TG-ENRICH-CONTEXT
TrustGate Context Enrichment Engine
0. Identity
Depends on module:
1. Purpose
The TrustGate Context Enrichment Engine transforms a normalized TrustGate signal into a fully contextualized assurance object.
Unlike the preceding Parser and Normalizer engines—which focus on syntactic correctness and canonical representation—this engine establishes the complete operational context required for downstream trust evaluation.
The engine enriches incoming signals with:
- organizational identity
- historical assurance context
- governance policies
- replay history
- federation metadata
- lineage information
- AI-derived recommendations
- applicable schemas
- software provenance
- routing hints
The resulting object becomes the canonical TrustGate runtime entity processed by every remaining TrustGate micro-engine.

Enriched Trust Signal
5. Runtime Lifecycle
Each signal passes through the following lifecycle:
| Phase | Description |
|---|---|
| Receive | Accept normalized TrustGate object. |
| Resolve Identity | Resolve ECO, organization and DID metadata. |
| Resolve Lineage | Load DAL anchors and USO lineage graph. |
| Resolve Governance | Load applicable governance bundle. |

| Resolve AI | Load DSAIL recommendations and calibration state. |
| Resolve Replay | Load replay confidence and assurance history. |
| Merge Context | Produce a unified enrichment object. |
| Emit | Publish enriched signal for validation. |
6. External Dependencies
The Context Enrichment Engine is intentionally lightweight with respect to computation but highly connected.
| System | Purpose |
|---|---|
| ZAR | Resolve CMIs, CSIs, MEIDs, software artifacts and provenance. |
| USO | Retrieve operational lineage and event history. |
| DAL | Retrieve ledger anchors and verification proofs. |
| SSSR | Load canonical schemas and semantic mappings. |
| DSAIL | AI recommendations and adaptive calibration. |
| FAGF | Governance rules and active policy bundles. |
| EGFS | Federation metadata and node trust information. |
| AII | Historical assurance intelligence metrics. |
| OARM | Runtime overrides and policy exceptions. |
| ZSSR | Routing hints for downstream orchestration. |
7. Engine Registration
| Property | Value |
|---|---|
| MEID | MEID_SIGNAL_ENRICH_CONTEXT |
| CMI | vera.TG-ENRICH.ENGINE.CONTEXT.1_0_0 |
| Engine Type | Context Enrichment |
| Runtime Category | TrustGate |
| Registry | ZAR |
| Runtime Tier | Tier-0 Assurance Runtime |
8. Design Principles
The engine follows several architectural principles:
- deterministic enrichment
- replay reproducibility
- immutable enrichment records
- federation-aware context
- policy-driven enrichment
- AI-assisted but human-verifiable recommendations
- cryptographically verifiable provenance
- minimal latency
- horizontally scalable execution
- zero trust between federation nodes
Every enrichment decision must itself be explainable and reproducible during future replay operations.
9. Downstream Consumers
The enriched runtime object is consumed by:
- Schema Validation Engine
- Business Rule Validation Engine
- Trust Scoring Engine
- Decision Engine
- Replay Engine
- DAL Anchor Engine
- AII Engine
- Assurance Analytics Engine
- Federation Synchronization Engine
No TrustGate trust score shall be computed before successful completion of this enrichment stage.
10. Runtime Processing Pipeline
The Context Enrichment Engine executes a deterministic enrichment pipeline consisting of multiple independent enrichment stages.
Each stage contributes additional metadata while preserving immutability of previously attached context.

Emit Enriched Signal
The engine is intentionally modular so each enrichment stage may evolve independently while maintaining deterministic outputs.
11. Context Resolution Algorithm
Each incoming signal receives a progressively richer execution context.
Pseudo workflow:
ResolveIdentity()
ResolveSchemas()
ResolveOrganization()
ResolveLineage()
ResolveReplay()
ResolveGovernance()
ResolveFederation()
ResolveAI()
ResolveRisk()
MergeContexts()
ValidateContext()
Publish()
Every stage either:
- enriches the signal
- produces an explainable warning
- aborts processing
depending upon configured policy.
12. Runtime Algorithm
function enrich(signal):
identity = IdentityResolver.resolve(signal.eco_number)
schemas = SchemaResolver.load(signal.metric_type)
organization = OrganizationResolver.load(identity)
lineage = LineageResolver.resolve(signal)
governance = GovernanceResolver.load(identity)
replay = ReplayResolver.lookup(signal)
federation = FederationResolver.lookup(identity)
ai = AIResolver.recommend(signal)
risk = RiskResolver.evaluate(signal)
context = MergeContext(
signal,
identity,
organization,
schemas,
lineage,
governance,
replay,
federation,
ai,
risk
)
Validate(context)
return context
The algorithm must remain deterministic.
