+# RUST-BUG-081: Stop Rust live-wire downloads after first completion
+
+## Problem
+
+The Rust hide.me live-wire harness documents that the download phase passes as
+soon as at least one started transfer completes, and the pass status uses the
+same criterion. The implementation still waited until every started transfer
+completed or the full download timeout elapsed.
+
+During `rust-hideme-20260619T021252Z`, obfuscation-on completed many transfers
+early and obfuscation-off completed one transfer early, but each pass kept
+running until the configured download window expired. That wastes public-network
+live-test time and makes the "check and intervene" loop slower without adding a
+stronger pass condition.
+
+## Acceptance
+
+- [x] The download loop returns once any started transfer completes.
+- [x] The reported completion count, bytes, progress, and source counts still
+      come from the final observed snapshot.
+- [x] Existing packet-diagnostic source-exchange evidence still runs after the
+      daemon stops.
+
+## Implementation Notes
+
+- Changed the live-wire download loop condition from "until all started
+  transfers complete" to "until one started transfer completes."
+- Added unit coverage for two started transfers where one completes and the
+  other remains incomplete.
+
+## Evidence
+
+- Live behavior exposing the issue:
+  `EMULEBB_WORKSPACE_OUTPUT_ROOT\live-wire\rust-hideme-20260619T021252Z`.
+- `python -m pytest tests/python/test_rust_live_wire_hideme.py -q`
