ComfyUI's own queue and its own socket, not a second one alongside them. A
FunPack queue would be a second thing tracking what is running, and the one the
user believes is whichever spoke last -- so this speaks to /prompt, /interrupt
and /ws as any ComfyUI client does and holds only a view of the server's state.
The graph is asked for, never assembled here, for the same reason.
The client id is remembered: ComfyUI addresses progress to the client that
queued the run, so a reload with a fresh id hears nothing about the generation
already in flight -- the run continues, the GPU time is spent, and the app says
Ready.
Faults found on the way, each in code that already had passing tests:
* `[hidden]` was inert across the whole kit. The UA rule is element-level, so
`.cx-btn { display: inline-flex }` beats it -- Cancel was marked hidden, sat
there, and nothing reported anything. jsdom cannot see it: the attribute was
always correct. One reset rule, and a browser test over four element kinds.
* A panel passed no height to its body and a split pane passed none to its
panes, so the viewer asked for 100% of `auto` and collapsed to a single line
inside a panel that was the right size around it.
* subscribe() delivered the first state outside the guard every later delivery
gets, so one bad listener took down whoever was wiring the UI up -- at
startup, before anything existed to report it.
* A whole tests directory was never run: the test script globbed
composer/tests only. `node --test` discovers them itself now, so there is no
list to forget.
* `empty` was not in the content rule's key list, so three elements were never
asked to prove their empty-state text comes back as text rather than markup.
The dev server now mounts the REAL routes -- register() already took a route
table -- instead of reimplementing them over http.server. It answered POST
/api/pipeline with 501, so the edit-and-queue path could not be looked at, which
is the one thing the dev server exists for.
