MessageCard

Adaptive, collapsible cards — newest expanded, older messages collapsed to a one-line preview. Long/HTML content renders full-width in a sandboxed iframe; quoted-reply chains hide behind a toggle. Your own messages get a subtle accent tint (not a right-aligned bubble).

Field notes — week 24 A quick roundup of what shipped, what didn't, and where the interesting friction was this week. Numbers first, prose second. - Ingest: two-step retrieval is live in staging. Duplicate webhooks are a no-op. - Notifications: receipts cron is catching <1% token drift/day. - Rules: 3 users hit the "5 rules" cap; considering unlimited with paging. The most interesting bug was a race between the ingest worker and the notify worker where a message could be visible on the thread before its push landed — fixed by enqueueing notify from inside the ingest transaction boundary, not before. "The push should never beat the row." — from the postmortem. Next week: swipe-action metrics, and a first pass at the compose screen's attachment picker.
