LICENSE (1)

178-201: Consider adding copyright headers to source files.

The LICENSE file provides the legal framework, but Apache 2.0 licensing best practice recommends that each source file include a copyright notice and license header. This ensures clear provenance and licensing at the file level, particularly important for derivative works and distribution.

Verify that:

• Source files include proper copyright notices (e.g., Copyright [year] [owner])
• Files reference the LICENSE file or include abbreviated Apache 2.0 boilerplate headers
• Any third-party or contributed code is properly attributed

LICENSE (1)

1-201: LICENSE file correctly contains the canonical Apache License Version 2.0 text.

The file has 201 lines of text and is composed of the header (lines 1-3), the terms and conditions (lines 5-176) and the appendix (lines 178-201). All sections are present and match the canonical form from https://www.apache.org/licenses/LICENSE-2.0.txt.

Additionally, a NOTICE file should be present in the same directory, and each original source document should include a short license header at the top.
