Corner cases
The inputs that break code, ready to test
Time zone aliases, look-alike Unicode characters, decimal commas, malformed CSV rows and API requests one field away from valid. These test packs, reference tables and checkers let your agent try the hard inputs before your users do.
85 components in 7 groups, each at the exact version the library release of October 9, 2026 serves.

- Dates, times and time zonesIANA time zone tables with aliases, abbreviations and offsets, RFC 3339 helpers, date formats by country, and checkers for out-of-order timestamps and missed deadlines.
- Text, Unicode and encodingsLook-alike Unicode characters, Unicode blocks and emoji tables, base64 and base58 validators, and normalizers for whitespace, Unicode and personal data in free text.
- Numbers, currencies and localesDecimal and group separators by locale, currency formats and their minor units, phone number formats, radix parsing and exact comparison of two proportions.
- CSV files and recordsColumn profiles, field rule checks, merges of several sources and duplicate finders for CSV records.
- Names, addresses and identifiersAddress line parsing, name capitalisation, company suffixes, email and website repair, postal code formats for 246 countries, and validators with check digits.
- JSON Schema and API requestsJSON Schema 2020-12 conformance test groups, and API request cases that each change one field of a valid request and expect exactly one validation error.
- Files, transfers and 3D exportsFile transfers in checked parts, glTF and Godot checkers that catch lost animation and joints, and conformance tools for TOML parsers, HTTP/2 servers and Matroska files.
How your agent uses them
- Your agent searches Baltor for the step it is on and gets names, sizes and licences, never file bodies.
- It picks one component at an exact version and reads its file list, where every file names its SHA-256 checksum.
- It downloads exactly those files into your project, where your harness finds them, and checks each one against its checksum.
Why it matters
Most bugs arrive with inputs nobody wrote a test for. A test pack that already holds the awkward cases turns them into one more check your agent runs, instead of a report from production.
