# Context Builders -- Technical Specification

**Version**: v1.0.0 | **Status**: Active | **Last Updated**: March 2026

## Overview

Placeholder submodule for template context construction utilities. Intended to provide builders that assemble variable dictionaries for template rendering.

## Architecture

This submodule is currently a namespace placeholder. The `__init__.py` exports an empty `__all__` list. Context construction logic is handled inline by the parent `templating` module and sibling submodules (`engines`, `loaders`).

## Current State

- `__init__.py`: Module docstring and empty `__all__` -- no classes or functions implemented yet.
- Future scope: context builder classes for assembling template variables from data sources, environment, and configuration.

## Planned Interface

When implemented, the module would expose:

| Class / Function | Purpose |
|-----------------|---------|
| `ContextBuilder` | Fluent API for assembling template variable dictionaries |
| `ContextStack` | Layered context with parent/child scoping |

## Dependencies

- **Internal**: `templating.engines` (consumers of context dicts)
- **External**: none

## Constraints

- Not yet implemented; importing yields an empty namespace.
- Zero-mock: `NotImplementedError` for unimplemented paths.

## Navigation

- [README.md](README.md) | [AGENTS.md](AGENTS.md)
- Parent: [templating](../README.md)
