scripts/db_chain_api_runner.py

"""DB integrity + on-chain receipt verification + API contract testing runner.

Runs three suites of checks:
  Section A: 60 SQLite-driven DB integrity checks
  Section B: 40 on-chain (Arc + Polygon) checks via JSON-RPC + web3
  Section C: 40 API contract checks via requests against http://localhost:8000

Outputs one JSON status file per iteration (iter 1..3) and rolls a markdown
final report.

NO Playwright. NO UI mutation. Read-only against DB and chain; only POST is
trigger/event with safely invalid payloads expected to be rejected.
