[Bug] Error handling ignores CLAUDE.md directives, adds unsafe fallbacks instead of returning errors

Question

**Bug Description**
Claude Code adds non-sensical fallbacks and swallows errors very frequently even having CLAUDE.md explicitly forbidding this behaviour and asking for error returns.

For example, just now Claude Code tried to handle an encryption fail by trying to send the data PLAINTEXT.

My work process is:

1. plan
2. implement
3. review until OK

However, I'm basically stuck in the review phase because I'm cleaning up millions of wrong fallback code lines.
