* fix(deps): address critical and high severity security vulnerabilities
Bump vulnerable dependencies to patched versions across the monorepo:
Python (critical/high):
- fastmcp >=2.14.0 → >=3.2.0 (SSRF, path traversal, OAuth confused deputy, command injection)
- langchain-core >=1.2.11 → >=1.2.22 (path traversal in legacy load_prompt)
Python (low):
- cryptography >=46.0.5 → >=46.0.6 (incomplete DNS name constraint enforcement)
- pygments: add >=2.20.0 pin (ReDoS via GUID regex)
Node.js:
- serialize-javascript ^7.0.3 → ^7.0.5 (CPU exhaustion DoS)
- handlebars: add >=4.7.9 override (JS injection via AST type confusion)
- path-to-regexp: add >=0.1.13 override (ReDoS via route params)
- brace-expansion: add version range override (process hang/memory exhaustion)
Also adds type: ignore comments for FastMCP 2.x private attribute access that
ty now flags since FastMCP 3.x removed _tool_manager (guarded by try/except
and hasattr at runtime).
Regenerated all lock files across API, integrations, and tests.
* fix(deps): add ajv v8 scoped overrides for schema-utils and ajv-keywords
The global ajv ^6.14.0 override caused schema-utils and ajv-keywords to
receive ajv v6, but they require ajv v8 (for dist/compile/codegen). Add
scoped overrides to ensure these packages get ajv v8 while the global
override remains for packages that need v6.
* fix(tests): remove stateless_http from FastMCP() constructor calls
FastMCP 3.x no longer accepts stateless_http in the constructor. The
tests call tools directly without HTTP transport, so the parameter is
not needed.
* fix: update MCP tests for FastMCP 3.x _tool_manager removal
FastMCP 3.x removed _tool_manager. Tests now use
_local_provider._components for sync tool dict access and
mcp.list_tools() for async filtered tool listing.
* fix: resolve docusaurus build failures (ajv overrides + missing blog date)
- Remove global ajv ^6.14.0 override and scoped ajv-keywords/schema-utils
overrides that caused webpack compilation errors manifesting as
"Cannot read properties of undefined (reading 'date')" during SSR
and "these parameters are deprecated" warnings. Natural version
resolution (v6.12.6+ for v6 consumers, v8+ for v8 consumers) already
satisfies the security fix (>= 6.12.3).
- Add missing date frontmatter to learning-capabilities blog post.
* chore: regenerate openapi spec and docs skill
* feat: add audit log for feature usage tracking
Add full auditability for all mutating and core API operations across
HTTP, MCP, and system (worker) transports. Audit entries record raw
request/response as JSONB, timing (started_at/ended_at), action, and
transport type.
Backend:
- New audit_log table with JSONB columns for expandability without
future migrations (merge migration of 3 existing heads)
- AuditLogger with fire-and-forget writes via asyncio.create_task
- @audited decorator on 28 HTTP route handlers
- MCP tool audit wrapping for 16 auditable tools
- Worker task execution wrapped with audit_context
- List endpoint with action, transport, date range filters + pagination
- Stats endpoint with per-day counts for charting
- Configurable retention sweep (concurrent-safe DELETE)
Config (env-only, static):
- HINDSIGHT_API_AUDIT_LOG_ENABLED (default: false)
- HINDSIGHT_API_AUDIT_LOG_ACTIONS (comma-separated allowlist, empty=all)
- HINDSIGHT_API_AUDIT_LOG_RETENTION_DAYS (default: -1, keep forever)
Control Plane:
- New "Audit Logs" tab on bank configuration page
- Line chart showing request volume (today/7d/30d) with action filter
- Filterable table with action, transport, date range filters
- Paginated list with detail dialog showing raw request/response JSON
Tests:
- 13 tests covering list, filters, pagination, stats, disabled mode,
action allowlist, and ordering
* fix: split 3-way merge migration into two 2-way merges
Alembic doesn't support 3-parent merge migrations. Split into a no-op
merge of 2 heads (b1c2d3e4f5g6) followed by the audit_log table
migration merging the third head.
* fix: correct merge migration to merge actual 2 heads
The original analysis incorrectly identified 3 heads. There were only 2
(a3b4c5d6e7f8 and c8e5f2a3b4d1). Remove the unnecessary intermediate
merge migration and fix the audit_log migration to merge these 2 heads.
* fix: use 'heads' instead of 'head' in migration runner
Alembic's upgrade('head') fails when multiple heads exist (e.g. from
namespace package overlaps between hindsight-api and hindsight-api-slim).
