- endpoint-level: a deployment/program edit via /config/* leaves castle.yaml
globals byte-identical (the exact regression that shipped — the endpoints were
tested but nobody asserted globals survived)
- write_program_file leaves globals untouched (core)
- /secrets/info reports the backend
Still uncovered (tracked): castle mesh CLI, direct-read refactor (dns/stacks),
backend-aware doctor, and all frontend (no test runner configured).
Root-cause hardening for the dropped-globals bug: config edits went through the
full-document save_config, which rewrote castle.yaml globals (+ every resource
file) on every deployment/program edit — so an unmodeled global (role, secrets)
was dropped.
- add write_deployment_file / write_program_file: persist ONE resource file,
never touching globals or other resources
- config_editor deployment/program save/delete/enable now use those instead of
save_config, so a deployment edit can't rewrite castle.yaml
- save_config now preserves ANY unmanaged top-level global (not just secrets)
- _aggregate_yaml surfaces role + secrets (raw-yaml round-trip completeness)
- tests: scoped write leaves globals byte-identical; unmanaged global survives
Verified live: editing lakehouse via the endpoint leaves castle.yaml unchanged.
save_config rewrites castle.yaml from scratch and only re-emitted gateway/repo/
roots — so any config save (dashboard deployment edit, config_editor) silently
STRIPPED top-level 'role' and the 'secrets:' backend block. Effect: the node
reverted to a file-backend follower, the vault stopped resolving, and a
subsequent apply baked <MISSING_SECRET> into service env (hit castle-lakehouse).
Now re-emit role (from config) + preserve the secrets block (read from the
existing file, since it's not modeled on CastleConfig). Regression test added.
- add static 'role' (authority|follower) to NodeConfig/CastleConfig, wired from
castle.yaml through the registry to the mesh wire; civil pinned authority
- castle-presence: TTL KV bucket each node renews (churn signal); delete-on-stop
- castle-config: authority-gated get/put + change-watch SSE (follower reconcile
hook hangs off it)
- bound the NATS drain on stop() so shutdown can't hang
- tests: role config/registry round-trip, wire round-trip, role write-gating
Single-node verified; follower reconcile pending the second node.
