Summary

Version: OpenClaw 2026.6.1 (2e08f0f)
OS: macOS

Bug: When a delivery fails, the gateway retry mechanism cycles through
active sessions as relay vehicles, bypassing delivery.mode=none. This
corrupts the sessions being used as relays, causing LLM schema errors
on next startup.

Pattern observed:

• Agent sends message, believes it sent
• Delivery retry fires on alternating channels (webchat → unknown)
• Same payload delivered 3x in a row
• Sessions used as relay vehicles become corrupted
• Affected agents hit "LLM request failed: provider rejected the request
  schema or tool payload" on next turn

Workaround: Manual session clear via sessions.json + gateway restart.

Expected behavior: Retry logic should not use active persistent main
sessions as relay vehicles. delivery.mode=none should be respected at
the retry layer.

Steps to reproduce

1. Run a multi-agent fleet with persistent main sessions on multiple agents (coordinator, vice-chair, cortex).
2. Agent attempts to send a message via sessions_send tool.
3. Delivery fails on primary channel.
4. Gateway retry mechanism fires — cycles through active persistent main sessions as relay vehicles.
5. Same payload delivered 3x on alternating channels (webchat → unknown).
6. Affected relay sessions become corrupted.
7. On next startup, corrupted agents hit "LLM request failed: provider rejected the request schema or tool payload."

Expected behavior

Retry logic should not use active persistent main sessions as relay vehicles. delivery.mode=none should be respected at the retry layer. Retries should fail gracefully without corrupting unrelated sessions.

Actual behavior

Gateway retry selector bypasses delivery.mode=none by cycling active sessions as relay vehicles. Results in session corruption, LLM schema errors on next startup, and repeated delivery of the same payload on alternate channels. Workaround: manual session clear via sessions.json + gateway restart.

Impact and severity

Affected: All persistent main sessions fleet-wide (16 agents).
Severity: Blocks workflow — corrupted sessions require manual
intervention to clear (sessions.json edit + gateway restart) before
affected agents can function.
Frequency: Intermittent — triggers when delivery fails on a session
that has active persistent main sessions running.
Consequence: Agent downtime, repeated duplicate message delivery
on alternate channels, manual recovery required each occurrence.
In a production multi-agent RIA compliance fleet, this causes
unplanned outages during business hours.
