Update the DDL in `server/db/index.ts` -2. Add the column name to `SAFE_COLUMNS` in `QueryBuilder.ts` -3. Update the relevant domain type in `server/types/` -4. Update the repository to select/insert the new column - -Example: Adding `updated_at` to `market_calls` - -```typescript -// 1. Update DDL -const DDL = ` - CREATE TABLE IF NOT EXISTS market_calls ( - ... - created_at TEXT NOT NULL, - updated_at TEXT NOT NULL -- NEW - ); -`; - -// 2. Update QueryBuilder.ts -const SAFE_COLUMNS = new Set([ - // ... existing columns - 'updated_at', // NEW -]); - -// 3. Update types -export interface MarketCall { - // ... existing fields - updatedAt: string; // NEW -} - -// 4. Update repository -const qb = new QueryBuilder('market_calls') - .select(['id', 'title', 'quarter', 'date', 'thesis', 'tickers', 'snapshot', 'created_at', 'updated_at']) // ADDED - .where('id = ?', [id]); -``` - ---- - -## Performance: Statement Caching - -`DatabaseConnection` automatically caches prepared statements. The first execution of a query compiles it; subsequent executions reuse the compiled statement. - -```typescript -// First call: compiles the statement (1.5ms overhead) -const qb1 = new QueryBuilder('holdings').select(['ticker', 'shares']).where('type = ?', ['stock']); -db.all(qb1); // ~1.5ms - -// Second call: reuses the cached statement (0.1ms) -const qb2 = new QueryBuilder('holdings').select(['ticker', 'shares']).where('type = ?', ['etf']); -db.all(qb2); // ~0.1ms (same SQL template) -``` - -Cache key is the complete SQL string. If you generate different SQL, it creates a new cached statement. - ---- - -## Transactions: Atomic Operations - -Use `db.transaction()` to execute multiple queries as a single atomic unit. If any query fails, all are rolled back. - -```typescript -db.transaction(() => { - // Create a market call - const qb1 = new QueryBuilder('market_calls') - .insert(['id', 'title', ...], [callId, 'Q4 Earnings', ...]); - db.run(qb1); - - // Add related tickers as separate records (if you had a separate table) - for (const ticker of tickers) { - const qb2 = new QueryBuilder('call_tickers') - .insert(['call_id', 'ticker'], [callId, ticker]); - db.run(qb2); - } - - // If ANY query fails, BOTH are rolled back - // If all succeed, both are committed -}); -``` - ---- - -## Audit Trail: Compliance & Debugging - -The `QueryAudit` class tracks every database operation automatically. - -### Built-in Features - -```typescript -const audit = db.getAudit(); - -// Get the last 100 queries -const recent = audit.recent(100); - -// Filter by action type -const writes = audit.byAction(AuditAction.WRITE); - -// Generate a human-readable report -console.log(audit.report()); -``` - -### Custom Callback - -Send audit entries to a logging service or file: - -```typescript -const audit = new QueryAudit(async (entry) => { - if (entry.action === 'WRITE') { - // Log all mutations to your compliance logger - await complianceLogger.log({ - timestamp: entry.timestamp, - action: entry.action, - sql: entry.sql, - params: entry.params, - rowsAffected: entry.rowsAffected, - }); - } -}); - -const db = new DatabaseConnection(betterSqlite3Db, { audit }); -``` - ---- - -## Slow Query Logging - -By default, queries slower than 100ms are logged to `console.warn`: - -```typescript -const db = new DatabaseConnection(betterSqlite3Db, { logSlowQueries: 100 }); -// Output: -// [SLOW QUERY] 234.56ms -// SELECT ticker, shares, cost_basis FROM holdings WHERE type = ? ORDER BY ticker ASC -``` - -Adjust the threshold based on your needs: - -```typescript -new DatabaseConnection(betterSqlite3Db, { logSlowQueries: 50 }); // warn on >50ms -new DatabaseConnection(betterSqlite3Db, { logSlowQueries: 5000 }); // warn on >5s -``` - ---- - -## Common Pitfalls & How to Avoid Them - -### ❌ DON'T: Hardcode user input in SQL - -```typescript -// NEVER DO THIS -const ticker = getUserInput(); // e.g. "AAPL'; DROP TABLE holdings; --" -const qb = new QueryBuilder('holdings') - .select(['ticker', 'shares']) - .where(`ticker = '${ticker}'`); // SQL INJECTION! -``` - -### βœ… DO: Use parameter placeholders - -```typescript -// ALWAYS DO THIS -const ticker = getUserInput(); -const qb = new QueryBuilder('holdings') - .select(['ticker', 'shares']) - .where('ticker = ?', [ticker]); // User input is a PARAMETER -``` - -### ❌ DON'T: Use string concatenation for column names - -```typescript -// NEVER DO THIS -const sortCol = getUserInput(); // e.g. "ticker; DELETE FROM holdings; --" -const qb = new QueryBuilder('holdings') - .select(['ticker', 'shares']) - .orderBy(`${sortCol}`); // COLUMN NAME INJECTION! -``` - -### βœ… DO: Column names come from your code, not user input - -```typescript -// ALWAYS DO THIS -const sortCol = getUserInput(); // e.g. "ticker" -const ALLOWED_SORT_COLS = ['ticker', 'shares', 'type']; - -if (!ALLOWED_SORT_COLS.includes(sortCol)) { - throw new Error('Invalid sort column'); -} - -const qb = new QueryBuilder('holdings') - .select(['ticker', 'shares']) - .orderBy(sortCol); // Whitelist prevents injection -``` - ---- - -## Testing - -The new abstractions make testing easier: - -```typescript -import { DatabaseConnection, QueryBuilder, QueryAudit } from '../db'; -import BetterSqlite3 from 'better-sqlite3'; - -describe('MarketCallRepository', () => { - let db: DatabaseConnection; - let repo: MarketCallRepository; - - beforeEach(() => { - // Use in-memory SQLite for tests - const rawDb = new BetterSqlite3(':memory:');

