feat(shell): compact the Status sidebar - #1004
AutanaSoft wants to merge 14 commits into
Conversation
Add a shared, memoized native mode reader and refresh Shell after review-mode changes. Render ON, OFF, and unknown states in the sidebar and compact footer with race-safe lifecycle handling.
📝 WalkthroughWalkthroughThe shell sidebar now renders compact, responsive project, model, context, usage, and integration groups. Usage windows use gauges and percentages. Tests cover width limits, Unicode values, sanitized status text, and rail usage precedence. ChangesCompact status sidebar

Use platform-aware basename extraction.
buildShellBarModel passes the session working directory to both renderers. On Windows, the slash-only split returns C:\workspace\project instead of project. The sidebar shows the full path, and the overflowing bottom bar has the same defect through compactModel.
Import basename from node:path and return basename(cwd).
Add regression coverage for both renderers. Use C:\workspace\project on Windows and a POSIX path on other supported hosts. Assert that both renderers display project and not the parent path.
As per path instructions, “Behavior changes here must ship with their tests in the same PR.”

Let the shared resolver own the status deadline.
The production caller at Line 8774 passes AbortSignal.timeout(RDD_STATUS_TIMEOUT_MS). The shared resolver also creates an internal timeout. The caller timeout starts first, so it normally wins and is classified as caller cancellation. The resolver then does not memoize the timeout result.
During a native outage, each primary agent start can stall for three seconds and launch another native read instead of reusing the 30-second failure memo. Remove the explicit timeout at Line 8774. Pass only a genuine lifecycle cancellation signal.
