This is the unblock for the wizard hang. Both endpoints used to run
docker compose synchronously inside the HTTP handler -- on master
(unihost) or via asyncio.gather of worker /deploy POSTs at 600s
timeout each (swarm) -- blocking every other API request.
New flow:
1. Commit the new config shape to repo state (fast).
2. Create one DeckyLifecycle row per decky (status=pending).
3. Spawn asyncio.create_task(run_deploy / run_mutate) -- the
lifecycle runner drives rows through running -> succeeded|failed
and emits decky.<name>.lifecycle on the bus.
4. Return 202 with {lifecycle_ids: [...]}. Wizard polls
GET /deckies/lifecycle?ids=... (next commit).
mutator/engine.py gains pick_new_services() -- shared between the
async API path and the watch-loop's synchronous mutate_decky().
DeployResponse grows lifecycle_ids[]. The old dispatch_decnet_config
helper still exists for the CLI swarm-deploy command path; it just
isn't called from the API handler anymore.
Test changes: 200 -> 202, drop dispatch_decnet_config mocks (handler
no longer calls it), assert lifecycle_ids in response + committed
state matches expectations.
Wi-Fi APs bind one MAC per associated station, so VirtualBox/VMware
guests bridged over Wi-Fi rotate the VM's DHCP lease when Docker's
macvlan starts emitting container-MAC frames through the vNIC. Adds a
`use_ipvlan` toggle on the Agent Enrollment tab (mirrors the updater
daemon checkbox): flips the flag on SwarmHost, bakes `ipvlan=true` into
the agent's decnet.ini, and `_worker_config` forces ipvlan=True on the
per-host shard at dispatch. Safe no-op on wired/bare-metal agents.
Deckies merged in from a prior deployment's saved state kept their
original host_uuid — which dispatch_decnet_config then 404'd on if that
host had since been decommissioned or re-enrolled at a different uuid.
Before round-robin assignment, drop any host_uuid that isn't in the live
swarm_hosts set so orphaned entries get reassigned instead of exploding
with 'unknown host_uuid'.
POST /deckies/deploy now branches on DECNET_MODE + enrolled host presence:
when the caller is a master with at least one reachable swarm host, round-
robin host_uuids are assigned over new deckies and the config is dispatched
via AgentClient. Falls back to local docker-compose otherwise.
Extracts the dispatch loop from api_deploy_swarm into dispatch_decnet_config
so both endpoints share the same shard/dispatch/persist path. Adds
GET /system/deployment-mode for the UI to show 'will shard across N hosts'
vs 'will deploy locally' before the operator clicks deploy.
