* doc: update cookbook
* fix(cookbook): preserve tag keys during sync, strip local .md links
- Fix extract_tags_from_readme/notebook to return dict[str,str] preserving
sdk/topic keys instead of bare values, preventing topics like
"Customer Service" from being misclassified as SDK
- Add strip_local_md_links() to remove relative .md references that
would cause broken link errors in Docusaurus build
* ci: run test-doc-examples independently without waiting for test-rust-cli
Build the CLI directly in the job instead of downloading the artifact,
so test-doc-examples can start at the beginning in parallel with all other jobs.
* feat: webhook system with task-owned retry, retain.completed event, and UI
- New webhook system: register per-bank webhooks with HMAC signing, configurable
HTTP method/timeout/headers/params (http_config JSONB), and PATCH support
- Webhook deliveries run as async_operations (webhook_delivery type) with
task-owned retry via RetryTaskAt exception and exponential backoff
(60s / 5m / 30m / 2h / 8h, max 6 attempts)
- New retain.completed event fires per-document for both sync and async retain
- Delivery debug info (status code, response body) stored in result_metadata
- Control plane UI: webhooks tab per bank with create/edit/delete and a
deliveries table with cursor pagination and expandable response details
- 28 webhook tests covering HMAC signing, delivery retries, CRUD endpoints,
PATCH update, and retain.completed queuing
- Docs page at developer/api/webhooks documenting event payloads and delivery
- OpenAPI spec and all client SDKs (Python, TypeScript, Rust, Go) regenerated
* fix: update tests for task-owned retry model and guard _webhook_manager attribute
- test_worker.py: test_executor_exception_triggers_retry now raises RetryTaskAt
(plain exceptions are immediate failures in the new system); rename
test_executor_exception_marks_failed_after_max_retries to
test_executor_exception_marks_failed_immediately to reflect new semantics
- test_batch_api.py: remove max_retries kwarg from WorkerPoller constructor
- memory_engine.py: use getattr for _webhook_manager in _fire_retain_webhook
to avoid AttributeError when engine is created without __init__ (tests)
* fix: remove max_retries from benchmark WorkerPoller call
* fix(webhooks): transactional outbox, observations_deleted tracking, sidebar
- Queue webhook delivery rows atomically with the primary operation using the
transactional outbox pattern — prevents lost events on process crash:
- Retain (sync + async): outbox_callback passed into orchestrator.retain_batch
and called inside the DB transaction, replacing the post-commit fire call
- Consolidation: new _mark_operation_completed_and_fire_webhook combines the
status UPDATE and webhook INSERT in one transaction
- Added fire_event_with_conn() to WebhookManager for in-connection delivery
- Track observations_deleted count in consolidation stats and expose it in the
consolidation.completed webhook payload (was always None)
- Add Webhooks page to docs sidebar
- Document at-least-once delivery guarantee with operation_id dedup guidance
* fix(ui): add retain.completed to available webhook event types
* feat(ui): add delete confirmation dialog for webhooks
* fix(webhooks): include operation_id in task_payload so delivery is marked completed
The task_payload JSON was missing the operation_id field, causing execute_task
to see operation_id=None and skip _mark_operation_completed — leaving every
delivery row stuck in 'pending' forever.
Added a test that inserts a real async_operations row and verifies the status
transitions to 'completed' after a successful execute_task call.
* style: fix prettier formatting in webhooks-view
* feat: add Pydantic AI integration to CI, release pipeline, and docs
- Add test-pydantic-ai-integration job to CI (test.yml)
- Add build, publish, and artifact steps to release workflow (release.yml)
- Add hindsight-integrations/pydantic-ai to release.sh version bumping
- Add Pydantic AI documentation page (sdks/integrations/pydantic-ai.md)
- Add Pydantic AI entry to sidebar with icon
* docs: remove Requirements section from pydantic-ai integration page
* feat: add tags filtering and fix offset pagination docs for list documents API
- Add `tags` and `tags_match` query params to GET /banks/{bank_id}/documents
- Supports any, all, any_strict, all_strict matching modes (default: any_strict)
- Fix `q` param description — it's a case-insensitive substring match on document ID only
- Add tests for offset pagination and all tags_match modes
- Regenerate OpenAPI spec and Python/TypeScript/Go clients
- Document the new filtering options in docs/developer/api/documents.mdx
* fix(cli): pass new tags/tags_match args to list_documents
* feat: support timestamp="unset" to retain content without a date
When callers retain timeless content (e.g. fictional documents, static
reference material), passing timestamp="unset" now skips the utcnow()
default so mentioned_at is stored as NULL instead of an artificial date.
- HTTP: validate_timestamp recognises "unset" sentinel and threads it
through api_retain as event_date=None (key present, value None), which
the orchestrator distinguishes from key-absent (still defaults to now)
- Orchestrator: new branching logic separates "key absent" → utcnow()
from "key present but None" → no date
- types.py: RetainContent.event_date and ProcessedFact.mentioned_at are
now datetime | None; removed the unused _now_utc factory
- fact_extraction.py: all event_date params accept datetime | None;
_build_user_message emits "Event Date: Unknown" when None; removed
mentioned_at from the Fact LLM response model (LLM never sets it)
- embedding_processing: skip date suffix when fact_date is None
- entity_resolver: COALESCE(event_date, now()) for first_seen/last_seen
so entities table NOT NULL constraint is preserved
- link_utils: skip temporal linking for units without event_date
- Migration aa2b3c4d5e6f: DROP NOT NULL on memory_units.event_date
- Tests: test_retain_no_timestamp and test_retain_omit_timestamp_defaults_to_now
- Docs + OpenAPI + TypeScript client updated
* refactor: replace _TIMESTAMP_UNKNOWN sentinel with plain string comparison
The sentinel object() was only needed to distinguish "unset" from None
at the boundary — but since the field type is datetime | str | None,
"unset" can pass through the validator unchanged and be compared directly.
