Keep a TSV decision log for consequential choices, not a transcript of routine commands.
Use this header:
ts\tphase\tdecision\twhy\tevidence\tresult
Record a row when choosing between real alternatives, changing course after evidence, accepting or rejecting delegated work, crossing a phase boundary, or deciding that verification is sufficient. Use scripts/log.ps1 on Windows or scripts/log.sh in a POSIX shell.
Keep evidence as a stable file, line, commit, command result, metric, or URL. Sanitize tabs and newlines. Prefix spreadsheet-formula characters so untrusted evidence cannot execute when the TSV opens.
Before handoff, compare the log with the current task's actual tool results and repository state. Correct stale rows. Report the log path and whether it is intentionally local or part of the requested deliverable. Do not commit it unless the user or repository workflow wants an auditable trail in version control.
