Timeless Phoenix

One dep, one child_spec, one router macro — you get:

Metrics — TimelessMetrics stores telemetry metrics that survive restarts
Logs — TimelessLogs captures and indexes Elixir Logger output
Traces — TimelessTraces stores OpenTelemetry spans
Dashboard — All three as LiveDashboard pages, plus built-in charts with history 

With Igniter (recommended)

Add the dependency to mix.exs:

,

Then run:

mix deps.get mix igniter.install timeless_phoenix

This automatically:

Adds {TimelessPhoenix, ...} to your supervision tree
Configures OpenTelemetry to export spans to TimelessTraces
Adds import TimelessPhoenix.Router to your Phoenix router
Adds timeless_phoenix_dashboard "/dashboard" to your browser scope
Removes the default live_dashboard route (avoids live_session conflict)
Updates .formatter.exs
