Source and Evaluation
⬡ HARD TRUTH
⧩ The hard truth:
In this framework, “truth” is not about being right; it is about being provably consistent.
immutable history
consistency check
final arbitration
Historical reliability: 100%
Cryptographic signature ✓ holds
but lies today
L2 cross-reference will fail against the primary logs ➔ forcing the L3 human override
That override becomes the new
⏺ The consistency paradox
If a source has a 100% historical reliability score but lies today, the cryptographic signature still holds—but the L2 cross-reference will fail against the primary logs, forcing the L3 human override.
That override becomes the new Ground Truth for the next cycle.
From "Truth Engine" to "Trust Governance System"
Your revisions address several governance concerns, but they also introduce new trade-offs.
The key question becomes:
What must be immutable: the fact itself, or the decision process surrounding the fact?
| Concern | Your Solution | Remaining Risk |
|---|---|---|
| Permanent storage of harmful data | Only cleared facts enter immutable storage. | You still need immutable metadata proving why a record was quarantined or deleted. |
| Sanctioned sources | Block before L2. | Sanctions lists change over time and may vary by jurisdiction. |
| Human accountability | DID + IP address + timestamp + liability. | Attribution is not the same as informed authorization. |
| Dangerous facts | Immediate destruction. | Destruction can create evidentiary, compliance, and audit problems. |
1. Ephemeral Quarantine Is Stronger Than Immediate Immutability
A robust architecture separates the evidence lifecycle into two distinct zones:
ephemeral evidence space
↓
canonical immutable space
However, avoid deleting all traces of quarantined records.
Instead, retain only non-sensitive metadata:
CREATE TABLE quarantine_audit (
event_id UUID PRIMARY KEY,
payload_hash TEXT NOT NULL,
source_did TEXT,
quarantine_reason TEXT NOT NULL,
disposition TEXT NOT NULL,
deleted_at TIMESTAMPTZ NOT NULL
);
This preserves accountability without retaining the underlying content.
Otherwise, you lose the ability to answer critical questions:
- Why was this fact rejected?
- Was the deletion policy correctly applied?
- Was the system manipulated?
- Did an operator abuse deletion privileges?
The content may disappear; the decision trail should not.
2. Sanctions Checks Need Versioning
A simple pre-validation sanctions gate creates temporal ambiguity.
T1: Source approved
T2: Fact submitted
T3: Source sanctioned
T4: Investigation occurs
You must be able to prove which sanctions dataset existed at the time of submission.
Log the following attributes:
- Sanctions provider
- List version
- Retrieval timestamp
- Matching rules used
sanctions_status = "clear"
sanctions_list_version = "OFAC-2026-06-20"
checked_at = "2026-06-20T14:23:11Z"
Without versioning, compliance decisions become difficult to defend.
3. Legal Liability Requires More Than Attribution
Recording a reviewer's DID, IP address, and timestamp establishes identity, but it does not prove:
- Authority to approve
- Jurisdictional scope
- Competency
- Awareness of consequences
Consider capturing additional context:
reviewer_role
approval_policy_version
justification
attestation_text
Example attestation:
"I attest that I reviewed the available evidence under policy version X."
Liability depends on process, not merely identity.
Also note that IP addresses may constitute personal data and therefore require retention policies.
4. "Destroy High-Risk Facts" Is the Most Dangerous Rule
The instinct is understandable:
Dangerous information should not exist.
However, absolute deletion creates several problems.
Legal Conflict
- Preservation for investigations
- Litigation holds
- Incident response
- Regulatory reporting
Security Conflict
- Attempted abuse
- Insider threats
- Malicious submissions
- Coordinated attacks
Operational Conflict
Without minimal metadata, you cannot improve detection systems.
A safer approach is:
detect
↓
classify
↓
cryptographically seal
↓
restrict access
↓
retain metadata
↓
delete content per policy
The highest-risk data often requires the strongest controls—not necessarily instant destruction.
In practice:
No backup
No cache
No recovery
should apply only to the content itself, while preserving:
hash
classification
source identifier
deletion rationale
retention policy reference
5. Revised Principle
Instead of:
The system destroys high-risk facts outright.
Consider:
The system destroys unauthorized content while preserving a non-sensitive, immutable record of the governance decision.
That distinction protects both privacy and accountability.
Ultimately, this architecture moves beyond a "truth engine" and toward a trust governance system.
- Facts are temporary.
- Decisions are durable.
- Policies are versioned.
- Accountability is immutable.
