[bug] video ref async tasks fail immediately after a successful dry-run

Environment

• CLI: bl 1.18.1
• Skill: bailian-protocol / bailian-gen 1.18.1
• Node: v24.18.0
• OS: macOS 14.8.7 (23J520)
• Region: cn-beijing (account and endpoint redacted)

Reproduce

bl video ref --async --output json \
  --model wan3.0-video \
  --image ~/path/to/shot05.png \
  --image ~/path/to/shot07.png \
  --image-voice ~/path/to/music.wav \
  --resolution 1080P --ratio 9:16 --duration 15 --watermark false \
  --prompt "[redacted: image-1 to image-2 music-synchronised studio performance]"

The same request with --dry-run --output json succeeds and returns a valid payload containing two reference_image media objects and one reference_audio media object.

Expected

The asynchronous request should enter queue/processing, or return a structured validation, quota, content, or service error explaining why it cannot run.

Actual

The submission returns a task ID, then the task is marked FAILED about two to three seconds later. bl video task get --output json --verbose returns HTTP 200 and only the task status/timestamps, without an error code, reason, hint, or failure detail.

Evidence

Task ID	Result	Submit / end	Request ID from verbose task query
42e2da41-ab3d-463a-9fc1-b1b23336ee6b	FAILED	2026-09-01 12:14:19 → 12:14:21	99a1470e-d9cb-9b06-8e95-37bee72b3fc0
a86a9582-5844-4793-a2a7-3e98848c016b	FAILED	2026-09-01 12:32:55 → 12:32:57	not captured
2c12812c-e47d-4f26-96d7-5c028def31fb	FAILED	2026-09-01 12:47:37 → 12:47:39	5c544fac-4335-9bec-8aa0-e2745b10feca

The account was reported recharged before the last two submissions; the symptom remained unchanged. bl auth status was healthy. No CLI/skill version mismatch was present. Search for open duplicates with gh issue list --repo modelstudioai/cli --search "video ref task FAILED dry-run" --state open --limit 10 returned no results.

Frequency

Always for this request path in this environment (three consecutive paid async submissions following a successful dry-run).

Requested investigation

Please expose the provider-side failure reason through bl video task get, or clarify whether this wan3.0-video reference-to-video configuration has an account/region-side restriction that is not surfaced in the task response.
