 Pane titles add a small quiet-output marker after roughly three seconds without output. The marker means a pane produced output and then went idle; it does not mean the process exited or completed its task.

+## Auth Profiles
+
+GridBash can launch Claude and Codex with isolated auth/config directories. It discovers profiles from:
+
+```text
+GRIDBASH_AUTH_HOME > CLAUDE_PROFILES_HOME > [auth].home > %USERPROFILE%\.claude-profiles
+```
+
+Claude profiles launch with `CLAUDE_CONFIG_DIR=<profile-dir>`. Codex profiles launch with `CODEX_HOME=<profile-dir>`.
+
+Auth settings controls:
+
+| Input | Action |
+| --- | --- |
+| Tab | Switch Settings tabs |
+| Up / Down | Move through auth profiles |
+| d | Set selected profile as the GridBash-wide default for its kind |
+| n | Create a profile directory |
+| l | Open the selected profile's login command |
+| r | Refresh local account and usage status |
+| Esc / q | Close settings |
+
+Usage status is best-effort. GridBash reads local auth metadata, masks account emails, and uses short-timeout `curl.exe` requests only while the Auth settings view is refreshed.

+# Integrate native auth manager
+
+Date: 2026-07-07
+Release target: unreleased
+
+## Summary
+
+- Integrated the native Claude/Codex auth profile manager with current `main`.
+- Preserved the existing live pane usage labels while making them prefer the auth directory applied to a pane.
+
+## What Changed
+
+- Added `[auth]` config with per-kind defaults and local auth profile discovery.
+- Added an Auth tab to Settings for browsing profiles, creating profile directories, setting defaults, refreshing status, and launching login.
+- Tagged built-in Claude/Codex profiles with `agent_kind` so auth defaults can set `CLAUDE_CONFIG_DIR` or `CODEX_HOME` at launch.
+- Pane titles now include launch profile and auth profile metadata while keeping current usage labels.
+- Usage monitoring now follows the applied native auth directory before falling back to existing profile/default auth lookup.
+
+## Why It Matters
+
+- Multiple Claude and Codex accounts can run through GridBash without manually exporting auth environment variables.
+- Usage labels stay accurate for panes launched with native auth defaults.
+- The Settings/Profile flow from current `main` remains the base behavior.
+
+## Validation
+
+- Ran `cargo fmt`.
+- Ran `npm test` with 55 passing tests and 1 ignored interactive ConPTY smoke test after rebasing onto the latest `origin/main`.
+
+## Release Notes
+
+- Added native Claude/Codex auth profile management in Settings.
+- Added GridBash-wide auth defaults for built-in and kind-tagged custom agent profiles.
+- Pane headers now show launch profile/auth profile metadata alongside existing usage labels.
