Root cause of the recurring "turn.credentials → namespace_not_configured" on a
distant node: at converge the gateway resolves its TURN secret from the
namespace rqlite, and on a slow/just-restarted node that read fails ONCE, so
the gateway is written with TURN disabled. Removing the node is not a fix — the
software must tolerate a slow read.
Two-part fix (complements e7ed718's "don't blank a warm config"):
- RETRY the secret read (5×2s) at converge so a node whose rqlite is still
syncing waits for it to land instead of writing an empty block once. A
genuine decrypt failure still exhausts the retries → unresolved → the
running config is preserved.
- CACHE the resolved secret into the node's own cluster-state.json
(applyResolvedWebRTCToState), so the NEXT cold start reads it from disk —
chooseRestoreWebRTC is state-first and short-circuits before the DB. The
state struct already had TURNSharedSecret "for cold start" but nothing
populated it; now it's filled on every successful resolve (only rewritten
on change). Each node self-heals its own cache; nothing new is sent
cross-node.
cluster-state.json now carries the TURN secret, so both writers (local
saveLocalState and the remote SaveClusterState) are tightened to 0600 + chmod.
Stale-secret self-heals: disable/enable webrtc re-pushes every node's config
and the next converge re-caches the new value.
Dual-reviewed: code-quality APPROVED; security SECURE after the remote-write
0600 fix. Tests: cache populate + short-circuit, no-change, turn-only node.
- Implement `resolveStealthCert` to use existing `*.<baseDomain>` wildcard certificates instead of dynamic Caddyfile provisioning.
- Avoids EROFS errors caused by `ProtectSystem=strict` on the orama-node service.
- Add strict validation to ensure stealth hosts are single-label subdomains covered by the wildcard.
- Add `turn_stealth_domain` to gateway config for stealth TURN support
- Introduce `turn_discovery` in `sni-router` to auto-discover per-namespace routes
- Add database migration to enable stealth TURN per namespace
- Document ephemeral state API in `SERVERLESS.md`
- add `secrets_encryption_key` to gateway config for serverless secrets
- implement durable TURN secret persistence to prevent config regen outages
- add regression test for gateway config loading and field mapping
- Add logic to reconcile gateway configuration drift for running instances
- Prevent unnecessary restart loops by verifying on-disk config state
- Add unit tests to validate synchronization logic and prevent regressions
- Add `namespace_push_config` table for per-namespace provider settings
- Introduce `cluster_secret_path` to enable deterministic JWT signing and
AES-256-GCM encryption for push credentials
- Update gateway config to support per-namespace overrides of push
notification providers (ntfy/Expo)
- Bump version to 0.122.3
