Constraint: G002-alpha-security requires direct file-tool escapes to fail before reads while accepting the canonical runtime error text.
Rejected: weakening the test to accept successful reads | the verified behavior denies the escape and only the assertion vocabulary was stale.
Confidence: high
Scope-risk: narrow
Directive: Keep path-scope tests asserting denial semantics, not a single legacy wording.
Tested: cargo fmt --manifest-path rust/Cargo.toml --all -- --check; cargo test --manifest-path rust/Cargo.toml -p tools path_scope -- --nocapture; cargo test --manifest-path rust/Cargo.toml -p tools --test path_scope_enforcement -- --nocapture; cargo test --manifest-path rust/Cargo.toml -p runtime workspace_ -- --nocapture; cargo test --manifest-path rust/Cargo.toml -p rusty-claude-cli --test output_format_contract -- --nocapture; python3 -m pytest tests/test_security_scope.py -q; cargo check --manifest-path rust/Cargo.toml --workspace; git diff --check
Not-tested: full cargo test --workspace due known unrelated session_lifecycle_prefers_running_process_over_idle_shell failure.
