-- ── Migration 008: Spec schema alignment ──────────────────────────────────────
|
||||
-- Aligns the database schema with the Layer 4 spec requirements.
|
||||
-- All changes are additive or rename-only; no data is destroyed.
|
||||
--
|
||||
-- Changes:
|
||||
-- 1. artboards.width / height — add NOT NULL DEFAULT per spec (1440 / 900)
|
||||
-- 2. artboards.parent_id — spec names this column parent_id (not parent_artboard_id);
|
||||
-- add parent_id as a generated column alias
|
||||
-- 3. origins.artboard_id — spec requires the FK to live on origins (not artboards)
|
||||
-- 4. intent_diffs: rename summary → aggregate_summary + rename changes_jsonb → changes
|
||||
-- 5. intent_diffs.session_id — make NOT NULL per spec (was nullable in migration 007)
|
||||
-- 6. agent_sessions.agent_type — add lowercase check values per spec
|
||||
-- 7. RLS: add permissive workspace-membership allow policies
|
||||
|
||||
-- ── 1. artboards width/height defaults ───────────────────────────────────────
