29b15f19c1 Route terminal clipboard through tauri-plugin-clipboard-manager; bump to 0.2.3
navigator.clipboard.readText() triggers WebView2's "Allow clipboard access?"
permission prompt on every paste. The plugin goes through IPC + the OS
clipboard directly, so the prompt never fires.

Wired the Rust plugin, granted clipboard-manager:allow-{read,write}-text in
the capabilities manifest, swapped XtermPane's copy/paste handler to use
the plugin's readText/writeText.

cd9540b106 Add Ctrl+Shift+C / Ctrl+Shift+V copy-paste in terminal panes
Uses attachCustomKeyEventHandler so xterm doesn't first consume Ctrl+V
and inject a raw ^V into the PTY. Paste routes through term.paste() so
broadcasting and bracketed paste continue to work.

aab36afce4 Per-pane and global terminal zoom via keyboard
Each leaf now carries an optional fontSizeOffset, persisted in
workspace.json alongside everything else. Ctrl+= / Ctrl+- / Ctrl+0
adjust the active pane; adding Shift escalates to every pane (the
mirror of the broadcast Shift+Alt convention, with shift alone since
the keys are otherwise unused). Bindings match on e.code so layouts
that don't have "=" / "-" / "0" in the same spot still work.

XtermPane gained a fontSize prop. A secondary effect reacts to changes:
set term.options.fontSize, fit() to recompute cols/rows for the new
cell size, refresh(), then resizePane so bash redraws the prompt at
the right width. No remount, so PTY + scrollback survive zoom changes.

The new tree helpers (resolveFontSize / adjustFontSize /
adjustAllFontSizes) are metadata-only — they don't swap leaf ids, so
nothing respawns. reshapeToPreset also carries the offset across when
splicing existing leaves into a new layout. 12 new vitest cases pin
those invariants plus the clamp and reset-to-default behaviour.

Lead the "Using it" section with the keyboard shortcuts table, then
break the remaining behaviour into mouse/toolbar and broadcast/idle/
presets subsections. Documents drag-to-swap, the 180px resize minimum,
the home-cwd default, the new idle border + titlebar badge (replacing
the old toasts blurb), and the splice-preserving preset behaviour.

1720b60499 Bump version to 0.2.2
Changes since 0.2.1:
- Keyboard shortcuts: Ctrl+K palette + Ctrl+Shift+E/O/W for
  split-right / split-down / close, Ctrl+Shift+B per-pane and
  Ctrl+Shift+Alt+B global broadcast, Ctrl+Shift+Arrow for spatial
  pane navigation
- New panes default to WSL home (~) instead of inherited Windows cwd
- Resize artifacts: rAF-throttle gutter drag, debounce PTY resize,
  skip resizePane when cols/rows haven't actually changed (kills the
  idle-flap loop that surfaced with many panes)
- Minimum pane size (180px) enforced on both split and gutter drag
- 2px gap around each leaf so per-pane borders read as distinct
  rectangles instead of a continuous grid

45d0f4cd8b Add a 2px gap around each leaf slot so per-pane borders don't merge
With panes packed edge-to-edge, adjacent .leaf elements' 2px borders
touched directly. When all (or many) panes went idle, every pane's
red border combined with its neighbour's to form continuous red lines
across the whole window — looking like a single grid pattern, not
distinct per-pane outlines.

Fix: padding: 2px on .leaf-slot (box-sizing: border-box). Each .leaf
ends up inset 2px on every side, so adjacent panes have a 4px dark
gap between them and their borders read as separate rectangles.
Affects all borders equally (idle red, active blue, broadcasting
orange) and gives the layout a cleaner separation overall.

9827b01688 Skip PTY resize when cols/rows didn't actually change
Most ResizeObserver firings in XtermPane don't change xterm's cell
grid — just shuffle a few pixels around. We were still calling
resizePane() (which SIGWINCHs bash, which redraws its prompt, which
emits data, which resets the idle timer). With many panes, this
created a self-reinforcing flap loop where the idle indicator would
toggle every few seconds.

Now: track the last cols/rows we actually sent to the backend in the
mount effect's closure. If a debounced fit() ends up at the same
grid dimensions, skip the resizePane call entirely. No SIGWINCH, no
prompt redraw, no data event, no idle flap.

