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-001 — Semantic Action Stability
## Claim
A semantic action survives implementation restructuring better than a recorded UI
interaction sequence.
## Falsification condition
Across the labelled mechanical mutations in the lab (T05), a recorded interaction
sequence survives **at least as many** mutations as the semantic action does.
If mechanics-free identity buys no measurable durability, the central abstraction
is decorative and `SemanticAction` should be reduced to a naming convention.
## Measurement
Mechanical Recovery Rate for each of two arms over the same mutation set:
- **arm A** — semantic action realized by an agentic driver;
- **arm B** — a recorded selector-based sequence captured against the baseline.
Arm B is a genuine control and must be run, not assumed to fail.
## Threats to validity
The comparison is unfair if arm B is built naively — a brittle straw man makes
H-001 trivially true and worthless. Arm B uses the most robust selector strategy
reasonably available (roles, labels, test ids where the lab provides them).
## Status log
- 2026-08-22 `PROPOSED`. No evidence.
