DataHub Agent Hackathon 2026 Operation Kintsugi / Synthetic

THE REGULATORY COMPILER FOR DATA + AI

Every policy change becomes a provable action.

PolicyLineage compiles primary-source evidence and live DataHub lineage into a deterministic verdict, an approval gate, and a reusable audit trail.

ONE CLOSED LOOP / NO CHATBOT THEATER

A policy does not name the dataset that must act.

PolicyLineage turns that missing translation into an inspectable machine process. Every transition preserves source, scope, uncertainty, ownership, and approval.

PROBABILISTIC

Extraction proposes typed rules.

DETERMINISTIC

Tested code owns the verdict.

01 / PRIMARY SOURCE Atomic conditions restriction · exception · effective date

02 / DATAHUB GRAPH Observable dependency schema · lineage · owner · tag · assertion

03 / DETERMINISTIC GATE BLOCK impact priority 100 / evidence coverage 84%

04 / HUMAN-GOVERNED ACTION Preview → approve → write back attributable · idempotent · revalidatable

CAPTURED RUN / 02:44

The proof moves because the system moves.

Real compiler output, captured from the synthetic Operation Kintsugi scenario. No mock verdicts and no hidden legal conclusion.

AUDITED DEMO

PolicyLineage opening screen — 01 / POLICY

BLOCK decision with impact metrics — 02 / VERDICT

DataHub lineage and evidence ledger — 03 / LINEAGE

Evidence and governed writeback plan — 04 / APPROVAL

ALLOW decision superseding prior evidence — 05 / REVALIDATE

OPERATIONAL SIGNAL 100

Impact priority index

How urgently observed dependencies require action.

EVIDENTIARY SIGNAL 84%

Evidence coverage index

How completely the current record supports this decision.

Exposure and evidence confidence are never collapsed into one score.

WORKING PRODUCT / ZERO-SECRETS REHEARSAL

Do not take the claim on trust. Run it.

The public mode compiles a synthetic policy pack against a deterministic DataHub-shaped graph. The authenticated Control Plane adds workspaces, roles, audit events, and PostgreSQL persistence.

Ready to trace policy impact

The compiler will test the notice against schemas, governance signals, owners, and multi-hop lineage.

02 / IMPACT GRAPH

One policy clause. Every downstream consequence.

03 / EVIDENCE LEDGER

Claims tested both ways

FALSIFIABLE

04 / GOVERNED ACTION

Writeback plan

APPROVAL REQUIRED

Nothing mutates the catalog until a responsible human approves this exact evidence bundle.

05 / DECISION REGISTRY

Every verdict keeps its audit trail

DURABLE

Decision bundles, approval state, and supersession links remain independently inspectable. DataHub stays the shared organization record.

POLICYLINEAGE CONTROL PLANE / v0.2.0

One decision graph.
Every responsible operator.

Workspace isolation, least-privilege API keys, PostgreSQL persistence, attributable audit events, and durable revalidation turn the demo into an operational SaaS foundation.
