# `PhoenixKit.Migrations.Postgres.V134`
[🔗](https://github.com/BeamLabEU/phoenix_kit/blob/v1.7.165/lib/phoenix_kit/migrations/postgres/v134.ex#L1)

V134: folder-header customization columns on `phoenix_kit_media_folders`.

Adds the fields backing the Media browser's folder hero header / "Edit header"
panel:

  * `cover_file_uuid UUID` — background image (a normal uploaded file living in
    the folder, excluded from its visible listing). FK to `phoenix_kit_files`
    with `ON DELETE SET NULL` so deleting the file self-heals the reference.
  * `logo_file_uuid UUID` — icon/logo shown in the header (same FK).
  * `header_size TEXT NOT NULL DEFAULT 'medium'` — header height: small /
    medium / large.
  * `header_show_title`, `header_show_icon`, `header_show_creator`,
    `header_show_date`, `header_show_file_count`, `header_show_description`,
    `header_show_background` BOOLEAN — per-folder visibility toggles for each
    header element (default on). Creator / date / file-count are independent
    so users can show just the pieces they want.

All nullable / defaulted, so existing folders render the header as before.
Idempotent: `ADD COLUMN IF NOT EXISTS` plus guarded `ADD CONSTRAINT`, safe to
re-run.
