Entrypoint drops the capability bounding set and sets no_new_privs. Security docs
and spec no longer claim the agent can't reach the secrets; docker exec fallbacks
use a clean environment. PLAYWRIGHT_ENABLED drops the nested compose default.
Tests pin the Dockerfile's Playwright install step and the compose model fallback.
INSTALL_PLAYWRIGHT=true installs @playwright/mcp@0.0.82 globally and runs its own playwright dependency's installer (install --with-deps chromium) into /opt/ms-playwright, readable by all users. The build fails if playwright-mcp --version does not run.
Two-stage build, agent tools, Node 24, claude CLI, data dirs owned by app, DOTNET_EnableDiagnostics=0. Adds the MCP spec's deferred test that the Dockerfile's PLAYWRIGHT_MCP_VERSION equals PlaywrightPreset.DefaultPackage.
Spec change: the image keeps root as its user and the entrypoint drops to app with setpriv. With USER app, compose's docker-init (PID 1) runs as app and its /proc/1/environ exposes every secret to the agent's bash. The spec also lists the csprojs the restore layer copies (GoogleCalendar, Mcp, Scheduler included) and sets HOME=/home/app in the image.
