Backend Libraries

LeafEnterprise backend libraries are ordinary Python modules, but they are documented here as formal implementation libraries because they define owned business logic and operational contracts.

Core Libraries

Library	Purpose
Savings/audit determinism	Builds governed report context, optimization context, and workbook artifacts.
Contract guarantees	Resolves exact contract/pricing/rebate evidence and blocks weak conclusions.
Salesforce ITR evidence	Mirrors request data, materializes files, and emits search-ready evidence documents.
Agent runtime	Manages task policy, traces, artifacts, SDK execution, and Service Bus dispatch.
Domo takeover	Imports Domo evidence for reconciliation without making Domo a runtime authority.

Implementation Standard

Each library should expose:

• deterministic inputs and outputs,
• explicit evidence gaps,
• backend-only source access,
• testable failure states,
• narrow browser-safe API payloads,
• runbook commands for operators.
