📝 Walkthrough

Walkthrough

The pull request adds an AI contribution policy and updates the shared configuration workflow to synchronize AI_POLICY.md, .clang-tidy, and cliff.toml.

Changes

AI contribution policy

Layer / File(s)	Summary
Policy definition AI_POLICY.md	Defines requirements for AI disclosure, human review, accountability, contribution standards, autonomous agent restrictions, text labeling, enforcement, and Assisted-by attribution.

Shared configuration synchronization

Layer / File(s)	Summary
Config synchronization list .github/workflows/update-shared-configs.yml	Adds AI_POLICY.md, .clang-tidy, and cliff.toml to the config-sync file list.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: ⚪ Minimal · up to 5eb7b

The new policy leaves the required AI-use disclosure location and marker unspecified, creating a small compliance and review-consistency follow-up. This is localized documentation risk and does not block merging after normal checks and owner awareness.

Define one disclosure format.

The policy requires contributors to disclose AI use and mark AI-generated text, but it does not define the required location or marker. Add one concrete example so reviewers can check compliance consistently.

Example clarification

- - Disclose that AI was used and name the tool/model.
+ - In the pull request or issue description, disclose AI use with
+   `AI-assisted: <tool>:<model>`.
...
- - Clearly mark AI text in descriptions and issues.
+ - Prefix AI-generated text with the documented marker.
