Stellar Index v0.46.0

[v0.46.0] — 2026-08-28

Closes the coverage gap behind stellarindex_assets_popular_priceless,
plus FX resilience and a widened OHLC ladder.

Added

• Soroban-native assets are priceable through one substance-gated hop.
  The catalogue prices the long tail through exactly two hard-coded shapes
  (direct_usd, asset_vs_xlm), both built on classic_assets, which is
  structurally classic-only (issuer_g_strkey NOT NULL) — so no Soroban
  contract asset could reach either, however deep its market. CAUP7NFA…
  traded $71.8k over 6,418 trades in 7 days and served no price. Now
  price(A) = vwap(A/hop) × price(hop), with both legs independently
  substance-gated: a two-hop price inherits its weakest leg, and an
  ungated intermediate could reprice everything quoted against it. Served
  last (never overriding an observed price) and marked
  price_basis: "transitive".
• ECB standby for the fiat-FX feed. massive is a paid feed and was
  the only series in stellarindex_external_fx_last_quote_unix, so a
  lapse or a 429 broke every fiat-quoted pair once the 7-day forex-snap
  lookback expired. ECB is free, keyless and authoritative; rates are
  rebased onto USD (usdRate(X) = eurRate(X) / eurRate(USD)).
  fx_quotes.source and the metric label follow the feed that actually
  served.
• OHLC 2h / 12h / 3d / 2w. Closes the resolution gap against
  stellar.expert. No backfill — /v1/ohlc already re-buckets a finer
  continuous aggregate at query time, and all four divide cleanly into
  existing CAGGs.

Changed

• The priceless-coverage tripwire's priced CTE now recognises the same
  one-hop path the resolver serves — with the same substance floors
  ($1,000 / 20 buckets / 6h), grouped per (asset, hop). Without those
  floors the extension was a bypass, not a fix: 955 assets became
  "priced", of which USDMPOOL ($798/24h) and yHELIX ($296/24h) would have
  gone silent while remaining genuinely unpriced. Gated, it adds 7.

Fixed

• Test-net builds no longer advertise themselves as mainnet: /network
  reported "Pubnet" on testnet, 13 stellar.expert links pointed at the
  mainnet explorer, robots/sitemap/canonicals named the production
  origin, and API_BASE_URL fell back to the mainnet API when
  NEXT_PUBLIC_API_BASE_URL was unset. A CI guard now greps for these
  literals.
• Transaction links point at our own /transactions/{hash} instead of a
  third-party explorer; outbound cross-references consolidated into one
  line offering stellar.expert and stellarchain.io (network-aware; the
  latter is the only one that exists for futurenet).
• galexie-archive-fill, verify-archive-tier-b, archive-completeness
  and pgbackrest-backup are omitted on networks where they cannot work.
  Tier B was anchoring testnet ledgers against pubnet hashes, and
  archive-completeness was fetching pubnet checkpoints into a test-net
  store — both wrong-network data paths, not mere noise.
• config-assertions no longer fails on layers a host doesn't have
  (ZFS on the no-ZFS lean VMs); promtail no longer ships to a Loki that
  isn't installed.
• scripts/dev/verify.sh mirrors CI's lint-metric-refs self-test, and
  its gitleaks working-tree scan no longer red-flags real ansible vault
  files — both had made cut-release.sh unrunnable on an operator box.
