-- Migration 027: add soft-delete columns and update views
|

-- Adds deleted_at to languages, tags, theses so deletions are reversible.

-- Add soft-delete columns (idempotent: ALTER TABLE ... ADD COLUMN fails gracefully if column exists)
|

|
ALTER TABLE tags ADD COLUMN deleted_at TEXT DEFAULT NULL;
|
|
ALTER TABLE theses ADD COLUMN deleted_at TEXT DEFAULT NULL;

-- Rebuild views to filter out soft-deleted rows.
