The 9am scan — every L1 SHOULD-constraint violation across all 5 invariant views (drift, ledger drift, overdraft, limit breach, expected EOD balance), scoped to the most recent business day in the data. Replaces v5's ar_unified_exceptions matview with a live UNION; no REFRESH contract. KPI tracks total open count; bar chart breaks down by check_type; detail table sorts by magnitude so the biggest variances surface first.
Open Exceptions
Total count of L1 SHOULD-constraint violations on today's business day across all 5 invariant checks.
Exceptions by Check Type
How today's open exceptions distribute across the 5 L1 invariants. Spikes in one check kind point at a recurring error class to investigate first.
Exception Detail
Every violation on today's business day. Sorted by magnitude (largest first) so the biggest variances are the top rows. Left-click an account_id to narrow Drift to that account; right-click → View Daily Statement to open the per-account-day walk.
Institution Context Generic SPEC-shaped instance for cleanliness testing of the lifted common.l2.seed primitives.
**About this sheet**
Today's Exceptions aggregates every L1 SHOULD-constraint violation that landed on the most recent business day. One row per violation, across all kinds -- drift, overdraft, limit breach, expected EOD balance breach, pending aging, unbundled aging.
Drill from a row to the source sheet for that kind to see the formal SHOULD-constraint, the full column shape, and the remediation guidance specific to that violation:
- **Drift** -- internal sub-ledger doesn't match the bank's cumulative net. - **Overdraft** -- internal account went negative. - **Limit Breach** -- outbound flow exceeded the rail's cap. - **Pending Aging** -- transaction stuck in Pending past its rail's max. - **Unbundled Aging** -- posted leg not bundled into an AggregatingRail past the cap. - **Expected EOD Balance Breach** -- an account day declared an expected EOD balance the stored balance didn't match.
