The gallery cursored on COALESCE(post.post_date, image_record.created_at) across the Post outer join — an expression spanning two tables that no index can serve, so every /scroll sorted a large slice of the library (and the old frontend fired ten serially). Materialize it: - image_record.effective_date column + ix_image_record_effective_date (effective_date DESC, id DESC); alembic 0035 backfills COALESCE(primary post's post_date, created_at) for existing rows. - gallery_service._effective_date_col() now returns the column, so scroll / timeline / jump / neighbors all order off the index instead of re-deriving the COALESCE. _neighbors reads record.effective_date directly (drops an extra Post lookup). - importer._apply_sidecar maintains it: when a primary post with a date is linked, effective_date = post.post_date; plain inserts keep the created_at-equivalent server default. Tests: sidecar import asserts effective_date == post.post_date; gallery ordering/timeline/jump test seeds set effective_date alongside created_at.
