Audit & Traceability

The Audit & Traceability layer defines how the c-ECO TDR system preserves the integrity, reproducibility, and legal defensibility of all data flows, analytical transformations, and prudential outputs.

Because threshold-sensitive governance depends on scientifically processed signals, every stage of the system must remain reconstructible. Traceability is therefore not a secondary compliance function, but a constitutive condition of epistemic legitimacy.

The purpose of this page is to define how raw observations, intermediate calculations, indicators, scores, and trigger activations are recorded, preserved, and independently auditable.

Within the TDR framework, no prudentially relevant output is valid unless it can be traced back to its evidentiary origin.

This principle applies across the full analytical chain:

Each layer must remain identifiable, reproducible, and historically reconstructible.

For any output to be considered admissible within the c-ECO framework, the system must preserve:

These conditions ensure that the relationship between scientific evidence and governance consequence remains transparent.

Data lineage refers to the full path through which a signal moves inside the TDR system.

This includes:

Lineage allows independent reconstruction of how a given prudential classification was produced.

Because TDR outputs may activate binding prudential consequences, records must be protected against silent modification.

The framework therefore relies on immutable or tamper-evident record structures such as:

Immutability does not require that no correction ever occur. It requires that any correction remain visible, attributable, and historically preserved.

Traceability requires explicit version control for:

Any change in methodology must generate a new identifiable version with full historical retention. This prevents silent methodological drift and preserves comparability across reporting periods.

A technically competent independent reviewer must be able to reproduce the same result from the preserved evidence package.

The minimum reproducibility bundle includes:

If the output cannot be reproduced, it cannot serve as a prudentially operative signal.

Audit trails record who performed each consequential operation, when it occurred, and under which procedural authority.

Typical auditable events include:

The purpose of audit trails is to ensure procedural accountability without weakening automation.

The framework must permit independent audit at multiple levels:

Independent audit is essential both for scientific credibility and institutional legitimacy.

The audit system must permit full historical reconstruction of any prudentially relevant event.

A reviewer should be able to answer questions such as:

This capacity is especially important in dispute resolution and post-event review.

Audit & Traceability is distinct from the Data Verification Body:

The DVB produces validated evidence. Audit & Traceability preserves and tests that evidence.

Within the TDR architecture, this layer underpins the credibility of all downstream functions.

It ensures that:

Traceability is therefore a precondition of trustworthy automation.

The objective of the Audit & Traceability layer is to ensure that every prudentially relevant output within the TDR system remains scientifically reproducible, procedurally accountable, and institutionally defensible.
