The agent reported its state only on the adaptive sync tick (3s watching /
10s idle), so a resolving→downloading→verifying→organizing→completed
transition could lag up to a full interval before the server (and the web
UI) saw it. Now every successful Task.Transition fires an onChange hook
wired to TriggerSync, pushing the new state immediately. Bursts are safe:
TriggerSync is a buffered-1 send, so clustered transitions coalesce into
one sync.
- Task gains an onChange hook fired AFTER the status mutex is released
(so a future heavier hook can't deadlock on task.mu); nil is a no-op.
- Manager.OnStateChange is set on each task at Submit; the daemon wires it
to TriggerSync alongside the existing OnTaskDone.
- Stream tasks transition outside the Manager, so handleStreamTask wires
the same hook explicitly (gap found in review) — resolving/downloading/
completed/failed on the stream path now push too.
The adaptive ticker stays as a reconciliation heartbeat; it's just no
longer the latency floor for state changes.
DebridDownloader receives directUrl from the server and downloads via
plain HTTPS with progress reporting, resume (Range), and pause/cancel.
- Add DirectURL, DirectFileName to agent Task and engine Task types
- Implement DebridDownloader: HTTPS download with progress, resume, cancel
- HTTP client with 30s ResponseHeaderTimeout
- Safe shortID helper to prevent slice panic on short IDs
- Validate 416 against Content-Range server size for resume integrity
- Register debridDl in daemon and one-shot download command
- Tests: available, download, resume, cancel, pause, fallback filename,
expired URL (410), unauthorized (401), shutdown, task propagation
