-Extensibility Model
+
-----------------------------------------------------------------------
+## Architecture
 
 Mail Intake is designed to be extensible via **public contracts** exposed
 through its modules:
 
-- Users MAY implement their own mail adapters by subclassing
+- Users MAY implement their own mail adapters by subclassing ``adapters.MailIntakeAdapter``
-  `adapters.MailIntakeAdapter`
+- Users MAY implement their own authentication providers by subclassing ``auth.MailIntakeAuthProvider[T]``
-- Users MAY implement their own authentication providers by subclassing
+- Users MAY implement their own credential persistence layers by implementing ``credentials.CredentialStore[T]``
-  `auth.MailIntakeAuthProvider`
 
 Users SHOULD NOT subclass built-in adapter implementations. Built-in
 adapters (such as Gmail) are reference implementations and may change
 internally without notice.
 
-----------------------------------------------------------------------
+**Design Guarantees:**
-Public API Surface
+- Read-only access: no mutation of provider state
-----------------------------------------------------------------------
+- Provider-agnostic domain models
+- Explicit configuration and dependency injection
+- No implicit global state or environment reads
+- Deterministic, testable behavior
+- Distributed-safe authentication design
+
+Mail Intake favors correctness, clarity, and explicitness over convenience
+shortcuts.
+
+**Core Philosophy:**
+`Mail Intake` is built as a **contract-first ingestion pipeline**:
+1. **Layered Decoupling**: Adapters handle transport, Parsers handle format normalization, and Ingestion orchestrates.
+2. **Provider Agnosticism**: Domain models and core logic never depend on provider-specific (e.g., Gmail) API internals.
+3. **Stateless Workflows**: The library functions as a read-only pipe, ensuring side-effect-free ingestion.
