Git Context Controller (GCC) v2

Overview

GCC transforms agent memory from verbose markdown into a lean, git-backed index. Instead of duplicating what git already knows, GCC stores only hash + intent + optional decision notes (~50 tokens vs ~500 per entry). Full context is reconstructed on demand via git show.

Two modes:

• git mode: Real commits, lean index.yaml, worktree isolation, aiyoucli bridge
• standalone mode: Markdown fallback for projects without git (v1 compatible)

Initialization

On first use, check if .GCC/ exists. If not, run the init script:

scripts/gcc_init.sh          # auto-detects git/standalone
scripts/gcc_init.sh --upgrade # migrate v1 → v2
