Soft primitive — pure ratio over G.0 lexical counters: * positive — positive_lex_hits > negative + obscenity, ≥ VALENCE_MIN_HITS * negative — (negative + obscenity) > positive, sum ≥ VALENCE_MIN_HITS * neutral — fall-through Skip below VALENCE_MIN_TYPED_CHARS (80). Confidence hard-capped at EMOTIONAL_VALENCE_CONFIDENCE_CAP (0.5) inside the feature function; 0.30 below VALENCE_FULL_CONFIDENCE_MIN (200). Cap is registry convention.

All four primitives in this module ride a hard 0.5 confidence cap

|
(:data:`EMOTIONAL_VALENCE_CONFIDENCE_CAP`). Cap is enforced inside
|
|
the feature functions, *not* via :func:`make_observation` — sample-size
|
|
honesty may still pull confidence below 0.5.

|
Step G.5: ``emotional_valence.valence``.

Step G.6: ``emotional_valence.arousal`` (lands later).
|
|
Step G.7: ``emotional_valence.stress_response`` (lands later).

Step G.8: ``emotional_valence.frustration_venting`` (lands later).
