Nothing calls search_indexers yet, which is expected at this phase.

search_indexers loops sequentially. RSS sync (§6.2) hits every indexer on a ~10 minute cadence, and the client timeout is 30s, so a handful of hanging indexers serialises past that cadence — 20 indexers is a 10 minute worst case on its own.

ProwlarrClient is Clone, so a tokio::task::JoinSet fan-out works without adding a dependency; sort the results back into indexer_ids order.

An item with a guid but no <enclosure> and no <link> survives finish() with download_url: None.

arr_core::Release.download_url is a non-optional String, and a release with no URL can never be grabbed. Make download_url required here the same way name is, so the item is dropped at parse time rather than downstream.

set_text trims each chunk and append_text joins them with no separator, so any value split across events loses the whitespace at the split.

<title>Movie <![CDATA[& More]]> 2026</title> yields Movie& More2026 — quick-xml emits Text/CData/Text, each trimmed, then concatenated. Trim once in finish() instead of per chunk.

attribute() returns Err(InvalidResponse) on a malformed attribute and the ? here propagates out of parse_releases, so one bad attribute anywhere in the feed discards every item from that indexer.

The issue's requirement is isolation between indexers, which this meets, but a partial feed is more useful than none — treat an unreadable attribute as absent.

Nothing in the test asserts name, guid or download_url.

The fixtures were built to exercise exactly those: a CDATA title (beyond-hd), a CDATA link carrying a token and an <enclosure>/<link> pair that tests the precedence in finish() (torrentleech), and an isPermaLink="true" guid (iptorrents). None of it is checked, so the CDATA and enclosure-over-link paths are untested.

Addressed all five findings in 0c766ca: concurrent per-indexer fan-out with stable ordering, required download URLs, whitespace-safe mixed text/CDATA parsing, tolerant optional attributes, and assertions for the recorded fixture fields.

just ci passes all 94 tests. The earlier movie API failure was a stale local arr-db artifact after merging migration 0003; rebuilding that package fixed the workspace binary without a source change.

Reviewed 3e2ed5d. No findings.

All five from the previous pass are addressed in 0c766ca, and I checked the fixes rather than just the intent:

  • JoinSet fan-out keeps the result order and maps a lost task to SearchError::Task.
  • download_url is required, guid falls back to it, so an ungrabbable item is dropped at parse time.
  • Dropping trim_text and trimming once in cleaned() fixes the split-text case; the new test pins Movie & More 2026.
  • The fixture change (torrentleech <link> now a details URL) makes enclosure-over-link precedence actually testable, and it is tested.
  • attribute() skipping a malformed attribute is correct, not a silent truncation: quick-xml's IterState::next sets State::Next(offset) on ExpectedEq, so iteration resumes at the next attribute — which is what the <enclosure broken url=… /> case in the new test proves.
