Signal transition events (top/bottom indicators)

Event log of discrete transitions across 13 declared signals (bullmarket stages 1-5, pulse band, hash ribbons, MVRV-Z regime, Mayer band, NUPL zone, Pi-Cycle cross, golden/death cross, price vs 200W-MA). Each event carries from/to state, occurred_at vs event_date (confirmation day — use event_date for forward evaluation), declared threshold params, the driving value (trigger: field + value at occurred_at and at event_date, lhs/rhs for A-vs-B rules), btc_close and drawdown vs the ATH up to that day. Events are reconstructions from today's stored series under declared rules, not forecasts; the per-signal coverage block names the measured reconstructable-from date. Window via days, tier-capped (Free 30d, Pro 365d, Power 3650d); the range block declares requested vs. granted.
