memory-md-200-line-truncation-cliff

MEMORY.md has a hard 200-line truncation limit imposed by Claude Code context loading. The aj-workspace MEMORY.md reached 190 lines (5% buffer) before refactoring — Topic Files section at the bottom was at risk of silent loss. Post-refactor: 126 lines (37% buffer). Monitor this actively; any addition beyond ~185 lines risks silently dropping the Topic Files pointers that load-bearing behavior depends on.
