TACITUS / AI data infrastructure

AI data infrastructure
for policy analysis.

TACITUS is building AI data infrastructure for policy and political analysis: source evidence, structured knowledge and reusable context.

Working tools / public repositories

Explore the infrastructure.

Query historical records, inspect their sources and reopen a research selection. Both tools run locally.

01 / Historical research

Middle East research atlas

Explore 120,576 UCDP GED 26.1 event records for 2000–2025 and 15,272 non-null annual World Bank values. Inspect original fields, filter by place and time, then export a bounded research selection.

  • Map and time filters
  • Five source-backed semantic lenses
  • Research selection export

Annual country series retain units and missingness. The separate curated desk has 55 source profiles and 228 context records. Historical rows retain provider classifications; they are not reviewed political claims or a live feed.

GitHub Run locally

02 / Inspectable context

TACITUS Context explorer

Open an exported native Context or a historical research selection in its own reader. Inspect source records, versions, units and qualifications, then download the unchanged input bytes.

  • Native Context: seven layers
  • Research selection: source records
  • Unchanged JSON download

Read-only browser viewer · no model generation or native query.

Recurring analytical work / intended users

Keep what a capable newcomer
might otherwise miss.

Has this rule actually taken effect? →

Who needs this? A consultancy analyst briefing a steering group.

What carries forward? Source versions, authority, proposal modality, optionality and the reviewer’s correction.

Inspect the distinction and example

Typical failure: A January proposal or July option becomes a claimed obligation.

S01 proposes January; S02 requests transition; S03 considers July. Adoption and optional pilot funding stay unresolved. Apply the Legislative stage check and review a qualified brief.

Which name is appropriate here? →

Who needs this? A conflict researcher or humanitarian policy editor.

What carries forward? Entity/alias evidence, attributed designation, jurisdiction, audience style and analysis date.

Inspect the distinction and example

Typical failure: An unverified alias becomes an entity match or a jurisdiction-specific designation becomes global.

The fictional Group Q exercise flags alias, global-scope and stale-date errors. Fictional B is not checked, rather than “not designated”. Published and captured notices remain separate.

Can another analyst continue this brief? →

Who needs this? A research director facing a staff change or a second assignment.

What carries forward? Pinned sources, useful correction, reviewed revision, open questions and source handling limits.

Inspect the distinction and example

Typical failure: A polished answer travels without the decisions and qualifications behind it.

Save and reopen a local context revision, fork it and preview a JSON handover. The next task retains the correction but requires source, rights and applicability review.

PRAXIS / paused agentic workspace

Review a source
and keep the correction.

The recorded demonstration follows a document through capsule review, saved context and conversation attachment.

Example Advisory / synthetic local demonstration

A specialist distinction.
A better brief.

Brief a steering group by Day 16. Inspect the sources, apply a scoped method, review the proposed wording and carry the correction into the next task.

Runs deterministic browser checks on authored material. The real PRAXIS tour is separate. No model, live research, expert endorsement or customer result is implied.

Open the briefing workbench

Carry the work forward

Keep the correction.
Recheck what changed.

A local saved capsule carries the question, source revisions, method, dependencies and reviewer reservation. The successor reviews applicability and missing evidence before using it. A changed source marks only its declared sentence descendants as potentially stale.

Save, reopen and inspect a handover →Context and reference formats →

The browser demonstration implements local reuse. Full production sharing, lossless graph interchange and automatic app change review remain development work.

Legislative stage check

A reusable review method for policy briefs: identify authority, preserve conditions and ask which instrument would justify stronger wording.

Example Advisory needs a decision-ready explanation for the client steering group by Day 16. The mandate is geopolitical-risk advice, not legal assurance.
