xian-tech-runtime-types

Shared deterministic runtime types for the Xian stack.

decimal.py: fixed-precision ContractingDecimal and decimal bounds
time.py: deterministic Datetime and Timedelta
collections.py: deterministic set and frozenset implementations
encoding.py: JSON encoding/decoding for runtime storage values

These types are used by xian-contracting and other packages that need the same deterministic value semantics without importing the full contract runtime.

The encoder and convert_dict normalize nested lists and dictionaries recursively. Large integers use __big_int__ at every depth; booleans retain their JSON type.

Validation

The package is covered by the root test suite:

uv run pytest -q tests/unit/test_decimal.py tests/unit/test_datetime.py \
  tests/unit/test_timedelta.py tests/unit/test_contracting_collections.py \
  tests/unit/test_encode.py
