# RetrieX Follow-up Precision Fix

This patch tightens direct numeric follow-up handling without changing retrieval, scoring, shop, vector or database logic.

## Why

The follow-up query `mit welchem indikator wird der wert gemessen` could be treated too weakly as a technical product/value question because only `indikator` was a strong keyword. As a result, the stricter technical follow-up prompt rules were not always applied.

## Changes

- Adds `gemessen` / `measured` as technical prompt keywords.
- Adds explicit prompt rules to answer direct indicator/value follow-ups with the exact mapping first.
- Tells the model not to expand into the full indicator table, measurement principle, applications or advisory notes unless explicitly requested.
- Adds `gemessen` to the regression/effective-config keyword check.

## Expected behavior

Question: `mit welchem indikator wird der wert gemessen` after the 0,02 °dH / Testomat 808 answer.

Expected answer starts like:

`Der Wert 0,02 °dH wird beim Testomat 808 mit Indikatortyp 300 gemessen.`

The full indicator table should only be shown when the user asks for all indicators or detailed device information.