Identical inputs shall always produce identical enrichment outputs.
13. Identity Resolution
Identity resolution is always executed first.
Inputs include:
- ECO Number
- DID
- Controller URI
- Federation Node
- Organization Identifier
The engine retrieves:
| Property | Source |
|---|---|
| ECO metadata | ZAR |
| DID Document | EGFS |
| Federation Node | EGFS Registry |
| Organization status | FAGF |
| Trust profile | AII |
Failure to resolve identity immediately terminates enrichment.
14. Organization Context Resolution
Once identity has been established, organizational metadata is attached.
Retrieved information includes:
| Metadata | Source |
|---|---|
| Organization type | ZAR |
| Industry | NACE Registry |
| Country | Country Registry |
| Federation Region | EGFS |
| Assurance Tier | FAGF |
| Regulatory Scope | Governance Registry |
| Tenant configuration | ZAR |
Example:
{
"organization": {
"eco_number": "ECO-A123",
"type": "Enterprise",
"region": "EU",
"nace":"C25.11",
"assurance_tier":"Tier-2"
}
}
15. Schema Resolution
The engine resolves the canonical schema required for the incoming signal.
Primary source:
SSSR
Lookup sequence:
Metric Type
↓
Schema Registry
↓
Latest Approved Schema
↓
Version Compatibility
↓
Schema Cache
↓
Runtime Attachment
Returned metadata includes:
- CSI
- schema version
- validation profile
- semantic mappings
- ontology references
16. Lineage Resolution
Operational lineage is retrieved from USO.
Additional verification anchors are retrieved from DAL.
Information attached includes:
| Item | Source |
|---|---|
| Event lineage | USO |
| Processing history | USO |
| Replay references | AAE |
| DAL anchors | DAL |
| Verification proofs | DAL |
Example:
{
"lineage": {
"uso_id":"USO-9981",
"dal_anchor":"DAL-782991",
"parent_events":18,
"verified":true
}
}
17. Governance Resolution
Applicable governance rules are loaded dynamically.
Sources:
- FAGF
- OARM
- Policy Registry
Retrieved:
- active policy bundle
- regulatory profile
- organization overrides
- reviewer requirements
- trust thresholds
The engine never embeds governance logic.
It only retrieves active policies.
18. Replay Context Resolution
Historical replay information is retrieved from AAE.
Information includes:
| Field | Description |
|---|---|
| replay_count | Previous replay executions |
| replay_success | Replay verification rate |
| replay_variance | Historical drift |
| confidence | Replay confidence |
| last_replay | Timestamp |
Replay information contributes to downstream trust scoring.
19. Federation Context Resolution
Federation metadata is retrieved through EGFS.
Attached metadata includes:
- federation node
- regional trust profile
- synchronization status
- node health
- certificate chain
- policy version
Example:
{
"federation":{
"region":"EU",
"node":"EU-3",
"status":"healthy",
"sync_state":"current"
}
}
20. AI Context Resolution
Context recommendations are requested from DSAIL.
Returned recommendations are advisory.
Examples:
{
"ai":{
"risk_score":0.19,
"confidence":0.94,
"recommendation":"Increase replay frequency"
}
}
The engine never allows AI to modify facts.
AI only augments context.
21. Risk Context Resolution
Risk metadata originates from:
- RIF
- DSAIL
- TrustGate history
Attached metadata includes:
- entity risk
- supplier risk
- geopolitical risk
- anomaly score
- fraud indicators
Risk information is later consumed by Trust Scoring.
22. Context Merge Strategy
After every enrichment stage completes successfully, all context objects are merged.
Merge priority:
Incoming Signal
↓
Identity
↓
Organization
↓
Schema
↓
Lineage
↓
Governance
↓
Replay
↓
Federation
↓
AI
↓
Risk
Conflicts are never silently overwritten.
Conflicts produce explicit enrichment events.
23. Context Completeness Score
The engine computes an internal completeness indicator.
This metric is not a trust score.
It measures enrichment completeness.
The score is calculated as:
Required objects include:
- identity
- schema
- organization
- governance
- lineage
Optional objects include:
- AI
- federation
- replay
- risk
This metric supports operational monitoring but is never exposed as a public TrustGate score.
