Immutable Data Policy

1. Purpose of Immutable Data

Immutable data ensures that:

• authorship cannot be falsified
• records cannot be erased to hide wrongdoing
• lineage cannot be tampered with
• proof bundles remain trustworthy
• timestamped history remains intact
• scientific and civic institutions can rely on consistent datasets and models
• provenance evidence holds up in audits, investigations, research, or legal contexts

Without immutable data, provenance would lose its evidentiary value.

2. What Data Becomes Immutable

The following categories of metadata become permanently immutable once processed through the SOVEREIGN\PROVENANCE engine or archived externally:

A. Cryptographic Hashes

• SHA-based content fingerprints
• version hashes
• model/dataset checksums

B. Timestamp Receipts

• OpenTimestamps commitments
• third-party timestamping proofs
• system-generated time anchors

C. Provenance Manifests

• creation metadata
• authorship-intent fields
• license fields
• sovereign zone classifications
• dataset/model passport fields

D. Lineage Logs

• version history
• derivative links
• revisions
• edit events
• training lineage and inference lineage

E. Archival Identifiers

• IPFS CIDs
• pinning references
• distributed storage locators

F. Synthetic Visibility Metadata

• declared AI involvement
• detected synthetic signals
• inference transparency
• AI-assistance flags

G. Integrity Records

• audit log entries
• integrity score snapshots
• provenance workflow IDs

Once created or archived, these cannot be deleted or altered.

3. What Data Remains Mutable

Not all user data is permanent. The following may be edited or deleted when requested:

• User Profile Data: name, email, organization, contact details
• Non-immutable Content Copies: Internal copies of content stored for workflow execution
• Account Data: Accounts may be closed; associated personal info is removed or anonymized
• Non-essential Metadata: UI preferences, logs not tied to proof workflows, non-critical analytics
• Sealed or Restricted Artifacts: While immutable provenance metadata persists, the artifact itself may be deleted or sealed from public visibility

4. How Immutable Data Interacts with Privacy Laws

A. GDPR (EU)

GDPR recognizes exceptions for scientific research, public interest archiving, legal defense, and data essential for the functioning of a service. Provenance fulfills several of these exceptions.

Right to Erasure (Article 17) does not apply to cryptographically archived data, data essential to the functioning of a lawful system, or public-interest records.

Right to Rectification does not apply to immutable blockchain-like data stores. Corrections are logged as new lineage entries, not retroactive edits.

Right to Access is fully supported; users may download all provenance data associated with their artifacts.

B. CCPA / CPRA (California)

CCPA exceptions include data essential to security, data used to detect wrongdoing, and data needed to maintain system integrity. Immutable data is protected under these categories.

Deletion requests apply only to personal profile data, non-immutable content, and non-critical logs.

C. VCDPA, PIPEDA, LGPD, and other global laws

All major privacy frameworks permit retention of security-critical data, audit logs, evidentiary records, archival and research data, and data required to operate a service in good faith. Immutable provenance metadata falls under these allowances.

5. Why Immutable Data Cannot Be Deleted

Immutable data persists because:

1. It preserves authorship and origin integrity
2. It prevents falsification and revisionism
3. It ensures accountability for AI-generated and synthetic content
4. It provides continuity across revisions and derivatives
5. It protects users against fraud, plagiarism, and misattribution
6. It ensures datasets and models retain scientific traceability
7. It is necessary for public-interest archiving and civic trust

The integrity of the entire provenance system depends on this permanence.

6. How Immutable Data Is Stored

Immutable data may be stored in:

• Architectural Layers: SOVEREIGN\PROVENANCE internal immutable stores, tamper-evident logs, write-once cryptographic records
• External Anchors: OpenTimestamps, third-party timestamp networks, distributed archives, IPFS, region-specific sovereign storage providers
• Redundant Proof Layers: Multiple anchors ensure no single-point failure, no revision capability, and global verifiability

7. User Responsibilities

Users must understand that:

• Immutable data is permanent
• Immutable proofs are public or semi-public
• Immutable data cannot be erased even if the artifact is removed
• Immutable metadata forms the evidentiary foundation for provenance
• Uploading sensitive or unauthorized personal information is prohibited

Users must not attempt to:

• delete immutable metadata
• circumvent archival workflows
• tamper with permanent logs
• falsify lineage or prior art

8. Correction, Dispute Resolution & Amendments

Corrections are logged as new entries, not retroactive edits.

Disputes regarding authorship claims, synthetic detection, or lineage attribution may be submitted for review by a provenance integrity officer.

Amendments: If metadata is factually incorrect (e.g., misdeclared name), a revision entry will be created. Original immutable records remain intact.

9. Account Deletion and Data Removal

When an account is deleted:

We delete:

• profile data
• stored artifacts (if not archived)
• non-essential metadata

We cannot delete:

• hashes
• timestamps
• logs
• lineage records
• manifests
• immutable archival identifiers

Users may request sealing, pseudonymization, or visibility restrictions for certain metadata, subject to feasibility.
