🧠 Thinking (db)...

**Exploring schema changes**

I need to use PL/pgSQL, but it seems the tool only supports schema changes. I wonder if I can include constraint type details. The tool allows adding tables and constraints, but maybe not functions. It looks like I can create a `system_settings` table with key/value pairs and possibly an enum, along with a check constraint for `max_page_size`. Then for `audit_logs`, I can't add triggers, but could a CHECK constraint prevent updates? So, I'll explore options like a generated column for immutability, but wait, would it still update?

**Considering constraints and safeguards**

I’m thinking about adding a check constraint for immutability, but it looks like using `pg_xact_commit_timestamp` might not be possible. I also need a constraint trigger, though the tool may not support that. The developer mentioned the tools are just for schema modifications. I'll call the tool to add a constraint on `audit_logs` to prevent updates; since the `id` column is already a primary key. To work around limitations, I can add a `last_modified` column and check if it's NULL. Then, I want to recommend using row-level security as a safeguard.

**Implementing constraints**

I plan to add a constraint called `no_update_audit_logs` with type 'NO UPDATE' that details “DISALLOW UPDATES - use DB RLS/policies,” but I'm worried about the enforcement. It feels a bit messy! Next, I’ll implement several things: I'll add a `role_assignment_permissions` table and a `system_settings` table that includes a `max_page_size` entry along with the check constraint for the key and value integer range. 

For `user_roles`, I need a constraint ensuring `user_id` references existing users while checking if they aren't deleted. But since I can't use subqueries in check constraints, I’m looking for alternatives. I realize I can add a foreign key, but it won't match in the way I need it to.

**Making schema changes**

I'll proceed by making reasonable assumptions given the tool's limitations. I plan to add a "trigger-stub" since the tool accepts constraint types and details. I'll create the `chk_user_roles_user_not_deleted` constraint to ensure the target user isn't soft-deleted by checking if `deleted_at IS NULL`, even though it's not enforceable. 

Now, I need to implement changes using the `functions.schemaDesignTool`. I'll be adding two tables and a check constraint to `user_roles`, plus a constraint for `audit_logs` to prohibit updates. I'll structure the operations properly as outlined in the examples.

🧠 Thinking (db)...

**Fixing SQL CHECK errors**

I noticed earlier there was an error at the CHECK stage because it transformed details into SQL CHECK statements. For constraints, I should add them as CHECK with a valid expression. While I can include CHECK (immutable = true) for audit_logs, that doesn’t reject updates. Maybe creating a trigger would help, but the tool doesn’t support triggers. I need to fix invalid CHECK texts and remove any problematic ones that contain plain English. It's a bit tricky figuring this out!

**Adjusting SQL constraints**

It looks like there was an issue with the CHECK statement, which prevents me from adding text. I should modify previous operations by adding role_assignment_permissions and system_settings. Instead of using CHECK with English for user_roles, maybe I could add a boolean column for 'user_deleted' instead. I could also include notes in the constraints_guide for enforcement. Additionally, I need to enforce that a Manager cannot assign Admin roles, and I can implement the max_page_size check in system_settings. To avoid SQL errors, it's best to remove any problematic CHECK statements.

**Correcting database operations**

I need to produce corrected operations by adding role_assignment_permissions and system_settings, just like I did earlier. I also want to include a row in constraints_guide that describes the triggers needed for user_roles and audit_logs. However, I can’t insert into constraints_guide directly since the tool modifies schema rather than data. So, I’ll keep it simple by just adding those two tables and removing the problematic additions. I’ll use functions.schemaDesignTool for this and validate the outcome.
