+name: qa-create-test
+description: Scaffold and wire a new end-to-end test into the CodeZero QA framework at reticulum/qa (Ruby/RSpec/Capybara, GitLab-QA style). Use when asked to "add a QA test", "write a reticulum e2e/QA test", "add a spec for <flow/project/action/...>", or to extend the resource/page/spec layers. Produces a GraphQL resource factory and/or a sculptor page object plus an RSpec feature spec, correctly tagged and autoloaded.
+---
+
+# Add a test to the CodeZero QA framework
+
+The framework lives in `reticulum/qa`. It drives a **running** deployment (nginx → sculptor
+UI + sagittarius GraphQL + the nats/aquila/taurus/action runtime). Read `qa/README.md` first —
+it is the authoritative contract (layers, env vars, `data-qa-selector` groups).
+
+Three layers: **Resource** (`qa/qa/resource/`, GraphQL API factories — arrange state & assert
+backend/runtime), **Page** (`qa/qa/page/`, Capybara page objects over `data-qa-selector`), and
+**Specs** (`qa/specs/features/<category>/<name>_spec.rb`).
+
+## Decision rule (which layer)
+
+- **Arrange + assert via the API** (resource layer). It is fast and deterministic: create the
+  org/namespace/project/flow/runtime you need, and read back state (runtime status, execution
+  result, definitions) to assert.
+- **Act via the UI** (page layer) only for the capability the spec is actually about — the thing
+  a user does in sculptor. Tag such specs `:browser`.
+- A pure-API spec is tagged `:api`; a spec that mixes UI actions with API setup/assertions is
+  tagged `:orchestrated`. Add `:smoke` to the handful of critical-path specs.
+
+## Step-by-step
+
+1. **Pick the scenario + category.** Choose `<category>` (e.g. `project`, `flow`, `actions`) and
+   the `product_group:` metadata (e.g. `:project`, `:flow`, `:authentication`). Create
+   `qa/specs/features/<category>/` if missing.
+
+2. **Resource (if you need to create/read backend state).** Copy `templates/resource.rb.template`
+   to `qa/qa/resource/<name>.rb`. Follow `qa/qa/resource/project.rb` exactly:
+   - attributes via `attr_accessor`;
+   - `#api_create` returns `[graphql_string, variables_hash]`;
+   - `#process_create_response(data)` populates `@id` and any read-back fields;
+   - `#api_delete` returns `[graphql_string, variables_hash]` for cleanup.
+   - **Find the mutation name**: it is the Sagittarius mutation class path with `Mutations::`
+     dropped, `::` removed, first letter lower-cased. Confirm by reading
+     `/Users/raph/Documents/Code0/sagittarius/app/graphql/mutations/**`. Examples:
+     `Mutations::Namespaces::Projects::Create` → `namespacesProjectsCreate`;
+     `Mutations::Organizations::Create` → `organizationsCreate`;
+     `Mutations::Namespaces::Projects::Flows::TriggerExecution` → `namespacesProjectsFlowsTriggerExecution`.
+     (Rule source: `base_mutation.rb` `graphql_name subclass.name.delete_prefix('Mutations::').gsub('::','')`.)
+   - Get the **arguments and input/ID types** from the same mutation file (e.g. `NamespaceID!`,
+     `NamespaceProjectID!`). Every mutation returns `errors { message }` — always select it; the
+     base class raises on a non-empty `errors` array.
+
+3. **Page object (if the spec performs a UI action).** Copy `templates/page.rb.template` to
+   `qa/qa/page/<area>/<name>.rb`. Follow `qa/qa/page/auth/login.rb`:
+   - declare `path "/..."` and `view_selectors %w[...]`;
+   - expose intention-revealing methods built from `Page::Base` helpers
+     (`fill_element`, `click_element`, `has_element?`, `has_element_with_text?`,
+     `wait_for_element`, `wait_until`).
+   - **Discover real selectors** from the sculptor source (never guess):
+     `grep -rhoE 'data-qa-selector=\{?"[^"]+"' <sculptor>/src | sed -E 's/.*"([^"]+)"/\1/' | sort -u`
+     Known groups are listed in `qa/README.md` (auth / dashboard / flow-builder / flow-create).
+
+4. **Register autoloads** in `qa/qa.rb`: add `autoload :<Const>, "qa/resource/<name>"` under
+   `module Resource`, and/or `autoload :<Const>, "qa/page/<area>/<name>"` under the matching
+   `Page::<Area>` module (create the nested `module <Area>` if new).
