InDesign CS6 EPUB Specialist Needed to Fix Broken Navigation TOC (Small, Technical Job)

Project: Fix EPUB Navigation TOC (InDesign CS6) I have a completed book layout in InDesign CS6 that exports to EPUB correctly except for one issue: the Navigation Table of Contents (NCX/nav.xhtml) is not generating properly. This is a small, technical job for someone who understands the CS6 EPUB export engine, including: • TOC Style mapping • Export Tagging for headings • NCX generation • nav.xhtml structure • OPF spine order • Split Document behaviour • Style based navigation The print layout is complete and stable. I am not rebuilding the book — I only need the EPUB TOC fixed so the navigation works correctly across readers. Your task: • Inspect the InDesign CS6 file • Identify the cause of the broken TOC • Repair the TOC Style / Export Tagging / NCX mapping • Export a clean, valid EPUB with a working navigation TOC • No manual EPUB “polishing” — the fix must be done at the source Deliverables: • A working EPUB with correct navigation • Notes on what was fixed (brief) • No changes to the print layout Requirements: • Proven experience with InDesign CS6 (not just CC) • Deep understanding of EPUB 2/3 export from CS6 • Ability to diagnose internal TOC/NCX issues • Ability to work directly in the InDesign file Budget: Fixed price — £175 (flexible for the right expert) This is a small job for someone who knows CS6 well. If you understand the old EPUB export engine, this will be straightforward. Screening question (required): How does InDesign CS6 handle Export Tagging for headings during EPUB export, and how does that affect the Navigation TOC (NCX/nav.xhtml)?
