Rates Engine v0.5.0-rc.35

[v0.5.0-rc.35] — 2026-05-08

Added

• /convert/[from]/[to] static-prerendered conversion pages.
  Full N×N matrix (~12k pages: 110 × 109 minus identity pairs).
  Each page renders the live mid-market rate, an interactive
  ConvertPair widget pre-filled with the pair, and "X = Y"
  snippets at common amounts (1 / 10 / 100 / 1000 / 10000) for
  SEO body content. Inverse pair, both currencies' overview pages,
  and source attribution all linked. Each page has its own
  canonical URL + OG card with the live rate baked into the title
  and description. Includes a server-side initial rate so the
  first paint is correct without a client roundtrip; the
  ConvertPair refreshes every 60s after that.

Changed

• GH Actions cost: drop arm64 from release.yml + narrow
  release-validate path filter. Every release.yml run was
  cross-compiling 6 binaries × 2 archs and pushing 6 multi-arch
  container images; arm64 had no consumers (every region is amd64)
  so it was dead-weight compute. release-validate.yml's cmd/**
  path filter was firing on every config-wiring PR (~60 runs/day);
  narrowed to only files release.yml actually consumes (workflows,
  Dockerfiles, Makefile, go.mod/sum, cut-release.sh) — the "did
  the binary cross-compile?" question is already answered by
  ci.yml's go build ./.... Re-add arm64 when an arm64 host is
  provisioned.

Added

• Configurable per-venue poll_interval for external connectors.
  ExternalVenueConfig gains a poll_interval field (Duration, empty
  defaults to the connector's built-in cadence). Bake
  [external.coingecko] poll_interval = "120s" into the archival-
  node Ansible template to silence the minute-cadence "http 429:
  Throttled" loop seen in indexer logs against CoinGecko's free tier.

• /aggregators page now lists mainnet contract addresses for
  Soroswap (router + pair factory) and DeFindex (factory + USDC /
  EURC / XLM autocompound vaults). Each row deep-links to
  stellar.expert. Sourced from each project's authoritative
  public/mainnet.contracts.json in their public repo,
  verified 2026-05-08.
