Replaces raw string queries with structured `SearchQuery` types across the `MusicSource` trait and UPnP handlers. Adds dedicated paginated endpoints, explicit caching, and type-specific filtering for the Qobuz source. Fixes a frontend navigation bug by aligning state management with UPnP browse semantics and properly routing virtual container IDs. Also updates the Makefile for dynamic `RUST_LOG` configuration, standardizes logging with `tracing`, and adds the dependency lockfile.
Append sections 7–9 to the architecture roadmap detailing implementation steps for API robustness (request signing, audio metadata, stream restriction parsing, quality fallback, and rate-limit handling), multi-category search endpoints, and editorial discovery. Also update the priority tracking table to reflect these new tasks.
Parallelize Qobuz playlist track fetching by increasing the page size to 500 and processing remaining pages concurrently via `futures::try_join_all` with a configurable semaphore (default 3). Results are offset-sorted to preserve original order. Adds a `page_concurrency` configuration option, updates the API client initialization, and introduces the `futures` dependency. This reduces large playlist latency from ~1.6s to ~0.7s.
Replaces sequential track requests with a chunked batch enrichment workflow using MD5-signed POST requests (50-ID windows). Introduces cache-first fetching, order preservation via HashMap lookups, and graceful fallbacks for playlist and favorite loading.
Refactor Qobuz bundle fetching to improve resilience and performance. Add HTTP timeout and retry configuration, and implement a retry loop that returns version metadata. Introduce bundle version caching and persistence to skip redundant extractions when the bundle remains unchanged. Replace console logging with structured tracing macros and update the architectural tracking document to mark these improvements as complete.
Introduce a `/tracks/:id/flac` endpoint and `open_cmaf_stream` client method to enable incremental decryption and caching of FLAC audio. Refactor segment decryption into a reusable helper and stream decrypted frames via a bounded tokio channel. Add `tokio-util` as an optional dependency, update the `pmoserver` feature, and implement conditional routing for local proxy versus direct API access. Update the architecture roadmap to document these improvements.
