fix(lg): decode the base64+zlib schedulelist payload - #64
Merged
Conversation
LG now serves the catalog as base64 of a zlib stream under text/plain, so res.json() threw and every sync fell back to the offline snapshot. That fallback skips both channel pruning and the self-EPG (syncLive gates each on result.live), so the LG guide had gone unwritten since ~2026-06-27. parseSchedulelist sniffs JSON vs base64+zlib/gzip, so an LG rollback needs no code change; inflate is bounded by a 64MB guard. Both callers (listChannels and syncLgEpg) share the one fetch point, so this covers each. Also: a missing EPG crosswalk addon (ENOENT) now logs at info rather than warn — it's the documented steady state for the 13 sources whose addon is wired but uncommitted, and the warning was burying real ones. A present-but-corrupt file still warns. Snapshot rebuilt live: 200 -> 194 rows (17 gone, 11 new).
