This release is a pre-release and may not be stable for production use.
anna-app-runtime-local
Local-dev in-memory runtime for Anna Apps. Reuses the production
anna_app_rpc_dispatcher
through WindowStoreProtocol so harness behaviour is byte-identical to
nexus production.
How it shares code with production
This package does not vendor a copy of the dispatcher. Instead it:
- Imports
dispatch,WindowStoreProtocol,HostRpcErrorfromsrc.services.anna_app_rpc_dispatcher(matrix-nexus source). - Provides
InMemoryWindowStore— aWindowStoreProtocolimpl that keeps state in dictionaries and queues SSE events in memory. - Wires the production
dispatch(store, …)against in-memory state.
Because the wheel imports src.services.… directly, the bridge process
must be launched from a Python environment that has matrix-nexus on
PYTHONPATH (typically: cd matrix-nexus && uv run python -m anna_app_runtime_local.bridge).
Public surface
from anna_app_runtime_local import LocalDispatcherSession, mint_dev_token
session = LocalDispatcherSession.create(
user_id=1,
app_slug="focus-flow",
manifest_dict={...}, # parsed manifest.json
view="main",
entry_payload={"topic": "ECM"},
)
result = await session.call("storage", "set", {"key": "x", "value": 42})
events = session.drain_events() # list[dict] for SSE relay
stdio bridge
python -m anna_app_runtime_local.bridge
Speaks JSON-RPC 2.0 over stdin/stdout (one envelope per line). Methods:
session.create→{ session_id, window_uuid, token, view, view_meta }session.call→ forwards todispatch(); returns{ ok, result | error }session.drain_events→ flushes queued SSE eventssession.close→ drops the sessionsession.refresh_token→ re-mints a dev token for an active sessionexecutas.register→ registers{tool_id, project_dir, command?}fortools.invoke; first call lazy-spawnsuv run --project <dir> <tool_id>and reuses the warm subprocess.
The Node-side harness (anna-app-cli/src/harness/bridge.ts) speaks this
protocol over python-shell.
Local HMAC tokens
mint_dev_token / verify_dev_token use a per-user key at
~/.anna-app/dev.key (mode 600, generated on first use). TTL defaults
to 30 s — shorter than production's 120 s — to surface SDK refresh bugs
early.
These tokens are not interoperable with the production JWT path;
production's _is_tool_allowed already rejects tool-dev-… prefixes.