+
+5. **Spec.** Copy `templates/spec.rb.template` to `qa/specs/features/<category>/<name>_spec.rb`.
+   Follow `qa/specs/features/login/login_spec.rb`:
+   - `RSpec.describe "<Area>", product_group: :<group> do` with a layer tag;
+   - fabricate prerequisites with `QA::Resource::X.fabricate_via_api!`;
+   - do the one thing under test (UI via a page object, or API);
+   - assert via UI (`have_css([data-qa-selector="..."])`) and/or API (`QA::Resource` read / client query);
+   - clean up in an `after` block with `remove_via_api!` (guard with `&.`).
+
+6. **Verify.**
+   ```sh
+   cd reticulum/qa
+   ruby -c qa/qa/resource/<name>.rb && ruby -c qa/qa/page/<area>/<name>.rb && ruby -c qa/specs/features/<category>/<name>_spec.rb
+   bundle exec rspec qa/specs --dry-run        # new example(s) must appear in the list
+   ```
+   A real run needs a live deployment: `QA_SEED=true QA_DEPLOYMENT=docker-compose QA_BASE_URL=... bin/qa qa/specs/features/<category>/<name>_spec.rb`.
+
+## Rules
+
+- Never invent GraphQL fields, mutation names, or `data-qa-selector` values — read them from
+  `sagittarius/app/graphql` and the sculptor source.
+- Keep browser specs minimal and resilient (selectors only, generous waits via `wait_for_element`).
+- Always select `errors {
+                errorCode
+                details {
+                  ...on ActiveModelError { attribute type }
+                  ...on MessageError { message }
+                }
+              }` in every mutation and always add cleanup.

+# CodeZero QA — end-to-end test framework
+
+End-to-end (E2E) tests for the CodeZero platform, modelled on the
+[GitLab QA framework](https://gitlab.com/gitlab-org/gitlab/-/tree/master/qa).
+
+The suite drives a **running** CodeZero deployment (the full stack that `reticulum`
+packages: nginx → sculptor / sagittarius, and the nats → aquila → taurus → action
+runtime). It is deliberately decoupled from the build so the exact same specs run
+against a locally booted `docker-compose` stack, the `terraform/docker` stack, or a
+remote environment such as staging.
+
+## How a test is shaped
+
+Three layers, same idea as GitLab QA:
+
+1. **Resource layer** (`qa/resource/`) — API factories over Sagittarius GraphQL
+   (`POST /graphql`). Create/read/delete orgs, namespaces, projects, flows, runtimes,
+   actions. This is how a test arranges state cheaply and how it makes *backend* and
+   *runtime* assertions (runtime status, execution results, module/function definitions).
+2. **Page layer** (`qa/page/`) — Capybara page objects over the sculptor UI. This is the
+   GitLab-style "open a page and do stuff" layer. sculptor annotates interactive elements
+   with **`data-qa-selector="<name>"`** (90+ across auth / dashboard / flow-builder), so page
+   objects reference those stable names — never CSS/text. Page objects use the `*_element`
+   helpers in `Page::Base`, which build `[data-qa-selector="..."]` queries. The resource
+   layer still arranges prerequisites and makes the backend/runtime assertions.
+
+   Known selector groups (see `data-qa-selector` in sculptor for the authoritative list):
+   - **auth**: `auth-login-{email,password,send}`, `auth-register-*`, `auth-complete-profile-*`,
+     `auth-email-*`, `auth-password-*`
+   - **dashboard**: `dashboard-navigation`, `dashboard-namespace-*`,
+     `dashboard-organization-create-{name,send}`,
+     `dashboard-namespace-project-create-{name,description,send}`, `dashboard-project-*`,
+     `dashboard-flow-*`
+   - **flow builder**: `flow-builder-{canvas,node,trigger,tabs,parameter,setting}`,
+     `flow-builder-control-panel-{add,delete,execute}`,
+     `flow-builder-manual-execution-{form,input,trigger}`
+   - **flow create**: `flow-create-{form,name,send,list,template-mode,...}`
+3. **Specs** (`qa/specs/features/`) — RSpec feature specs that compose the two layers.
+
+A typical spec: fabricate prerequisites via the API, do the one thing under test (via UI
+or API), then assert via GraphQL and/or the runtime.
