The check

Every figure — traced or held.

Your domain is your workspace.

Sign in with your work email. The one-time code proves you belong to the domain — and the workspace opens already carrying that team's voice, sources and never-say list. Sign in from any other address and you never see it.

01 Your voice Three to five published pieces plus a short intake. Inkstone drafts a guide; you edit it. Every draft is checked against it.
02 Your sources The authorities and archives your beat relies on, lifted up the tier ladder. Your own numbers sit at Tier 0, above everything else.
03 Your guardrails The claims you can't make and the phrasing you don't use. Enforced on every draft; flagged the moment the model drifts.
