iOS: render terminal full height and pin its bottom to the composer bar - #10594
Merged

Conversation
New contract for WS-detail keyboard handling: opening or closing the keyboard emits no capacity report, keeps the natural grid, and leaves the render rect untouched in surface coordinates. The old design resized the grid per keyboard toggle (a Mac round-trip), producing the 'terminal pushed down, then resized to full' dismissal glitch. Red on current main: keyboard toggles emit smaller/larger capacity reports and move the render. The stale-echo and dropped-echo coverage now drives grid renegotiation through the composer band, which remains a real grid input. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
… bar The WS-detail keyboard glitch (terminal pushed down before resizing to full on dismissal) came from resizing the grid per keyboard toggle: the UIKit keyboard animation and the async grid renegotiation (capacity report -> daemon echo -> reflow) ran on different timelines, and a pile of machinery (defer-shrink, provisional pins, cursor-absorb math, presentation rebasing, settle folds) existed to mask the gap. Delete the cause instead of masking it: - The keyboard is no longer a grid input. terminalContainerSize drops the keyboardHeight parameter, so the grid keeps its keyboard-down size; keyboard toggles run no set_size, emit no capacity report, and no longer reflow the shared PTY (the Mac terminal stops resizing when the phone keyboard toggles). - GhosttySurfaceHostView pins the full-height render with one constraint: renderWrapper.bottom == dock.top + steady chrome reservation. Keyboard motion is a single animated layout pass moving the dock; the render rides it and the top rows clip behind the screen top. Keyboard-down layout is byte-identical to before. - Dock seat authority: UIKeyboardLayoutGuide where it works (chrome visible, non-iOS-27), the plain bottom constraint on iOS 27 and while the chrome is hidden (the guide's safe-area fallback would float the hidden dock 34pt above the screen bottom). - Deleted: wrapper transform + presentation rebasing + settle fold, keyboardPresentationTransitionActive freezes, deferShrinkResize, provisional render pins, cursor-absorb math, stale-live viewport clamps, renderPinnedBottomEdge, drawableContainerSize. - Dock frames in the viewport snapshot are now keyboard-invariant surface coordinates (the dock always sits at the viewport bottom there), and the composer dock probe emits keyboardDockTargetTop on the same basis.

While the terminal content bottom fits above the composer bar, the terminal stays top-pinned under the navigation bar and the keyboard covers only blank rows; as content grows the render transitions continuously into the full bottom-pin so the newest rows ride the composer bar. This kills the post-clear regression where a top-anchored cursor slid behind the screen top for no reason. Mechanics: the host wrapper constraint gains a slack term — renderWrapper.bottom == dock.top + steadyChromeReservation + slack, slack = min(blankBelowContent, keyboardIntrusion) — retargeted with the keyboard's own animation curve on transitions and followed per-frame by the display link while a keyboard is up (content written under the keyboard shrinks the slack row by row). blankBelowContent is the cursor bottom proxy from ghostty_surface_ime_point; alternate-screen apps report nil (a TUI's cursor says nothing about safe-to-cover rows) and keep the plain bottom-pin, wired from the shell store's isAlternateScreen through the representable. The dock seam contract becomes gap == keyboardSlack (still zero whenever content reaches the composer bar); the probe emits keyboardSlack and assertTerminalPresentationPinnedToDock asserts the new equality. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…k seat Two dogfood findings on the kbfull build: 1. Claude Code draws UI rows BELOW the cursor (input-box border, shortcut hints), so the cursor-row proxy let the blank-space absorption cover real content. Content bottom is now measured from the rendered viewport text (last non-whitespace row) on the serial output queue — same lock discipline and throttling as the DEBUG accessibility read — with the cursor row kept only as a lower bound (it can sit on a blank line below the last text). Only the row count crosses to main. 2. The terminal frame visibly travelled on keyboard toggles even when the slack cancels the whole intrusion (short content should not move at all). Root cause: two animation authorities — UIKeyboardLayoutGuide animated the dock inside UIKit's own transaction while the slack retarget animated in a second one. The dock seat is now notification- driven on every OS version: both constants retarget in ONE animated pass, so a full-slack toggle changes the wrapper frame by exactly zero and nothing animates. The guide stays attached as a passive sensor that self-heals the keyboard model after detached transitions (disabled on iOS 27 where the guide can lie at the screen bottom).

The passive guide sensor published mid-animation guide frames into the keyboard model during a notification-driven leg: the guide lags the notification, so a dismissal transiently re-poisoned the model with a partial keyboard height, which reseated both constants mid-flight — the content dipped below its top pin (a spurious top padding) and healed a beat later. Keyboard legs now own both constants until their animation completes (generation-guarded, cleared on window detach): layout passes, safe-area changes, and the display-link absorption follow all stand down while a leg is active — the same transition gate the pre-rebuild design had around its guide reads.

