Part of #69

Closing as stale. Phase 6 is recorded complete in ROADMAP.md and its work merged in PR #92 (v1.1.0a2): fabricated APIs purged from the documentation, deprecated legacy chapters removed, troubleshooting guide corrected, and the Sphinx build passing.

Left open when the phase landed. Note that the same fabricated-API defect class was later found in module code and tests, not just docs — see #103.
