The splits completeness floor is TIME-based (trust hours complete since shipper
connect) and blind to event-loss-by-rotation (2026-07-10: raw_events rotated
every 1-2min, cruncher lost ~85% of us-32 events, floor still called the hours
complete). Shipper now injects {"__shipstat__":1,"sess":..,"sent":N,"ts":..}
every 1000 lines or 30s through the SAME tcp pipe. Cruncher diffs shipper-sent
vs DB-ingested per gateway/hour -> a reconciliation-based floor that catches the
loss a clock cannot. sess=connection-start epoch so resets on reconnect are
detectable. Logic in a mounted .awk file (not inline) to dodge sh/awk quoting.
Verified on busybox:1.36 (systime/fflush OK). NOT deployed until claude@'s
cruncher filters __shipstat__ from event parsing - coordinating via SIP.
