format.md listed `wiki:` among the domain fields, between depends and origin, and issue.py had never heard of it. The field fell into extra and rendered with the foreign keys — sorted in after the sync fields, which the same document forbids one line below the table. Written without brackets it parsed as a single string, and nothing but a text editor could set it. Implemented rather than de-documented: page_ls.py --titles already prints these titles, so the field was designed and only unwired. DOMAIN_KEYS and LIST_KEYS learn it, Issue carries it, and issue_new.py gets a repeatable --wiki flag. Titles only, as the format says: no path, no sub_url, no lookup. The tracker has no field for it, so it is never sent and a pull does not bring it back — format.md now says so. Closes #32 Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
