New docs/three-tier-context.md (110 lines) documents Voyage's position as
Tier 1 in a three-tier ecosystem with upstream consumers (app-creator,
app-factory; both currently in private incubation). The brief identifies
upstream-consumed contracts (brief.md format, /trekplan CLI, handover
schemas), prescribes stability principles, and explicitly preserves
Voyage's runtime agnosticism — no imports, no detection, no special cases.
Awareness without coupling.
CLAUDE.md § Architecture: 2-line callout pointing to the brief, following
the existing "opt-in upstream architect plugin" precedent.
No Voyage behavior change. Documentation-only.
