🔍 Triage Assessment

Request Overview

Field	Value
Type	Bug Report
Urgency	Medium
Affected Users	Users in the EU Payment Methods flow (small subset)

📊 RICE Score: 20 (rice:medium)

Factor	Value	Reasoning
Reach	40 users/qtr	Issue states a small subset (EU payment flow users), so estimated limited quarterly reach.
Impact	1.0	Preference reset creates recurring UX friction but does not block core payment completion.
Confidence	0.8	Report is well-structured with clear repro steps and success criteria, but exact user volume is estimated.
Effort	1.6 person-weeks	Likely requires persistence-path fix + flag-conditional flow checks + regression testing around auth/session states.
Score	20	(40 × 1.0 × 0.8) / 1.6 = 20

🎯 Kano Classification: Must-Be

For users, theme preference persistence is a baseline product expectation. Its absence causes dissatisfaction even if fixing it is not a "delight" feature.

🧭 Strategy Alignment

This request aligns with "Ship to learn, even over planning to be right" because fixing a concrete launch UX defect quickly supports learning in the EU rollout. It is otherwise neutral to the remaining tradeoffs.

🔄 Current Work Status

This is aligned with current work: the issue explicitly references launch #3 (EU Payment Methods), indicating overlap with an active launch area. Adding aligns-with-current is appropriate.

📋 Recommendation

Prioritize this as a near-term launch-quality bug fix in the EU Payment Methods stream. The score is medium because reach appears limited, but the issue affects a baseline UX expectation and can erode confidence in launch polish. Keep scope focused to persistence behavior under EU feature-flagged flows and verify with a regression test.
