Lyrics:
Verse 1
I trace the lines on a bright-screen night,
Silent arrows in a web of might.
Traits talk softly, tangled and wide,
I’m looking for the cause inside.

Pre-Chorus
Not one story, not one thread,
Some paths live, some paths mislead.
Hold the noise, let the signal spark,
Draw the edges in the dark.

Chorus
Follow the edges, let the numbers sing,
Separate the shadow from the string.
Direct or drifting through a middle flame,
We name the cause, we name the change.

Verse 2
A cloudy link can dress as fate,
When side-roads crowd the causal gate.
But with a graph and a careful aim,
False bright answers lose their claim.

Bridge
If a habit bends the mind in time,
Or learning lifts what fear can bind,
Cut the chain where it starts to pull,
One small shift can move it all.

Final Chorus
Follow the edges, let the numbers sing,
Find what leads and what it brings.
Past the pleiotropic masquerade,
We keep the truths the data saved.
