+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+**Substrate** is an open-source framework for human understanding, meaning, and progress. It's a structured knowledge system for capturing, organizing, and analyzing different aspects of civilization—from problems and solutions to values, plans, and experiments.
+
+The project uses a hierarchical directory structure where each category contains structured markdown files that can reference each other. The primary interface for working with Substrate is AI-powered analysis, which can hold multiple components in context simultaneously and analyze relationships between them.
+
+## Repository Structure
+
+The repository is organized into distinct categories, each containing individual entries as markdown files or directories:
+
+- **Arguments/** - Structured logical arguments (deductive, inductive, etc.) about claims
+- **Claims/** - Assertions that can be supported by arguments
+- **Data-Sources/** - References to data that supports or refutes claims
+- **Experiments/** - Scientific or social experiments related to hypotheses
+- **Frames/** - Mental models or worldviews that shape how plans are created
+- **Funding-Sources/** - Potential or actual funding for projects
+- **Ideas/** - Concepts that could become solutions or projects
+- **Models/** - Ways of understanding the world (beliefs, frameworks)
+- **Organizations/** - Groups working on related problems/solutions
+- **Outcomes/** - Results from projects or experiments
+- **People/** - Individuals relevant to the project
+- **Plans/** - Comprehensive governance plans (like `us-plan1-miessler.md`)
+- **Problems/** - Issues facing humanity at various scales
+- **Projects/** - Active initiatives working toward solutions
+- **Results/** - Specific outputs from experiments or projects
+- **Risks/** - Potential negative consequences of plans or projects
+- **Solutions/** - Proposed approaches to problems
+- **Threats/** - External challenges to plans or values
+- **Values/** - Core principles that guide decision-making
+
+## File Naming Convention
+
+Files use a structured naming format:
+- **Format**: `[CATEGORY-ID]—[Descriptive_Name]`
+- **Example**: `AR-12934—AIs_Are_Capable_of_Understanding`
+- The ID helps with cross-referencing between components
+- Underscores separate words in the descriptive name
+
+## Working with Substrate
+
+### Key Principles
+
+1. **Interconnected System**: Components reference each other (Problems link to Solutions, Plans reference Values, etc.)
+2. **Transparency**: Plans and arguments should be explicit about their reasoning and assumptions
+3. **AI-First Interface**: The system is designed to be navigated and analyzed by AI, which can hold multiple components in context
+4. **Structured Thinking**: Each category has a specific purpose and format
+
+### Plans Structure
+
+Plans (like `us-plan1-miessler.md`) follow the Telos framework and include:
+- **SCOPE**: What entity the plan covers
+- **CHALLENGES**: Key problems facing the entity
+- **MISSION**: Primary objectives
+- **STRATEGIES**: High-level approaches
+- **IDEAL WORLD**: Vision of desired future state
+
+Plans can also reference:
+- Problems, Solutions, Values, Models, Projects, Budgets, Metrics
+
+### Arguments Structure
+
+Arguments follow formal logical structures:
+- **Claim**: The assertion being argued
+- **Argument Style**: Type (deductive, inductive, abductive, etc.)
+- **Argument**: Step-by-step logical progression
+- Each step builds on previous ones to reach a conclusion
+
+## Common Development Tasks
+
+### Adding New Entries
+
+When adding new Problems, Solutions, Ideas, etc.:
+1. Create file with proper naming convention: `[CATEGORY-ID]—[Name]`
+2. Follow the structure of existing entries in that category
+3. Include cross-references to related components where appropriate
+4. Consider which Plans, Values, or Models the entry relates to
+
+### Analyzing Relationships
+
+When analyzing Substrate content:
+1. Read multiple related files to understand connections
+2. Look for explicit and implicit references between components
+3. Consider how Models/Values shape Plans and Solutions
+4. Trace Problems → Solutions → Projects → Outcomes chains
+
+### Contributing
+
+The project welcomes contributions via pull requests to modify Substrate object files. A web-based interface is planned to make contributions easier for non-coders.
+
+## Important Context
+
+- **Single-repo structure**: As of July 27, 2024, all components live in this monorepo
+- **Primary creator**: Daniel Miessler
+- **Video introduction**: https://www.youtube.com/watch?v=ky7ejowc_qY
+- **Blog post**: https://danielmiessler.com/p/introducing-substrate
+- **Mission**: Visualize human progress through structured knowledge
+
+## When Working with This Repo
+
+- Respect the structured format of each category
+- Maintain the naming conventions
+- Consider cross-references and relationships between components
+- Plans are meant to be comprehensive and transparent
+- The system is designed for AI analysis—keep content machine-readable
+- Most README.md files in subdirectories are minimal placeholders

