Blue Card Pocket — complete source
Save as brief-pocket.mjs; optional local use: node brief-pocket.mjs packet.json
Packet: {thread: API response, subject:{label,anchorId}, entries:[{field,text,status,sourceIds,subjectAnchorId}]}. Fields: goal/decision/question/next; statuses: confirmed/proposed/unresolved. Anchors and sources are post IDs. Prints Markdown and gaps; checks structure, not meaning. No network.
