* chore: remove dead code
* chore: remove extract_opinions from test and regenerate openapi
- Remove extract_opinions parameter from test_fact_extraction_analysis
- Regenerate OpenAPI spec after removing entity observations code
* chore: update generated files and apply formatting
- Regenerate Python and TypeScript client SDKs after main merge
- Apply ruff formatting to llm_wrapper.py
* fix: accept and filter deprecated 'opinion' fact type in recall
The dead code removal eliminated support for the 'opinion' fact type,
but existing clients may still pass it. Instead of rejecting it with
a ValueError, silently filter it out before validation to maintain
backward compatibility.
* feat(mcp): add Bearer token authentication support
Add HINDSIGHT_API_MCP_AUTH_TOKEN environment variable to enable
authentication for MCP endpoint. When set, all requests must include
a valid Authorization header (Bearer token or direct token).
If not set, MCP endpoint remains open for backwards compatibility
with local development environments.
* fix: propagate Bearer token from MCP middleware to tools for tenant auth
MCP tools were creating RequestContext() without api_key, causing
"Invalid API key" errors when tenant extension validates requests.
Now the Bearer token is extracted in middleware, stored in a context
variable, and passed through to all MCP tool RequestContext instances.
Replace the OpenAI-compatible endpoint approach with the native
google-genai SDK for Vertex AI. This eliminates the custom token
refresher, TokenInjectingTransport, and async lifecycle complexity
while also removing the 8192 output token cap that the OpenAI
endpoint enforced.
Changes:
- vertexai provider now uses genai.Client(vertexai=True) instead of
AsyncOpenAI with token-injecting transport
- Routes through existing _call_gemini/_call_with_tools_gemini paths
- Strips google/ prefix from model names (native SDK uses bare names)
- Preserves service account key auth via credentials parameter
- Delete vertexai_token_refresher.py (no longer needed)
- Strip markdown code fences in consolidator JSON parsing
- Rewrite vertexai tests for native SDK integration
* feat: support vertex as llm provider

* fix: add uv index-strategy to resolve dependency conflicts with pytorch index
When using pytorch index for faster torch downloads in CI,
filelock dependency resolution was failing because pytorch index
only has older versions. Adding unsafe-best-match strategy allows
uv to search all configured indexes.
Also fix type checking warnings from ty.
* fix: add index-strategy to root pyproject.toml for workspace-level uv resolution
* chore: regenerate client SDKs after Vertex AI support
* fix: include correct __version__ in python packages
* fix(embed): force CPU mode for local models in daemon to prevent XPC crashes
Adds HINDSIGHT_API_EMBEDDINGS_LOCAL_FORCE_CPU and HINDSIGHT_API_RERANKER_LOCAL_FORCE_CPU
environment variables to force CPU-only operation for local sentence-transformer models.
This prevents XPC_ERROR_CONNECTION_INVALID crashes on macOS when running in daemon mode.
The issue occurs because PyTorch's MPS (Metal Performance Shaders) backend has unstable
XPC connections in background processes, leading to C++ assertion failures that Python
exception handlers cannot catch.
Changes:
- config.py: Add ENV_*_FORCE_CPU constants and config dataclass fields
- embeddings.py: Add force_cpu parameter to LocalSTEmbeddings constructor
- cross_encoder.py: Add force_cpu parameter to LocalSTCrossEncoder constructor
- main.py: Set force CPU env vars in daemon mode, add fields to config constructor
The daemon mode automatically enables force CPU for both embeddings and reranker,
while normal mode allows hardware acceleration (GPU/MPS) as before.

* fix: add defensive error handling to PyTorch device detection
Wraps all PyTorch device detection code (torch.cuda.is_available()
and torch.backends.mps.is_available()) in try-except blocks that
gracefully fall back to CPU if any errors occur.
This complements PR #218's force_cpu configuration by ensuring the
code works reliably in all environments without configuration:
- CI environments with CPU-only PyTorch builds
- Systems without proper GPU/MPS support
- Partial or misconfigured PyTorch installations
The defensive approach prevents startup failures while still taking
advantage of GPU/MPS acceleration when available and force_cpu is
not explicitly set.
Changes:
- embeddings.py: Added try-except in initialize() and _reinitialize_model_sync()
- cross_encoder.py: Added try-except in initialize() and _reinitialize_model_sync()
* refactor: use get_config() for embeddings and reranker force_cpu
Changes create_embeddings_from_env() and create_cross_encoder_from_env()
to read configuration via get_config() instead of directly accessing
os.environ. This ensures consistency across the codebase and properly
respects the force_cpu configuration set by daemon mode.
Changes:
- embeddings.py: Use config.embeddings_local_model and config.embeddings_local_force_cpu
- cross_encoder.py: Use config.reranker_local_model and config.reranker_local_force_cpu
- Both: Use get_config() for provider, tei_url, and other config fields
- Note: Some fields not in config (like max_concurrent for local reranker) still read from os.environ
This fixes the issue where force_cpu was read inconsistently from environment
variables instead of using the centralized config system.
* test: clear config cache in test_create_from_env
Fixes test failure caused by cached config not picking up
environment variable changes in test. The test now calls
clear_config_cache() before and after patching os.environ
to ensure the factory function reads the test's env vars.
* refactor: add reranker_local_max_concurrent to config system
Adds reranker_local_max_concurrent to HindsightConfig dataclass
and removes the workaround in create_cross_encoder_from_env() that
was reading it directly from os.environ.
Changes:
- config.py: Add reranker_local_max_concurrent field to dataclass and from_env()
- main.py: Add reranker_local_max_concurrent to manual config constructor
- cross_encoder.py: Use config.reranker_local_max_concurrent instead of os.environ
This completes the refactoring to use the centralized config system
for all reranker configuration.

