3-19: Consider adding indexes on frequently queried columns.

The migration doesn't include indexes on org_id, account, or deleted_at, which are likely to be used in WHERE clauses for common queries:

• org_id: Filtering systems by organization
• deleted_at: Soft-delete queries (e.g., WHERE deleted_at IS NULL)
• Composite index on (org_id, deleted_at): For queries filtering by both

These indexes can be added later once query patterns are established and performance monitoring indicates they're beneficial. Consider adding them in a follow-up migration if query performance becomes a concern.

Example indexes for common query patterns

add_index :systems, :org_id
add_index :systems, :deleted_at
# Or a composite index for queries filtering by both:
add_index :systems, [:org_id, :deleted_at]

migration creates the systems table but omits indexes on frequently queried
columns; add indexes for org_id and deleted_at (and account if used in queries)
and consider a composite index on [:org_id, :deleted_at] to optimize common
WHERE clauses; update the migration by adding add_index :systems, :org_id,
add_index :systems, :deleted_at, optionally add_index :systems, :account, and/or
add_index :systems, [:org_id, :deleted_at] (use the existing create_table
:systems and add_index :systems, :insights_id context to place these).

db/schema.rb (2)

237-237: ⚡ Quick win

Consider adding null: false constraint to groups for consistency.

The groups column has a default value of [] but lacks a null: false constraint, unlike the tags and system_profile columns which both have null: false. This inconsistency means groups could be NULL despite having a default, requiring extra null checks in application code.

For consistency and to prevent NULL/empty-array confusion, consider adding null: false to the groups column definition.

🔧 Suggested improvement

Update the migration file db/migrate/20260601090600_create_systems.rb:

-  t.jsonb :groups, default: []
+  t.jsonb :groups, default: [], null: false

Then regenerate the schema:

rails db:migrate:redo VERSION=20260601090600

In `@db/schema.rb` at line 237, The groups JSONB column currently has default: []
but lacks a null: false constraint; update the migration that creates the
systems table (the CreateSystems migration) to change the column definition for
"groups" to t.jsonb "groups", default: [], null: false so the DB enforces
non-null values, then re-run the migration (redo the migration version that
creates systems) and regenerate the schema so db/schema.rb reflects the new
null: false constraint.

232-232: 💤 Low value

Consider whether account should be required.

The account column is nullable while org_id is required. If account information is always available and should be tracked for all systems, adding null: false would enforce data integrity.

However, if systems can exist without account assignments (e.g., during migration scenarios or when ingesting from external sources that only provide org_id), the current nullable definition is appropriate.

In `@db/schema.rb` at line 232, Decide whether the "account" column should be
required: if it must always be present, add a migration to set any existing NULL
"account" values to a valid default or backfill from related data, then alter
the column to add NOT NULL (e.g., change_column_null :table_name, :account,
false) and add a model-level validation (validates :account, presence: true); if
it can remain optional, leave the schema as-is but consider adding a comment
explaining why it's nullable. Ensure you reference the "account" and "org_id"
columns when making the change so the migration and model validation target the
correct column.
