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.
Relax the one-WS-per-session invariant (#5) so multiple devices mirror the
same live terminal (everyone sees output, anyone can type — tmux-style).
- types.ts: Session.attachedWs → clients Set + clientDims Map; add cwd;
SessionManager.list() + LiveSessionInfo
- session.ts: broadcast() output/exit to all clients; attachWs JOINS (no kick,
takes dims); detachWs removes one client, stamps detachedAt only when the last
leaves; setClientDims resizes PTY to the MIN cols/rows across clients
- manager.ts: join instead of kick; broadcast status; onExit drops only when a
client was attached; list() for discovery
- server.ts: GET /live-sessions; resize → per-client setClientDims; close →
detach one client; permission gate uses clients.size
- tests: rewrote session/manager tests for multi-client (join/broadcast/min-dims/
last-detach) + list(); 222 pass, tsc 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.
- title-util.cwdFromOsc7: parse cwd from OSC 7 (file:// URL); 4 unit tests
- terminal-session: register OSC 7 handler → cwd getter; opts.cwd → sent in the
attach frame on a fresh session
- protocol/types: ClientMessage attach.cwd (absolute path); validated
- session/manager/server: thread cwd → createSession spawn cwd (defaults homeDir)
- tabs: '+' (newTab) opens in the active tab's reported cwd, falls back to home
- Verified: server attach.cwd spawns there; cd /private/tmp → + → new tab pwd is
/private/tmp. 212 tests green.
- 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.