24. Failure Handling
Each enrichment stage defines a severity level.
| Failure | Action |
|---|---|
| Missing identity | Abort |
| Missing schema | Abort |
| Missing lineage | Warning |
| Missing replay | Continue |
| Missing federation | Continue |
| Missing AI | Continue |
| Missing governance | Abort |
Failures produce immutable enrichment events recorded within USO.
25. Runtime Characteristics
| Characteristic | Target |
|---|---|
| Average latency | < 60 ms |
| P95 latency | < 150 ms |
| Maximum external lookups | 10 |
| Maximum retries | 3 |
| Cache TTL | 10 minutes |
| Parallel lookup support | Yes |
| Replay deterministic | Yes |
| Stateless execution | Yes |
The engine is designed for horizontal scaling and may execute concurrently across multiple TrustGate worker instances while maintaining deterministic outputs.
26. Canonical Input Schema
The Context Enrichment Engine accepts only normalized TrustGate runtime objects.
The input shall already have successfully completed:
- Signal Parsing
- Signal Normalization
No schema validation beyond structural verification is performed prior to enrichment.
Example:
{
"signal_id": "SIG-2026-00001472",
"eco_number": "ECO-A123",
"metric_type": "energy.total_consumption",
"metric_value": 12843.2,
"unit": "kWh",
"period": "2026-Q1",
"source_system": "SAP-S4",
"received_at": "2026-06-25T10:41:13Z",
"normalization_version": "1.0.0"
}
27. Canonical Enriched Output
After enrichment the signal becomes the canonical TrustGate runtime object.
Example:
{
"signal_id": "SIG-2026-00001472",
"identity": {
"eco_number": "ECO-A123",
"did": "did:zayaz:ECO-A123",
"organization_type": "Enterprise"
},
"metric": {
"metric_type": "energy.total_consumption",
"metric_value": 12843.2,
"unit": "kWh",
"period": "2026-Q1"
},
"organization": {
"nace": "C25.11",
"country": "DK",
"assurance_tier": "Tier-2"
},
"schema": {
"csi": "comp.AIIL.INPUT.TRUST-SCORE.1_0",
"version": "1.2.0"
},
"lineage": {
"uso_id": "USO-98122",
"dal_anchor": "DAL-991223",
"verified": true
},
"governance": {
"policy_bundle": "FAGF-2026.2"
},
"replay": {
"confidence": 0.96,
"replay_count": 7
},
"federation": {
"region": "EU",
"node": "EU-3"
},
"ai": {
"confidence": 0.93,
"recommendation": "Increase replay frequency"
}
}
28. Context Object Model
The engine produces nine logical context objects.
| Context Object | Mandatory | Source |
|---|---|---|
| Identity | ✓ | EGFS / ZAR |
| Organization | ✓ | ZAR |
| Schema | ✓ | SSSR |
| Lineage | ✓ | USO + DAL |
| Governance | ✓ | FAGF |
| Replay | Optional | AAE |
| Federation | Optional | EGFS |
| AI | Optional | DSAIL |
| Risk | Optional | RIF |
Mandatory objects are required for successful completion.
29. Runtime Lookup Matrix
The engine performs several independent lookups.
| Lookup | Primary Source | Secondary Source | Cache |
|---|---|---|---|
| Identity | EGFS Registry | ZAR | Yes |
| Organization | ZAR | USO | Yes |
| Schema | SSSR | Cache | Yes |
| Lineage | USO | DAL | No |
| Governance | FAGF | OARM | Yes |
| Replay | AAE | DAL | No |
| Federation | EGFS | Registry Cache | Yes |
| AI | DSAIL | — | No |
| Risk | RIF | DSAIL | No |
Lookups may execute in parallel where dependencies permit.
30. CSI Contracts
The engine consumes and produces canonical CSIs.
Input CSIs
| CSI | Purpose |
|---|---|
| comp.TG.INPUT.NORMALIZED-SIGNAL.1_0 | Canonical normalized TrustGate signal |
| comp.USO.LINEAGE.EVENT.1_0 | Operational lineage |
| comp.DAL.ANCHOR.PROOF.1_0 | Ledger verification |
| comp.SSSR.SCHEMA.REGISTRY.1_0 | Schema metadata |
Output CSIs
| CSI | Purpose |
|---|---|
| comp.TG.OUTPUT.ENRICHED-SIGNAL.1_0 | Canonical enriched TrustGate signal |
| comp.TG.EVENT.ENRICHMENT.1_0 | Enrichment audit event |
| comp.TG.EVENT.CONTEXT-COMPLETE.1_0 | Context completeness event |
31. CMI Registration
The engine is registered in ZAR.
| Property | Value |
|---|---|
| CMI | vera.TG-ENRICH.ENGINE.CONTEXT.1_0_0 |
| MEID | MEID_SIGNAL_ENRICH_CONTEXT |
| Engine Type | ENRICH |
| Runtime | TrustGate |
| Registry | ZAR |
32. Context Merge Rules
Context merging follows deterministic precedence.
| Priority | Context |
|---|---|
| 1 | Incoming Signal |
| 2 | Identity |
| 3 | Organization |
| 4 | Schema |
| 5 | Lineage |
| 6 | Governance |
| 7 | Replay |
| 8 | Federation |
| 9 | AI |
| 10 | Risk |
No downstream context may overwrite upstream facts.
