History
Max 2187a5d752 training/models: KNN as a registered supervised model 
Non-parametric baseline alongside GBT/MLP/CNN/GRU/LSTM/Transformer.
Same BaseModel + schema-hashed checkpoint contract; sidecar is a
pickled sklearn KNeighborsClassifier (.knn.pkl) handled by the
existing checkpoint machinery alongside .xgb.json / .pt.

KNN's storage cost = n_train_rows × n_kept_features × 4 bytes.
At 660k windows × 145 kept (realistic mode) features = ~380 MB
sidecar; at 230 features (oracle) = ~600 MB. Heavy but ships through
the same artifact-upload path.

trainer/run.py learns a third fit branch:
  - GBT — XGBoost early stopping on val mlogloss
  - KNN — fit() memorizes; "training time" is val/test predict cost
  - NN  — train_nn loop (the rest)

Manifest gains knn-realistic + knn-oracle at priority 95 (just
below GBT). KNN's k=10 default lives in the model class — overriding
via hyper.k requires adding --k to run.py first to avoid the
unknown-arg exit-2 issue.

Smoke verified on the 567-episode subset:
  knn   oracle    val=0.7365  test=0.1333  (held-out k-gamingcom)

That val/test gap (0.74 → 0.13) is the cross-device generalization
story: KNN memorizes elliott-thinkpad's local feature space and
falls apart on the other host. Honest baseline for the comparison
report.
