 - P20: a hex selection off the bytes and a stack frame past the stack select none; a flame focus keeps what the profile holds; the timeline's wheel reports only finite, positive ranges from finite factors; a dump's last byte must have an address; flame paints log. Kept: disassembly patterns, `zoomed`'s contract. Review: 3 rounds.
 - P21: block editor listeners painted for a block, field, cell or kind since gone log and change nothing, a dropped picture drag leaves undo alone; a visual block press or edit over text the owner replaced is dropped; nested images parse; a version or find hit past its list selects none. Review: 4 rounds.
 - P22: annotations and suggestions outside their text log and stay out, picks and decisions keeping the owner's index; `accept` returns `Option`; a gone pick, active thread or followed peer logs; yours at no count comes off; a masked field clamps a stale offset, so remote cursors and selections draw. Kept: a thread's comments, presence max, one list's order, empty marks, constant role and mode tables. Review: 3 rounds.
+- P23: a branch version past its total logs and shows a dash, its arrows off; a parameter outside its range logs and pegs; a passage's matches outside it log and stay out. Kept: one-value contracts (progress, scores, shapes, peaks, levels, limits, prices, capacity, format, hour), the composer's trigger rows and stream reveal by construction; `places` skips zero, so `decimals` meets no zero step.
