InlinePhotoBlock QA Audit

LetterBodyComposer + InlinePhotoBlock — all 5 wrap modes, keyboard handlers, floating isolation

✅ All 12 tests pass

Logic Unit Tests — pure function simulation

✅

insertBlock(behind): existing flow blocks are NOT shifted

✅

insertBlock(inline): existing flow blocks at/after position ARE shifted

✅

insertBlock(inline): behind blocks are never shifted

✅

removeBlock(behind): removes only that block, no re-indexing of others

✅

removeBlock(inline): re-indexes blocks after the removed position

✅

Enter key: behind/front blocks are NOT shifted by split

✅

Backspace: block at merged paragraph index removed, floating preserved

✅

moveBlockTo: returns early for behind/front blocks

✅

blocksAfter: behind/front blocks excluded from slot rendering

✅

New inline block defaults: wrap_mode=inline, corner_radius=true

✅

New behind block: opacity=0.45 by default

✅

New front block: opacity=1 by default

What these tests verify:

insertBlock floating — behind/front blocks never cause flow re-indexing
insertBlock flow — only flow blocks at/after position are shifted +1
removeBlock floating — floating blocks removed cleanly, no position side-effects
removeBlock flow — blocks after removed position shift -1, floats untouched
Enter key — splits text, shifts only flow blocks > idx
Backspace key — merges text, removes flow block at idx, never removes floats
moveBlockTo — early-returns for floating blocks
blocksAfter — floating blocks excluded from flow slot rendering
Defaults — opacity 0.45 for behind, 1.0 for front