Using 'heads' (plural) handles this gracefully by upgrading all branches.
* chore: regenerate OpenAPI spec with audit log endpoints
* chore: regenerate TypeScript client and docs skill OpenAPI spec
Python and Go clients still need regeneration (requires Docker).
* chore: regenerate all client SDKs (Python, Go, TypeScript)
Adds generated audit log API clients for Python (audit_api.py),
Go (api_audit.go), and TypeScript client type updates.
* feat: independent versioning for integrations
- Add per-integration changelog pages at /changelog/integrations/<name>
- Move main changelog to changelog/index.md (URL unchanged)
- Add --integration flag to generate-changelog for LLM-based per-integration changelog generation
- Add scripts/release-integration.sh <name> <version> for cutting integration releases
- Add .github/workflows/release-integration.yml to publish on integrations/** tags
- Remove integrations from main release.sh and release.yml cycle
* fix: add agno and hermes integration docs to version-0.4 for production build
* chore: apply ruff formatting to generate_changelog.py
* feat: add 4-tab code parity across all documentation examples
Every code snippet Tabs block now has Python, Node.js, CLI, and Go variants.
Raw HTTP/curl tabs replaced with proper SDK calls.
New example files:
- Go: retain.go, recall.go, reflect.go, memory-banks.go, directives.go,
mental-models.go, documents.go, main-methods.go
- Shell: memory-banks.sh, directives.sh, mental-models.sh
- Node.js: mental-models.mjs
Extended example files with missing sections:
- recall.mjs/sh: world/experience/observation types, token-budget, all tag modes
- reflect.sh: reflect-with-params, reflect-disposition, reflect-sources, reflect-with-tags
- reflect.mjs: reflect-with-tags, fixed reflect-sources API usage
- retain.mjs/sh: retain-conversation, retain-batch, retain-files-batch
SDK/CLI additions:
- TypeScript: getMentalModelHistory method
- CLI recall: --tags, --tags-match flags
- CLI reflect: --tags, --tags-match, --include-facts flags
- CLI directive update: --is-active flag
- CLI bank set-config: --retain-mission, --retain-extraction-mode,
--observations-mission, --reflect-mission, --disposition-* flags
Build validation:
- scripts/check-code-parity.mjs validates 4-tab parity across all MDX files
- Integrated into npm run build — fails if any Tabs block is missing a variant
* fix: fix doc examples for Go, Node.js, CLI + add mental model with-id examples
- Fix Go Budget constants: BUDGET_HIGH/LOW/MID → HIGH/LOW/MID
- Fix Go documents.go: ListDocuments returns []map[string]interface{}, use map access
- Fix Go retain.go: use correct relative path for sample.pdf
- Fix Node.js createMentalModel: use positional args (name, sourceQuery) not object
- Add CLI 'history' subcommand for mental models (api.rs, main.rs, mental_model.rs)
- Rebuild TypeScript/Python clients to support id param in createMentalModel
- Add create-mental-model-with-id examples across all 4 languages and docs
* fix: move id param to end of create_mental_model signature for backwards compat
* feat(typescript-client): add Deno compatibility
- Switch build from tsc to tsup for dual CJS + ESM output with proper exports field
- Add deno_setup.ts preload that injects Jest-compatible globals (describe/test/expect) via @std/testing/bdd and @std/expect
- Fix generated client.gen.ts: exclude hey-api internal `client` field from RequestInit spread to avoid conflict with Deno.HttpClient
- Add test:deno npm script using --unstable-sloppy-imports and --preload
- Add test-typescript-client-deno CI job using denoland/setup-deno@v2 (v2.x)
- Update docs: rename page to TypeScript / JavaScript Client, add Deno installation section
* feat: add Deno compatibility to ai-sdk and chat integrations
- Switch ai-sdk and chat builds from tsc to tsup (ESM bundle, eliminates
extension-less import issues in Deno)
- Add deno.json import map to ai-sdk redirecting 'vitest' to a custom
vitest-compat.ts shim and bare npm specifiers to npm: URLs
- Add vitest-compat.ts shim implementing vi.fn()/vi.spyOn()/vi.mocked()
using @std/expect's Symbol.for("@MOCK") interface so toHaveBeenCalledWith
and other mock matchers work under Deno
- Add test:deno script to ai-sdk (all 30 tests pass under Deno)
* ci: add Deno test job for ai-sdk integration
Adds a new test-ai-sdk-integration-deno CI job that runs the ai-sdk
unit tests under Deno LTS, verifying Deno compatibility of the package.
