Case workspaceDemo buildAug 2026
Cold cases persist. So does the record.
Second Trace is a workspace for organizing cold-case information with total provenance — evidence-backed timelines, source-cited claims, relationship analysis, and grounded assistance. Built so disciplined inquiry can continue across years without losing the thread.
Principles
01
Every fact traceable
Claims, accounts, and relationships carry their source and exact location.
02
Every uncertainty visible
Disputed, approximate, and unknown states are first-class — never smoothed over.
03
Nothing invented
AI output is labeled, cited, and requires human verification. Insufficient evidence is a complete answer.
Workspaces
One case, many instruments
Evidence
An editorial library with provenance, custody, and redaction.
Timeline
Exact, estimated, disputed — held side by side, never merged.
Relationships
Direct and inferred edges, each traceable to a source.
Maps
Uncertainty as an area, movement as a record, no false precision.
Behavior
Provisional patterns with verified and reported states.
Hypotheses
Competing explanations with falsification criteria.
Leads
Transparent priority from lawful, adjustable factors.
Reports
Citation-complete, claim-honest, print-ready.
Responsible by design
Presumption of innocence is not a banner. It is the system.
Second Trace describes people neutrally until a source establishes a role. It never scores guilt, never ranks suspects, and refuses to convert allegations into facts. Built for lawful research and authorized casework only.
