The terminal fix was only one instance. An audit of the other pane toggles
found ⌘G and ⌘J diverging the same way, proven with a probe: with review
stacked behind files in the right column, or either pane inside a minimized
zone, the store reads open while nothing is on screen, so the press
re-asserts a value it already held and the key does nothing.
isPaneVisible / togglePaneVisible replace the tool-panel-only pair and now
back every toggle. Close still routes through closeTreePane, so each pane
keeps its own semantics: a tool panel collapses to its rail, files and
review close through their store, anything else is dismissed.
files and review were bound with a closer and no opener, so the boolean went
stale as soon as anything but the toggle revealed them. bindPaneVisibility
moves into the tree store beside bindToolPaneCollapse, documents the two as a
pair, and both panes now pass both halves. Keeping the binding in the store
also means the tests drive the real function — the earlier copy in the test
file passed with the fix reverted, which is how the missing opener survived
the first pass.
setTreePaneHidden keeps its quiet path: a reactive unhide (a cwd arriving)
must not front or un-minimize over what the user is looking at. Only user
intent goes through the reveal path.
The terminal and logs carried a 7.5rem minHeight, so dragging the seam down
jammed against a floor with a sliver of unusable terminal still showing.
Tool-panel zones now floor at COLLAPSED_ZONE_PX (the h-7 header strip)
instead of the generic 80px, and releasing at that floor minimizes the zone
rather than persisting the sliver — it folds to its collapsed header,
vertical rail or horizontal strip depending on the parent axis. The sliver
size is never written, so restoring returns the height it had before.
Two independent clobbers threw the choice away, so "hide header" never
survived a close/reopen cycle.
normalize() deleted headerHidden whenever a zone dropped to one pane, on
the grounds that a lone zone is headerless by default. It is — but the flag
is the user's standing preference for that zone, not a redundant value, and
dropping it meant the bar returned the moment a pane rejoined (close the
stacked logs pane, toggle it back).
Re-adoption then pinned headerHidden false unconditionally. That is right
for a pane arriving somewhere new, where zero chrome leaves no handle to
drag or close, and wrong for a zone whose bar the user deliberately hid.
Adoption now carries the destination zone's own setting, read before the
insert since insertAtGroup pins the flag itself on a center drop.
Dragging the terminal to the bottom stacks logs into its zone, and every
tool-panel toggle broke in that stack.
Boot revealed instead of leaving the tree alone: bindPaneCollapse ran
setPaneCollapsed(id, !open), and `false` there fronts the pane. Logs binds
last, so it stole the active tab from the persisted tree. Ctrl-` then asked
to collapse a terminal that was no longer the active tab, the shared-zone
branch declined by design, and the key did nothing until the stack was
broken up. Boot now only ever collapses.
The toggles also asked the wrong question. !$terminalTakeover.get() flips a
boolean that has no idea what is on screen, so once anything else moved the
pane the press spent itself re-asserting a value the store already held.
toggleToolPane derives from the tree instead, and ctrl-`, Cmd+J's terminal
fallback, the statusbar button and the logs palette row all route through
it. The terminal cycle/close keys drop the same stale boolean.
bindPaneCollapse moves into the tree store as bindToolPaneCollapse so the
boot rule is testable against the real function rather than a copy.
Two things made a tool panel tab feel unclosable.
Cmd-W was a dead key over the terminal and the logs pane. The keyboard
close ladder resolved its target with focusedSessionGroup, which only
matches zones hosting a CHAT strip, so a focused tool panel fell through
every rung and Cmd-W emptied the main tab instead. Add a tool rung that
resolves through the same hover/focus ladder the number keys use.
Right-click Close was missing or inert. The zone menu's target was only
resolved by the tab strip's own onContextMenu, so a right-click anywhere
else in the zone (pane body, collapsed rail, edit veil) reused the
PREVIOUS target -- landing on the uncloseable workspace dropped Close
from the menu entirely. Resolve the target on the zone instead, so every
surface that opens the menu names the chip under the pointer.
Close on a tool panel now takes the tab out of the strip and syncs its
owning store, so the ctrl-backtick toggle and the Cmd-K row stay
truthful and bring the pane back; the toggle's open path reveals
(un-dismiss + re-adopt) rather than un-collapsing a pane that has left
the tree.
The logs (and terminal) tab ✕ dismissed the pane from the layout but
never synced the owning store — so the ⌘K toggle was stale and its open
listener called setPaneCollapsed, a no-op when the pane isn't in the
tree. The tab was gone with no way back short of a layout reset.
Route the tab ✕ through closeCollapsePane (dismiss + store sync) so the
toggle stays truthful, and make bindPaneCollapse's open listener call
revealTreePane (un-dismiss + re-adopt) instead of setPaneCollapsed.

The statusbar is now opt-in. Existing users with a stored preference
keep their choice; new users get a clean bottom edge. The way back is
the view.toggleStatusbar keybind or the ⌘K row, unchanged.
powerMonitor's AC/battery state is mirrored to the renderers
(store/power.ts) and visiblePoll quadruples its cadence on battery. Only
the safety-net refreshes slow down — event-driven refreshes and live
streaming are untouched.
It loads arbitrary user-linked pages offscreen; unthrottled, a heavy page
burns full CPU for the window's whole lifetime. Title resolution rides
load events and main-process timers, which throttling doesn't touch.
