## Quick Start (on M4 machine)

```bash
# 1. Restore DB
psql -U accusys -d momentry < dev.chunks.sql
psql -U accusys -d momentry < dev.chunk_vectors.sql

# 2. Apply schema migration
psql -U accusys -d momentry -c "
  ALTER TABLE dev.chunks RENAME TO dev.chunk;
  ALTER TABLE dev.chunk DROP COLUMN IF EXISTS old_chunk_id;
  ALTER TABLE dev.chunk DROP COLUMN IF EXISTS chunk_index;
"
psql -U accusys -d momentry -c "
  UPDATE dev.chunk SET chunk_id = substring(chunk_id from 34)
  WHERE chunk_id LIKE (file_uuid || '_%');
  UPDATE dev.chunk_vectors cv SET chunk_id = substring(cv.chunk_id from 34)
  FROM dev.chunk c WHERE c.file_uuid = cv.uuid AND cv.chunk_id LIKE (c.file_uuid || '_%');
"

# 3. Get source code
