No
Enable full writes (distribution, takedowns, immutable uploads). Disabled by default; also requires LABELGRID_FULL_WRITES_ACK.

Must equal the exact acknowledgment sentence (see the README safety section) to arm full writes.
LABELGRID_TOOLSETS

LABELGRID_READ_ONLY
No
Force reads only; overrides both write flags. Defaults to false.
