Meaning
Cache invalidation makes a previously stored response or artifact ineligible for reuse when its identity or validity changes.
A practical example
Updating a subtitle revision may require a new rendered output key while leaving a prior accepted package intact.
What to check
Deleting every cache is not the only strategy. Use clear version identities and distinguish public page caching from private project artifact reuse.
