# Drop privileges to the agent user before exec'ing molecule-runtime.
# claude-code refuses --dangerously-skip-permissions when running as
# root/sudo for safety. Without this entrypoint, every cron tick fails
# with `ProcessError: Command failed with exit code 1` and the agent
# logs `--dangerously-skip-permissions cannot be used with root/sudo
# privileges for security reasons`.
#
# Pattern matches the legacy monorepo workspace-template/entrypoint.sh:
# fix volume ownership as root, then re-exec via gosu as agent (uid 1000).

# Boot-context snapshot — emitted on EVERY container start, including
# every restart of a crash-loop. Lets `docker logs` answer "what env
# was actually present?" without having to docker exec into a dying
# container. Logs NAMES of auth-relevant env vars, never VALUES. Fires
# twice (once as root pre-gosu, once as agent post-gosu) so an operator
# can see whether a value was lost across the privilege drop.
# Keep the env-name list in sync with adapter.py's _AUTH_ENV_AUDIT —
# the same set of vendors should be audited from both sides.
