docker compose up is partial-success-friendly — a build failure on one
service doesn't roll back the others. But the master was catching the
agent's 500 and tagging every decky in the shard as 'failed' with the
same error message. From the UI that looked like all three deckies died
even though two were live on the worker.
On dispatch exception, probe the agent's /status to learn which deckies
actually have running containers, and upsert per-decky state accordingly.
Only fall back to marking the whole shard failed if the status probe
itself is unreachable.
Enhance agent.executor.status() to include a 'runtime' map keyed by
decky name with per-service container state, so the master has something
concrete to consult.
deploy --mode swarm was failing on every heterogeneous fleet: the master
populates config.interface from its own box (detect_interface() → its
default NIC), then ships that verbatim. The worker's deployer then calls
get_host_ip(config.interface), hits 'ip addr show wlp6s0' on a VM whose
NIC is enp0s3, and 500s.
Fix: agent.executor._relocalize() runs on every swarm-mode deploy.
Re-detects the worker's interface/subnet/gateway/host_ip locally and
swaps them into the config before calling deployer.deploy(). When the
worker's subnet doesn't match the master's, decky IPs are re-allocated
from the worker's subnet via allocate_ips() so they're reachable.
Unihost-mode configs are left untouched — they're already built against
the local box and second-guessing them would be wrong.
Validated against anti@192.168.1.13: master dispatched interface=wlp6s0,
agent logged 'relocalized interface=enp0s3', deployer ran successfully,
dry-run returned ok=deployed.
4 new tests cover both branches (matching-subnet preserves decky IPs;
mismatch re-allocates), the end-to-end executor.deploy() path, and the
unihost short-circuit.
- decnet.models.DeckyConfig grows an optional 'host_uuid' (the SwarmHost
that runs this decky). Defaults to None so legacy unihost state files
deserialize unchanged.
- decnet.agent.executor: replace non-existent config.name references
with config.mode / config.interface in logs and status payload.
- tests/swarm/test_state_schema.py covers legacy-dict roundtrip, field
default, and swarm-mode assignments.
Worker agent (decnet.agent):
- mTLS FastAPI service exposing /deploy, /teardown, /status, /health,
/mutate. uvicorn enforces CERT_REQUIRED with the DECNET CA pinned.
- executor.py offloads the blocking deployer onto asyncio.to_thread so
the event loop stays responsive.
- server.py refuses to start without an enrolled bundle in
~/.decnet/agent/ — unauthenticated agents are not a supported mode.
- docs/openapi disabled on the agent — narrow attack surface.
tests/test_base_repo.py: DummyRepo was missing get_attacker_artifacts
(pre-existing abstractmethod) and so could not be instantiated. Added
the stub + coverage for the new swarm CRUD surface on BaseRepository.
