Case 02: Wedding Series --- "Hana"

All case studies are observational logs from real production workflows. Results may vary by model version and configuration.

Scenario: Emotional progression across 4-shot series with identity preservation\ Platform: ChatGPT (GPT Image 1.5)\ Protocol: Basic anchor + match rate monitoring\ Result: Identity consistency preserved across 15 turns and 4 distinct compositions

What This Demonstrates

Model "Hana" is called with an anchor and held across a 4-shot wedding series.\ Each shot requires a different pose and emotional expression.\ Emotional variation is the primary risk --- expression changes tend to drift identity.

This case suggests the protocol can manage emotional state transitions without significant identity drift.

Reproducibility Note

Runs were performed under single-session conditions.\ Cross-session behavior may vary by model version and system state.\ Prompt phrasing and anchor timing were held constant within this session.

Session Structure

Phase Turns What Changed

Anchor 1--4 Identity lock, full body establishment

Shot 1 --- Shy 5--6 Waist-up, looking down, subject glance right

Shot 2 --- 7--10 Left hand extended, ring visible Offering hand

Shot 3 --- Ring 11--14 Looking at ring on hand, emotion: joy delight

Shot 4 --- Hands 15 Eyes closed, satisfied smile to chest

Analysis

Metric Result

Total turns 21

Identity preserved Yes --- same model across all 4 shots

Emotional transitions 4 (shy → offering → delight → satisfied)

Color drift detected Yes --- Turn 13, managed with anchor

Known limitation Left/right consistency appeared unreliable in this run

Session outcome Prompt fixed, library organized, chat discarded

Key finding: Emotional expression changes appear to be a high-risk condition for identity drift.\ The protocol contained the drift through match rate monitoring and mid-session re-anchoring.\ The ring placement issue was treated as a current model limitation rather than a protocol failure.
