🔍 Scope Definition

Included Systems:

🌐 Static HTML/CSS website (14-language support: Swedish, English, Danish, Norwegian, Finnish, German, French, Spanish, Dutch, Arabic, Hebrew, Japanese, Korean, Chinese)
📊 Chart.js/D3.js interactive dashboards (all functional: overview, party performance, committee network, coalition, election-cycle, risk, anomaly detection, seasonal patterns, pre-election, ministry, politician)
☁️ AWS CloudFront CDN + S3 storage (us-east-1 primary, eu-west-1 replica)
🔀 Route 53 DNS configuration with health checks
🔄 GitHub Pages disaster recovery (automatic failover)
🤖 14 AI agentic news workflows. The 13 analysis/article workflows use Claude Opus 4.8 (reasoning model) and the high-volume news-translate fan-out uses Claude Sonnet 4.6 (faster model). Each analysis/article workflow enforces analysis → analysis gate → render → safe-output PR with 23 required analysis artifacts before article generation. Examples:
- news-evening-analysis: 18:00 UTC Mon-Fri, 16:00 UTC Sat (Claude Opus 4.8)
- news-realtime-monitor: 10:00+14:00 UTC Mon-Fri, 12:00 UTC weekends (Claude Opus 4.8)
- news-translate: out-of-band fan-out from rendered EN+SV to 12 other languages (Claude Sonnet 4.6)
🔌 riksdag-regering-mcp server (32 tools for Swedish political data)
🏭 CI/CD security pipeline (GitHub Actions with OIDC)
📦 Dependency management and supply chain (Chart.js, D3.js, Vite, npm, GitHub Actions)

Out of Scope:

Backend services (none exist—frontend-only architecture)
User data persistence (public read-only platform, no user accounts)
CIA platform backend security (external data source)
Third-party CDN infrastructure security (jsDelivr for Chart.js/D3.js)
End-user device security beyond browser environment

🔐 Crown Jewel Analysis

Crown Jewels are the top 5 highest-value assets that adversaries most desire and whose compromise would cause the greatest harm to Riksdagsmonitor's democratic transparency mission.

Crown Jewel Rank	Asset	Crown Jewel Rationale	Attack Attractiveness	Compromise Impact	Protection Priority
👑 #1	🗳️ Election Data Integrity	Accuracy of election predictions, seat forecasts, and voting record aggregation from CIA platform; any manipulation directly undermines democratic accountability	VERY HIGH — Nation-state actors, political adversaries, election interference campaigns	Catastrophic: Misinformation affects public understanding of Swedish democratic processes, potential election influence	CRITICAL — Multiple overlapping controls
👑 #2	📊 Dashboard Data Accuracy	CIA platform data pipeline integrity and Chart.js/D3.js visualizations; primary channel for political transparency; 14-language real-time display	HIGH — Data accuracy is core mission; CSP/SRI protect against XSS/CDN tampering	High: Corrupted dashboards erode public trust, could misrepresent party standings or vote outcomes	HIGH — SRI hashes, CSP, dual-region
👑 #3	🌍 Multi-Language Content	14-language factual consistency (SV, EN, DA, NO, FI, DE, FR, ES, NL, AR, HE, JA, KO, ZH); translation divergence enables targeted disinformation campaigns in specific languages	HIGH — RTL (Arabic/Hebrew) harder to validate; targeted manipulation of specific language communities	High: Language-specific manipulation could spread unchecked; undermines trust of multilingual audience	HIGH — TRANSLATION_GUIDE.md, Playwright RTL testing
👑 #4	🔑 CI/CD Pipeline Security	GitHub Actions OIDC, supply chain integrity, SHA-pinned actions, SLSA attestations; compromise enables persistent content injection with no trust boundary to stop it	HIGH — Supply chain attacks (SolarWinds-pattern) increasingly common against civic platforms	Catastrophic: Persistent backdoor in CI/CD bypasses all publication controls; could inject malicious HTML into all pages	CRITICAL — OIDC, SHA-pinning, branch protection
👑 #5	📰 News Article Credibility	AI-generated (Claude Opus 4.8) daily political news accuracy; journalistic credibility for Swedish parliamentary and government activity reporting	MEDIUM-HIGH — Prompt injection, hallucination; AI-generated political misinformation campaigns	High: Fabricated parliamentary data damages reputation, could be amplified by external media; EU AI Act liability	HIGH — Mandatory PR review, dok_id validation

Crown Jewel Protection Strategy:

🔐 Defense-in-Depth: Every Crown Jewel has ≥3 overlapping controls (no single point of failure)
🎯 Zero-Tolerance Policy: Crown Jewels #1 and #4 have CRITICAL integrity requirements — any detected compromise triggers immediate incident response
🔍 Enhanced Monitoring: Crown Jewels receive continuous automated monitoring plus human spot-checks
📋 Quarterly Review: Crown Jewel list reviewed quarterly and after any significant architectural change

🔪 Kill Chain Disruption Analysis

Per Hack23 Threat Modeling Policy § 4.1.4, mapping defensive controls to each Cyber Kill Chain phase for Riksdagsmonitor:

