behavior.\n\n## Non-goals\n- Do not re-open completed AB13HD/MB04HD/MB04CD smell and coverage tasks unless new evidence points to a fresh issue.\n- Do not use the stale

stale line-ratio concern with behavior coverage.\n\n## Context\n- Current `src/MB/mb01vd.c` implements sparse and dense branches with `DCOPY`, `DLASET`, and `DSCAL` helpers across `TRANA`/`TRANB` combinations.\n- The old audit described this as only a basic dense path, which is stale.\n\n## Acceptance Criteria\n- Add persistent tests or a Fortran differential that covers `NN`, `TN`, `NT`, and `TT` paths with both sparse and dense inputs where practical. Done.\n- Verify `MC`, `NC`, `INFO`, and `C` output parity. Done.\n- Keep the task scoped to MB01VD behavior; do not refactor the branch structure unless a mismatch is found. Done.\n\n## Validation Gates\n- `uv pip install .` passed.\n- `.venv/bin/pytest tests/python/test_mb01vd.py -q --override-ini addopts=` passed: 9 passed.\n\n## Completion Note\n- Added direct C-symbol tests via the installed `_slicot` extension for MB01VD, since this routine is not exposed as a public Python wrapper.\n- Covered `TRANA`/`TRANB` combinations `NN`, `TN`, `NT`, and `TT` for dense and sparse `A` inputs, comparing `C` against NumPy `kron(op(A), op(B))` with nontrivial `alpha` and `beta`.\n- Added alpha-zero coverage for the existing-output scaling path.\n- Committed as `49f5391`.\n\n","ts":"2026-05-10T01:25:07.128597Z"}} {"type":"state","ts":"2026-05-10T01:25:07.128597Z","data":{"id":"CHLHPT","state":"done","ts":"2026-05-10T01:25:07.128597Z"}} +{"type":"claim","ts":"2026-05-10T01:25:21.291704Z","data":{"id":"LZ6EVQ","agent_id":"gpt-5@Jamess-MacBook-Pro.local","ts":"2026-05-10T01:25:21.291704Z"}} +{"type":"state","ts":"2026-05-10T01:25:21.291704Z","data":{"id":"LZ6EVQ","state":"doing","ts":"2026-05-10T01:25:21.291704Z"}} +{"type":"result","ts":"2026-05-10T01:28:20.013055Z","data":{"task_id":"LZ6EVQ","summary":"Inline sort matched Fortran DLASRT;

currently relies on mathematical property tests only.\n- Prove selected generalized/closed-loop residual outputs match the pinned Fortran reference.\n\n## Context\n- Current evidence: `src/SG/sg02cw.c` is 1642 lines, among the largest translated routines with a Python wrapper and no differential test.\n- `tests/python/test_sg02cw.py` has broad property coverage for continuous/discrete, `JOBG`, generalized `E`, transpose, and triangle options, but previously had no `fortran_reference` or `run_fortran_driver` usage.\n- `SLICOT-Reference/src/SG02CW.f` is present.\n\n## Acceptance Criteria\n- Add a persistent SG02CW differential test using `tests/python/fortran_reference.py` against `SLICOT-Reference/src/SG02CW.f`. Done.\n- Cover at least one generalized `E` case (`JOBE != 'I'`) and one non-default option combination that is already represented in the Python tests, such as discrete time, `JOBG='D'`, `TRANS='T'`, or lower-triangle output. Done: generalized `E`, `JOBG='D'`, `JOB='N'`, `TRANS='T'`.\n- Compare `INFO`, residual `R`, closed-loop `C` when requested, and the `NORMS`/scale outputs returned by the wrapper. Done.\n- Keep the existing property tests as separate coverage; do not replace them with golden outputs only. Done.\n\n## Validation Gates\n- `uv pip install .` passed.\n- `.venv/bin/pytest tests/python/test_sg02cw.py -q --override-ini addopts=` passed: 19 passed.\n- Run the new SG02CW Fortran differential test directly: included in the targeted command above and passed.\n\n## Completion Note\n- Added `test_sg02cw_general_e_transpose_matches_fortran_reference` in commit `9f2cfa7`.\n- The new test compiles a Fortran driver via `tests/python/fortran_reference.py`, calls `SG02CW('C','N','G','M','D','U','T')`, and compares `R`, `C`, `NORMS`, and `INFO` against the Python wrapper.\n","ts":"2026-05-10T02:36:58.044198Z"}} {"type":"state","ts":"2026-05-10T02:36:58.044198Z","data":{"id":"5RD33X","state":"done","ts":"2026-05-10T02:36:58.044198Z"}} +{"type":"claim","ts":"2026-05-10T02:37:18.016306Z","data":{"id":"OWPEIO","agent_id":"codex","ts":"2026-05-10T02:37:18.016306Z"}} +{"type":"state","ts":"2026-05-10T02:37:18.016306Z","data":{"id":"OWPEIO","state":"doing","ts":"2026-05-10T02:37:18.016306Z"}} +{"type":"result","ts":"2026-05-10T02:40:22.8115Z","data":{"task_id":"OWPEIO","summary":"Added MB04HD Fortran differential coverage for COMPQ1/COMPQ2 identity transformations.","path":"tests/python/test_mb04hd.py","sha256_at_attach":"4c7e9524791d887550058194090b6207144947e314e408e8dd02a5f59233b3ff","mtime_at_attach":"2026-05-10T02:39:44.505585518Z","git_commit_at_attach":"4aca64dd744c6ba748332a1036d92ff0dfd1ac72","ts":"2026-05-10T02:40:22.8115Z"}} +{"type":"body","ts":"2026-05-10T02:40:22.813167Z","data":{"id":"OWPEIO","body":"Added a persistent Fortran differential test for MB04HD with COMPQ1='I' and COMPQ2='I'.

translated routines","body":"## Scope\n- Add Fortran differential coverage for the currently highest-risk translated routines that already have Python tests but no `run_fortran_driver` comparison.\n- Use the fresh 2026-05-09 scan of `python/slicot_module.c`, `src/**`, and `tests/python` as the starting point.\n\n## Ranking Evidence\n- Existing active ergo backlog was empty before this plan: `ergo --json list` returned `[]`.\n- Current Fortran differential coverage found 25 wrapped routines with `run_fortran_driver` references.\n- Top missing-risk routines by local heuristic were: `mb03id` (score 12584), `mb04qc` (12350), `mb03jd` (9590), `mb03jp` (9207), `sb10zd` (8511), `mb04ad` (7352), `sb10dd` (7316), `mb03ke` (7305), `tg01jy` (6246), `ab09jd` (5928), `mb04ed` (5760), `sb10kd` (5552).\n- Example drivers exist in `SLICOT-Reference/examples` for `sb10zd`, `mb04ad`, `sb10dd`, `tg01jy`, `ab09jd`, `mb04ed`, and `sb10kd`; the top MB03/MB04 routines need synthetic/doc-derived drivers.\n\n## Non-goals\n- Do not try to cover every translated routine in one batch.\n- Do not overcompare undefined workspace or off-contract matrix regions.\n- Do not introduce standalone planning markdown; keep decisions in ergo and tests/scripts.\n\n## Validation Pattern\n- Rebuild first with `uv pip install .`.\n- Run the targeted pytest for each routine.\n- Run `scripts/check_translation_smells.py` after any C fix.\n- Use `scripts/check_translation_coverage.py` when a differential exists to protect a risky branch/line.\n- Run `.venv/bin/pytest tests/python/