+## Relationship with Research Projects
+
+The Data directory works in conjunction with `research/` directory to maintain clear traceability between research and resulting datasets.
+
+**Research → Data Workflow:**
+
+1. **Input**: Research projects use `Data/sources/` to access external data APIs and endpoints
+2. **Analysis**: Research projects perform analysis, synthesis, and investigation  
+3. **Output**: Research projects produce curated datasets stored in `Data/` top-level
+4. **Documentation**: Research projects document their methodology, sources used, and resulting datasets

+```
+
+**Key Principles:**
+
+- Each dataset in `Data/` should include `source.md` documenting origin (research project or direct source)
+- Research projects should document which `Data/sources/` they used as inputs in their SOURCES.md
+- Research findings and methodology live in `research/`, curated datasets live in `Data/`
+- Bidirectional links maintain complete traceability from source → research → dataset
+
+**Benefits:**
+
+- Clear provenance: Always know where data came from and how it was produced
+- Reproducibility: Research methodology is documented and linked to outputs  
+- Reusability: Other research can reference existing datasets and their origins
+- Quality: Traceability enables verification and validation of data quality

+
+### Source Documentation
+
+Each data source has comprehensive documentation in `Data/sources/`:
+

+
+### Data Flow
+
+```
+Source Agencies (BEA, BLS, Treasury, etc.)
+    ↓
+FRED API (aggregates most series)
+    ↓
+update.ts automation script
+    ↓
+US-Common-Metrics.md (human-readable)
+us-metrics-current.csv (machine-readable)
+```
+
+---
+
+## Methodology
+
+### Metric Selection Criteria
+
+Metrics were selected based on:
+
+1. **Economic Significance**: Core indicators watched by economists, policymakers, markets
+2. **Public Interest**: Commonly cited in news, policy discussions
+3. **Authoritative Source**: Must come from official government agencies
+4. **Regular Updates**: Sufficient update frequency to track changes
+5. **Historical Availability**: Long time series for trend analysis
+
+### Data Aggregation Approach
+
+1. **FRED-First**: Most metrics sourced via FRED API, which standardizes access to data from multiple agencies
+2. **Direct API**: Some metrics (gas prices, federal debt) fetched directly from source agency APIs
+3. **No Transformation**: Values presented as-is from source; no smoothing, adjustment, or calculation beyond what source provides
+4. **Full Attribution**: Every value includes source, FRED series ID (if applicable), and timestamp
+
+### Update Process
+
+1. `update.ts` fetches latest values from all APIs
+2. Values written to `US-Common-Metrics.md` in appropriate cells
+3. Current values exported to `us-metrics-current.csv`
+4. Historical values appended to `us-metrics-historical.csv`
+5. Update log written to `update.log`
+
+### Handling Revisions
+
+Many economic indicators are revised after initial release:
+
+- **Advance/Preliminary/Final**: GDP has three releases
+- **Benchmark Revisions**: Employment data revised with annual benchmarks
+- **Seasonal Factor Updates**: Seasonal adjustments recalculated annually
+
+We always show the **most recent available value**, which may differ from initially reported figures.
+
+---
+
+## Access Conditions
+
+### License
+All underlying data is **public domain** (U.S. government work). This aggregation is part of the Substrate project under MIT license.
+
+### API Keys Required
+
+All APIs are free but most require registration:
+
+| Source | Registration | Rate Limit |
+|--------|--------------|------------|
+| FRED | [Get key](https://fred.stlouisfed.org/docs/api/api_key.html) | 120 req/min |
+| EIA | [Get key](https://www.eia.gov/opendata/register.php) | 1000 req/hour |
+| Census | [Get key](https://api.census.gov/data/key_signup.html) | 500 req/day |
+| BLS | Optional (higher limits) | 500 req/day (no key) |
+| Treasury | None required | Reasonable use |
+| CDC WONDER | None required | Fair use |
+| EPA | Email request | 10 req/min |
+
+### Environment Variables
+
+```bash
+export FRED_API_KEY="your_key"
+export EIA_API_KEY="your_key"
+export CENSUS_API_KEY="your_key"
+export BLS_API_KEY="your_key"  # Optional
+```
+
+---
+
+## Known Limitations
+
+### Coverage Gaps
+
+1. **Stock Indices**: S&P 500, DJIA not always available via free APIs (licensing restrictions)
+2. **Real-Time Data**: Most metrics have publication lag (see individual sources)
+3. **Regional Data**: This dataset focuses on national metrics; state/local data available from sources directly
+
+### Methodological Limitations
+
+1. **Aggregation Layer**: We don't collect primary data; we aggregate from official sources
+2. **Revision Timing**: We fetch current values; historical revisions may not be captured
+3. **Definition Changes**: Source agencies sometimes change definitions (noted in source docs)
+
+### What This Dataset Is NOT
+
+- **Primary data collection** - we aggregate from authoritative sources
+- **Forecasts or projections** - historical and current data only
+- **Microdata** - aggregated indicators only; no individual records
+- **Real-time trading data** - publication lags vary from hours to months
+
+---
+
+## Integration with Substrate
+
+### Linked Components
+
+- **Problems**: Metrics quantify problems (e.g., PR-XXXXX - Economic Inequality → GINI Index)
+- **Solutions**: Metrics track outcomes (e.g., SL-XXXXX - Employment Programs → Unemployment Rate)
+- **Arguments**: Metrics provide evidence for claims
+- **Plans**: Metrics define KPIs for success measurement
+
+### Usage in Arguments
+
+When citing metrics in Substrate Arguments:
+
+```markdown
+**Claim**: Unemployment has decreased significantly since 2020.
+
+**Evidence**:
+- Unemployment Rate (U-3): 3.7% (November 2024)
+- Source: BLS/FRED (UNRATE)
+- Comparison: 14.7% (April 2020, pandemic peak)
+- Data: [US-Common-Metrics](../Data/US-Common-Metrics/US-Common-Metrics.md)
+```
+
+---
+
+## Maintenance
+
+### Update Frequency
+
+```bash
+# Manual update
+cd Data/US-Common-Metrics
+bun run update.ts
+
+# Scheduled update (via cron or GitHub Actions)
+0 6 * * * cd /path/to/Substrate && bun run Data/US-Common-Metrics/update.ts
+```
+
+### Quality Checks
+
+1. **Completeness**: All metrics should have values (missing = API issue)
+2. **Freshness**: Values should be within expected update window
+3. **Consistency**: Values should be plausible (outlier detection)
+4. **Sources**: All values should have source attribution
+
+### Contributing
+
+To add new metrics:
+
+1. Identify authoritative source
+2. Add source documentation to `Data/sources/DS-00XXX—Name/source.md`
+3. Add metric rows to `US-Common-Metrics.md`
+4. Update `update.ts` to fetch new metrics
+5. Submit PR with justification for addition

