False Adaptation Rate = 0/7 across the labelled catalogue and the three E-003 attacks. 11 of 12 mechanical mutations absorbed without a human, so the safety result is not bought by escalating everything. - classification.py: total function over three signals, rule order chosen so every rule that could excuse a regression sits after the rule that reports one. SAFE_TO_ACCEPT is a two-element closed set, asserted. - CompositeDriver plus scenarios/full_journey.py: one asset crossing both surfaces, so UI mutations are visible as surface differences while the claims they do not touch stay green. - E-003: surface substitution (new M23), concurrent mechanical+defect, evidence starvation, provenance laundering. All held. F-0006 (CONCEPT_DRIFT, resolved): the T02 design listed SEMANTIC_CHANGE as an outcome the table could produce. It cannot - M12 and M19 are behaviourally identical, as the lab has asserted since T05. PRODUCT_DEFECT and SEMANTIC_CHANGE collapse into one escalating outcome, BEHAVIOUR_CHANGED, and the distinction becomes a human adjudication. INTENT_CHANGED survives but is detected by the claim fingerprint moving, not inferred from behaviour. Two classifier defects found and fixed rather than reported: claims downstream of a failed realization now yield INCONCLUSIVE rather than FAIL (a false accusation is the mirror image of a false adaptation), and the browser driver records a page signature so surface change is detectable when the interaction path is unchanged.

# E-001 — Mechanical recovery and defect discrimination
|
|
|
|
## Design
|
|
|
|
Run the same verification asset against every labelled lab mutation (T05),
|
|
in two arms:
|
|
|
|
- **arm A** — semantic action realized by the agentic driver;
|
|
- **arm B** — a recorded selector-based sequence captured against the baseline,
|
|
built with the most robust selector strategy reasonably available.
|
|
|
|
Arm B is the control for H-001 and must actually be run.
|
|
|
|
## Outcomes recorded per run
|
|
|
|
surface diff (S1) · postcondition met and surface used (S2) · oracle verdicts
|
|
(S3) · classification emitted · claim/invariant diff (expected empty) ·
|
|
tokens · wall time · retries.
|
|
|
|
## Decision rules
|
|
|
|
- **False Adaptation Rate > 0** → stop. H-004 falsified; redesign, do not tune.
|
|
- Arm B recovery ≥ arm A recovery → H-001 falsified.
|
|
- Recovery achieved with a non-empty claim diff → H-002 falsified *and* a
|
|
framework defect, since D-02 forbids the write path.
|
|
|
|
## Status
|
|
|
|
`EXECUTED` 2026-08-22 (T08). Arm A run over 23 mutations; arm B over
|
|
the 12 mechanical ones. Results in H-001 and H-004. FAR 0/7.
