Reviewed diff chunks: 2
Advisory LLM verdict: APPROVE
Advisory summary: Reviewed all 2 diff chunk(s). Chunk 1 of 2 covers ticket-055 governance scaffolding (README, intent., preprompt, changelog, logs, TICKETS.md/TODO/CHANGELOG updates) plus a mypy-type-annotation fix in data2dsl_adapters.py and the beginning of the generate-query CLI subcommand parser. Governance metadata is internally consistent (allowedPaths matches changed source files), tests reported passing (governance check PASS), and no security issues are visible. The implementation code (generator, CLI handler, tests) is in chunk 2 and cannot be assessed here. | Chunk adds a query template generator and CLI subcommand with tests. Logic is straightforward, tests cover integer/percentage/string-set paths and CLI output. Only one test check reported and it passes.
Advisory findings: none
The LLM output above is advisory and was not used as the approval trust root.
