Status: SYNTHETIC DEMO · PRE-IMPLEMENTATION

A. QUESTION

Do I like this song?

The system should refuse the implication that there must be one timeless Boolean.

Use a synthetic musical work:

WORK:
"Northbound Lights"

No copyrighted audio is required for the proving fixture.

C. TRAJECTORY

dislike
→ familiarity
→ appreciation
→ love
→ saturation
→ avoidance
→ dormancy
→ nostalgia
→ affectionate return

This is not a contradiction sequence.

It is the relation history.

D. WHAT STATIC PERSONALIZATION GETS WRONG

After encounter #1:

user dislikes song

After #8:

user dislikes song

Both lose the meaningful trajectory.

Better:

first-listen negative
slow acquisition
high peak
saturation
long dormancy
nostalgic return

E. REVISITABILITY

At #8 the current response is strongly negative.

Should the agent permanently suppress the work?

No automatic inference.

Possible reopening evidence:

negative response follows heavy saturation
historical peak was high
long gap may alter response

Derived candidate:

revisitability = plausible_after_dormancy

Not:

force replay

F. PERSONAL CONCEPTS

After many works, Amnesiac may discover:

slow_burn_music
overplay_sensitive
night_drive_context
nostalgia_return

Only if supported by repeated trajectories.
