Matter DeskEvidence Locker
Matter Desk private pilotEvidence preservation & disclosure

Preserve the record before it changes.

Evidence Locker is a dedicated workspace for material you are authorised to provide. Every item is captured read-only, SHA-256 hashed when it arrives, and recorded in a tamper-evident custody ledger before review or disclosure begins.

Source access is read-only. The locker never sends, deletes or modifies source material.

Managed, dedicated firm pilot

Evidence infrastructure

Originals stay original. Work stays governed.

Preservation is deliberately separated from drafting and research. Downstream work can use an approved record without altering the evidence layer.

Capture with a digest

Each item receives a SHA-256 digest when it reaches the locker. Original bytes are stored separately from review and evidence manifests.

Deterministic capture path

Verify custody

A hash-chained ledger records capture, access, review, checkpoints and disclosure. A changed event makes verification fail visibly.

Tamper-evident event chain

Control disclosure

Counsel releases Bates-labelled evidence manifests to a chosen audience. Only records currently marked relevant are eligible, and future portal access can be withdrawn.

Audience-scoped access

Workflow

From intake to a controlled record.

The integrity path does not depend on AI. Search and discovery can be additive, but capture, hashing and custody remain deterministic.

01

Intake & capture

Open a matter, upload files or connect an available source. Authorisation and acquisition are recorded.

02

Hash & review

Original bytes are digested and custody-logged. Counsel classifies items and creates Bates-labelled evidence manifests.

03

Disclose & verify

Release only selected manifests, re-walk the event chain and record a checkpoint for the collection state.

For firms

A dedicated evidence workspace for one firm.

The private pilot gives one firm an isolated workspace while the Matter Desk product integration is completed and reviewed.

Matter DeskCompatibility path

Built to become a module

The interface shares Matter Desk’s product language and keeps evidence isolated. Secure matter links, single sign-on and entitlements remain explicit release gates for an integrated subscription.

  • Shared product system
  • Separate evidence boundary
  • Governed handoff design

Proof you can inspect

The product reports what it can prove: digest recorded, event appended, chain verified, evidence manifest created and access logged.

Content-addressed originals

Identical bytes resolve to one stored blob while every source and custody event remains separately recorded.

AI-free integrity path

Capture, hashing and custody are deterministic code. Semantic discovery is additive and never part of an integrity digest.
