Technical Intelligence

This layer covers every repo, shared package, piece of infrastructure, and cross-repo integration pattern in the 7Mind system. Agents should read their own repo note before any significant task, and consult integration notes when a change spans multiple repos.

Repos

One file per repository. Named to match the GitHub repo slug exactly.

• 7mind-mobile-apps-monorepo — iOS/Android 7Mind app (Flutter monorepo)
• elixir-backend — primary API and business logic (Elixir)
• nuxt-website — marketing and web app (Nuxt SSR)
• api-contracts — shared API type definitions and contracts

Add additional repo notes here as they are created.

Shared NPM Packages

• (none documented yet — add pkg-*.md files as packages are catalogued)

Infrastructure

• infra-overview — high-level system topology
• google-cloud — GCP projects, regions, services
• cloudflare — DNS zones, routing rules, Workers, Pages
• github-actions — pipeline topology, deploy flows, secrets conventions
• terraform — module layout, state backend, conventions

Concepts

System-wide architectural patterns and service configurations that span multiple repos or require cross-cutting context. Read these before editing code that touches the named concern.

• modulith-domain-model — domain isolation, per-domain databases, event-only coupling (elixir-backend)
• dual-brand-routing — how one backend serves both 7Mind and 7Sleep
• supertokens-auth — JWT auth via SuperTokens + Cloudflared, how validation works
• chargebee-billing — subscription billing, dual namespaces for 7Mind vs 7Sleep
• typespec-contracts — TypeSpec-authored API contracts, OpenAPI emit, Redoc publishing pipeline
• api-versioning-headers — version negotiation via user-agent and accept headers across all clients
• mobile-deep-linking — URL schemes, Adjust shortlink resolution, Aury webview route alias
• mobile-analytics-stack — Rudderstack / Adjust / Braze / Sentry / ConfigCat / Amplitude on the mobile app
• aury-companion — the two distinct meanings of “Aury” in the 7Mind system
• storyblok-cms — headless CMS powering marketing pages, magazin, and dynamic routes on the web
• multi-domain-hostname-rewriting — how the web SSR build serves 7mind.de / 6mind.de / 8mind.de / 9mind from one image
• theme-build-multiplexing — THEME build arg producing separate 7Mind/7Sleep frontend images from one codebase

Integrations

Cross-repo connection patterns. Add notes here when a multi-repo interface is non-obvious.

• backend-event-bus — Google Pub/Sub + Broadway as the async event spine connecting backend domains
• mobile-build-pipeline — Codemagic owns mobile production builds, GitHub Actions handles CI
• locale-aware-slugs-static-export — replicating Nuxt’s nuxtI18n.paths per-locale URL slugs in a Next.js Pages-Router static export (website-next-js port)
• static-export-i18n-catalogue — loading the 450 KB locale catalogue at build time and keeping it out of the client bundle; distributing slices via getStaticProps + a React context (website-next-js port)
