Bus topic segments are NATS-style tokens and the validator at
bus/topics.py:402 rejects '.', '*', '>', whitespace. My W3 constants
'service.added' / 'service.removed' tripped this on every live
add/remove call:
ValueError: topic segment 'service.added' may not contain '.', ...
Renamed both to underscore form: DECKY_SERVICE_ADDED = 'service_added'.
Aligned the SSE forwarder's name mapping (decky.<name>.service_added →
SSE event 'decky.service_added') and the frontend's
useTopologyStream listener + MazeNET.tsx event handler. Also updated
the wiki entry with a note about the underscore.
When topoStatus is active/degraded, editor.updateDecky enqueues into
the mutator queue and returns {kind:'enqueued'}. The palette-drop
handler then short-circuits on that and never updates local state, so
a service dragged onto a deployed decky just vanishes — what ANTI saw
as 'no way to APPLY'.
Same gap on the design-time 'REMOVE SERVICE' button in the Inspector's
service detail panel: enqueue + no local update = chip stays.
Both now route through liveAddService / liveRemoveService when the
topology is active, hitting POST/DELETE /topologies/{id}/deckies/{name}/services
directly and patching local state from the response. Pending
topologies still queue through the mutator (correct: no live
containers to mutate).
Hoisted serviceRegistry / liveAddService / liveRemoveService above
the palette-drop callback so the deps array doesn't trip the const
TDZ at render time.
The /topologies/{id}/events SSE proxy now subscribes to two bus
patterns concurrently and merges them through a bounded asyncio.Queue:
* topology.{id}.> — lifecycle (status, mutation.*) — unchanged.
* decky.> — per-decky events, filtered by payload.topology_id
so a fleet decky sharing a name with a topology
decky doesn't leak across.
_sse_name_for routes 'decky.<name>.service.added' to the SSE event
name 'decky.service.added' (kept the prefix so the frontend doesn't
collide with topology lifecycle events that share leaf names like
'status').
useTopologyStream surfaces the two new event names; MazeNET.tsx's
onStreamEvent optimistically patches the matching node's services
list so a second tab reflects shape changes without a refetch.
When the topology is active/degraded the Inspector switches services
chips into live controls: each chip gets a × button that DELETEs to
the W3 endpoint, and a dashed '+ ADD' chip opens a typeahead picker
fed by useServiceRegistry().perDecky.
Pending topologies still use the existing design-time path
(onRemoveService → editor.updateDecky); the Inspector picks based on
topologyStatus, so an operator never accidentally hits a live API
call against a topology that isn't deployed yet.
The mutation handlers in MazeNET.tsx hit POST/DELETE
/api/v1/topologies/{id}/deckies/{name}/services{,/svc} and
optimistically apply the response's services list to local state.
Cross-tab reconciliation rides on the SSE forwarder shipped in the
follow-up commit.
