Why legal teams need data-centric trust
Ambiguous drafts
Which redline is final? Email threads rarely give a defensible answer.
Attachment risk
Inbound documents carry malware and active content into the firm.
Reconstruction cost
Rebuilding who-changed-what is slow, manual, and disputable.
OSDF solution architecture
Purpose-built capabilities layered on the open OSDF core and verification engine.
Scoped signatures
Protect clauses while permitting counterparty signature fields.
Revision lineage
Every committed revision is canonicalized, hashed, and parent-linked.
Portable timeline
Export a signed timeline of authorship, transmission, and signing.
Safe package
Passive format with no scripts, macros, or auto-fetched content.