Logs every keyboard leg (target, intrusion, blank, slack, both constants, wrapper frame), leg completion, out-of-leg constant reseats, absorption follows, render-rect moves, keyboard-model writes, and content-row measurement changes to the anchormux debug sink, so a phone repro pinpoints which component moves. Bounded, privacy-safe values only. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The keyboard-visibility model lives on the persistent surface and was only written by keyboard notifications, which the host ignores while detached. Dismissing the keyboard during navigation left the model stuck at visible, so the toolbar keyboard toggle opened a fresh workspace in the wrong state and needed two taps. The layout self-heal now publishes visibility alongside the height: a settled guide at the screen bottom is an authoritative keyboard-down on the sensor OS versions. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ve guide Two reasons the toggle still lied on first open: - The dismiss button was CONSTRUCTED with the hide glyph and label, and setKeyboardShown only fires on visibility transitions, so any surface that opens with the keyboard down kept the wrong default forever. The button now constructs in the show state and the surface re-syncs the glyph from the live model whenever the toolbar installs. - An unconstrained UIKeyboardLayoutGuide never resolves its layoutFrame, which silently turned the passive sensor (including its visibility heal) into a stale-model echo. A hidden zero-sized probe view now rides the guide's top edge so UIKit resolves it; nothing else depends on the probe, so it cannot become a second animation authority. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…ttach The phone trace (kb.* instrumentation) showed the terminal's SwiftUI hosting view still changed size with the keyboard — 836pt down, 802pt up: the terminal expansion ignored .container edges but not .keyboard, so SwiftUI's keyboard avoidance re-shaped the representable by the home-indicator band on every toggle. That resized the grid (61<->58 rows, a shared-PTY renegotiation), leaving a stale one-cell top gap and a transient effective-grid letterbox pin (renderRect@35 in the trace, the user's screenshotted frame) plus remote-reflow row blanking until the round trip settled. mobileTerminalSafeAreaExpansion now also ignores the keyboard safe area, so the hosting view is keyboard-invariant and the grid genuinely never renegotiates on toggles. The trace also showed the resolved guide sensor front-running keyboard notifications (kb.model/kb.reseat before kb.leg): the guide updates a layout pass before the notification arrives, snapping constants without animation. The sensor heal now runs only at window attach — the case it exists for — while attached toggles are notification-owned end to end. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…contract Conflicts in applyGeometryResult resolved to main's side: the stretch-to-fill auto-fit is gone (rendered font is always the user's choice), which supersedes this branch's keyboard-gate edit to that block. The mac-constrained spacing test is rewritten to the letterbox contract plus keyboard invariance (toggles: no report, no font change, no render movement). Ghostty submodule follows main to b17f1726. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…cans Review findings on the merge head: - P1: didMoveToWindow read the keyboard guide before layout resolved it, so a reattach with the keyboard still visible recorded keyboard-hidden and nothing would correct the dock until the next keyboard event. The heal now arms at attach and runs on the first laid-out pass (guide resolved), and any real keyboard notification preempts it. - P2: the content-bottom measurement ran at 4Hz on every output burst even with the keyboard down. It now runs at 1Hz while hidden (a warm value for the next raise) and 4Hz only while a keyboard is up, with a defensive byte cap; the read is viewport-bounded, never scrollback. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Host keyboard animation drives surface layout passes; the unconditional layout-driven geometry sync re-ran ghostty_surface_set_size with an identical container a few times per toggle (visible as duplicate geom lines in the device trace). Bounds are the only layout-borne geometry input — composer band, chrome, safe area, and font changes all schedule their own sync at their mutation sites — so the layout path now syncs only when bounds actually change. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
A detach during a keyboard leg left the wrapper/clip/dock presentation animations running; after reattachment they could override the freshly seated constraint model until they expired. The detach path now removes them, matching the pre-rewrite behavior. The remaining reviewer note about iOS 27 reattach recovery is a pre-existing platform parity gap: main's notification fallback also had no detached-transition recovery on iOS 27, and this PR does not change that population's behavior. Non-27 devices heal from the resolved guide at attach. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
Content written or cleared immediately before a raise (with no output afterwards) could steer the blank-space absorption with a row count up to a second old. Every raise now schedules an immediate measurement on the serialized output queue; the result lands mid-leg and the display-link follow applies any correction at settle. The round-4 reviewer claim that the wrapper constraint is self-referential is a verified false positive: moveBottomDock(to:) reparents the dock container into the HOST before the constraint is created, so the dock-top anchor does not move with the wrapper — device traces show the exact expected constants with a 0.000 seam and no constraint breaks. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
