- ipng_stats_logtail now accepts an optional if=$variable parameter that suppresses log lines when the variable is empty or "0", following the same semantics as nginx's access_log if=. The condition is checked before format rendering for zero overhead on filtered requests. Filtered requests are still counted by stats. - Log format examples updated to include $scheme for http/https visibility, and renamed to ipng_stats_logtail to match production. - Robot test added for the if= filter (19 tests, 19 pass). - FR-8.5 added to design doc for the if= semantics.
