 ## Use the glossary's vocabulary
 
-When your output names a domain concept (in an issue title, a proposal, a hypothesis, a test name),

-write `mark` and not `logo`, `colourway` and not `colorway`, `inner symbol` and not `glyph`.

-the project doesn't use (reconsider) or there's a real gap (note it for `/domain-modeling`).

 When set to `yes`, PRs run through the same labels and states as issues, using the `gh pr` equivalents:
 
 - **Read a PR**: `gh pr view <number> --comments` and `gh pr diff <number>` for the diff.
-- **List external PRs for triage**: `gh pr list --json` has no `authorAssociation` field, so the association has to come from the REST API, where it is `author_association` (snake_case):
-  ```
-  gh api "repos/{owner}/{repo}/pulls?state=open&per_page=100" \
-    --jq '.[] | select(.author_association | IN("CONTRIBUTOR","FIRST_TIME_CONTRIBUTOR","NONE")) | {number, title, author: .user.login}'
-  ```
-  That keeps only external authors; `OWNER`, `MEMBER` and `COLLABORATOR` are dropped. `gh api` substitutes `{owner}`/`{repo}` from the current clone.
+- **List external PRs for triage**: `gh pr list --state open --json number,title,body,labels,author,authorAssociation,comments` then keep only `authorAssociation` of `CONTRIBUTOR`, `FIRST_TIME_CONTRIBUTOR`, or `NONE` (drop `OWNER`/`MEMBER`/`COLLABORATOR`).
 - **Comment / label / close**: `gh pr comment`, `gh pr edit --add-label`/`--remove-label`, `gh pr close`.
 
 GitHub shares one number space across issues and PRs, so a bare `#42` may be either: resolve with `gh pr view 42` and fall back to `gh issue view 42`.
