- Caddyfile: access and error logs replace the /i/<code> segment and every query string with REDACTED
(regexp filter on request>uri); Authorization stays redacted by default. Deferred response headers:
Content-Security-Policy, X-Content-Type-Options, X-Frame-Options, Referrer-Policy.
- Pi compose: caddy as uid 10002 with group 1000, read-only root, cap_drop ALL plus NET_BIND_SERVICE
(needed to exec the image's file-capability binary), tmpfs /config and /tmp; install.sh sets /certs
0750 1000:1000 and Caddy's /data to 10002.
- deploy.sh and install.sh print the pulled image digests and append them to /opt/kvitt/deployed-digests,
warning when a recorded tag changed digest; the workflow prints the pushed digests; kvitt_cicd needs
only write:package.
- Dev stack: up.sh stages only fcm-service-account.json into infra/dev/secrets/ (git-ignored), mounted
read-only at /secrets.
- README: restricted cert-sync key required (plain root key not acceptable), remote_ip and log checks,
APK download note, owner decisions (backup encryption, APK limit, key form, token scope), overhaul lines.
