# MSB Architecture

Mega-Super-Base (MSB) is an architecture for Python applications built around a single entry
point. You describe your data as typed entities, you describe what may be done to them as
operations, and everything reaches both through one orchestrator — a user, a GUI, another
API, whatever drives the application.

A request is data, not a call:

```text
{"operation": "configure", "obj": telescope, "attributes": {"set_diameter": 64.0}}
```

which is what lets the same code serve a dialog box, a script and a remote caller, and what
lets a session be logged and replayed.

## Features

- **Typed entities**: attributes validated against their annotations, nested to any depth,
  including `List`, `Dict`, `Tuple`, `Set`, `Union`, `Literal`, `Callable` and `Type[X]`.
- **Constraints on values, not just types**: `price: Annotated[float, Positive()]` is enforced
  on construction, on assignment and on restore, with no `__init__` of your own.
- **Containers for collections**: named, queryable, serializable, with bulk operations.
- **One entry point**: a `Manipulator` registers operations and processes requests; the
  per-operation facades are sugar so you rarely write a request dictionary by hand.
- **Reading and writing come free**: `inspect` and `configure` are supplied, so an application
  that only reads and writes its model needs no operation layer at all.
- **Operations that write themselves**: a handler is usually one call to `_apply_methods`,
  which applies everything a request names and reports each outcome.
- **Serialization that round-trips**: `json.loads(json.dumps(obj.to_dict()))` restores an
  equal object, through lists, dicts, sets and tuples, for entities nested to any depth.
  Cycles are detected rather than followed, and serialized data carries the version of the
  class that wrote it, so a model can change shape and still read its old files.
- **Logging that behaves**: a dedicated `msb_arch` logger that stays silent until the
  application configures it.
- **Exceptions you can catch precisely**: everything derives from `MSBError`, and also from
  the built-in it replaces, so `except TypeError` keeps working while `except
  DuplicateNameError` becomes possible.
- **One place to hang metrics, auditing, rate limiting and authorisation**: an interceptor sees
  a request before it runs and its response after, and may refuse or rewrite it. Request
  metrics and a replayable request journal ship using nothing more than that hook.
- **Asynchronous when you need it**: `await manipulator.ainspect(...)` keeps an event loop
  responsive by moving the work off it, and every synchronous signature is untouched.
- **No external dependencies**: Python >= 3.12 and nothing else.

## Installation

```bash
pip install msb_arch
```

## Quick Start

Describe the data, describe the operations, drive both through the orchestrator.

```python
from msb_arch import BaseContainer, BaseEntity, Manipulator

# 1. the data
class Telescope(BaseEntity):
    diameter: float

    def get_diameter(self) -> float:
        return self.diameter

    def set_diameter(self, value: float) -> bool:
        self.diameter = value
        return True

class Telescopes(BaseContainer[Telescope]):
    pass

# 2. the entry point
class Observatory(Manipulator):
    pass

manipulator = Observatory(base_classes=[Telescope, Telescopes])

dishes = Telescopes(name="array")
dishes.add(Telescope(name="DSS14", diameter=70.0))
dish = dishes.get("DSS14")

manipulator.inspect(dish, get_diameter=None)      # 70.0
manipulator.configure(dish, set_diameter=64.0)
manipulator.inspect(dish, get_diameter=None)      # 64.0

dishes.to_dict()["items"]["DSS14"]["diameter"]    # 64.0
```

There is no operation layer to write: `inspect` and `configure` follow from the request model
itself, so the framework supplies them, and they serve every type. You write a `Super` when an
operation carries domain logic — `calculate`, `visualize` — and register it the same way.

```python
from msb_arch import Super

class Calculator(Super):
    OPERATION = "calculate"

    def _calculate_telescope(self, obj, attributes):
        return self._apply_methods(obj, attributes)

manipulator.register_operation(Calculator(manipulator))
```

A handler is one line because `_apply_methods` owns the loop, and the orchestrator dispatches
by operation and by the type of the object, so adding an entity adds no code at all.

Ask for several things at once and every outcome comes back, whatever the order:

```python
manipulator.inspect(dish, get_diameter=None, get=["name", "isactive"])
# {'get_diameter': {'status': True, 'result': 64.0},
#  'get':          {'status': True, 'result': {'name': 'DSS14', 'isactive': True}}}
```

Run several requests as one batch:

```python
manipulator.batch([
    {"operation": "configure", "obj": dish, "attributes": {"set_diameter": 70.0}},
    {"operation": "inspect", "obj": dish, "attributes": {"get_diameter": None}},
])
```

## Architecture

Four modules, three layers.

| Layer | Module | What lives there |
| --- | --- | --- |
| **Base** — the data | [`serializable.py`](src/msb_arch/base/serializable.py), [`baseentity.py`](src/msb_arch/base/baseentity.py), [`basecontainer.py`](src/msb_arch/base/basecontainer.py) | Validation, serialization, caching, ownership |
| **Super** — the operations | [`super.py`](src/msb_arch/super/super.py), [`project.py`](src/msb_arch/super/project.py) | Handlers, method resolution, projects |
| **Mega** — the entry point | [`manipulator.py`](src/msb_arch/mega/manipulator.py) | Operation registry, request processing, facades, batches |
| Shared | [`results.py`](src/msb_arch/results.py), [`utils/`](src/msb_arch/utils) | Result types, logging, validation helpers |

Main classes:

- **`Serializable`** — what an entity and a container have in common: annotated fields and
  their validation, `name` and `isactive`, `to_dict`, the cache. Use it in `isinstance`
  checks that should accept either.
- **`BaseEntity`** — an object addressed by its attributes.
- **`BaseContainer[T]`** — a named collection addressed by its items. A sibling of
  `BaseEntity`, not a subclass: an entity and a container mean different things by `get`,
  `set` and `clear`.
- **`Super`** — an operation. Subclass it, name the operation, and write handlers as
  `_<operation>_<type>` or `_<operation>` for the fallback.
- **`Project`** — a named collection of entities with a factory for creating them.
- **`Manipulator`** — the entry point. Registers operations, processes requests, generates a
  facade per operation.
- **`MethodResults`** — what an operation reports: every method it ran, mapped to its
  outcome.

## Testing

Unit, integration, performance and concurrency suites, run with pytest.

The tests import `msb_arch` rather than the source tree, so they exercise whatever is
installed. Install the package first:

```bash
pip install -e .
```

Then run them:

```bash
pytest tests/
```

CI builds the wheel, installs it, checks that `msb_arch` resolves inside `site-packages`,
and runs the same suites against it — so the distribution that ships is the one that was
tested.
