feat(ultraplan-local): v1.6.0 — /ultraresearch-local deep research command

Add /ultraresearch-local for structured research combining local codebase
analysis with external knowledge via parallel agent swarms. Produces research
briefs with triangulation, confidence ratings, and source quality assessment.

New command: /ultraresearch-local with modes --quick, --local, --external, --fg.
New agents: research-orchestrator (opus), docs-researcher, community-researcher,
security-researcher, contrarian-researcher, gemini-bridge (all sonnet).
New template: research-brief-template.md.

Integration: --research flag in /ultraplan-local accepts pre-built research
briefs (up to 3), enriches the interview and exploration phases. Planning
orchestrator cross-references brief findings during synthesis.

Design principle: Context Engineering — right information to right agent at
right time. Research briefs are structured artifacts in the pipeline:
ultraresearch → brief → ultraplan --research → plan → ultraexecute.

+# AI Threat Modeling Using STRIDE Framework
+
+**Last updated:** 2026-02
+**Status:** Established Practice
+**Category:** AI Security Engineering
+
+---
+
+## Introduksjon
+
+Trusselmodellering for AI-systemer krever en tilpasning av etablerte sikkerhetsprinsipper til nye angrepsflater som er spesifikke for maskinlæring og generativ AI. Microsoft har utvidet det klassiske STRIDE-rammeverket (Spoofing, Tampering, Repudiation, Information Disclosure, Denial of Service, Elevation of Privilege) til å dekke AI-spesifikke trusler som datapoisoning, adversarial attacks, model inversion og prompt injection.
+
+STRIDE for AI bygger på Microsoft Security Development Lifecycle (SDL), men introduserer nye dimensjoner: behandling av treningsdata som trust boundaries, vurdering av modellens output-integritet, og kartlegging av dependencies i ML supply chain. Rammeverket sikrer at både data scientists og security engineers kan ha strukturerte samtaler om AI-risiko uten å kreve dyp ekspertise i hverandres felt.
+
+I norsk offentlig sektor er strukturert trusselmodellering et krav for AI-systemer som behandler personopplysninger eller støtter kritiske beslutningsprosesser. NSMs grunnprinsipper for IKT-sikkerhet må suppleres med AI-spesifikke sikkerhetskrav, og STRIDE-basert trusselmodellering gir et systematisk grunnlag for ROS-analyse og sikkerhetskontroller.
+
+## Kjernekomponenter
+
+### STRIDE Adaptation for AI Systems
+
+| STRIDE Category | AI-Specific Threat | Severity | Mitigation Focus |
+|-----------------|-------------------|----------|------------------|
+| **Spoofing** | Neural Net Reprogramming, Malicious ML Providers | Important-Critical | Strong API authentication, access control, client-server mutual auth |
+| **Tampering** | Data Poisoning (targeted/indiscriminate), Backdoored Models | Critical | Training data validation, anomaly detection, RONI defense, bagging |
+| **Repudiation** | Model output manipulation, training data lineage loss | Moderate | Logging, audit trails, data provenance tracking |
+| **Information Disclosure** | Model Inversion, Membership Inference, Model Stealing | Important-Critical | Rate limiting, access control, output obfuscation, differential privacy |
+| **Denial of Service** | Confidence Reduction, Random Misclassification | Important | Adversarial training, feature denoising, input validation |
+| **Elevation of Privilege** | Adversarial Perturbation, Excessive Agency, Physical Domain Attacks | Critical | Adversarial robustness, least privilege on plugins, input sanitization |
+
+### Trust Boundary Shifts in AI
+
+Tradisjonell trusselmodellering fokuserer på nettverksgrenser og applikasjonsgrenser. I AI-systemer må trust boundaries utvides til:
+
+1. **Training Data Stores** — behandles som potensielt kompromitterte kilder (garbage-in/garbage-out)
+2. **ML Supply Chain** — pre-trained models, model zoos, data providers, MLaaS-leverandører
+3. **Model APIs** — query-access kan misbrukes til model extraction, inversion, membership inference
+4. **Plugin/Extension Layer** — LLM-agents som kaller eksterne verktøy introduserer nye EOP-vektorer
+5. **Physical Domain** — AI-beslutninger kan manifestere seg fysisk (autonomous vehicles, robotics)
+
+### Key Questions in AI Security Reviews
+
+**Data Integrity:**
+- Hvis treningsdata er kompromittert, hvordan oppdages det?
