Lock screen (main-window overlay, no second window):
- scrypt password verifier in <userData>/lock.json (per-write salt,
timingSafeEqual); salt/hash/password never leave the main process
- lock now / idle auto-lock / lock at startup, growing failure cooldown,
lock flags persisted so a quit-and-relaunch cannot bypass the lock
- locked shell and body portals go inert while sessions keep running;
menu accelerators (reload, DevTools, zoom) are swallowed while locked
- settings gains a Lock tab; all copy in zh-CN/zh-TW/en/ja
Security and stability:
- packaged builds ignore ELECTRON_RENDERER_URL / OT_UPDATE_URL (devEnv)
- renderer preload runs with sandbox: true
- unreadable known_hosts store fails closed instead of being overwritten
- connect-time secrets gated by the bookmark's auth method (connectPromptFor)
- ssh stream teardown is idempotent: PTY_EXIT broadcasts exactly once
- sysinfo polling is refcounted for split panes (forceStopPolling on close)
- session-log index entries are path-contained; settings store writes
atomically with EPERM/EBUSY retry
- sync-changelog tolerates CRLF checkouts (was a silent no-op)
- retry ssh2 host-key generation (flaky malformed key, ~1/500)
Tests: lock-store + lock-controller suites; transport-death PTY_EXIT e2e;
GitHub Actions CI (typecheck + 10 offline tests + build)
- upload: per-chunk buffer (ssh2 re-reads the overflow tail after the ACK;
a reused buffer silently corrupted every file >= ~254KB)
- close the cached SFTP channel on eviction, attach an 'error' handler,
close the download handle, time out execQuiet, fail partial deletes
- per-session StringDecoder for the ssh data plane (CJK mojibake), real
exit codes, safe replay truncation, zmodem abort/counter/timer fixes
- sysinfo: idempotent poll end, error routing, per-poll watchdog, proc(5)
CPU total; expand cd ~/$HOME/%USERPROFILE% paths; log sanitizer fixes
- security: will-navigate guard, central IPC sender check, scheme
allowlist for openExternal, single-instance else branch, layout id and
log-name whitelists, custom theme sanitizing, atomic JSON writes with
EPERM retry in store.writeJson
- updater: per-attempt feed choice, quitAndInstall relaunch, dev guard,
update-state getter
