SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill eliminates the manual effort of building a litigation chronology by extracting dated events from disclosed or production documents and organizing them into a matter-ready timeline.

Core Features & Use Cases

  • Matter- or production-centric chronology building: Build from declared matter sources (theory, key facts, document storage sources) or from production/eDiscovery exports (custodian/date/Bates manifests).
  • De-duplicated, provenance-tagged events: Merge repeated events across multiple files and attribute each entry to its exact source (file path, Bates range, or connector retrieval).
  • Significance and privilege gating: Tag events by significance (🔴/🟡/⚪) per the case theory pivot fact and enforce a privilege posture gate (A-cleared, B-mixed with per-entry flags, or C-aborted).
  • Statement-of-facts variant and witness filtering: Produce an SoF-ready narrative skeleton filtered for external use and optionally generate witness-specific timelines.

Quick Start

Use the chronology skill to build a working chronology for the current litigation matter from your declared document sources and uploads.

Frequently Asked Questions about chronology

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I build a litigation chronology from eDiscovery production documents?

To build a litigation chronology from eDiscovery productions, the Skill extracts dated events from Bates sets and custodian manifests, de-duplicates them, and organizes them into a tagged timeline. It attributes every entry to its exact Bates range or connector retrieval source.

What is the best way to de-duplicate events in a statement of facts timeline?

De-duplicating events in a statement of facts timeline requires merging repeated occurrences across multiple files. This Skill automatically consolidates duplicate dated events and tags each remaining entry with provenance, linking it to the exact file path or Bates citation.

Can I tag litigation chronology events by significance and case theory?

Yes, you can tag litigation chronology events by significance according to your case theory. The Skill assigns priority indicators (🔴/🟡/⚪) to events based on their relevance to pivot facts, and can generate a filtered statement-of-facts narrative skeleton.

Does this chronology builder enforce a privilege gate for discovery documents?

Yes, a mandatory privilege posture gate is enforced for all discovery documents. The Skill requires selecting an A-cleared, B-mixed with per-entry flags, or C-aborted privilege posture before processing, ensuring privileged information is handled correctly in the final timeline.

How do I generate witness-specific timelines from a matter history extraction?

To generate witness-specific timelines from a matter history extraction, the Skill filters the consolidated chronology by custodian or witness names. It processes your declared document sources and matter theory to produce targeted, isolated timelines for individual witnesses.

Are chronology file updates tracked with versioned diffs?

Yes, chronology file updates are tracked with versioned diffs. The Skill writes an updated chronology file after each extraction or modification, preserving provenance tagging for every legal and date assertion while maintaining a clear record of changes.
