EPUB Book Pipeline

Provides the EPUB-specific mechanical operations for extracting, chunking, rebuilding, and validating EPUB files. It handles the structural EPUB work so you can focus on whatever content transformation you need to apply in between.

Pipeline Overview

origin.epub → [Step 1: Extract] → source.md + toc_original.yaml + terminology_candidates.md
              → [Step 2: Chunk] → chunk-*.md files (for parallel processing)
              → [** your content modifications here **]
              → [Step 3: Rebuild] → modified.epub
              → [Step 4: Validate]

Execution Rule

Run the requested pipeline step directly without pre-checking dependencies, environment variables, or configuration. If something is wrong, the scripts will fail with clear errors — check and fix only then.