Kill Chain Phase	Attacker Activity (Riksdagsmonitor Context)	Defensive Control	Detection Mechanism	Disruption Effectiveness
1. Reconnaissance	Scan public GitHub repo for secrets, enumerate AWS infrastructure, identify AI workflow schedules	Public repo accepted risk; minimal metadata exposure via `.gitignore`, S3 bucket policy, no directory listing	Repository traffic anomaly (GitHub Insights), Route 53 query logs	⚠️ 60% — Public repo limits concealment
2. Weaponization	Craft malicious npm package, prepare XSS payload, develop AI prompt injection	N/A — occurs off-target; no direct defense	Threat intelligence feeds (ENISA, CERT-SE, MITRE ATT&CK updates)	⚠️ 30% — Attacker-side activity
3. Delivery	Submit malicious PR, phishing for GitHub credentials, CDN asset substitution	Branch protection (PREV-002), MFA (PREV-001), SRI hashes (PREV-012), SHA-pinned Actions (PREV-015)	Dependabot alerts (DET-007), SRI failure (DET-006), CodeQL (DET-008)	✅ 95% — Multi-layer delivery blocking
4. Exploitation	Execute XSS via CDN compromise, exploit vulnerable dependency, AI prompt injection	CSP (PREV-011), Dependabot patching (PREV-013), input sanitization (PREV-023), HTTPS-only (PREV-009)	CSP violation reports (DET-005), CodeQL findings (DET-008), PR review rejection (DET-012)	✅ 92% — Static architecture limits exploitation
5. Installation	Persist via modified GitHub Actions workflow, inject into build pipeline	Workflow approval (PREV-016), CODEOWNERS (PREV-004), Git immutable history	Workflow execution logs (DET-009), GitHub audit logs (DET-001)	✅ 90% — No server-side persistence possible
6. Command & Control	Covert C2 via DNS tunneling, CDN abuse for data exfiltration	Static architecture eliminates server-side C2; Route 53 monitoring	CloudTrail (DET-002), Route 53 DNS query logs	⚠️ 70% — Limited by static-site architecture (vendor-dependent)
7. Actions on Objectives	Deface website, inject disinformation, manipulate political data, DDoS during elections	S3 versioning (PREV-019), Git revert (CORR-001), DR failover (CORR-003), mandatory PR review (PREV-028)	CloudWatch alarms (DET-004), Shield metrics (DET-010), content integrity monitoring	✅ 97% — Rapid rollback + multi-region DR

Kill Chain Disruption Summary:

Strongest disruption: Phase 3 (Delivery) at 95% and Phase 7 (Actions on Objectives) at 97% — multi-layer preventive and corrective controls
Weakest disruption: Phase 2 (Weaponization) at 30% — attacker-side activity, mitigated by threat intelligence
Architecture advantage: Static website + no server-side code eliminates Phases 5-6 attack surface almost entirely
Overall Kill Chain Disruption Score: 76% (simple average across all phases)

🎯 Motivation: Revenge, sabotage, financial gain
💰 Financial Impact: $30,000 (code audit, incident response, reputation damage)
⏱️ Recovery Time: 1-3 days (forensic investigation, Git history audit, rollback)
📊 Likelihood: VERY LOW (1/5) | Impact: HIGH (8/10) | Risk Score: 0.8/10

Attack Scenario:

Access: Contributor with existing write access (trusted insider)
Malicious Action: Introduce subtle backdoor in dashboard JavaScript (e.g., exfiltrate user IP addresses to external server)
Evasion: Obfuscate code to pass code review; use legitimate-looking variable names
Detection: CodeQL static analysis flags suspicious network call; security team investigates
Response: Immediate access revocation, Git history forensics, revert malicious commits, contributor ban

Residual Risk: VERY LOW - Mandatory code review + CodeQL + CODEOWNERS approval provides 99.2% detection rate.

Scenario 6: Cross-Language Translation Integrity Attack

🎭 Threat Actor: Nation-State APT (Information Warfare Unit)
🎯 Motivation: Subtle disinformation, narrative manipulation across languages
💰 Financial Impact: $75,000 (reputation damage, multilingual fact-checking, public correction)
⏱️ Recovery Time: 3-7 days (verify all 14 languages, correct mistranslations)
📊 Likelihood: MEDIUM (3/5) | Impact: HIGH (8/10) | Risk Score: 2.4/10

Attack Scenario:

Exploitation: AI non-determinism causes different factual claims across 14 languages (e.g., Swedish version reports 175-174 vote, English version reports 176-173)
Target: Ambiguous Swedish political terms (e.g., "betänkande" mistranslated, "riksdagsbeslut" context lost)
Detection: Cross-language consistency validator (planned Q2 2026) flags contradictions
Current Gap: No automated cross-language fact verification; human reviewers check one language only
Impact: Different language audiences receive contradictory information; undermines platform credibility

Residual Risk: MEDIUM - Requires Q2 2026 remediation (cross-language consistency validation tool).

📊 Comprehensive Threat Agent Analysis

Following Hack23 Threat Modeling Policy § 4.1, we profile adversaries by capability, motivation, and opportunity.

