Operator Intelligence Shorthand (FDE)
Adapted from Chrysalis Intelligence Shorthand (IS-T5…T0): store verified procedures and oracles, not neural weights. Models may propose narration; goldens / CLI / certificates dispose. LLM output never enters World.step.
Tier ladder
| Tier | FDE meaning | LLM? |
|---|---|---|
| IS-T5 | Frozen golden / certificate | No |
| IS-T4 | Deterministic CLI / script recipe | No |
| IS-T3 | Skill capsule (verify-gated digest) | No on hit |
| IS-T2 | Domain adapter (reserved) | — |
| IS-T1 | Prompt pack / optional prose over frozen JSON | Yes, post-hoc only |
| IS-T0 | General model (last resort) | Yes, never in-sim |
Selection rule: prefer the lowest tier that covers the task.
CLI
```bash
fragility shorthand list
fragility shorthand resolve validate-benchmarks
fragility shorthand resolve llm-prompt-bundle
fragility shorthand export --out artifacts/operator_shorthand/fde-shorthands.v1.json
```
Package
fragility_engine.shorthand — capsules registry + resolve_task.
Provenance note in export JSON credits Chrysalis IS design; this is a thin Python port of the protocol, not a dependency on @chrysalis/web-llm.