+- Brukes user-supplied inputs i trening? Hvilken validering gjøres?
+- Kan modellen outputte sensitive data den ble trent på?
+- Hva er lineage og provenance for treningsdata?
+
+**Model Security:**
+- Kan modellen kopieres/stjeles gjennom API-queries?
+- Kan membership inference avsløre om spesifikke personer er i treningsdatasettet?
+- Returnerer modellen raw confidence scores som kan misbrukes?
+- Kan adversarial examples tvinge misklassifisering?
+
+**Supply Chain:**
+- Hvilke third-party models eller data providers brukes?
+- Er pre-trained models verifisert for backdoors eller poisoning?
+- Kan 3rd-party kunder bygge facade over API-et for skadelig bruk?
+
+**Impact Assessment:**
+- Kan modellen brukes til å forårsake fysisk skade (self-driving cars, medical diagnosis)?
+- Hva er konsekvensen av false positives vs false negatives?
+- Kan output brukes til trolling, bias amplification eller reputational damage?
+
+## Arkitekturmønstre
+
+### Pattern 1: Defense in Depth for Training Pipeline
+
+**Scenario:** Organisasjon trener egne modeller på curated datasets kombinert med public data.
+
+**Threat Model Approach:**
+1. **Data Ingestion Boundary** — validate, sanitize, log all external data sources; implement anomaly detection on data distribution
+2. **Training Environment Isolation** — segregate training from production; use private endpoints, managed identities
+3. **Model Validation Gateway** — test for adversarial robustness, bias, performance drift before deployment
+4. **Monitoring Layer** — track confidence scores, classification accuracy, data lineage changes
+
+**Fordeler:**
+- Reduserer risiko for data poisoning ved å isolere hver fase
+- Gir audit trail for ROS-analyse og incident response
+- Tillater rollback til tidligere modellversjoner ved kompromittering
+
+**Ulemper:**
+- Økt kompleksitet og kostnader
+- Krever dedikert security competence i data science team
+
+---
+
+### Pattern 2: Zero Trust for Model APIs
+
+**Scenario:** Eksponering av ML-modell som API for interne eller eksterne consumers.
+
+**Threat Model Approach:**
+1. **Authentication** — Entra ID managed identities, no stored credentials
+2. **Authorization** — RBAC with least privilege; rate limiting per caller
+3. **Input Validation** — define well-formed queries; reject malformed/adversarial inputs
+4. **Output Sanitization** — round confidence scores; redact sensitive data patterns; apply content filtering
+5. **Monitoring** — detect high-frequency queries (model stealing), anomalous inputs (adversarial examples)
+
+**Fordeler:**
+- Beskytter mot model extraction og inversion attacks
+- Gir telemetry for sikkerhetshendelser
+- Enklere å implementere compliance-kontroller (DLP, logging)
+
+**Ulemper:**
+- Rate limiting kan påvirke legitime bruksscenarioer
+- Output obfuscation kan redusere nytteverdi for consumers
+
+---
+
+### Pattern 3: Threat Modeling for Agentic AI (LLM with Plugins)
+
+**Scenario:** Copilot Studio agent med custom plugins som kan utføre actions (e.g., send email, update database).
