Stability: - transient timeouts no longer classified as ISP blocking; they fall through to retry backoff (hard blocks - DNS/RST/cert - still abort) - connectivity change now closes idle Go connections in every network mode (debounced), so pooled sockets from the old interface are not reused after a wifi/cellular handoff - download body reads get a 60s stall watchdog that cancels and surfaces a retryable network error instead of hanging; distinct from user cancellation - ResponseHeaderTimeout 45s on all transports; IdleConnTimeout 90->60s; dial timeout 30->10s; retry backoff gains full jitter; Retry-After honored on 5xx and Deezer 429 Data usage / speed: - cover downloads deduplicated with singleflight plus a 24MB/15min in-memory cache keyed by final URL (album batches fetched the same 1800px cover once per track before) - song.link availability cached (30min positive / 5min negative) in front of the 9-req/min rate limiter - uTLS Cloudflare path now pools one HTTP/2 connection per host with a shared TLS session cache instead of a full handshake per request Deezer artist track-count N+1 kept: counts feed the discography download UI and are already amortized by the artist TTL cache.
