memory-md-200-line-hard-truncation-cliff

MEMORY.md has a hard 200-line truncation limit enforced by the Claude Code context system. At 190 lines, the Topic Files section (bottom of file) was within 15 lines of being silently cut off every session. Critical architectural constraint: MEMORY.md must stay well under 200 lines or bottom sections (including all topic file pointers) silently vanish with no error.
