saminn-background-check

Use before any git commit in saminn-background-check. Defines subject-line scope tags, body detail requirements, staging discipline, and PR-vs-direct-commit guidance.

Use when starting or ending a work session in saminn-background-check, after finishing a phase or a source/subsystem branch, or whenever the project's current phase, branch, or next step changes — so docs/plan/ never goes stale.
