Subpath exports

The package exposes focused entry points so a bundler pulls in only what you use.

Public

Stable. Changes follow semantic versioning; versioning and support says exactly what that promises, including how deprecations are handled and which Node versions are tested.

Entry	Contains
solve-engine	ExpressionEngine, createEngine, IEnginePackage, common types
solve-engine/engine	Engine internals for host integration
solve-engine/vm	Value, ValueType, value construction
solve-engine/format	formatValue and formatting settings
solve-engine/language	Completions, token categories, highlighting
solve-engine/packages	Built-in packages and their configuration
solve-engine/constants	Configuration defaults (DEFAULT_CONFIG, ConfigManager) and ENGINE_VERSION
solve-engine/errors	EngineError, the structured error type a failure throws, its taxonomy, and the result type
solve-engine/worker	Off-main-thread evaluation: the worker proxy, transports and result DTO
solve-engine/engine-worker	The worker entry the engine’s own offloaded compile and execute pools run, started by a host through setEngineWorkerFactory. Its own bundle, carrying every built-in package
solve-engine/testing	A test kit for package authors: createTestEngine, expectExpression, expectPackage
solve-engine/temporal	The Temporal calendar backend: createTemporalCalendar, passed as an engine’s calendar option

Advanced

Also public, but they expose pipeline internals. Reach for them when writing a package or building tooling.

Entry	Contains
solve-engine/lexer	Tokeniser and vocabulary types
solve-engine/parser	Parselets, binding powers, bytecode builder
solve-engine/normalizer	Phrase fusion and normalisation rules
solve-engine/resolvers	Async resolver contracts
solve-engine/utilities	Shared helpers
solve-engine/uom	Unit definitions and conversion
solve-engine/services	Data query plumbing

Internal

Not exported and not covered by semantic versioning: telemetry, caching, diagnostics, the internal compile/execute worker managers, and internal types. (The public solve-engine/worker entry above is the supported way to move evaluation off the main thread.) If you find yourself needing one of these, that is worth raising as an issue, because it usually means a public entry point is missing something.
