+        # Why `increase()` and not `sum(counter)`:
+        #   Prometheus counters are per-process by design — they reset to
+        #   zero on every pod restart (rollout, OOM, eviction, node
+        #   reschedule). A naive `sum by (...) (counter)` query therefore
+        #   drops to zero whenever the verifier restarts, producing a
+        #   misleading "0 requests" reading on offers with real on-chain
+        #   traffic. `increase()` performs reset detection at query time
+        #   across the samples the TSDB holds, accounting for the wraps.
+        #
+        # Why `[7d]` and not `[8d]` (matching retention):
+        #   The TSDB is the canonical persistence layer. `increase()`
+        #   needs samples on both sides of the window edge to do reset
+        #   detection at the left edge; a 7d window inside 8d retention
+        #   gives a 1-day headroom so the rule keeps working at exactly
+        #   the moment data ages out, instead of silently producing
+        #   NaN/undercounts at the boundary.
