The bridge passes a `can_u Sessions are keyed by Inkbox contact, so one person = one conversation across channels. Claude session ids are persisted in `~/.inkbox-claude/sessions.json` and resumed across bridge restarts — your conversation picks up where it left off. Replies go out on the channel you last used.

SMS, email, and voice have no typing indicator, so this is iMessage-only. **Delivery failures.** An outbound message can die two ways, and the bridge feeds both into one delivery-failure loop. It can be **rejected at send time** — the server's content policy blocks it (markdown artifacts, emoji overload), the recipient has opted out, the address is bad, or the body is too long — which comes back as an error on the send call. Or it can be **accepted and then fail downstream** — a carrier filters the SMS, an iMessage is declined, an email bounces — which Inkbox reports asynchronously (`text.delivery_failed`/`text.delivery_unconfirmed`, `imessage.delivery_failed`, `message.bounced`/`message.failed`). Either way the bridge wakes the affected contact's session to tell Claude *which* message didn't land and *why*, so it can fix and resend or reach you another way using its Inkbox tools. The wake-up runs as a side-effect turn — Claude acts via tools rather than replying on the channel that just failed. Sends are **hard-capped at three per logical reply** with the budget shared across both surfaces (keyed by conversation/recipient): after that the thread goes quiet with a loud log line instead of looping. The budget resets on a fresh inbound, a delivered receipt, or a 30-minute TTL, and repeat webhooks for the same message are de-duplicated. Transient (5xx) send failures are excluded — a bare resend clears those. @@ -247,6 +249,7 @@ Beyond Inkbox's own events, the `/webhook` endpoint can wake the agent for event | `INKBOX_SKIP_WEBHOOK_RECONCILE` | no | `false` | Leave webhook subscriptions untouched on start.
