 ### Added
 
-- **Multi-source mode:** configure multiple Pinecone API keys / indexes in one MCP server via `PINECONE_SOURCES`, `--sources`, or a JSON config file (`PINECONE_CONFIG_FILE` / `--config-file`). New `list_sources` tool (when more than one source is configured). Optional `source` parameter on discovery and query tools; `list_namespaces` aggregates across sources and tags each namespace with `source`. See [CONFIGURATION.md](docs/CONFIGURATION.md#multi-source-mode), [TOOLS.md](docs/TOOLS.md#multi-source-mode), and deployment profiles in [CONFIGURATION.md](docs/CONFIGURATION.md#deployment-profiles).

 ### Changed
 
-- **Library:** `resolveConfig()` returns `CoreServerConfig`; `resolveAllianceConfig()` returns `AllianceServerConfig`. `setupCoreServer` / `setupAllianceServer` accept only their respective branded config and context types (`CoreServerContext` / `AllianceServerContext`). `ServerConfig` remains an alias for `ServerConfigBase` on read paths (`ctx.getConfig()`). See [MIGRATION.md](docs/MIGRATION.md#unreleased-branded-serverconfig-types).

See [MIGRATION.md § 0.4.0 branded ServerConfig](docs/MIGRATION.md#040-branded-serverconfig-types).
+- **Library (internal):** Query and `keyword_search` response Zod schemas consolidated to a single canonical schema per type; permissive variants are derived via `.partial()` (no MCP payload shape change). See comment in `src/core/server/response-schemas.ts`.

+Version **0.4.0** adds **multi-source mode** (`PINECONE_SOURCES`, `list_sources`, optional `source` on query tools) and **breaking (types)** branded `CoreServerConfig` / `AllianceServerConfig` — `setupCoreServer` and `setupAllianceServer` now accept only matching config/context types.

 ## Upgrading to 0.3.0
 
-Version **0.3.0** includes breaking MCP and library changes: experimental response fields nested under `experimental`, branded `CoreServerConfig` / `AllianceServerConfig`, legacy module-facade deprecations, and core `resolveConfig` requiring an index name with suggest-flow off by default.

 When `PINECONE_SOURCES` or a config file is active, legacy module facades (`getNamespacesWithCache`, `registerUrlGenerator`, `markSuggested`, `requireSuggested`, etc.) operate on the **default source only** (first inline source, or `defaultSource` from JSON). They do not aggregate across projects. Prefer an explicit `ServerContext` built with `sourceRegistry` from `buildSourceRegistry()` for multi-tenant or multi-project embedding.
