Resizable splitters: draggable gutters between grid tracks adjust per-layout
column/row fractions (fr units), applied as an inline grid-template and persisted
(web-terminal:grid-splits). The fraction math (adjustSplit — trades delta between
adjacent tracks, clamps to a minimum, conserves the total) is a pure, unit-tested
helper in grid-layout.ts; the drag translates pixel motion into an fr delta.
Saved presets: public/grid-presets.ts — a toolbar dropdown to save the current
layout + its split under a name, re-apply it in one click, or delete it
(web-terminal:grid-presets). Desktop-only, like the layout toggle.
- grid-layout.ts: layoutTracks, defaultSplit, adjustSplit, tracksToTemplate,
load/saveGridSplits, splitForLayout (validates stored shape).
- tabs.ts: renderGutters/beginGutterDrag/setSplit; applyLayout sets the inline
template; gridArrangement()/applyGridPreset() hooks.
- main.ts: mount the presets dropdown. style.css: gutters + presets menu.
- tests: splitter math + persistence + a stubbed drag repro (1.2fr/0.8fr); presets
persistence + dropdown (save/apply/delete/close). typecheck+build clean, 1612 pass.

A quadrant can be flipped to "monitor" mode via a 👁 header toggle: instead of
the live interactive terminal, it renders the session's screen from periodic
GET /live-sessions/:id/preview snapshots into a read-only xterm. A monitored
quadrant never attaches a WS and never sends a resize, so — unlike a live
quadrant (latest-writer-wins) — it does not drive the shared PTY size. That lets
you watch a session in a small quadrant without shrinking it for another device
using it full-screen (the cross-device shrink the split-grid design flagged).
- public/cell-monitor.ts (new): mountCellMonitor(host, id) — polling read-only
preview, scaled to fit, best-effort, disposes cleanly (no write after dispose).
- tabs.ts: per-entry monitor state; applyLayout keeps the live pane hidden and
starts/stops the monitor; 👁 toggle in the cell header; teardown on close /
leaving grid mode.
- style.css: monitor button + .cell-monitor container.
- tests: cell-monitor.test.ts (poll→write, dispose, late-resolve guard) + monitor
wiring in tabs.test.ts. typecheck + build clean, 1587 tests pass.

Builds on the v1 watch board:
- Two more layouts: row-3 (1×3) and grid-6 (2×3). A single `grid` marker class on
#term now carries the shared cell chrome so it no longer enumerates each lay-*.
- Ctrl+` cycles the focused quadrant (Ctrl+Shift+` reverses); matchFocusCycleKey
is an exported pure helper so it's unit-tested. No-op / passthrough in single mode.
- Per-quadrant ⛶ maximize: the focused cell expands to fill the grid as an absolute
overlay while siblings stay live behind it; follows focus, resets on layout
change / tab close.
- Drag a tab from the tab bar onto a quadrant to assign it there (reuses the
existing tab-drag dragIndex); grid-only.
Adversarial review (3 lenses → per-finding verify, incl. a headless-Chrome repro)
caught a HIGH: maximizing via `grid-column/row: 1/-1` shoved siblings into implicit
rows — a strip instead of fullscreen AND a spurious resize to backgrounded live
PTYs. Fixed with an absolute-overlay (`position:absolute; inset:0`), then verified
in real Chromium (Playwright): maximized cell fills #term, siblings 0px size delta.
Also: silence a covered pane's pending pulse under maximize; coarse-pointer target
for .cell-max. Verified: typecheck + build:web clean, 1579 tests pass.

When several sessions are open on a large screen (≥1024px), the terminal
area can split into 1×2 or 2×2 so multiple LIVE, interactive terminals show
at once — a monitoring convenience for vibe-coding several Claude sessions.
Design keeps activeIndex as the single focused pane, so keybar/voice/approval
routing is unchanged; a new gridLayout + derived visible-set lets several
.term-cell wrappers show together inside a CSS-grid #term. The server and WS
protocol are untouched.
- public/grid-layout.ts (new): layout types/capacity, visibleIndices,
matchMedia desktop gate (GRID_MIN_WIDTH=1024), persistence, toolbar toggle.
- tabs.ts: pane→.term-cell wrapper (header + terminal + inline-approve footer);
applyLayout() owns show/hide + grid class + cell order + placeholders;
board-aware activate() (never focuses a hidden pane); setFocused/setGridLayout
delegate to it; renderCell/renderInlineApprove; refitVisible; notification
suppression for on-screen panes (factoring in the home overlay).
- terminal-session.ts: show({focus}) so non-focused quadrants don't steal
keyboard focus; onFocus callback (capture-phase pointerdown).
