Upgrading from 0.4.x

If you installed older personal Layer-1 ethos files, archive rather than delete ~/.claude/engineering-ethos.md and the Foreman skill overrides under ~/.claude/skills/. Remove or update any ~/.claude/CLAUDE.md pointers to those files, then use the bundled ethos tool.

User overrides take precedence over bundled skills, so a stale override can silently shadow the current protocol. See skill override precedence.
