TCRIA

TCRIA is a governance-oriented system for legal evidence processing.

It is designed to help organize heterogeneous legal materials, preserve documentary traceability, and generate auditable bundles without turning the system into an automatic accusation engine. The core objective is to keep evidence processing structured while leaving legal judgment and narrative responsibility with the human operator.

Executive summary

TCRIA helps teams and operators:

• ingest mixed legal document collections;
• classify documentary artifacts;
• record traceability and governance signals;
• block or warn on risky accusatory content;
• generate auditable outputs in JSON, Markdown, and PDF.

The project is intentionally focused on organization, chain of custody, and governance discipline.

What the system does

TCRIA treats document processing as a custody workflow:

1. document ingestion;
2. classification;
3. traceability signals;
4. governance gates;
5. audit bundle generation.

This makes the system useful for:

• legal audits;
• investigation support;
• evidence organization;
• documentary review workflows;
• controlled preparation of governed case materials.

Governance boundaries

TCRIA is built around a simple rule: automation can organize and audit evidence, but accountability for accusatory narrative promotion must remain human-declared.

The system therefore applies governance checks such as:

• prescriptiveGate — blocks condemnatory or prescriptive language;
• complianceGate — requires explicit human accountability metadata in strict mode;
• traceabilityCheck — looks for dates, references, markers, and evidence signals.

What TCRIA does not do

TCRIA intentionally does not:

• generate legal pleadings;
• write accusations automatically;
• construct legal theses autonomously;
• replace human legal judgment.

Repository structure

The repository is organized so that code, operational scripts, documentation, and example artifacts are visually separated.

Architecture note

The architecture overview in docs/architecture-overview.md is kept as the project’s current high-level representation. Operational implementation remains package- and script-oriented, and the repository structure is organized to support that working style cleanly.

---

Sample artifacts and snapshots

To keep the repository root clean and professional:

• curated generated sample outputs are stored in examples/audit-artifacts/;
• project-structure snapshots and diffs are stored in docs/project-snapshots/;
• runtime outputs can continue to be generated in local working directories such as output/ or case folders.

---

Current professionalization goals

This repository now prioritizes:

• consistent structure;
• executive README presentation;
• visual separation between code, scripts, docs, and artifacts;
• predictable folder naming;
• less noise in the repository root.
