Real-World UAT: Policy Source Tracking

Date: 2026-02-04 (Updated 2026-02-05) Status: PASS Focus: User journey validation, not mechanical correctness

User Stories Under Test

Story 1: Security Team → Dev Team Handoff

As a developer, when I run aphoria scan and get a BLOCK, I need to see which policy pack flagged it and who issued it, so I can discuss with the right team.

Story 2: Multi-Pack Audit

As a compliance officer, I need to understand which authoritative sources are active in a project and trace any conflict back to its origin.

Story 3: Policy Evolution

As a security lead, when I update our standards pack from v1.0 to v2.0, the attribution should update so teams know they're running against current policy.

Test Scenarios

Scenario 1: Full Round-Trip Attribution

Setup:

1. Create a test project with code that violates a policy
2. Bless a security standard
3. Export as "Security-Standards-v1.0"
4. Import into fresh project
5. Scan code
6. Verify attribution appears in ALL output formats

Success Criteria:

• JSON output includes policy_source.pack_name, pack_version, issuer_hex
• Table output shows policy source column
• Markdown output includes policy source section
• SARIF output maps policy source to appropriate fields

Scenario 2: Multi-Pack Conflict Resolution

Setup:

1. Create Pack A with assertion: tls/version = "1.2"
2. Create Pack B with assertion: tls/version = "1.3"
3. Import both packs
4. Scan code that uses TLS 1.1
5. Verify both conflicting sources shown

Success Criteria:

• Both pack sources appear in conflict report
• User can see which packs disagree
• Clear indication of conflict between policies themselves

(Deferred to future UAT - requires multi-pack import support)

Scenario 3: Pack Version Update

Setup:

1. Import "Standards-v1.0.pack"
2. Scan and note attribution
3. Import "Standards-v2.0.pack" (same subjects, updated)
4. Scan again
5. Verify attribution shows v2.0

Success Criteria:

• Version updates from 1.0 to 2.0
• Pack name remains correct
• Old version no longer appears

(Deferred to future UAT - requires pack versioning workflow)

Scenario 4: Report Format Verification

Setup:

1. Create a conflict with known policy source
2. Export in each format: json, table, markdown, sarif

Success Criteria:

• --format json: conflicts[].sources[].policy_source populated
• --format table: Policy source visible for Trust Pack assertions
• --format markdown: Policy source in conflict details
• --format sarif: Valid SARIF structure with conflict details

Automated Test Script

The end-to-end workflow is validated by:

applications/aphoria/uat/scripts/test-enterprise-workflow.sh

This script:

1. Creates a security team project with blessed standards
2. Exports a Trust Pack
3. Creates a dev team project with TLS violations (YAML patterns)
4. Imports the Trust Pack
5. Scans and verifies conflicts are found with policy source attribution
6. Tests all output formats (JSON, table, markdown, SARIF)

Technical Details

How It Works

1. Security team blesses standards:

   aphoria bless "code://standard/tls/cert_verification" \
       --predicate enabled --value true \
       --reason "Certificate verification required"
   

2. Export creates Trust Pack:

   • Collects blessed assertions from predicate index
   • Signs with Ed25519 key
   • Packages as .pack file

3. Dev team imports pack:

   • Verifies signature
   • Stores assertions via WAL
   • Records pack source in PackSourceStore

4. Scan detects conflicts:

   • fetch_authoritative_assertions() loads imported Trust Pack assertions
   • ConceptIndex includes both bundled (RFC/OWASP) and imported assertions
   • Tail-path matching: tls/cert_verification::enabled connects code → standard
   • Policy source retrieved from PackSourceStore during conflict building

Key Files

File	Purpose
scan.rs	Includes imported assertions in ConceptIndex
policy_ops.rs	Import/export Trust Pack operations
local.rs	fetch_authoritative_assertions() + pack_source lookup
pack_source_store.rs	Store/retrieve policy attribution
concept_index.rs	Tail-path key matching

Tail-Path Matching

The key insight is how concept paths match:

Code Pattern	Matches Standard
code://config/my-service/config/tls/tls/cert_verification	code://standard/tls/cert_verification
code://rust/myapp/grpc/client/tls/min_version	code://standard/tls/min_version

Matching key: {tail_seg1}/{tail_seg2}::{predicate}

• Code: tls/cert_verification::enabled
• Standard: tls/cert_verification::enabled
• Match!

Conclusion

PASS - Real-world UAT validates the complete Trust Pack workflow:

1. Security teams can bless authoritative patterns
2. Standards can be exported as Trust Packs
3. Dev teams can import policies with one command
4. Scans detect conflicts between code and policy
5. Conflicts show full policy source attribution

The enterprise readiness deliverables are complete and ready for pilot deployments.
