Closing as duplicate: W2.3 Bucket E already squash-merged to main via #4078 (e1dfb016, 2026-05-31). This draft was auto-opened on session/loyal-badger-289-w2.3-bucket-e after merge; no additional diff vs current main. Five GateStep CiUpsertStep rows + full ci_pipeline_step_ids_shadow bijection are on main.

[briansrls]

Verified against current main: Bucket E (ci_upsert_structural_v2_compile + four sibling gate rows, ci_upsert_steps_full_in_scope_step_ids bijection) is present on main @ e1dfb016 via merged #4078. This PR’s branch (a2b51b1) adds no net change atop that merge base.

Disposition: remain closed as duplicate — do not mark ready or merge. No fix commit warranted.
