Migration: Divider Dual Rename — type/orientation Swap

Context

The Divider block has a dual rename where both type and orientation change meaning:

• Old type (direction: horizontal/vertical) → becomes orientation
• Old orientation (text position: left/center/right) → becomes titlePlacement with value mapping

This is tricky because both properties exist and their meanings swap. A naive rename would break the config.

What to Do

For each Divider block, apply both renames simultaneously:

Important: Apply both changes in one pass to avoid the intermediate state where type is renamed to orientation and then conflicts with the existing orientation.

Files to Check

Glob: **/*.{yaml,yml} Grep: type: Divider

Examples

Before — horizontal divider with left text

- id: section_divider
  type: Divider
  properties:
    type: horizontal
    orientation: left
    children: Section Title

After

- id: section_divider
  type: Divider
  properties:
    orientation: horizontal
    titlePlacement: start
    children: Section Title

Before — vertical divider (no orientation)

- id: vert_divider
  type: Divider
  properties:
    type: vertical

After

- id: vert_divider
  type: Divider
  properties:
    orientation: vertical

Before — only orientation set

- id: centered_divider
  type: Divider
  properties:
    orientation: center
    children: OR

After

- id: centered_divider
  type: Divider
  properties:
    titlePlacement: center
    children: OR

Edge Cases

• A Divider may have only type, only orientation, or both — handle each case
• type: on a Divider is NOT the block-level type: key (which identifies the component). The block-level type: Divider stays unchanged. Only rename type: that is under properties:
• If type or orientation use operator expressions, rename the key but flag the value for manual review
• Verify each Divider after transformation — the dual swap is error-prone

Verification

Search for Divider blocks and check for old property names:

grep -rn 'type: Divider' --include='*.yaml' --include='*.yml' . -A 10 | grep -E '^\s+(type|orientation):'

Under Divider properties, type: should not appear (replaced by orientation:), and orientation: with values left/right should not appear (replaced by titlePlacement:).
