+## [0.1.0] - 2026-01-11
+
+### Added
+
+- **Multi-Resolver Ticker Enrichment**: Implemented stacked resolver architecture allowing multiple ticker resolution strategies with fallback logic
+- **Specialized Yahoo Finance Resolvers**:
+  - `YahooISINResolver`: High-accuracy ISIN-based ticker resolution
+  - `YahooNameResolver`: Advanced name-based search with Alphabet Inc Class A/C handling
+  - `YahooFullResolver`: Combined resolver using both strategies
+- **CLI Enhancements**:
+  - `--yahoo-isin`: Enable ISIN-only resolution
+  - `--yahoo-name`: Enable name-only resolution
+  - `--no-yahoo`: Disable automatic Yahoo Finance resolution
+  - Yahoo Finance resolution now enabled by default
+- **Coding Guidelines**: Added `CODING_GUIDELINES.md` with strict terminology standards for `ticker`, `name`, and `symbol`
+- **Comprehensive Test Suite**:
+  - Added 50+ new tests across 5 new test files
+  - `tests/cache.test.ts`: LocalFileTickerCache tests
+  - `tests/enricher_advanced.test.ts`: Multi-resolver stacking and edge cases
+  - `tests/file_resolver_extended.test.ts`: All file format variations
+  - `tests/resolvers/yahoo.test.ts`: Complete Yahoo resolver coverage
+  - Achieved 95%+ code coverage on resolvers and enrichment logic
+- **CI/CD Enhancements**:
+  - Added Prettier formatting check to CI pipeline
+  - Reorganized CI steps for fail-fast approach (format → type-check → lint → build → test)
+  - All quality gates now enforced automatically on every PR and push
+
+### Changed
+
+- **BREAKING**: Renamed `symbol` field to `name` in `ParsedTransaction` type to clearly distinguish company names from ticker symbols
+- **BREAKING**: `enrichTransactions` now accepts `resolvers: TickerResolver[]` (array) instead of `resolver: TickerResolver` (singular)
+- Refactored `TickerResolver` interface to require `name` property for better logging and identification
+- Updated all parsers (Avanza, Nordnet) to use `name` field instead of `symbol`
+- Enhanced Yahoo Finance integration with proper TypeScript types, eliminating all `any` usages
+- Improved currency enrichment with fallback chain: `quote()` → `quoteSummary()`
+- Updated documentation with resolver stacking examples and terminology reference
+
+### Fixed
+
+- Fixed documentation example showing incorrect `resolver` usage (now correctly uses `resolvers` array)
+- Removed backward compatibility for deprecated `symbol` field in `FileTickerResolver`
+- Fixed all ESLint warnings by adding proper TypeScript types throughout codebase
+
+### Removed
+
+- Removed `eslint.config copy.mjs` (leftover file with Next.js-specific config)
+- Removed backward compatibility for `symbol` field in ticker mapping files (JSON/CSV)
+
+### Documentation
+
+- Updated README with comprehensive examples for:
+  - Multi-resolver stacking
+  - All supported ticker mapping formats (JSON object/array, CSV)
+  - CLI usage with new resolver options
+- Added terminology standards section linking to `CODING_GUIDELINES.md`
+- Clarified distinction between `name` (company name) and `ticker` (stock symbol)
+
+### Technical Improvements
+
+- All 84 tests passing with zero linting warnings
+- 100% function coverage across all modules
+- Type-safe Yahoo Finance API integration
+- Proper error handling in all resolvers
+- Exchange filtering (NMS, NYQ, NGM) for higher quality ticker matches
+

+# Coding Guidelines
+
+## Terminology Standards
+
+### Ticker vs Name vs Symbol
+
+To maintain consistency across the codebase, always adhere to these naming conventions:
+
+- **`ticker`**: Use this for stock ticker symbols (e.g., "AAPL", "META", "GOOGL")
+  - Variable names: `ticker`, `resolvedTicker`, `stockTicker`
+  - Field names: `ticker`
+  - Function parameters: `ticker`
+
+- **`name`**: Use this for company/security names (e.g., "Apple Inc", "Meta Platforms A")
+  - Variable names: `name`, `companyName`, `securityName`
+  - Field names: `name`
+  - Function parameters: `name`
+
+- **`symbol`**: **DEPRECATED** - Do not use this term for company names
+  - If you encounter `symbol` in legacy code or external APIs, treat it as a `ticker`
+  - When refactoring, always replace `symbol` with either `ticker` or `name` based on context
+  - Exception: External API responses where `symbol` is the field name (cast/map to `ticker`)
+
+### Examples
+
+✅ **Correct:**
+
+```typescript
+interface Transaction {
+  name: string; // "Apple Inc"
+  ticker: string; // "AAPL"
+  isin: string; // "US0378331005"
+}
+
+function resolveTicker(isin: string, name: string): string {
+  // ...
+}
+```
+
+❌ **Incorrect:**
+
+```typescript
+interface Transaction {
+  symbol: string; // Ambiguous - is this a ticker or name?
+}
+
+function resolveSymbol(isin: string, symbol: string): string {
+  // ...
+}
+```
+
+### Rationale
+
+The term "symbol" is ambiguous in financial contexts. It can refer to:
+
+- A ticker symbol (AAPL)
+- A company name (Apple Inc)
+- A trading symbol on an exchange
+
+By strictly using `ticker` for stock symbols and `name` for company names, we eliminate confusion and make the codebase more maintainable.

@@ -28,7 +28,6 @@ We love support for new brokers! To add one:
     Create a new file in `src/parsers/` (e.g., `src/parsers/mybroker.ts`) implementing the `BrokerParser` interface.
 
 2.  ** Implement Logic**:
-
     - `name`: Unique name of the broker.
     - `canParse(row)`: A function returning `true` if this row belongs to this broker. Be specific (check unique headers).
     - `parse(row)`: Map the CSV row to the `ParsedTransaction` interface.
