Summary

• Add the optional query parameter to ReadLiveLogsRequest. It is missing from Document the backtests/read/log endpoint #2686, which only documented it for backtest logs.
• Update the length description to say it counts the rows that match the query.
• Update the deploymentOffset description to say it counts all rows, even with a query.
• Add "query": None to the live logs request in the Read Live Algorithm example.
• Regenerate the Live Management > Read Live Algorithm > Logs pages.

Test plan

• Called /live/logs/read on a running live algorithm. Confirmed that query is optional (omitted, null, and "" return all lines), that the filter is case-insensitive, that startLine/endLine index the filtered lines, that length counts the matching lines, that it works with deploymentLogs, and that the 250-line limit still applies.
• Confirmed that deploymentOffset is unchanged by query (1756 with and without query: "order", while only 629 matching rows precede the deployment).
• Ran python code-generators/API-Reference-Code-Generator.py; only the live Logs pages changed.
• Check the rendered pages on the docs site.
