The largest defect was not the one the plan named. Every control character was being dropped before it reached the PTY — ctrl-c, ctrl-d, ctrl-a, ctrl-r, not just ctrl-k — because terminal_key_from_parts required a key_char and GPUI reports none for a control chord, since ctrl-k produces no printable character. Verified with `cat -v`, which now prints ^K^A^R; ctrl-c interrupts a sleep and ctrl-d ends a heredoc. The engine had always encoded these correctly; nothing ever handed them to it. The binding shadowing was real too. OpenPalette was on secondary-k, which is ctrl-k on Linux, and GPUI stops dispatching once a binding claims an event, so readline's kill-line was unreachable in every pane. Pane selection sat on alt-1..6, which readline reads as a digit argument, and focus movement on alt-arrows, which is word motion in most terminals. Bindings now live in keymap.rs with the rule written down and tested: no binding may be a bare control character or a bare Meta sequence, because those are what a terminal application actually receives. A leader chord was considered and rejected — GPUI parks a chord prefix for a second and drops it if focus moves. Also in this pass: - Paste on secondary-shift-v, through the engine's bracketed-paste path so a shell that asked for bracketed paste is told this is a paste. secondary-v would have been ctrl-v, which readline reads as quoted-insert. There is no matching copy: the engine has no selection yet, and a key that copied the whole screen would not be the same feature under the same name. - A scroll wheel on the terminal surface. Shift+PageUp was the only route to scrollback, which is not something anyone guesses. - Restart and Terminate. RuntimeRegistry::shutdown existed and was called only from its own crate's tests, so nothing in the application could ever stop a PTY. Terminate is the literal words with a confirmation naming the pid, per decision 0010, never a close icon; restart keeps the pane and replaces the process, per decision 0011. - A dead or faulted pane now says so over its stale screen instead of looking idle, and typing into a pane with no terminal explains where the keystroke went instead of silently discarding it. - The twelve reachable .expect panics on live-terminal state are gone. A pane can outlive its runtime — failed spawn, terminate, restored snapshot — and every one of those paths used to be a panic in the middle of a paint.

Lumbridge
Lumbridge is a fast, local-first workspace and terminal multiplexer for agentic engineers. It will run coding harnesses side by side, preserve their sessions, connect rich agents through ACP, and show trustworthy account and usage context without forcing users into one model vendor.
The first supported desktop platforms are:
- macOS (Apple Silicon first, Intel when CI capacity is available)
- Ubuntu Linux
- Omarchy and compatible Arch Linux systems
Lumbridge is free and open source under Apache-2.0. Releases will be published as installable binaries; building from source will remain supported.
Status
This repository is in architecture and vertical-slice phase. The installable binary is still a scaffold, while the isolated native UI spikes now exercise an interactive 20/60/20 workspace backed by six live comparison surfaces, and the root workspace contains the first bounded local PTY, runtime actor, VT engine, and capability-gated workspace command boundaries. The GPUI slice shows a responsive one-, three-, or five-panel workspace—five on a 3440 px ultrawide— where every panel owns its own context, work surface, and decision shelf. One panel contains a styled actor-owned VT session and five comparison surfaces remain deterministic. Retained-history navigation is wired. The usage footer is a live strip over an append-only ledger with provenance, fed by two real adapters: Codex's documented quota surface and Claude Code's session transcripts. A harness with no adapter renders an explicit gap rather than a zero. We are still validating terminal text selection and mouse input, standalone runtime IPC/durability, ACP integration, and packaging before a large implementation.
Product shape
- A native desktop shell with tabs, panes, workspaces, worktrees, diffs, and an agent-aware footer.
- A Rust session runtime that survives UI restarts and can later run headless.
- ACP-native integrations where available, with supervised PTYs as the universal fallback for any CLI harness.
- First-class harnesses for Claude Code, Codex, DeepSeek Harness, Pi, Hermes, OpenClaw, Goose, Gemini CLI, and OpenCode.
- Subscription login owned by the upstream harness, plus separate BYOK provider profiles for OpenAI, Anthropic, Gemini, Groq, Cerebras, DeepSeek, and more.
- Usage history, burn rate, reset windows, and forecasts with visible data provenance instead of invented precision.
- Optional first-class Buzz channels, messages, agents, and confirmed redacted pane sharing without making Buzz a requirement.
- An optional Lumbridge Harness that can suggest, coordinate, and—with explicit execution capability—manage agents through the same audited command plane as the human UI. Lumbridge remains useful without it.
Start with the product spec, architecture, research map, and captured upstream revisions. The native UI choice is intentionally open; see the measured decision plan.

The accepted local/remote boundary is recorded in
decision 0003. The two
native shell candidates live in spikes/, with results tracked in
the UI scorecard.
The signed-protocol and pane-sharing boundary is in
the Buzz integration design.
