Purpose

Describe rendering JSONL puzzle packs into printable PDF output.

Requirements

Requirement: Print Adapter Registration

The PDF export pipeline MUST use built-in print adapters registered by builtinprint and reject games without paper rendering support.

Scenario: Unsupported game

• WHEN a JSONL record references a game without a print adapter
• THEN PDF export reports the unsupported puzzle instead of silently rendering invalid output

Requirement: PDF Layout

The PDF renderer SHALL support half-letter interiors, duplex-booklet sheet layout, cover/title pages, metadata, instructions, puzzle pages, answer pages, and automatic page-count padding.

Scenario: Duplex booklet

• WHEN --sheet-layout duplex-booklet is selected
• THEN PuzzleTea emits landscape letter sheets with two portrait half-letter pages per side and cover stock placement preserved

Requirement: Difficulty Rendering

PDF ordering and difficulty display MUST prefer actual Elo, then target Elo, then legacy mode fallback when Elo metadata is unavailable.

Scenario: Render difficulty

• WHEN an exported record contains actual Elo
• THEN the PDF uses that value for ordering and difficulty display
