# Existing Tags

This file is a reference for writing articles.
**Before choosing tags, read this list and reuse existing tags whenever they fit.**
Coin a new tag only when no existing one covers the article's main domain.
When a new tag is coined and accepted, add it here with a description.

## How to use this file

1. At the end of Phase 2, propose 2–4 tags for the article.
2. For each tag, state whether it is **reused** (from this list) or **new** (coined now), and one-line justification.
3. If you coin a new tag, flag it explicitly so the user can confirm and add it here.
4. Never use more than 4 tags. Prefer fewer, broader tags over many specific ones.

# Existing Series

This file is a reference for writing series articles.
**If the user asks for a series article, check this list first.**
Use the exact series name as listed — casing matters (it becomes a URL slug).
If it's a new series, coin a clear name, note it as new, and let the user confirm before writing.

## How to use this file

- If the user says "this belongs to an existing series", match the name exactly from this list.
- If the user proposes a new series name, flag it as new and confirm before using it in frontmatter.
- `series` and `part` must both be present in frontmatter when used; omit both if the article is standalone.
