RPG Visual Asset Production

For schema 1.6 immutable image tasks, the compiler verifies the planner task_sha256 before normalization, preserves it as source_task_sha256, and seals the fully compiled provider task with a new task_sha256. The producer verifies the compiled hash; never copy the planner hash over compiler-owned fields.

Video preflight reports every static executable, upload, and runtime-health deficiency in one result before any provider command. The capability parser accepts both legacy capability flags and the gateway endpoints form for group=video, action=create. Qwen3 ASR and Baidu OCR expose a JSON --health probe. Upload admission validates the pinned bundle marker/hash, interface, executable, and readable environment file; do not invoke the upload entrypoint with synthetic health flags.