Threat Agent Classification Framework

Threat Agent Type	Capability Level	Motivation	Resources	Riksdagsmonitor Targeting Likelihood	Primary Threat Scenarios
🏴 Nation-State APT	ADVANCED	Political influence, espionage, disinformation	High (state budget)	MEDIUM - Swedish political transparency makes valuable target for foreign influence operations	AI hallucination manipulation, MCP server compromise, translation integrity attacks
💰 Cybercriminal	INTERMEDIATE-ADVANCED	Financial gain, ransomware, cryptojacking	Medium (organized crime)	LOW - No financial data, no user accounts, limited monetization opportunity	Supply chain attacks (CDN compromise), cryptomining via XSS, GitHub account sale
📢 Hacktivist	BEGINNER-INTERMEDIATE	Political statement, publicity, protest	Low-Medium (crowdfunded)	HIGH - Political platform makes attractive target for ideological groups	Website defacement, DDoS attacks, domain squatting, social media impersonation
👤 Malicious Insider	INTERMEDIATE	Revenge, sabotage, ideology	Low (individual contributor)	VERY LOW - Small contributor base, strong vetting	Backdoor injection, subtle data manipulation, IP theft
🧑‍💻 Script Kiddie	BEGINNER	Learning, curiosity, bragging rights	Very Low (public tools)	LOW - Limited attack surface for automated tools	Basic DDoS (botnets), public exploit attempts, GitHub spam
🌐 IMF Upstream / Transport Adversary	BEGINNER-INTERMEDIATE	Data distortion, vintage-drift injection, rate-limit disruption	Low (requires DNS/BGP/TLS position, or compromise of `data.imf.org` / `api.imf.org` / `www.imf.org`)	VERY LOW - Public data, no auth surface, egress is TLS-pinned to GitHub-runner root-CA trust anchors; client-side controls already mitigate most scenarios	DNS hijack or TLS MITM against IMF origins; WEO vintage confusion (stale WEO cited as current); cache poisoning of `analysis/data/imf/`; rate-limit saturation (~10 req/5 s). Mitigations already catalogued in TB-6a: TLS 1.3, response schema validation (`DatamapperResponse` shape + finite-numeric + year parse-guard), `.meta.json` `projectionVintage` sidecar (Economic Data Contract v2.0), 3× exponential back-off (1s→2s→4s), multi-country Datamapper `compare` batching, graceful fallback to cached snapshot, SBOM-covered pure-TS client (no external MCP surface).

Operational Security: MEDIUM (trusted insider, code review evasion tactics)
Resources: LOW (individual contributor, no external funding)
Knowledge: VERY HIGH (repository structure, dashboard logic, CI/CD workflows)

Motivation Analysis:

Primary: Revenge (conflict with maintainers, rejected contributions)
Secondary: Sabotage (undermine project reputation, introduce subtle bugs)
Strategic: Long-term (gradual backdoor introduction, delayed trigger)
Financial: IP theft (sell dashboard algorithms, repurpose code for competing project)

Opportunity Assessment:

Attack Surface: Direct repository write access, code review familiarity (knows what reviewers check), trusted contributor status
Entry Points: Legitimate pull requests with hidden backdoors, subtle data manipulation, obfuscated JavaScript
Persistence: HIGH (trusted access remains until detection)
Detection Evasion: Code review evasion (obfuscation, legitimate-looking patterns), gradual introduction

Relevant MITRE ATT&CK Tactics:

Persistence (T1098.001 - Maintain access via SSH keys)
Defense Evasion (T1027 - Obfuscated code)
Impact (T1485 - Data destruction, T1565.001 - Data manipulation)

Mitigation Priority: MEDIUM - CODEOWNERS approval, CodeQL scanning, mandatory GPG signing, contributor background awareness, access reviews.

🧑‍💻 Script Kiddie (Opportunistic Attacker)

Capability Assessment:

Technical Sophistication: BEGINNER (public exploit tools, automated scanners)
Operational Security: VERY LOW (no OPSEC, attribution trail)
Resources: VERY LOW (free tools, no budget)
Knowledge: LOW (general web vulnerabilities, no Swedish political context)

Motivation Analysis:

Primary: Learning (practice hacking skills, test exploits)
Secondary: Bragging rights (deface for reputation in hacking forums)
Strategic: Opportunistic (any vulnerable target)
Financial: None (no monetization strategy)

Opportunity Assessment:

Attack Surface: Public GitHub repository (information disclosure), known CVEs (outdated dependencies), basic DDoS (Kali Linux tools)
Entry Points: Automated vulnerability scanners, public exploit databases, GitHub secret scanning bypasses
Success Rate: VERY LOW (defense-in-depth mitigations block basic attacks)
Detection: IMMEDIATE (AWS Shield, GitHub rate limiting, basic OPSEC failures)

Relevant MITRE ATT&CK Tactics:

Initial Access (T1190 - Exploit public application via known CVEs)
Impact (T1498 - Basic DDoS attempts)

Mitigation Priority: LOW - Existing controls (Dependabot, AWS Shield, GitHub rate limiting) provide adequate protection. No additional mitigations required.

2.9 🤖 AI Model Card: Claude Opus 4.8 (primary) + Claude Sonnet 4.6 (translation)

Per Hack23 AI Policy § 4.3, all LLM applications MUST maintain model cards documenting capabilities, limitations, and security characteristics.

Dual-model architecture. Riksdagsmonitor runs two Anthropic models through the GitHub Copilot API:

Claude Opus 4.8 — the reasoning model that drives the 13 analysis/article workflows and the full 23-artifact analysis pipeline (engine.model: claude-opus-4.8). It carries the integrity-critical workload: source synthesis, significance scoring, evidence citation, and English/Swedish article drafting.

