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.