* chore: regenerate OpenAPI spec and clients after timestamp type change
timestamp field is now datetime | str | None to accept the "unset" sentinel value.
* feat: observation_scopes field to drive observations granularity
* fix(migration): make a2b3c4d5e6f7 a no-op to fix CI on fresh DB
The z1u2v3w4x5y6 migration already creates observation_scopes directly,
so the rename migration fails on fresh installs where observation_tags
never existed.
* chore: remove no-op migration a2b3c4d5e6f7
* feat: regenerate clients with observation_scopes field
- Add observation_scopes to OpenAPI spec and all generated clients
- Fix Rust build.rs to handle anyOf with >2 variants containing null
(previously only handled 2-item anyOf, causing progenitor to panic
on the observation_scopes union type)
* fix(rust): add observation_scopes: None to MemoryItem struct literals
* fix(api): add title to observation_scopes Field for deterministic client generation
Adding title="ObservationScopes" makes the inline anyOf schema use
the explicit name instead of deriving it from the field name, which
was non-deterministic between arm64 (macOS) and amd64 (CI) Docker.
Also fixes description: "each entity" -> "each tag".
* fix(scripts): use linux/amd64 Docker for client generation to ensure reproducibility
Both Python and Go client generation now use --platform linux/amd64
Docker, ensuring identical output on macOS arm64 (local) and Linux
amd64 (CI). Also switches Go from JAR+Java to Docker to eliminate
Java version variability.
* chore: update generated clients to API v0.4.14
* fix(test): add retry logic to test_retain_chinese_content to handle non-deterministic LLM output
* fix(test): mark test_retain_chinese_content as xfail due to non-deterministic LLM translation
* feat: filter graph memories with tags
* fix(cli): pass new q/tags/tags_match args to get_graph
* docs: use CodeSnippet for tags_match examples in recall.mdx
* fix: handle observations regeneration when memories get deleted
* feat: add clear_memory_observations endpoint and regenerate clients
- Add DELETE /banks/{id}/memories/{memory_id}/observations endpoint
- Add observations lifecycle/invalidation section to docs
- Regenerate OpenAPI spec and all clients (Python, TypeScript, Go, Rust)
* refactor: use dedicated response model for clear_memory_observations, remove code example from docs
* feat: include source facts in observation recall
* feat: include source facts in observation recall
* feat: include source facts in observation recall
* feat: include source facts in observation recall
* fix(cli): add missing source_facts field to IncludeOptions initializer
* feat: accept pdf, images and office files
* refactor: rename FileConverter to FileParser, simplify file retain API
- Rename engine/converters/ → engine/parsers/, FileConverter → FileParser,
ConverterRegistry → FileParserRegistry, MarkitdownConverter → MarkitdownParser
- Rename env var HINDSIGHT_API_FILE_CONVERTER → HINDSIGHT_API_FILE_PARSER
- Remove async/document_tags params from FileRetainRequest (always async now)
- Add retain_files() to Python Hindsight client and retainFiles() to TypeScript client
- Add sample.pdf to doc examples for working file upload demonstrations
- Update test_file_retain.py to use new parser names and always-async behavior
- Fix Go client missing os import in api_files.go
- Simplify postgresql.py storage to minimal schema
* fix: update rust CLI tests to use is_supported_file instead of is_text_file
* fix: patch Go api_files.go to add missing 'os' import after generation
* fix: insert 'os' import after 'net/url' in api_files.go patch for correct position
* chore: regenerate OpenAPI spec and clients (converter→parser description update)
* ci: add Go client integration tests
Add test-go-client job to CI workflow following the same pattern as
Python, TypeScript, and Rust client tests. The job:
- Sets up Go 1.23 with dependency caching
- Starts the Hindsight API server
- Runs integration tests using the 'integration' build tag
- Displays server logs on failure
The integration tests (hindsight-clients/go/integration_test.go) cover
all core operations: retain, recall, reflect, bank management, and
end-to-end workflows.
* Move Go cookbook content to hindsight-cookbook repo
Removes Go-specific cookbook content that was added in PR #375:
- applications/go-memory-service.md
- recipes/go-quickstart.md
- recipes/go-concurrent-pipeline.md
These have been moved to the hindsight-cookbook repository where
cookbook content should live per project conventions.
* feat(go): add CI test for Go client and patch for ogen null handling
- Add test-go-client job to GitHub Actions CI workflow
- Create post-generation patch script (patch-ogen.sh) to fix ogen's
handling of null values in optional string fields
- Patch OptString.Decode() to check jx.Next() type before decoding,
properly handling explicit null in JSON responses
The patch ensures generated code persists across regenerations and
handles the Hindsight API's nullable optional fields correctly.
Fixes: Go client integration tests for retain and bank operations
Note: Some tests still fail for nullable arrays/objects - those
require additional patches for other Opt* types.
* feat: use official go generator for Go client
* feat: use official go generator for Go client

* chore: sync Go client with latest OpenAPI spec
- Add model_child_operation_status.go (new model)
- Update model_operation_status_response.go with child operations
- Update go.mod/go.sum dependencies
- Update api/openapi.yaml