- main.ts: mount the toggle; window-focus refit → refitVisible.
- style.css: cell/grid model (.term-pane → relative flex child), focus ring,
pending pulse, inline approve, placeholder, toggle + coarse-pointer targets.
- tests: grid-layout.test.ts + split-grid block in tabs.test.ts (+33).
Adversarial review (4 lenses → per-finding verify) caught and fixed a HIGH:
activate() was not board-aware, so opening a tab on a full grid focused a
hidden pane (typing into an invisible session). Verified: typecheck + build:web
clean, 1566 tests pass, grid-layout 95% / tabs 94% coverage.

viewport-fit=cover spans the physical screen edges; add --safe-t/--safe-b from
env(safe-area-inset-*) threaded through #tabbar/#term/#keybar/#approvalbar/#searchbox/
#settingspanel. Falls back to 0px (zero regression on non-safe-area platforms).
The flat Projects grid was overwhelming at 50-100 repos. Explored the UX with
4 parallel agents (auto-grouping / manual folders / density-segmentation /
competitive research); all converged on namespace auto-grouping as the primary
fix — the dotted repo names (Billo.Platform.*, Billo.Infrastructure.*) already
encode the hierarchy, so it's a string-split, not a taxonomy the user builds.
Frontend:
- groupProjects(): depth-2 namespace grouping, >=2-member threshold (singletons
fall to "Other"), degrade-to-flat when repos share no prefix, running projects
duplicated into a pinned "Active now" section.
- displayLabel(): cards show the namespace tail (Payment, not
Billo.Platform.Payment); full name in Active/Other.
- Collapsible sticky group headers with an "N active" badge so a collapsed
section never hides running work; search force-expands matching groups.
- public/prefs.ts: server-first load with a localStorage offline mirror, migrates
the legacy per-device proj-favs.
Backend (server-side prefs so favourites + collapse-state follow the user across
devices — localStorage was per-device, which broke the multi-device premise):
- src/http/prefs-store.ts: ~/.web-terminal-prefs.json store (mirrors push-store),
every field bounded + sanitized.
- GET /prefs (read-only) + PUT /prefs (Origin-guarded); UiPrefs type +
PREFS_STORE_PATH config.
Tests: +12 prefs-store, +21 groupProjects/displayLabel. Full suite 1227 passed.
Verified live: grouping renders, collapse persists to the server and survives a
full page reload (cross-device sync proven end-to-end).
Give the two tab-bar line-icon buttons the same styled data-tip hover tooltip as
the toolbar icons, so their meaning is clear on hover (native title was slow/ugly):
- timeline → "Activity timeline"
- push toggle → "Notifications off — tap to turn on" / "…on — tap to turn off"
Left-anchored (they sit on the left of the tab bar). 158 push+tabs tests green.
The icons were swapped to lucide line icons, but the buttons kept a boxed/light
background that clashed with the minimal toolbar icons. CSS-only fix: render
.tab-timeline + .push-toggle-btn as transparent, monochrome 18px line-icon
buttons (text-dim, accent on hover/active) — identical to .toolbtn — overriding
the earlier boxed default. Markup unchanged (tests stay green: 158 push+tabs).
The detail page now reads <repo>/CLAUDE.md and shows it in a scrollable
monospace box, with one smart button: "↻ Update" when it exists / "✨ Generate"
when it doesn't. The button opens an interactive Claude session in the repo
running /init (claude "/init") so you review what it writes — reuses the project
launcher, no new backend orchestration, stays a byte-shuttle.
- ProjectDetail += hasClaudeMd / claudeMd; buildProjectDetail reads CLAUDE.md
(truncated 64KB, best-effort, in the existing Promise.all)
- renderProjectDetail: CLAUDE.md section (content box or empty state) + button
- style.css: .proj-section-row / .proj-claudemd-btn / .proj-claudemd
Tests +5 (458): backend read present/absent; frontend content+Update,
empty+Generate, button opens `claude "/init"`. Verified: tsc clean, full suite
green, build OK, curl returns the content, in-browser shows the box + button.
The glossy emoji (🔍⚙▦🕘⌨🔗📱) clashed with the Amber dark theme. Swap them
for clean lucide line icons (MIT, stroke=currentColor) so they take the theme
colour — muted by default, Amber on hover — and add a styled CSS hover tooltip
(data-tip, right-anchored so it never clips the edge) showing what each does.
