The generator gated all union decoder emission behind knownDiscriminators, a hand-curated map of 13 entries. Any sealed union absent from that map received no decoder, so decoding must fail. Bot API v10 added RichBlock and RichText, which were absent. Roughly 8.6 percent of Telegram updates failed with HTTP 400. The generator now derives discriminators from the specification instead of a fixed list. A gate check fails the build when a union resolves no discriminator. Eleven unions gain decoders that never had one: BotCommandScope, InputMedia, InputPaidMedia, InputPollMedia, InputPollOptionMedia, InputProfilePhoto, InputRichBlock, InputStoryContent, PassportElementError, RichBlock and RichText. RichText can also appear as a bare string or an array of RichText. The scraper now extracts these alternate shapes into the intermediate representation. The emitter adds RichTextPlain and RichTextSequence. The decoder dispatches on the first JSON byte before it reads any discriminator. Unions without alternates must regenerate byte for byte. The golden test proves this. Claude-Session: https://claude.ai/code/session_01Fu2wXqGUrfVBi5aLafKk8U
