SEO library — canonical master index
26-discipline expansion — 2026.09.09-d26: Route engineering, SEO, AI visibility and publication work through the discipline operating library. Read the master router, cross-discipline playbooks and public expertise layer. New role IDs do not change commercial tiers, pricing or the retirement of Tier 13. Baseline legacy review boundaries remain in force.
Edition 2026.09.09 · Generated navigation, not a certification of every legacy claim.
169 active Markdown documents: 27 new researched modules, nine rewritten core guides, this regenerated index, five targeted-patch legacy guides and 127 other retained legacy documents. The 146 unique original files are preserved separately with hashes. Tier 13 stays retired; no tiers were renumbered.
Start with the build reference, evidence rules and audit report. Current researched guidance overrides conflicting legacy material. A legacy file is useful background, not an instruction to deploy its code or accept its statistics.