- public/icons.ts: 7 line icons (search/settings/dashboard/history/keyboard/
share/device), script-generated from lucide
- 7 toolbar modules: innerHTML = ICON_* + data-tip + aria-label
- style.css .toolbtn: 18px svg, --text-dim → --accent on hover, [data-tip] tooltip
Frontend-only. web typecheck + build clean; bundle has 0 toolbar emoji; verified
in-browser: line icons in theme colour, amber + tooltip on hover.
The big solid-amber "+ New session" button clashed with the refined segmented
control. Replace it with a dashed "+" tile that leads the session grid (same
size as the session cards, re-prepended each refresh), so it reads as a natural
"create" cell. Header is now just the title + Sessions/Projects toggle; the
redundant empty-state message is gone (the tile is the CTA).
Frontend-only (launcher.ts + style.css). Verified: web typecheck + build clean,
preview-grid tests green, in-browser the grid leads with the New-session tile
followed by the session cards (Open/Kill).
The detail view could kill sessions, but the grid card's session rows were
enter-only. Add a ✕ kill button to each card session row (stopPropagation so it
doesn't also enter the session); makeSessionRow gains an optional onKill,
makeProjectCard an optional onKillSession, and mountProjects wires it to
DELETE /live-sessions/:id followed by a refresh.
Frontend-only. projects-panel tests +1 (51): ✕ present only with the callback,
click kills the right id without entering. Verified in-browser: a card with 2
sessions dropped to 1 after clicking ✕.
Clicking a project's name opens an in-app detail view (back button returns to
the grid) with:
- header: name, path, branch, dirty
- Branch / Worktrees: each `git worktree list` entry (branch or detached@head,
main/current/locked/prunable tags, path) — a single-worktree repo shows its
branch; a multi-worktree repo shows them all
- Active sessions (N): detailed rows (status, devices watching, started-ago)
with Open + Kill
- the Claude/Codex/VS Code launcher row
Backend: src/http/worktrees.ts (parseWorktrees pure + listWorktrees via
execFile, no shell, best-effort); buildProjectDetail(cfg, path, liveSessions)
in projects.ts (validates absolute existing dir, reuses branch/dirty/session
helpers, uncached — detail is on-demand and wants fresh state); read-only
GET /projects/detail?path= (no Origin guard, like /projects; 400 missing /
404 invalid). Types: WorktreeInfo, ProjectDetail.
Frontend: detail view + navigation in projects.ts (grid<->detail), project
name becomes a link, Kill via DELETE /live-sessions/:id.
Tests +21 (452 total): worktree parser, buildProjectDetail (validation,
non-git, session merge, real git-init worktree), renderProjectDetail.
worktrees.ts 100% / projects.ts 93.8% cov. Verified in-browser: opened a
Claude session, then the detail showed its branch+worktree and the live
session with Open/Kill.
Replace each card's "+ start claude here" with a row of three brand-logo
launcher buttons (logo + caption, touch-friendly, tooltips):
- Claude (coral burst) → new terminal tab running `claude`
- Codex (OpenAI mark) → new terminal tab running `codex`
- VS Code (blue ribbon) → opens the repo in VS Code ON THE HOST
VS Code: new guarded POST /open-in-editor runs `<EDITOR_CMD> <path>` (default
`code`) on the host via execFile (no shell); path validated as an existing
absolute dir; Origin guard (CSRF) like the DELETE routes. EDITOR_CMD config added.
Active-session highlight (user request): when a project has a running Claude
session (Claude-hook status != unknown — plain shells/codex stay unknown), the
Claude logo gets a coral ring + tint, with a count badge when more than one.
New: public/icons.ts (simple-icons SVGs, fill=currentColor), src/http/editor.ts.
onOpenProject gains an optional cmd; makeProjectCard exported for tests.
Tests +16 (431 total): editor validation/launch, EDITOR_CMD config, launcher
row (3 buttons, claude/codex commands), and the active-Claude highlight + badge.
Verified: coverage >=80x4, build OK, both typechecks clean; in-browser the 3
logos render with brand colours, and POST /open-in-editor actually launched
VS Code on the host (403 no-Origin / 400 bad-path / 204 valid-dir all correct).
The toggle sat on its own dedicated row, leaving a large empty band above the
project grid. On desktop (>=769px) float it top-right on the SAME row as the
filter box / launcher header: panels fill from the top (inset 0), launcher-head
reserves right padding for the pill. Mobile keeps the centred stacked toggle to
avoid overlapping the full-width filter on narrow screens. Also reclaim the
hidden key-bar's space on the home view (body.home-open #term { bottom: 0 }).
CSS-only (style.css is served directly). Verified in-browser: toggle and filter
share a row on Projects, no overlap with New/Manage on Sessions.
