Define the canonical prepare-execution model for single-step and multi-step product flows. Implement this as a focused 0.5-day slice in the execution-layer codebase under the Execution Planning lane and Execution Capability feature, keeping the change scoped to the smallest backend or adapter surface needed to complete 'Document execution planning contract'. Define or update the contract, schema, or interface first so downstream integrations consume a stable capability surface. Capture the implementation decision in the relevant docs artifact so the backlog item leaves behind reusable project guidance. Validate any execution semantics, chain constraints, or adapter registration assumptions touched by the change. Acceptance notes: the item should be independently shippable, match the capability-first architecture, and leave the board with a clear implemented outcome that can be surfaced through GitHub Project notes.