Zero functional change for actual resizes; only suppresses redundant
PTY syscalls.

daf0d4e88a Enforce minimum pane size (180px) on split and gutter drag
Spamming the ⇥/⇣ split buttons (or their Ctrl+Shift+E/O shortcuts)
used to subdivide panes indefinitely, leaving toolbar-only slivers
that were unusable.

- tree.ts: MIN_PANE_PX = 180 constant.
- App.tsx: the `split` orchestration callback now computes the active
  pane's pixel dimensions from its layout slot + the container rect,
  and refuses to split if either child would fall below MIN_PANE_PX.
  Surfaces the refusal via a `notify(...)` toast so the user knows
  why nothing happened.
- Gutter.tsx: pointermove clamps the new ratio so the smaller child
  stays at least MIN_PANE_PX wide/tall. Falls back to the old 0.05
  floor only if the parent is so small that two min-sized panes
  can't both fit (degraded but functional).

a5209e08ae Debounce PTY resize during drag to stop SIGWINCH-spam corrupting prompts
What the user saw: dragging a gutter filled the affected panes with
many overlapping bash prompts, some corrupted mid-print
(megaproxy@DESKTOP-megaproxy@DESKTOP-SSAQG5 etc).

Root cause: every resizePane() call sends SIGWINCH to the shell, which
makes bash redraw its prompt. The previous fix coalesced the local
xterm fit() into one per rAF, but still fired resizePane on every
rAF — 60+ SIGWINCHes per second during a drag, faster than bash can
finish one prompt redraw before the next interrupts it.

Fix: separate the two concerns. fit() + term.refresh() still run
every rAF (the visual must stay smooth). But resizePane() is
debounced to fire 150 ms after the LAST rAF — i.e. only when you
stop dragging — so bash gets one clean SIGWINCH at the final size
and produces a single tidy prompt redraw.

7d1f1f4b9a Default new panes to WSL home (~) instead of inherited Windows cwd
Previously: spawn_wsl(cwd=None) passed no --cd to wsl.exe, so each
pane inherited the launcher's cwd — which is typically
C:\Users\<user>, surfacing inside WSL as /mnt/c/Users/<user>. Annoying
because the first thing you do in a new pane is `cd ~`.

Now: if the caller didn't specify a cwd, we explicitly pass `--cd ~`
so the pane lands in the WSL user's home. Existing panes keep their
saved cwd from the workspace.json.

94bdb884ad Fix resize artifacts: rAF-throttle drag + force xterm repaint
Two related fixes for stale glyphs / visual artifacts while dragging
a gutter:

- Gutter.tsx: pointermove now writes the new ratio into a ref and
  schedules a single requestAnimationFrame flush per frame. Without
  this, setTree fires 60+ times per second during a drag and React
  + ResizeObserver + xterm's DOM renderer get out of sync. The
  pointerup handler flushes any pending ratio so the final position
  always lands.

- XtermPane.tsx: the ResizeObserver callback now also rAF-coalesces
  AND calls term.refresh(0, term.rows - 1) after fit.fit(). xterm's
  DOM renderer doesn't reliably repaint freed-up rows after a
  shrink, so the explicit refresh wipes any stale glyphs.

a4cd82440b Add keyboard shortcuts (Ctrl+Shift chord style)
| Ctrl+K           | palette                                |
| Ctrl+Shift+E     | split active pane right                |
| Ctrl+Shift+O     | split active pane down                 |
| Ctrl+Shift+W     | close active pane                      |
| Ctrl+Shift+B     | toggle broadcast on active             |
| Ctrl+Shift+Alt+B | toggle broadcast on ALL panes          |
| Ctrl+Shift+Arrow | focus neighbour pane in that direction |

The handler attaches at capture phase on window so it wins against
xterm.js. It bails when a non-terminal <input>/<textarea> is focused
so label edits and the palette input keep working normally.

Spatial neighbour-finding lives in tree.ts as findNeighborInDirection
— picks the leaf whose centre is most aligned in the perpendicular
axis, breaking ties by primary-axis distance.

Tooltips on toolbar/titlebar buttons now mention their shortcuts;
README has a key-binding table.