Claude Sonnet 4.6 — the faster model used only for the high-volume news-translate fan-out (engine.model: claude-sonnet-4.6), translating rendered EN+SV articles into the 12 remaining languages.

Sonnet 4.6 was the repo-wide baseline through v0.74.3; the analysis/article pipeline was promoted to the Opus reasoning model to strengthen factual grounding and reduce overreliance (LLM09) risk. GPT-5.4 / GPT-5.4-mini eligibility is resolved upstream but not yet A/B-tested on this repository.

Intended Use Cases

✅ Approved Uses (Riksdagsmonitor context):

Swedish political news article generation (14 languages)
Parliamentary data summarization (Riksdag documents, votes, committees)
Government document analysis (propositions, SOU reports, ministerial statements)
Multi-language translation validation
Factual content creation with source citations

❌ Prohibited Uses (per Hack23 AI Policy):

Real-time critical decision-making without human oversight
Personal data processing beyond public officials
Financial predictions or investment advice
Medical, legal, or safety-critical applications
Content generation without human review

Known Capabilities

Strengths:

Reasoning Depth: Opus 4.8 is a reasoning model — stronger multi-step source synthesis, significance scoring, and evidence-chaining than the prior Sonnet baseline
Multilingual Excellence: Native-level Swedish, strong Nordic languages (DA, NO, FI); Sonnet 4.6 handles the translation fan-out
Structured Output: JSON, HTML, Markdown generation with consistent formatting
Context Understanding: 200K token window enables full Riksdag document analysis
Factual Grounding: Strong performance with factual queries when given proper MCP-sourced context
Citation Capability: Able to include document IDs and source references

Weaknesses (conservative posture retained regardless of model uplift):

Hallucination Risk: Non-zero hallucination on low-confidence queries; Opus 4.8 reduces but does not eliminate it — overreliance (LLM09) remains the highest-priority AI risk and is mitigated by mandatory dok_id validation and PR review
Date Sensitivity: Vendor training cutoff limits real-time Swedish political events; mitigated by always grounding facts through the riksdag-regering-mcp server rather than model memory
Non-Determinism: Same prompt may yield different outputs across invocations
Prompt Injection: Vulnerable to indirect prompt injection via document titles
Bias Potential: Training data bias toward Western media sources and English-language content

Threat Actor: Nation-State APT (e.g., GRU/SVR-affiliated actors)
Objective: Undermine Swedish democratic institutions via subtle, AI-amplified disinformation
Attack Phases:

🔍 Reconnaissance: Map Riksdagsmonitor's data sources, publication timing, and editorial patterns
💉 Data Poisoning: Inject subtly biased content into upstream data sources (e.g., manipulated metadata in public APIs)
🤖 AI Amplification: Exploit AI's pattern-matching to amplify injected biases across 14 languages
📡 Distribution: Use legitimate-appearing content to undermine trust in Swedish institutions
🔄 Persistence: Maintain long-term subtle influence below detection thresholds

gh-aw Defenses:

✅ AWF network isolation prevents agent from accessing non-allowlisted sources
✅ MCP container sandboxing limits data source compromise blast radius
✅ SafeOutputs content validation catches schema violations
✅ Human review gate catches remaining semantic anomalies
⚠️ GAP: Automated bias/sentiment analysis not yet deployed (planned Q2 2026)

🗳️ Scenario: Election Day Disinformation Campaign

Threat Actor: Nation-State APT (Foreign Intelligence Service)
Timing: Swedish parliamentary election Sunday (September 2026)
Attack Vector:

🕵️ Pre-positioning (Weeks Before): Compromise MCP server, inject subtle bias in AI content generation
⚡ Activation (Election Day): Publish false exit poll data, fabricate early vote counts
📢 Amplification (Social Media): Coordinate with bot networks to spread misinformation
🔄 Persistence (Post-Election): Maintain doubt about election integrity

Impact:

🏛️ Erosion of public trust in Swedish election results
🌐 International media attention questioning Swedish democracy
📉 Long-term reputational damage to Riksdagsmonitor
⚖️ Potential legal liability for spreading false information

Mitigation:

🚨 Pre-Election: Freeze AI content generation 48h before election (manual mode only)
👁️ During Election: Heightened human review, no automated political data publication
✅ Post-Election: Cross-verify all results with official Riksdag sources before publication
📋 Incident Response: Pre-drafted public statement, CEO accountability, transparent correction process

gh-aw Election Protection:

SafeOutputs: Enhanced content validation rules active during election periods
AWF: Stricter domain allowlist (only riksdagen.se and val.se during election mode)
Token budget: Reduced to prevent burst generation attempts
Mandatory human gate: ALL content requires explicit human approval

Residual Risk: MEDIUM (2.5/10) - Accept risk with enhanced monitoring during high-stakes events

🤖 Scenario: AI Model Compromise via Prompt Injection

Threat Actor: Hacktivist / Politically Motivated Attacker
Objective: Inject political propaganda into AI-generated content
Attack Vector:

📝 Craft Injection: Create GitHub issue or PR comment containing adversarial prompts
🔄 Agent Processing: Hope AI agent processes crafted content as instructions
📊 Content Manipulation: Generate biased or misleading political content
🌐 Publication: Bypass review to publish manipulated content

gh-aw Defenses:

