Practical notes

[gotcha] Circular IDs are case-sensitive and the issuer’s exact punctuation matters when looking them up on the official site.
[industry practice] Most ops teams subscribe to the issuer’s email distribution list rather than scraping the site — leads to more reliable real-time tracking.
[risk trade-off] Some entries are marked [unknown — verify] where the agent could not re-fetch the primary URL or the document used informal numbering; treat those as leads, not citations.
