+### Miruro providers
+
+Choose **Playback → Miruro → Video Host** or **Caption Provider** in Terebi's menu bar, or use **gear → Miruro**, to change providers for the session. Video and caption providers are independent; available names come from the episode response. These menus do not write the config file.
+
+Optional startup preferences:
+
+```toml
+[miruro]
+video_provider = ""
+caption_provider = ""
+```
+
+An empty or omitted preference means **Auto**. Automatic video selection prefers a usable **Sun** host, then the returned provider order. Automatic captions prefer the selected video's provider, then Sun, then the returned order. An unavailable or unsupported preference falls back to automatic selection; choosing captions does not change the video host. Provider names accept up to 128 ASCII letters, digits, underscores or hyphens; valid names need not be available for every episode. Unknown config keys and non-string values are rejected.
+
+Only native-playable sources are offered: iframe embeds and sources requiring a proxy or HLS rewriting are excluded. Provider selection does not switch into dubbed audio.

 - **Tubular:** catalog/detail browsing, actual returned episode selection, collections, private reporting sessions, cleanup and watched-state decisions.
 - **Terebi:** episode-URL validation, fresh source resolution, headers/subtitles, titles, optional timeline bands, stable-identity resume and progress reporting.
 
-Native source resolution selects direct **`ssub` / `sun`**. Other providers, iframe embedding, cookies, impersonation and protection-bypass machinery are not supported.
+Native source resolution discovers validated direct Japanese `ssub`/`sub` providers at runtime, preferring soft subtitles per provider. **Playback → Miruro** and the gear menu offer independent **Video Host** / **Caption Provider** choices; optional `[miruro]` config strings `video_provider` and `caption_provider` set startup preferences (empty means Automatic). Missing/unsupported preferences fall back to Sun then returned order for video; captions prefer the chosen video's provider, then Sun and returned order. Dub is not an automatic fallback. Iframe/proxy/HLS-rewriting providers, cookies, impersonation and protection-bypass machinery remain unsupported.
+Host changes resolve fresh sources and preserve acknowledged position and playing/paused intent; caption changes retain their own provider/server headers and do not reopen video. Caption language is retained when available, and explicit Off survives provider changes. Choices made in menus are session-only. Native source menus are disabled during opening, pending seeks and casting.
+
+Provider-selection verification: resolver, configuration, CLI and metadata checks passed; app/CLI builds passed. Local native HLS/VTT playback exercised independent caption headers, in-place caption changes, missing-host fallback, paused/playing host changes, failed-fetch retention and rejection of late results after close. Existing mixed queues, report isolation and subtitle timing checks passed. A live probe found only Sun as a supported native video/caption provider for the sampled episode, with nine VTT tracks; other providers' live playback and visible menu/subtitle verification are not claimed.
