# Alpha Robustness Matrix for Kaggle Offline

This path is intentionally separate from the stable backtest flow.

Use these files:

- `/Users/giaphu/Documents/Pylab/AAE-new/deploy/v2/jsonl_alpha_robustness.py`
- `/Users/giaphu/Documents/Pylab/AAE-new/deploy/v2/run_alpha_robustness_matrix.py`
- `/Users/giaphu/Documents/Pylab/AAE-new/backtest/robust_factor_executor.py`
- `/Users/giaphu/Documents/Pylab/AAE-new/backtest/robust_qlib_backtester.py`

The top-10 alpha pack prepared from `test7` is bundled here:

- `/Users/giaphu/Documents/Pylab/AAE-new/data/robustness_inputs/test7_top10_best_return_alpha_pack.jsonl`

## What the standard matrix runs

The standard matrix avoids duplicate cases where the baseline already covers the anchor setting.

Cases included:

- `baseline_replay`
- `topk_10`
- `topk_15`
- `weight_alpha_score_cap20`
- `weight_alpha_score_no_cap`
- `fee_0bps`
- `fee_10bps`
- `fee_20bps`
- `fee_30bps`
- `fee_50bps`
- `rebalance_10d`
- `rebalance_20d`
- `score_rank`
- `score_zscore`
- `score_rank_zscore`
- `frozen_recent_2026_ytd`

The baseline is:

- `backtest_engine = custom`
- `top_k = 5`
- `rebalance_freq = 5`
- `custom_weight_mode = equal`
- `max_pos_each_stock = 0.2`
- `buy_fee = sell_fee = 0.0013`
- `enforce_cash_limit = True`
- `volume/amount limits = off`

## Kaggle offline notebook cells

### 1. Install offline runtime

```python
import sys
import subprocess
from pathlib import Path

REPO = Path("/kaggle/input/datasets/gplebih/aae-new")

subprocess.run(
    [sys.executable, str(REPO / "deploy" / "v2" / "install_kaggle_offline.py")],
    check=True,
)
```

### 2. Run the full standard matrix on the bundled top-10 alpha pack

```python
import sys
import subprocess
from pathlib import Path

REPO = Path("/kaggle/input/datasets/gplebih/aae-new")
INPUT_JSONL = REPO / "data" / "robustness_inputs" / "test7_top10_best_return_alpha_pack.jsonl"
DATA_PATH = REPO / "backtest" / "data" / "daily_pv.h5"
OUTPUT_ROOT = Path("/kaggle/working/alpha_robustness/test7_top10_standard_matrix")

cmd = [
    sys.executable,
    str(REPO / "deploy" / "v2" / "run_alpha_robustness_matrix.py"),
    "--jsonl", str(INPUT_JSONL),
    "--data-path", str(DATA_PATH),
    "--period", "test",
    "--backtest-workers", "4",
    "--capture-detail-artifacts",
    "--output-root", str(OUTPUT_ROOT),
]

subprocess.run(cmd, check=True)

print("OUTPUT_ROOT =", OUTPUT_ROOT)
```

### 3. Debug on only a few cases first

```python
import sys
import subprocess
from pathlib import Path

REPO = Path("/kaggle/input/datasets/gplebih/aae-new")
INPUT_JSONL = REPO / "data" / "robustness_inputs" / "test7_top10_best_return_alpha_pack.jsonl"
DATA_PATH = REPO / "backtest" / "data" / "daily_pv.h5"
OUTPUT_ROOT = Path("/kaggle/working/alpha_robustness/test7_top10_smoke")

cmd = [
    sys.executable,
    str(REPO / "deploy" / "v2" / "run_alpha_robustness_matrix.py"),
    "--jsonl", str(INPUT_JSONL),
    "--data-path", str(DATA_PATH),
    "--period", "test",
    "--backtest-workers", "2",
    "--case-filter", "baseline_replay,topk_10,weight_alpha_score_cap20",
    "--capture-detail-artifacts",
    "--output-root", str(OUTPUT_ROOT),
]

subprocess.run(cmd, check=True)
```

## What comes out

Each case gets its own folder under:

- `OUTPUT_ROOT / cases / <case_id>`

The matrix runner also writes merged files at the root:

- `matrix_cases.csv`
- `merged_summary.csv`
- `merged_trials.csv`
- `merged_summary_yearly.csv`
- `merged_trials_yearly.csv`
- `merged_aggregate_yearly.csv`
- `coverage_sparsity_summary.csv`
- `matrix_manifest.json`

## Coverage / sparsity summary

`coverage_sparsity_summary.csv` is derived from detail artifacts and includes metrics like:

- number of rebalance days
- number of trade days
- mean / median / min / max target count
- percent of rebalance days with fewer names than `top_k`
- cash-weight stats
- top-k signal count by day
- all-zero-score day rate

This means `coverage / sparsity robustness` is analyzed from artifact outputs, not by running a separate backtest axis.
