Subject: [PATCH] fix: bgp.he.net name+country fallback for unregistered ASNs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

For ASNs with no PeeringDB entry and no RIPE Stat holder (e.g. reserved
or unannounced ASNs), extract name from bgp.he.net page title and
country code from the /country/XX href. Eliminates the last 2 CRITICAL
audit failures (AS34465 → 'RIPE NCC ASN block'/GB, AS59947 → 'LLHOST
INC. SRL'/RO). Audit result: 80/82 PERFECT, 0 CRITICAL. v0.6.8.

+
+### Fixed
+- **Name fallback via bgp.he.net title**: ASNs without a PeeringDB entry and no RIPE Stat holder
+  now extract their name from bgp.he.net page title (e.g. LLHOST INC. SRL, RIPE NCC ASN block)
+- **Country code fallback via bgp.he.net**: ASNs with no country in rir-stats-country
+  now derive their 2-letter country code from bgp.he.net href (e.g. /country/RO, /country/GB)
+- Zero CRITICAL data errors across 82 of 103 audited ASNs (21 large Tier-1 ASNs exceed 15s cold-cache)
