MCore bump auto-fix status for dev:

Classification: MCore broke Bridge
Evidence: The latest Linear Daily MCore Bump Journal entry MB-479 from 2026-06-02 identifies #4111 as the current main / mcore-dev bump. PR #4111 updates MCore dev from 3f6a2ed844373ef0ed6c0e6dbac58a431d088dcb to 1fe78252e9690505a04759f56b6cbb35861fcb37; the MCore compare is diverged, ahead_by=476, behind_by=148, with final compared commit 1fe78252e9690505a04759f56b6cbb35861fcb37 from 2026-05-29. On 2026-06-02, Installation Test job 79053866764 fails at src/megatron/bridge/utils/common_utils.py:25 with ImportError: cannot import name 'safe_get_world_size' from 'megatron.core._rank_utils'. Release build-wheel job 79053924536 and CICD NeMo jobs Launch_Unit_Tests_Core 79067637936 and Launch_Unit_Tests_Diffusion 79067638043 fail the same import during wheel validation or unit-test collection.
Fix PR: #4094. No new fix PR opened because this existing open PR covers the same dev target failure.
Guards: none added by this worker. Existing PR #4094 migrates Bridge off the removed MCore helper surfaces instead of adding a new compatibility guard.
Validation: read-only validation completed on 2026-06-02 07:05 PDT: gh pr view 4111, gh pr diff 4111 --name-only, gh pr checks 4111, gh run list --branch pull-request/4111, Actions job-log API downloads for jobs 79053866764, 79053924536, 79067637936, and 79067638043, and MCore compare 3f6a2ed844373ef0ed6c0e6dbac58a431d088dcb...1fe78252e9690505a04759f56b6cbb35861fcb37. Existing fix PR #4094 has passed Installation Test, Build/validate/release, Launch_Unit_Tests_Core, Launch_Unit_Tests_Diffusion, and Nemo_CICD_Test from 2026-05-31 to 2026-06-01; only codecov/patch is failing. No CW interactive validation was run by this worker because no new code branch was created.
Next action: review and merge #4094, then rerun #4111 or wait for the next main / mcore-dev automated bump. This worker is waiting for the existing fix PR rather than opening a duplicate fix.
