headless under instrumentation; any attempted network or global access fails the gate.
Budgets — the table below.

Then human review, then publication into the signed channel. Apps verify the channel signature and each module's integrity hash before anything renders. A published world can be delisted by you, or revoked by SYQEL — revocation removes it fleet-wide.

Performance budgets

Calibrated on real TV hardware (Fire TV Stick 4K Max, Apple TV 4K).

Budget	Limit	Why
Source archive	`≤ 2 MB`	Submissions are source, never bundles — SYQEL rebuilds them.
Built bundle	`≤ 256 KB`	Weight belongs in CDN assets, not code.
Staged build	`≥ 5 slices, no slice > 40% of a real build`	TVs take frames between slices.
Draw calls (est.)	`≤ 300`	The difference between 57 fps and 25 fps on a TV.
Triangles	`≤ 600k`
Textures	`≤ 2048×2048 each, ~64 MB total`	Procedural — painted in a canvas.
Built bundle	`≤ 256 KB`	Worlds carry no external assets in v1.
