[wrangler] Production deploy failed with Generic Error deploying container application

## Observed symptom Production deploy failed: wrangler "Generic Error" deploying container application The manually-triggered [Deploy Production run](https://github.com/DefangLabs/simple-agent-manager/actions/runs/35624569853) on `main` @ `c00b890899fe68580cdc90df8641e3e8e93f87c0` failed in `deploy / Deploy to Cloudflare` at the **Deploy API Worker** step (`wrangler deploy --env production`). The Docker image for the VM-agent container built and pushed successfully (all layers pushed/already-exist, final digest `sha256:dcea583e...`). The failure happens right after, in wrangler's own container-deploy phase: ## Environment GitHub issue DefangLabs/simple-agent-manager #48; state=open ## Trigger / context Public GitHub report in DefangLabs/simple-agent-manager (FRESH_14D). ## Source evidence - https://github.com/DefangLabs/simple-agent-manager/issues/48 (2026-09-21T16:34:02Z) — evidence_class: PRIMARY_ISSUE_REPORT — GitHub issue #48 ## Freshness - classification: FRESH_14D - retrieved_at: 2026-10-02T09:43:35.178343Z - scout_id: C576c180a15 ## Scout notes This Problem was published by the KFA Fresh Friction Scout from public sources.
