Boundary of this page
This daily read is market diligence, not investment advice, not a claim of absolute truth, and not proof that any trader should buy or sell. It answers whether this market price had enough substrate to cite, monitor, discount, or ignore at the as-of timestamp, with receipts attached in the diligence packet.
Executability scored as worse-of(spread, depth) from a single orderbook snapshot; the two were merged from the former liquidity + depth pillars to stop double-counting one correlated source.
Resolution source and rule text are present but not independently reviewed.
5/10 accounts identifiable; identity coverage 55%; top-account flow share 47%; net directional flow net sell 51%. Descriptive participant flow only; not a skill or smart-money signal.
One or more screen indicators flagged at a low level. A reason to look, not a finding about anyone.
3 linked artifacts; 0 missing hashes; 0 stale/failing sources.
How it adds up: composite = Σ(score × weight) / Σ(weight) across measured + heuristic pillars only. Pending and data-rights-blocked pillars are excluded from both numerator and denominator. Total contributing weight = 60.0.
Caveat: 1 pillar not assessed yet; the score will recompute as the substrate fills in.
