Detailed Description

Legacy per-component data record stored in the page-based allocator (predecessor of ComponentMemory).

In the older MemoryManagerX design each component's record (COMPONENTDATAHEADER plus parameter and private-data areas) lived in its own memory page, located via a shared ComponentMap. Superseded by ComponentMemory.h, but kept for compatibility and tests.

Note: Several struct names here (ComponentStats, PARAM_* macros) intentionally shadow newer definitions; this header must not be mixed with ComponentMemory.h in one TU.

Warning: Shared-memory layouts; changing any struct here requires a full rebuild of all binaries (make clean && make) — see MemoryManager.h for the ABI warning.
