Sift decision traces
Private platform work
At Sift, I worked on systems that traced derived decisions back to the source context that produced them. The trace model carried source IDs, source types, timestamps, authors, channels, and roles such as Proposal, Context, Objection, Validation, Pivot, and Resolution.
Replaced flat underlying-discussion data with chronological decision traces.
Connected decisions to source messages, conversations, and meeting transcripts through graph relationships.
Scoped decision access by organization, user, and private-channel membership.
Treated provenance as part of permissioning, because private source content can leak through derived AI knowledge.
