Milestone D.6.3 — Cross-site nav + sitemaps

Status: Complete (unified-domain landing migration)
Goal: D.6
Phase: 1.5 — Docs Site
Wave: 12
Estimated effort: 1 hour
ADR required: None

Spec detail: MASTER_BRIEF.md Part D (D.6.3).

Why This Milestone Exists

Product marketing and documentation now ship from a single Next.js static export at https://ibexharness.com (landing at /, docs at /docs, blog, benchmarks, releases, roadmap). The legacy host docs.ibexharness.com becomes a 301 redirect to the same paths on apex after DNS cutover.

robots.ts and sitemap.ts emit apex URLs only. Internal nav links Home → / and Docs → /docs/... — no external cross-domain hops.

Final launch milestone before Phase 2.1.1 unblocks.

---

Non-Goals

• Separate ibexdepo TanStack landing deploy (retired after cutover)
• Shared auth between marketing and docs (unchanged)
• Blog or changelog duplicated on a second domain
