Notifications
Notifications surface in two places — the in-app feed (the bell in the right sidebar) and the per-category settings page (Settings → Notifications).
In-app notifications
Open the bell from the right sidebar:

Notifications group by recency — Last 7 Days, then Earlier with absolute dates. Each row shows the title, a one-line description, time, and an unread dot.
There is no type-filter inside the panel — the only top-right controls are Mark all as read and the gear (jumps to settings). The list caps at 100 items.
Settings: per-category opt-out, method, and digest
Open Settings → Notifications:

- Method — In-app only, Email only, or Both. Picking In-app hides the digest selector but doesn't wipe the saved cadence — switch back to Email and your old digest setting returns.
- Category tabs — Rules, Issues, Rebates, Deductions, Cases, Tasks, System. Each tab carries the per-category toggles, plus thresholds where relevant (e.g. amount over $X, deadline within Y days).
Transactional emails fire independently of the digest cadence — a "Both + Daily" user gets per-event emails and a daily digest. Comparison operators differ across categories: deadline-based notifications fire on ≤, amount-based ones fire on strict >.
System event alerts
The System tab covers infrastructure events — sync failures, rule evaluation completion, pipeline pauses. These fire from the cron and the import pipeline rather than from operator activity. Most are deduplicated so a recurring failure doesn't spam the feed; sync failures are the one exception, where each occurrence creates a new entry.
