Self-contained prompt for a fresh Claude Code session. The next session
reads it once, has all the context it needs, produces the WB-usage
closure audit at docs/research/2026-05-21-phase-o-t1-wb-audit.md,
and stops before any extraction. Investigation-only (the /investigate
skill applies). User reviews the audit before T2 begins.
