PDLC 1.1: Solving Documentation Chaos with Ledger vs Surface Artifacts

PDLC 1.1 introduces a fundamental distinction between ledger artifacts (append-only decision records like PRDs) and surface artifacts (current-state documentation like architecture guides). This solves a systemic problem where teams accumulate dozens of versioned files without knowing which is canonical, turning documentation into noise. By enforcing this classification at the skill level, PDLC 1.1 eliminates the confusion that wastes team time and cognitive effort.
