# comeback.sh — "what did I miss?" sit-rep generator.
#
# Per HQ-Vault/_System/CLAUDE.md "The comeback protocol", reads the last 14
# days of dailies, every project _Log.md, and recent _AgentLog/ entries.
# Dumps them grouped + a per-agent activity tally so Rocky can scan in
# 30 seconds instead of opening 8 files in Obsidian.
#
# Usage:
#   bash scripts/comeback.sh             # last 14 days
#   bash scripts/comeback.sh 7           # last 7 days
#   bash scripts/comeback.sh 30 > sitrep.md   # 30 days, write to file
