The grammar examples in chatSystemPrompt were full clauses — ("я подумала",
"я рада") for her, ("ты сказал", "ты забыл") for him. A 1.7B copies those
instead of generalising from them.
Observed on homesrv 2026-08-01, in one session: all three chat replies
opened with "Я подумала, что ...", and one ended "...немного тревожусь.
ты сказал" — the second example pasted onto a finished sentence, which
reads as a truncation and is not one.
Contrastive pairs replace the openers, so the rule reads as a correction
rather than a template. The him-examples are dropped; the "ты" instruction
carries that on its own, and those two produced the worst output. A closing
line tells her not to echo the instructions, because a small model treats a
quoted string as licence to reuse it.
Verified after rebuild: three chat turns, no "Я подумала" opener, no
dangling example, feminine forms intact.
