Mutation check done on all accepted tasks; mutant fixes; dump filter in proxy

- skip sy-subrc lines and CDS type lengths; CDS literal mutants; mutate helper classes
- proxy: sap_short_dumps shows only dumps of the current run
- 26/26 tasks pass; results in docs/faz1-tasarim.md 11g

 - Generator: static checks, local abaplint parser check, dependency order of seed/reference, budget floor,
   max_tokens 80k. Runner: G2 for CDS with parameters, G6 ignores unknown standard superclasses.
-- Step D: `harness/mutation.py` (deterministic mutants of the reference, hidden tests must fail).
+- Step D done: `harness/mutation.py`, part of generator acceptance. All 26 tasks pass (`docs/faz1-tasarim.md` 11g).
+  Killed mutants are kept in `<task>/faulty/`.
+- Step 5 code: H stop scoring (`judge.py`), K variants (`make_k_variant`), proxy tool schema `generic_v0` (draft).
+  Not yet run on SAP.
+- Step F: `harness/evalset.py` (88 slots G0100–G0187). Not started.
 
 ## 7. Next steps
 
-1. Step D: run the mutation check on all accepted tasks; integrate it into the generator.
-2. Use killed mutants as faulty references for own-test scoring (component (a)).
+1. Test one H slot (G0168) and one K slot (G0178); then run step F (`python3 -m harness.evalset run`).
+2. Own-test scoring part (a): run the model's own tests against `faulty/` mutants.
 3. Step F: eval set of 110 tasks: ~150 candidates, empirical filter (2–3 models), Claude review with a
    checklist, Kral spot-checks ~10 flagged tasks.
 4. Scoring for stop tasks (category H) and category K (free-text input, other tool schema).
