Field guide · Legal
Law runs on a torrent of timestamped evidence; every filing, every ruling, every deposition, and the entire cloud of news, filings and posts around them. Each one is a dated fact you can anchor on a timeline and connect to others. The pile isn't the value. The relationships are.
One lawsuit as the machine sees it · the court record and the world's reaction · on a single clock
01 · The evidentiary torrent
At the bottom sits everything. Pleadings and dockets. Testimony: depositions, witness statements, expert reports, interrogatory answers. Exhibits and productions with their chain of custody. The people: parties, counsel, firms, judges, jurors, witnesses, experts. The instruments: contracts and their individual clauses, patents, statutes, regulations. And the ambient signal: news articles, press releases, social posts, analyst notes, SEC filings, regulatory actions. Each one is a small, dated, typed fact; the legal version of a single heartbeat.
Everything a matter touches, read once · then distilled into typed, dated facts that carry their evidence with them
Inside one document
A deposition can run 600 pages. Nobody reads all of it twice; but buried inside are the moments that matter: an admission on page 212, a contradiction of an earlier statement, a date that anchors everything else. The system reads the document once, lifts each moment out as a typed, dated fact, and every fact keeps its anchor; the exact page and line it came from. The 600 pages step out of the working path. The meaning stays, with a pointer back to its proof.
Three facts out of six hundred pages; each one carrying the exact page and line it came from. The document is the tape; the facts are what's kept; the anchor is the proof.
The full record
A trial runs for weeks. The record runs for months; hearing after hearing, witness after witness, thousands of pages of transcript, hundreds of exhibits and rulings. Today, a person reads it front to back to find out where anything is. But once every day of testimony has been read once and lifted into anchored facts, the record stops being a pile you read and becomes a memory you ask. Every moment across every day sits on one clock; so “find every time the defect was discussed” or “show me the afternoon of day 14” is a query, not a week of billed reading.
Six weeks of trial, one question. Every answer points to the exact day, page, and line; so checking the machine's work takes seconds, not a re-read.
02 · The recurring characters
Nothing connects without people. Attorneys, firms, judges, and expert witnesses thread through hundreds of matters, and a repeat player is a relationship spine. You can follow a judge the way a trader follows a stock: what comes before them, how they rule, always compared to their own normal. The same is true of a firm, or an expert who keeps showing up for one side.

03 · The connective tissue
03a · Co-occurrence
Two firms repeatedly across the table. Clauses that always travel as a block; boilerplate that moves together by construction, flagged honestly as mechanical, not meaningful. An expert who only ever appears with one firm.
Every edge is scored against what chance would produce. Big counts can be meaningless; small counts can be signal. The label states which, and the numbers are the receipt.
03b · Citations
When one opinion cites another, the connection explains itself; the cite says why. Precedent flows forward; doctrines strengthen or erode; 'is this still good law?' becomes a question with an answer.
A citation is a relationship with the reason built in · and the graph knows when a case dies
03c · Families
Cases that cite each other in clusters form a body of law. Contracts drafted from the same template form a family. Even expert-witness networks cluster. The machine finds these groups from the connections alone; nobody hands it a taxonomy.
Doctrines, templates, and expert networks emerge as families · found, not filed
03d · Sequences
The sharpest question isn't 'what appears together?'; it's 'what happens next?' What usually follows a motion to dismiss granted with leave to amend? The machine finds every time that sequence occurred and reports what actually followed; with honest statistics, including when the honest answer is 'nothing unusual.'

04 · Every kind of evidence
A car accident produces a police report, two witness statements, photographs taken at the scene with timestamps in their metadata, a repair estimate, an insurance claim, and later a filing. Different forms; text, image, document; but every one is a dated fact that anchors to the same clock. The photo taken at 4:47pm sits on the timeline next to the witness statement describing 4:45pm, and a contradiction between them is now something the machine can see.
Witness statements, photographs, reports, claims; every form of evidence, one clock. When two facts disagree, the timeline is where it shows.
05 · Outcomes, recorded
Verdict, damages, settlement, dismissal, remand, sanctions, consent decree, injunction, fee award, reversal on appeal. These are the returns of the legal world; recorded from what happened, never predicted.
Recorded, not predicted
06 · The honesty layer
Not 'this judge grants 60% of these motions'; but compared to her own baseline, and the circuit's. Every mined pattern faces a holdout of cases it never saw. A sequence seen six times proves nothing. When you test a thousand patterns, some look real by luck; so findings must survive out-of-sample. And the most important thing a system can record is the honest null: this pattern predicts nothing. A tool that never says 'coincidence' is selling you noise.
Grant rate 2.1× this judge's own baseline. Holds out-of-sample across withheld cases, survives multiple-comparison correction.
Viral-thread → outcome: no relationship. Recorded as knowledge, so nothing chases it again.