#10518 (keyboard-pinning rebuild) landed on main mid-merge with a competing presentation in the same files. Per Aziz's direction, the synthesis keeps each PR's strength: - kbpp's dock-following spine: notification-only seat authority on every OS, keyboardDidChangeFrame disagreement reseats (0.2s curve for duration-less payloads), and MobileKeyboardFrameTracker healing — height AND visibility — for transitions missed while detached. This replaces this branch's keyboard-guide sensor (and its resolution-probe workaround) outright and also closes the iOS 27 reattach gap the earlier review flagged. - kbfull's terminal presentation: the keyboard-invariant grid and the single wrapper constraint (dock.top + chrome + blank-space slack), with no settle-fold or presentation rebasing. The legacy transform and the rebuilt fold both existed to mask the grid-resize round trip, which no longer exists, so one presentation path remains; the rebuild-revert kill-switch parameters are accepted for call-site compatibility but not consulted, and TerminalKeyboardDockEndpoints/PathSelection stay as dormant kit code with passing tests. The probe reports keyboardDockSource=notification unconditionally; the merged kbpp UITest expecting legacyNotification is updated accordingly. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
CodeRabbit, Greptile, and the local policy check all converged on the setChromeHiddenForTesting wrapper. setChromeHidden is internal now and the behavior test reaches it through @testable import; the shipped seam is gone. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
…sync The grid container reads the window's bottom inset through the surface's fallback resolver, but a window-level inset change neither fires the slid surface's own safeAreaInsetsDidChange nor changes its bounds, so the geometry sync could run against a stale reservation. The host now forwards the resync from its own safe-area handler. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Restore that contract, scoped so iOS <= 26 behavior is untouched: - iOS 27 seats ignore keyboardDidChangeFrame entirely and skip the steady-state tracker heal in layoutSubviews (attach recovery in didMoveToWindow stays - it fixes real workspace-switch wedges and did not exist on the old path). - Interrupted legs rebase from live presentation frames before the next will leg (the #10006 reversal contract), folding the live dock bottom into the seat constraint and re-deriving clip and wrapper models from that edge before stripping animations. - TerminalKeyboardSeatSelection (replacing the stale, unused TerminalKeyboardDockPathSelection) owns the seat decision table: guide seat on iOS <= 26, will-only notification seat on iOS 27+, full-stream notification seat behind the iOS <= 26 kill switch. - CMUX_UITEST_FORCE_IOS27_KEYBOARD_SEAT (DEBUG) runs the exact iOS 27 path on any simulator OS; the dock probe reports keyboardSeatWillOnly.

* test(ios): files chip must stay visible while the keyboard slides the surface Red half of the regression pair. Since #10594 the host slides the full-height render wrapper up so the render bottom rides the composer bar while the keyboard is up; the files chip is anchored to the surface's own top edge, so the slide carries it above the clipped-visible area and the only Files control disappears whenever the keyboard is shown. Also passes the keyboard frame tracker to GhosttySurfaceHostView in the existing full-height pin test: #10687 added the required parameter without updating this call site, and no CI lane compiles cmuxFeatureTests, so the target has been compile-broken since. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ios): pin the files chip to the terminal's visible top while the keyboard is up The chip anchored to the surface's top edge plus safeAreaInsets.top. Since #10594 keyboard motion no longer resizes the surface: the host slides the full-height render wrapper up so the render bottom rides the composer bar, which carries the surface's top edge — and the chip with it — above the clipped-visible area. The only Files control was therefore unreachable whenever the keyboard was shown. The chip now anchors below the highest clipping ancestor's visible top (falling back to safeAreaInsets.top, so resting placement is unchanged and hosts that do not slide are unaffected). A display-link follow re-pins it frame-by-frame during keyboard legs using presentation layers, the same pattern as the dock's absorption follow, with a rest guard so the walk is skipped entirely while nothing can be sliding. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ios): unbreak main-red iOS compile in MobileWorkspaceAggregation #10662 assigns the namespaced group id (MobileWorkspaceGroupPreview.ID) directly to anchorWorkspaceID (MobileWorkspacePreview.ID), which does not compile for the iOS app. Convert through rawValue, the same idiom the group preview initializer already uses for its empty-group fallback. Carried on this branch only to unblock the tagged iOS build; same patch offered to main separately. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ios): unbreak main-red iOS compile in WorkspaceListTableCoordinator Second iOS compile break from #10662: groupActionCapabilities(for:) was declared fileprivate in WorkspaceListTableCoordinator.swift but is called from the +Actions extension file, so the iOS app does not compile. Widen to internal. Carried on this branch only to unblock the tagged iOS build; same patch offered to main separately. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * refactor(ios): anchor the files chip in the host's chrome space instead of following the keyboard Replaces the display-link follow from the previous commit with the same adoption the dock already uses: GhosttySurfaceHostView re-homes the chip container (moveArtifactChip(to:), mirroring moveBottomDock(to:)) and the container is constraint-anchored to the host's safe-area top. The keyboard slides only the render wrapper, never the host, so the chip is keyboard-invariant by construction — no per-frame presentation-layer reads, no visible-top ancestor walk, no drift guards. Hostless surfaces (tests) keep the surface-anchored fallback with identical resting placement. Also fixes the artifact-files popover anchor: it was normalized against the surface's bounds, which drift downward by the slide while the keyboard is up; it now normalizes against the view backing the SwiftUI representable. The regression tests now assert the stronger contract directly: the chip's frame in host coordinates is identical before, during, and after a keyboard seat ride. The earlier slid-clip-ancestor unit test modeled the follower design's topology and is superseded by the host-space invariance test.