+
+**Threat Model Approach:**
+1. **Identify Trust Boundaries** — user prompt → orchestrator → LLM → plugin → external service
+2. **Apply STRIDE per Boundary:**
+   - **User Prompt (I)** — Prompt Injection, Jailbreaking (Elevation of Privilege)
+   - **Orchestrator (T)** — Intent Detection Manipulation (Tampering)
+   - **LLM Output (I)** — Insecure Output Handling, Hallucinations (Information Disclosure)
+   - **Plugin Layer (E)** — Excessive Agency, Unauthorized Actions (Elevation of Privilege)
+   - **External Service (S)** — Credential Leakage, Data Exfiltration (Spoofing/Information Disclosure)
+3. **Mitigation Controls:**
+   - Prompt Shields (Azure AI Content Safety)
+   - Least privilege for plugins (minimal scope, approval workflows)
+   - Output validation and sanitization before plugin execution
+   - Logging and monitoring of all plugin actions
+
+**Fordeler:**
+- Systematisk kartlegging av alle angrepsflater i kompleks agent-arkitektur
+- Enklere å kommunisere risiko til non-technical stakeholders
+- Grunnlag for DPIA og sikkerhetsdokumentasjon
+
+**Ulemper:**
+- Krever dyp forståelse av både LLM-sikkerhet og plugin-arkitektur
+- Mitigations kan begrense agent-funksjonalitet (user experience trade-offs)
+
+## Beslutningsveiledning
+
+### Når Bruke STRIDE vs. MITRE ATLAS vs. OWASP Top 10 for LLM
+
+| Framework | Best Fit | Key Advantage | Limitations |
+|-----------|----------|---------------|-------------|
+| **STRIDE (AI-adapted)** | Traditional ML systems, model APIs, training pipelines | Established SDL integration, broad security coverage | Mindre granularitet for LLM-specific threats (prompt injection) |
+| **MITRE ATLAS** | Deep threat intelligence, red team exercises, adversarial ML focus | Comprehensive adversarial tactics, real-world attack examples | Mer teknisk, vanskelig for non-security stakeholders |
+| **OWASP Top 10 for LLM** | Generative AI applications, chatbots, RAG systems | LLM-specific (prompt injection, insecure output, over-reliance) | Mindre coverage for traditional ML threats |
+
+**Anbefaling:** Bruk STRIDE som baseline framework, supplement med MITRE ATLAS for adversarial scenarios og OWASP Top 10 for LLM-components.
+
+### Common Mistakes in AI Threat Modeling
+
+| Mistake | Impact | Correction |
+|---------|--------|------------|
+| **Treating training data as trusted** | Data poisoning går uoppdaget; modell kompromitteres permanent | Implement data provenance tracking, anomaly detection, input validation |
+| **Ignoring model extraction risk** | Intellectual property loss; adversarial attacks developed offline | Apply rate limiting, output obfuscation, access control on model APIs |
+| **No monitoring for adversarial inputs** | Persistent misclassification attacks | Deploy adversarial detection (feature squeezing, confidence analysis) |
+| **Over-scoping plugin permissions** | LLM agent kan utføre unauthorized actions | Least privilege per plugin; require user approval for sensitive actions |
+| **Missing physical domain impact assessment** | Safety-critical systems kompromittert (autonomous vehicles, medical AI) | Include physical harm scenarios in threat model; higher severity bar |
+
+### Red Flags in AI Architecture Review
+
+- [ ] Modellen trenes på public/uncurated data uten validering
+- [ ] API returnerer raw confidence scores med høy presisjon
+- [ ] Ingen rate limiting eller access control på model endpoints
+- [ ] Plugin-layer har read/write til sensitive datastores uten approval workflow
+- [ ] Training environment er ikke isolert fra production
+- [ ] Ingen logging av model queries eller plugin actions
+- [ ] Pre-trained models brukes uten source verification
+- [ ] RAG-system tillater retrieval av data utenfor user's access scope

+
+## For arkitekten (Cosmo)
+
+### 8 Spørsmål å Stille i Arkitekturdialog
+
+1. **Trust Boundaries:** "Hvor er trust boundaries i deres AI-arkitektur? Behandles treningsdata som potensielt kompromittert kilde?"
+   - *Hvorfor:* Etablerer scope for trusselmodellering; unngår blind trust på data providers.
