Findings the reviewer chose to accept rather than block on.

Source	Rule	Reason	Accepted by	When
provenance	missing-githead	AI (provenance): Established JupyterLab ecosystem package with strong publisher track record; missing gitHead is a process concern, not a security indicator for this package.	ai	2026/04/24
provenance	publisher-changed	AI (provenance): Publisher change to jupyterlab-release-bot is the documented JupyterLab automated release process; this bot has 3583 approved packages and 0 rejections. Stable for this package.	ai	2026/04/24
maintainer-change	maintainer-added	AI (maintainer-change): jupyterlab-release-bot is the official JupyterLab release automation account; its addition as maintainer is expected and benign for all Lumino packages.	ai	2026/04/24
