The pipe-separated 6-field format — ID, category, title, summary, date, and tags — is the unsung hero of 5,000+ article production. Its simplicity enables rapid generation with no markup or nesting, its strictness prevents structural errors (exactly 6 fields, no ambiguity), and its searchability enables programmatic analysis via grep, sort, and count operations. The format is deliberately minimal — trading expressive range for production speed and structural reliability.