* fix: remove broken link to non-existent n8n blog post in streamlit post
* fix: patch client.gen.ts for Deno compatibility during generation
Add a post-generation patch step to generate-clients.sh that removes
the hey-api internal 'client' field from the RequestInit spread in
client.gen.ts. Deno's Request constructor rejects 'client' because it
conflicts with the Deno.HttpClient option name.
* docs: revamp sidebar with icon grid components and language support
- Merge Clients and Integrations sections into the developer sidebar
(removed top-level SDKs navbar item)
- Reorder sidebar: Architecture → API → Clients → Integrations → Hosting
- Unify icon system using react-icons (LuXxx/SiXxx) via customProps.icon
- Add uppercase section titles with increased spacing and reduced indentation
- Rename Node.js → "JavaScript / TypeScript" with TypeScript icon
- Add reusable IconGrid and SupportedGrids components (ClientsGrid,
IntegrationsGrid, LLMProvidersGrid)
- Use grids in FAQ, Models, Overview, and Quick Start pages
- Convert developer/index.md, models.md, faq.md to MDX for JSX support
* fix: use inline style for label color to prevent link color inheritance
* fix: label visibility and rename JavaScript/TypeScript to TypeScript
* feat: add HTTP client to grid and OpenAI Compatible to LLM providers grid
* feat: support Batch API for retain (openai/groq)
* api
* stop batch api if sync
* fix(ui): improve toast notifications with brand colors and proper styling
- Replace all window.alert() calls with toast notifications
- Add interceptor-based error handling in API client
- Use different toast styles based on HTTP status codes (4xx = warning, 5xx = error)
- Apply Hindsight brand colors to toasts (primary blue for info, destructive red for errors, etc.)
- Remove obsolete error handling files (hindsight-client-with-toast.ts, api-error-handler.ts)
- Fix toast background conflicts by removing base bg-background class
* fix: restore retain_batch_tokens config that was accidentally removed during rebase
* feat: add comprehensive OpenTelemetry tracing
- Add tool execution spans for reflect operations
- Add tool call information (names, params) to spans
- Change verification scope from 'test' to 'verification'
- Add hindsight.reflect_generation span for done() processing
- Implement no-op tracer for improved code readability
- Update documentation for OTEL configuration
- Resolve merge conflicts from rebase
* fix: properly serialize Pydantic models in span recording
- Add _serialize_for_span() helper to handle Pydantic models
- Update all providers to use the helper function
- Fixes test failures with 'Object of type X is not JSON serializable'
* feat: add Grafana LGTM stack for unified local observability
Add Grafana LGTM (Loki, Grafana, Tempo, Mimir) as the recommended
local development observability stack. This provides traces, metrics,
and logs in a single Docker container instead of separate tools.
Changes:
- Add scripts/dev/grafana/ with docker-compose and README
- Add scripts/dev/start-grafana.sh startup script
- Update .env.example to reference Grafana LGTM
- Update configuration docs to emphasize Grafana LGTM as primary option
- Reorder OTLP backend list to show Grafana LGTM first
Benefits:
- Single container vs multiple separate tools (Jaeger, SigNoz, etc.)
- ~515MB image with full observability stack
- Compatible with existing OTLP configuration
- Simpler local development setup
* chore: remove SigNoz scripts and references
Remove SigNoz observability stack in favor of Grafana LGTM as the
sole recommended local development tracing solution.
Changes:
- Delete scripts/dev/signoz/ directory and all SigNoz configurations
- Delete scripts/dev/start-signoz.sh startup script
- Remove SigNoz references from .env.example
- Remove SigNoz from OTLP backends list in configuration docs
Grafana LGTM provides the same capabilities (traces, metrics, logs)
in a simpler single-container setup.
* feat: add consolidation span hierarchy for tracing
Add parent-child span structure for consolidation operations:
- hindsight.consolidation: Parent span for each memory being processed
- hindsight.consolidation_recall: Child span for finding related observations
- LLM call span: Automatically created by LLM provider (scope="consolidation")
This enables detailed timing breakdown in Grafana Tempo:
- Total consolidation time per memory
- Time spent in recall
- Time spent in LLM call
- Time spent executing actions (create/update)
All consolidation tests pass (31/31).
