Criteria at decision time2 historical snapshots
v1 · applied at decision time
Explain how the option advances the project’s stated goal using the owner’s current preferences and the actual responsibilities involved. Treat job titles, employer prestige, and tool matches as context rather than automatic inclusion or exclusion rules. Identify meaningful tradeoffs in words.
Draft guidance · simulated trial
When proposing a week, preserve the owner’s protected focus and recovery blocks. If commitments conflict, describe the tradeoff and ask before moving a protected block. Explore whether time-sensitive opportunities justify an exception.
