# Deploying the GraphTestbed scoring server to HF Spaces

All commands assume `HF_TOKEN` is exported and has **write** scope on the
`lanczos` namespace.

## 1. Seed the GT dataset repo

```bash
HF_TOKEN=$HF_TOKEN python server/space/push_gt.py \
    --repo lanczos/graphtestbed-gt \
    --gt-dir ~/graphtestbed-gt
```

This creates the **private** dataset repo if it doesn't exist and uploads
each `<task>.csv` to `gt/<task>.csv`. Verify at:

  <https://huggingface.co/datasets/lanczos/graphtestbed-gt>

## 2. Create the Space

```bash
huggingface-cli repo create graphtestbed --type space --space_sdk docker
```

Or in the web UI: New Space → name `graphtestbed` → SDK: **Docker**.

## 3. Set the Space secret

In Space Settings → Variables and secrets, add:

| name | value |
| --- | --- |
| `HF_TOKEN` | same token (write scope on `lanczos/graphtestbed-gt`) |

Optional overrides (set as **variables**, not secrets):

| name | default | when to override |
| --- | --- | --- |
| `GT_DATASET_REPO` | `lanczos/graphtestbed-gt` | running multiple Spaces against different GT |
| `GT_BACKUP_INTERVAL` | `60` | tighter durability vs. fewer commits |
| `GT_QUOTA` | `5` | bumping during a benchmark sprint |

## 4. Push the code to the Space

```bash
# One-time
git remote add space https://huggingface.co/spaces/lanczos/graphtestbed

# Each deploy (HF prompts for credentials: user=lanczos, password=$HF_TOKEN)
./server/space/push_to_space.sh
```

The script overlays `server/space/README.md` at repo root on a temp branch
and force-pushes to `space/main` (HF reads its frontmatter from root
README). Your GitHub root README is untouched.

First build ~3 min (pandas + sklearn wheels). Subsequent ~30 s.

## 5. Smoke-test

```bash
curl -s https://lanczos-graphtestbed.hf.space/healthz | jq
```

Expect:
```json
{
  "status": "ok",
  "tasks": ["arxiv-citation", "figraph", "ibm-aml", "ieee-fraud-detection"],
  "gt_present": ["figraph", "..."],
  "quota_per_day": 5,
  "uptime_unix": 1776633751
}
```

If `gt_present` is empty, the boot bootstrap couldn't read from the dataset
repo — check the Space logs and verify `HF_TOKEN` has read scope on
`GT_DATASET_REPO`.

## 6. Hand out the URL

```
export GRAPHTESTBED_API=https://lanczos-graphtestbed.hf.space
gtb submit figraph --file preds.csv --agent my-agent-v1
```

## Reading the leaderboard back as a maintainer

```bash
huggingface-cli download lanczos/graphtestbed-gt \
    leaderboard.db \
    --repo-type dataset \
    --local-dir ./backup

sqlite3 backup/leaderboard.db \
    "SELECT task, agent, primary_metric, n_rows, submitted_at
     FROM submissions ORDER BY submitted_at DESC LIMIT 20"
```

The full per-submission CSV archive lives under `submissions/<task>/<agent>-<run_id>.csv`
in the same dataset repo.
