The footer showed invented percentages. It now shows what two harnesses actually report, or says it does not know. lumbridge-core gains an append-only per-profile UsageLedger and a projection that labels every derived value estimated, withholds a burn rate from a single sample, withholds a window fraction with no reported ceiling, withholds an exhaustion estimate that lands after the reset, and reports an expired window as rolled over rather than freezing its last percentage. A missing fact renders as missing, never as zero. (0012) lumbridge-harness is the impure side: processes, clocks, and untrusted wire text in, observations out. Three adapters: - Codex's account/rateLimits/read over the app-server's JSON-RPC stdio. The client cannot express a request outside a two-variant enum and answers every server-to-client request with -32601, so a harness asking Lumbridge for a credential is refused by construction. (0013) - Claude Code's session transcripts, as a byte-offset tail follower that reports nothing until the backlog is read to EOF — a partially-read backlog is indistinguishable from a burst of spend, and the first run against 20 MB reported forty-six billion tokens an hour. The parser models four counters, so the conversations in those files are not representable. (0014) - Claude Code's five-hour and seven-day subscription windows, via a bridge installed as its statusLine command. 0014 had claimed no such surface existed; it does, and the record is corrected in place rather than quietly edited. Lumbridge does not read the OAuth credential to call the account usage endpoint, which is what comparable tools do — AGENTS.md forbids it, and 0015 says so rather than leaving the gap unexplained. Also in here: a capability-check ordering fix in the workspace reducer, where the applied-request replay table was consulted before the capability check and so answered questions the caller had no right to ask; the GPUI spike wired to the live probes with per-harness gauges and provenance chips; and a launcher that matches its own window by PID, because GPUI sets WM_NAME but not _NET_WM_NAME and a title match never succeeded.

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.
Scaffold
bacon # continuous check; t tests, c lints, v runs the full gate
cargo xtest # fast isolated tests with nextest
./scripts/ci.sh # format + strict Clippy + tests + doctests

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.
