The terminal was xterm with one addon (fit) and a single fit() call at connect, so the shell kept whatever cols/rows it was born with. Drag a panel wider and the PTY never heard about it — anything drawing a full screen (an agent TUI, top, vim) rendered into a box that no longer matched the one you were looking at. A ResizeObserver now refits and sends pty:resize, coalesced to one fit per frame because dragging an edge fires continuously and each fit reflows. Scrollback goes from xterm's default 1000 lines to 10,000 — one long agent turn was enough to lose the start of it. Addons, all off the shelf and none previously loaded: - webgl — the renderer, and the reason fast repainting feels smooth rather than syrupy. Guarded twice: construction can throw where there is no GL context, and the context can be lost later, so both paths fall back to the DOM renderer instead of a dead canvas. - unicode11 (+ allowProposedApi) — correct widths for emoji, CJK and box-drawing. The default unicode 6 tables are why agent TUI frames sit a column out. - web-links — URLs in output are clickable. - search — with a find bar on Ctrl/Cmd-Shift-F. Not plain Ctrl-F: that is forward-one-char in readline and emacs, and swallowing it would break every shell in the app. - serialize — installed for exact-state replay, not yet wired. Also reports the shell's own title (OSC 0/2) and the bell through new optional callbacks, so a panel can show what is running in it and flag a finished turn you weren't watching. Nothing consumes them yet. Unrelated but found by this run: three origin-validation tests were failing. Not from this change — ALLOW_ANY_ORIGIN=true in .env, added last night, and Bun loads the host .env into tests, so the kill switch had silently turned the assertions into no-ops. The test now pins both escape hatches off, since its whole job is asserting the checks reject things. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
