chore(release): 0.0.3

Squash-merge lib-standardisation: adopt repo standards across packaging,
tooling, docs, and CI.

- standardize pyproject.toml (canonical packaging, lint config, extras, GSDFC pydoclint)
- add py.typed marker, modernize type hints and Google-style docstrings
- nest generated docs under docs/lib and docs/mcp; add hand-written wiki
- adopt standard Type A PyPI CI pipeline (tag==version guard + quality gate)
- promote generated CHANGELOG.md; bump version to 0.0.3

+# Drone standard — Type A: PyPI package
+#
+# Canonical pipeline for internal Python libraries that ship a wheel/sdist to
+# the private index (dagpipe, doc-forge, hexa, mail-intake, mongo-ops,
+# omniread, openapi-first, py-jwt).
+#
+# Two pipelines ship together:
+#   build-and-publish-pypi   — tag-triggered build + quality gate + publish.
+#   backfill-pypi-from-tags  — custom-triggered replay of every git tag that is
+#                              missing from the index (disaster recovery).
+#
+# Secrets (Drone): PIP_REPO_URL, PIP_USERNAME, PIP_PASSWORD.
+# Copy to <repo>/.drone.yml unchanged; the package name and version are read
+# from pyproject.toml, so no per-repo edits are required.
+#
+# Version guard: the tag build fails unless the git tag equals the version in
+# pyproject.toml (see the versioning standard). This stops a tag from looking
+# like a release while silently publishing nothing.

+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+## [0.0.3] - 2026-10-17
+
+### Added
+- `py.typed` marker for PEP 561 type information.
+- Hand-written wiki, plus doc-forge-generated API reference under `docs/lib`
+  and MCP bundle under `docs/mcp` (per-kind MkDocs configs).
+- MIT `LICENSE`.
+
+### Changed
+- Adopted the standard Type A PyPI CI pipeline: a `tag == version` guard and a
+  quality gate (black, ruff, mypy, pydoclint, pytest).
+- Standardized `pyproject.toml` (canonical packaging, lint tool config, extras)
+  with a shared Google-style `[tool.pydoclint]` configuration.
+- Google-style (GSDFC) docstrings across the public API; legacy typing
+  modernised to match signatures.
+- `fetch_emails.py` debug script excluded from black/ruff scans.
+
+### Fixed
+- Regression test for immutable config models raises `AssertionError` instead
+  of a bare `assert False`.
+- Stub fixes for typed API surfaces.

+# 🧱 Overview
+
+Mail Intake is a **contract-first ingestion pipeline**. Adapters handle
+transport to a provider, parsers normalize provider payloads, and the reader
+orchestrates the whole flow into canonical domain models.

+Layers:
+
+1. **Adapters** (`mail_intake.adapters`) — provider-specific, read-only
+   transport. Return provider-native payloads; never interpret them.
+2. **Auth** (`mail_intake.auth`) — credential acquisition and lifecycle
+   management, decoupled from adapters.
+3. **Credentials** (`mail_intake.credentials`) — persistence of auth tokens;
+   `PickleCredentialStore` locally, `RedisCredentialStore` for production.
+4. **Parsers** (`mail_intake.parsers`) — extract headers, body text, sender,
+   and normalized subjects from provider payloads.
+5. **Ingestion** (`mail_intake.ingestion`) — `MailIntakeReader` wires an
+   adapter + parsers into iterators over canonical models.
+6. **Models** (`mail_intake.models`) — provider-agnostic `MailIntakeMessage`
+   and `MailIntakeThread`.
+

+
+## 📦 Domain models
+
+`MailIntakeMessage`:
+
+| Field | Type | Meaning |
+|---|---|---|
+| `message_id` | `str` | Provider message id |
+| `thread_id` | `str` | Conversation thread id |
+| `timestamp` | `datetime` | Message timestamp |
+| `from_email` | `str` | Sender email |
+| `from_name` | `str \| None` | Sender display name |
+| `subject` | `str` | Message subject |
+| `body_text` | `str` | Extracted plain-text body |
+| `snippet` | `str` | Provider snippet |
+| `raw_headers` | `dict[str, str]` | Unmodified headers |
+
+`MailIntakeThread`:
+
+| Field | Type | Meaning |
+|---|---|---|
+| `thread_id` | `str` | Conversation id |
+| `normalized_subject` | `str` | Normalized subject (threads share one) |
+| `participants` | `set[str]` | Distinct senders |
+| `messages` | `list[MailIntakeMessage]` | Ordered messages |
+| `last_activity_at` | `datetime \| None` | Latest message time |
+

