### 4. Application Supervision
#### Update the application supervisor
```elixir
# lib/islab_db/application.ex
defmodule IsLabDB.Application do
@moduledoc false
use Application
@impl true
def start(_type, _args) do
children = [
{IsLabDB, []}
]
opts = [strategy: :one_for_one, name: IsLabDB.Supervisor]
Supervisor.start_link(children, opts)
end
end
```
### 5. Basic Tests
#### Create foundational tests
```elixir
# test/islab_db_test.exs
defmodule IsLabDBTest do
use ExUnit.Case
doctest IsLabDB
setup do
# Clean up any existing universe state
cleanup_test_universe()
# Start fresh universe for each test

assert {:ok, :stored, shard, operation_time} = IsLabDB.cosmic_put("test:key1", %{data: "value1"})
assert is_atom(shard)
assert is_integer(operation_time)
assert operation_time > 0
end

cosmic_constants: constants
} = metrics

end
test "filesystem persistence creates cosmic structure" do
# Store some data

# Give async persistence time to complete
:timer.sleep(100)
# Check that filesystem structure exists

# Check data was persisted

## 🏃‍♂️ Running Phase 1
### Start the Universe
```bash
# Get dependencies
mix deps.get
# Run tests
mix test
# Start interactive session
iex -S mix
# In IEx:

IsLabDB.cosmic_get("user:alice")
IsLabDB.cosmic_metrics()
```
### Explore the Cosmic Filesystem
```bash
# View the cosmic structure
tree /data
# Read the universe manifest
cat /data/universe.manifest | jq
# Explore a data record
cat /data/spacetime/hot_data/particles/user/user_alice.json | jq
# Check directory manifests
cat /data/spacetime/hot_data/particles/_manifest.json | jq
```
