Evidence Architecture
Evidence Architecture is StackWeaver's three-layer model describing the full lifecycle of compliance evidence: (1) Created & Captured at the source, (2) Stored & Connected across systems and mapped to controls, and (3) Verified & Consumed on demand by auditors, regulators, and investors.
Explanation
Layer 1 -- Created & Captured: evidence is generated by the work teams already do (deploys, tests, access events, approvals) and captured automatically, not screenshotted.
Layer 2 -- Stored & Connected: evidence is centralised, deduplicated, and correlated so a single record can satisfy multiple controls and frameworks at once, with integrity guarantees.
Layer 3 -- Verified & Consumed: the stored evidence is exposed through views tailored to each consumer -- an auditor sees control coverage, an investor sees posture, a regulator sees filings -- without a manual export.
Why it matters
Most evidence problems are architecture problems: proof exists but is scattered, unmapped, or stale. A defined architecture makes coverage and freshness visible.
Mapping once and reusing across frameworks is what makes multi-framework readiness economically viable for a startup.
How StackWeaver applies it
StackWeaver designs and implements each layer for the client, choosing capture points, integrity model, and consumption views appropriate to their frameworks and stage. The Evidence Lifecycle walkthrough traces one record through all three layers; the Control Mapping evidence shows Layer 2 in action.
The Evidence Automation solution implements the capture and validation layer; the Client Portal Walkthrough demonstrates the consumption layer for auditors and investors; the Trust Readiness Playbook provides the full multi-framework implementation roadmap.
Key points
Layer 1
Created & Captured -- evidence is generated by the work teams already do (deploys, tests, access events, approvals) and captured automatically, not screenshotted.
Layer 2
Stored & Connected -- evidence is centralised, deduplicated, and correlated so a single record can satisfy multiple controls and frameworks at once, with integrity guarantees.
Layer 3
Verified & Consumed -- the stored evidence is exposed through views tailored to each consumer: an auditor sees control coverage, an investor sees posture, a regulator sees filings, without a manual export.
What this relates to
- Evidence-Native SystemsSystems where compliance proof is a property of how they operate -- captured at the source -- not a document produced under deadline.
- Evidence ObjectA single, verifiable record of correct operation, captured at the source and mapped to one or more controls.
- Evidence PackageA scoped, auditable collection of Evidence Objects mapped to a specific framework, engagement, or stakeholder request.
- Evidence IntelligenceThe analysis layer over collected evidence that surfaces coverage gaps, control drift, freshness, and readiness -- turning raw records into decisions.
- Trust InfrastructureThe market category StackWeaver operates in: technology able to continuously demonstrate that it can be trusted, not just claim it.
- The Evidence LifecycleA visual walkthrough of how a single piece of compliance evidence is created, connected, and consumed — from an engineering event to an auditor's verification.
- Control Mapping: One Evidence Base, Many FrameworksHow a single evidence base maps to multiple frameworks at once — the mechanism that makes multi-framework readiness economically viable for a startup.