…10810) * fix(ios): unbreak the iOS build after the workspace-groups merge Two iOS-only compile errors from #10662 (the Mac target builds; both break every iOS build, so main's iOS lane is red): - MobileWorkspaceAggregation assigns a MobileWorkspaceGroupPreview.ID to anchorWorkspaceID, which is typed MobileWorkspacePreview.ID. Convert through rawValue, the same mapping the type's own initializer uses for exactly this empty-header fallback. - WorkspaceListTableCoordinator.groupActionCapabilities(for:) is fileprivate but called from the context-menu actions extension in WorkspaceListTableCoordinator+Actions.swift, a different file. Make it internal. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * test(ios): iOS 27 will-only keyboard seat must keep a settled dock still Red half of the regression pair. Forces the iOS 27 keyboard seat via CMUX_UITEST_FORCE_IOS27_KEYBOARD_SEAT and asserts the seat reports the will-only contract, a settled composer bar does not move without a will notification, and rapid reversals keep dock and render pinned. Red today because the force env and the will-only seat do not exist: iOS 27 hosts consume the full notification stream, whose non-will frames misreport on that OS and hop the settled dock. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * iOS 27: restore the will-only keyboard seat contract The guide-locked rewrite (#10594/#10687) left iOS 27 on a notification seat that consumes the full keyboard notification stream: did-frame disagreement reseats and steady-state tracker re-derivations. iOS 27 misreports keyboard frames outside the will transaction (#10518 recorded this when it quarantined the rebuilt path away from that OS), so those corrections moved a perfectly settled composer bar after toggles - the regression against the #9958/#10006 path that shipped will-only and was rated perfect in dogfood. Restore that contract, scoped so iOS <= 26 behavior is untouched: - iOS 27 seats ignore keyboardDidChangeFrame entirely and skip the steady-state tracker heal in layoutSubviews (attach recovery in didMoveToWindow stays - it fixes real workspace-switch wedges and did not exist on the old path). - Interrupted legs rebase from live presentation frames before the next will leg (the #10006 reversal contract), folding the live dock bottom into the seat constraint and re-deriving clip and wrapper models from that edge before stripping animations. - TerminalKeyboardSeatSelection (replacing the stale, unused TerminalKeyboardDockPathSelection) owns the seat decision table: guide seat on iOS <= 26, will-only notification seat on iOS 27+, full-stream notification seat behind the iOS <= 26 kill switch. - CMUX_UITEST_FORCE_IOS27_KEYBOARD_SEAT (DEBUG) runs the exact iOS 27 path on any simulator OS; the dock probe reports keyboardSeatWillOnly. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * review: poll the settled dock over a window; document the attach-heal trust tradeoff CodeRabbit findings on #10810: the post-settle stability check now samples the dock edge five times over 1.5s and requires every sample at the settled edge (a transient hop between two single samples could previously pass), and healKeyboardModelFromTracker documents why the will-only seat keeps ATTACH recovery despite the tracker recording did frames iOS 27 can misreport (settled end frame at attach, next will leg corrects a bad record, and skipping recovery wedges the dock after workspace switches mid-transition).

Problem
In the iOS workspace-detail terminal, dismissing the keyboard pushed the terminal down and only then resized it to full height. The grid resized on every keyboard toggle, so the UIKit keyboard animation and the async grid renegotiation (capacity report → daemon echo → remote reflow) ran on different timelines. A pile of machinery (defer-shrink, provisional render pins, cursor-absorb math, presentation-layer rebasing, settle folds) existed only to mask that gap, and the dismissal leg still leaked through.