+
+2. **Model Exposure:** "Hvordan eksponeres modellen? API, embedded i app, on-device? Hvem har query-access?"
+   - *Hvorfor:* Model APIs er primær angrepsfelt for extraction, inversion, adversarial attacks.
+
+3. **Supply Chain Dependencies:** "Brukes pre-trained models eller third-party data? Hvordan verifiseres integritet?"
+   - *Hvorfor:* Backdoored models og data poisoning er Critical-severity trusler.
+
+4. **Physical Domain Impact:** "Kan AI-beslutninger manifestere seg fysisk (e.g., autonomous systems, safety-critical)?"
+   - *Hvorfor:* Øker severity bar; krever mer robust adversarial defenses.
+
+5. **Sensitive Data in Training:** "Inneholder treningsdata personopplysninger eller forretningshemmeligheter? Kan disse leakes via model output?"
+   - *Hvorfor:* Information Disclosure threat; krever differential privacy eller data minimization.
+
+6. **Adversarial Robustness Testing:** "Er modellen testet mot adversarial examples? Finnes det red team plan?"
+   - *Hvorfor:* Proaktiv oppdagelse av sårbarheter før deployment.
+
+7. **Incident Response Plan:** "Hva er plan hvis modellen blir kompromittert eller data poisoning oppdages?"
+   - *Hvorfor:* AI-specific incident response (rollback, retrain, forensics) må være definert.
+
+8. **Compliance Alignment:** "Hvordan dokumenteres threat model for DPIA, ROS-analyse eller sikkerhetsgodkjenning?"
+   - *Hvorfor:* Sikrer at threat modeling leverer nødvendig dokumentasjon for offentlig sektor compliance.
+
+### Vanlige Fallgruver
+
+**Fallgruve 1: "Vi bruker Azure OpenAI, så sikkerhet er Microsofts ansvar"**
+- *Realitet:* Microsoft sikrer platform, men kunde må implementere access control, prompt injection defense, output validation, monitoring.
+- *Cosmo's respons:* "Shared responsibility model gjelder også AI. Dere må threat-modellere deres bruk av Azure OpenAI, ikke selve tjenesten."
+
+**Fallgruve 2: "Threat modeling er for traditional security, AI er annerledes"**
+- *Realitet:* STRIDE er tilpasset AI; tradisjonell sikkerhet er fortsatt viktig (exploit software dependencies er AI-trussel #11).
+- *Cosmo's respons:* "AI introduserer nye trusler, men fundamentet er det samme. STRIDE gir felles språk mellom security og data science."
+
+**Fallgruve 3: "Vi gjør threat modeling én gang ved prosjektstart"**
+- *Realitet:* AI-systemer evolverer (nye data sources, model updates, plugin additions); threat model må oppdateres.
+- *Cosmo's respons:* "Threat model er living document. Oppdater ved hver arkitekturendring, og gjenta ved nye releases."
+
+### Anbefalinger for Gjennomføring
+
+1. **Involver både security og data science** — Unngå siloer; STRIDE-workshop krever begge perspektiver.
+2. **Start med data flow diagram** — Visualiser alle komponenter, grenser, data flows før STRIDE-analyze.
+3. **Bruk threat libraries** — MITRE ATLAS og OWASP Top 10 for LLM som supplement til STRIDE; ikke start fra scratch.
+4. **Prioriter basert på severity OG feasibility** — Critical-severity trussel med lav attack complexity må fikses først.
+5. **Koble til eksisterende SDL-prosess** — Threat modeling skal ikke være isolert; integrer med code review, testing, deployment pipelines.
+6. **Dokumenter for compliance** — ROS-analyse, DPIA, sikkerhetsgodkjenning krever strukturert trusselmodell; bruk STRIDE som grunnlag.
+7. **Test mitigations** — Ikke anta at adversarial training fungerer; red team testing er nødvendig.
+8. **Oppdater threat model kontinuerlig** — Nye angrepsmetoder publiseres (MITRE ATLAS tracker real-world incidents); hold threat model current.
