anna-app-runtime-local 0.2.0a2

Local-dev in-memory runtime for Anna Apps. Wraps anna-app-core's dispatcher with an InMemoryWindowStore + WebSocket bridge.

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:

1. Imports dispatch, WindowStoreProtocol, HostRpcError from src.services.anna_app_rpc_dispatcher (matrix-nexus source).
2. Provides InMemoryWindowStore — a WindowStoreProtocol impl that keeps state in dictionaries and queues SSE events in memory.
3. 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 to dispatch(); returns { ok, result | error }
• session.drain_events → flushes queued SSE events
• session.close → drops the session
• session.refresh_token → re-mints a dev token for an active session
• executas.register → registers {tool_id, project_dir, command?} for tools.invoke; first call lazy-spawns uv 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.
