Phase 0: make the site exist
Server-render the site; retitle the homepage to the mission, not the year; publish the stack diagram as clickable inline SVG; publish the scenario table wherever $5 trillion appears; file the trade mark for the whole “-TN” family at once.
Phase 1: the two assets
Eight engine pages and seven stack layer pages, cross-linked both ways; the Sub-Brand Gate published in full; the brand architecture; the evidence spine linked to Think TN.
Phase 2: the artefact and the convening
The first TN Stack Index with raw data downloadable; city-cluster pages; the Tamil door, professionally translated; summit.aitn.in/2027 opens with the Stack Index as its centrepiece.
The gate from Phase 2 to scale: the Stack Index has reported at least one layer going backwards, and survived doing so.
