Swept every Route_*_p<n><kind> in every stage table, resolving each squadron to its unit via that stage's own UnitGroup, with F/S/M routes as the control: A/B routes : 23 of 67 resolved are attacker/bomber = 34.3% F/S/M control: 27 of 928 = 2.9% A ~12x enrichment, so the signal is real and not a one-stage accident. But "A means the marked attackers" remains too strong: of the 67 resolved A/B routes, 35 carry UN_mn040_Asteroid_Big and 9 carry UN_n001_TTRL_Box (TTRL = tutorial). A reading covering all four is "things the mission wants shot" -- attackers in a combat stage, asteroids in an asteroid stage, boxes in a tutorial -- which keeps A as an objective marker rather than a unit-class marker, but that is a reading of four unit types, not a measurement. Records a near-miss: a truncated listing showed the first ~26 rows, dominated by early stages, in which every resolved row was an attacker. I nearly wrote "23/23, unanimous". The full set is 23/67 -- the tail of a sorted listing is not the distribution. The Stage 02 derivation is unaffected: its three A routes are still exactly the three n=4 attacker squadrons.
