- 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.
