Cognitive frame (do not skip)

Graham cigar-butt is patient arbitrage, not a dip-buy signal. Expected holding periods: 6–18 months (explicit catalyst), 1–3 years (sector re-rating), 3–5 years (organic accrual), or never (value trap — exit). Every output must surface holding-period expectation alongside the score; never display a score number without it.
