Rates Engine v0.5.0-rc.107

[v0.5.0-rc.107] — 2026-06-01

Tested against Stellar Protocol 23 (Whisk).

Pre-deploy operator note: aggregator restart picks up new oracle gap-detector targets. Coverage_pct values populate after the first 30-min cycle.

Fixed

• Oracle sources (band, redstone, reflector-dex/cex/fx) now have
  gap-detector targets sliced from the unified oracle_updates
  hypertable. Pre-rc.107 these sources showed n/a on the
  backfill_coverage listing because no per-source target existed.
  Same shape as the rc.104 Soroban-DEX trade targets: shared
  hypertable + per-source WhereFilter. Result: customer-facing
  coverage_pct now populates for ALL Soroban sources with a
  per-source hypertable. defindex + soroswap-router remain n/a
  because they're log-only sinks (no per-ledger hypertable rows
  to scan).
