I am helping my friend who works in a video game store, we need to confirm whether the client who bought a game on the same day that the fighter tomas villa passed away did join our member program. We also need the name and genre of the game that they bought, based on our database.

# Virtual Filesystem
You work in a terminal over a virtual filesystem. Read files with shell
commands.
Command output comes back whole, however long. Some files here are large,
so point `grep -r`, `rg`, `find` and `cat` at the directory or file you
need rather than at a whole mount.
| path | what it is |
|---|---|
| `/mongodb` | Your MongoDB databases, read-only; change them with the `mongodb` CLI. |
| `/tmp` | Scratch space, in memory. |
## `/mongodb`
```
/mongodb/
<database>/
database.json
collections/
<collection>/
schema.json
documents.jsonl
views/
<view>/
schema.json
documents.jsonl
```
- `database.json`: `{database: str, collections: list[{name: str}],
views: list[{name: str}]}`
- `schema.json`: `{database: str, name: str, kind: str, validator: dict |
null, fields: list[{path: str, presence: number, types: dict}],
primary_key: str, indexes: list[{name: str, keys: dict, type: str}],
sampled: int}`, read from a sample of `sampled` documents
- `documents.jsonl`: one document per line, in MongoDB Extended JSON: a date
reads as `{"$date": "..."}`| name | workspace-filesystem |

# Available commands
Python (`python` or `python3`), Perl, JavaScript/Node.js, and TypeScript
runtimes are unavailable. Use the shell commands and task CLIs documented
below; do not probe for or attempt to install other runtimes.
Standard Unix commands, among them:
cat head tail ls find grep wc sort uniq cut tr sed awk
diff tee xargs jq
with pipes, `>` redirection and `$(...)` substitution.
Do not probe the machine with `which`, `type`, `--version`, `env`, `ps`,
`echo $PATH`, `ls /usr/bin` or `cat /usr/bin/<command>`: they tell you
nothing about the task.
A filename with a space in it needs quoting, as it would in any shell.
## mongodb
Use `mongodb <command> '<JSON arguments>'`. Run `mongodb <command> --help`
to get more information.
```sh
mongodb list-collections '{"database":"DATABASE"}'