The process-wide disable-background-timer-throttling /
disable-backgrounding-occluded-windows switches plus a static
backgroundThrottling: false on every chat window pinned each renderer's
document.visibilityState to 'visible' for the life of the window. Every
visibility-gated backstop poll and clock tick in the renderer became an
always-on timer: an idle, minimized Hermes burned ~20% CPU around the
clock, on battery too.
Throttling is now a runtime dial. A small controller (stream-throttle.ts)
rides the merged hermes:active-work reports the quit guard already
receives: while any turn is in flight every chat window gets
setBackgroundThrottling(false) — a live answer keeps painting while
blurred, occluded, or minimized, exactly as before — and once all turns
settle (plus a 5s trailing window so the final flush lands at full
cadence) Chromium's default throttling returns and hidden windows go
quiet.
disable-renderer-backgrounding stays: process priority only, no timer
semantics, and it keeps hidden streaming fast.
Select-all + Cut emptied the text and left the composer blank — no draft,
no prompt. Delete had the same hole.
The placeholder is painted on `:empty`, and a cleared editor keeps a
scaffolding <br> so the contenteditable can't collapse to a sliver. Those
two facts collide: the moment the break lands the editor has a child,
`:empty` goes false, and the prompt never comes back.
CSS can't infer emptiness on its own either. A text node is invisible to
selectors, so `one<br>` and a lone `<br>` are the same shape — a structural
rule like `:has(> br:only-child)` paints the placeholder straight over the
user's text. The code that empties the editor is what knows, so it marks
the root and the condition reads `:is(:empty, [data-empty])`.
Both writers that reshape that root maintain the marker through one helper:
the normalizer, and renderComposerContents for a restored draft or an undo.
The message-edit composer shares the slot and the rule, so it takes the
same shared class instead of drifting on its own copy.
#74815 fixed the draft this stashed; the placeholder is a separate seam.
The tab strip decided the close gesture from the `uncloseable` flag, which the
workspace sets to keep its pane in the tree — so the one tab whose close now
does something couldn't be ⌘-clicked or middle-clicked, and its right-click
menu had no Close.
Read the gesture off the pane's registered closer instead, with the workspace
registering closeWorkspaceTab. An atom rather than a lookup, since that closer
comes from a wiring effect that lands after the strip's first paint.
The workspace pane can't leave the tree, so "close the main tab" only ever had
one answer wired: shift the next stacked session in. With main as the only tab
there was nothing to shift and ⌘W dead-ended on the tab the user was looking
at.
closeWorkspaceTab is now the one answer for every entry point — stacked
session still wins, and with nothing stacked main drops to a fresh New session
draft. A blank draft and a full-page view stay no-ops: a blank draft already
IS the post-close state.
Chromium on Windows and Linux answers a middle press inside a scroller by
starting the autoscroll pan, and the mouseup that ends the pan never becomes
an auxclick. Every surface carrying the gesture — tab strips, the session
list, the terminal rail — is a scroller, so middle-click only ever worked on
macOS, where autoscroll doesn't exist.
Arm on pointerdown, spend on the pointerup over the same element (press one
tab, release on another and nothing happens), and cancel the middle mousedown
on every press so the pan widget can't appear on a surface that owns the
button. One helper, four call sites.
⌥-drag is the app's force-selection gesture over mouse-mode TUIs, but
xterm's default alt-click-moves-cursor claims the same click and emits one
cursor left/right escape per column of travel. Shells that don't consume
them echo the raw `^[[D` burst into the buffer. One gesture, one meaning.
Both of xterm's link paths activate through `window.open()`, which the
window's setWindowOpenHandler denies, so ⌘-clicking a URL did nothing but
log "Opening link blocked as opener could not be cleared" — and the OSC 8
path fronted that dead end with a raw confirm() dialog. Route both through
the desktop bridge, the path every other external link in the app takes.
⌘-click on macOS, Ctrl-click elsewhere, matching VS Code's integrated
terminal, Terminal.app, and iTerm2. A bare click stays with the selection so
a misclick on a URL can't launch a browser.
ChatView migrated tip-keyed composer queue/draft entries onto queueSessionKey
whenever the two ids differed. queueSessionKey is route-driven and can flip to
Session B a frame before the store selection leaves Session A, so migrate
re-homed A queue entries onto B and the idle ChatBar auto-drained them into
the wrong chat.
Gate migrate on same-conversation lineage only (tip to root). Also honor
lineage when background queue drain decides selected/busy, so a root queue key
is not treated as idle/offscreen while the compression tip is still working.
The row fell back to the global $repoStatus whenever repoPath was blank,
painting the main pane's branch and ± onto a tile whose cwd hadn't
resolved yet. The fallback bought nothing — the primary computed is keyed
to $currentCwd, which is empty in exactly that case — and cost a rail
showing a tree the session was never in.
A tile and a branched session each live in their own worktree and render
from their own SessionView slice, so neither is the main pane's session.
Pass foreground: false at both call sites.
applyRuntimeInfo unconditionally mirrored a runtime's cwd, branch, model
and usage into the global composer atoms. Every tile create and session
branch called it, so opening a session in another worktree re-pointed the
MAIN pane's coding rail at that tile's repo — and persisted it, so the
wrong workspace cwd survived a restart.
Collect the patch first, then mirror it once behind a `foreground` gate.
Background callers still get the full patch for their own session state;
they just stop publishing into state they don't own.
