7 Gate Blink All-in

Detected if Twilight Council is the FIRST tech building (before Robo AND Stargate), Blink is researched by 9:00, 6+ Gateways exist by 9:00, the 5th Gateway was STARTED before the 3rd Nexus was STARTED, AND no 3rd Nexus was STARTED before 6:00 -- a heavy Twilight-first multi-Gate Blink all-in. The Twilight-first guard keeps Robo-first openers with 6+ Gateways + late Blink off this label (those fall through to Robo First). "Taken" the 3rd Nexus means construction was initiated, not finished: a player can drop a LATE 3rd Nexus (6:00 or later) and add Gateways while it is still building and those Gateways are still macro reinforcement, not all-in production. The build is excluded if the 3rd Nexus broke ground before the 5th Gateway, OR if any 3rd Nexus was taken before 6:00 (a fast 3rd Nexus is a macro commitment, so those builds fall through to the 3/4 Gate Blink (Macro) labels). A DT Drop opener that later macros into a multi-Gate Blink composition is also excluded -- the DT Drop signature is checked first.
