Root CLAUDE.md said shared defaults live in .claude.json and
machine-local overrides in .claude/settings.local.json. Both are
wrong: .claude.json is Claude Code's own permission config, unrelated
to this project. The project's actual shared-defaults file is
.claw.json (model aliases etc.), and its local-override path is
.claw/settings.local.json — matching rust/CLAUDE.md and .claw.json.

The Rust crate layout expects formatting to run from the rust directory, so add a root-level wrapper that preserves the working command while forwarding user flags like --check. Documentation now points contributors at the wrapper instead of the misleading virtual-workspace manifest invocation.
Constraint: Root-level cargo fmt --manifest-path rust/Cargo.toml is misleading for this virtual workspace
Rejected: Document cd rust && cargo fmt directly | a root wrapper gives one stable repo-root command
Confidence: high
Scope-risk: narrow
Tested: scripts/fmt.sh --check
Tested: git diff --check
