Summary
Security invariant
Subdirectory hint discovery may only read hint files from canonical descendant directories of the session working directory.
Addresses project-loupe/audit-goose#54.
Validation
cargo fmt --allcargo test -p goose hints::load_hints::tests::(25 passed)cargo build -p goosecargo clippy -p goose --all-targets -- -D warningsThe regression coverage exercises traversal outside the boundary, an outbound directory symlink, an in-boundary symlink alias with canonical deduplication, and retry after a missing parent is created. Symlink-specific tests are Unix-only; the containment implementation uses
std::fs::canonicalizeon every platform.This finding was discovered by Project Loupe.
