 ## Crate Architecture
 
-All crates live in `crates/`. Key crates:
+revive compiler library crates live in `crates/` (revive Rust workspace). Tooling is not necessarily part of the workspace.
 
-- **resolc** - Compiler driver binary and library; orchestrates the full pipeline
-- **revive-yul** - Yul lexer, parser, and LLVM IR lowering; implements visitor pattern for AST traversal
-- **revive-llvm-context** - LLVM code generation logic (decoupled from parser)
-- **revive-linker** - Links RISC-V ELF to PolkaVM blob via LLD and polkavm-linker
-- **revive-runner** - Executes contracts in simulated pallet-revive runtime; provides declarative test spec format
-- **revive-integration** - Integration test cases using revive-runner
-- **revive-differential** - Differential testing utilities against EVM
-- **revive-runtime-api** - Low-level runtime API bindings to pallet-revive
-- **revive-stdlib** - Compiler standard library components
-- **revive-common** - Shared constants and utilities
-- **lld-sys** - FFI bindings to LLVM's LLD linker
