Corrects the cause recorded an hour ago. responseGrammar ends with
ws ::= [ \t\n]*, and * is unbounded, so the model emits { and then satisfies
ws with whitespace until max_tokens stops it.
Reproduced on a second Qwen3-1.7B with the same grammar and system prompt:
repeat_penalty 1.0 runs to 512 and returns finish_reason=length, 1.3 stops at
24, and bounding the rule to {0,4} stops at 33 three times out of three with
no penalty at all.
internal/llm.Req sends repeat_penalty and the replier sets 1.3, so that path
is protected by accident. chatReq in the phraser sends none, so PhraseChat,
PhraseQuery, PhraseNudge and PhraseReminder run at the default 1.0.
Two wrong guesses recorded so nobody repeats them: not reasoning tokens, the
probe returned reasoning_content of length 0; and not --cache-ram 512, which
is MiB of prompt cache against a token count.
