Archive Mode

If the user's task starts with `archive` (case-insensitive), do NOT run the pipeline. Instead, archive a completed contract.

If a contract ID is provided (e.g., `archive sig-20260314-1030-a1b2`), extract it from the user input. Otherwise, the active contract will be used.

Before running the Bash tool, parse the contract ID from the user's arguments (everything after `archive `). Pass it as `CONTRACT_ID_FROM_ARGS` environment variable. Use the Bash tool:

source lib/contract-dir.sh

# CONTRACT_ID_FROM_ARGS is set by the orchestrator from user input (may be empty)
CONTRACT_ID="${CONTRACT_ID_FROM_ARGS:-$(get_active_contract)}"
if [ -z "$CONTRACT_ID" ]; then
  echo "ERROR: No contract ID provided and no active contract found" >&2
  exit 1
fi

WAS_ACTIVE=false
if [ "$(get_active_contract 2>/dev/null || true)" = "$CONTRACT_ID" ]; then
  WAS_ACTIVE=true
fi

DIR=$(contract_dir "$CONTRACT_ID")
if [ ! -d "$DIR" ]; then
  echo "ERROR: Contract directory not found: $DIR" >&2
  exit 1
fi
