Navigate logical layers of code changes, visualize relationships, and explore their blast radius. 📝 WalkthroughWalkthroughThe workflows disable persisted checkout credentials, and the commit-check workflow adds a read-only contents permission and pins checkout to a commit. The test suite adds coverage for environment handling, pull request processing, report comments, warnings, and skipped-scope output. ChangesWorkflow checkout credentials

site:docs.github.com REST API issue comments edit delete authenticated user author write access repository
💡 Result:
GitHub’s REST API docs list **Update an issue comment** (`PATCH`) and **Delete an issue comment** (`DELETE`). For fine-grained tokens, both require repository **Issues: write** or **Pull requests: write** permission. ([docs.github.com](https://docs.github.com/en/rest/issues/comments?apiVersion=2022-11-28&utm_source=openai))
The docs establish the token permission requirement, but the cited endpoint text does **not** say that the authenticated user must be the comment’s author, nor does it specify a separate repository “write access” role requirement. Those details aren’t resolved by this source. ([docs.github.com](https://docs.github.com/en/rest/issues/comments?apiVersion=2022-11-28&utm_source=openai))

Restrict managed comments to the authenticated account.
_find_own_comments checks only user.type == "Bot". If another bot posts COMMENT_MARKER, add_pr_comments can treat that comment as its target. If the body matches, the action returns without creating its report. If it differs, the action can attempt to edit the other bot's comment. Apply the authenticated token's login check to both marked and legacy comment selection.

commit-check.yml was the one workflow still referencing checkout by tag. Pin the same v7.0.1 the other workflows use, with the tag in a comment.
Nothing after checkout in commit-check, coverage, test or used-by needs authenticated git (create-pull-request sets up its own auth for its push), so the token is no longer left in .git/config. release.yaml keeps it: that job pushes the re-created tag.
Bring main.py to 100% line and branch coverage (95% before): the debug log of the inputs, the PR number read from the event payload, a missing PyGithub, token or repository, stale report clean-up, an unparsable scope in the report table, the footer without a version, and running the script itself. Also move `if __name__ == "__main__": unittest.main()` to the end of the file. It sat in the middle, so `python main_test.py` ran 158 of the tests, and two of those errored on helpers defined after it.

Require bot authorship for marked comments.
_find_own_comments() applies _is_bot() only to legacy comments. A human-authored comment containing COMMENT_MARKER can be selected, edited, or deleted. Add the regression test and enforce the bot check for marked comments.
