Rates Engine v0.5.0-rc.79

[v0.5.0-rc.79] — 2026-05-26

Fixed

• migration 0041 PK + InsertSorobanEventsBatch ON CONFLICT
  shape mismatch. rc.78's internal/storage/timescale/soroban_events.go
  ON CONFLICT clause referenced (ledger, tx_hash, op_index, event_index) — the original sub-agent design. TimescaleDB
  rejected that PK on the hypertable (TS103: unique index must
  include the partitioning column). Migration was fixed locally
  to (ledger_close_time, ledger, tx_hash, op_index, event_index)
  • same ordering on the ON CONFLICT (commit 6347b54f), but
    rc.78 binary shipped with the OLD ON CONFLICT clause. Result:
    every batch insert on r1 returned 42P10: no unique or exclusion constraint matching ON CONFLICT specification. Zero
    rows landed in soroban_events. rc.79 ships the matching ON
    CONFLICT clause so live ingest writes succeed.
