decision
Chose Option 3 (single file + compact summary at top) over Option 1 (search-only, no summary) and Option 2 (split into per-section files). Reason: one file to maintain, but LLMs can load just the ~50-line summary for routing and only pull full sections when needed. File is ~74KB/15-18k tokens — too heavy to load wholesale but well-structured for selective access.
