ATM read/query benchmark

AV.4 additive read benchmark families

Generated: 2026-09-04T06:54:46.399585Z

PASS

Read/query campaign 20260904T065446Z-rand-m5.local-read on rand-m5.local.

Corpus seed av4-corpus-v1; generator av4-corpus-generator-1; fan-out 32.

Measurement note: Throughput floors are end-to-end CLI (spawn-dominated) sensors; deeper lane-sensitivity redesign is deferred under AV-EXP-C6.

D5 implementation status

Reader-lane runtime gauges are explicitly marked unimplemented until the AV.1b reader cutover publishes them. Null values are not zero measurements.