+- **Accuracy for Different Uses:** Excellent for trend analysis and point estimates
+
+---
+
+## Known Limitations and Caveats
+
+### Coverage Limitations
+
+**Geographic Gaps:**
+- Real-time retail gas prices vary by station; EIA reports regional averages
+- Some remote areas underrepresented in price surveys
+
+**Temporal Gaps:**
+- Daily oil prices available; daily gas prices not (weekly only)
+- Some historical data less frequent than current
+
+**Variable Gaps:**
+- Retail gas prices are averages; actual prices vary by station
+- Some proprietary trading data not captured
+
+### Methodological Limitations
+
+**Sampling Limitations:**
+- Gas price surveys sample stations; not census of all stations
+- Spot prices may not reflect all market transactions
+
+**Measurement Limitations:**
+- Retail prices are survey-based (may lag actual market)
+- Some prices are spot/futures; retail prices differ
+
+### How to Use Responsibly
+
+1. **Gas prices**: Use as indicator of trends; actual prices vary by location/station
+2. **Oil prices**: WTI is benchmark; actual crude prices vary by grade/location
+3. **Time lag**: Account for 1-7 day publication lag in analysis
+4. **Attribution**: Always cite EIA as source

+- **Comprehensiveness:** Fills critical gap for fiscal metrics in US-Common-Metrics
+
+---
+
+## Source Evaluation Narrative
+
+### Methodological Assessment
+
+**Data Collection Methodology:**
+- **Administrative Records:** Direct recording of Treasury operations
+- **Completeness:** 100% - all federal fiscal transactions recorded
+- **Validation:** Internal controls, GAO audit, reconciliation with Fed records
+- **Timeliness:** Daily updates for debt; monthly for budget statements
+
+**Error Characteristics:**
+- **Measurement Error:** Minimal (administrative data, not surveys)
+- **Known Issues:** Accounting treatments may change (documented); timing differences between cash and accrual
+- **Revisions:** Some figures revised as transactions settle
+
+### Currency Assessment
+
+**Update Characteristics:**
+- **Debt Data:** Daily (by 6 PM ET)
+- **Monthly Treasury Statement:** ~8th business day of following month
+- **Deficit/Surplus:** Monthly with annual final
+- **Reliability:** Highly consistent; legal obligation to publish
+
+### Objectivity Assessment
+
+**Potential Biases:**
+- **Political Bias:** Data is administrative (not discretionary); political leadership cannot alter figures
+- **Presentation Bias:** Different administrations may emphasize different metrics, but underlying data unchanged
+- **Transparency:** All data publicly available; methodology documented
+
+### Reliability Assessment
+
+**Consistency:**
+- **Internal Consistency:** Reconciled with Federal Reserve, CBO figures
+- **Temporal Consistency:** Long time series with consistent definitions
+- **Cross-source Consistency:** Matches Fed Z.1 Financial Accounts, CBO estimates
+
+### Accuracy Assessment
+
+**Validation Evidence:**
+- **GAO Audit:** Annual audit of Treasury financial statements
+- **Reconciliation:** Daily reconciliation with Federal Reserve
+- **Error Rate:** Minimal for administrative data
+
+---
+
+## Known Limitations and Caveats
+
+### Coverage Limitations
+
+**What's NOT Included:**
+- State and local government debt (separate sources)
+- Federal Reserve balance sheet (separate from Treasury debt)
+- Off-budget items (some military, emergency spending may be tracked differently)
+- Unfunded liabilities (Social Security, Medicare future obligations not counted as debt)
+