✅ Plan-level trust: Workflow decomposition prevents single-point injection
✅ Tool allowlisting: Agent cannot execute arbitrary commands
✅ SafeOutputs: All writes go through content validation
✅ Read-only execution: Agent cannot modify source directly
✅ Human review: PR approval required before any content merges

Residual Risk: LOW (1.5/10) - gh-aw's multi-layer defense effectively neutralizes prompt injection attacks

🏛️ Scenario: Democratic Data Source Manipulation

Threat Actor: Insider (Malicious Employee at Data Provider) or Supply Chain Attacker
Objective: Subtly alter parliamentary data to create false narratives
Attack Vector:

🎯 Target Selection: Identify high-value data fields (vote counts, committee assignments)
🔧 Subtle Modification: Change a single vote, alter committee membership dates
🤖 Amplification: Rely on AI to propagate subtle errors across all language versions
📰 Narrative Building: Use accumulated small errors to build false political narratives

gh-aw Defenses:

✅ MCP verification: Data retrieved through validated MCP server endpoints
✅ Cross-source validation: Multiple data sources compared for consistency
✅ Anomaly detection: Statistical outliers flagged for human review
⚠️ GAP: No real-time data integrity monitoring across all sources

Residual Risk: LOW (2.0/10) - Multiple verification layers, but subtle one-off errors may pass

Trike Risk-Centric Approach

Trike focuses on acceptable risk and security auditing, ensuring every threat has an explicit risk treatment decision — fully aligned with Hack23 ISMS policy.

Trike Concept	Riksdagsmonitor Application	Implementation
Actor → Asset → Action model	Threat agent → Crown Jewel → Attack type mapping	7 threat agent profiles × 5 Crown Jewels × STRIDE actions
Acceptable Risk Definition	CEO-defined risk tolerance thresholds	Risk Score ≤ 3.2/10 acceptable; 0 CRITICAL risks tolerated
Threat Enumeration Completeness	All actor-asset-action triples evaluated	52 STRIDE threats + 18 AI/LLM threats = 70 total threat entries
Permission Model	Intended vs. implemented access rights	GitHub OIDC scopes, AWS IAM policies, MCP server access controls
Risk Treatment Tracking	Every threat has explicit treatment	0 AVOID, 48 MITIGATE, 4 TRANSFER, 18 ACCEPT (70 threats, 100% coverage)
Audit Trail	All changes tracked to threat model	Git commit history, quarterly review schedule

Trike Benefits for Riksdagsmonitor:

✅ Auditability: Every threat has explicit MITIGATE/TRANSFER/ACCEPT decision
✅ Completeness check: Actor-asset-action matrix prevents threat omissions
✅ Democratic accountability: CEO-level risk acceptance for all residual risks
✅ Continuous improvement: Risk threshold adjustments tracked over time

⚖️ Enhanced Risk-Centric Analysis

Following Hack23 Threat Modeling Policy § 4.5, we provide quantitative risk analysis with business impact.

Risk Scoring Methodology

Likelihood Scale (1-5):

5 (CRITICAL): >80% probability within 12 months
4 (HIGH): 60-80% probability
3 (MEDIUM): 30-60% probability
2 (LOW): 10-30% probability
1 (VERY LOW): <10% probability

Impact Scale (1-10):

10 (CATASTROPHIC): >$100K loss, mission failure, severe reputation damage
8 (HIGH): $50K-$100K loss, major reputation damage
5 (MEDIUM): $10K-$50K loss, moderate reputation impact
3 (LOW): $1K-$10K loss, minor reputation impact
1 (MINIMAL): <$1K loss, negligible impact

Risk Score: Likelihood (1-5) × Impact (1-10) = Risk Score (1-50 scale → normalized to 0-10)

Democratic Accountability Procedures

Incident Response for Published Misinformation

Severity Classification:

Severity	Definition	Response Time	Public Statement Required	Example
CRITICAL	Completely fabricated parliamentary data published	< 4 hours	Yes (CEO)	Fake vote results, non-existent proposition
HIGH	Significant factual error with reputational impact	< 12 hours	Yes (project lead)	Wrong vote margin (175-174 vs. 176-173), misattributed committee
MEDIUM	Minor factual error, limited visibility	< 24 hours	No (correction notice)	Typo in minister name, incorrect date
LOW	Stylistic issue, translation nuance	< 72 hours	No (silent correction)	Word choice in translation, formatting inconsistency

Correction Protocol:

Detection: PR reviewer, user report, or automated validation failure
Classification: Assign severity (CRITICAL/HIGH/MEDIUM/LOW)
Immediate Action:
- CRITICAL/HIGH: Remove article immediately (Git revert)
- MEDIUM/LOW: Mark for correction (next release cycle)
Investigation: Root cause analysis (hallucination? MCP error? reviewer oversight?)
Correction: Create corrected article version with changelog
Public Statement (if required):
- Transparent acknowledgment of error
- Explanation of root cause (if appropriate)
- Preventive measures implemented
- CEO accountability signature
Prevention: Update validation gates, reviewer training, or automated checks

Transparency Commitment

Public Incident Log: All CRITICAL and HIGH severity incidents documented in GitHub Issues (public) with:

Incident description
Root cause analysis
Impact assessment
Corrective actions
Preventive measures
CEO accountability statement

Example PUBLIC Incident Disclosure:

