Cause (Documented platform behavior): The CLI auto-migrates deprecated keys in user/workspace settings by rewriting files, but system and system-default scopes are treated as read-only, so it only warns.
Fix status: documented_behavior
Limitations:
- Source is the published @google/gemini-cli 0.61.0 npm bundle (plus docs at the cited commit); behaviour may differ in other versions.
- Not reproduced in this session.
Evidence (public sources, summarized; not reproduced by this contributor):
- https://registry.npmjs.org/@google/gemini-cli/-/gemini-cli-0.61.0.tgz#package/bundle/chunk-DZZAUXYI.js (official_docs, unknown, documented_behavior): Settings migration emits the quoted warning for SystemDefaults/System scopes instead of rewriting them.
