### Honcho API and SDK Changelogs
<Tabs>
    <Tab title="Honcho API">
        <Update label="v3.0.4 (Current)">
        ### Added

        - JSONB metadata validation enforces 100 key limit and max depth of 5 (#419)

        ### Changed

        - Schemas refactored from single `schemas.py` into `schemas/api.py`, `schemas/configuration.py`, and `schemas/internal.py` with backwards-compatible re-exports (#419)

        ### Fixed

        - Missing `deleted_at` filter on `RepresentationManager._query_documents_recent()` and `._query_documents_most_derived()` allowed soft-deleted documents to leak into the deriver's working representation (#456)
        - `CleanupStaleItemsCompletedEvent` emitted spuriously when no queue item was actually deleted (#454)
        - Empty JSON file uploads caused unhandled errors; now returns normalized error responses (#434)
        - Memory leak: `_observation_locks` switched to `WeakValueDictionary` to prevent unbounded growth (#419)
        - SQL injection in `dependencies.py`: parameterized `set_config` calls to prevent injection via request context (#419)
        - NUL byte crashes: string inputs (message content, queries, peer cards) now stripped at schema level (#419)
        - Filter recursion depth capped at 5 to prevent stack overflow (#419)
        - Dedup-skipped observations now correctly reflected in created counts (#477)
        - External vector store support for message search — routes queries through configured external vector store with oversampling and
          deduplication to handle chunked embeddings (#479)
        - Dialectic agent no longer holds a DB connection during LLM calls — embeddings are pre-computed before tool execution, DB sessions isolated in `extract_preferences`, `query_documents` no longer accepts a DB session parameter (#477)
        </Update>
        <Update label="v3.0.3">
        ### Added

        - Consolidated session context into a single DB session with 40/60 token budget allocation between summary and messages
        - Observation validation via `ObservationInput` Pydantic schema with partial-success support and batch embedding with per-observation fallback
        - Peer card hard cap of 40 facts with case-insensitive deduplication and whitespace normalization
        - Safe integer coercion (`_safe_int`) for all LLM tool inputs to handle non-integer values like `"Infinity"`
        - Embedding pre-computation and reuse across multiple search calls in dialectic and representation flows
        - Peer existence validation in dialectic chat endpoints — raises ResourceNotFoundException instead of silently failing
        - Logging filter to suppress noisy `GET /metrics` access logs
        - Oolong long-context aggregation benchmark (synth and real variants, 1K–4M token context windows)
        - MolecularBench fact quality evaluation (ambiguity, decontextuality, minimality scoring)
        - CoverageBench information recall evaluation (gold fact extraction, coverage matching, QA verification)
        - LoCoMo summary-as-context baseline evaluation
        - Webhook delivery tests, dependency lifecycle tests, queue cleanup tests, summarizer fallback tests
        - Parallel test execution via pytest-xdist with worker-specific databases
        - `test_reasoning_levels.py` script for LOCOM dataset testing across reasoning levels

        ### Changed

        - Workspace deletion is now async — returns 202 Accepted, validates no active sessions (409 Conflict), cascade-deletes in background
        - Redis caching layer now stores plain-dict instead of ORM objects, with v2-prefixed keys, storage, resilient `safe_cache_set`/`safe_cache_delete` helpers, and deferred post-commit cache invalidation
        - All `get_or_create_*` CRUD operations now use savepoints (`db.begin_nested()`) instead of commit/rollback for race condition prevention
        - Reconciler vector sync uses direct ORM mutation instead of batch parameterized UPDATE statements
        - Summarizer enforces hard word limit in prompt and creates fallback text for empty summaries with `summary_tokens = 0`
        - Blocked Gemini responses (SAFETY, RECITATION, PROHIBITED_CONTENT, BLOCKLIST) now raise `LLMError` to trigger retry/backup-provider logic
        - Gemini client explicitly sets `max_output_tokens` from `max_tokens` parameter
        - All deriver and metrics collector logging replaced with structured `logging.getLogger(__name__)` calls
        - Dreamer specialist prompts updated to enforce durable-facts-only peer cards with max 40 entries and deduplication
        - `GetOrCreateResult` changed from `NamedTuple` to `dataclass` with `async post_commit()` method
        - FastAPI upgraded from 0.111.0 to 0.131.0; added pyarrow dependency
        - Queue status filtering to only show user-facing tasks (representation, summary, dream); excludes internal infrastructure tasks

