The switch: stop writing Session logs #997

Parent

#700

What to build

Session traces take over from Session logs.

• Sessions stop writing the raw Session log. A session writes its Session trace, Model evidence and review reports. The Command record names the log records' file.
• The old readers go: the Waterfall's Command-log matcher, and every reader of the old Session-log format. Both hosts' logs were converted in Convert both hosts' Session logs and check the reports #994.
• The words change: GLOSSARY.md renames Session log to Session trace and adds Trace, as ADR 0019 says. The guide, the README and the Session prompts follow, with the prompts page regenerated.

Acceptance criteria

• A session writes only its Session trace, Model evidence and review reports.
• No code reads the old Session-log format, and the Command-log matcher is gone.
• The glossary has Session trace (Avoid: Session log) and Trace, the docs and Session prompts match, and the prompts page's check passes.
• Tests run on Session-trace fixtures only.
