The board grows from 6 pre-IPO assets to 81 assets / 167 mints in two sections: pre-IPO (spread-only, no reference price exists) and tokenized stocks measured against the real exchange price of the underlying. - data/equity-seed.json: every multi-issuer public equity in the tokens.xyz registry, with hand-curated underlying tickers (74) and split scales (Netflix tokens are pre-split shares -> anchorScale 10), regenerated by data/extract-equity-seed.ts and live-verified by scripts/verify-seed.ts (all 33 assets with DEX prices agree within ±4%; sk-hynix is KRW-listed, spread-only) - underlying_ticks (migration v2): anchor exchange price per ticker per stock cycle via the Yahoo v8 chart API, polled every 5 min, kept forever - two-tier DexScreener polling: pre-IPO mints every cycle, public mints every 5th cycle (~167 req peak minute, under the ~300/min limit) - premium = token price / (anchor x scale) - 1, computed at read time from the two stored series, surfaced per variant on the board and /api/latest - /healthz now watches both legs: collectorDegraded (DEX poll stalled) OR anchorsDegraded (no underlying tick in 3 stock cycles, e.g. Yahoo blocking); pre-IPO-only deployments skip the anchor leg Verified live end to end: boot -> both legs degraded -> anchors green -> full recovery; 40 variants showing live premiums (BAC xStock -14.4% on a thin $1k pool, UNH +4.1%, NFLX -0.39% via x10 anchor).
