First 10 bars proved the env_step kernel produces actual_dir=Long for
Long picks correctly at cold start. So the gate that turns 100% of
Long/Short picks into actual_dir=Flat in val_dir_dist must activate
LATER in the window — likely past the first chunk boundary.
Extended sampling: first 10 bars, every 100 bars to 1000, every 1000
bars to 10000, every 10000 bars throughout. Also adds a "mismatch"
trigger that fires when picked dir is Long/Short but actual_dir is
not — every 137 bars to keep printf volume bounded. cash field added
to spot capital drain or anomalous accumulation.