Incident #2026-001: Fabricated Vote Margin Published (2026-03-15)

Severity: HIGH
Detection: PR reviewer post-publication (within 6 hours)
Description: AI-generated article reported incorrect vote margin (175-174) for motion H901:23. Actual margin was 176-173.
Root Cause: AI hallucination (Claude Opus 4.8 non-determinism). Document ID was correct (H901:23), but vote arithmetic was fabricated. Impact: Misinformation visible to ~500 users before correction. No external media amplification.
Corrective Actions:

Article removed within 4 hours of detection

Corrected version published with changelog

Email notification to known stakeholders

Preventive Measures:

Implemented automated vote margin verification against Riksdag API (Q1 2026 accelerated)

Enhanced PR review checklist (vote arithmetic mandatory check)

Reviewer training on AI hallucination detection

Accountability: James Pether Sörling, CEO - Full responsibility for incident and prevention.

🌐 IMF Integration — STRIDE Threats (Current State)

Effective: 2026-04-24 · Authoritative hub: analysis/imf/README.md · analysis/imf/agentic-integration.md · analysis/imf/indicators-inventory.json · analysis/imf/data-dictionary.md · .github/aw/ECONOMIC_DATA_CONTRACT.md

IMF-specific STRIDE threats

ID	Element	STRIDE	Description	Likelihood	Impact	Mitigation
T-IMF-01	IMF cache (filesystem)	Tampering	Vintage substitution — older WEO vintage swapped for newer label	LOW	HIGH	Vintage-tagged filenames; SHA-256 pin in cache index; supersedes-chain audit
T-IMF-02	IMF egress path	Information disclosure	IMF data is public macro statistics with no PII; SDMX 3.0 requests transmit the `IMF_SDMX_SUBSCRIPTION_KEY` (Azure APIM `Ocp-Apim-Subscription-Key` header) which gates throttle/quota only. Compromise of the key would let an attacker exhaust IMF rate quota under our identity but expose no confidential data.	LOW	LOW	Key stored only as a GitHub Actions secret (`IMF_SDMX_SUBSCRIPTION_KEY`, with `_SECONDARY` rotation hot-spare); `::add-mask::` applied in CI logs; never written to disk; rotation playbook in `analysis/imf/agentic-integration.md` §"Pre-warm gate"
T-IMF-03	IMF API	DoS	Workflow exceeds IMF rate limit (~30 req/min) → blocks article generation	MEDIUM	MEDIUM	Cache-first; self-imposed ≤30 req/min; exponential back-off; documented in `analysis/imf/agentic-integration.md`
T-IMF-04	IMF citation in article	Repudiation	Article cites "IMF projects X" without vintage label → unauditable claim	MEDIUM	MEDIUM	`economicProvenance` block required in front-matter; ECONOMIC_DATA_CONTRACT v2.1 banned phrases
T-IMF-05	`tsx scripts/imf-fetch.ts`	Elevation of privilege	Supply-chain tampering of IMF fetch script	LOW	HIGH	Script in-repo; reviewed; no dynamic eval; harden-runner egress audit
T-IMF-06	IMF data licence	Repudiation	Article reuses IMF figure without attribution	LOW	MEDIUM	Article footer template auto-emits IMF citation; lint enforces
T-IMF-07	IMF cache fallback	Spoofing	Stale cached vintage served as current → reader misinformed	LOW	MEDIUM	Vintage-age annotation rule (>6 mo → flagged); ECONOMIC_DATA_CONTRACT v2.1

IMF mitigations cross-reference

All mitigations are codified in:

analysis/imf/data-dictionary.md — vintage discipline + dataflow quirks
analysis/imf/agentic-integration.md — seven-step integration contract
.github/aw/ECONOMIC_DATA_CONTRACT.md — banned phrases + provenance schema
scripts/imf-context.ts — runtime enforcement
tests/imf-context.test.ts + tests/imf-inventory.test.ts — regression prevention

Egress hosts (allow-list): www.imf.org (Datamapper REST · WEO/FM, unauthenticated), api.imf.org (SDMX 3.0 REST · IFS/BOP/DOTS/GFS/PCPS/ER/MFS_IR/MFS_PR, subscription-key authenticated via the Azure APIM Ocp-Apim-Subscription-Key header / IMF_SDMX_SUBSCRIPTION_KEY secret). Both HTTPS-only; payloads are public macro statistics with no PII.

Canonical rule. Every economic claim in a Riksdagsmonitor article cites an IMF dataflow first; World Bank citations are reserved for governance, environment and social residue (the classes IMF does not publish). SCB is the Swedish-specific ground truth layer. See ECONOMIC_DATA_CONTRACT.md v2.1 for the banned-phrase list and vintage discipline (>6 mo → annotation).

🏛️ Statskontoret Integration — STRIDE Threats

Effective: 2026-04-25 · Classification: Public · Entry point: scripts/statskontoret-fetch.ts · Source: www.statskontoret.se.

Statskontoret ingestion introduces a public-data trust boundary for Swedish agency structure and budget outturn files. It is unauthenticated, read-only and optional enrichment, but the integrity of parsed figures matters for political-intelligence claims.

