zig build test was 9m13s, and the tests it actually ran were a small fraction of that: it also compiled the e2e and smoke harnesses in the pinned ReleaseSafe and then never executed them. test is now unit tests only -- 2m54s cold, 1m42s warm -- and the new gate step carries those two compile proofs.

The dst, bench and smoke UNIT tests deliberately stay on test. They are unit tests despite their siblings' names, zig build dst/smoke run the simulation and the interop check rather than them, and CI invokes the lanes one by one and never invokes gate -- so moving them would have dropped them from CI while every step still looked green. ci_test's declared_steps records gate as intentionally not-in-CI, and names that failure mode for the next lane someone adds. check-in: 7363238ad5 user: dmestas tags: trunk
