Observed adoption & comparisons
Source votes: 9 votes (Nov 14, 2026 UTC; cumulative since publication); previous same-scope observation: 8 (Nov 13, 2026 UTC). These observations do not establish demand growth. Recent records to compare: “alibaba/open-code-review” (GitHub Trending, Nov 14, 2026); “backnotprop/plannotator” (GitHub Trending, Nov 14, 2026). Shared themes are navigation hints; they have not been verified as the same need or independent corroboration.
Adoption decision
Evaluate it against the tool or manual workflow it would replace. The stored record supports discovery; it does not yet establish reliability, lower operating cost or commercial adoption.
Unverified requirements
Not verified: license permissions, required hardware, installation steps, maintenance status and a representative task with its failure cases.
Next test
Choose one real task and a current alternative. Record the commit, environment, input, output, elapsed time and failure behavior; retain the result before recommending adoption.
