A dossier that stays honest across years.
Second Trace holds the fragmented record of a cold case in one disciplined structure: sources, claims, timelines, relationships, and analysis — each traceable, each uncertain where uncertain.
01
Provenance first
Every claim records its source, exact location, date obtained, and reliability. Nothing floats.
02
Uncertainty as data
Exact, approximate, disputed, range, unknown — these are first-class states, not edge cases.
03
Honest AI
Grounded in case-authorized material only; every finding cited, labeled, and human-reviewable.
04
Works for teams
Roles, invitations, review flows, and restricted notes — collaboration without compromise.
05
Safe by default
Tenant isolation, least-privilege access, append-only audit, encrypted backups.
06
Reports that hold up
Citation-complete exports that never convert allegations into facts.
How the workspace is organized
A case is a bounded inquiry. Inside it, the command center keeps the current state of questions, coverage, and next actions. The evidence library holds every item with its provenance and processing record. The timeline holds accounts — not merged truths — so disputes stay visible. The relationship workspace distinguishes source-cited edges from inferences that require a plain-language explanation and human verification.
Analysis surfaces — behavioral review, competing hypotheses, leads — all feed from the same cited record and all respect the same rule: an interpretation is labeled as an interpretation.
