Potential fix for https://github.com/AetherMesh-AI/aethermesh-core/security/code-scanning/4
The best fix is to make the secret-assignment separator whitespace possessive so the regex engine cannot repeatedly repartition user-controlled whitespace while searching for a value.
Concretely, in
src/aethermesh_core/local_audit_event.py, the two\s*quantifiers surrounding the:or=separator in_SECRET_IN_TEXTare changed to Python 3.11+ possessive quantifiers. This preserves redaction of quoted and unquoted secret values while eliminating the backtracking path reported by CodeQL.A regression test locks the separator quantifiers to the non-backtracking form. No API, audit schema, or persisted file-format changes are required.
