* 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.
* 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: 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.
