… XDR Rust→client bridge for testnet wiring: `perch-plan <doc.json> <interpreter_wasm_hash>` compiles a PolicyDoc and prints each rule's InstallParams as ScVal XDR (hex) — the exact bytes an off-chain applier drops into a Nido account's `policies: Map<Address, Val>` against the deployed interpreter. The RPN lowering is Rust-only and needs a native Env, so this is how TS/browser tooling obtains a byte-identical program (a UI showing a policy and the chain enforcing it agree on doc_hash + program bytes by construction). Seed of the future in-browser wasm compiler (v2). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

What
Adds
perch-plan, a small Rust bin that compiles aPolicyDocand prints eachrule's
InstallParamsas ScVal XDR (hex) — the exact bytes an off-chainapplier drops into a Nido/OZ smart account's
policies: Map<Address, Val>against the deployed interpreter.
Why
The RPN lowering (
perch_compile) is Rust-only and needs a nativeEnv(a
wasm32-unknown-unknownbuild is refused by soroban-sdk's build.rs). This CLIis the Rust→client bridge for on-chain wiring: TS/browser tooling gets a
byte-identical program, so a UI showing a policy and the chain enforcing it
agree on
doc_hash+ program bytes by construction. It's also the seed of thein-browser wasm compiler (v2).
Proven on-chain
Used to install a real perch policy on Stellar testnet and prove enforcement
end-to-end (via nido's new
perch-status-onchainexample): the interpreter(

clearfor the same key — the first time perch runs against a realnetwork's auth framework.
