VIP-36: the declaration manifest (vibelang.manifest.json) (open)

Status: open, 2026-10-29. Not part of the first release. Will: "Yup open vip for that".

What it was

A file listing which exports were compiled from .vibe, so other VibeLang code could "trust" them: a trusted export's failures were known, and any other TypeScript call was suspected of throwing (D500, D516, D530, D556).

Why it is not needed now

VIP-27 writes @throws on every exported function, @throws {never} included, and VIP-4 says a function without @throws throws unknown. What an import may throw now travels in its declaration file, the same for VibeLang and hand-written TypeScript.

History

The loop: Astra raised it three rounds running (round 9 M2, round 10 M3, round 11 M3). Each round blocked one way to replace a certified export, and the next round found another (a write through a mutable alias, for example).
