Make Claude Opus 4.8 behave like the suspended Claude Fable 5 in Claude Code: a behavioral governor, a re-injection hook, and a leak-test harness measured from real logs.

| Usefulness | 2/5 |

## Verdict

A behavioral patch to make Opus 4.8 impersonate a suspended model is a curiosity at best — the gap between prompt injection and actual Fable 5 behavior is unbridgeable, and the value proposition evaporates the moment Fable 5 resumes or Opus diverges further. Zero stars, no community, no topics, and a premise that ages poorly make breakout essentially impossible.
