A dropped proxy connection (EOF) or 5xx on the task-create failed the whole generation. submitTask now retries transient (ErrTemporaryUpstream) submits up to 3x with backoff, honoring ctx. Applies to both Nano Banana image and Gen-4 video. Validated: 10/10 4K images (19-24MB PNG each) generated across 10 accounts.
Extends the adobe split to leonardo, krea, imagine, runway (image+video) and chatgpt: reference-image upload, polling and result download egress on the local IP; only the generate/task-create submit uses proxy.url. chatgpt keeps its anti-bot-guarded submit+upload phase on the proxy and moves only the existing second (poll/resolve/download) session to local. custom is already direct. Build+vet pass; adobe verified live, the other providers are code-complete but not yet live-tested (no dev accounts).
Full Go backend + Vue 3 frontend, OpenAI-compatible API, multi-provider
account pools, billing/admin, Docker one-command deploy with auto HTTPS.
