DDEALDigital Evidence Assertion Laboratory
Institutional protocol layer

Evidence that can move between systems.

DEAL exposes read-only institutional APIs and portable research bundles without reducing the evidence chain to a screenshot, analyst note or unverifiable model summary.

Institutional workflow

From evidence engine to research infrastructure.

DEAL's public interface explains the evidence. The institutional layer exposes the underlying artifacts directly.

APIScoped read access

Machine-readable research

Retrieve node status, compiled research plans, reports, DEAL Records, model registries, dataset contracts and bundle inventories through organization-bound credentials.

X-DEAL-Key: deal_live_… GET /api/institutional/research/{uuid}
BUNDLEPortable audit artifact

Research bundles

Package a research question, evidence graph, timeline, sealed DEAL Record, model artifacts, verification state and optional report into one downloadable ZIP.

VERIFYIndependent integrity

Trust the hashes, not the presentation

Every bundle carries component hashes plus separate manifest and archive SHA-256 values so downstream systems can verify what they received.

Research handoff

A clean institutional chain of custody.

The artifact that leaves DEAL remains bound to the evidence state that produced it.

Read-only by design

Institutional access without giving the API authority to rewrite evidence.

v0.1.10 credentials expose research, model, catalog and audit artifacts. Evidence mutation remains inside controlled DEAL workflows.
