Spec Matrix
Instructions
- Maintain
MATRIX/CHANNEL_MATRIX.md(human-readable 2026 spec table) andMATRIX/PRODUCTION_GRID.csv(machine-readable rows). - Each grid row: channel, placement, width, height, aspect_ratio, max_file_size, format, notes.
- Validate assets against rows (exact pixels, ratio, size, format) — see
20-spec-validation. - Always append: "verify against official platform docs before production."
Examples
- "Add TikTok in-feed 1080x1920 to the grid" → new CSV row + matrix note.
Performance Notes
- Keep CSV the source of truth for automation; the markdown table is documentation.
Troubleshooting
- Spec uncertainty → mark
verifyrather than guessing pixel values.
