 | Missing exact benchmark implementation and regression fixtures | Without exact values, the package cannot serve as a reproducible QET benchmark. | Closed | Core software | Implemented exact Hamiltonian, ground state, QET ledger, benchmark CSV, figures, and regression tests. | `v0.1.0` |
 | No explicit no-free-energy accounting guardrail | QET is easy to overstate if Alice injection and global accounting are omitted. | Closed | Scientific framing | README, docs, tests, and paper state that Bob extraction is paid for by Alice measurement/control resources and check `E_A >= E_B` for the exact benchmark. | `v0.1.0` |
 | Missing artifact provenance | Reviewers need to know which script generated each CSV/figure and what each artifact validates. | Closed | Reproducibility | Added artifact manifest mapping outputs to generators, validation coverage, and supported claims. | `v0.1.0` |
-| Hosted CI unavailable because of quota | Hosted CI gives reviewers an independent, visible validation path; local-only validation is weaker. | Closed | Review infrastructure | Repository visibility was changed to public and GitHub Actions passed on Python 3.11 and 3.12. | hosted run <https://github.com/lucent-lab/qet-bench/actions/runs/24507308274> |

 | Placeholder software citation metadata | Citation metadata must identify a real citable artifact and author record. | Mitigated | Publication metadata | Replaced placeholder contributor author with provisional author metadata and added preferred software citation fields. Add DOI once archived. | `v0.2.0-paper-review` |
 | Manuscript venue ambiguity | Trying to satisfy JOSS, ReScience, and SoftwareX simultaneously weakens the paper. | Mitigated | Manuscript | Reframed `paper.md` as JOSS-style source and moved ReScience/SoftwareX notes to build/readiness documentation. | `v0.2.0-paper-review` |