31bc4859cf Bump version to 0.2.1
Changes since 0.2.0:
- Fix broadcast no-op (useEffect deps captured stale orch ref, so paneIds
  got silently unregistered on every click → broadcastFrom found no peers)
- Flat-list layout architecture: render leaves as siblings keyed by id,
  position via absolute boxes. PTYs survive any tree reshape.
- Drag a pane's toolbar onto another pane to swap them
- Idle reporting moved out of toast spam into a "N idle" titlebar badge
  + red pane border + red "idle" status text
- Themed terminal scrollbars
- Global 📡 broadcast toggle in the titlebar
- Presets preserve existing panes' shells (only kill what overflows the
  preset's slot count, with a confirm dialog)
- React 18 frontend (Svelte version retired to svelte-archive branch)

d9ddf52699 Replace idle toasts with pane border + titlebar badge
Old behaviour: every pane fired orch.notify("X is idle") after 5s of
silence, stacking up to N toasts that took ages to dismiss.

New behaviour:
- LeafPane tracks its own isIdle state locally and reports up via
  orch.reportLeafIdle(leafId, idle).
- App aggregates into a Set<NodeId> and renders "N idle" in red after
  the "N panes" count in the titlebar (hidden when zero).
- The pane itself gets a red border (.leaf.idle) — but active and
  broadcasting borders still take precedence, so the focus indicator
  isn't masked by idle status.
- The pane's "alive" status text in the toolbar swaps to red "idle"
  while it's quiet (reverts to "alive" the moment output arrives).
- Idle clears immediately on the next byte of output (no 1-second lag)
  AND when the pane unmounts (cleanup effect).

No more flood of toasts.

c93ebddfa5 Drag a pane's toolbar onto another pane to swap them
New interaction: click-and-drag any pane's toolbar onto another pane
to swap their positions in the tree. The shells / scrollback stay
intact (each leaf keeps its data; only the tree slot it occupies
changes).

Implementation:
- tree.ts: `swapLeaves(root, idA, idB)` walks the tree once,
  substituting one leaf for the other at each occurrence. The leaf
  objects themselves carry their id/distro/cwd/label/broadcast across,
  so React preserves the LeafPane instances via the flat-list keying.

- orchestration.tsx: add drag lifecycle to the context —
  dragSourceId / dragOverId (reactive) plus beginHeaderDrag,
  setHeaderDragOver, endHeaderDrag (stable methods).

- App.tsx: implement those methods. endHeaderDrag(true) swaps if
  source and over are different leaves.

- LeafPane.tsx: pointerdown on .pane-toolbar (skipped if the target
  is a button/input). 5px movement threshold before drag commits to
  prevent accidental swaps when clicking a chip etc. Pointer-capture
  the toolbar so we keep getting move events even outside it. Use
  document.elementFromPoint to find the leaf under the cursor.

- CSS: source pane fades to 40% opacity during drag; target pane
  shows a 3px dashed blue outline; toolbar shows grab/grabbing
  cursors.

c4747546e0 Flat-list layout: render leaves as siblings keyed by id
The fix for the real preset bug: previously, presetSingle/2H/3H/2V/2×2
appeared to preserve panes (we copied id/distro/cwd/label/broadcast
into the preset's slots), but React's reconciliation tore down every
LeafPane and re-mounted it because the tree structure changed —
killing all PTYs and spawning fresh shells. The "preservation" was
data-only; the React components didn't survive.

Solution: stop rendering the Pane → SplitNode → LeafPane recursion.
Walk the tree to produce a FLAT layout of `{leaf, box}` entries (each
box is top/left/width/height as fractions 0–1). Render all leaves as
siblings of a relative-positioned container, each absolutely
positioned by its box. Key each one by leaf.id — React preserves the
component (and its XtermPane → PTY) across any tree reshape; only the
inline style changes.

Gutters render as separate sibling overlays at the split boundaries,
each with its own pointer handlers. Dragging mutates the split's
ratio via `updateSplitRatio(tree, splitId, r)`; the layout
recomputes; leaf boxes change; nothing remounts.

Now: clicking 2×2 on 4 stacked panes keeps all 4 shells alive and
just rearranges them into the grid. Same for any preset that doesn't
overflow.

