Three tasks for the single-iteration cycle: - Task 1 (RED): add CompileError::DuplicateParamPath + the three new tests (non-fan-in duplicate, asymmetric nested collision, by-name #59 regression), verified failing against current code. - Task 2 (GREEN): add check_param_namespace_injective, wire it into compile_with_params + both binders (before resolve), remove the fan-in machinery (signature_of/leaf_has_param/the two check fns) + IndistinguishableFanIn + AmbiguousKnob (both resolver arms -> unreachable!) + the lib.rs re-export, migrate tests 1/2, remove tests 7/8 + macd fixture. One cargo build --workspace gate over the whole enum-coupled change. - Task 3: amend the C9/C12/C19/C23 ledger notes. refs #59
