Announce Delivery Mode Checklist

Date: 2026-02-16 Status: completed

Scope

• Add a first-class automation delivery mode for cron/webhook runs.
• Support isolated per-run sessions while preserving outbound reply routing.

Completed

• Added automation.delivery_mode config enum in src/config/schema.ts:
  • shared_session (default)
  • isolated_job
• Implemented reply routing override in src/channels/registry.ts via metadata.replyPeerId.
• Updated CronScheduler and WebhookHandler to:
  • emit unique sender IDs per run when delivery_mode=isolated_job
  • include metadata.replyPeerId to keep output routing stable
  • include delivery metadata (deliveryMode, runId) for traceability
• Wired delivery mode through channel registration in src/daemon/channels.ts.
• Updated docs:
  • README.md automation sections
  • config/default.yaml commented template
• Added tests:
  • src/channels/registry.test.ts
  • src/automation/cron.test.ts
  • src/automation/webhooks.test.ts
  • src/config/schema.test.ts
