Nobody can say for certain what breaks if this one column gets renamed.
What you'll have at the end
A lineage map for one field showing every table, job, and dashboard between the raw event and the number on screen
You need
A transformation project where the field's origin table and every model between it and the reporting layer live in version-controlled queries, plus enough access to run that project's own build and documentation commands and to query the warehouse's own record of executed statements.
Not covered
Deciding whether the proposed rename is worth doing in the first place. That conversation belongs to whoever owns the field, not to the map you build here.
Leans on
Trace a wrong dashboard number back to its real cause
when a number is already wrong today and you need to find the one break that caused it, not map every risk before anything happens
Draft a data contract that survives a schema change
once the map names who depends on the field, and you want their commitment written down instead of rediscovered next time
