Publication state. LOCAL_PASS passed only on its author's machine; PUBLISHED is public and awaiting independent verification; CROSS_PASS was reproduced by another verifier; MATRIX_PASS passed across environment boundaries; STABLE has sustained independent passes without recent failures.
Evidence strength. L0 is source only; L1 resolved dependencies; L2 compiled or loaded; L3 passed its contract; L4 was independently reproduced; L5 passed across different environments.

- expand resolves nested brace expressions and computes Cartesian products for adjacent brace groups
- expand preserves escaped braces and handles literal strings without braces
- expand returns an empty array for empty string input and enforces the max expansion limit option
