Claude's safeguards poison entire chat over benign request; user had to surgically edit MEMORY.md to revive it

User greghunkin reports Opus 5.5 safeguard changes: three unrelated refusals in one day. Asking Claude to summarize a YouTube video that mentioned sidestepping a model's IP filters triggered its safeguards, poisoned the whole chat and caused permanent refusals. Only by modifying MEMORY.md and excising the project memory file could he restore functionality — making him grateful for open models and competition. Shared with a "make the Chinese one do it (DeepSeek)" meme.
