Platform architecture

Blueprint for scalable AI

How dex28 stays coherent from the gateway to your storage tier — with the same visual language we call The Architect.

Runtime flow

Traffic moves predictably through the stack:

  1. Gateway — auth, rate limits, request shaping
  2. Custom logic — your routers, tools, rubrics, retrieval
  3. Proxied LLMs & perception — unified quotas and telemetry
  4. Storage & queues — durable artifacts, replay, and burst absorption

Benefit: engineered for any scale — RBAC enforces governance across every solution surface, from internal APIs to customer-facing agents.

Design system · overview

Surfaces use square geometry (no border radius) for a rigid control-plane read: strong type scales, asymmetry, and a high-contrast foundation.

Technical tone is conveyed with fine lines, 48px grid rhythm, and restrained motion.

Colors

Material-style tokens (examples):

  • background / surface · #131313
  • primary · #ffffff · on-primary · #1a1c1c
  • secondary · #c6c6c6
  • error · #ffb4ab · outline-variant · #474747

No-line rule: prefer tonal surfaces. Ghost borders: outline-variant at low opacity when containment is required.

Typography

  • Space Grotesk — display, labels.
  • Inter — body copy at comfortable line height (~1.6).

Elevation & depth

Stack surface tiers: lowest for recessed panels, highest for lifted chips. Glass on nav via backdrop blur.

Components

  • Primary button: solid primary, ~0.25rem radius; hover to primary-container in ~150ms.
  • Secondary: ghost control on outline-variant at low opacity.
  • Technical grid: 48px intervals.

Do

  • Generous whitespace; 12-column grid.
  • Subtle motion when purposeful.

Don’t

  • Large radii or playful pills for core chrome.
  • Non-monochrome accents except errors.
