These fixtures were derived from real sessions supplied by the PR author:
- Pi: Niulai session
01a0fce1-4bdb-7357-909d-1fc983a98dad(56 records). - Codex: deer session
01a0fce4-eacb-7890-b42c-f140d51b593d(43 records).
Record order, event types, timestamps, token counts and timing fields are retained. Event, response, process and tool-call IDs are consistently replaced with anonymous IDs, preserving their relationships. Only the two session IDs above remain as fixture labels.
Prompts, replies, reasoning, tool arguments/results, command output, paths, model/provider configuration and unknown fields are replaced with placeholders. Account/user identifiers, instructions, signatures, encrypted reasoning, environment/permission configuration, tool definitions, headers and URLs are removed. Remaining string values were checked against an explicit allowlist.
These are sanitized real transcripts, not synthetic event sequences. Pi and Codex have been tested end to end. Claude Code/Cowork, Oh My Pi, OpenCode and Gemini CLI have format tests but are not tested end to end by the PR author.
