v1.1.0

Minor Changes

• 9d92372: Add metadata layer (AniList, MAL/Jikan, Kitsu) and unify IDs as URNs

  • Metadata providers: AnilistMeta (full enrichments: relations, characters with voice actors, staff, recommendations, externalLinks, streamingEpisodes), MalMeta (Jikan filler/recap + relations + browse), KitsuMeta (cross-source mappings).
  • MappingClient: resolves a metadata record onto a content provider's raw media ID via a four-step waterfall — cache → provider.lookupByMapping → MALSync + Anify (raced) + arm-server enrichment → fuzzy title search with composite similarity (Sørensen–Dice + token Jaccard + prefix), year + catalogType discriminators, and an episode-count cross-check.
  • Unified URN ID space: every id flowing through the SDK has shape ${providerId}:${rawId} (e.g. allmanga:5jzpRTJW, anilist:21, mal:anime:21). Helpers: buildUrn, parseUrn, unwrapUrn, strictUnwrapUrn, buildTypedUrn, parseTypedUrn.
  • BaseProvider upgrades: optional lookupByMapping(mappings) for provider-native cross-source lookups (MegaPlay opts in — its media ID is the AniList ID), static malsyncSites declaration, per-provider concurrency cap.
  • Transport hardening: per-host token-bucket rate limiter with built-in policies for the catalogue APIs, exponential-backoff retry honouring Retry-After, real AbortSignal propagation, curl fallback extracted into a pluggable HttpTransport interface.
  • Server: new /meta/search, /meta/info, /meta/content, /meta/stream, /meta/tracks, /meta/browse, /health, /openapi.json routes. Dynamic proxyBase derived from the request Host header. Optional HMAC-signed /proxy URLs (proxySignSecret) and suffix-matched SSRF allowlist (proxyAllowedHosts).
  • IContentUnit enrichment: when used through the metadata layer, content units carry per-episode metadata (title, thumbnail, filler/recap flags) folded in from the catalogue.
  • Absolute-episode rescue: walks PREQUEL relations to compute a season offset for multi-season titles where the meta record's per-season numbering misaligns with the content provider's continuous list.
  • Tests: 118 tests, all real (no mocks, no fixtures, no graceful skipping). CLAUDE.md carries the testing rule explicitly.
