# Field notes & implementation guides Practical guides, implementation references and research from the DamageBDD stack. Start with a use case, then inspect the source and its validation scope. Canonical HTML: Start with the [platform map](../platform.md), [vision](../vision.md) or [solutions by outcome](../solutions/index.md). Read the [stack adoption guide](stack_adoption.md) for a practical first evaluation. For implementation and validation status, use the [component map](features_current.md). Search above to find a page by title, summary or document path. For an executable starting point, read the [Python quickstart for humans, bots and LLM agents](../python-quickstart.md): keypairs, authentication, Lightning or Coinstore funding, and test reports. ## Choose a customer problem Explore [Start With the Problem. Keep the Evidence.](solutions_evidence_first.md) for new evaluation guides on software acceptance, private knowledge, release identity, Nostr infrastructure, Lightning-funded jobs and a local operations workbench. Each guide identifies a first demonstration and its evidence limits. ## Browse the curated reading guide ### New: LLM evaluation for real business requirements **Developer preview — 18 October 2026.** Turn reviewed datasets and business requirements into repeatable model evaluations. Inspect failures, compare reference-assisted and unassisted runs, and make acceptance an executable DamageBDD release gate. The article covers the dashboard, node and account controls, human review, paper replay and the limits of unsigned receipts.
