- agent_loop.py: create log dir with mode 0700 and enforce it on
existing dirs; open log files with mode 0600; chmod state file
to 0600 after every write. Prevents other local processes from
reading agent output (which may contain credential paths) or
tampering with the state file's pid field.
- ci/main.go (TestAndroidFirebase): replace
echo "$FIREBASE_SA_KEY" > /tmp/key.json
with bash process substitution
--key-file=<(echo "$FIREBASE_SA_KEY")
The key is now passed via a file descriptor — it never touches
disk, so it cannot be stranded by a failed gcloud auth call or
snapshotted into the Dagger layer cache.
- ci.yml / deploy.yml: add "Cleanup TLS credentials" step
(if: always()) at the end of every job that calls
setup_dagger_remote.sh. Removes /tmp/dagger-tls,
/tmp/stunnel-dagger.conf, /tmp/stunnel.pid from the self-hosted
runner after each job, so client certs do not accumulate between
job runs.