Market Context
+
10Y Treasury YieldRate
+
Benchmark risk-free rate. The higher it goes, the more bonds compete with stocks, and the more P/E multiples compress.
Regime: <2% LOW Β· 2–5% NORMAL Β· >5% HIGH
<2% Growth wins
2–5% Balanced
>5% Value wins
+ +
VIX β€” Volatility IndexRisk
+
The market's "fear gauge." Measures expected 30-day S&P 500 volatility. High VIX = elevated uncertainty β€” risk premiums rise and valuations compress.
Regime: <15 Calm Β· 15–25 Normal Β· >25 Elevated
<15 Calm
15–25 Normal
>25 Fear
+ +
Rate RegimeRegime
+
Derived from the 10Y yield. Controls how P/E gates are adjusted. In HIGH rate regimes, the multiplier tightens from 1.5Γ— to 1.2Γ— β€” future earnings are worth less when rates are high.
HIGH rates: P/E gate = S&P P/E Γ— 1.2 (stricter)
LOW Growth favored
NORMAL Balanced
HIGH Value favored
+ + +
Valuation
+
P/E RatioValuation
+
Price-to-Earnings. How many dollars you pay per $1 of annual profit. Uses trailing (audited) earnings β€” not analyst estimates. The most fundamental valuation gate.
Graham gate: <15Γ— Β· Mkt-Adj gate: S&P P/E Γ— 1.5 β‰ˆ 40Γ—
<15Γ— Graham
15–35Γ— Fair
>35Γ— Expensive
+ +
PEG RatioValuation
+
P/E adjusted for growth rate. A PEG of 1.0 means you pay exactly what the growth justifies β€” Peter Lynch's "fair price" benchmark. Below 1.0 = growth is cheap.
Gate: < 1.0 (Lynch standard) Β· Weight: 2
<1.0 Bargain
1.0–2.0 Fair
>2.0 Costly
+ +
DCF Safety MarginValuation
+
Two-stage discounted cash flow model. Compares intrinsic value (from future FCF) to today's price. Positive = undervalued. Negative = trading above fair value. Only fires when FCF > 0.

Quality
+
ROE %Quality
+
Return on Equity. Profit generated per $1 of shareholder equity. The best single proxy for whether management allocates capital well. Warren Buffett's preferred quality metric.
Gate: >15% preferred Β· Weight: 3 (highest tier)
>20% Exceptional
10–20% Decent
<10% Weak
+ +
Operating Margin %Quality
+
Operating profit as % of revenue. Measures core business efficiency before interest and tax. Expanding margins signal pricing power and operational leverage over time.
Varies by sector Β· Weight: 2
>20% Strong
10–20% Decent
<10% Thin
+ +
FCF Yield %Quality
+
Free Cash Flow yield. Real cash generated after capex, divided by market cap. Unlike earnings, FCF cannot be easily manipulated by accounting choices. Negative FCF is a hard gate failure.
Gate: FCF must be > 0 Β· Weight: 3 (highest tier)
>5% Strong
1–5% Adequate
<0% Negative
+ +
Gross Margin %Quality
+
Revenue minus cost of goods, as % of revenue. Shows product economics and pricing power before any overhead. High gross margin = room to invest in growth without destroying profitability.
Display only β€” not yet a hard gate Β· informational
>50% Premium
30–50% Decent
<30% Thin
+ + +
Risk
+
Debt / EquityRisk
+
Total debt divided by shareholders' equity. Measures financial leverage. Higher D/E means more debt relative to the equity cushion β€” raises distress risk when earnings decline.
Gate: <1.5Γ— (Graham) Β· Tech allowed up to 2.0Γ—
<0.5 Conservative
0.5–1.5 Acceptable
>1.5 Leveraged
+ +
Beta (Ξ²)Risk
+
Measures how much a stock moves relative to the S&P 500. Ξ² = 1.0 tracks the market. Ξ² = 2.2 means 2.2Γ— the move β€” in both directions. High beta stocks can gap down quickly on bad news.
Flag triggered: Ξ² > 1.5
<1.0 Low vol
1.0–1.5 Market-like
>1.5 High vol

52W Change %Momentum
+
Total price return over the past 52 weeks. Used with "From High" to detect strong momentum (uptrend) or deep dip (opportunity or distress) conditions.
Flag: β‰₯+50% uptrend Β· ≀-30% significant drawdown
≀-30% Drawdown
-30 to +30%
β‰₯+50% Uptrend

From 52W High %Momentum
+
How far below the 52-week peak the stock currently sits. Negative = below its recent high. Large negative values signal either dip opportunity (quality stocks) or distress (weak stocks).
