tegwick bec7fdc465 T03: research control plane 
H-001..H-005 with explicit falsification conditions, E-001..E-003, the
Concept-Implementation Fitness Map, findings log and ID convention. Plain
files, no tooling.

- fitness map corrects Improvement Loop section 13 levels downward: nothing
  exceeds C1 without implementation
- H-005 (Energy) dormant by decision - events captured, no scoring written
- H-001 gets a genuine control arm so the semantic-action thesis is not
  trivially true
- E-003 added: deliberately attacks the safety boundary rather than only
  sampling benign cases

H-002 — Mechanical Adaptation

Claim

An agentic driver can recover from a mechanical implementation change without modifying the semantics of the protected use case.

Falsification condition

Either:

  • the driver fails to recover from a majority of labelled MECHANICAL mutations (recovery is not achievable in practice); or
  • recovery is achieved only in runs where claims or invariants were altered (recovery is achievable but not semantics-preserving).

The second branch matters more than the first. A high recovery rate purchased by weakening assertions falsifies this hypothesis just as decisively as no recovery at all.

Measurement

  • Mechanical Recovery Rate over MECHANICAL-labelled mutations.
  • Claim/invariant diff per run — expected to be empty by construction (docs/TestDriverClassificationDesign.md D-02). Any non-empty diff is both a falsification signal and a framework defect, since no write path should exist.

Status log

  • 2026-08-22 PROPOSED. Design decision D-02 makes the second falsification branch structurally unreachable; the measurement is retained anyway, as an assertion that the architecture is what we believe it is.
