Public/Private Report Projection and Sample Artifact Direction

Summary

ERT's reporting work is moving toward deterministic public/private report projection. This stage connects the completed Level 2 interpretive stack with the KACHE/KAN-like report-boundary scaffold.

The result is a clearer path for public-safe sample artifacts, client-private reports, and later suite automation.

What Changed

ERT now has three major public-facing layers ready to be represented in sample artifacts:

1. Level 1 baseline-controlled diagnostic artifacts
2. Level 2 interpretive diagnostic reads
3. KACHE/KAN-like report-boundary projection

The next practical step is not more conceptual expansion. The next step is to show stable report examples.

Sample reports should demonstrate baseline context, diagnostic status, Level 2 read summaries, response-state rhythm, observer disagreement summary, public/private report separation, and public-safe boundary notes.

Public Report Model

A public ERT report should be understandable by a reviewer without exposing protected mechanics.

Public reports may include:

run status
baseline summary
risk/confidence/consistency summary
public diagnostic status
Level 2 public summaries
Response-State ECG public summary
Observer Disagreement public summary
public report boundary note

Public reports should not include protected diagnostic internals, hidden prompt/probe details, raw private vectors, protected thresholds, or internal sequencing mechanics.

Client-Private Report Model

A client-private report may provide more explanatory context than a public report, but it should still be sanitized.

It should be suitable for a client, evaluator, or internal stakeholder who needs more detail about the diagnostic result without receiving protected evaluator mechanics.

Client-private reports may explain why a read returned watch, stable, inconclusive, or not applicable; how Level 1 and Level 2 relate; whether more runs are recommended; and whether a sample, medium, or full diagnostic suite is appropriate next.

Development-Only and Local Views

ERT may maintain development-only audit information and local internal views for engineering validation. Those views are not regular reports.

Regular reports are generated from sanitized report models only.
Development-only audit views are not public report content.
Local internal views are not public report content.

This makes the report system easier to inspect because each output has a defined audience and boundary.

Report Shape Fixtures

After the report boundary is stable, ERT should add golden report-shape fixtures.

These fixtures help catch accidental changes to public report fields, client-private report fields, Level 2 read order, public/private boundary behavior, report projection source, and the absence of development-only audit data in regular reports.

Suite Automation Direction

Suite automation should come after report-shape fixtures and sample artifacts.

A future ERT interface may support run modes such as Generate Sample, Generate Diagnostics Only, Generate Medium Suite, Generate Full Suite, and Generate Full Hard Mode.

Manual override should remain available for expert use. Euclidean/linear geometry can remain the default ordinary scoring path while other paths stay explicitly selectable, labeled, or gated according to their status.

Recommended Next Artifacts

1. Sample public Level 1 + Level 2 report
2. Sample client-private report
3. Public/private redaction comparison
4. KACHE/KAN-like boundary public note
5. Report-shape fixture documentation

Public Note

ERT reports should be read as diagnostic evidence, not universal guarantees. The public report should explain what was observed, what was interpreted, what remained uncertain, and what was intentionally withheld from public disclosure.
