Digest a repo's recent activity the way a cortex consolidates memory — not a flat commit count, but 3 cortical layers (L1 Surface = what changed per day, L2 Association = braid commits+PRs+issues on one timestamp axis to expose issue→close latency, L3 Consolidation = rank days by MEMORY WEIGHT where feat/fix that lands weighs heavy, bump/chore decays, reverts are negative "forgetting"). Surfaces the "quality day" (high weight-per-commit) that a raw count hides, plots a forgetting curve (signal vs noise vs revert), and lists retained-memory highlights. Reruns on any repo via digest.sh (portable awk, macOS+Linux). Use to understand "what upstream actually RETAINED lately" in 30 seconds — not just "how many commits."
