TheFuzz facade external-source audit

This audit covers src/stride_align/thefuzz/, its focused tests, and the generic-sequence extension to the native partial-ratio dispatcher. Native stride-align code remains Apache-2.0; the two compatibility references below are MIT-licensed and Apache-2.0 compatible. Their license texts are retained in NOTICE, which is included in wheel metadata.

TheFuzz 0.22.1

• Source: https://github.com/seatgeek/thefuzz, release 0.22.1
• License: MIT, Copyright (c) 2014 SeatGeek
• Used for: the public module/function/signature surface; integer rounding; force_ascii and full_process composition; Unicode aliases; process defaults, tuple shapes, and scorer lowering behavior; dedupe semantics.
• Adaptation: the facade is an independent stride-align-backed adapter, but its compatibility structure and observable legacy conventions are adapted from TheFuzz under the MIT license.
• Runtime dependency: none. TheFuzz is imported only by the optional differential section of tests/test_thefuzz_shim.py.

RapidFuzz 3.14.5

• Source: https://github.com/rapidfuzz/RapidFuzz, release 3.14.5
• License: MIT, Copyright © 2020-present Max Bachmann; Copyright © 2011 Adam Cohen
• Used for: TheFuzz delegates scoring and extraction to RapidFuzz, so its public behavior is part of the compatibility target. The facade retains the generic-sequence normalization convention (single-character strings become code points; other objects use 64-bit hash tokens), whitespace-token behavior, token-set score operation order, and ranking by unrounded scores. RapidFuzz is also an optional black-box differential oracle.
• Adaptation: compatibility adapters are expressed in original Python and dispatch scoring to stride-align's kernels; no RapidFuzz binary or source is shipped. The MIT text is nevertheless retained because source was consulted for these edge-case conventions.
• Runtime dependency: none.

Explicit GPL exclusion

FuzzyWuzzy (github.com/seatgeek/fuzzywuzzy) is GPL-2.0. Its source, tests, fixtures, and expected-output vectors were not read, copied, translated, or used. The facade targets its MIT-licensed successor TheFuzz only. No claim in the API documentation changes that exclusion.
