ci: enterprise-shaped-scenarios quarantined — dataclass collection error blocks all tests under enterprise-execution-readiness/

[LalaSkye]

Symptom

enterprise-shaped-scenarios.yml has failed on every run since 2026-05-12 (10/10 reds). All 4 tests under enterprise-execution-readiness/tests/ error at pytest collection with AttributeError: 'NoneType' object has no attribute '__dict__' originating from a @dataclass decoration in enterprise-execution-readiness/adapters/replay_ledger.py:14 under Python 3.11.15 (dataclasses.py:712, _is_type).

Affected

• enterprise-execution-readiness/tests/test_esp_001_email_no_send.py
• enterprise-execution-readiness/tests/test_esp_001_real_gate_bridge.py
• enterprise-execution-readiness/tests/test_real_commit_gate_replay_semantics.py
• enterprise-execution-readiness/tests/test_replay_after_denial.py

Scope decision

enterprise-execution-readiness/ is not part of the v0.1.0 proof surface. Workflow is being quarantined to workflow_dispatch only (see PR-A) so that v0.1.0 release hygiene (PR-B) can proceed against a fully green main.

Fix scope (out of band)

Diagnose the dataclass field in replay_ledger.py that resolves to None during class construction. Likely candidates: a forward-ref under from __future__ import annotations, a KW_ONLY sentinel with a missing import, or a field(default_factory=...) referencing a name not yet bound. Fix in its own branch against a green main.
