Issue #4272: OPDS auto-download on copyparty missed books in subdirectories (and skipped folders containing only subfolders). Copyparty (?opds on any directory) emits subfolders as rel="subsection" nav entries (type="application/atom+xml;profile=opds-catalog"), files as acquisition entries with ?dl hrefs, no pagination, no "by newest" feed (template: copyparty/web/opds.xml).
Fix (PR #4948, MERGED 2026-07-06): in src/services/opds/feedChecker.ts, checkFeedForNewItems now branches: catalogs WITH a "by newest" feed keep the old behavior (newest feed + rel=next only, never crawl — whole-library subscription hazard); catalogs WITHOUT one are directory-style and get a breadth-first crawlFeeds over getSubsectionURLs (skips facet/self/up/start/top/search rels and non-catalog types), bounded by MAX_CRAWL_DEPTH=5, MAX_FEEDS_PER_CRAWL=50 (incl. root fetch), and the visited set. rel=next pagination still capped at MAX_PAGES_PER_FEED per chain. Collected entryIds are added to the local knownIds copy so a book listed by two crawled feeds is collected once (NOT persisted — failed downloads must stay retryable). Tests: src/__tests__/services/opds-feed-crawl.test.ts (mocked fetchWithAuth serving URL→XML fixtures).
Unresolved iOS half of #4272: reporter saw "33 downloads failed" on iPhone while macOS downloaded all base-dir books fine. Same TS/Rust download path both platforms (download_file in src-tauri/src/transfer_file.rs); most plausible cause is iOS suspending the app mid-sync and killing in-flight reqwest connections (35 epubs at DOWNLOAD_CONCURRENCY=3 takes minutes). Retry/backoff (MAX_RETRY_ATTEMPTS=3) picks them up on later launches, but after 3 failures entries are moved to knownEntryIds and permanently skipped with no recovery UI — a repeatedly-interrupted catalog silently loses books. Possible future work: iOS beginBackgroundTask around the sync, or don't hard-cap retries for network-type errors.
