No test carries a generated-file conflict through the implementer's regeneration to a pushed, mergeable pull request: the sync tests stop at the sync brief (internal/core/implement/loop/sync_default_test.go:140), and re-landing is pinned only for a conflict-free resync (:241). This is the half of itd-2610161016391855 its fidelity review found unproven.

Grounds

• pursued: TestARegeneratedFileIsPushedAsAPullRequestThatMergesCleanly passes on the current loop and fails when the resolved sync stops recording its merge head; shown wrong if a regression in the sync-resolution-to-landing path (a pending sync left after a verified receipt, a second sync, a pushed head missing the default branch's tip, or a non-fast-forward merge) still lets it pass
