rule TemplateSave {
when: TemplateSaveRequested(template_id)
-- Liquid validation first (parse check for syntax errors)
-- If invalid: blocks save, shows error inline in editor
-- If valid: bumps version, saves to DB + rewrites .liquid file
-- See engine_side_effects.allium UpdateTemplateSideEffects
}
rule TemplateDelete {
when: TemplateDeleteRequested(template_id)
-- Checks for references: posts using this template, tags with postTemplateSlug
-- If references exist: native confirm dialog (rfd)
-- "This template is used by N posts and M tags. Force delete?"
-- Force delete: nulls templateSlug on referencing posts,
-- nulls postTemplateSlug on referencing tags
-- If no references: deletes without confirmation
-- Deletes DB record + .liquid file on disk
-- Closes template tab, sidebar removes item
