+<objective>
+Generate and apply database migration for the new market pricing tables and columns.
+
+Purpose: [BLOCKING] Schema push — database must match code before any API work can proceed. Without this, TypeScript types pass (from config) but runtime queries fail.
+Output: Migration SQL applied to database.

+  <action>
+Run Drizzle migration generation and push:
+
+1. Generate migration: `bun run db:generate`
+   - This reads src/db/schema.ts and produces a SQL migration file in drizzle-pg/
+   - Expected: creates new migration for market_prices table, community_prices table, and new columns on items/thread_candidates
+
+2. Apply migration: `bun run db:push`
+   - Applies the generated migration to the PostgreSQL database
+   - Verify by checking that the migration was applied without errors
+
+3. Verify tables exist by running a quick query or checking the migration output
+
+Note: Drizzle ORM detected, push command is `bun run db:push` (per project CLAUDE.md). Non-TTY compatible — no interactive prompts expected.
+  </action>
+  <acceptance_criteria>

+    - Migration SQL contains ALTER TABLE thread_candidates ADD COLUMN found_price_cents
