framework/v1.7.0

## Framework Release v1.7.0

- feat: model allow and block lists accept `regex:` entries. The provider-key aggregate keeps an exact name next to a pattern that also covers it, the catalog allow check tries a pattern against the bare name and `provider/model`, and listings skip pattern entries
- fix: ClickHouse log store deletes no longer run as heavyweight `ALTER TABLE ... DELETE` mutations. The retention cleaner issued one such mutation per 100 rows, each rewriting the whole current-month part, and the once-a-minute stale-`processing` sweeps issued one per table unconditionally, filling replica disks in minutes. Every delete on the ClickHouse store (retention sweep, `Flush`/`FlushMCPToolLogs`, UI log deletes, async job and webhook delivery expiry) is now a single lightweight `DELETE FROM ... WHERE` per run, skipped entirely when nothing matches. The table TTL derived from `logs_store.retention_days` is now reconciled on every startup with `MODIFY TTL` (metadata only), so changing the value reaches existing tables; `0` leaves an existing TTL untouched (#7098)
- feat: access profiles and governance projects reference Virtual MCPs through `virtual_mcp_name`, so config files are portable across environments instead of carrying database-assigned integer IDs. Names resolve to stored records on startup and a name that matches nothing is refused; `virtual_mcp_id` is deprecated, still accepted, and wins when both are set. `mcp_configs` (`{ mcp_client_id, tools_to_execute }`) replaces the `mcp_servers` and `mcp_tool_overrides` include-exclude model with a single allowlist, where `["*"]` grants all tools including future ones, `[]` grants none, and a named list grants only those; the old keys are deprecated, still accepted, and folded into the new shape at load time (#7181)
- feat: `MCPToolLog` records governance entity names beside their IDs, so MCP tool logs carry the same attribution shape the `logs` table has instead of rendering raw UUIDs in the dashboard. `user_name`, `team_name`, `customer_name` and `business_unit_name` stop being `gorm:"-"` transients and become storage; the multi-valued `team_ids`/`team_names`, `customer_ids`/`customer_names` and `business_unit_ids`/`business_unit_names` sets are stored as index-aligned JSON arrays; and `budget_ids` and `rate_limit_ids` are recorded id-only, as in `logs`. Names are written from the request context at ingestion through the new `MCPToolLog.ApplyGovernance` in `framework/logstore/governance.go`, with nothing resolved on read. Added by migration `mcp_tool_logs_add_governance_snapshots` (#7154)
- feat: endpoint-attributed MCP observations are carried in the standard logging pipeline, so inspected MCP tool calls are logged with bounded identity (device, app key, server label, tool name, decision) sourced from the gateway rather than from payload-supplied headers. `SetMCPObservation` attaches the attribution to a `BifrostContext` and `applyMCPObservation` writes it onto the `MCPToolLog` from both `PreMCPHook` and `PostMCPHook`, snapshotting the observation so it cannot alias across async log entries (#6959)
- feat: the `error_type` classification vocabulary is threaded through the framework so `bifrost_error_requests_total` can carry a normalized fault-domain label alongside `status_code` (#7141)
- feat: model pricing supports time-of-day peak and off-peak rates. `TableModelPricing` gains `off_peak_cost_multiplier` (a nullable float) and `peak_hours` (a JSON-serialized `PeakHoursSchedule` of recurring weekly windows using IANA timezone names, weekday numbers and half-open `HH:MM` intervals that may wrap past midnight), added by migration `add_time_of_day_pricing_columns` and aliased into the datasheet package so the JSON shape stays self-contained. The cost engine evaluates the schedule against the request start time and scales usage-based charges by the multiplier when the request falls outside every peak window, applied once in `computeCostFromInput` so every modality is covered; flat `CostPerRequest` and `SearchQueriesCost` fees are excluded, as is `AdditionalCost`, which is discounted independently through its own pricing rows. Both fields are exposed on `PricingPatch` in the OpenAPI and governance schemas, with `off_peak_cost_multiplier` bounded to `(0, 1]` (#6574, #6575, #6576)
- feat: `SecretVar.RedactedIfSecret()` is used for non-credential fields in `ProviderConfig.Redacted()`, `Config.GetAllKeys()` and `Config.RedactMCPClientConfig()`, so regions, endpoints, service URLs and MCP connection strings surface as plaintext while anything env-var or vault-backed stays masked (#7085)
- feat: GA realtime transcription sessions are routed, governed, logged and priced through the normal framework pipeline, resolving the routing model from the nested `audio.input.transcription.model` that arrives in `session.update` rather than from the connect URL (#7089)
- feat: a `use_openai_endpoints` column on the provider keys table, added by migration `add_use_openai_endpoints_column`, opts a Bedrock key or alias into Bedrock's OpenAI-compatible endpoints instead of Converse (#7073)
- feat: the reserved tool-namespace list a provider keeps for its own server tools is read from the datasheet row `reserved_tool_namespaces`, so a namespace collision check no longer requires a code change (#7084)
- fix: `exchangeRefreshToken` includes `client_secret` only when the secret is non-empty, matching `exchangeCodeForTokensWithPKCE`. Public OAuth2 clients registered against servers that support only `token_endpoint_auth_method: none` have no secret, and unconditionally setting `client_secret=` sent an empty `client_secret_post` attempt that strict authorization servers answered with `invalid_client`, flipping the token row to `needs_reauth` even though the refresh token was valid (#7042)
- fix: the virtual key `allowed_models: ["*"]` handling for governance added in #6767 is reverted, returning the wildcard-with-empty-synced-catalog case to its previous behaviour (#7053)
