Design doc: new §4.6 post-mortem (quote char -> guided-decoding whitespace loop -> dead IMAP conn -> non-terminal mail), updated module inventory, vLLM/e-mail experience sections, test counts (51 -> 63) and the latency limitation (now bounded by max_tokens). User manual: version note + troubleshooting row for repeating alerts. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