Fix
Delete the cause instead of masking it: the keyboard is no longer a grid input.
TerminalLetterboxGeometry.terminalContainerSizedrops thekeyboardHeightparameter. The grid always has its keyboard-down size, so a keyboard toggle runs noset_size, emits no capacity report, and no longer reflows the shared PTY — the Mac terminal stops resizing whenever the phone keyboard toggles.GhosttySurfaceHostViewpins the full-height render with one constraint:renderWrapper.bottom == dock.top + steadyChromeReservation. Keyboard motion is a single animated layout pass that moves the dock; the render rides it and the top rows clip behind the screen top. With the keyboard down the constant places the wrapper exactly at its natural position, so steady-state layout is unchanged.UIKeyboardLayoutGuidewhere it works (chrome visible, non-iOS-27); the plain bottom constraint on iOS 27 and while chrome is hidden (the guide's safe-area fallback would float the hidden dock 34pt above the screen bottom).keyboardPresentationTransitionActivefreezes,deferShrinkResize, provisional pins, cursor-absorb math, stale-live viewport clamps,renderPinnedBottomEdge,drawableContainerSize. Net −380 lines of transition machinery.keyboardDockTargetTopon the same basis.Tests (red → green commits)
TerminalViewportSpacingTestsnow asserts keyboard toggles emit no capacity report and leave grid + render untouched; stale-echo and dropped-echo coverage drives renegotiation through the composer band (still a real grid input); the mac-constrained stretch persists through keyboard toggles.TerminalKeyboardFullHeightPinTests(coordinator keyboard-invariance; host-level test that the render bottom stays glued to a riding dock seat with zero reports) and updatedTerminalLetterboxGeometryTests.Blank-space absorption
While the content bottom fits above the composer bar, blank rows absorb the keyboard: the terminal stays top-pinned under the navigation bar and the keyboard covers only empty space (the post-
clearcase). As content grows the render transitions continuously into the full bottom-pin, followed per-frame while the keyboard is up. The slack is a third term on the same wrapper constraint (renderWrapper.bottom == dock.top + chrome + slack,slack = min(blankBelowContent, intrusion)); alternate-screen apps always bottom-pin (a TUI's cursor says nothing about safe-to-cover rows). The dock seam contract isgap == keyboardSlack, exposed in the composer dock probe and asserted by the updated UITest helper.HIG
Checked Virtual keyboards: "Use the keyboard layout guide to make the keyboard feel like an integrated part of your interface" and to "keep important parts of your interface visible while the virtual keyboard is onscreen." The dock (composer bar + toolbar) stays seated on the keyboard layout guide where the OS supports it, and the content that matters (prompt/cursor rows, composer) stays visible above the keyboard. Deliberate deviation: the terminal translates behind the keyboard rather than compressing, because compressing means reflowing a PTY shared with the Mac.

Render the iOS terminal at full height and pin its bottom to the composer bar; keyboard toggles no longer resize the grid or reflow the shared PTY. Dock seating is now notification-driven on all iOS versions with healing for detached transitions, removing the dismissal glitch and keeping layout stable.
Grid is keyboard-invariant: drop keyboard-height sizing, emit no capacity reports on toggles, and stop Mac-side resizes when the phone keyboard changes.
Host layout uses one constraint: renderWrapper.bottom = dock.top + steady chrome + slack, where slack = min(blankBelowContent, keyboard intrusion); alternate-screen apps disable slack. Host forwards window-level safe-area changes to trigger a grid resync, and strips in-flight animations on window detach.
SwiftUI hosting ignores the keyboard safe area at the bottom to keep the representable size invariant; the representable keeps
hostedAltScreenActivelive across mode flips.Content-bottom measurement reads the last non-whitespace rendered row on the serial output queue, runs immediately on keyboard raise, throttles (hidden ~1 Hz, visible ~4 Hz), and stays viewport-bounded.
Tests/infra: add TerminalKeyboardFullHeightPinTests; update spacing/UI tests for the dock seam and keyboard invariance; import QuartzCore for replay tests; restore the ghostty submodule pointer; drive chrome-hidden tests via internal
setChromeHidden.Migration: remove
TerminalLetterboxGeometry.drawableContainerSizeand all keyboard-height-based sizing. Keyboard toggles must not change font size or grid size (adopt main’s letterbox-at-base-font contract).Written for commit 3b1bfc1. Summary will update on new commits.
