daemon: event.* fan-out (D5) + category.list/queue.list (D3) — GUI-ready
The two items aimed at pointing GUI at a real veloxd instead of mockd.
rpc/event_hub — per-subscription fan-out shared by both transports.
subscribe() registers a connection with no interest; set_filter()
(session.subscribe, replaces not adds) turns on event kinds and an
optional per-task id filter; publish() delivers a pre-built
notification to every matching subscriber. session.subscribe on both
UdsServer and WsServer now does the real thing — registers/updates a
subscription, tears it down in close_conn.
sched/scheduler — the on_engine_state hook now actually publishes:
- transition() is the one place a task's row changes state; it reads
the store's own prior row for previousState (authoritative
regardless of engine/scheduler timing), writes the error columns,
and — when a hub is supplied — publishes event.task.state with
{taskId, state, previousState, summary, error}. Wired into every
transition: scheduler-driven (admission -> probing, resume ->
connecting, pause) and engine-reported (on_engine_state).
- progress_snapshot(): one row per task the engine is tracking
(EnginePort::progress(), a new interface method backed by
DownloadHandle::progress()), plus a store side-effect
(Tasks::update_progress) so download.list/get stay current between
state transitions. Returns rows; does NOT publish itself — batching
into one array message is the caller's job, per the schema's
x-maxRateHz: 4 and AGENT-DAEMON.md item 5 ("one message per task per
tick burns a core"). main.cpp's 250 ms timerfd is that caller: one
event.task.progress per tick, only when there's something to say.
dispatcher::on_download_add now publishes event.task.added (schema:
"summary is always present so a client can insert the row without a
follow-up download.get").
store/categories, store/queues — the two D3 handlers GUI's panels
call. category.list projects the six seeded built-ins; queue.list
derives taskIds from tasks.queue_id/queue_position (Queue's own schema
note: a queue's stored row never carries membership, download.update
/ queue.reorder do).
Verified live end to end against tools/testserver: a subscribed client
sees event.task.added on add, then the full event.task.state sequence
(queued -> probing -> connecting -> downloading -> assembling ->
verifying -> complete) with correct previousState at every step, and
real category.list / queue.list results.
Tests: event_hub (filter-by-kind, filter-by-task-id, replace-not-add,
unsubscribe), store_categories_queues, plus new sched_scheduler cases
for event.task.state publishing and progress_snapshot's store
side-effect. 38 daemon/cli tests green; sched_scheduler / event_hub /
ws_server / uds_roundtrip TSan-clean.
deferrals.md: D5 mostly closed (event.task.removed and the
still-unpublished events wait on their owning D3 handlers); D3 down to
the remaining download.* verbs, rules/settings/limiter/schedule,
queue mutation, category mutation, grabber, media.

daemon: sched/scheduler — governor <-> store <-> engine, against an EnginePort seam
The Scheduler that D4 was waiting on. Built against CORE's engine
HEADERS (now in main); the real EnginePort and the veloxd wiring wait
for lane/core's stage-8 bodies to reach main (deferrals.md D4a/D4b) —
core/src/task/ is still .gitkeep there, so linking vdm::Engine now
would be an unresolved symbol.
- sched/engine_port — the abstract seam: start/pause/resume/cancel/
provide_auth/decide/refresh_url + the ADR 0011 admission config
(set_task_order / set_max_active_segments / set_host_segment_cap).
Keeps the Scheduler testable without a live engine and the daemon
unbound from the concrete vdm::Engine.
- sched/fake_engine_port — a recording impl for tests.
- sched/scheduler:
* owns the wire-UUID <-> vdm::TaskId map.
* tick(): snapshot queues (schedule window evaluated with an
injectable clock) + non-terminal tasks -> governor.evaluate ->
apply. to_start builds a vdm::task::DownloadSpec from the row and
calls EnginePort::start; to_resume -> resume(); to_pause ->
pause() + writes the pause_reason; priority_order -> set_task_order
over the mapped engine ids. `new` tasks are parked (startMode
manual) and skipped.
* on_engine_state(wire_id, state, err): projects an engine
transition onto the store row (state, pause_reason='auto' when an
error rides a paused transition per ADR 0013 §2, flattened error
columns) so the next tick sees ground truth. This is also the hook
event.task.state will fire from (D5).
* reconcile_after_restart(): CORE-owned states -> queued, paused
keeps its reason (ADR 0013 §5).
* reload_config(): reads connection.maxConcurrentDownloads /
maxActiveSegments + a daemon-local host-cap map, pushes caps to
the engine, updates the governor.
* Deps: injectable local-now clock and a post_to_loop marshaller
(engine callbacks arrive on engine threads; default runs inline
for tests).
Test veloxd.sched_scheduler (ASan+UBSan and TSan clean): admission +
ordering, a slot freeing on completion, queue-stop -> pause
(queue_stopped) then queue-restart -> resume (not a fresh start),
engine auto-pause -> pause_reason 'auto' + never auto-resumed,
reconcile_after_restart, reload_config caps push. 35 daemon/cli tests
green.
