+# Phase 18 Plan 01: Template Schema and Migration Summary
+
+**One-liner:** Drizzle `document_templates` table with 7 columns, nullable JSONB fields, soft-delete via `archivedAt`, FK to `form_templates` with no cascade, and auto-generated SQL migration 0012.
+
+## Tasks Completed
+
+| Task | Name | Commit | Files |
+|------|------|--------|-------|
+| 1 | Add documentTemplates table to schema.ts | 9e677f9 | teressa-copeland-homes/src/lib/db/schema.ts |
+| 2 | Generate Drizzle migration | c33c4ec | teressa-copeland-homes/drizzle/0012_ancient_blue_shield.sql |
+
+## What Was Built
+
+Added the `documentTemplates` Drizzle table definition to `schema.ts` immediately after `formTemplates`. The table has exactly 7 columns per D-02:
+
+- `id` — TEXT PRIMARY KEY via `crypto.randomUUID()`
+- `name` — TEXT NOT NULL
+- `formTemplateId` — TEXT NOT NULL, FK to `formTemplates.id` with no `onDelete` (D-06)
+- `signatureFields` — JSONB nullable, typed as `SignatureFieldData[]` (D-04)
+- `archivedAt` — TIMESTAMP nullable, soft-delete sentinel (D-07)
+- `createdAt` — TIMESTAMP NOT NULL DEFAULT NOW()
+- `updatedAt` — TIMESTAMP NOT NULL DEFAULT NOW()
+
+Also added `documentTemplatesRelations` joining to `formTemplates` via `formTemplateId`.
+
+Generated migration `0012_ancient_blue_shield.sql` via `drizzle-kit generate`. The migration contains only a `CREATE TABLE` statement and an `ALTER TABLE ... ADD CONSTRAINT` for the FK — no alterations to existing tables.
+
+## Verification
+
+- `npx tsc --noEmit` — zero errors
+- `ls drizzle/0012_*.sql` — exactly one migration file (0012_ancient_blue_shield.sql)
+- `grep "document_templates" drizzle/0012_ancient_blue_shield.sql` — CREATE TABLE present
+- `grep "form_template_id" drizzle/0012_ancient_blue_shield.sql` — FK column present
+
+## Deviations from Plan
+
+None — plan executed exactly as written.
+
+## Known Stubs
+
+None — this plan is schema-only. No UI or API routes were implemented. Phase 18-02 handles the CRUD API routes.
+
+## Self-Check: PASSED
