05 Tomorrow's tripwires

Bear Market runs a median of 2 session(s) (max 18) — this is session 18. 18% of exits went up.
Market Health crosses the 50 midline
Market Health Index (MHI) at 7.7 — a close back above 50 would end the 1st-percentile read.
Phase slips to Bear Market
0.0% of Bear Market exits went straight to Bear — the conditions analog's worst 5-session outcome (−4.86%) lives on that path.
