Development Log — 2026-08-16 · Public Gateway v0.2

What happened

Expanded the single-page entrance into a multi-page public surface with an

anonymous public traffic channel.

  • Clean public routes: /, /architecture, /development-log, /research,

/status, /roadmap, plus a 404 page.

  • Shared public shell: one header, one footer, one navigation, one badge on

every page.

  • Design split into tokens / layout / components / pages (v0.1 baseline kept).
  • KAP public contracts under kap/ (site, navigation, content, traffic) —

declarative only, never an executable path into the core.

  • Traffic event contract: contracts/public-traffic-event.contract.json.
  • Anonymous traffic ingest: POST /api/public/traffic on a minimal Node

server (server/) with validation, privacy filtering, append-only storage

and in-memory rate limiting.

  • Summary generation: scripts/build-traffic-summary.js →

public-data/traffic-summary.public.json.

  • Content index generation: scripts/build-public-index.js now derives

articles, development-log and roadmap indexes from content/.

Verification

  • npm run build — content → public-data → web/public-data
  • npm run check — boundary + routes + navigation + contracts + validation

+ privacy tests

Next

  • Detail pages for /articles/<slug> and /development-log/<slug>.
  • Production deployment of the traffic ingest endpoint.
