| description | Govern queue ownership, backpressure, retry and cancel semantics, and mutual-exclusion behavior across STARFRAME local apps. Use when `9040`, `9041`, bridge queues, or operator queue surfaces change together. |
Cross-App Queue Backpressure Governance
Use this skill when queue behavior spans more than one STARFRAME app or worker surface.
Workflow
- Identify the true queue owners before changing any client surface.
- Inspect queue depth, retry, cancel, and recovery behavior across the affected apps.
- Check mutual-exclusion and heavy-lane ownership rules before enabling parallel execution.
- Keep operator-visible queue state aligned with the backend owner.
- Re-run a bounded queue proof after changes land.
Required Evidence
- queue owners involved
- backpressure or mutual-exclusion rule touched
- retry, cancel, or recovery proof
- operator-visible queue/status surface checked
Guardrails
- Do not invent a second queue owner.
- Do not let a client redefine retry or cancel rules owned elsewhere.
- Fail closed if queue truth and UI truth drift.
- Keep heavy-lane exclusivity explicit when
9040 and 9041 are involved.

Scope Boundary
Use this skill only for cross-app queue ownership, backpressure, and recovery governance.
For a single repo's queue contract, route to that repo's more specific worker skill.