        ### Fixed

        - JWT timestamp bug — `JWTParams.t` was evaluated once at class definition time instead of per-instance
        - Session cache invalidation on deletion was missing
        - `get_peer_card()` now properly propagates `ResourceNotFoundException` instead of swallowing it
        - `set_peer_card()` ensures peer exists via `get_or_create_peers()` before updating
        - Backup provider failover with proper tool input type safety
        - Removed `setup_admin_jwt()` from server startup

    <Tab title="Python SDK">
        [Python SDK](https://pypi.org/project/honcho-ai/)
        <Update label="v2.1.0">
        ### Added

        - `created_at` property on `Peer` and `Session` objects
        - `is_active` property on `Session` objects
        - `get_message(message_id)` method on `Session` (sync and async) to fetch a single message by ID
        - `page`, `size`, and `reverse` pagination parameters on all list methods

        ### Changed

        - **Breaking**: `peer()` and `session()` now always make a get-or-create API call — no more lazy initialization
        - Response configuration models now tolerate unknown fields from newer servers for forward compatibility

        ### Fixed

        - Sync and async `Session.get_metadata()`, `get_configuration()`, and `refresh()` now refresh cached `created_at` and `is_active` values along with metadata and configuration

    <Tab title="TypeScript SDK">
        [TypeScript SDK](https://www.npmjs.com/package/@honcho-ai/sdk)
        <Update label="v2.1.0">
        ### Added

        - `createdAt` property on `Peer` and `Session` wrapper objects
        - `isActive` property on `Session` wrapper objects
        - `getMessage(messageId)` method on `Session` to fetch a single message by ID
        - `Peer.representation()`, `Session.representation()`, and `Session.context()` now accept `Message` objects for `searchQuery`
        - `page`, `size`, and `reverse` pagination controls on all list methods

        ### Changed

        - **Breaking**: `searchQuery` removed from top-level `context()` options — use `representationOptions.searchQuery` instead:
          ```typescript
          // Before (v2.0.x)
          await session.context({ searchQuery: "..." });
          // After (v2.1.0)
          await session.context({ representationOptions: { searchQuery: "..." } });
          ```
        - List methods (`peers()`, `sessions()`, `messages()`, `workspaces()`) support both the new options object and the legacy raw-filter form
        - Representation search options now accept strings and content-like objects, including `Message` instances, while rejecting whitespace-only or invalid runtime inputs
        - **Breaking**: `peer()` and `session()` now always make a get-or-create API call — no more lazy initialization. If you relied on constructing SDK objects without triggering a network request, note that every `peer()` and `session()` call now hits the API:
          ```typescript
          // Before (v2.0.x) — no API call
          const session = honcho.session("my-session");
          // After (v2.1.0) — makes a get-or-create API call
          const session = await honcho.session("my-session");
          ```
        - Response configuration models now tolerate unknown fields from newer servers for forward compatibility
        - Moved `@types/node` from `dependencies` to `devDependencies`

        ### Fixed

        - `uploadFile()` now rejects unsupported top-level binary/object inputs and only validates inputs the serializer can actually upload
        - `uploadFile()` now serializes message configuration using API field names, matching `addMessages()`
        - Session fetch methods now refresh cached `createdAt` and `isActive` values alongside metadata and configuration
        </Update>
        <Update label="v2.0.2">
        ### Changed

        - Client constructor now rejects unknown options via `.strict()` Zod validation. Previously, misspelled options (e.g., `baseUrl` instead of `baseURL`) were silently ignored, causing the SDK to fall back to defaults. Now a `ZodError` is thrown with the unrecognized key name.
        - All input schemas now use `.strict()` validation to reject unknown fields.
        - `FileUploadSchema.configuration` now uses `MessageConfigurationSchema` instead of open record type.

        ### Fixed

        - README example used `baseUrl` instead of `baseURL`.
        </Update>
        <Update label="v2.0.1">
        ### Added

        - `setPeerCard` method

        ### Changed

        ### Added