Side benefit: removed the recursive Pane.tsx + SplitNode.tsx + their
CSS. The render path is now straightforward, no recursion, easier to
reason about.

8c3af8f9ee Preserve existing panes when applying a preset
Previously: clicking 1 / 2H / 3H / 2V / 2×2 in the titlebar replaced
the whole tree with brand-new empty leaves, killing every shell — and
the only safeguard was a window.confirm() that's easy to miss-click.
The user lost work whenever they reached for a preset.

New behaviour via `reshapeToPreset`:
- The preset's shape is built fresh (1, 2, 3, or 4 slots), then existing
  leaves are spliced into those slots in DFS order. Their id / distro /
  cwd / label / broadcast all carry over, so the same PaneId is still
  mapped — the PTY keeps running.
- If the preset has MORE slots than existing leaves (e.g. 1 pane → 2×2),
  the extra slots stay as fresh empty leaves and new shells spawn there.
  No prompt — pure additive change.
- If the preset has FEWER slots than existing leaves (e.g. 8 panes →
  2×2), the overflow leaves are returned in `dropped`. We confirm with
  the user, and if they accept, kill those PTYs explicitly.

Tradeoff: split ratios reset to 0.5 (the whole point of "apply preset"
is to use its layout). That's an acceptable cost.

2a0c096095 Fix broadcast no-op: stop depending on orch object in LeafPane effects
The bug: clicking 📡 made the visual update (orange border) but typing
in a broadcasting pane only wrote to that pane — peers never received
the keystrokes.

Root cause: the orch context value (useMemo'd over activeLeafId,
distros, and the operation callbacks) is recreated every time
activeLeafId changes (i.e. every click). useEffect cleanups in
LeafPane that had `orch` in their deps fired their cleanup-then-setup
cycle on every click. The unmount-cleanup for paneId registration
ran `orch.registerPaneId(leaf.id, null)`, silently deleting paneIds
from App's paneIdByLeafRef map — so when broadcastFrom later walked
the tree looking up peers, the map returned undefined for every leaf
and the actual writeToPane calls never happened.

Fix: depend on the specific stable method references
(`orch.registerPaneId`, `orch.notify`, etc.) instead of the orch
object itself. The methods are all useCallback'd with stable deps
in App.tsx, so their references don't change across orch object
recreations — effect deps stay stable, no spurious cleanup.

Applied the same fix to all orch-using effects/callbacks in
LeafPane (commitLabel, pickDistro, onPaneClick, onPaneSpawned,
onXtermFocus, onTerminalInput, idle interval, paneId cleanup).

369ec8e2fd Theme scrollbars + global broadcast toggle
Two small QoL additions:

- styles.css: WebKit pseudo-element styling for .xterm-viewport
  scrollbars (8px wide, dark thumb #2a2a2a on transparent track,
  hover lighten). Matches the rest of the dark theme so the right
  edge of each terminal stops looking like default OS chrome.

- tree.ts: setAllBroadcast(root, on) helper that flips every leaf's
  broadcast flag to the given value, preserving object identity
  where nothing changed.

- App.tsx: titlebar 📡 button showing global broadcast state
  ("all off" / "all on" / "N/M"). Click toggles every pane between
  all-broadcasting and all-off. Orange when any panes are
  broadcasting; darker orange when partial.

774b8633dc Migrate frontend from Svelte 5 to React 18
After hours of fighting Svelte 5's prop-reactivity through the
recursive Pane → SplitNode → LeafPane chain (props captured at
mount, never updated; context+getter pattern crashed; DOM-direct
workarounds created zombie-split click-intercept bugs), we
checkpointed the Svelte version (branch svelte-archive at e9015b2,
tarball at D:\archives\tiletopia-svelte-2026-05-22.tar.gz) and
rewrote the frontend in React.