- Segmented control: replace the two free-standing bordered boxes with a
single rounded track holding two pill buttons (iOS-style), active segment
filled Amber; centred via fit-content + margin auto. Panel top-offset 44→68px.
- Hide the bottom key-bar on the home chooser (it only targets an active
terminal): updateHomeView toggles body.home-open; CSS hides #keybar.
Frontend-only. 415 tests green; both typechecks clean; verified in-browser
(toggle pill renders, keybar hidden on home, reappears when a tab opens).
Once a project/session tab was open, the home chooser (Sessions/Projects
segmented control) was hidden and only reachable by closing every tab — no
way back to the Projects view to open another project.
Add a ⌂ Home button to the tab bar that overlays the chooser on top of the
open tabs (homeForced flag; updateHomeView shows home when no tab OR forced,
hiding the terminal panes). Clicking ⌂ again, clicking a tab (activate resets
homeForced), or opening another session/project dismisses the overlay.
Closing the last tab resets the flag. The button highlights while active.
Tests: +3 (tabs.test.ts). Full suite 415 green; both typechecks clean;
verified in-browser (open tab → ⌂ → Projects panel reachable → ⌂ → terminal).
Prior-session prep for the v0.6 Project Manager, checkpointed on the
v0.6-projects branch as a clean base for the parallel builders:
- P1 (src/types.ts): ProjectInfo + ProjectSessionRef contracts; Config
gains projectRoots/projectScanDepth/projectScanTtlMs/projectDirtyCheck.
- P3 (src/config.ts): parseBool + parseProjectRoots helpers; parse the
4 PROJECT_* env vars with defaults ([homeDir]/4/10000/true).
- UI: public/style.css indigo -> Amber (#e3a64a) accent theme.
- Docs: FEATURE_PROJECT_MANAGER.md (1:N session design), THEME.md,
docs/mockups/ (final-amber.png is the locked visual).
Typecheck (backend + web) green. No behavior change to runtime code yet;
P2/P4/P5/P6 implement the feature on top of this.
Opening the app no longer auto-creates a blank tab or auto-restores/discovers
sessions as tabs. Instead it lands on a launcher (session chooser): a grid of the
host's running sessions as live preview thumbnails — pick one to open (replays its
full scrollback), or '+ New session'. Closing the last tab returns to the chooser.
- public/launcher.ts: mountLauncher() renders the chooser into the terminal area
(live xterm thumbnails via /live-sessions + /preview, 5s refresh), New session +
Manage link
- tabs.ts: drop restore()/syncLiveSessions() auto-tab behavior; constructor lands
on the launcher; rebuild() toggles launcher when tab count is 0; closeTab no
longer spawns a blank tab
- style.css: .launcher chrome (reuses the .mg-* card/grid/thumbnail styles)
Verified: fresh load → 0 tabs, chooser with thumbnails; Open → tab + chooser
hides; close last tab → chooser returns. 228 tests green, tsc + build clean.
The flat session list didn't tell you what each session was doing. Rebuild
/manage.html as a full-page grid where each card renders a LIVE preview
thumbnail — a read-only xterm showing the session's actual current screen,
scaled down like a screenshot — so you can recognize each at a glance.
- RingBuffer.tail(maxBytes): newest scrollback on chunk boundaries (no ANSI/UTF-8
split); GET /live-sessions/:id/preview returns {cols,rows,data} (no attach, so
it doesn't inflate watcher counts or keep sessions alive)
- manage.ts: card grid; per card a scaled read-only Terminal renders CLEAR+tail,
auto-refresh every 4s, click thumbnail/Open to join, Kill / bulk kill
- bundles xterm into manage.js (+manage.css linked in manage.html)
- ring-buffer tail tests
Verified: 3 sessions rendered as recognizable thumbnails (top / git log / ls),
colored, with status/age; click opens. 228 tests green, tsc clean.
The mirror looked broken because a backgrounded tab on one device still pinned
the shared PTY to its (default 80x24) size — so the device actively viewing got
a cramped terminal.
Fix: only an ACTIVELY-VIEWING client votes on PTY size.
- attachWs no longer seeds a default size vote (a join may be a hidden mirror)
- new 'blur' client message + clearClientDims(): a tab going hidden withdraws its
size vote (still mirrors output); show() re-casts it
- PTY size = min cols/rows across clients that have actually reported dims
- session/protocol tests cover hidden-mirror-doesn't-clamp + blur
Session manager (separate page, for the 'too many sessions' problem):
- GET stays; add DELETE /live-sessions/:id and DELETE /live-sessions[?detached=1]
- manager.killById(); LiveSessionInfo gains cols/rows
- public/manage.html + manage.ts: list/open/kill sessions, kill-all / kill-detached,
auto-refresh; 🗂 toolbar button; bundled as a 2nd esbuild entry
Verified: two concurrent clients mirror output + shared input; manage page
lists/kills (3→2→0). 225 tests green, tsc clean.