+
+## 🔒 Design guarantees
+
+- Read-only access — no mutation of provider state.
+- Provider-agnostic domain models.
+- Explicit configuration and dependency injection (no implicit env reads).
+- Extensible via public contracts; built-in adapters are reference
+  implementations and may change internally.

+# 🖥️ How to Use
+
+This page walks through authenticating, ingesting, and parsing mail with the
+built-in Gmail support.
+
+---
+
+## 🔐 Authentication
+
+Create a credential store and an auth provider:
+
+```python
+from mail_intake.auth import MailIntakeGoogleAuth
+from mail_intake.credentials import PickleCredentialStore, RedisCredentialStore
+
+store = PickleCredentialStore(path="token.pickle")          # local dev
+
+auth = MailIntakeGoogleAuth(
+    credentials_path="credentials.json",                    # your OAuth client file
+    store=store,
+    scopes=["https://www.googleapis.com/auth/gmail.readonly"],
+)
+```
+
+> OAuth credentials come from the Google Cloud Console and are provided via
+> file paths — never hard-code tokens or secrets in source. Once authorized,
+> the token is persisted by the credential store and refreshed automatically.
+
+For distributed deployments, use Redis instead of pickle:
+
+```python
+store = RedisCredentialStore(redis_client=redis_client)     # production
+```
+
+---
+
+## 📥 Ingesting messages
+
+Build an adapter and a reader, then iterate:
+
+```python
+from mail_intake.ingestion import MailIntakeReader
+from mail_intake.adapters import MailIntakeGmailAdapter
+
+adapter = MailIntakeGmailAdapter(auth_provider=auth)
+reader = MailIntakeReader(adapter)
+
+for message in reader.iter_messages("from:recruiter@example.com"):
+    print(message.subject, message.from_email, message.timestamp)
+```
+
+Access the full model:
+
+```python
+message.message_id    # provider id
+message.thread_id
+message.body_text     # plain-text body
+message.raw_headers   # unmodified headers dict
+```
+
+---
+
+## 🔖 Ingesting threads
+
+```python
+for thread in reader.iter_threads("subject:Interview"):
+    print(thread.normalized_subject)
+    print(thread.participants)
+    print(len(thread.messages))
+    print(thread.last_activity_at)
+```
+
+`MailIntakeThread` aggregates its messages, participants, and last activity.
+
+---
+
+## 🧪 Parsers
+
+Parsers normalize provider payloads and are used by the reader internally.
+They are also importable on their own:
+
+```python
+from mail_intake.parsers import extract_body, parse_headers, normalize_subject
+```
+
+- `extract_body(...)` — plain-text body extraction.
+- `parse_headers(...)` — structured header parsing.
+- `extract_sender(...)` — sender email/name extraction.
+- `normalize_subject(...)` — subject normalization for threading.
+
+---
+
+## ✅ Checklist
+
+1. Provide OAuth credentials via a file path and a credential store.
+2. Build the `MailIntakeGoogleAuth` provider with the Gmail read-only scope.
+3. Wrap the adapter in a `MailIntakeReader`.
+4. Consume `iter_messages` / `iter_threads`; never call provider APIs directly.

