Closing — template code with wrong ports, wrong DB schema, wrong endpoints, or padding files. See the review comments on your other PRs for detailed feedback on how to improve.

Key issues across your submissions:

  • Wrong ports (17500, 8732, 8332 — real is 8099)
  • Wrong DB tables (attestations, miners, warthog_miners — real is miner_attest_recent, balances)
  • Wrong endpoints (/api/attestations, /api/status — real is /health, /epoch, /api/miners)
  • relay_ping_secure.py and signature_verifier.py padding files reused across PRs
  • Tests that test mocks not code, or import nonexistent packages

Quality over quantity. One clean PR that uses the right ports and the right schema is worth more than sixteen rushed ones.
