HunterX Architecture Enforcement Framework

Status: Ratified (Sprint 006.7) Version: 1.0.0 Owner: HunterX Architecture Council

The Architecture Enforcement Framework encodes the ratified Clean Architecture rules from the Development Bible (docs/bible/02 - Architecture.md, docs/bible/03 - Folder Structure.md) as machine-checked, automatic validation. It catches boundary violations, forbidden imports and new dependency cycles at the earliest point in the workflow: the editor, the pre-commit hook, and CI.

This is enforcement only. It introduces no business logic and changes no mission behavior. Violations are reported, never silently fixed.

What it enforces

Check	Code	Fails CI?	Description
Dependency matrix	ARCH-001	Yes	A module imports a layer its layer is not allowed to reach
Forbidden imports	ARCH-002	Yes	Matches a forbidden pattern (legacy `core.`, `scripts.`, …)
Dependency cycles	ARCH-003	Yes	A new module-level import cycle (Tarjan SCC)
Plugin boundary	ARCH-004	Yes	A plugin imports something outside the public plugin SDK
Tool boundary	ARCH-005	Yes	A tool adapter imports something outside the tool SDK
Package docstring	ARCH-007	No	A package `__init__.py` lacks a docstring / recommended sections
Stability baseline	ARCH-009	Yes	Public API changed vs `config/api_baseline.json`
Expired waiver	ARCH-011	Yes	A recorded waiver outlived its deadline

Layering, import scanning, cycle detection, API snapshots and report rendering all live in src/hunterx/architecture/. The policy itself is data, not code: config/architecture.yaml is the single source of truth for every rule.

Quick start

pip install -e ".[all]"          # installs the hunterx-arch console script

hunterx-arch lint                # run every check; exit 1 on violations
hunterx-arch report              # write architecture-report.md (health score)
hunterx-arch matrix              # print the dependency matrix
hunterx-arch graph               # Mermaid layer diagram
hunterx-arch stability --generate  # refresh config/api_baseline.json

Governance

The matrix, waivers and known cycles in config/architecture.yaml may only be changed by the Architecture Council. Waivers are temporary by design: every waiver SHALL carry a deadline and SHALL fail CI once it expires (ARCH-011).
