* CLI auth migration, document embeddings core lifecycle (#913)
Migrate get_kg_core and put_kg_core CLI tools to use Api/SocketClient
with first-frame auth (fixes broken raw websocket path). Fix wire
format field names (root/vector). Remove ~600 lines of dead raw
websocket code from invoke_graph_rag.py.
Add document embeddings core lifecycle to the knowledge service:
list/get/put/delete/load operations across schema, translator,
Cassandra table store, knowledge manager, gateway registry, REST API,
socket client, and CLI (tg-get-de-core, tg-put-de-core).
Fix delete_kg_core to also clean up document embeddings rows.
* Remove spurious workspace parameter from SPARQL algebra evaluator (#915)
Fix threading of workspace paramater:
- The SPARQL algebra evaluator was threading a workspace parameter
through every function and passing it to TriplesClient.query(),
which doesn't accept it. Workspace isolation is handled by pub/sub
topic routing — the TriplesClient is already scoped to a
workspace-specific flow, same as GraphRAG. Passing workspace
explicitly was both incorrect and unnecessary.
Update tests:
- tests/unit/test_query/test_sparql_algebra.py (new) — Tests
_query_pattern, _eval_bgp, and evaluate() with various algebra
nodes. Key tests assert workspace is never in tc.query() kwargs,
plus correctness tests for BGP, JOIN, UNION, SLICE, DISTINCT, and
edge cases.
- tests/unit/test_retrieval/test_graph_rag.py — Added
test_triples_query_never_passes_workspace (checks query()) and
test_follow_edges_never_passes_workspace (checks query_stream()).
* Make all Cassandra and Qdrant I/O async-safe with proper concurrency controls (#916)
Cassandra triples services were using syncronous EntityCentricKnowledgeGraph
methods from async contexts, and connection state was managed with
threading.local which is wrong for asyncio coroutines sharing a single
thread. Qdrant services had no async wrapping at all, blocking the event
loop on every network call. Rows services had unprotected shared state
mutations across concurrent coroutines.
- Add async methods to EntityCentricKnowledgeGraph (async_insert,
async_get_s/p/o/sp/po/os/spo/all, async_collection_exists,
async_create_collection, async_delete_collection) using the existing
cassandra_async.async_execute bridge
- Rewrite triples write + query services: replace threading.local with
asyncio.Lock + dict cache for per-workspace connections, use async
ECKG methods for all data operations, keep asyncio.to_thread only for
one-time blocking ECKG construction
- Wrap all Qdrant calls in asyncio.to_thread across all 6 services
(doc/graph/row embeddings write + query), add asyncio.Lock + set cache
for collection existence checks
- Add asyncio.Lock to rows write + query services to protect shared
state (schemas, sessions, config caches) from concurrent mutation
- Update all affected tests to match new async patterns
* Fixed error only returning a page of results (#921)
The root cause: async_execute only materialises the first result
page (by design — it says so in its docstring). The streaming query
set fetch_size=20 and expected to iterate all results, but only got
the first 20 rows back.
The fix uses
asyncio.to_thread(lambda: list(tg.session.execute(...)))
which lets the sync driver iterate
all pages in a worker thread — exactly what the pre-async code did.
* Optional test warning suppression (#923)
* Fix test collection module errors & silence upstream Pytest warnings (#823)
* chore: add virtual environment and .env directories to gitignore
* test: filter upstream DeprecationWarning and UserWarning messages
* fix(namespace): remove empty __init__.py files to fix PEP 420 implicit namespace routing for trustgraph sub-packages
* Revert __init__.py deletions
* Add .ini changes but commented out, will be useful at times

* Fix publisher resource leak in librarian submit_document (#883)
Wrap pub.start()/pub.send() in try/finally to guarantee pub.stop() is
called on error. Remove unnecessary asyncio.sleep(1) kludge.
* Make Cassandra replication factor configurable (issue #787) (#887)
Add CASSANDRA_REPLICATION_FACTOR environment variable and
--cassandra-replication-factor CLI argument to cassandra_config.py.
Update all four table store constructors (ConfigTableStore,
KnowledgeTableStore, LibraryTableStore, IamTableStore) to accept
an optional replication_factor parameter and use it in keyspace
creation CQL queries.
Thread the replication factor through all service constructors:
Configuration, KnowledgeManager, Librarian, IamService, and
knowledge store Processor.
* Update tests

Introduces `workspace` as the isolation boundary for config, flows,
library, and knowledge data. Removes `user` as a schema-level field
throughout the code, API specs, and tests; workspace provides the
same separation more cleanly at the trusted flow.workspace layer
rather than through client-supplied message fields.
Design
------
- IAM tech spec (docs/tech-specs/iam.md) documents current state,
proposed auth/access model, and migration direction.
- Data ownership model (docs/tech-specs/data-ownership-model.md)
captures the workspace/collection/flow hierarchy.
Schema + messaging
------------------
- Drop `user` field from AgentRequest/Step, GraphRagQuery,
DocumentRagQuery, Triples/Graph/Document/Row EmbeddingsRequest,
Sparql/Rows/Structured QueryRequest, ToolServiceRequest.
- Keep collection/workspace routing via flow.workspace at the
service layer.
- Translators updated to not serialise/deserialise user.
API specs
---------
- OpenAPI schemas and path examples cleaned of user fields.
- Websocket async-api messages updated.
- Removed the unused parameters/User.yaml.
Services + base
---------------
- Librarian, collection manager, knowledge, config: all operations
scoped by workspace. Config client API takes workspace as first
positional arg.
- `flow.workspace` set at flow start time by the infrastructure;
no longer pass-through from clients.
- Tool service drops user-personalisation passthrough.
CLI + SDK
---------
- tg-init-workspace and workspace-aware import/export.
- All tg-* commands drop user args; accept --workspace.
- Python API/SDK (flow, socket_client, async_*, explainability,
library) drop user kwargs from every method signature.
MCP server
----------
- All tool endpoints drop user parameters; socket_manager no longer
keyed per user.
Flow service
------------
- Closure-based topic cleanup on flow stop: only delete topics
whose blueprint template was parameterised AND no remaining
live flow (across all workspaces) still resolves to that topic.
Three scopes fall out naturally from template analysis:
* {id} -> per-flow, deleted on stop
* {blueprint} -> per-blueprint, kept while any flow of the
same blueprint exists
* {workspace} -> per-workspace, kept while any flow in the
workspace exists
* literal -> global, never deleted (e.g. tg.request.librarian)
Fixes a bug where stopping a flow silently destroyed the global
librarian exchange, wedging all library operations until manual
restart.
RabbitMQ backend
----------------
- heartbeat=60, blocked_connection_timeout=300. Catches silently
dead connections (broker restart, orphaned channels, network
partitions) within ~2 heartbeat windows, so the consumer
reconnects and re-binds its queue rather than sitting forever
on a zombie connection.
Tests
-----
- Full test refresh: unit, integration, contract, provenance.
- Dropped user-field assertions and constructor kwargs across
~100 test files.
- Renamed user-collection isolation tests to workspace-collection.
* Tech spec
* Address multi-tenant queue option problems in CLI
* Modified collection service to use config
* Changed storage management to use the config service definition
