## Use lifecycleLedger

A complete small caller. Values are illustrative; check the returned result and package requirements before connecting live resources.

Verification: type checked

```yh
using diagnostics

// Describe failures, collect runtime traces, and make execution observable.
lifecycleLedger sample = lifecycleLedger("Nova")
Console.Log(Text.From(sample.name))

```

Save this beside start.yh as project.mech:

```toml
manifestVersion = "2"
package = "api.example.diagnostics__lifecycleledger"
version = "0.1.0"
languageEdition = "yeho-core-2026.1"

[app]
kind = "headless"

[[dependencies]]
package = "console"
version = "0.1.0"
path = "../../../yeho/packages/console"

[[dependencies]]
package = "diagnostics"
version = "0.1.0"
path = "../../../yeho/packages/diagnostics"

```

Extract the example archive beside the yeho and dolphin checkouts. This example requires those source dependencies and a current developer compiler.

Package presence and a declaration do not establish support on every host. Host services need their platform and lifecycle setup.