* chore: cleanup benchmarks runner with old flags
* fix tests
* fix: observations rely on source_memory_ids, no link copying
Observations no longer copy any memory_links from their source facts.
Instead, retrieval uses source_memory_ids to traverse:
- Entity connections: observation → source_memory_ids → unit_entities
- Semantic similarity: observations have their own embeddings
- Temporal proximity: observations have their own temporal fields
This avoids data duplication and fixes bidirectionality issues with
entity links being copied to observations.

* fix: prevent meta tensor issues when accelerate is installed without GPU
When accelerate is installed but no GPU is available, transformers can
incorrectly use lazy loading (meta tensors) which fails when
sentence-transformers tries to move the model to a device.
The fix checks hardware and installed packages to determine the right
loading strategy:
- GPU available: device=None, device_map=None (auto-detect GPU)
- No GPU + accelerate: device='cpu', device_map='cpu' (force CPU loading)
- No GPU + no accelerate: device='cpu', device_map=None (normal CPU)

* fix: add filelock for model initialization in parallel tests
When pytest-xdist runs multiple workers in parallel, they all try to
load models from the HuggingFace cache simultaneously, causing race
conditions and intermittent meta tensor errors.
Added filelock around embeddings and cross_encoder initialization in
conftest.py, similar to how pg0 database setup is serialized. Models
are now pre-initialized in the fixture before being passed to tests.

* fix: add MPS support for macOS Apple Silicon
Extend GPU detection to include Apple MPS backend in addition to CUDA.
This ensures macOS users with Apple Silicon use MPS acceleration
instead of being incorrectly routed to the CPU fallback path.
* Fix: Load extensions in server.py for multi-worker deployments
When running with multiple workers (--workers 2), uvicorn uses
`hindsight_api.server:app` import string instead of passing an app
object. The server.py module was not loading tenant/operation validator
extensions, causing authentication bypass in production.
This fix:
- Adds extension loading to server.py matching main.py behavior
- Sets extension context on tenant extension for schema provisioning
- Adds comprehensive unit tests for server.py extension loading
The tests specifically verify:
- TENANT extension is loaded when HINDSIGHT_API_TENANT_EXTENSION is set
- OPERATION_VALIDATOR is loaded when configured
- Extensions are passed to MemoryEngine constructor
- Extension context is set on tenant extension
- Server works correctly without extensions configured
* Add unit tests for main.py extension loading (single-worker path)
* fix: misc perf improvements

* feat: Record LLM token metrics via Prometheus
Wire up the existing token metrics infrastructure to actually record
token usage from LLM calls. The MetricsCollector already had
record_tokens() method and Prometheus counters (hindsight.tokens.input,
hindsight.tokens.output), but they were never being populated.
Changes:
- Import get_metrics_collector in llm_wrapper.py
- Call record_tokens() after successful LLM calls for:
- OpenAI/Groq (using response.usage.prompt_tokens, completion_tokens)
- Anthropic (using response.usage.input_tokens, output_tokens)
- Gemini (using response.usage_metadata.prompt_token_count, candidates_token_count)
- Add test file to verify token metrics are recorded
Note: Ollama's native API doesn't return token usage, so metrics
are not recorded for that provider.
The token metrics will now be available via /metrics endpoint:
- hindsight_tokens_input_total
- hindsight_tokens_output_total
* feat: add per-request token usage tracking to retain and reflect endpoints
- Add TokenUsage model with input_tokens, output_tokens, total_tokens
- Return usage metrics in retain response (sync operations only)
- Return usage metrics in reflect response
- Update Python, TypeScript, and Rust clients
- Add API documentation for usage fields
- Add changelog entry
