The tactician needs it. Stonewall ships it.
Stonewall is a litigation knowledge system: a source-grounded corpus, a live operational data plane, and a retrieval-first chronicler — wired across the public surface, the operator cockpit, and a Telegram bot, on a main branch that is never red.
Four things worth the look
Not a toolchain inventory — the systems that make the record hold. Pick one.
A live Postgres data planeNeon Postgres
A Neon Postgres data plane mirrors the entire corpus and carries Shelby's durable memory. The flat-file manifest stays the source of truth; Postgres is the queryable projection beside it — artifacts, patterns, and source markdowns, indexed for millisecond reads.
- Durable per-operator memory + thread history
- Corpus projection tables (artifacts · patterns · sources)
- Read-only Neon role behind row-level security
- Idempotent, schema-versioned migrator
Ask it something hard.
A demo exchange in the house voice. The fact pattern is borrowed from Hollywood’s favorite automotive cross-examination; the mechanics are real — Shelby walks the record artifact to artifact and pins every claim to an ID, a source path, and a line range.
The State’s expert says any mid-’60s GM could have laid down those two tire marks outside the convenience store, so the defendants’ metallic-mint convertible is as good as a confession. Settled fact, or is there something in the record?
It is a trick question, counselor — and the record answers it. Let me pull the chain before I opine.
The scene photographs show two parallel burn marks, equal in length and equal in intensity A0064· L112–L118. Equal marks mean both rear wheels were driving. That requires a limited-slip differential — positraction — and positraction was not available on the defendants’ 1964 Buick Skylark A0071· L23.
Second link in the chain: the marks leave the road flat over a curb cut — no fishtail, no hop. A solid-axle car cannot do that; the left tire lifts and the mark breaks. Independent rear suspension, or it did not happen A0071· L88–L96.
Walk the co-occurrence, and in the mid-’60s GM built exactly two cars carrying both: the Corvette — which no eyewitness mistakes for a Skylark — and the 1963 Pontiac Tempest A0112· L14. Same body length, same convertible top, same metallic-mint green in every witness photograph A0130· L7–L9.
The chronicle does not say the defendants are sympathetic. The chronicle says the car in the record is not their car. The record holds.
Demo fact pattern (a 1992 courtroom classic); fictional manifest rows. Against the live corpus the same chips resolve to real artifacts — 2,568 of them — and open the source at the cited line.
