fix(scancode): use matched_text only for unknown-spdx - #319
Conversation
prefer_spdx_declarations should only filter declaration matches; known licenses must keep ScanCode license_expression so HTML trailers like </p> are not treated as part of the license id.

In `@src/fosslight_source/_parsing_scancode_file_item.py`:
- Line 660: Update the non-preferred license-expression handling around
found_lic_list so resolving unknown-spdx replaces only that token and preserves
known tokens such as MIT alongside the declared Apache-2.0 value. Retain the
existing token-level resolution behavior and add a regression case covering a
mixed unknown-spdx AND mit expression.

Replace only unknown-spdx tokens when known licenses are present, and build comments from detected_license_expression so prefer_spdx filtering does not hide ScanCode aggregate findings.
Record body matches removed by prefer_spdx as Detected: expressions, preferring license_expression_spdx and deduping values covered by another expression's AND/OR tokens.
