 ### Build Tasks
 
 All tasks are Nix packages run via `nix run`. From a consuming repo:
 
 #### Solidity
 
-- `nix run ..#rainix-sol-prelude` — forge install + build
 - `nix run ..#rainix-sol-test` — forge test
 - `nix run ..#rainix-sol-static` — slither + forge fmt check
 - `nix run ..#rainix-sol-legal` — REUSE/DCL-1.0 license compliance
 - `nix run ..#rainix-sol-artifacts` — deploy to testnet
 
 #### Rust
 
-- `nix run ..#rainix-rs-prelude` — environment prep (currently no-op)
 - `nix run ..#rainix-rs-test` — cargo test
 - `nix run ..#rainix-rs-static` — cargo fmt + clippy
 - `nix run ..#rainix-rs-artifacts` — cargo build --release
