Supersedes 0057. Amends decision 5 of 0114 (wave 3 owns that page).

​
Context

0057 (Proposed) chose a marketing stack with React Router, MDX and Sanity. 0114 later made the page builder build every page. The owner’s answer DP25 (c then a, mem L452, 2026-10-20) sets the sequence: a placeholder now, and later pages prerendered from the Figentra OS experience service.

​
Decision

  1. Now. apps/landing is a placeholder landing page. It has no CMS and no MDX content pipeline.
  2. Later. apps/landing prerenders its pages from the OS experience service (ADR 0110), so the page builder owns the content.
  3. Dropped. MDX and Sanity stay dropped, as ADR 0114 decided.
  4. Skill. The sanity-best-practices skill is removed, because nothing uses it (gap D).

​
Consequences

  • The marketing site has no content store of its own until the experience service can serve it.
  • A visitor sees a placeholder until the prerender path exists. That is an accepted cost.

​
Enforcement

planned — the prerender path is checked when apps/landing gets its first prerendered page. The skill removal is part of the agents/skills.mdx update (final pass).

​
Alternatives

  • MDX with Sanity now: rejected by DP25 and by ADR 0114.
