The ChatGPT extension now expresses registry reads through an explicit projectless RegistryClient. Registry requests no longer require placeholder endpoint, project ID, or credential values. Operation names and request/result decoders come from the generated SDK operation catalog, and the client uses the existing projectless ServeSession and SDK error classes.

The rekey regressions hold real workers in the existing history fixture while inspecting transferred work. This prevents a worker from consuming a request before its queue-count assertion. Dropped-rekey and readmission handoffs retain exact counts, request/frontier identities, and wake routes. The readmission change is the same validated patch carried from #4391; cancellation starts before releasing its held history pass.

Verification through Bazel:

• Before the latest master update, the original rekey regression and all 14 registry lifecycle tests passed, covering dropped joins, retirement, readmission, cancellation, panic recovery, and handoffs. Strict Clippy passed for the session-runtime unit-test target.
• The readmission patch carried from build(bazel): update to 9.3.1 and reuse eval process ownership #4391 passed its focused native test (1 case, 155 filtered) and strict Clippy under Bazel 9.3.1 there. Those identical checks were not duplicated in this lane.
• Pinned formatting, diff checks, and the commit hook passed after integration. Updated from master before pushing the combined changes.

Full CI on the combined head is pending, including the extension's native daemon journeys; prior-head green checks do not establish readiness for this head.

Cross-referenced #4225. The projectless RegistryClient removes the fake project boundary for registry operations, and I found no new concrete correctness defect in that change. It remains a scoped first step: project operations and session ownership are unchanged, while #4225 also requires one documented client/session ownership path, deterministic restart/shutdown behavior, cancellation/concurrent-acquisition conformance, and removal of superseded ownership code.

I changed the PR body's Fixes #4225 to Refs #4225 so merging this slice does not close the remaining boundary work. Review here was source/generated-contract comparison; real-daemon conformance was not run locally.
