Rates Engine v0.5.0-rc.76

[v0.5.0-rc.76] — 2026-05-24

Fixed

• **internal/config/validate.go KnownSources was missing cctp
  • rozo (#40 / #41).** The two new sources were wired into
    cmd/ratesengine-indexer/main.go::buildSources and their
    hypertables migrated, but the boot-time Validate allow-list
    wasn't updated — so any operator who set
    ingestion.enabled_sources = […, "cctp", "rozo"] got
    ingestion.enabled_sources has unknown source "cctp" and a
    systemd restart-loop. Caught on r1 mid-/loop while doing the
    rc.75 follow-up rollout: indexer restart-counter hit 5 in 50 s
    before TOML was reverted. The KnownSources comment block
    ("DO NOT import source packages from config…") already calls
    out the manual mirroring step; this is just landing the missed
    entries.

Added

• verify-archive tip-pinning resume across SIGTERM (#62).
  Sister fix to per-chunk resume from rc.75. The per-chunk Done
  flags were already persisted as chunks completed, but the
  systemd unit omits -to and resolves it to the live bucket tip
  at launch — so a SIGTERMed bootstrap relaunched 30 min later
  had a new tip, resumeChunks failed plan-match, and every Done
  chunk got re-walked. Now, before live-tip resolution, the
  walker checks for a prior in-progress run on this tier; if
  From + Workers match and To > 0, it adopts that pinned tip and
  skips the live FindLatestLedgerSequence call. The
  resumeChunks plan match then succeeds and only the unfinished
  chunks run. The new ledgers in [old_tip, new_tip] are picked
  up by the next nightly fire's -from-last-verified increment.
  Helper: pinnedTipFromPriorRun in
  cmd/ratesengine-ops/verify_archive_state.go. 4 unit tests
  covering happy path, no-prior, From/Workers mismatch, and the
  defensive To=0 case.
