Compose posts reach the command history; the pane's tab chord becomes findable - #34

⌃S reached the session directly and skipped OnCommandEntered, which holds the one seam that adds a history entry — so a composed post was echoed and alias-expanded (both free from SendUserInputAsync) and never recorded. SendComposed's own doc had claimed all three for as long as the composer existed. It keeps going direct: OnCommandEntered is the command *line's* seam and clears that window's bar draft, moves the unsent marker and owns the /web, /graphics and /triggers branches. It records the entry itself instead — the built line rather than the buffer, since history holds sendable commands, and through InputHistory.Add so a post carrying a connect line meets the same secret gate.

⌃N has cycled the focused pane's tab strip for as long as panes have held more than one window, and it was named on F4 and nowhere else. It is now a ⌃P entry (layout:next-tab) and a status-row segment (⌃N tab, shown while the focused pane has a second tab). The chord stays ⌃N because the familiar spellings do not arrive, measured at a raw reader rather than assumed: ⌃Tab is 09, byte-identical to Tab; ⌃⇧Tab is CSI Z, byte-identical to ⇧Tab; ⌥Tab is ESC + a control byte and so arrives as two key events, on a chord the compositor takes anyway. Listing a key obliges it to answer. NextWindow returned in silence on a single-tab pane — indistinguishable from a dead key — and now refuses out loud, beside the pane cycle's own wording. Every surface says tab rather than window; F4 and --help said window while the rest said tab, and ⌥N already owns the window noun. FocusHints is generated from a segment list instead of eight hand-written ladders, with reading order and drop order kept separate so the existing pane · size · line row is unchanged cell for cell.

The paragraph stated the reading order as pane · size · line and explained only size's priority, while the code inserts ⌃N tab between the pane and size segments at rank 1. CLAUDE.md carried the reasoning; the doc a reader of the method actually sees did not.

The terminal's own selection cannot do this job — UrlDetector's argument one layer over. Under ?1003, which this client needs for the wheel, tab and rail clicks and pane drag-and-drop, a plain drag belongs to the application; the emulator's escape hatch selects a terminal *row*, which on a vertical split crosses the divider into another pane's output, and since a pane is narrower than the row a logical line wraps and comes back with newlines injected at the wrap points. Almost all of it is the framework's, shipped in the pinned 2.5.14 and off by default: drag, double-click word, triple-click line, drag-autoscroll and a soft-wrap-aware copy. What had to be ours is the colour, the clipboard, and what happens when the buffer moves. - WorkspacePalette.SelectionBand/SelectionInk: one pair per theme, since a selection is not an identity or a focus fact. ReadingPlane pushed further in the direction of travel, leaned toward Theme.Prompt. Held to a fill floor against all fourteen planes and the ink to Contrast.Floor on the band — the highlight replaces the world's foreground too, so that ink is what all selected output is read in. - The clipboard writer is caller-supplied and null by default, the save:/logRoot:/openUrl: family. It also buys one copy path: the framework's ⌃C writes through a static helper no caller can substitute, so a test run would have replaced the developer's real clipboard. - ⌃C is claimed in the main window's key chain, not in AppShortcuts — a global shortcut would take it from the composer's editor as well. - RepaintPane drops any selection: chrome rows go in and out mid-buffer and a selection anchored to display rows would highlight text nobody dragged. - NewPaneControl is now the one place a pane control is made. Enabling selection on PaneContentFor alone left the main window unable to select anything, because that control is built in the constructor. SimulatePaneDrag is the test seam (the framework routes mouse only inside Run()), and the new `selection` view is the frame — in FrameContrastTests' list, because a colour nothing renders is a colour nobody checks.

… move Two defects from review, both real and both confirmed by a test that failed first. The copy asked the *focused pane*. Pane selection moves on ⌃arrows, ⌃O and a tab click, and a press in a pane's body moves none of them — so a drag in the pane beside the focused one left ⌃C looking elsewhere and reporting "nothing selected", which reads as a feature that does not work. It asks the window's SelectionManager now, which owns the one active selection and clears the previous owner when a new one starts. That also retires the special case for a frozen pane: one selection, one owner. The clear was at RepaintPane, which is not the only thing that re-feeds a pane — BuildFrozenContent feeds both halves and ToggleFreeze's thaw branch pours the whole buffer back. It moves to FeedRange, the one function that actually replaces a control's content. MarkupControl.SetContent does not clear a selection; only its append path does, so this cannot be left to the framework. The thaw is the case with teeth: freezing leaves the live control empty so a stale anchor yields nothing, while after a thaw the rows exist again and the new test copied "The Grand Plaza…" before the fix. PaneWindows() is added because the first cut of the non-focused-pane test passed a *pane* id to a seam that takes a *window* id and selected nothing — indistinguishable from the bug it was written to catch.

fix(compose)— a post you wrote is a post you can recallThe F1 composer's ⌃S called the session's send directly and skipped
OnCommandEntered, which holds the one seam in the client that adds a history entry. A composed post was therefore echoed and alias-expanded — both free fromSendUserInputAsync— and never recorded, so ⌥↑ and ⌃R could not reach it.SendComposed's own doc had claimed all three for as long as the composer existed.It is not consistency-by-design. The rule elsewhere is history records what was entered on a command line, not what was sent:
/webis in it and a macro is not, and the auto-login's exclusion is deliberate and pinned. A composed post is a command the user just wrote, and it was the only user-authored command in this client with no recall route at all.It keeps going direct rather than being routed through
OnCommandEntered, which is the command line's seam: that also clears the window's bar draft, moves the unsent marker and owns the/web,/graphicsand/triggersbranches, none of which belong to a post written elsewhere. It records the entry itself instead — the built line rather than the buffer, since history holds sendable commands and a recalled entry lands on a one-command bar — and throughInputHistory.Add, so a post carrying a connect line meets the same secret gate.Paste into the composer was checked and is fine: it reaches
