feat(noir-projects): publish compiled protocol artifacts to npm - #25075
Merged
Conversation
Publishes the compiled Noir protocol circuits, mock circuits and protocol contracts as three npm packages, so a repo without a Noir toolchain can generate its own TypeScript bindings from them. Staging copies each subproject's build output into the package that publishes it, strips the source mapping from the protocol circuits to match what noir-protocol-circuits-types publishes today, and checks every staged file against the tarball npm would upload before anything is published.

Motivation
The compiled Noir artifacts under
noir-projects/fndare only reachable from inside this repo. A separate repo generating TypeScript bindings from them has no Noir toolchain and no way to compile them itself, so it needs them from npm.The change
Three new packages, published from
noir-projects/fndon a release tag:@aztec/noir-protocol-circuits-artifacts— the protocol circuits, plus the reset config and dimensions files that the reset-data and ABI generators read@aztec/mock-protocol-circuits-artifacts— the mock circuits used by proving system integration tests@aztec/protocol-contracts-artifacts— the contracts named inprotocol_contracts.json, plus that manifestThey carry raw artifacts only. Generating TypeScript from them stays with the consumer.
Each package is assembled at release time into a
dist/staging directory, rebuilt from nothing on every run and gitignored, following whatnoir/bootstrap.shand bb.ts already do for their generated packages. The manifests declare nofileslist anddistcarries no ignore file, so npm packs the directory wholesale and the staging code is the only place that decides what ships.The protocol circuits package blanks
file_mapanddebug_symbols, a fifth of its download that nothing generating bindings reads. The contract artifacts keep theirs because PXE resolves a failing public call against contract debug info.Nothing consumes the packages yet: the in-repo generators still read the target directories directly, and
noir-projects/fndis not in theprivate_releaselist.
