 - P03: `PaneGroup` leaves a gone or last pane and logs (`split` returns `Option`); a stale split path sets nothing; `SplitPane` splits evenly when sizes lag or fail, seeds by the owner's raw sizes, and drops a drag over another pane count; masonry sorts with `total_cmp`. Kept: dock ids (panels never leave), one-value contracts, pane-id overflow, workspace JSON. Review: 2 rounds.
 - P04: no change. Kept: splash progress and column count (caller contracts), the objc class under `Once`, `Tray::pick` (items fixed at creation). Review: 1 round.
 - P05: a `SegmentedControl` whose choice left its segments marks none; the cause, `motion::slide`, logs and returns no marker (P11 inherits it). Kept: one-value contracts (group and quick-action counts, toggle label or icon, share payload). Review: 1 round.
+- P06: a root path shows whole; `TextInput::select` logs a range past the text or inside a character; the text element logs shaping and paint faults; a unit gone from its list logs; cron runs in the system zone go through `datetime`. Kept: empty choice lists (the owner disables, as AGENTS.md says), one-value contracts, facts by construction. Review: 2 rounds.
