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.

summary: Triples query - pattern-based graph queries
|
|
description: |
|
|
Query knowledge graph using subject-predicate-object patterns.
|
|
|
|
## Triples Query Overview
|
|
|
|
Query RDF triples with flexible pattern matching:
|
|
- Specify subject, predicate, and/or object
|
|
- Any combination of filters (all optional)
|
|
- Returns matching triples up to limit
|
|
|
|
## Pattern Matching
|
|
|
|
Pattern syntax supports:
|
|
- **All triples**: Omit all filters (returns everything up to limit)
|
|
- **Subject match**: Specify `s` only (all triples about that subject)
|
|
- **Predicate match**: Specify `p` only (all uses of that property)
|
|
- **Object match**: Specify `o` only (all triples with that value)
|
|
- **Combinations**: Any combination of s/p/o
|
|
|
|
## RDF Value Format
|
|
|
|
Each component (s/p/o) uses RdfValue format:
|
|
- **Entity/URI**: `{"v": "https://example.com/entity", "e": true}`
|
|
- **Literal**: `{"v": "Some text", "e": false}`
|
|
|
|
## Query Examples
|
|
|
|
Find all properties of an entity:
|
|
```json
|
|
{"s": {"v": "https://example.com/person/alice", "e": true}}
|
|
```
|
|
|
|
Find all instances of a type:
|
|
```json
|
|
{
|
|
"p": {"v": "http://www.w3.org/1999/02/22-rdf-syntax-ns#type", "e": true},
|
|
"o": {"v": "https://example.com/type/Person", "e": true}
|
|
}
|
|
```
|
|
|
|
Find specific relationship:
|
|
```json
|
|
{
|
|
"s": {"v": "https://example.com/person/alice", "e": true},
|
|
"p": {"v": "https://example.com/knows", "e": true}
|
|
}
|
|
```
|
|
|
|
## Performance
|
|
|
|
- Default limit: 10,000 triples
|
|
- Max limit: 100,000 triples
|
|
- More specific patterns = faster queries
|
|
- Consider limit for large result sets
