-- Archive flag for healthchecks the technician no longer needs surfaced.

-- Boolean stored as INTEGER 0/1 (portable: MySQL has no native BOOLEAN, it's a
-- TINYINT alias, and SQLite has no boolean type at all — both store 0/1 in an
-- INTEGER column). NOT NULL DEFAULT 0 so every existing row is "not archived"
-- and SQLite's ALTER TABLE ADD COLUMN is satisfied (it requires a default for a
-- NOT NULL column).

-- Archived rows are NOT hidden from their normal listings for now; the dashboard
-- just additionally gathers them under an "Archived" heading on the home page.

ALTER TABLE healthchecks ADD COLUMN archived INTEGER NOT NULL DEFAULT 0;