Conflicting values generate explicit enrichment conflict events.
33. Enrichment Event Model
Every enrichment stage emits immutable events.
Example:
{
"event_type": "context_enriched",
"signal_id": "SIG-2026-00001472",
"stage": "Governance",
"status": "success",
"duration_ms": 14,
"source": "FAGF",
"timestamp": "2026-06-25T10:41:15Z"
}
Events become part of the USO operational history.
34. Context Completeness Event
After merging, the engine emits a completeness summary.
Example:
{
"signal_id": "SIG-2026-00001472",
"resolved_objects": 9,
"required_objects": 9,
"optional_objects": 3,
"context_completeness": 1.00,
"status": "complete"
}
The Context Completeness metric is an operational KPI and shall never be interpreted as a trust score.

36. Engine Metrics
The engine publishes operational metrics to VIZZ and the Assurance Analytics Engine (AAE).
| Metric | Description |
|---|---|
| Enrichment Throughput | Signals processed per second |
| Lookup Latency | Average lookup time by dependency |
| Cache Hit Rate | Percentage of cache hits |
| Context Completeness | Average completeness ratio |
| Lookup Failures | Failed external lookups |
| Governance Version Drift | Outdated policy bundle usage |
| Federation Availability | Federation lookup success |
| Average Processing Time | End-to-end execution latency |
These metrics provide operational visibility and feed capacity planning, anomaly detection, and runtime optimization dashboards.
37. Replay Integration
The Context Enrichment Engine is fully replay-aware and participates in the TrustGate replay framework coordinated by the Autonomous Assurance Engine (AAE).
The engine does not perform replay verification itself but enriches signals with replay metadata that downstream engines use during trust scoring, assurance, and certification.
Replay Inputs
| Source | Purpose |
|---|---|
| AAE | Replay history |
| DAL | Previous ledger anchors |
| USO | Historical execution lineage |
| TrustGate | Previous trust decisions |
Replay Metadata
Example:
{
"replay": {
"replay_id": "RPL-2026-000842",
"replay_count": 7,
"last_replay_at": "2026-06-21T14:22:10Z",
"verification_rate": 0.986,
"confidence": 0.97,
"variance": 0.011,
"verified": true
}
}
Replay Resolution Strategy
The replay subsystem follows this lookup order:
Signal
↓
USO Lineage
↓
AAE Replay Registry
↓
DAL Anchors
↓
Historical Trust Scores
↓
Replay Context
Replay data is immutable.
Historical replay records are never modified.
38. Federation Integration
The engine operates transparently across the entire ZAYAZ Federation.
Identity and federation metadata are resolved through EGFS.
The engine is federation-neutral.
It does not distinguish between:
- organizations
- suppliers
- regulators
- auditors
- governments
Every participant is represented by an ECO Number and a DID.
Federation Services Used
| Service | Purpose |
|---|---|
| Federation Registry | Resolve organization |
| DID Registry | Resolve identity |
| Policy Distribution | Retrieve governance |
| Federation Health | Node availability |
| Federation Routing | Cross-region routing |
Federation Context Example
{
"federation": {
"eco_number": "ECO-A123",
"did": "did:zayaz:ECO-A123",
"region": "EU",
"node": "EU-3",
"policy_version": "FAGF-2026.2",
"sync_state": "current",
"certificate_status": "valid"
}
}
39. AI Integration
The Context Enrichment Engine interacts with DSAIL exclusively through advisory interfaces.
Artificial Intelligence never modifies factual signal data.
AI may only recommend:
- replay priorities
- anomaly indicators
- enrichment recommendations
- confidence estimates
- risk indicators
All recommendations are stored separately from factual metadata.
