Core GOAP Methodology (Enhanced)

Phase 1: State Assessment with Trust Initialization

Define Current State:

• Existing knowledge about the topic
• Available sources and access constraints
• NEW: Trusted issuer whitelist configuration
• NEW: Ed25519 keypair availability
• Time and depth requirements

Define Goal State:

• Specific questions to answer
• Required evidence types
• NEW: Minimum verification threshold (0.85 default, 0.95 strict)
• NEW: Required signature chain depth
• Confidence thresholds for conclusions

Gap Analysis:

• Knowledge gaps to fill
• NEW: Unsigned claims requiring verification
• NEW: Citation chain breaks to resolve

Phase 2: Action Inventory (Extended)

Research actions with Ed25519 verification extensions:

| Action | Preconditions | Effects | Cost | Verification | |--------|---------------|---------|------|--------------| | web_search_broad | topic_defined | candidates_found | 1 | None | | web_search_verified | topic_defined, trusted_issuers_set | verified_candidates_found | 2 | Domain signature | | fetch_source | url_known | content_retrieved | 2 | TLS certificate | | fetch_signed_source | url_known, issuer_pubkey | signed_content_retrieved | 3 | Ed25519 signature | | extract_facts | content_retrieved | facts_cataloged | 1 | None | | sign_extracted_facts | facts_cataloged, private_key | signed_facts | 2 | Self-signature | | verify_claim | claim_identified | claim_verified/refuted | 3 | Cross-ref | | verify_claim_cryptographic | claim_identified, signature_available | cryptographically_verified | 4 | Ed25519 verify | | cross_reference | multiple_sources | consistency_checked | 2 | None | | cross_reference_signed | multiple_signed_sources | signed_consistency_checked | 3 | Multi-sig verify | | build_citation_chain | facts_cataloged | citation_chain_complete | 2 | Chain integrity | | verify_citation_chain | citation_chain_complete | chain_verified | 3 | Ed25519 chain | | generate_signed_report | conclusions_formed, private_key | signed_report_delivered | 3 | Report signature |

Phase 3: Plan Generation (A* with Verification Cost)

Enhanced cost function:

f(n) = g(n) + h(n) + v(n)

• g(n): Actual cost (searches performed, time spent)
• h(n): Heuristic distance to goal (remaining questions)
• v(n): Verification penalty (unsigned claims × 0.5)

Planning Heuristics:

1. Prioritize signed sources over unsigned (lower total cost)
2. Prefer sources from trusted issuers whitelist
3. Weight cryptographically verified claims higher
4. Factor citation chain depth in confidence

Phase 4: OODA Loop with Verification Checkpoints

Observe:

• Monitor search results quality
• Track signature validity status
• Monitor citation chain integrity
• Identify information gaps

Orient:

• Assess if current path leads to goal
• Evaluate cryptographic trust level
• Check for signature chain breaks
• Recognize when verification fails

Decide:

• Continue current research branch or pivot
• Accept or reject unsigned sources
• Trigger re-verification on suspicious content
• Choose between depth and breadth

Act:

• Execute next optimal action
• Sign verified findings
• Update verification ledger
• Trigger replanning if deviation detected

Phase 5: Dynamic Replanning with Trust Recalculation

Trigger replanning when:

• Key assumption invalidated
• Signature verification fails
• Trusted issuer removed from whitelist
• Citation chain broken
• Higher-quality signed source discovered

Ed25519 Verification Protocol

Trusted Issuers Whitelist

Default trusted issuers (Level 5 sources):

trusted_issuers:
  news:
    - reuters.com
    - ap.org
    - bbc.com
  academic:
    - arxiv.org
    - nature.com
    - science.org
    - pubmed.gov
  government:
    - .gov domains
    - .gov.uk domains
    - europa.eu
  financial:
    - sec.gov
    - federalreserve.gov
    - ecb.europa.eu

Signature Verification Flow

1. Source provides content + signature + public_key_id
2. Fetch public key from trusted keyserver or issuer
3. Verify Ed25519 signature: verify(signature, content_hash, public_key)
4. Check issuer against trusted whitelist
5. Record verification result in ledger
6. Assign cryptographic trust score

Citation Chain Verification

Each fact in the chain must have:

{
  "claim": "The statement being made",
  "source_url": "https://...",
  "source_hash": "sha256:abc123...",
  "issuer_pubkey": "ed25519:xyz789...",
  "signature": "ed25519_sig:...",
  "timestamp": "2025-01-22T10:30:00Z",
  "parent_citation": "chain_id:previous_fact_id",
  "confidence": 0.95
}

Chain verification:

1. Verify each fact's signature individually
2. Verify chain integrity (parent hashes match)
3. Check all issuers are in trusted whitelist
4. Calculate aggregate chain confidence

Anti-Hallucination Rules

100% Citation Rule

Every factual claim MUST have a verifiable source. No exceptions.

❌ FORBIDDEN: "Studies show that X leads to Y"
✅ REQUIRED:  "A 2024 study published in Nature (DOI: 10.1038/...) found that X leads to Y"

Verification Thresholds

| Mode | Threshold | Use Case | |------|-----------|----------| | development | 0.75 | Exploratory research, brainstorming | | moderate | 0.85 | Standard research (default) | | strict | 0.95 | Legal, medical, financial research | | paranoid | 0.99 | Critical decisions, published reports |

Confidence Calculation

confidence = base_reliability × verification_multiplier × recency_factor

where:
  base_reliability = source level (1-5) / 5
  verification_multiplier = 1.0 if unsigned, 1.2 if signed, 1.5 if chain_verified
  recency_factor = 1.0 if <24h, 0.9 if <7d, 0.8 if <30d, 0.6 if older

7. build_citation_chain → citation_chain_complete
8. verify_citation_chain → chain_verified (confidence ≥0.95)

Pattern C: Competitive Analysis with Audit Trail

Goal: auditable_competitive_landscape
Actions:
1. identify_players → competitors_listed
2. configure_trusted_issuers → whitelist_active
3. FOR EACH competitor:
   - web_search_verified → verified_info_found
