SEMQ TypeScript API

SEMQ: deterministic symbolic encoding of float32 vectors, for browsers and Node, over the shared C core compiled to WebAssembly.

Five types and one service, backed by a core that owns every rule:

• CodecConfig: the rule (quant, phase or orbit).
• Codec: encodes unit-norm float32 vectors into an Encoding.
• Encoding: ids, canonical rows, a manifest and two identities; toBytes/fromBytes, concat and diff.
• Diff: added, removed and changed ids with hamming distances.
• Floor: the envelope of variation observed in null diffs of one reference, with asDict() and Floor.fromDict() for its report form.
• BuildInfo from buildInfo.

Errors: InvalidInput, Incompatible, FormatError, IntegrityError, Unsupported, Native. Out of memory is a RangeError.

Loading the wasm module is the one asynchronous step. await Codec.create(config) performs it; so does load, for code that needs CodecConfig, Encoding.fromBytes or Floor before it has a Codec. Everything else is synchronous and raises Native when called before the runtime is loaded.
