feat: detect Conductor host instead of showing Unknown - #669
Merged
Conversation
Conductor (conductor.build) runs Claude Code as a headless, TTY-less subprocess of its own runtime, so process discovery never finds a terminal and TERM_PROGRAM is unset — its sessions showed as "Unknown" with no jump-back. Recognize Conductor from the identifiers it stamps into the agent environment (CONDUCTOR_SESSION_ID, which equals the Claude Code --session-id, plus CONDUCTOR_WORKSPACE_ID and __CFBundleIdentifier=com.conductor.app), checked before TERM_PROGRAM for the same env-inheritance-leak reason as the Claude.app check. Add a process-tree fallback via the conductor-runtime sidecar / Conductor.app ancestors, and register the com.conductor.app descriptor so jump-back brings the Conductor app forward (app-level, like Claude.app — Conductor hosts each agent in its own window with no per-session deep link). Mirrors the Zed detection pattern. Adds two ClaudeHooks tests and README entries (EN + zh-CN).

Conductor (conductor.build) runs Claude Code as a headless, TTY-less subprocess, so ps/lsof process discovery never sees it — the same shape as Claude Desktop (Octane0411#510). ProcessMonitoringCoordinator had no app-level liveness fallback for Conductor, so SessionState.markProcessLiveness evicted these sessions two polls after they appeared: the session showed up correctly tagged "Conductor", then vanished seconds later. Mirror the Claude Desktop fix: keep sessions tagged terminalApp == "Conductor" in the alive set while Conductor is running, letting completed sessions expire after the staleness window. Adds isConductorAppRunning() and conductorStalenessTimeout, plus a SessionState regression test pinning the liveness contract the fallback relies on.

Normalize terminalApp before matching Conductor sessions.
If a persisted JumpTarget.terminalApp is "conductor", this raw comparison excludes the session from aliveIDs. SessionState.markProcessLiveness(aliveSessionIDs:) then can mark the hook-managed session ended after two liveness misses. Use supportedTerminalApp(for:) before comparing with "Conductor".

Test the Conductor-specific coordinator path.
SessionState.markProcessLiveness only consumes aliveSessionIDs. It does not inspect terminalApp or the Conductor bundle identifier. This test passes even if ProcessMonitoringCoordinator never adds Conductor sessions to aliveSessionIDs.
Move this test to the coordinator test target, inject the Conductor running state or extract a pure helper, and assert the generated alive-session set.

CONDUCTOR_SESSION_ID / CONDUCTOR_WORKSPACE_ID were checked with `!= nil`, which also matches an empty string, so an empty marker would classify the session as "Conductor" without a valid identifier. Require a non-empty value on both markers; the __CFBundleIdentifier check is unchanged. Adds a ClaudeHooks test asserting empty markers are not treated as Conductor.

…ging `launch-dev-app.sh` and `package-app.sh` ran `generate_brand_icons.py` on every invocation, rewriting the committed iconsets in place. The renderer is deterministic per machine, but PNG bytes differ between Pillow versions even when every pixel is identical, so on any machine whose Pillow differs from the one that produced the committed files each dev launch left 14 modified PNGs in the worktree. That blocked `git pull` and leaked into unrelated commits (Octane0411#669 carried a churn-and-revert pair; Octane0411#678 shipped the 14 re-encoded files). `package-app.sh` had the same issue with `dmg-background.png`, which additionally depends on the machine's fonts. Both scripts now package the committed `OpenIsland.icns` and DMG background as-is and fail with a pointer to the generator if either is missing. Re-rendering is opt-in: `launch-dev-app.sh --regenerate-icons` and `OPEN_ISLAND_REGENERATE_BRAND_ASSETS=true zsh scripts/package-app.sh`. Assets/Brand/README.md documents the workflow and the expected diff after regenerating on a different machine.

Problem
Sessions launched inside Conductor show up in the island as
Unknown, with no jump-back. Conductor runs each agent (e.g. Claude Code) as a headless, TTY-less subprocess of its own runtime — not inside a terminal emulator — so:TERM_PROGRAMis unset,which is exactly the "no signal → Unknown" path. This mirrors the gap that #644 closed for Zed.
What Conductor actually exposes
Inspecting a live Conductor-hosted process, Conductor stamps its own identifiers into the agent environment:
and the process ancestry is
agent → conductor-runtime sidecar (…/com.conductor.app/…) → /Applications/Conductor.app/Contents/MacOS/conductor.Change
Recognize Conductor as a host, following the exact pattern of the Zed change (#644):
ClaudeHooks.inferTerminalApp— detect Conductor from the environment (CONDUCTOR_SESSION_ID/CONDUCTOR_WORKSPACE_ID/__CFBundleIdentifier == com.conductor.app). Placed before theTERM_PROGRAMswitch, for the same env-inheritance-leak reason as the existingClaude.appcheck.ActiveAgentProcessDiscovery.recognizedTerminalApp— process-tree fallback: the agent's ancestors (theconductor-runtimesidecar and theConductor.appbundle) resolve toConductor.ProcessMonitoringCoordinator.supportedTerminalApp— canonicalizeconductor→Conductor.TerminalJumpService— register thecom.conductor.appdescriptor and an explicit jump case. Conductor hosts each agent inside its own window with no per-session deep link, so jump-back brings the Conductor app forward — same rationale (and behavior) as the existingClaude.appcase.README.mdandREADME.zh-CN.md.Support level
App-level (activate Conductor), matching how
Claude.app/Codex.app(without a thread id) are handled. Deeper targeting (a specific workspace tab) would need a Conductor deep-link/API and is intentionally out of scope here — see the related process-tree approach in #453.Testing
swift build— clean.swift test(viascripts/test-clt.shon a Command Line Tools-only setup) — 370 tests / 39 suites pass, including two newClaudeHooksTestscases: detection viaCONDUCTOR_SESSION_IDand via__CFBundleIdentifier.OpenIslandHooksbinary through the running app bridge — the session registers withjumpTarget.terminalApp = "Conductor"(baseline wasUnknown) and the workspace name (nukualofa) resolves. Jump-back (open -b com.conductor.app) brings Conductor frontmost.AI-assisted; reviewed and verified by the author.