* feat: add Prometheus metrics and GenAI dashboard to Grafana stack
Add comprehensive metrics and dashboarding to the Grafana LGTM stack:
Metrics Collection:
- Configure Prometheus to scrape Hindsight API /metrics endpoint
- Scrape interval: 10 seconds
- Targets hindsight-api on host.docker.internal:8888
GenAI Dashboard:
- Pre-configured dashboard with 6 panels:
- LLM call rate (by provider/model)
- LLM call duration (p50/p95 by scope)
- Token usage - input tokens/sec by scope
- Token usage - output tokens/sec by scope
- Operations rate (retain/recall/reflect/consolidation)
- Operation duration p95 by operation type
Configuration:
- Mount prometheus.yml for metrics scraping
- Mount dashboards directory for auto-provisioning
- Add host.docker.internal mapping for container->host access
- Dashboard provisioning with auto-reload every 10s
Documentation:
- Updated README with metrics viewing instructions
- Added PromQL query examples
- Documented dashboard access and navigation
This provides full observability: traces (Tempo) + metrics (Prometheus/Mimir) + dashboards (Grafana)
* refactor: merge Grafana setup into existing monitoring stack
Consolidate the separate scripts/dev/grafana/ setup into the existing
scripts/dev/monitoring/ stack, using Grafana LGTM (Loki, Grafana, Tempo, Mimir).
Changes:
- Remove separate scripts/dev/grafana/ directory and start-grafana.sh
- Rewrite scripts/dev/monitoring/start.sh to use Docker + Grafana LGTM
(was: download native Prometheus/Grafana binaries)
- Add docker-compose.yaml for Grafana LGTM container
- Add prometheus.yml for scraping Hindsight API metrics
- Mount existing dashboards from monitoring/grafana/dashboards/
- Add comprehensive README.md
Benefits:
- Single unified monitoring command: ./scripts/dev/start-monitoring.sh
- Uses existing dashboard files (hindsight-operations, hindsight-llm, hindsight-api-service)
- Simpler setup: Docker-based vs downloading/running native binaries
- Full observability: traces + metrics + logs + dashboards in one container
- Standard ports: Grafana on 3000, OTLP on 4317/4318
Architecture:
- Grafana LGTM container (~515MB) provides all components
- Dashboards auto-provisioned from monitoring/grafana/dashboards/
- Prometheus scrapes host.docker.internal:8888/metrics
- Shared hindsight-network for future service-to-service tracing
* fix: run monitoring stack in foreground for easy Ctrl+C stop
Change docker-compose from detached (-d) to foreground mode.
Users can now stop the stack with Ctrl+C instead of needing
to run docker-compose down separately.
* fix: remove invalid home dashboard path and obsolete version field
- Remove GF_DASHBOARDS_DEFAULT_HOME_DASHBOARD_PATH environment variable
(was pointing to wrong path causing 'Failed to load home dashboard' error)
- Remove obsolete 'version' field from docker-compose.yaml
(docker-compose v2+ doesn't require version field)
* fix: load Hindsight dashboards in Grafana LGTM
Mount Hindsight dashboard JSON files and custom provisioning config
to make dashboards visible in Grafana.
Changes:
- Mount hindsight-operations.json, hindsight-llm.json, hindsight-api-service.json to /otel-lgtm/
- Create grafana-dashboards.yaml with all dashboard providers (default + Hindsight)
- Mount custom provisioning config to override LGTM default
All 3 Hindsight dashboards now appear in Grafana UI with metrics
from Prometheus scraping the Hindsight API /metrics endpoint.
* fix: configure Prometheus to scrape Hindsight API metrics
Update prometheus.yml to include both OTLP receiver config (from LGTM)
and scrape_configs for pulling metrics from Hindsight API.
Changes:
- Mount prometheus.yml to /otel-lgtm/prometheus.yaml (where LGTM reads it)
- Add scrape_configs section to pull from host.docker.internal:8888/metrics
- Keep OTLP receiver configuration for trace metrics
- Set scrape_interval to 5s
Verified: Prometheus now successfully scrapes hindsight_llm_calls_total
and other Hindsight metrics. Dashboards now show live data!
* feat: add comprehensive tracing for recall and improve reflect/mental_model_refresh spans
- Add recall operation tracing with parent-child span hierarchy
- Parent: hindsight.recall with attributes (bank_id, query, fact_types, etc.)
