The current foundation provides strict TOML configuration, file-backed secrets, API/local root mapping, fail-fast permission and sparse-file probes, a durable SQLite command inbox, bounded one-writer WebSocket output, registration-first authentication, heartbeat handling, duplicate-command acknowledgements, and indefinite capped exponential reconnect with optional jitter.

archive-client --config /etc/archive-control/client.toml --check-config
archive-client --config /etc/archive-control/client.toml --mode archive

--mode accepts only archive or cache and overrides the configured role. Secrets must be regular files without group/world permissions. The daemon never stores them in SQLite or sends the shared token after registration.

This foundation currently executes heartbeat and state-snapshot commands. Other mutation commands are durably rejected as unsupported until their service and file-operation executors are added; they are never falsely acknowledged as accepted.

Run tests and build using containers:

docker build --target test -t archive-clients-test .
docker run --rm archive-clients-test
docker build -t sodium/archive-clients:dev .

Generated bindings are pinned to archive-control-proto commit 4ec852014dad74606d4078b3ae1aa208c814b033.
