acp agent switch stops active seller runtime, orphaning incoming jobs

[OnChainAIIntel]

Environment

• openclaw-acp commit: <SHA_PENDING>
• Node: <VERSION_PENDING>
• OS: macOS Sonoma (Apple Silicon)
• Chain: Base mainnet

Observed behavior

When a seller agent's runtime is active (acp serve start), running acp agent switch <other> stops the seller's WebSocket connection to the ACP server. If a job REQUEST is submitted to the seller during this window, the job lands server-side but the seller is offline. When the seller later reconnects (via acp agent switch <seller> → acp serve start), the pending job is not replayed. The job hangs in REQUEST phase indefinitely.

Reproduction

1. acp agent switch pqs-atlas-seller
2. acp sell create pqs_atlas_score
3. acp serve start
4. In a second terminal: acp agent switch pqs-buyer — seller runtime stops (unexpected side effect of switching the active agent)
5. acp job create <seller-wallet> pqs_atlas_score --requirements '{"prompt":"...","vertical":"general"}'
6. Job is created server-side but the seller socket is offline. Job phase stays REQUEST.
7. acp agent switch pqs-atlas-seller → acp serve start — seller reconnects, but the pending job is not replayed. Verified with job 1003481568, which sat in REQUEST for >10 minutes with a live seller runtime, never progressing.

Expected behavior

Any of:

• (a) acp agent switch preserves running seller runtimes for non-active agents
• (b) Seller runtime replays pending REQUEST jobs on reconnect
• (c) CLI warns the user when acp agent switch is about to stop an active runtime, with a --force override

Workaround we're using

Bypassed the CLI for job creation. POSTed directly to https://claw-api.virtuals.io/acp/jobs with the buyer's x-api-key while the seller runtime stays online and continuously bound to its active agent. Job 1003481624 completed successfully with this pattern:

• Buyer → escrow: https://basescan.org/tx/<TX1_PENDING>
• Escrow → seller: https://basescan.org/tx/<TX2_PENDING>

Context

Discovered while building a grade-gated prompt-scoring service on ACP for the Anthropic Built with Opus 4.7 hackathon (April 2026). Happy to contribute a PR if the fix direction is clarified — (a) seems like the lowest-risk change.
