+- Proxy helper launches directly with `shell: false`; passwordless launch uses the main-owned paired session only through the helper's required `-k` argument.

 - Never add download/install/replace logic, arbitrary URLs, redirect following, shell scripts, broad process killing, hardcoded bridge secrets, or credential-bearing renderer state.
 - Synthetic tests only: never use a real tenant or Alta session.

+- Proxy launch is a direct, detached `spawn` of the fixed helper with `shell: false`. APT passes the main-process-only paired Alta session through the helper's supported `-k` cookie mode so users are not prompted for Alta credentials again. The cookie never crosses renderer IPC, enters a shell, or reaches logs, files, tracked process metadata, or UI state; it is necessarily present in the helper process arguments because the external helper exposes no pipe/stdin credential interface. Stop actions can target only children owned by this app.
 - Updates are **check-only**. APT checks the exact GitPeji release API and can open only `https://git.pejicorp.com/peji/Alta-Proxy-Tool/releases` in the system browser. It never downloads, replaces, or executes an update.

+## Accepted passwordless proxy exception

+Zac explicitly requires the paired-extension **Connect → select camera → Start Proxy** flow without re-entering Alta credentials. The external `aware-cam-proxy.exe` helper supports cookie authentication only through `-k`; it exposes no stdin, named-pipe, environment-variable, or credential-file interface. APT therefore passes the validated main-owned session directly to the fixed helper as one argv value. This exception remains bounded by direct `shell: false` spawn, trusted-device allowlisting, no renderer/IPC credential parameter, no logs/files/shells, redacted launch errors, safe tracked metadata, and synthetic regression tests.
