## Changelog

All notable changes to the Nordic Company Registry project will be documented in this file.

### \[Unreleased]

### \[3.5] - 2026-04-01

#### Fixed

- Fixed OOM during refreshData by removing orgLookup Map (~150MB saved); matched SCB records are skipped since BV already provides address data

### \[3.4] - 2026-04-01

#### Fixed

- Fixed Sweden search returning empty addresses, legalForm, registrationDate, and industryCode by storing enriched company data in the KV index
- Index entries now include Bolagsverket address/registration fields and SCB address/industry fields
- SCB data is merged into matched Bolagsverket entries during index build (phase 2)
- Backward compatible: old-format index entries still work but require `refreshData` re-run for full data

### \[3.0.3] - 2026-03-30

#### Fixed

- Fixed KV Store persist taking 13+ minutes by limiting concurrent writes to 25 (was unbounded ~2,000 parallel API calls)
- Added progress logging during shard persistence

### \[3.0.2] - 2026-03-29

#### Fixed

- Fixed `ERR_STRING_TOO_LONG` crash during Sweden `refreshData` bulk indexing; ZIP entries now stream in 64 KB chunks
- Fixed OOM crash during `refreshData` by building the sharded index directly from BV/SCB streams instead of materialising the full merger map
- Fixed KV Store key validation error for Swedish diacritics (å, ä, ö) by hex-encoding shard keys

### \[3.0.0] - 2026-03-29

#### Added

- Sweden (SE) country support via Bolagsverket bulk data files (free, no API key required)
- New `searchMode: "refreshData"` input mode for bulk data download and indexing
- `SwedishOrgNumber` branded type with 10-digit format + Luhn check digit validation
- Streaming parsers for Bolagsverket (`;`-delimited, UTF-8) and SCB (`\t`-delimited, ISO-8859-1) bulk files
- Data merger joining Bolagsverket + SCB records by organisation number
- Sharded search index persisted to Apify Named Key-Value Store for fast name lookups
- Sweden live tests verifying bulk file download and parsing
- 188 new tests (387 total, up from 199)

#### Changed

- Strengthened branded type validators: `cvrNumber` validates 8-digit format, `businessId` validates `\d{7}-\d` pattern
- `NordicCompanySchema` name field now requires min(1) length
- `nordicCompanyId()` now guards against empty country/regNum inputs
- Updated all schemas to include SE country code

#### Fixed

- Fixed Apify deploy: `actor.json` version format changed from semver to MAJOR.MINOR
- Fixed `output_schema.json` description that incorrectly referenced removed Sweden
- Fixed stale `./node_modules/.bin/vp` references in live test file comments
- Added `adm-zip` as explicit dependency (was transitive)
- Swedish dissolved companies now correctly populate `dissolutionDate`

#### Changed
