# 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