AI Recommendation Example
{
"ai": {
"model": "vera.DSAIL.MODEL.CONTEXT.2_0_0",
"confidence": 0.95,
"recommendation": "Increase replay frequency",
"reason": "Higher than expected variance",
"explainability_score": 0.93
}
}
AI Safety Rules
The engine enforces the following principles:
| Rule | Description |
|---|---|
| AI cannot overwrite facts | Mandatory |
| AI recommendations are explainable | Mandatory |
| AI confidence must be recorded | Mandatory |
| Human override supported | Mandatory |
| AI model version recorded | Mandatory |
| Recommendation provenance retained | Mandatory |
All AI outputs become lineage events within USO.
40. DAL Integration
The engine enriches signals with Distributed Assurance Ledger (DAL) references.
No new anchors are created.
Instead, the engine resolves:
- previous anchors
- parent anchors
- verification proofs
- replay anchors
Example:
{
"dal": {
"anchor_id": "DAL-991223",
"parent_anchor": "DAL-991120",
"verification_status": "verified",
"proof_hash": "b97dca62..."
}
}
41. USO Integration
The Universal Sustainability Object (USO) provides the operational lineage required for enrichment.
Retrieved metadata includes:
| Metadata | Description |
|---|---|
| Event history | Complete execution chain |
| Parent object | Previous operational object |
| Processing stage | Current lifecycle stage |
| Lineage depth | Number of ancestors |
| Replay references | Historical replay events |
USO provides the canonical operational history.
42. Security Model
The Context Enrichment Engine processes trusted internal runtime data only.
External requests must pass TrustGate authentication before enrichment.
Authentication
Supported mechanisms:
- OAuth2
- Mutual TLS
- Federation certificates
- JWT
- API Keys (internal)
Authorization
Authorization is evaluated using:
- ECO identity
- Federation role
- Organization permissions
- Runtime policy bundle
Encryption
| Layer | Standard |
|---|---|
| Transport | TLS 1.3 |
| Internal gRPC | mTLS |
| Stored secrets | AWS KMS |
| DAL Anchors | SHA-256 + Ed25519 |
| AI Models | Signed ZAR packages |
43. Audit Logging
Every enrichment stage generates immutable audit records.
Example:
{
"event_type": "context_lookup",
"resolver": "SchemaResolver",
"source": "SSSR",
"duration_ms": 18,
"status": "success",
"timestamp": "2026-06-25T10:42:19Z"
}
Audit events become part of the operational lineage.
44. Observability
Operational metrics are exported to:
- VIZZ
- AAE
- TrustGate Dashboard
- CloudWatch
- Prometheus
Runtime Metrics
| Metric | Description |
|---|---|
| Signals/sec | Processing throughput |
| Lookup latency | External dependency latency |
| Cache hit ratio | Cache efficiency |
| Replay lookup latency | Replay subsystem performance |
| Context completeness | Average completeness score |
| Federation lookup latency | EGFS performance |
| DAL lookup latency | Ledger access time |
| Failure rate | Processing failures |
45. Health Checks
The engine exposes runtime health endpoints.
| Endpoint | Purpose |
|---|---|
/health | Liveness |
/ready | Readiness |
/metrics | Prometheus metrics |
/version | Runtime version |
/status | Dependency status |
46. Deployment Model
The Context Enrichment Engine is stateless.
Multiple instances may execute concurrently.
Deployment targets include:
- Kubernetes
- ECS
- EKS
- Local development
- Integration test environments
Caching is externalized.
No runtime state is stored locally.
47. Failure Recovery
The engine supports graceful degradation.
| Dependency | Behaviour |
|---|---|
| SSSR unavailable | Retry → Fail |
| ZAR unavailable | Retry → Fail |
| EGFS unavailable | Cached lookup |
| AAE unavailable | Continue without replay |
| DSAIL unavailable | Continue without AI |
| RIF unavailable | Continue without risk |
| DAL unavailable | Retry → Cached proof |
Only failures affecting mandatory context objects terminate processing.
48. Compliance
The Context Enrichment Engine contributes to compliance with:
| Framework | Purpose |
|---|---|
| CSRD | Sustainability reporting |
| ESRS | ESG disclosures |
| ISSB | Sustainability disclosures |
| IFRS S1 | Governance |
| IFRS S2 | Climate disclosures |
| ISO 27001 | Information security |
| ISO 14064-1 | GHG assurance |

50. Summary
The TrustGate Context Enrichment Engine transforms normalized runtime signals into fully contextualized operational objects by attaching identity, governance, schema, lineage, replay, federation, AI, and risk metadata.
The engine serves as the canonical enrichment layer within the TrustGate runtime pipeline and ensures that all downstream trust scoring, verification, assurance, replay, federation synchronization, and audit processes operate on semantically complete, cryptographically traceable, and governance-aware data.
