+# architecture-tests
+
+Executable enforcement of Packmind's hexagonal (ports & adapters) architecture,
+powered by [ArchUnitTS](https://github.com/LukasNiessen/ArchUnitTS).
+
+Each test is a rule about which layer may import which. Rules are expressed as
+import-dependency constraints over the real TypeScript source graph (aliases
+resolved via `tsconfig`), so a failure points at the exact offending file with a
+clickable path.
+
+## Why a separate command
+
+These tests are **not** part of `nx run-many -t test` / `npm run test:staged`.
+They scan the whole monorepo's dependency graph (slower) and they intentionally
+surface pre-existing violations as failures. Keeping them on a dedicated target
+avoids breaking the main suite while still giving the team a runnable
+architecture report.
+
+```bash
+npm run test:arch
+# = PACKMIND_EDITION=oss nx run architecture-tests:arch
+```
+
+The `arch` target first runs `scripts/build-arch-tsconfig.mjs`, which generates a
+self-contained `tsconfig.arch.json` (git-ignored) from the edition-aware
+`tsconfig.base.effective.json`. ArchUnitTS reads tsconfig with
+`ts.readConfigFile` (which does not follow `extends`), so it needs an inlined,
+include-bearing config — that is what the generator produces.
+
+## The workflow being enforced
+
+```
+NestJS controller → NestJS service → domain Adapter → UseCase
+  → application Service → repository interface (port) → repository implementation (infra)
+```
+
+Dependencies only ever point downward/inward. The rules below assert the
+forbidden shortcuts and back-edges.
+
+## Rules
+
+Rules live in `src/*.arch.spec.ts`. Layer selection globs are centralised in
+`src/architecture.ts` (tolerant of folder-naming variants such as
+`useCases`/`usecases` and `adapter`/`adapters`).
+
+### Core workflow layering — `src/layering.arch.spec.ts`
+
+| Rule                                              | Guards                                                                                                                                                       |
+| ------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| `infra/repositories` ↛ `application/**`           | Persistence must not depend upward on use cases/adapters/services.                                                                                           |
+| `application/useCases` ↛ `infra/repositories`     | Use cases reach data via services/ports, never concrete repositories. (`standard-use-case-architecture-patterns`)                                            |
+| `application/adapter(s)` ↛ `infra/repositories`   | "Never directly call Repositories in Adapter classes." (`standard-use-case-architecture-patterns`)                                                           |
+| `application/services` ↛ `infra/repositories`     | Services depend on repository **interfaces** (`domain/repositories`), not implementations.                                                                   |
+| `application/services` ↛ `application/useCases`   | Use cases orchestrate services, never the reverse — a service reaching back up inverts the layer.                                                            |
+| `application/services` ↛ `application/adapter(s)` | The adapter is the port entry point at the top of the layer; services below it must not depend back up.                                                      |
+| `apps/api` ↛ `infra/repositories`                 | No API file (controller, module, NestJS service) may reach concrete persistence — only ports. (`standard-nestjs-module-hierarchy`)                           |
+| `apps/api` ↛ `application/**`                     | The API reaches each domain only through its `@packmind/types` port (injected by port-name via the HexaRegistry), never use cases/services/adapter directly. |
+| `infra/schemas` ↛ `application/**`                | EntitySchema files are pure ORM mapping. (`infra/jobs` legitimately wires application jobs; schemas do not.)                                                 |
+
+### Domain purity — `src/domain-purity.arch.spec.ts`
+
+| Rule                           | Guards                                                               |
+| ------------------------------ | -------------------------------------------------------------------- |
+| `domain/**` ↛ `application/**` | The innermost ring must not know about the layer that depends on it. |
+| `domain/**` ↛ `infra/**`       | Domain stays free of infrastructure.                                 |
+
+### Cross-domain isolation — `src/cross-domain.arch.spec.ts`
+
+| Rule                                                                          | Guards                                                                                                                                                                                                                     |
+| ----------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `packages/<domain>/src` ↛ `packages/<other-domain>/src` (one rule per domain) | Domains collaborate only through `@packmind/types` ports wired by the HexaRegistry — never by importing each other's source. Complements the Nx `env:*` tag boundaries. (`standard-port-adapter-cross-domain-integration`) |
+
+Domains are **discovered**, not hardcoded: every package under `packages/` that
+owns a `src/domain/` layer is a domain (today: `accounts`, `spaces`, `standards`,
+`recipes`, `skills`, `git`, `deployments`, `coding-agent`, `llm`). Shared/leaf
+packages (`types`, `logger`, `node-utils`, `test-utils`, `migrations`, `editions`,
+`frontend`, `assets`, `linter-*`) have no `domain/` layer, so importing them stays
+legal for everyone. The only hardcoded list is `EXCLUDED_PACKAGES` in
+`src/architecture.ts`, which contains just `ui` (the Chakra frontend library — not
+a backend hexagon). A new domain package is therefore covered automatically.
+
+### Shared-package purity & reverse dependencies — `src/boundaries.arch.spec.ts`
+
+Between packages the graph is layered too:
+`apps/api → domain packages → @packmind/types (+ node-utils, logger)`.
+
+| Rule                                 | Guards                                                                                                          |
+| ------------------------------------ | --------------------------------------------------------------------------------------------------------------- |
+| `@packmind/types` ↛ any domain       | The contract package is a leaf — depending on a domain is a cycle and breaks "ports live in `@packmind/types`". |
+| `node-utils` / `logger` ↛ any domain | Base packages everything builds on must not depend back on a domain.                                            |
+| any domain ↛ `apps/api`              | Reverse dependency: the API consumes domains, never the other way round.                                        |
+
+## Known violations (tech debt)
+
+At their introduction, **16 of 23 rules passed** and **7 failed** — the
+violations listed below. Failures are real and left visible on purpose: each is either
+fixed by refactoring the offending import or accepted as tracked debt. (As these
+imports are refactored, the corresponding entries below stop failing.)
+
+**Core layering**
+
+- `infra/repositories ↛ application` — `coding-agent` `PackmindDeployer` imports
+  `CommandsIndexService` and `StandardsIndexService`.
+- `useCases ↛ infra/repositories` — three `git` use cases import
+  `GithubTokenResolverFactory` (`addGitProvider`, `updateGitProvider`,
+  `shared/validateProviderCredentials`).
+- `adapter ↛ infra/repositories` — `git` `GitAdapter` → `GithubTokenResolverFactory`;
+  `llm` `LlmAdapter` → `AIProviderRepository`.
+- `services ↛ infra/repositories` — `recipes` `RecipeService` and
+  `RecipeVersionService` import their concrete repositories directly.
+
+**Domain purity**
+
+- `domain ↛ application` — `domain/jobs/*DelayedJobs` interfaces import concrete
+  `application/jobs/*DelayedJob` classes in `deployments`, `git`, `recipes` (×2)
+  and `standards`.
+- `domain ↛ infra` — `coding-agent` `ICodingAgentDeployer` imports
+  `DefaultSkillsDeployer`.
+
+**Cross-domain**
+
+- `deployments` imports `coding-agent`, `recipes`, `skills`, `spaces` and
+  `standards` directly (use cases / `DefaultSkillsMetadataEnricher` →
+  `coding-agent`; `PackageRepository` → the four others). The other seven domains
+  are cleanly isolated.
+
+Standards referenced above live under
+`packages/.claude/rules/packmind/` and `apps/api/.claude/rules/packmind/`.
