description: |
  FinOps mapping for Tensor's three commercial surfaces — REST API access, on-chain
  protocol fees (taker + maker), and AMM market-making positions. Tensor does not
  publish a SaaS-style invoice; FinOps tracking is split between Tensor (API access)
  and the Solana ledger (per-transaction fees, royalties, and pool PnL).

governance:
  reporting:
  - Reconcile API-driven volume against on-chain settlement via Helius / RPC indexers.
  - Use the WebSocket newTransaction channel as the source of truth for realtime trade attribution.
  budget-controls:
  - Cap `maxPrice` on every buildBuyTx call.
  - Pre-fund and rotate shared escrow accounts rather than holding large SOL balances per-pool.