- Children: recall_embedding, recall_retrieval, recall_fusion, recall_rerank
- Fixed context propagation using start_as_current_span()
- Improve reflect tracing spans
- Remove reflect_generation spans, use reflect instead
- Change done() tool processing to hindsight.reflect_tool_call
- Fix mental_model_refresh span nesting
- Add _skip_span parameter to reflect_async to avoid duplicate hindsight.reflect spans
- Mental model refresh now has clean span hierarchy without nested reflect parent
- Add comprehensive tracing verification tests
- Test span hierarchy and attributes for all operations
- Verify parent-child relationships
- 5 passing tests covering recall, reflect, consolidation, and mental_model_refresh
* refactor: remove redundant is_tracing_enabled() checks
- Remove all is_tracing_enabled() conditional checks before tracing calls
- NoOpTracer/NoOpSpan handle disabled tracing automatically
- Simplify code by always calling tracer methods directly
- Fix NoOpTracer.start_as_current_span() to yield NoOpSpan instead of None
Changes:
- memory_engine.py: Remove 5 is_tracing_enabled checks in recall spans
- agent.py: Remove 2 is_tracing_enabled checks in reflect tool spans
- tracing.py: Fix NoOpTracer context manager to yield proper NoOpSpan
This eliminates ~50 lines of redundant conditional code while maintaining
identical behavior.
* docs: simplify distributed tracing section in monitoring.md
- Make tracing documentation more concise
- Focus on span hierarchy and attributes
- Remove verbose troubleshooting and performance sections
- Keep configuration.md for env vars only
* fix(sec): upgrade vulnerable deps
* feat: add comprehensive logging to upgrade tests
- Modify VersionRunner to write server logs to /tmp/upgrade-test-*.log files
- Add pytest hook to automatically dump server logs on test failure
- Add CI workflow step to show upgrade test logs (always runs)
- Improves debuggability when upgrade tests fail in CI
This addresses the issue where upgrade test failures in CI were
impossible to debug because API server logs were not visible.
* Improve graph visualization on the UI
* Fix double animation when loading the graph visualization
* Fix typescript issues
* CI test changes for temporal scenarios
* Fix typescript errors
* Fix animation issue on opinions and experiences
* Load operation validator extension in main entry point
Enable the operation validator extension to be loaded from environment
configuration and passed to MemoryEngine, allowing pre/post operation
hooks for usage metering, rate limiting, and audit logging.
* Fix reflect background task authentication and add internal flag
- Pass API key to background opinion storage task for proper auth
- Add internal flag to RequestContext for tracking internal operations
- Background opinion storage now authenticates correctly with tenant
* Add api_key_id to RequestContext for usage tracking
- Add api_key_id field to RequestContext to track which API key was used
- Enables per-API-key usage analytics in the metering system
* Fix HTTP error handling for authentication and validation errors
- Add status_code parameter to ValidationResult and OperationValidationError
- Convert OperationValidationError to HTTPException with proper status codes
- Fix authentication errors to return 401 instead of raising internal errors
- Re-raise HTTPException in exception handlers to prevent swallowing errors
* Fix AuthenticationError handling in memory engine
- Raise AuthenticationError from memory_engine._authenticate_tenant instead
of HTTPException so unit tests pass
- Add AuthenticationError handling in HTTP layer to convert to 401 responses
- Fixes failing TestMemoryEngineTenantAuth tests
* Add global exception handler for AuthenticationError
Returns proper 401 status code for all authentication failures
across all endpoints, not just the ones with explicit handlers.
* Simplify exception handling: use global AuthenticationError handler
- Remove redundant individual exception handlers
- Add 'except AuthenticationError: raise' before generic Exception handlers
to let global handler process auth errors uniformly
* Refactor background tasks to use tenant_id instead of api_key
This makes the core more generic - it passes tenant_id (which is
extension-agnostic) rather than api_key (which is cloud-specific).
- Add tenant_id field to RequestContext
- Pass tenant_id instead of api_key to background tasks
- Extensions can check internal=True with tenant_id to bypass normal auth
* Fix exception propagation: include HTTPException in re-raise
After cleanup of redundant exception handlers, 404 errors were
returning 500 because HTTPException was caught by the generic
except Exception handler. Fixed by combining AuthenticationError
and HTTPException in the re-raise pattern.
* Add documentation code validation system
- Create runnable example scripts in examples/api/ (19 files)
- Add CodeSnippet component for extracting marked sections
- Add raw-loader dependency for importing source files
- Create sample retain-new.mdx showing new approach

* Add documentation code validation CI job
- Use uv sync + uv run pattern (matches existing CI)
- Add requests to test dependencies for cleanup scripts
* Fix async API client usage in documents.py example

* Fix opinions.py: use actual API attributes instead of non-existent ones
* Fix example scripts: remove non-existent API attributes
- recall.py: remove .weight, fix entities iteration (dict not list)
- retain.mjs: remove result.async check
