Public month-end proxies loaded read-only from data/market.sqlite. Sibling announcement issue 1536 remains a separate inventory row.
Disclosed rule, native span, and publication lag
Documented structure covers OPT-CMHI, OPT-1..5, STM-PRO, and OPT-D with macro vs bull-market classes and standardized March 2009 performance tables. Native observation span is unavailable on-row (text cites March 2009; longer for macro). Publication lag unknown; causal default is lag>=1.
Approach and variants
Seven candidate families with public proxies (SPY, IEF, UNRATE, INDPRO, T10Y3MM, ^VIX, and related) plus lagged workbook positions including STM-PRO. Twenty-six labeled variants executed; see research/findings/1549.md and research/findings/campaigns/1549_trial_ledger.json.
Disposition
exploratory_tested_proxy — Other/Research publication only; NO-GO for native OPTIMUM/STM/OPT-D parity; not promoted to playable Indicators.
