+`welcomebot-signups` (also `/usr/local/bin/welcomebot-signups`, source
+`bin/welcomebot-signups`) reads the persistent `signup_ip` sqlite table
+directly — a permanent record of every classification decision, independent
+of log retention:
+
+```bash
+ssh admin.yttrx.com welcomebot-signups              # last 20 decisions
+ssh admin.yttrx.com welcomebot-signups --flagged    # only datacenter-flagged signups

+Usage: welcomebot-signups [options]
+
+Print signup-IP classification records (acct, ip, org, classification,
+flagged, ip_block status, timestamp) from the welcomebot's persistent
+sqlite store, newest first.
+
+Options:
+  -n, --limit N     Show the last N rows (default: $limit; 'all' for everything).
+      --flagged     Only flagged (datacenter) signups.
+  -a, --acct ACCT   Only rows for this acct (exact match).
+  -h, --help        Show this help.
+
+Examples:
+  welcomebot-signups                  # last $limit classification decisions
+  welcomebot-signups --flagged        # only datacenter-flagged signups
+  welcomebot-signups -n all