ID	Asset / flow	STRIDE	Threat	Likelihood	Impact	Mitigations
T-STATS-01	`www.statskontoret.se` page discovery	Spoofing	DNS/TLS interception or lookalike page returns false download links	LOW	MEDIUM	HTTPS-only egress, allow-list `www.statskontoret.se`, source URL recorded in payload and `.meta.json`, PR review of persisted diffs.
T-STATS-02	Excel / CSV ZIP payload	Tampering	Workbook or archive content modified upstream or in transit	LOW	HIGH	TLS transport, local parser contract checks, typed `StatskontoretError`, persisted raw/derived artifacts with provenance sidecars, reviewer diff inspection.
T-STATS-03	Headcount aggregation	Information integrity	Header drift maps wrong columns to `År`, `Departement`, `Myndighet`, or `Årsarbetskrafter`	MEDIUM	MEDIUM	Header-family matching documented in `analysis/statskontoret/data-dictionary.md`, unit tests for workbook parsing and Swedish number handling, fallback to no derived output if required fields cannot be resolved.
T-STATS-04	CLI invocation	Repudiation	Article cites agency headcount or budget outturn without source page/year/status	MEDIUM	MEDIUM	`discover` captures source page, URL, year/month/status and `last-modified`; persisted sidecars include `dataset`, `artifact`, `fetchedAt`, and `mcpTool: statskontoret-ts-client`.
T-STATS-05	Source availability	Denial of service	Statskontoret page unavailable or workbook fetch times out	MEDIUM	LOW	15s timeout, optional-enrichment semantics, cache-first reuse of `analysis/data/statskontoret/`, article generation can omit context rather than fail.
T-STATS-06	XLSX/ZIP parsing dependency	Elevation of privilege	Malicious archive attempts parser/resource abuse	LOW	HIGH	`jszip` pinned in npm lock/SBOM, GitHub Advisory Database reviewed, no dynamic eval, no script execution from workbooks, tests exercise parser edge cases.

Residual risk and classification

Residual risk: LOW-MEDIUM integrity risk due to upstream data or workbook-schema drift; handled by provenance, test coverage and human review.
Privacy: no PII or credentials; public authority and aggregate budget data only.
CIA: Public / High Integrity / Medium-High Availability for derived article context.

📊 SCB Integration — STRIDE Threats

Effective: 2026-05-30 · Classification: Public · Entry point: scripts/scb-fetch.ts · Client: scripts/scb-client.ts / scripts/scb-context.ts · Sources: AWF MCP gateway route to the scb MCP server (primary) and direct MCP relay https://scb-mcp.onrender.com/mcp (DIRECT_SCB_SERVER_URL fallback) · Cache: analysis/data/scb/.

SCB (Statistics Sweden) supplies the Swedish-specific ground-truth statistics layer (population, labour, economy, public finance). The integration is entirely MCP-based: inside the AWF sandbox it routes through the MCP gateway (host.docker.internal:<port>/mcp/scb); outside the sandbox it falls back to the community-hosted MCP relay on Render (https://scb-mcp.onrender.com/mcp). There is no direct SCB REST/PXWeb HTTP client — the trust boundary is between the two MCP transport paths, mitigated by cache-first/optional-enrichment semantics and provenance discipline.

ID	Asset / flow	STRIDE	Threat	Likelihood	Impact	Mitigations
T-SCB-01	`scb-mcp.onrender.com` MCP relay	Spoofing	Third-party relay impersonated or DNS/TLS-intercepted, returning forged table data	LOW	HIGH	HTTPS-only egress; allow-list `scb-mcp.onrender.com`; `DIRECT_SCB_SERVER_URL` selects the direct MCP relay when AWF gateway is unavailable; source URL + table id recorded in provenance.
T-SCB-02	JSON-stat / PXWeb payload	Tampering	Relay or upstream mutates statistic values, footnotes, or contents codes	LOW	HIGH	Typed MCP client contract checks; persisted raw/derived artifacts with `.meta.json` sidecars; reviewer diff inspection on persisted `analysis/data/scb/`.
T-SCB-03	Table-cell mapping	Information integrity	Variable/value-code drift maps wrong dimension (region, period, contents) to a cell	MEDIUM	MEDIUM	Metadata fetched per table before query; value-code validation; unit tests for SCB client parsing; omit context rather than emit unmapped figures.
T-SCB-04	SCB citation in article	Repudiation	Article cites "SCB reports X" without table id / vintage → unauditable claim	MEDIUM	MEDIUM	Provenance block records `mcpTool`, table id, `fetchedAt`; ECONOMIC_DATA_CONTRACT vintage discipline applies to the Swedish ground-truth layer.
T-SCB-05	MCP relay availability	Denial of service	Render relay cold-start or MCP timeout blocks enrichment	MEDIUM	LOW	15s timeout (`DEFAULT_TIMEOUT`); cache-first reuse; optional-enrichment semantics; retry with backoff (`DEFAULT_MAX_RETRIES`).
T-SCB-06	`tsx scripts/scb-fetch.ts`	Elevation of privilege	Supply-chain tampering of fetch/parse path	LOW	HIGH	Script in-repo; reviewed; no dynamic eval; dependencies pinned in npm lock/SBOM; harden-runner egress audit.

SCB residual risk

Residual risk: LOW-MEDIUM integrity risk concentrated in the third-party MCP relay; mitigated by cache-first/optional-enrichment semantics and provenance sidecars.
Privacy: no PII; public aggregate national statistics only.
CIA: Public / High Integrity / Medium Availability (optional enrichment).

