Ryth Azhur 787f90fd12 Flatten to three packages + extract mizan-runtime
packages/
  mizan-runtime/   Framework-agnostic state engine (~150 lines)
                   Context registry, batched invalidation, fetch primitives
  mizan-django/    Django server adapter (was packages/mizan-rpc/adapters/django/)
                   Codegen moved to mizan-django/generate/
  mizan-react/     React adapter (was packages/mizan-csr/adapters/react/)

Removed premature abstractions: mizan-ast, mizan-schema, mizan-rpc,
mizan-csr, mizan-ssr stub packages. The actual architecture is three
concrete packages, not five abstract layers.

mizan-runtime implements the v1 spec: registerContext with params,
scoped invalidation via microtask batching, server-driven invalidation
from mutation responses, mizanFetch for context bundles, mizanCall for
mutations.

264 Django + 33 React tests pass.

# mizan (Python)
Django server functions framework. See the [monorepo root](../README.md) for full documentation.
## Install
```bash
uv add "mizan[channels,allauth] @ git+https://git.impactsoundworks.com/isw/mizan.git#subdirectory=django"
```
## Setup
```python
# settings.py
INSTALLED_APPS = ["mizan", ...]
# urls.py
path("api/mizan/", include("mizan.urls"))
# asgi.py (optional, for WebSocket)
from mizan import wrap_asgi
application = wrap_asgi(get_asgi_application())
```
## Define Functions
```python
from mizan.client import client
from mizan.setup.registry import register
from pydantic import BaseModel
class Output(BaseModel):
message: str
@client
def echo(request, text: str) -> Output:
return Output(message=text)
register(echo, "echo")
```
Register in `apps.py`:
```python
def ready(self):
import myapp.mizan_clients
```
## Auth
```python
@client(auth=True) # requires authentication
@client(auth='staff') # requires is_staff
@client(auth='superuser') # requires is_superuser
@client(auth=my_callable) # custom check
```
## Contexts
```python
@client(context='global') # fetched once, SSR-hydrated, becomes useCurrentUser()
@client(context='local') # fetched with params, becomes <GreetProvider>
```
## Forms
```python
from mizan.forms import mizanFormMixin, mizanFormMeta
class ContactForm(mizanFormMixin, forms.Form):
mizan = mizanFormMeta(name="contact", title="Contact Us")
name = forms.CharField()
email = forms.EmailField()
def on_submit_success(self, request):
return {"sent": True}
```
Auto-registers `contact.schema`, `contact.validate`, `contact.submit`. Generates `useContactForm()` with Zod validation.
## Channels
```python
from mizan.channels import ReactChannel
class ChatChannel(ReactChannel):
class Params(BaseModel):
room: str
class DjangoMessage(BaseModel):
text: str
def authorize(self, params):
return self.user.is_authenticated
def group(self, params):
return f"chat_{params.room}"
```
Generates `useChatChannel({ room })`.
## Running Tests
```bash
uv sync --extra dev --extra channels
uv run pytest
```
