The ? -> [^/] replacement ran AFTER the {{GLOBSTAR_SLASH}} placeholder was
restored to '(?:/.+/|/)', corrupting the group opener '(?:' into '([^/]:' —
every rule pattern containing a mid-pattern '/**/' silently matched only the
zero-dir branch and live rules were flagged 'matches no files' (CA-RUL).
Found by dogfooding /config-audit implement on a throwaway repo copy: the
implementer agent's correct 'posts/**/post.md' rule was flagged dead.
Fix: run the ? replacement before placeholder restoration. Fixture outcomes
byte-identical; frozen v5.0.0 baselines untouched.
