# SessionStart hook (plan 2026-05-13, V1.0 task 1.C.3 + V1.1 task 2.C.2).
#
# At session start:
#   1. If .quellis/config.toml is absent, emit nothing and exit 0.
#   2. Otherwise, delegate to hooks/lib/sessionstart_inject.py which
#      reads intensity + scans recent git activity + injects matched
#      doctrine cards (max 5 cards, ~1500 tokens budget enforced in
#      hooks/lib/doctrine_loader.py).
#
# Real wiring contract:
#   - Hook receives no stdin input (per Claude Code's SessionStart contract).
#   - cwd is the user's repo root at session start.
#   - Anything written to stdout becomes session context.
#   - Exit 0 always; this hook must never break a session.
