Posted transactions whose bundle_id is still NULL past their rail's max_unbundled_age cap. An AggregatingRail's job is to pick up these legs and group them into a Bundle; an unbundled leg older than the rail's cadence means the bundler hasn't fired or is failing to match. KPI shows total stuck count; the aging bar chart breaks the population into 4 buckets (<1d, 1–2d, 2–7d, >7d) — the typical max_unbundled_age cadence is a day or two, so buckets are wider than Pending Aging's. Right-click any row → View Transactions to see every leg of that transfer.
Count of Posted transactions whose bundle_id is still NULL past their rail's max_unbundled_age cap. Healthy = 0. Demo-seed note: the bundled demo plants stuck-unbundled rows so this view has something to show — expect a non-zero count on demo deploys.
Sum of amount across the stuck-unbundled legs. The dollar side of the reconciliation gap — how much money is sitting unrolled-up past its rail's bundling cap.
Distribution of stuck-Unbundled transactions across 4 age bands, stacked by rail. Right-skewed (>2d, >7d) ⇒ the bundler hasn't fired for those rails in a while. Color bands surface per-variant rollup for XOR-grouped multi-mode templates.
Every stuck-Unbundled leg with rail / amount / posting / live age. max_unbundled_age_seconds is the rail's cap (inlined at view-emit time from L2). Right-click any row → View Transactions to see every leg of that transfer.
