# RB-05 MAJOR: poll_inference treats IPC listener loss as session-fatal

**Severity:** MAJOR
**Path:** `src-tauri/src/commands/live.rs:721-813`
**Source:** [2026-04-22 code review](../code-review-2026-04-22.md)
**Labels:** release-blocker, major, ipc-lifecycle

## Problem

`result_channel.send(...)` propagates with `?`, so closing the listening frontend or reloading the webview terminates the whole live session — even when capture and inference are healthy. Tauri channel-lifecycle events are not transcription failures and should not kill the worker.

## Acceptance

- Channel-send errors log a warning and continue the session (if recoverable) or terminate gracefully (if the session was going to end anyway).
- The distinction between "transcription failed" and "no listener to report to" is explicit in the error handling.
- Regression test: simulate channel close mid-session, assert the worker keeps capturing and produces a valid WAV file.

## Fix scope

Medium. Isolated to `poll_inference` and its error handling; interacts with RB-04 (monolith refactor) since that restructures the same function family.
