Case boundary

A publishing production system that builds web, EPUB, PDF, and M4B editions, enforces release readiness, sells private digital downloads, and routes paperback orders to print fulfillment.

Claim boundary

Only books that pass final publication and commercial readiness gates are represented as for sale.

Raintree Press treats books as versioned software artifacts, with source manuscripts, build products, proofs, commerce, delivery, and fulfillment in one controlled workflow.

System

  • Git-backed Markdown chapters and book metadata build into public web editions, EPUB, PDF, samples, and frozen release directories.
  • Authenticated libraries, one-time Stripe Checkout, entitlements, and private Cloudflare R2 downloads handle direct digital sales.
  • Paperback webhooks create fulfillment records and submit eligible paid orders to Lulu.
  • The audiobook pipeline supports local Kokoro, OpenAI, and ElevenLabs generation with shared speech preparation and ffmpeg mastering.

Control

  • A finish-first policy requires final publication status, sale status, ISBN metadata, content audit, and export validation before checkout is enabled.
  • Paid audio generation supports estimate-only mode, cost and character caps, chunk caching, source hashes, QA results, and output manifests.
  • Print production remains in sandbox until files, package configuration, and webhook behavior are verified.

Proof

  • Every audiobook output can carry provider settings, source hashes, chunk hashes, cache hits, QA results, and preview metadata.
  • Writing audits, claim triage, export validation, release freezing, and app checks are executable commands.
  • Direct ebook delivery and print fulfillment share durable purchase and entitlement records rather than ad hoc file links.
