Lua Phase Timing and Variable Scope Cause Incorrect Routing

7/10 High

Variables set in one Lua phase may not be available or may be stale in later phases if timing and scope are misunderstood. Logic relying on variables set in different phases (e.g., `set_by_lua*` vs. `access_by_lua*`) results in NGINX variables being empty or holding stale values, causing incorrect routing, logging, or access decisions.
