For distinct primary and secondary package names, this change leaves the canonical entries as the sole owners and makes the aliases non-owning, which fixes the direct ClearServices() double deletion. One PR-scoped correctness regression and one missing proof remain:

• If the configured secondary package equals the primary package, the non-owning assignments overwrite the only owning entries, so the service and method statuses leak.
• The Cloud lifecycle test still clears the secondary package specifically to avoid the reported destructor crash, so no runtime test executes this ownership branch.

Critical checkpoint conclusions:

• Goal and behavior: the collision-free shutdown path is improved, but the equal-package configuration introduced in the inline finding violates the ownership contract.
• Scope and clarity: this is a focused branch-4.0 backport of the BRPC patch change; the method and service ownership changes are symmetric and no unrelated source change is included.
• Lifecycle and error handling: distinct-key ClearServices() is safe under the new ownership flags. The equal-key overwrite is the remaining PR-scoped lifecycle defect. Removal/rollback stale aliases were examined but are unchanged from the base patch and were excluded from the inline set.
• Configuration and compatibility: no wire, protobuf, storage, or persistence format changes apply. The unrestricted secondary_package_name setting exposes the equal-package edge.
• Concurrency, performance, and observability: the changed ownership fields are consumed by deletion guards; no new race, lock, hot-path, or observability regression was substantiated.
• Persistence, transactions, data writes, and FE/BE propagation are not applicable to this one-file third-party ownership delta.
• Validation: git diff --check passes. This runner has no thirdparty/installed tree or protoc, and the review contract forbids builds, so local validation was static. At the final sweep, GitHub reported Cloud UT and both macOS third-party builds successful; the Linux third-party build was still running, BE UT reported failure, and several regressions were pending. Cloud UT does not exercise the changed branch because the test forces the option empty.
• User focus: no additional focus was provided; the full PR was reviewed.

Review completion: the sole changed file and its BRPC/Cloud upstream and downstream paths were reviewed through three rounds. Every candidate was accepted, deduplicated, or dismissed with concrete base-vs-head evidence, and all normal and risk-focused agents returned NO_NEW_VALUABLE_FINDINGS for the final two-comment set on head c5074691e385773ad0206f2737584c92c7d730b6.
