Rates Engine v0.5.0-rc.27

[v0.5.0-rc.27] — 2026-05-07

Fixed

• status.ratesengine.net stuck on "Status unknown" — the
  status site fetches /v1/status cross-origin from
  status.ratesengine.net but only ratesengine.net and
  api.ratesengine.net were in the API's allowed_origins. Add
  status., docs., dashboard., and www. subdomains to the
  ansible template so future re-renders preserve the fix.
  Production /etc/ratesengine.toml was hand-patched on r1
  immediately and the API was restarted; verified
  Access-Control-Allow-Origin: https://status.ratesengine.net
  on responses.

Added

• GET /v1/sac-wrappers — read-only endpoint exposing the
  operator-config Stellar-Asset-Contract wrapper map (SAC C-strkey
  → "CODE-ISSUER" classic asset). The explorer's pool-row
  AssetLabel now resolves SAC contracts to readable symbols
  (e.g. USDC with SAC subtitle) instead of CAS3J7…OWMA.
  Soroswap / Phoenix / Aquarius / Comet emit base/quote as the
  SAC contract address in their swap events at the wire — this
  surfaces the underlying classic asset client-side.
