* perf(terminal): release oversized backing strings behind pending controls * test(terminal): record reproducible pending-storage gate evidence * perf(terminal): own retained control fragments with a fast copy primitive The pending-control ownership landed with a charCodeAt block copier (10 us at 4 Ki, 170 us at 64 Ki), so it needed a "copy only when discarded output dominates the tail" gate to stay affordable. That gate was the whole cost problem: on adversarial streams it fires every chunk and pays the slow copy (+45% on 16 Ki ANSI chunks, +81..111% on 194 Ki status chunks), and it also skipped ownership on fragments too small to be sliced strings anyway. ownRetainedString replaces it with a Buffer utf16le round trip (0.57 us at 4 Ki, 21.9 us at 64 Ki) and returns anything below V8's SlicedString kMinLength unchanged. Buffer is absent in the renderer and on mobile, so the copier is resolved once behind a lone-surrogate round-trip self-check and falls back to the block copier. With a ~1 us copy the gate is unnecessary: ownership is now unconditional at all three retention sites and the adversarial cases land within noise of the un-owned parsers. The three forced-GC threshold fixtures are replaced by one forced-GC test for the primitive plus deterministic spy assertions that each site routes its retained value through ownRetainedString. All fidelity and differential coverage is kept. * fix(terminal): escape the NUL in the round-trip probe A raw NUL byte in the source made git treat the file as binary, so its diffs and blame were unreadable. Escapes are equivalent at runtime.

Also in the box:
- Quick open — Search across worktrees, files, agents, commands, and repo context without leaving your flow.
- Account switcher & usage tracking — See Claude and Codex usage and rate-limit resets, and hot-swap accounts without re-logging in.
- Rich repo previews — Preview Markdown, images, PDFs, and repo docs in the workspace.
- Computer Use — Let agents operate desktop apps and visible UI when a workflow needs real interaction.
- Notifications and unread state — Know when an agent finishes or needs attention, then mark threads unread to come back later.
- And many, many more — we ship daily, so this list is perpetually behind. The changelog is the real feature list.
