STATE-WP-0092-T01: flavor is a closed bucket on workplans and tasks;
residuals are a flavor, not a kind, and are omitted from default open
views until demand or risk promotes them. depends_on is the workplan
frontmatter edge.
Allow version-controlled agent rule files under .claude/rules/ while keeping
machine-local Claude Code state ignored. Aligns with state-hub gitignore pattern.