- tabs.ts: on open, syncLiveSessions() fetches /live-sessions and adds a tab for
each host session not already open → any device sees & mirrors everything
running on the host. Empty storage + no live sessions → one fresh tab.
activeSessionId() + openSession(id) helpers.
- share.ts: 🔗 toolbar button → QR + <origin>/?join=<id> for the active session.
- main.ts: ?join=<id> on load opens/focuses that shared session, then strips the
param. Mount share button (toolbar: 🔍 ⚙ ▦ 🕘 ⌨ 🔗📱).
- style.css: #sharemodal reuses the QR card/backdrop.
Verified in-browser: fresh device auto-discovered the host session and replayed
its scrollback; two concurrent clients (browser + ws) both received live output
(clientCount=2); share modal shows the join URL/QR.
keybar:
- add Ctrl+R (搜历史/\x12), Ctrl+L (重绘/\x0c), Ctrl+D (退出/\x04)
- each key now shows a short function caption under the glyph (self-documenting
on touch where tooltips don't appear); 17 keys total
- test/keybar.test.ts updated to 17 keys
cheat-sheet (new public/shortcuts.ts):
- ⌨ toolbar button opens a grouped reference of common Claude Code shortcuts
(general / editing / multiline / macOS / prefixes), each labeled with what it
does; keys also on the bottom bar are tagged 键栏
- Esc / click-outside to close; styled card with sticky header + accent tags
216 tests green; tsc + build clean.
- src/http/history.ts: listSessions() reads ~/.claude/projects/*/*.jsonl
(mtime-sorted, top 50), parseSessionMeta() extracts cwd + first user prompt
(pure, 4 unit tests); GET /sessions
- terminal-session: opts.initialInput (typed ~700ms after the shell is ready)
- tabs.newTabForResume(cwd,id): new tab in the project dir running
'claude --resume <id>'
- public/history.ts: 🕘 panel listing sessions (project · time · preview) with
Resume buttons
- Verified: /sessions returns 44 real sessions; panel lists project/time/preview.
216 tests green.
- M3: settings.ts (⚙ panel: dark/light/solarized theme + font size A-/A+),
persisted to localStorage; terminal-session.applyTheme; TabApp.applySettings
applies to all + new tabs
- M7: dashboard.ts (▦ overlay listing every tab with connection dot + folder +
Claude status; click a row to focus; live re-render while open);
TabApp.snapshot()/focusTab()
- Browser-verified: light theme renders + persists; dashboard lists tabs and
focuses on click. 208 tests green, typechecks + build ok.
- types/protocol: ClientMessage approve/reject; ServerMessage status.pending
- server: POST /hook/permission HELD until the client decides; approve/reject
ws messages resolve it with {hookSpecificOutput.decision.behavior allow|deny};
5-min timeout + release-on-disconnect fall back to Claude's own prompt
- manager.handleHookEvent threads pending flag
- setup-hooks: PermissionRequest uses the held curl (writes decision to stdout);
status events stay fire-and-forget
- FE: terminal-session approve()/reject() + pending state; tabs approval banner
(Approve/Reject) for the active tab's held request
- Tests: protocol approve/reject; integration ⑧ held→approve→allow. 207 green.
- Browser-verified: banner 'Claude wants to use Bash' → Approve → resolves allow.
- M5: 📱 toolbar button → modal with a client-side QR of location.origin
(shareable when opened via the LAN IP) + localhost tip
- M4: manifest.webmanifest + icon.svg + sw.js (network-first, never intercepts
/term or /hook) + registration in main.ts; apple-touch + theme-color meta
- Browser-verified: QR canvas renders, SW 'controlled', manifest linked,
no console errors. 199 tests green, build ok.
- terminal-session.ts: track SessionStatus (connecting/connected/reconnecting/
exited) + onStatus callback; FIX: wire onTitleChange (onTitle was in opts but
never bound — auto-title was dead)
- tabs.ts: per-tab status dot (color = connection state), unread flag set on
background output + cleared on activate, HTML5 drag-to-reorder (preserves
active tab, persisted)
- style.css: .tab-dot colors, .unread ring, .dragging/.drag-over feedback
- Browser-verified: green dot connected, unread ring after bg output, reorder
AAA|BBB→BBB|AAA persists across reload. 191 tests green, typechecks + build ok.
