PRD File
A Plan-Review-Deliver document that stores all project state for Ralph Execute, enabling multi-session execution that survives context loss.
The PRD file is the persistent state container for complex work. It contains the project goal, phased plan with success criteria, current phase indicator, iteration count, running learnings, and blockers. Ralph Execute reads the PRD at the start of each iteration, executes one action, and writes updated state back. The file format is markdown with structured sections that are machine-parseable. After 42 PRDs and 300+ iterations, zero state has been lost to context compaction or session breaks. PRD files live in 07_execute_short_term/plans/ with an _active.md suffix while in progress.
