> Purpose. The public face of the SciDEX economy. A visitor lands on /showcase and sees, for each artifact class, 2+ high-value showcase artifacts with their full provenance chain visible on demand. A separate /showcase/economy dashboard shows the overall system state — gap coverage, composite-value distributions, weight-vector artifacts, the frontier of open cells.
>
> Ties together the existing 959aa430_artifact_gallery_spec.md (29K+ artifacts gallery, browsable) and the showcase audit in 8c1ca59e-a8d6-49a3-8b20-f3b2893bf265_showcase_presentation_quality_spec.md. The gallery is "all artifacts", showcase is "the best N per class with full provenance".

7. COMPOSITE
V = 0.78 (weights: [0.2, 0.15, 0.2, 0.2, 0.1, 0.15] — current weight-vector artifact: wvec-v3)
8. SIZE / MARKET CAP
Size S = 45 deployments (p50; range p10=12 … p90=180)
MarketCap = V × S = 35.1 deployments-expected
OpenInterest = 2,400 tokens across 34 positions
Volume_24h = 180 tokens (medium activity)

Showcase since: 2026-05-12 (stable for 4 weekly meta-arena runs)Each section is collapsible. The transcript sub-view is the most important element — it's the readable argument for why this artifact is in the showcase.
/showcase/modelSeparate tab listing artifacts flagged as model artifacts across all classes. Each entry also shows its role in the economy (e.g. "current composite-value weight vector" or "best-of-class invention for CRISPR safety" or "highest-IIG experiment design pattern"). Model artifacts are a small, curated set — typically under 20 at any time.
/showcase/economyOne-page overview:
(domain, cell) colored by saturation; dot SIZE scales with the cell's artifact market-cap sum; dot COLOR is V. Open cells (no artifact) render as hollow dots sized by gap-S estimate. Clicking a cell opens its artifact list.V × S, log-scale on the x-axis so grandiose low-confidence artifacts appear next to tight high-confidence ones.V, y = S (log), each artifact a dot. The top-right quadrant is the "high probability + high impact" corner — that's where showcase artifacts live. Moonshots are top-left (high S, low V); trivially-true-but-small are bottom-right.market_cap, not raw counts, so a handful of high-impact artifacts dominate the visual (correctly).Volume_24h and total OpenInterest.