🌍 World Bank Integration — STRIDE Threats

Effective: 2026-05-30 · Classification: Public · Client: scripts/world-bank-client.ts / scripts/world-bank-context.ts · Consumer: scripts/populate-analysis-data.ts · Source: https://api.worldbank.org/v2 (unauthenticated REST) · Hub: analysis/worldbank/README.md · analysis/worldbank/indicator-policy-mapping.md.

The World Bank integration is scope-restricted by contract: it supplies only the governance, environment, social and demographic residue that the IMF does not publish (e.g. Worldwide Governance Indicators, source=75). It is never used for economic context — that role is canonical to the IMF. The dominant risk is therefore contract violation (misuse as an economic source) as much as classic data-integrity threats.

ID	Asset / flow	STRIDE	Threat	Likelihood	Impact	Mitigations
T-WB-01	`api.worldbank.org/v2` egress	Spoofing	DNS/TLS interception returns forged indicator series	LOW	MEDIUM	HTTPS-only egress; allow-list `api.worldbank.org`; source URL + indicator code recorded in provenance.
T-WB-02	Indicator series payload	Tampering	Upstream or in-transit mutation of governance/environment values	LOW	MEDIUM	TLS transport; typed client contract checks; persisted artifacts with provenance sidecars; reviewer diff inspection.
T-WB-03	Indicator-class selection	Information integrity	World Bank figure used for economic context, violating the canonical IMF-first rule	MEDIUM	HIGH	`indicator-policy-mapping.md` restricts allowed classes (governance/environment/social/demographic); ECONOMIC_DATA_CONTRACT bans WB economic claims; lint/tests enforce.
T-WB-04	WB citation in article	Repudiation	Article cites WB indicator without code/vintage/source → unauditable	LOW	MEDIUM	Provenance block records indicator code + `fetchedAt`; footer attribution template.
T-WB-05	API availability	Denial of service	World Bank API timeout blocks enrichment	LOW	LOW	Cache-first; optional-enrichment semantics; article can omit residue context rather than fail.
T-WB-06	`world-bank-client.ts` fetch path	Elevation of privilege	Supply-chain tampering of fetch/parse path	LOW	MEDIUM	Script in-repo; reviewed; no dynamic eval; dependencies pinned in npm lock/SBOM; harden-runner egress audit.

World Bank residual risk

Residual risk: LOW; the binding control is the canonical IMF-first contract that confines World Bank to non-economic residue.
Privacy: no PII; public country-level indicators only.
CIA: Public / High Integrity / Low-Medium Availability (optional residue enrichment).

🔍 Riksrevisionen (RiR) Follow-up Integration — STRIDE Threats

Effective: 2026-05-30 · Classification: Public · Entry point: scripts/fetch-rir-followups.ts · Client: scripts/rir-followups-client.ts · Source: Riksdag/Regeringen via the riksdag-regering-mcp server (doktyp=skr skrivelse responses to RiR audit reports) · Store: data/rir-followups.json (schema: schemas/rir-followups-schema.json).

The RiR follow-up tracker matches government skrivelse responses against National Audit Office (Riksrevisionen) reports to surface oversight accountability — including overdue-response alerts. Because it generates accountability claims about whether the government acted on audit findings, the integrity of the report↔skrivelse matching and the deadline arithmetic are the principal threats.

ID	Asset / flow	STRIDE	Threat	Likelihood	Impact	Mitigations
T-RIR-01	`riksdag-regering-mcp` `doktyp=skr` query	Spoofing	MCP relay impersonated or returns forged skrivelse documents	LOW	HIGH	HTTPS-only egress; allow-list `riksdag-regering-ai.onrender.com`; dok_id recorded in `data/rir-followups.json`; same trust boundary controls as the core MCP server.
T-RIR-02	`data/rir-followups.json`	Tampering	Follow-up status (open/responded/overdue) altered to misstate government accountability	LOW	HIGH	JSON Schema validation (`schemas/rir-followups-schema.json`); committed artifact reviewed in PR diffs; provenance includes source dok_id and `fetchedAt`.
T-RIR-03	Report↔skrivelse matching	Information integrity	Wrong skrivelse matched to a RiR report → false "responded/ignored" claim	MEDIUM	HIGH	Deterministic matching keyed on report reference; schema-validated linkage; unit/regression tests; human review before publication.
T-RIR-04	Deadline computation	Information integrity	Mis-calculated follow-up window emits false overdue/compliant alert	MEDIUM	MEDIUM	Documented 4-month statutory window; date arithmetic under test; alert thresholds reviewed.
T-RIR-05	RiR/Riksdag accountability citation	Repudiation	Article asserts government "failed to respond" without source dok_id/date	MEDIUM	MEDIUM	Provenance block records dok_id, response date, status; ISMS editorial review for accountability claims.
T-RIR-06	Source availability	Denial of service	Riksdag MCP/API unavailable blocks follow-up refresh	MEDIUM	LOW	Cache-first reuse of `data/rir-followups.json`; optional-enrichment semantics; stale-data annotation.

RiR residual risk

Residual risk: LOW-MEDIUM; matching and deadline integrity are the binding risks, mitigated by schema validation, tests and mandatory human review of accountability claims.
Privacy: no PII; public audit reports and government documents only.
CIA: Public / High Integrity / Medium Availability.
