Sherlock Orbit is an autonomous investigation system for police and investigative teams. A squad of 13 specialist agents works a case end to end: it reads every document, extracts claims with passage-level citations, builds the timeline, weighs competing explanations, analyses CCTV, phone and location records, plans and runs consented witness interviews, and drafts the case report. The problem: investigators lose most of their time to paperwork and cross-checking, and the AI tools that could help are unsafe in a legal setting. They hallucinate, obey instructions hidden in evidence, and act without authority. Orbit is built so autonomy never means unaccountability. Every claim links to its source passage. Evidence is stored read-only with SHA-256 fingerprints and a hash-chained audit log. Prompt injections inside evidence are treated as data, never as orders. Authority is checked in code: third-party CCTV, warrants and interviews wait for the right human to approve. Conflicting witnesses are logged as open questions, never as accusations of lying. Nothing leaves the system until a named supervisor signs it. It includes team sign-up with optional two-factor authentication, and a separate Demo Mode that replays a full fictional investigation with one click.
