- Q3: ThinkPHP View layer security audit complete
  - parseVar regex breaks on hyphen: \$vr-场馆 → \$vr only
  - Default htmlentities filter protects XSS
  - \$vr- prefix spec names are LOW risk in all rendering paths
- Q4: Recommend Plan A (one SKU per seat) for security
  - Native DB-level atomic inventory = lowest oversell risk
  - Full ShopXO spec mechanism alignment
  - Clear ticket traceability per SKU
