Market Trust diligence packet
Starmer out by June 30, 2026?
One-screen answer to a buyer's question: can this market price be cited, used with caveats, discounted, or ignored? The packet separates the verdict from evidence confidence, source freshness, participant quality, integrity screens, and receipts.
So what?
Monitor, but do not cite as current. The evidence is useful as an archived read until the data freshness window refreshes.
Freshness gate: Diligence packet is stale for current product claims. Treat this as archived evidence and wait for a refresh before demos or outreach.
Memo language
Convexly rates this polymarket market "Starmer out by June 30, 2026?" as Do not cite. Use only as a review target. Current-card issues must clear before this price is used as evidence. Caveat to carry: Resolution-rule text is missing, so the card cannot receive a clean citation verdict. This is market diligence, not a trading instruction or proof that the market probability is correct.

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 = 80.0.
Caveat: 1 pillar pending — the score will recompute as the substrate fills in.

Boundary of the packet
This packet 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 the market price has enough substrate to cite, monitor, discount, or ignore with receipts attached.
