Rates Engine v0.5.0-rc.47

[v0.5.0-rc.47] — 2026-05-11

Added

• /v1/assets is now a strict superset of /v1/coins. The
  listing endpoint sources from ListCoinsExt when a CoinsReader
  is wired, projecting each row into AssetDetail with the full
  coin-overlay shape (price_usd, volume_24h_usd,
  market_cap_usd, circulating_supply, change_*_pct,
  issuer_scam_reason). Pagination uses the same
  <observation_count>:<asset_id> cursor format as /v1/coins.
• /v1/assets?issuer=<G-strkey> filters the listing to one
  issuer. Wires straight through to ListCoinsExt's Issuer option.
  Unblocks /v1/issuers/{g} → /v1/assets migration in the
  explorer.
• AssetDetail adds slug, first_seen_ledger,
  last_seen_ledger, observation_count — the catalogue
  identity + activity-metadata scalars CoinRow carries but the
  rc.46 overlay didn't lift. Lets explorer consumers drop their
  parallel /v1/coins/{slug} fetches.

Changed (explorer)

• Every explorer /v1/coins fetch site migrated to /v1/assets.
  useCoins hook keeps its name + return shape for ergonomic
  continuity but the underlying API call is now /v1/assets,
  envelope-reshaped from {data:[], pagination:{next}} into the
  legacy {coins:[], next_cursor, limit} so the 4 home consumers
  (HomeTopMovers, HomeTopAssets, HomeNetworkStrip, AssetsTable)
  work unchanged. Direct fetch sites (asset-detail listing cache,
  sitemap, embed-asset, issuer page) hit /v1/assets end-to-end.
