🚀 Thanks for opening this pull request! We appreciate your effort in improving the project. Please let us know once your pull request is ready for review. Tip
Note Please respond to review comments from AI agents just like you would to comments from a human reviewer. Let the reviewer resolve their own comments, unless they have reviewed and accepted your commit, or agreed with your explanation for why the feedback was incorrect. Caution Pull requests must be written using an AI agent with human supervision. Pull requests written entirely by a human will likely be rejected, because of lower code quality, higher review effort and the higher risk of introducing bugs. Please note that AI review comments on this pull request alone do not satisfy this requirement. Our CI and AI review are safeguards, not development tools. If many issues are flagged, rethink your development approach. Invest more effort in planning and design rather than using review cycles to fix low-quality code. |

@coderabbitai Addressed in e5d8d93, with one part of the suggestion adopted and one declined. Replying here because the comment was outside the diff range and has no inline thread. Adopted: a Declined: the suggestion for the branch at What was done instead: never place a non-string in the query, and where no application scope is available, skip the cleanup rather than run it unscoped.
This resolves the correctness concern: no query is ever built from an operation object, so there is no query that silently matches nothing. Ordinary deduplication is unchanged and still removes stale rows, which is verified by an existing spec in the block. Skipping is limited to the case where the request both changes the device token and unsets Verified on MongoDB 8.0.4 and PostgreSQL: 11 specs in the new block and 181 related specs across ParseInstallation, InstallationsRouter, InstallationDedup, Parse.Push, PushController, PushWorker, AudienceRouter, Idempotency and ParseSession, 0 failures on both. Lint clean. |

@coderabbitai Applied the assertion tightening in d27ed9d. The test now asserts the full installation set rather than a single membership check, matching the sibling test, so the "cleanup is skipped" claim is fully provable. All review findings on this PR are now addressed:
