Package authhdr parses client authentication headers without exposing tokens in URLs.

Package caps builds neutral client capabilities from protocol profiles.

Package clientnet classifies authenticated frontend peer and proxy addresses.

Package conformance reads release-generated, embedded protocol evidence.

Package faillog logs a repeating background failure (a heartbeat or sync loop that cannot reach the database) without flooding the log: the first failure is logged at WARN, later ones are summarised at most once per interval, and the recovery is logged once at INFO.

Package hls writes token-free playlists under random session paths.

Package ids provides stable, stateless protocol identifiers.

Package images contains protocol-independent artwork helpers.

Package language exposes the shared language-tag validation to frontends.

Package libpath defines the shared virtual library names exposed by clients.

Package listcache keeps whole-library listings encoded on disk, so a protocol whose clients download a library in one response (Xtream's get_vod_streams) streams a file instead of reading, authorizing, signing and encoding the library again.

Package lru provides a least-recently-used cache bounded by entry count and total cost.

Package mediasafety isolates untrusted media from the console origin.

Package paging applies bounded offset/limit windows without integer overflow.

Package quality exposes the transcoder's published H.264 rung targets without a frontend importing the transcoder.

Package reqmemo memoizes point reads for the length of one read request.

Package route provides an enumerable case-insensitive protocol router.

Package rows supplies helpers for rendering supported neutral row entries.

Package sort translates protocol sort keys into Ether browse orders.

Package support connects authenticated frontend requests to the owner's bounded diagnostics recorder.
