Implements the Tier-1 pane subsystem from D-006: spawn / list / focus / close / write / resize / tail commands, plus pane.spawned / output / exit / resized / focused / closed events. PaneRegistry owns per-pane PtySession lifecycles and id generation (p_N); a DaemonEventSink seam keeps pane code decoupled from the IPC server package. DaemonServer.broadcast() fans events out to every connected client. Per-client subsystem/id filtering (`tail --filter pane:p_7`) is deferred — Tier 1 broadcasts everything and the subscriber discards. Panes carry a `kind:` field (terminal | claude). Step 7 (builtin.claude) adds the claude-specific pane flow on top of this generic substrate — the subsystem itself stays neutral. 14 new core tests: registry unit coverage (spawn → pane.spawned event, output → base64 events, write/resize/close round-trips, idempotent close, claude kind on the wire) plus dispatcher coverage (argv validation, unknown-id → not-found, text vs bytes_b64, etc). All 37 core tests pass in ~3s under test-core. Co-Authored-By: Claude <noreply@anthropic.com>
clide
A Flutter desktop IDE for Claude Code. Markdown-first content, pql-powered queries, canvas and graph surfaces, a Go sidecar handling PTYs / subprocesses / git / pql. Claude drives the UI through a clide CLI.
Currently pre-v2.0, scaffolding. The north-star design lives in docs/initial-plan.md; architectural decisions are captured in docs/ADRs/. The Python Textual v1.2.0 implementation is archived under legacy/ for reference.
Three surfaces, one tool
app/— Flutter desktop application (Linux / macOS; Windows is a stretch).sidecar/— Go sidecar/CLI, single binary with two modes:clide <subcommand>(one-shot for Claude) andclide --daemon(long-running sidecar for the app). Owns PTYs, subprocesses, file watchers, git, pql invocations.pql— external supporter tool. clide wraps it for every query surface; never re-implements it.
Why the rebuild?
The Python Textual implementation (legacy/) proved the pane model but capped at terminal-only rendering. A short-lived experiment (claudian, April 2026) explored an Obsidian-plugin approach and was abandoned because Obsidian is Electron, and the user's history with terminal-in-Electron ruled that host out.
Flutter desktop resolves both constraints: native Skia rendering avoids Electron's failure modes, xterm.dart gives us a solid terminal surface, and the pane model can be rebuilt natively. The Obsidian ideas worth keeping (canvas, graph) fold in; everything else (vault concept, inline query tables, plugin ecosystem inheritance) doesn't.
Status
No build yet beyond the repo scaffold. Tier 0 acceptance: sidecar daemon runs, Flutter app connects, empty IDE shell appears with placeholders.