+
+## Running
+
+```sh
+cd qa
+bundle install
+bin/qa                      # run the whole suite against QA_BASE_URL
+bin/qa --tag smoke          # only smoke-tagged specs
+bin/qa qa/specs/features/login/login_spec.rb   # one file
+```
+
+### Environment variables (all consumed by `QA::Runtime::Env`)
+
+| Variable | Default | Meaning |
+|---|---|---|
+| `QA_BASE_URL` | `http://localhost` | Base URL of the deployment under test (nginx front door). UI at `/`, GraphQL at `/graphql`. |
+| `QA_GRAPHQL_PATH` | `/graphql` | GraphQL endpoint path. |
+| `QA_USER_EMAIL` | `root@code0.tech` | Login email for the QA user (the stack's native `INITIAL_ROOT_MAIL`). |
+| `QA_USER_PASSWORD` | `root` | Login password (`INITIAL_ROOT_PASSWORD`). |
+| `QA_USER_USERNAME` | `root` | Username (login accepts email **or** username). |
+| `QA_RUNTIME_TOKEN` | `runtime` | Token the seeded runtime authenticates with (`INITIAL_RUNTIME_TOKEN`). |
+| `QA_SEED` | `false` | When `true`, seed the QA user + runtime before the suite. **Not needed for docker-compose** — the stack self-seeds on boot from the `INITIAL_*` env; only for environments without native seeding. |
+| `QA_DEPLOYMENT` | `external` | `docker-compose` \| `terraform` \| `external`. Selects how seeding runs. |
+| `QA_COMPOSE_DIR` | `../docker-compose` | Where `docker compose` is invoked for seeding (deployment `docker-compose`). |
+| `QA_BROWSER` | `chrome` | Selenium browser. |
+| `QA_HEADLESS` | `true` | Headless Chrome. |
+| `QA_SELENIUM_URL` | _(none)_ | Remote Selenium/WebDriver URL (e.g. a `selenium/standalone-chrome` service in CI). When unset, a local driver is used. |
+| `QA_WEBDRIVER_INSECURE` | `true` | Accept self-signed certs (the docker-compose stack serves HTTPS with a self-signed cert). |
+| `QA_SCREENSHOTS_DIR` | `tmp/screenshots` | Where failure screenshots/HTML are written. |
+| `QA_LOG_LEVEL` | `info` | `debug` \| `info` \| `warn` \| `error`. |
+
+## Public contract (what each layer looks like — follow these when adding code)
+
+### `QA::Runtime::ApiClient`
+```ruby
+client = QA::Runtime::ApiClient.new            # reads QA_BASE_URL etc. from Env
+token  = client.login!                         # userLogin mutation -> stores session token
+data   = client.query(<<~GQL, variables: { id: project_id })
+  query($id: ProjectID!) { ... }
+GQL
+```
+`#query`/`#mutate` return the parsed `data` hash and raise `QA::Runtime::ApiClient::Error`
+on transport errors or a non-empty GraphQL `errors` array.
+
+### `QA::Resource::Base`
+Subclass and implement the create/delete GraphQL. Factory usage:
+```ruby
+project = QA::Resource::Project.fabricate_via_api! do |p|
+  p.name = "qa-#{SecureRandom.hex(4)}"
+  p.namespace = namespace
+end
+project.remove_via_api!
+```
+A subclass implements:
+- attributes via `attr_accessor`
+- `#api_create` → `[graphql_string, variables_hash]`
+- `#process_create_response(data)` → populate `@id` etc. from the mutation result
+- `#api_delete` → `[graphql_string, variables_hash]` (optional; default no-op)
+See `qa/resource/project.rb` as the reference implementation.
+
+### `QA::Page::Base`
+Subclass per page. Capybara DSL plus resilient helpers
+(`fill_in_field`, `click_button_text`, `wait_until`, `has_element_text?`).
+Each page declares a `path` and `#on_page?`. See `qa/page/auth/login.rb` as the reference.
+
+### Specs
+Live in `qa/specs/features/<category>/<name>_spec.rb`. Tag every spec with a
+scenario area and one of `:api` / `:browser` / `:orchestrated`:
+```ruby
+RSpec.describe 'Tenant scale', :orchestrated, product_group: :project do
+  it 'creates a project', :smoke do
+    ...
+  end
+end
+```
+See `qa/specs/features/login/login_spec.rb` as the reference.
+
+## Deployment matrix & CI
+
+The GitLab CI `qa:*` jobs boot each deployment option, seed it (`QA_SEED=true`), then run
+the suite. The same jobs accept `QA_BASE_URL` pointing at an already-running environment
+(no build, no seed) — that is the "run against staging" mode. See `.gitlab/ci/qa.gitlab-ci.yml`.
+
+## Adding a test
+
+Use the `qa-create-test` skill (`.claude/skills/`) — it scaffolds the resource, page object
+and spec from the references and wires the tags.
