• docs/project/{architecture, epics, bugs, audit, metrics, status}/ — the ex specs/ tree; status/ holds runtime state (state.yaml, execution-status.yaml)
• Wave 1 stays OUTSIDE docs/ at repo root + .github/ — GitHub's own rendering surface, not this build
T7 — folder collision list (26 candidates → 4 real collisions)
• 6 are sub-templates already nested in a parent (api-reference/api-getting-started/sdk-overview→reference/; installation-guide→how-to/; quickstart→tutorial/; terminology-system→glossary/) — no decision needed
• 8 are Wave-1 root files, not docs/ content (bug-report, code-of-conduct+3 records, contributing-guide, our-team, contact-support)
• 4 genuine collisions, working one-by-one in priority order: README (active — T8), changelog vs release-notes, glossary vs GLOSSARY.yaml, troubleshooting vs bug RCA
