Authoring rules

• One decision per file, MADR template (NNNN-<kebab-slug>.md).
• Sequential numbering, zero-padded to 4 digits, never reuse.
• Status values: Proposed · Accepted · Deprecated · Superseded by NNNN.
• Date = decision date (not created date).
• Cross-service decisions go in developer/decisions/, not here.
