What it produces
- Integrity records: structured JSON evidence objects for interaction trajectories.
- Cross-evaluator evidence: parallel records across evaluators without adjudication.
- Temporal causality: ordered lineage across time (no overwrites; append-only).
- Evidence bundles: signed bundles with manifest + recompute instructions.
What it does not do
- No output correction: HER₂™ does not regenerate or “fix” model responses.
- No scoring authority: no certification, ranking, or compliance determination by default.
- No model lock-in: works offline/CI/runtime; vendor-agnostic evidence layer.
HER2NI Protocol v1.0 (DOI)
Delivers
- Recomputable interaction integrity records
- Evaluator-agnostic evidence preservation
- Temporal causality and lineage (append-only)
- Signed manifests and verification material
Scope
- Licensed, case-scoped engagement
- Offline / CI / agent-runtime compatible
- JSON-first, vendor-neutral artifacts
Primary Users
- Audit & Compliance Firms
- Litigation Support & Expert Witness
- Banks, Fintechs & Insurers
- Venture Capital & Private Equity
Engagements are evidence-only by default.
Any compliance opinion, certification, or expert report is a separate engagement.
Who uses HER₂™
HER₂™ is built for organizations that need independent reconstruction of AI behavior — where dashboards, vendor logs, and post-hoc explanations are not enough.
Venture Capital / Private Equity
Your world: You assess AI companies fast, using demos and claims.
Missing capability: durable proof of model behavior during diligence.
HER₂™ delivers: recomputable evidence artifacts preserving exactly how a system behaved under defined conditions.
Banks, Fintechs, Insurers
Your world: AI is deployed where decisions must be defensible.
Missing capability: forensic reconstruction for audits and disputes.
HER₂™ delivers: non-normative interaction evidence you can verify and replay independently.
Audit & Compliance Firms
Your world: You review controls and governance frameworks.
Missing capability: independent reconstruction of model behavior.
HER₂™ delivers: immutable evidence records decoupled from vendors and execution environments.
Litigation Support & Expert Witness
Your world: AI disputes require neutral, inspectable records.
Missing capability: court-ready reconstruction without vendor control.
HER₂™ delivers: temporal lineage + recomputation paths for adversarial review.
Insurance Underwriters
Your world: You price risk and investigate incidents.
Missing capability: post-incident reconstruction of AI behavior.
HER₂™ delivers: consistent evidence artifacts for loss analysis and recurrence assessment.
Policy Labs & Think Tanks
Your world: You evaluate governance proposals and AI accountability.
Missing capability: an evidence substrate that doesn’t interfere with models.
HER₂™ delivers: verifiable records for research, oversight, and standards work.
How it works
JSON-first
Signed bundle
Recompute instructions
Cross-evaluator optional
Temporal lineage
HER₂™ produces a chain of evidence by binding declared inputs, outputs, evaluator identity/config, and ordering metadata into a verifiable artifact.
Records are designed to be portable and inspectable without relying on vendor internals.
Operational constraints
- Works offline, in CI, or inside an agent runtime.
- No external APIs required for the core evidence layer.
- Does not require access to model weights or training data.
Note: LLM nondeterminism is expected. HER₂™ records what happened, and enables replay/recompute under declared conditions—without asserting correctness.
Important notes
- Evidence-only by default: no certification, ranking, or compliance determination unless separately contracted.
- No model interference: HER₂™ does not modify weights, suppress outputs, or enforce decisions.
- Not clinical: not a diagnostic system and not medical advice.
- Vendor-agnostic: designed to be independent of provider custody and proprietary logs.
In litigation, an audit, an incident, or a dispute, narratives collapse — only recomputable records remain.
Dashboards are not reliable evidence.
HER₂™ turns the interaction trajectory into cryptographically verifiable evidence.
HER₂™ is your evidence layer.
