August core library

The compiler installs this matching package for august.io: console, file, and command-line capabilities with native adapters. The compiler also supplies august.collections for bounded half-open integer ranges, pure data processing, stable sorting and bounded isolated worker mapping, and august.math for checked integers and exact bounded decimals. The august.errors module adds deliberate typed causes and source context. The august.values module supplies validated calendar dates, exact millisecond durations, HTTP URLs, token IDs, portable relative paths and bounded UTF-8 text. Public contracts and Javadoc are in august/io; the API reference explains them.

JSON, time, stores, web helpers, and crypto are optional source packages. Use the package guide to add them from a public repository.
