`cargo install --git https://github.com/brevis-network/pico pico-cli` fails on v2.1.0: error: package `.../examples/aot_common/Cargo.toml` is a member of the wrong workspace expected: .../Cargo.toml actual: .../examples/Cargo.toml `perf` is a member of the root workspace, but it path-depended on `examples/aot_common`, which is a declared member of the nested `examples` workspace. A git source enumerates the whole repository to find the requested package, so it loads both workspaces and rejects the conflicting membership. v2.0.0 installs fine; the dependency came in with #106. `perf` only ever used one symbol from that crate -- `register_with_vm()`. So it now carries its own `src/aot_glue.rs` and depends on the generated `pico-aot-dispatch` directly, which is nobody's declared workspace member and therefore fine to path-depend on. This is the pattern already used elsewhere: `cargo pico new` ships the same file as `prover/src/aot_glue.rs`, and the AOT examples keep their own copy. The glue has to name the *generated* dispatch crate, and that crate is regenerated per guest ELF, so a shared library crate cannot hold it -- `aot-runtime` would form a dependency cycle, since `aot-generated` already depends on it. `examples/aot_common` is left untouched and stays example-only, which is what it was for. No root-workspace crate depends on it any more, so the workspace conflict is gone without touching any AOT execution path: the example binaries still call `run_aot` as a compile-time symbol and need no registration. Also drop references to internal branch and repository names from comments (vm/src/emulator/aot.rs, vm/src/proverchain/riscv.rs, aot-runtime/src/emulator/memory.rs, aot-codegen/src/compiler.rs) and point sdk/sdk's AOT note at the generated project's aot_glue.rs. Verified: `cargo install --git file://<repo> --branch <this>` now passes package selection (the only path that reproduces the bug -- cargo metadata and CI are green even on the broken tree); fmt, `cargo metadata --all-features`, the examples workspace, the CI clippy gate, `cargo check -p pico-perf --features aot` and the fibonacci AOT example all clean.
