- four forks settled with KISS defaults grounded in runtime/src: counters+gauges only (profiling split out), Prometheus text rendered in .wo from a map<Text, Int>, pull via proc.metrics(), stack trace on trap lands first
- phases A (trace on trap at both trap sites) / B (proc.metrics from existing gc/arena/fiber fields) / C (porch mounts /metrics — consumer's phase)
- builtin id to be confirmed against WO_B_MAX at build time (random_bytes claims 119 per porch 2's brief)
- review_pending marker: forks auto-approved 2026-09-09, developer second review before code lands
- board row: refine -> ready
