Objective
Independently replicate the distinct RecessionAlert inventory row for McClellan Liquidity Indices from the checked-in offline snapshot without live-site requests, credentials, private account data, or canonical crawl-database mutation.

Asset SHA256 provenance: linked_assets=0. Public proxies loaded read-only from data/market.sqlite.
Disclosed rule, native span, and publication lag
Documented construction covers net ADV−DECL volume, 19/39 McClellan EMAs, VMCOS, VMCSI, EMA(10)/EMA(21), STL zero-cross buy/sell, and an escalating alert ladder. Native observation span is unavailable on-row (article-only snapshot). Publication lag unknown; causal default is lag>=1.
Approach and variants
Five candidate families with public proxies (SPY, QQQ, IWM, ^GSPC, ^VIX, WALCL, BAA10Y, IEF). Eighteen labeled variants executed; see research/findings/1472.md and research/findings/campaigns/1472_trial_ledger.json.
Disposition
exploratory_tested_proxy — Other/Research publication only; NO-GO for native McClellan Liquidity Indices parity; not promoted to playable Indicators.