+# 🧩 Extending Mail Intake
+
+Mail Intake is designed to be extended through its **public contracts**.
+Implement your own adapter, auth provider, or credential store to support a
+new provider or storage backend.
+
+---
+
+## 📬 Custom adapters
+
+Subclass `MailIntakeAdapter` to integrate a new provider. Adapters perform
+read-only transport and return provider-native payloads:
+
+```python
+from mail_intake.adapters import MailIntakeAdapter
+
+class ExchangeAdapter(MailIntakeAdapter):
+    def __init__(self, auth_provider):
+        self._auth = auth_provider
+
+    def fetch_messages(self, query):
+        # call the provider API, return native payloads
+        ...
+
+    def fetch_threads(self, query):
+        ...
+```
+
+> **Do not** subclass built-in adapters like `MailIntakeGmailAdapter` — they
+> are reference implementations and may change internally without notice.
+
+---
+
+## 🔐 Custom auth providers
+
+Subclass `MailIntakeAuthProvider[T]` to own a different credential flow:
+
+```python
+from mail_intake.auth import MailIntakeAuthProvider
+
+class ExchangeAuth(MailIntakeAuthProvider[exchange_credentials]):
+    def get_credentials(self):
+        return self._store.load()
+
+    def refresh(self):
+        ...
+```
+
+Auth providers remain decoupled from adapter logic — they only manage
+credentials.
+
+---
+
+## 🗄️ Custom credential stores
+
+Implement the `CredentialStore[T]` contract for a new persistence backend:
+
+```python
+from mail_intake.credentials import CredentialStore
+
+class S3CredentialStore(CredentialStore):
+    def save(self, credentials):
+        ...
+
+    def load(self):
+        ...
+
+    def delete(self):
+        ...
+```
+
+The store abstraction keeps tokens out of config and rotates safely.
+
+---
+
+## 🧪 Wiring a custom backend
+
+```python
+from mail_intake.ingestion import MailIntakeReader
+
+auth = ExchangeAuth(store=S3CredentialStore(...))
+adapter = ExchangeAdapter(auth_provider=auth)
+reader = MailIntakeReader(adapter)
+
+for message in reader.iter_messages("query"):
+    print(message.subject)
+```
+
+The reader only depends on the adapter contract, so the rest of the pipeline
+keeps working unchanged.
+
+---
+
+## ✅ Extension checklist
+
+1. Implement the **public contract** — never subclass built-in adapters.
+2. Keep transport in the adapter, parsing in parsers, auth in the provider.
+3. Return the provider-native payload and let parsers normalize it.
+4. Inject dependencies explicitly — no global state or env reads.

+# 📬 Mail Intake — Provider-Agnostic Email Ingestion
+
+`Mail Intake` is a contract-first, read-only email ingestion framework. It
+pulls mail from external providers (such as Gmail), parses and normalizes it
+into clean, provider-agnostic domain models — ready to persist, index, or
+analyze downstream.
+
+> **Doc model:** this wiki is written for humans — how‑to guides and extension
+> recipes. The authoritative API contracts live in the code (GSDFC docstrings)
+> and the machine‑readable bundle under `docs/mcp/`.
+
+---
+
+## 🚀 Key Features
+
+* 📬 **Read-only ingestion** — never mutates provider state
+* 🧩 **Contract-first layers** — adapters, parsers, and readers separated
+* ✉️ **Provider-agnostic models** — `MailIntakeMessage` / `MailIntakeThread`
+  have no provider internals
+* 🔐 **Extensible auth** — pluggable auth providers and credential stores
+  (pickle for dev, Redis for production)
+* 🧪 **Deterministic & testable** — no implicit global state or env reads
+* 📊 **Gmail support** — reference adapter built on the official Google APIs
+
+---
+
+## ⚡ Quick Start
+
+```python
+from mail_intake.ingestion import MailIntakeReader
+from mail_intake.adapters import MailIntakeGmailAdapter
+from mail_intake.auth import MailIntakeGoogleAuth
+from mail_intake.credentials import PickleCredentialStore
+
+store = PickleCredentialStore(path="token.pickle")
+
+auth = MailIntakeGoogleAuth(
+    credentials_path="credentials.json",
+    store=store,
+    scopes=["https://www.googleapis.com/auth/gmail.readonly"],
+)
+
+adapter = MailIntakeGmailAdapter(auth_provider=auth)
+reader = MailIntakeReader(adapter)
+
+for message in reader.iter_messages("from:recruiter@example.com"):
+    print(message.subject, message.from_email)
