The `logs` subcommand's reporting -- show_logs() and summarise() -- is read-only analysis of the JSONL session logs and shares nothing with the scrape/review flow, so it moves to _logs_report.py. cli.py re-exports both through __all__ so cli.show_logs / cli.summarise stay valid for test_cli.py and the dispatch table. The PEP 484 `X as X` alias form does NOT survive here: ruff flags it PLC0414, autofixes it away, and then deletes the import as unused under F401 -- which would break cli.summarise with lint still green. Recorded in the handoff so it is not re-derived. cli.py 282 -> 247, new _logs_report.py 76. 277 wsg_grabber tests pass.