+**Temporal Gaps:**
+- Historical data format varies; modern APIs cover recent decades
+- Some older data requires accessing archived reports
+
+### Methodological Limitations
+
+**Accounting Treatments:**
+- Cash basis vs. accrual basis (MTS is cash; some reports accrual)
+- Intragovernmental holdings (Social Security surplus) counted differently
+- Debt ceiling periods may cause unusual timing patterns
+
+**Interpretation Cautions:**
+- "Debt ceiling" periods create artificial constraints/timing issues
+- Debt-to-GDP ratio requires GDP from separate source (BEA)
+- Nominal vs. inflation-adjusted comparisons require CPI data
+
+### How to Use Responsibly
+
+1. **Debt figures**: Total Public Debt Outstanding is headline number
+2. **Debt Held by Public**: Better measure of government's market borrowing
+3. **Deficit**: Use 12-month rolling or fiscal year (Oct-Sep) for trends
+4. **Context**: Always provide GDP comparison for meaningful interpretation
+

+
+## API Usage Examples
+
+### Get Total Public Debt Outstanding
+
+```bash
+curl "https://api.fiscaldata.treasury.gov/services/api/fiscal_service/v2/accounting/od/debt_to_penny?sort=-record_date&page[size]=1"
+```
+
+### Get Monthly Treasury Statement Summary
+
+```bash
+curl "https://api.fiscaldata.treasury.gov/services/api/fiscal_service/v1/accounting/mts/mts_table_5?sort=-record_date&page[size]=12"
+```
+
+### TypeScript Example
+
+```typescript
+interface DebtResponse {
+  data: Array<{
+    record_date: string;
+    tot_pub_debt_out_amt: string;
+    debt_held_public_amt: string;
+    intragov_hold_amt: string;
+  }>;
+}
+
+async function getTotalDebt(): Promise<DebtResponse> {
+  const response = await fetch(
+    "https://api.fiscaldata.treasury.gov/services/api/fiscal_service/v2/accounting/od/debt_to_penny?sort=-record_date&page[size]=1"
+  );
+  return response.json();
+}
+
+// Returns debt in dollars (e.g., "34123456789012.34")
+```

+# Research Projects
+
+## Purpose
+
+The `research/` directory contains completed research projects with their findings, methodology, and analysis. Research projects typically use external data sources from `Data/sources/` and produce curated datasets that are stored in `Data/`.
+
+## Relationship with Data Directory
+
+Research projects work in conjunction with the `Data/` directory:
+
+**Research → Data Workflow:**
+
+1. **Input**: Use `../Data/sources/` to access external data APIs and endpoints
+2. **Analysis**: Perform analysis, synthesis, and investigation
+3. **Output**: Produce curated datasets stored in `../Data/` top-level
+4. **Documentation**: Document methodology, sources used, and resulting datasets
+
+## Required Research Project Structure

+
+[Brief description of how raw data from sources was processed, cleaned, and analyzed]
+```
+
+## Key Principles
+
+1. **Traceability**: Always document which `Data/sources/` were used
+2. **Reproducibility**: Methodology should enable others to reproduce findings
+3. **Dataset Production**: Curated outputs go in `../Data/` with `source.md` linking back
+4. **Bidirectional Links**: Research → Data and Data → Research connections maintained
+5. **Source Citation**: Credit all external sources properly
+
+## Benefits of This Structure
+
+- **Provenance**: Clear lineage from source → research → dataset
+- **Reproducibility**: Research can be verified and repeated
+- **Reusability**: Future research can build on existing work
+- **Quality**: Traceability enables validation
+- **Discovery**: Easy to find research that used specific sources
