[Bug] Claude Code ignores explicit CLAUDE.md instructions with helpfulness judgment calls

Bug Description
Title: Claude Code ignores explicit CLAUDE.md instructions by making "helpfulness" judgment calls

Environment: Claude Code CLI, Opus 4.5

Issue:
Despite explicit instructions in CLAUDE.md stating:

• "DO NOT start writing code until you have a sprint document"
• "EVERY feature gets a sprint doc"
• "No exceptions"

Claude still makes judgment calls like "this is only 7 lines, I'll skip the sprint doc" and proceeds to write code without following the documented process.

This happens repeatedly even after:

1. Adding stronger language ("NO EXCEPTIONS")
2. Adding explicit "NO JUDGMENT CALLS" sections
3. Restarting sessions to reload instructions

Expected: Claude follows explicit instructions without evaluating whether they "should" apply
Actual: Claude makes helpfulness-based judgment calls that override explicit rules

This undermines trust in the instruction system. If rules can be silently ignored based on Claude's assessment of "trivial", the entire CLAUDE.md system is unreliable.
