Engineering Method 0.1.0

Engineering Method 0.1.0 is the first stable release for Codex and Claude.

• Shared Spec Kit and OpenSpec workflows, adapted debugging/TDD/review practices, durable backlog and continuity state, and an architecture/UML gate.
• English installation, maintenance, migration, usage and contribution documentation.
• Corrected native skill-read evidence collection, including Claude terminal-newline normalization.

Validation: 308 tests, portable and Claude strict validation, three pinned upstream provenance checks, deterministic packaging, and native clean installation on both hosts passed. Runtime code, skill instructions, adapters and fixtures are unchanged from accepted baseline 0784c79; the release updates documentation and the empty feature-inventory template caption.

Complete original gate coverage was independently accepted: 24 routing cases and both ten-phase architecture fixtures, using Astra and Fable at low effort. This acceptance explicitly reuses same-package evidence and includes a Claude checkpoint instruction supplement and one verified ownership-report correction. It does not claim a successful single full release-check invocation; original failed reports remain preserved.

Limits: verified host versions are Codex CLI 0.153.4 and Claude Code 2.1.259 on macOS. Native Codex recovery in the unborn fixture repository was not proven; continuity has script-test coverage. Model compliance is not guaranteed. Mermaid validation is semantic, not rendered. See the acceptance record.

The earlier v0.1.0-rc.1 remains unchanged. No active host installation is modified by this publication.
