0. Scope, Non-Goals, and Document Conventions¶
0.1 Scope¶
This document specifies a baseline architectural standard for Reconstruction-Grade eDiscovery in collaborative cloud environments. The standard focuses on the minimum properties required to preserve and export evidence such that reconstruction is deterministic, auditable, and reproducible.
0.2 Non-Goals (Out of Scope)
This standard does not:
- Provide legal advice or define admissibility standards; it defines an architectural preservation and export baseline.
- Require or assume full-tenant "archive everything" capture.
- Mandate a specific vendor, product, cloud provider, storage backend, review platform, or deployment topology.
- Guarantee perfect behavioral visibility; audit evidence is explicitly bounded by licensing, retention, and upstream availability.
- Require semantic analytics, relevance scoring, or LLM-based workflows.
- Replace existing review platforms; it specifies what an upstream preservation record MUST provide to downstream systems.
0.3 Threat Model (What This Standard Is Designed to Withstand)¶
Reconstruction-Grade properties matter because evidence is evaluated under adversarial or high-scrutiny conditions, including:
- Court challenges to authenticity, completeness, proportionality, and chain of custody.
- Regulator inquiries requiring auditability and repeatability.
- Internal investigations where timelines, identity state, and access behavior are disputed.
- Repeat exports where differences MUST be explained without operator narrative.
This standard assumes that any ambiguous, inferred, or non-reproducible claim will be challenged. Therefore, it prioritizes:
- Deterministic resolution rules and explicit fallback documentation.
- Stable identifiers and relationship bindings.
- Explicit exceptions (no silent drops).
- Export manifests with hash and integrity support.
- Clear boundedness statements when upstream evidence is incomplete.
0.4 Normative Language¶
This document uses MUST, SHOULD, and MAY as normative requirement levels:
- MUST indicates a required property for Reconstruction-Grade conformance.
- SHOULD indicates a strong recommendation that materially improves reconstruction.
- MAY indicates an optional capability that can improve outcomes but is not required for baseline conformance.
