#$ARGUMENTS </execution_context>

Phase 1: Time Window

1. Determine retrospective window

   Parse arguments:

   • Default: last 7 days
   • --window Nd → N days back from today
   • --since YYYY-MM-DD → explicit start date

   # Calculate the since date
   if [ -n "$SINCE" ]; then
     since_date="$SINCE"
   elif [ -n "$WINDOW" ]; then
     days="${WINDOW%d}"
     since_date=$(date -v-${days}d +%Y-%m-%d 2>/dev/null || date -d "${days} days ago" +%Y-%m-%d)
   else
     since_date=$(date -v-7d +%Y-%m-%d 2>/dev/null || date -d "7 days ago" +%Y-%m-%d)
   fi
   until_date=$(date +%Y-%m-%d)
   

2. Load previous retro snapshot (for trend comparison)

   # Find the most recent previous retro
   ls -1 .lavra/retros/*.json 2>/dev/null | sort | tail -1
   

   If exists, load it. Enables velocity trend comparison and topic drift analysis in later phases.

Phase 2: Shipping Analysis

Analyze git history within window.

1. Identify current user

   git config user.email
   git config user.name
   

   Use to distinguish "You" from teammates in all output.

2. Commit breakdown

   git log --since="$since_date" --until="$until_date" --format="%H|%an|%ae|%s" --no-merges
   

   Compute:

   • Total commits by author
   • Type breakdown by conventional commit prefix (feat/fix/refactor/test/chore/docs)
   • Non-conventional commits → flagged "untyped"

3. Diff statistics

   git log --since="$since_date" --until="$until_date" --shortstat --no-merges --format=""
   

   Aggregate: files changed, lines added, lines removed.