Kept verbatim:
- All of src-tauri/ (Rust backend, Tauri config, icons)
- scripts/ (make-icon.py, release.sh)
- README.md, CLAUDE.md, memory.md
- src/lib/layout/tree.ts (pure TS — 43 tests still pass)
- src/ipc.ts (Tauri command wrappers)

Rewrote in React:
- src/App.tsx (top-level state via useState, OrchestrationProvider
  for descendants via React.Context)
- src/lib/layout/orchestration.tsx (React Context API for shared
  state — known-reliable reactivity, no Svelte 5 wall)
- src/lib/layout/Pane.tsx (recursive dispatcher)
- src/lib/layout/SplitNode.tsx (draggable gutter, local ratio state)
- src/lib/layout/LeafPane.tsx (toolbar + XtermPane)
- src/components/XtermPane.tsx (xterm.js wrapper, refs for callbacks)
- src/components/Notifications.tsx, Palette.tsx

Build: Vite + @vitejs/plugin-react. TypeScript strict. Same Tauri 2
config. Verified: pnpm check (clean), pnpm test (43/43 pass).
Not yet verified: pnpm tauri dev — that requires the Windows host.

e9015b2790 Restore workarounds; close via renderKey bump (kills all PTYs)
Agents investigated the close-button-stuck issue and recommended
removing all DOM-direct workarounds, hypothesising they were causing
the bug. Tested empirically: removing the workarounds breaks
EVERY interactive feature (no border, no broadcast, no resize,
no close). So Svelte 5 prop reactivity through the recursive Pane
chain is genuinely broken in this app — workarounds are required.

Restored workaround set:
- App.svelte polling loop: focus detection + active-class + broadcast
  class sync via DOM API every 250ms
- SplitNode.svelte drag: rAF-throttled direct .side flex update
- handleClose: bump renderKey to force full Pane remount. This kills
  every other pane's PTY (cost) but is the only reliable way to make
  the closed pane actually disappear AND avoid the "zombie split"
  click-intercept bug from the previous DOM-hide approach.

The underlying Svelte 5 issue remains an open question — the next
thing to try is the context+getter pattern (`setContext('active',
{ get id() { return activeLeafId } })` in App, `getContext('active')`
in LeafPane) which Agent 1's research found is the documented
escape hatch for deep reactive prop chains.

40ce27251d Close: bubble-up DOM hide + key-bump on full collapse
Two improvements to the close-pane workaround:

1. When both children of a parent split are now hidden, the .side hide
   bubbles up to the parent split's own .side and hides that too. Needed
   for deeply-nested splits where closing leaves at the bottom should
   propagate the visual collapse upward.

2. When closeLeaf returns null (the user closed the last remaining
   leaf), force a full Pane remount via {#key renderKey} bump. The
   DOM-hide approach can't simulate mounting a fresh tree node, so this
   is the one place where we take the cost of a full unmount + remount.
   Only fires when the entire tree resets — not on intermediate closes.

8d5c49155b Restore DOM-direct workarounds; throttle gutter drag
After this session's diagnostic confirmed the root cause (Svelte 5
prop reactivity does NOT propagate through Pane → SplitNode → LeafPane
in this app — each LeafPane captures props at mount and never sees
updates), restored the brute-force DOM workarounds that were proven
to work and threw in a throttle for the gutter drag.

What changed vs the broken intermediate state:
- App polling: re-sync .leaf.active, .leaf.broadcasting, .bcast-chip.on
  classes from tree+activeLeafId state every 250ms. Bypasses Svelte
  reactivity entirely.
- SplitNode drag: rAF-throttle the direct flex update so we stop
  spamming SIGWINCH to the PTYs (which was making shells redraw
  prompts repeatedly, creating the visual artifacts the user reported).
- Close: keep the targeted PTY-kill + DOM-hide-the-side approach so
  panes visually disappear and siblings fill via flex auto-allocation.

This isn't pretty, but it works. The proper fix is to either find /
file the Svelte 5 bug, or migrate the frontend to a framework whose
reactivity we can trust. Both deferred.

058ce49d3b Force gutter-drag resize via direct DOM (same workaround)
Dragging the splitter set node.ratio in the Svelte $state tree
correctly (used by save-restore), but the template binding
style=\"flex: {node.ratio}\" on each .side div didn't re-evaluate
when ratio changed — same prop-reactivity wall we hit with the
active border and broadcast color. The gutter would drag invisibly:
internal state moved, panes stayed at their original ratio.

Workaround: SplitNode's onPointerMove now ALSO writes the flex
style directly to the two .side elements via DOM. Svelte still owns
node.ratio for persistence/serialization, but the visual is owned
by the imperative DOM write.
