Add modules/twap-monitor/ as a workspace member. Cargo.toml declares [lib] crate-type = ["cdylib"] for WASM Component output, and pulls the deps the TWAP module path needs: cowprotocol (default-features off — only typed primitives and OrderCreation surface needed), alloy-sol-types (event/return decoding lands in BLEU-826/827), and wit-bindgen. src/lib.rs binds against the shepherd:cow/shepherd world (event- module imports + cow-api). generate_all is required because the world include pulls nexum:host/types across packages — without it, wit-bindgen panics on the missing cross-package mapping. init and on_event are stubbed: init logs once; on_event is a no-op until the Event::Log / Event::Block dispatch lands in BLEU-826 / BLEU-827. Verification: cargo build --target wasm32-wasip2 --release -p twap-monitor emits a 65 KB .wasm. Engine load is gated on module.toml (BLEU-834).

Summary
modules/twap-monitor/as a workspace member with[lib] crate-type = [\"cdylib\"]for WASM Component output.cowprotocol(default-features off),alloy-sol-types,wit-bindgen— pre-pulled so BLEU-826/827/828 can layer in event decoding and submission without churning Cargo.toml.src/lib.rsbinds againstshepherd:cow/shepherdworld;initlogs once,on_eventis a no-op stub until BLEU-826 (TWAP indexing) and BLEU-827 (poll path) land.generate_allis required because the shepherd world include pullsnexum:host/typesacross packages — without it,wit_bindgen::generate!panics on the missing cross-package mapping.Base:
dev/m2-base(carries the in-flight nullislabs/shepherd PRs #8/#9/#12/#15 so M2 can build on top of them while upstream review continues).Linear: BLEU-825.
