[MODEL] Claude overwrites explicit user requirements with assumptions during documentation

Preflight Checklist

• [x] I have searched existing issues for similar behavior reports
• [x] This report does NOT contain sensitive information (API keys, passwords, etc.)

Type of Behavior Issue

Claude ignored my instructions or configuration

What You Asked Claude to Do

Document technology decisions for a project after discussing them. Specifically, I stated Square was my primary
payment processor (the service I personally use) and my first priority. Claude understood and suggested adding
Stripe as a secondary option. I agreed to Square + Stripe for v1.0, with PayPal for v1.1.

What Claude Actually Did

Created documentation stating "Stripe (primary) + PayPal (secondary)" - completely omitting Square despite it
being my explicitly stated #1 requirement that Claude actively participated in discussing and refining.

Expected Behavior

Documentation should reflect the actual decisions discussed, not assumptions based on "industry standards." When a user explicitly states a requirement and Claude participates in refining it, the recorded output should match
what was agreed upon.
