The library-PCA run produced otherwise-clean concept directions but
cozy/sensual → resigned/grief_stricken with cos ~0.7-0.8. Diagnosis:
all four stories genuinely share 'solitary woman at home, slowed
body, interior attention, domestic stillness' as their dominant
phenomenology. PCA correctly finds that cluster as THE concept
because no story in the corpus holds that setup constant while
varying valence — every 'slowed-body domestic' story happens to ALSO
be positive-valence (cozy/sensual) or negative-valence (resigned/
grief_stricken).
Adding paired variants that hold setup constant:
- sunday_afternoon/resigned.txt — same couch + blanket, inner state is
'Monday is going to bring bad news, this is the last Sunday like this'
- sunday_afternoon/grief_stricken.txt — same couch + blanket, inner
state is 'three weeks since mother died, cat she can't feel'
- waiting_for_results/at_ease.txt — same wait-for-call-setup as the
existing resigned variant, inner state is calm preparedness
Forces the next retrain to find the valence-within-cluster axis as
the emotion direction rather than the cluster-membership axis.

Three new paired scenarios targeting the concepts that came out
fragmented or collapsed in the L58-63 quality analysis:
- sunday_afternoon/ — same setup (couch, blanket, Sunday light),
three phenomenological framings for content/cozy/sensual. The
previous stories for these three differed in setting as well as
phenomenology, which let "comfortable body at home" dominate the
shared signal. Locking the setting forces the model to isolate
what each concept adds: life-rightness (content) vs. warm-shelter
(cozy) vs. sensory-aliveness (sensual).
- the_writing_session/ — essay drafting under deadline. in_flow /
anxious / stuck variants force the cognitive-state family apart
on the same cognitive task. in_flow specifically targets the
transparent-effort phenomenology (hands-followed, time dilation)
rather than the broader feel-good it was absorbing.
- the_morning_commute/ — anchors anxious to performance/work-anxiety
flavor, paired with calm. The 5 existing anxious stories were
phenomenologically diverse (performance, social, existential);
this adds a specific homogeneous instance to pull the centroid.
After retraining: expect first_pc_variance_ratio to rise for in_flow
and anxious, and nearest_concepts cosine to drop for content/cozy/sensual.
