CMF Buds 2: Hey everyone, I need some expert advice on curing/solving the cut side

A double-sided flex cable has torn right at the edge, immediately next to a small SMD capacitor. This section is supposed to connect the mainboard to the battery side. Because the tear happened right at the edge, the original soldering pads on the flex are completely ruined/missing.

The Goal: > I want to safely find the correct paths to run jumper wires from the remaining components/board to the battery terminals.

My Questions:

Since the flex is double-sided and the edge is ruined, what is the correct step-by-step method to use a multimeter (Continuity, Resistance, or Diode mode) to accurately identify which side of this SMD capacitor connects to Ground (GND) and which side connects to the positive line?

How can I verify that my new jumper connections are 100% safe and correct before I actually connect the lithium battery, to prevent blowing up the charging IC or causing a short?

What I've done so far was connecting the FPC to the main board, and by using a multimeter I've found that the red side of the capacitor goes to ground.
