## For engineers

Data is stored as **tar shards** (the hub caps a directory at 10,000 files and these tiers
run to millions). Members keep their original names and relative paths.

```python
import tarfile
with tarfile.open("0000.tar") as tf:
    print(tf.getnames()[:5])
    tf.extractall("out/")
```

Every shard records its **sha256** in the pipeline ledgers; shards are append-only, so a
resumed run re-uploads only what changed. A shard with a failed member is never marked
complete, so missed files are retried rather than dropped.
