"Closing ritual for the AI-native estimation feedback loop. ALWAYS use when a ticket's PR has just merged (runs automatically per ticket: merge-pr step 12b / phase-monitor-merge, CTL-189/CTL-831), or when the user says 'compound-estimate', 'close the estimation loop', 'record actuals', 'compound-log', or wants to log post-merge actuals for a shipped Linear ticket. Writes a structured entry (linear.key, pr_number, merged_at, estimate_at_start, estimate_actual, cost_usd, wall_time_hours, what_worked, what_surprised_me) to thoughts/shared/retros/estimate/YYYY-WW-compound-log.md — one file per ISO week, appends."
