The autonomous PR pipeline that writes those commits landed in-repo, undocumented.

Between 2026-08-05 and 2026-08-07, twelve PRs from @joneba-google and @chadd28 built out tools/caretaker-agent/ in the Gemini CLI repo: a Cloud Run job, Workflows definition and Dockerfile for a PR generator (#28431, commit bde504f2500bd2326fd578c5828476cede9442d8); an iterative bug-fixing state machine and container worker entrypoint (#28433); an environment-config parser, command executor and GitHub client (#28435); an Antigravity agent runner with prompt templates (#28434); a Firestore-backed job store with dual locking (#28432); an LLM triage orchestrator with prompt hill-climbing (#28345, #28524); a triage evaluation framework with a judge runner and golden-issue collection (#28530, #28532); a Pub/Sub ready-for-code topic publisher (#28588); and a GCP deployment script (#28529). Google is running the loop against its own issue tracker -- earlier work in the same series (#28352) sanitizes and wraps GitHub issue titles in untrusted_context before feeding them to the triage model. No entry for any of this exists in docs/, README.md, or ROADMAP.md: grep -rli 'caretaker|SSR agent|pr-generator' docs/ README.md ROADMAP.md matches only the auto-generated changelog files.

Channel: tagged-release. Ancestry: git tag --contains bde504f25 -> v0.55.1 (stable). Same for cf22ac7e8 and the rest of the 2026-08-05..08-07 batch. Nuance: this code sits under tools/caretaker-agent/, and git show v0.55.1:package.json gives workspaces: ["packages/*"] -- so it is inside the stable tag's tree but is not part of the published npm package.

Operator consequence: Observe -- this is the mechanism, not the product. Nothing here ships in @google/gemini-cli, so it changes no runtime behaviour. What it changes is what a commit on this repo means: from 2026-08-14 the same pipeline began landing fixes on main. If you maintain an adapter, a fork, or a security posture that assumes human authorship of upstream changes, that assumption expired in this window, and there is no upstream documentation to tell you so.
