Rates Engine v0.5.0-rc.28

[v0.5.0-rc.28] — 2026-05-07

Added

• Curated known-issuer metadata fallback on /v1/issuers and
  /v1/issuers/{g_strkey}. Top issuers (Circle/USDC, Aquarius/AQUA,
  Ultra Capital/yXLM, Stronghold/SHX, MoneyGram, AnchorUSD) now
  render with home_domain + org_name populated. Until the
  account-observer-to-issuers upsert path lands (see investigation
  task), the production issuers.home_domain column stays empty
  for every issuer; the fallback fills the gap at the wire boundary
  for the most-asked-about anchors. DB-populated values still take
  precedence.

Changed

• AssetLabel extracted to shared component at
  web/explorer/src/components/AssetLabel.tsx. Was previously
  copy-pasted into 5 view files (markets, dexes, dexes-by-source,
  exchanges, oracles) — diverged subtly across copies (numeric
  XLM, missing crypto: handler, missing SAC). Now everywhere
  resolves SAC contracts via /v1/sac-wrappers consistently and
  any future canonical-form addition (lp:…) needs one edit not
  five.
• Currency converter dropdown is now a searchable combobox
  on /currencies/[ticker]. The plain <select> over 100+
  currencies was unusable; the new picker filters by typed
  prefix, navigates with arrow keys, and selects with Enter.
  Pure React, no extra dependencies.

Fixed

• /research/architecture, /research/discovery,
  /research/operations 404 — only [slug] subroutes existed;
  the category index 404'd. Add a small index page at each that
  lists the curated docs for that category, with a back link to
  /research.
