# draft-response-storage.sh -- Draft CRUD, Storage, and Action Commands
# =============================================================================
# Provides the full draft lifecycle: create, read, list, show, approve, reject,
# status, and process-approved. Handles local file storage for draft body and
# metadata, and interaction with external GitHub items.
#
# Covered functions:
#   - Draft ID and file path helpers
#   - Draft body file write and metadata creation
#   - Draft finalization (notification issue creation + meta write)
#   - Item state loading from contribution-watch
#   - cmd_draft — create a new draft reply
#   - cmd_list  — list drafts by status
#   - cmd_show  — display draft content (with prompt-injection scan)
#   - _approve_post_comment, _approve_close_notification, cmd_approve
#   - cmd_reject  — discard a draft
#   - cmd_status  — summary of all drafts
#   - _process_approved_post_reply, cmd_process_approved
#
# Usage: source "${SCRIPT_DIR}/draft-response-storage.sh"
#
# Dependencies:
#   - draft-response-notification.sh (loaded by orchestrator)
#   - shared-constants.sh (colors, print_error, etc.)
#   - shared-gh-wrappers.sh (gh_issue_comment, gh_pr_comment, etc.)
#   - gh CLI, jq
#
# Part of aidevops framework: https://aidevops.sh

# Apply strict mode only when executed directly (not when sourced)
