Shredding a person
The schema marks personal fields. Each is designed to be encrypted with one key per person per space. To shred a person, a member performs a work order and a second account gives its sign-off; then the key is destroyed. A person’s data can be shredded this way, and the audit trail of who changed what is designed to survive it.
What it does not reach: devices that never come back online, a modified client that ignores the shred, a relay backup from before the shred that a member obtains, exports and screenshots, and personal data in unmarked free text.
Whether destroying a key counts as erasure for you is for your data protection officer to decide. This is a design, not legal advice.
