A framework for the cost of inquiry across biological and synthetic systems. Renamed from IC|CS on 2026-05-18.
Ærr Frame names a recurring failure mode: systems accepting cheaper local substitutes for globally satisfying answers while their local checks stay green. It supplies three measurements of that failure — a floor (the cost any genuine answer must pay), a discipline (how often that floor is paid), and a drift (how fast surrogates accumulate when it isn't).
In lineage order:
| # | Title | Year | Path |
|---|---|---|---|
| 1 | The Interrogation Collapse | 2026 | papers/ic-cs/ |
| 2 | The Chaos Nexus of Self | 2026 | papers/ic-cs/ |
| 3 | The Ærr Trinity | 2026-05-27 | papers/aerr-trinity/ |
The IC|CS atom (papers 1 and 2) remains addressable under papers/ic-cs/. It is preserved as one atom under the new umbrella.
Constructive instances of the Surrogate Existence Postulate across behavioral, explanatory, and geometric substrates.
- Reward model overoptimization — behavioral substrate
- Unfaithful chain-of-thought — explanatory substrate
- Non-surjective activation steering — geometric substrate
Ærr Sensor — MCP server measuring κ, Ærr Rate, and Chain Drift on real systems. v0.1 ships the keystone formulae from the Trinity paper: measure_kappa, aerr_rate, chain_drift, compute_floor, convergence_watch.
