## Changelog

#### StatefulSet for SQLite with Persistence

This release fixes the multi-attach volume error when running multiple replicas with SQLite storage mode.

#### What Changed

- When using `storage.mode: sqlite` with `storage.persistence.enabled: true`, Bifrost now deploys as a **StatefulSet** instead of a Deployment
- Each pod gets its own dedicated PersistentVolumeClaim (e.g., `data-bifrost-0`, `data-bifrost-1`, `data-bifrost-2`)
- A headless service is created for StatefulSet DNS resolution
- HorizontalPodAutoscaler now correctly references StatefulSet or Deployment based on storage configuration

#### Who Is Affected

- Users running SQLite mode with persistence enabled and multiple replicas
- Users upgrading existing SQLite deployments need to migrate (see below)

#### Who Is NOT Affected

- Users running PostgreSQL mode (`storage.mode: postgres`) - no changes, still uses Deployment
- Users running SQLite without persistence (`storage.persistence.enabled: false`)
- Users running SQLite with an existing PVC claim (`storage.persistence.existingClaim`)

#### Migration Guide for Existing SQLite Deployments

Since Kubernetes doesn't allow in-place conversion from Deployment to StatefulSet, you need to:

1. Back up your data (if needed)
2. Uninstall the existing release: `helm uninstall bifrost`
3. Delete the old PVC: `kubectl delete pvc bifrost-data`
4. Install with the new chart version: `helm install bifrost bifrost/bifrost --set image.tag=<latest-image>`

**Note:** For production high-availability setups, we recommend using PostgreSQL mode which scales horizontally without these concerns.

## Changelog

- Synced helm `values.schema.json` with transport `config.schema.json` — fixed virtual key and budget drift:
- Removed `required: [mcp_client_id]` constraint on `virtualKeys[].mcp_configs[]` items — canonical schema accepts either `mcp_client_id` (DB form) or `mcp_client_name` (config-file form, resolved to ID at startup)
- Added `mcp_client_name` as an allowed property on `virtualKeys[].mcp_configs[]` items
- Added `calendar_aligned` (boolean) on `virtualKeys[]` — field now lives on the virtual key, applies uniformly to all budgets under it
- Removed stale `budget_id` from `virtualKeys[]` — `TableVirtualKey` has no `BudgetID`; budgets link via foreign key from the budget table
- Removed stale `calendar_aligned` from `budgets[]` — moved to virtual key level

## Changelog

- Added `bifrost.cluster.grpc` block for the cluster gRPC counter-sync transport (enterprise):
- New values: `bifrost.cluster.grpc.port` (default `10102`) and `bifrost.cluster.grpc.dialTimeoutSeconds` (default `5`).
- Rendered into `cluster_config.grpc` (`port`, `dial_timeout_seconds`) by `templates/_helpers.tpl`.
- StatefulSet exposes the port as a named `grpc` container port; `service-headless` exposes it as a named service port so peers can dial each other.
- Both port additions are guarded by `if .Values.bifrost.cluster.grpc` so values overrides that omit the block render cleanly.

- Added `description` and `default` fields to numerous properties that previously had neither, including `initialPoolSize`, `disableDbPingsInHealth`, `logRetentionDays`, `asyncJobResultTTL`, `mcpAgentDepth`, `mcpToolExecutionTimeout`, `hideDeletedVirtualKeysInFilters`, `mcpDisableAutoToolInject`, and MCP `toolManagerConfig` fields
- Added `additionalProperties: false` to multiple objects (`bifrost.config`, `bifrost.pricing`, `proxyConfig`, `concurrencyConfig`, `providerConfig`, `credentialsSecret`, and auth provider configs) to reject unknown keys at validation time
- Added three new `bifrost.client` fields:
- `allowPerRequestContentStorageOverride` — controls whether per-request headers can override content logging behavior
- `allowPerRequestRawOverride` — controls whether per-request headers can override raw provider request/response passthrough
- `mcpExternalBaseUrl` — public base URL for OAuth callbacks and discovery metadata behind a reverse proxy, supporting both string and env-var object forms
- Added two new `bifrost.cluster.discovery` fields:
- `bindPort` — port to bind for cluster communication
- `dialTimeout` — timeout for discovery dial operations as a Go duration string
- Changed `allowedOrigins` items from `oneOf` to `anyOf` and removed the redundant `not: { const: "*" }` constraint on the URI branch
- Tightened the env-var pattern to require a valid identifier start character (`[A-Za-z_]`) for proxyConfig.url
- Expanded `toolSyncInterval` to accept either a Go duration string (with a stricter regex) or a legacy integer (nanoseconds) for backward compatibility.
- Marked `enforceGovernanceHeader` as deprecated in its description
- Added `mdnsService` description for local network discovery

## Changelog

- Surfaced `bifrost.client.enforceAuthOnInference` in `values.yaml` as a commented default with usage notes. The field was already wired in `_helpers.tpl` to render to `client.enforce_auth_on_inference` and declared in `values.schema.json`; this change makes the knob discoverable without altering default rendered config.
- Marked `bifrost.client.enforceGovernanceHeader` as deprecated in `values.yaml` (use `enforceAuthOnInference` instead). Schema description was already deprecated in 2.1.11.
