$ca-adr — author an ADR

Record an architectural decision as a numbered, dated ADR. Title the decision clearly — name what was decided, not what was considered (`"Use PostgreSQL as the primary database"`, not `"Database selection"`). This is the only sanctioned path to author an ADR.

Routes to

The `decision-lifecycle` skill ([routines/decision-lifecycle/SKILL.md](../../routines/decision-lifecycle/SKILL.md)). The skill owns numbering, the file template, the `proposed → accepted → superseded | rejected` status lifecycle, and writes the file to `<project-root>/.codearbiter/decisions/`. Status transitions require explicit user instruction; the orchestrator never advances an ADR on its own.

When NOT to use

• Check the health of existing ADRs → `$ca-adr-status`.
• Reconcile or challenge a suspect ADR → `$ca-reconcile`.
• Ask about a decision without recording it → `$ca-btw`.

Hard gate

An ADR is authored ONLY via `$ca-adr` with explicit user attribution. MUST NOT author an ADR as the disposition of a routine finding — decision-worthy findings surface to the user or to `open-questions.md` as a `[CONFIRM-NN]`. MUST NOT resolve a `[CONFIRM-NN]` in the ADR by guessing.
